I think a good and simple solution is to use an adorner to render the masking symbols as an overlay of the original input.
Show the adorner to render the masking characters while hiding the password by setting the foreground brush to the background brush.
The following example shows how to use an `Adorner` to decorate the `TextBox`.
I have removed some code to reduce the complexity (the original library code also contained validation of input characters and password length, event logic, routed commands, `SecureString` support, low-level caret positioning to support any font family for those cases where the font is not a monospace font and password characters and masking characters won't align correctly etc. and a much more complex default `ControlTemplate`). The current version therefore only supports monospace fonts. The supported fonts have to be registered in the constructor. You could implement monospace font detection instead.
However, it's a fully working example (happy easter!).

The best way to test more complex AWS lambda functions where development time and local infrastructure is the key. Is usage of their official [AWS Lambda docker image][1].
Simple Dockerfile example from documentation:
```
FROM public.ecr.aws/lambda/python:3.8
# Copy function code
COPY app.py ${LAMBDA_TASK_ROOT}
# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD [ "app.handler" ]
```

I have a Discord bot and I want it to delete a "Loading..." message. However it just deletes the user message for the command
```
@client.command()
async def run(ctx):
await ctx.send("Loading...")
await ctx.message.delete()
await ctx.send("Loading Complete!")
```
This raises insufficient permissions as it is trying to delete the user message instead of the message it just sent.
What am I doing wrong here? |

Just set the major unit to 1 so the axis counts 1 - 8 by 1s.
Add to the x-axis setting
```
chart.set_x_axis({'name': 'X Axis'})
```
```
chart.set_x_axis({
'name': 'X Axis',
'major_unit': 1, # set major unit to 1
})
```
[![Chart with major unit set to 1][1]][1]
<br>
You could also add a label to the Trend Line like;
```
# Add line series to the chart
chart.add_series({
'categories': '=Sheet1!$C$1:$C$2', # Adjusted for new data range
'values': '=Sheet1!$D$1:$D$2', # Adjusted for new data range
'line': {'type': 'linear'}, # Adding linear trendline
'data_labels': {'value': False, # Add Data Label
'position': 'below',
'category': True,
}
})
```
All this is doing is labeling your trend line, with the lower label sitting on the X-Axis.<br>
You'll notice the value is set at start and end points but I don't think there is any means to remove the top textbox using Xlsxwriter. It can be removed manually however simply by clicking the textbox twice and then use the delete key.<br>
And for that matter you could manually move the bottom textbox to align with the other numbers too if you like

When I debug locally and run `GetEntityReport` with no results, I get a http 404, which is great. When I post this to the remote server the logs report 404, but 403 seems to be returned...which is not great.
Here is my controller, I only included the function that is causing an issue:
namespace ReportServices.Controllers
{
private readonly IReportServiceRepo _repository;
private readonly IMapper _mapper;
private readonly ILogger<ReportServicesController> _logger;
public ReportServicesController(IReportServiceRepo repository, IMapper mapper, ILogger<ReportServicesController> logger)
{
_repository = repository;
_mapper = mapper;
}
// GET api/reportservice/entities/{id}/2022/11/test

[ProducesResponseType(StatusCodes.Status404NotFound)]
public ActionResult<IList<ReportReadSimpleDto>> GetEntityReport(int entityId, int year, int month, string title)
{
var reportsItem = _repository.SearchForReport(entityId, year, month, title);
if (reportsItem != null && reportsItem.Count > 0)
{
return Ok(_mapper.Map<IEnumerable<ReportReadSimpleDto>>(reportsItem));
}
return NotFound("No report found for this criteria.");
}
}

This is a screenshot of Swagger query (https://i.stack.imgur.com/4v3xX.png)
The hosting bundle is installed on the remote server and is .NET 8. Could that be causing this? Maybe an IIS setting?
Any ideas?
Thank you in advance!
If I use a query that has a resulting object, the result is perfect (200 OK). Weird. |
C# ASP.NET Core Web API incorrectly returning 403 on remote server |
To expand on Guru's answer, When you specify `AsNoTracking()` EF populates entities based on only what comes back from the database, it will not go to the tracking cache to fill in references, and the returned entities will not work with lazy loading which would otherwise fill in non-included references if you have lazy loading enabled.
In the case where you want to load *all* entity1's then using `AsNoTrackingWithIdentityResolution` should be enough. However, if you put any kind of filter on which Entity1's you load initially then you should eager load those as well, as per cleftharis's comment, but also use `AsNoTrackingWithIdentityResolution` to ensure that the Entity2.Entity1 referencing back to the initial one you load point to the same reference:
var entities = Context.Entity1s
.Where(x => /* some condition */)
.Include(x => x.Entity2)
.ThenInclude(x => x.Entity1s)
.AsNoTrackingWithIdentityResolution();
The reason is that otherwise `AsNoTrackingWithIdentityResolution` will only populate the Entity1 references in the Entity2s based on which Entity1s were loaded. So if an entity2 had a reference to an entity 1 that wasn't returned in the root query's conditions, it won't be populated in the results.
Alternatively, If you instead use:
var entities = Context.Entity1s // with, or without a Where condition...
.Include(x => x.Entity2)
.ThenInclude(x => x.Entity1s)
.AsNoTracking();
... then the results will appear to work, but a big problem is that:
var first = entities.First();
var childsParent = first.Entity2.Entity1s.Single(x => x.Id == first.Id);
bool sameReference = object.ReferenceEquals(first, childsParent);
"sameReference" in this case would be `false`. While they contain the same row they would be different, separate instances of an entity class. Ensuring the references to the same row use the same instance is the primary purpose for using `AsNoTrackingWithIdentityResolution`.

I'm practicing using React queries.
In this code, I expected to invalidate only the ['test'] query key.
However, the ['todos'] query is invalidated and the data is received again from the server.
Applying useQuery options does not change the results.
I would appreciate some help as to what the problem is.
```
const { data: todos } = useQuery({
queryKey: ["todos"],
queryFn: () => getTodos(),
});
const { mutate: handleAddTodo } = useMutation({
mutationFn: addTodo,
onSuccess: () => {
queryClient.invalidateQueries(["test"]);
},
});
```
- Applying useQuery options,
- Applying default options

When using **kubectl get nodes**, the connection refused error you are experiencing is probably caused by the way your Ansible playbook handles the kubeconfig file.
**See how to resolve the problem and make calico deployment possible here.**
- Make sure the master node's Kubernetes API server is up and working by checking its port 6443 This can be accomplished by confirming that no firewall rules are preventing the connection and monitoring the kube-apiserver service's status.
- Due to security considerations, it is generally discouraged to run Ansible jobs with root capabilities. Instead, create a special user for Kubernetes management and configure Ansible to utilize that user.
- Inside the playbook once the kubeconfig has been copied to a non-root user's home directory.Ensure that the user has the necessary permissions, and utilize the file module's owner and group options to properly specify ownership and group.
- Change the playbook's kubectl get nodes task to point to the non-root user's kubeconfig directory.
- Using the official calico for Kubernetes CNI provider on [Ansible Galaxy][1], you can deploy calico once you have a functional kubeconfig established for your non-root user.
Instead of pasting the kubeconfig directly into the playbook of enhanced security advantage, think about storing it as a Kubernetes secret. Using [Ansible Vault][2] to safely handle private data, such as Kubeadm tokens

In my case, I was receiving a custom class on the hub method, but the properties of that class had no setters, so all properties were default values.
So each property needs `{ get; set; }` to be assigned during deserialization. |

1. The original implementation changes the original list. To create a new list you need to return a pointer to *copy* of the smallest node or NULL. To emphasize that I made the argument constant with `const Node *head`.
1. Observe that `pairWiseMinimumInNewList_Rec()` either returns a copy of 1st node, 2nd node or NULL (3 values). The recursive call is either two nodes head or NULL (2 values). For a total of 6 cases. If you make the values conditional instead of expressions you can collapse that into a single return statement.
```
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct Node {
int val;
struct Node *pt_next;
} Node;
Node *linked_list_new(int val, Node *pt_next) {
Node *n = malloc(sizeof *n);
if(!n) {
printf("malloc failed\n");
exit(1);
}
n->val = val;
n->pt_next = pt_next;
return n;
}
Node *linked_list_create(size_t n, int *vals) {
Node *head = NULL;
Node **cur = &head;
for(size_t i=0; i < n; i++) {
*cur = linked_list_new(vals[i], NULL);
if(!head) head = *cur;
cur = &(*cur)->pt_next;
}
return head;
}
void linked_list_print(Node *head) {
for(; head; head=head->pt_next)
printf("%d->", head->val);
printf("NULL\n");
}
void linked_list_free(Node *head) {
while(head) {
Node *tmp = head->pt_next;
free(head);
head=tmp;
}
}
Node *pairWiseMinimumInNewList_Rec(const Node* head) {
return head ?
linked_list_new(
(head->pt_next && head->val < head->pt_next->val) || !head->pt_next ?
head->val :
head->pt_next->val,
pairWiseMinimumInNewList_Rec(head->pt_next ? head->pt_next->pt_next : NULL)
) :
NULL;
}
int main() {
Node *head=linked_list_create(7, (int []) {2,1,3,4,5,6,7});
Node* head_dest=pairWiseMinimumInNewList_Rec(head);
linked_list_free(head);
linked_list_print(head_dest);
linked_list_free(head_dest);
}

i have a Steam Deck and would like to install GLFW on a Steamdeck, so that VSCode can find the Libary, i use Cmake. I used Cmake on another linux machine with no problems. I think its related to the steam deck and steam os.
I a location in with the following files in usr/lib/cmake/glfw3 :
- glfw3Targets.cmake,
- glfw3Targets-noconfig.cmake,
- glfw3ConfigVersion.cmak,
- glfw3Config.cmake
Also there are two header files in /usr/include/GLFW called:
- glfw3.h
- glfw3native.h
Also i have this so's:
- /usr/lib/libglfw.so
- /usr/lib/libglfw.so.3
- /usr/lib/libglfw.so.3.3
In the main.cpp file the #include \<GLFW/glfw3.h\> do not work.
My Cmake file looks now like this:
```
cmake_minimum_required(VERSION 3.12)
project(test)
# Add executable
add_executable(test src/main.cpp)
# Specify the path to GLFW include directory
set(GLFW_INCLUDE_DIR "/usr/include" CACHE PATH "Path to GLFW include directory")
# Specify the path to GLFW library directory
set(GLFW_LIBRARY_DIR "/usr/lib" CACHE PATH "Path to GLFW library directory")
# Add GLFW include directory
target_include_directories(test PRIVATE ${GLFW_INCLUDE_DIR})
# Link GLFW library to your executable
target_link_libraries(test ${GLFW_LIBRARY_DIR}/libglfw.so)
```
Maybe some one with a better understanding of cmake, c and linux can help me.
Thank you in advance.
I tried different combinations of cmake files with find() and so on. Looked into the internet, and used Chat GPT to find a solution.
Reinstalled with
```
sudo pacman -S glfw-x11
```
glfw again on the steam deck.

I saw this piece of code in MDN while I was learning some syntax about Class in JavaScript today, which really confused me. [Here it is][1]:
```javascript
class Rectangle {
height = 0;
width;
constructor(height, width) {
this.height = height;
this.width = width;
}
}
```
If I create an instance of Rectangle without passing into any arguments, the default value of height 0 doesn't work on the instance.
```javascript
const rec = new Rectangle();
// { height: undefined, width: undefined }
```
My question is "Is this piece of code is a bad practice?". If a class filed has been assigned inside the constructor, we shouldn't give a defalut valut to the class outside the constructor because it will always not work. Instead, we can set a default of a class field that hasn't been assigned inside the constructor like below:
```javascript
class Rectangle {
height = 10;
width;
constructor(width) {
this.width = width;
}
}
const rec = new Rectangle();
console.log(rec);
// { height: 10, width: undefined }
```
The defalut value works in this case.

I'm encountering an issue with building a responsive webpage. When testing the page's responsiveness, the width extends beyond the device's width for some reason.
I've tried removing various parts of the code, and I've found that the "introduction" div seems to be causing the problem. When I remove it, the webpage returns to the normal width. Can anyone help me identify what's wrong with my code?
Here's the relevant HTML and CSS for the introduction div :-
(HTML):
<div class="introduction row align-items-start">
<div class="gap row">
<!-- Gap in between a ID and text and image -->
</div>
<div class="row">
<div class="intro-text col">

I have a program written in the Delphi Programming Language that I have to convert to C# using Visual Studio. I have done most of the conversion but ran into a couple of challenges with `VarArrayCreate`.
What I have is this: `Line := VarArrayCreate([0, 1], varVariant);`
I can't seem to figure out a conversion or substitute for the `VarArrayCreate`.
I know that the object in C# can be used for a Variant substitute but the above has me stuck.
any help would be great.
I have added the Delphi code below. I am interested in the procedure `TForm1.Button3Click(Sender: TObject);` procedure:

I don't know why black ducks are smaller than the regular ones. The svg files dimensions (px) are exactly the same and I can't find where is the problem.
Can anyone help me to solve it?
Thanks in advance!!!
I've checked the svg files and both are exactly the same size. About the Javascript code I can't find anything beyond the render scale but I think it shouldn't be the problem. |

I am trying to create a structure `Student` which contains q substructures named `Course`. Each `Course` is a structure with a credit and point `int` values.
How do I set up my `Student` structure to have an integer number of `Course` structures within it? Thanks
```
struct Student{
int q;
Course course[q];
};
struct Course{
int credit;
int point;
};
```

How does it set the properties data and create a connection?
RowSetFactory factory = RowSetProvider.newFactory();
JdbcRowSet jdbcRowSet = factory.createJdbcRowSet();
jdbcRowSet.setUrl("..................");
jdbcRowSet.setUsername(".............");
jdbcRowSet.setPassword("..............");

This is because the generic type `S` can have more keys than just `"a"` and `"b"` — that's what the `extends` keyword means in that position: that the generic type `S` must be [constrained](https://www.typescriptlang.org/docs/handbook/2/generics.html#generic-constraints) by `Pick<Test, "a" | "b">` (not that it ONLY has keys `"a"` and `"b"`.
TypeScript is [structurally-typed](https://www.typescriptlang.org/docs/handbook/type-compatibility.html) (more [here](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html#structural-type-system) and [here](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes-func.html#structural-typing)), so supplying a generic type that satisfies `Pick<Test, "a" | "b">` that **also** has an [index signature](https://www.typescriptlang.org/docs/handbook/2/objects.html#index-signatures) of `symbol` keys with `unknown` values will be accepted by the compiler…
[TS Playground](https://www.typescriptlang.org/play?noUncheckedIndexedAccess=true&removeComments=true&target=99&jsx=4&exactOptionalPropertyTypes=true&inlineSourceMap=true&inlineSources=true&isolatedModules=true&noImplicitOverride=true&noErrorTruncation=true&ssl=13&ssc=1&pln=21&pc=75#code/JYOwLgpgTgZghgYwgAgCoQM5mQbwFACQcAXMllKAOYDchARqSAK4C2d0tBCpdA9rwBsIcELQC+ePEOxwoUUuSoBtALrIAvMlW08MJiARhgvEMkhYAPAGVkEAB6QQAEwzIACsAQBrC+iwAaZAAiOCDkAB9guiCAPkDUWwcIZ1cvCABPXhhkKxiACgA3OAFSVFUASlxCWSgNZCKBcUkwdIAHFAAxfjr8IgUwChAaekZWdihOJTT0hXS2QRVSfS8QXgB3UTwxHQQTLGRQVqYwUjzprOQu3nLVOqUrOb4BPKCYfiDywJCgr+iVHXMYAsV0C52yV3yh2O5WoyAA9HDkAB5LyBOjHMiPQQHVyrGQYDDASggOB0IRmXhkAZUPBAA)
```lang-ts
type Foo = {
a: string;
b: number;
[key: symbol]: unknown;
};
const input: (keyof Foo)[] = [Symbol("foo"), "a", "b"];
test<Foo, keyof Foo>(input); // Ok, but symbol is not assignable to string
```
…but `symbol` is not assignable to `string`, so it would be a type error to accept an array of such values (or any other non-string value).
In the second code block example of your question you provided this code and question:
```lang-ts
type S = Pick<Test, "a" | "b">;
type T = keyof S;
const val: T[] = [];
arr = val; // why it is ok?
```
There, `S` is a type that looks like `{ a: string; b: number }` and T is the union of its keys, which is `"a" | "b"`. An array of `"a"` and `"b"` values are assignable to `string`, so there's no problem there.
A modified version of your `test` function that uses these types would look like this…
[TS Playground](https://www.typescriptlang.org/play?noUncheckedIndexedAccess=true&removeComments=true&target=99&jsx=4&exactOptionalPropertyTypes=true&inlineSourceMap=true&inlineSources=true&isolatedModules=true&noImplicitOverride=true&noErrorTruncation=true#code/JYOwLgpgTgZghgYwgAgCoQM5mQbwFACQcAXMllKAOYDchARqSAK4C2d0tBCpdA9rwBsIcELQC+ePEOxwoUUuSoBtALrIAvMlW08MJiARhgvEMkhYAFADc4A0hYDWEAJ68YyAArAEDgDzosABpkACI4EOQAH1C6EIA+AEpVBNxCWSgNZBsBcUkwZwAHFAAxfkz8IgUwChAaekZWdihOJSdnBWc2QRVSfQcQXgB3UTwxHQQTLGRQAqYweza3ZFLeJLVNJQBlTr4BCxCYfhCE4LCQ09iVHXMwCxm5hNogA)
```lang-ts
function test(val: (keyof Pick<Test, "a" | "b">)[]) {
arr = val;
}
```
> Note that `keyof Pick<Test, "a" | "b">` is just `"a" | "b"`.
…and attempting to provide an array of values that includes a non-string will produce a compiler diagnostic error:
```lang-ts
type Foo = {
a: string;
b: number;
[key: symbol]: unknown;
};
const input: (keyof Foo)[] = [Symbol("foo"), "a", "b"];

I created an app that generates keyword searchable PDF files with tesseact, but when the PDF file is created, the pages are randomly reordered by one page every few dozen pages. How can I get the PDF file to be created in the order in which the image files were read?

results.sort(key=lambda x: x[0])
for i, (_, _, page) in enumerate(results):

print(f"\rProcessing: {i+1}/{total_files}", end="")
sys.stdout.flush()
if page:
pdf = PyPDF2.PdfReader(io.BytesIO(page))
for pageNum in range(len(pdf.pages)):
pdf_writer.add_page(pdf.pages[pageNum])
print("\nAll files have been processed. Compiling into PDF...")

How can I get the PDF file to be created in the order in which the image files were read? |
The project folder you have opened is not the parent folder of "admin.py" and "admin_instance.py" (or the path of "admin.py" would be relative instead of "c: > ..."). So those files are being treated as isolated Python code files.
Select VScode menu "File" -> "Open Folder" and open "C:\...\Python work\importing", and you will see the difference. |
Use case: I want to generate no-passphrase 2048-byte RSA keypairs I can use for service accounts to authenticate to Snowflake. I need to generate them programmatically to make key rotation practical.
Snowflake docs provide [a manual procedure using OpenSSL at this link](https://docs.snowflake.com/en/user-guide/key-pair-auth.
The code below creates keypairs, and they work with snowflake/snowflake connector for python. It is lightly modified from examples in the cryptography documents that create other formats.
Questions:
1) The standard python "cryptography" manual cautions about people like me who don't understand cryptography messing around with hazmat libraries. Do you see anything relevant to security problem with the way I am generating keys? Assuming I can securely get them from point of generation to the place where they are used, is this okay?
2) Would it be safer automate by running openssl in a subprocess, using the Snowflake documented procedures?
```python
from cryptography.hazmat.primitives import serialization as crypto_serialization
from cryptography.hazmat.primitives.asymmetric import rsa
from cryptography.hazmat.backends import default_backend as crypto_default_backend
key = rsa.generate_private_key(
backend=crypto_default_backend(),
public_exponent=65537,
key_size=2048
)
private_key = key.private_bytes(
crypto_serialization.Encoding.PEM,
crypto_serialization.PrivateFormat.PKCS8,
crypto_serialization.NoEncryption()
)
public_key = key.public_key().public_bytes(
crypto_serialization.Encoding.PEM,
crypto_serialization.PublicFormat.SubjectPublicKeyInfo
)
with open("/tmp/pubkey.pub", "wt") as pub:
pub.write(public_key.decode("utf-8"))
with open("/tmp/privkey.p8", "wt") as priv:
priv.write(private_key.decode("utf-8"))
```
|
Are there poor practices in this use of python cryptography package to generate RSA keypair? |

Thank you to user @trojanfoe again, who said
"You are overthinking the issue. To move `A` towards `B` at a given speed you need to do nothing more than `auto dir = normalize(B - A); A += dir * (speed * deltaTime);`"
Below is my code modified to incorporate this much simpler solution (this code already has a deltaTime function elsewhere which fixes the intervals between frame rendering.)
```
void Enemy::attemptMove(sf::Vector2f t_playerPos)
{
sf::Vector2f direction = t_playerPos - enemyLocation; // playerPos-enemyPos (direction to player)
float hyp;
// normalising the vector
hyp = sqrtf(abs(direction.x * direction.x) + abs(direction.y * direction.y));
hyp = abs(1.f / hyp); // inverse of pythagoras theorem hypothenuse
direction.x = hyp * direction.x;
direction.y = hyp * direction.y; // sqrt(x^2 + y^2) should equal 1
move(direction);
}
void Enemy::move(sf::Vector2f t_movement)
{
enemyLocation += t_movement; // update enemy location
enemySprite.setPosition(enemyLocation); // set enemy position to updated location
}

I am implementing user authorization using Google using next auth.
The logic is as follows:
1. The user clicks on the login button using Google, after which he is
taken to a page with an account selection.
2. After selecting an account, it is returned back to the page.
3. When the page is rendered, the following useEffect is executed:
```
const { data: session } = useSession();
const dispatch = useDispatch<any>();
useEffect(() => {
console.log(session);
if (session) {
dispatch(
logInWithGoogle({
type: "google",
email: session?.user?.email,
name: session?.user?.name,
socialID: session?.user?.id,
})
);
console.log("qwe");
}
}, [session]);
```
4. *loginWithGoogle* sends a request to the server, and most
importantly, RECEIVES a response.
```
export const logInWithGoogle = createAsyncThunk("user/logInWithGoogle", async (data: loginWithGoogleData) => {
const formData = new FormData();
formData.append("type", `${data.type}`);
formData.append("email", `${data.email}`);
formData.append("name", `${data.name}`);
formData.append("socialID", `${data.socialID}`);
const response = await serviceFetch.post("/auth/social-networks", undefined, formData);
const res = await response.json();
if (res.result && !Object.keys(res.errors).length) {
updateTokenStorage(res.data.token);
console.log(res);
data.router.replace("/profile");
}
return res;
});
```
But the data in the storage itself appears only after the page is reloaded, why is that? The session is available immediately after authorization. |
Data in global storage appears only after the page is reloaded. Redux |

When I tried to make more changes to the file, Wordpress started displaying the following error message:
> Something went wrong. Your change may not have been saved. Please try again. There is also a chance that you may need to manually fix and upload the file over FTP.
When I try to edit my website pages, I started getting the following error message now:

JavaScript svg scale issue with matter.js |

Coding a two-dimensional, dynamically allocated array of `int` is a non-trivial task. If you use a _double pointer_, there are significant memory allocation details. In particular, you need to check every allocation attempt, and, if any one fails, back out of the ones that didn't fail, without leaking memory. And, finally, to take a term from the C++ lexicon, you need to provide some equivalent of the _Rule of Three_ functions used by a C++ _RAII_ class.
A two-dimensional array of `int` with `n_rows` and `n_cols` should probably be allocated with a single call to `malloc`:
```lang-c
int* data = malloc(n_rows * n_cols * sizeof int);
```
With this approach, you have to write indexing functions that accept both `row` and `col` subscripts.
The program in the OP, however, takes the _double pointer_ route, and allocates an _array of pointers to int_. The elements in such an array are `int*`. Thus, the argument to the `sizeof` operator must be `int*`.
```lang-c
int** data = malloc(n_rows * sizeof (int*)); // step 1.
```
Afterwards, you run a loop to allocate the columns of each row. Conceptually, each row is an array of `int`, with `malloc` returning a pointer to the first element of each row.
```lang-c
for (size_t r = 0; r < n_rows; ++r)
data[r] = malloc(n_cols * sizeof int); // step 2.
```
The program in the OP errs in step 1.
```lang-c
// from the OP:
ret = (int **)malloc(sizeof(int) * len); // should be sizeof(int*)
```
Taking guidance from the [answer by @Eric Postpischil](https://stackoverflow.com/a/78248309/22193627), this can be coded as:
```lang-c
int** ret = malloc(len * sizeof *ret);
```
The program below, however, uses (the equivalent of):
```lang-c
int** ret = malloc(len * sizeof(int*));
```
#### Fixing memory leaks
The program in the OP is careful to check each call to `malloc`, and abort the allocation process if any one of them fails. After a failure, however, it does not call `free` to release the allocations that were successful. Potentially, therefore, it leaks memory. It should keep track of the row where a failure occurs, and call `free` on the preceding rows. It should also call `free` on the original array of pointers.
There is enough detail to warrant refactoring the code to create a separate header with functions to manage a two-dimensional array. This separates the business of array management from the application itself.
Header `tbx.int_array2D.h`, defined below, provides the following functions.
- _Define_ – `struct int_array2D_t` holds a `data` pointer, along with variables for `n_rows` and `n_cols`.
- _Make_ – Function `make_int_array2D` handles allocations, and returns a `struct int_array2D_t` object.
- _Free_ – Function `free_int_array2D` handles deallocations.
- _Clone_ – Function `clone_int_array2D` returns a _deep copy_ of a `struct int_array2D_t` object. It can be used in initialization expressions, but, in general, should not be used for assignments.
- _Swap_ – Function `swap_int_array2D` swaps two `int_array2D_t` objects.
- _Copy assign_ – Function `copy_assign_int_array2D` replaces the existing value of an `int_array2D_t` object with a _deep copy_ of another. It performs allocation and deallocation, as needed.
- _Move assign_ – Function `move_assign_int_array2D` deallocates an existing `int_array2D_t` object, and replaces it with a _shallow copy_ of another. After assignment, it zeros-out the source.
- _Equals_ – Function `equals_int_array2D` performs a _deep comparison_ of two `int_array2D_t` objects, returning `1` when they are equal, and `0`, otherwise.
```lang-c
#pragma once
// tbx.int_array2D.h
#include <stddef.h>
struct int_array2D_t
{
int** data;
size_t n_rows;
size_t n_cols;
};
void free_int_array2D(
struct int_array2D_t* a);
struct int_array2D_t make_int_array2D(
const size_t n_rows,
const size_t n_cols);
struct int_array2D_t clone_int_array2D(
const struct int_array2D_t* a);
void swap_int_array2D(
struct int_array2D_t* a,
struct int_array2D_t* b);
void copy_assign_int_array2D(
struct int_array2D_t* a,
const struct int_array2D_t* b);
void move_assign_int_array2D(
struct int_array2D_t* a,
struct int_array2D_t* b);
int equals_int_array2D(
const struct int_array2D_t* a,
const struct int_array2D_t* b);
// end file: tbx.int_array2D.h
```
With these functions, code for the application becomes almost trivial:
```lang-c
// main.c
#include <stddef.h>
#include <stdio.h>
#include "tbx.int_array2D.h"
size_t ft_strlen(char* str)
{
size_t count = 0;
while (*str++)
count++;
return (count);
}
struct int_array2D_t parray(char* str)
{
size_t len = ft_strlen(str);
struct int_array2D_t ret = make_int_array2D(len, 2);
for (size_t r = ret.n_rows; r--;) {
ret.data[r][0] = str[r] - '0';
ret.data[r][1] = (int)(len - 1 - r);
}
return ret;
}
int main()
{
char* str = "1255555555555555";
struct int_array2D_t ret = parray(str);
for (size_t r = 0; r < ret.n_rows; ++r) {
printf("%d %d \n", ret.data[r][0], ret.data[r][1]);
}
free_int_array2D(&ret);
}
// end file: main.c
```
#### tbx.int_array2D.c
Function `free_int_array2D` has been designed so that it can be used for the normal deallocation of an array, such as happens in function `main`, and also so that it can be called from function `make_int_array2D`, when an allocation fails.
Either way, it sets the `data` pointer to `NULL`, and both `n_rows` and `n_cols` to zero. Applications that use header `tbx.int_array2D.h` can check the `data` pointer of objects returned by function `make_int_array2D` and function `clone_int_array2D`. If it is `NULL`, then the allocation failed.

Looks like you're trying to create the directories if your user chooses one of 3 text phrases and the directory doesn't already exist, and complain to your user if they choose something other than the 3 text phrases. I would treat each of those cases separately:
$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")
$AcceptableText = @("Specific Text1","Specific Text2","Specific Text3")
If ($text -in $AcceptableText)
{
If (!(Test-Path $Path\$text))
{
new-item -ItemType directory -path $Path\$text
}
}
Else
{
write-host "invalid input"
}
Or you could test for the existence of the directory first like this:
$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")
$AcceptableText = @("Specific Text1","Specific Text2","Specific Text3")
If (!(Test-Path $Path\$text))
{
If (($text -in $AcceptableText))
{
new-item -ItemType directory -path $Path\$text
}
Else
{
write-host "invalid input"
}
}
Edit
---
Or, if you want to be tricky and avoid the Test-Path (as suggested by @tommymaynard), you can use the following code (and even eliminate the Try|Catch wrappers if you don't want error checking)
$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")
$AcceptableText = @("Specific Text1","Specific Text2","Specific Text3")
If (($text -in $AcceptableText))
{
try { mkdir -path $Path\$text -ErrorAction Stop } #Change to -ErrorAction Ignore if you remove Try|Catch
catch [System.IO.IOException] { } #Do nothing if directory exists
catch { Write-Error $_ }
}
Else
{
write-host "invalid input"
}
Edit

Sometimes, something may go wrong with `npm install` due to network trouble or something. So if you keep on facing the problem repeatedly, it's better to erase `node_modules folder` and re-run `npm install` command. |
Rendering a component via a ternary or switch statement does not have any effect on how React will render them and whether they get unmounted or not in between renders. It seems your issue comes from both statements having different behavior;
```jsx
{cardValue === 'A' ? <ComponentA/> : <ComponentB>}
````
This is basically if "A", render `ComponentA` and in all other cases, render `ComponentB`.
But your switch statement does something different;
```jsx
switch (cardValue) {
case 'A':
return <ComponentA />;
case 'B':
return <ComponentB />;
default:
return null;
}
```
If "A" render `ComponentA` and if "B", render `ComponentB`, and in all other cases render null. Based on this, I am concluding your `cardValue` is not just "A" or "B", but can be another value as well, or possibly temporarily while switching from "A" to "B". To make both statements equal, you could use this for your switch statement:
```jsx
switch (cardValue) {
case 'A':
return <ComponentA />;
default:
return <ComponentB />;
}

i have a Steam Deck and would like to install GLFW on a Steamdeck, so that VSCode can find the Libary, i use Cmake. I used Cmake on another linux machine with no problems. I think its related to the steam deck and steam os.
I a location in with the following files in usr/lib/cmake/glfw3 :
- glfw3Targets.cmake,
- glfw3Targets-noconfig.cmake,
- glfw3ConfigVersion.cmak,
- glfw3Config.cmake
Also there are two header files in /usr/include/GLFW called:
- glfw3.h
- glfw3native.h
Also i have this so's:
- /usr/lib/libglfw.so
- /usr/lib/libglfw.so.3
- /usr/lib/libglfw.so.3.3
In the main.cpp file the #include \<GLFW/glfw3.h\> do not work.
My Cmake file looks now like this:
```
cmake_minimum_required(VERSION 3.12)
project(test)
# Add executable

Maybe some one with a better understanding of cmake, c and linux can help me.
Thank you in advance.
I tried different combinations of cmake files with find() and so on. Looked into the internet, and used Chat GPT to find a solution.
Reinstalled with
```
sudo pacman -S glfw-x11

I have a customer app where they request services. On the screen I'm working on, they can choose up to three dates. However, what I'm having trouble with is I'm unable to append the selected dates to the array and then upload it to the Firestore document. How would you go about this? Should I rewrite my `handleDateCreationTapped()` function to add to my array? Thank you!

you were close with your first approach, you just got the logic a little wrong. the substition removes `list` if it is present in the variable link, meaning the condition will `not` be true if the string list is present. therefore:
`If defined link If /i Not "%link:list=%" == "%link%" goto:Playlist`
Would be the correct logic.
To safely expand user input, it is advisable to perform such comparisons with `Setlocal enabledelayedexpansion` active and using: `If defined link If /i Not "!link:list=!" == "!link!" goto:Playlist` |
By default mongoose will buffer commands; this is to manage the possible intermittent disconnections with MongoDB server.
By default, under the event of a disconnection, mongoose will wait for 10 seconds / 10000 milliseconds before throwing an error. This is what happens in your case. Mongoose throws an error after retrying the given insertion command for 10 seconds.
Therefore the main problem is mongoose could not establish server connection in 10 seconds.
This is something to check further. In order to check this connection issue, there needs to be an error handler provided to the connection statement shown below.
let conn = mongoose.connect("mongodb://localhost:27017/todo")
Thanks to @jqueeny, he has given you a code snippet for doing the same. Once you have trapped this error, the error message would help you to know the reason for failing connection.
The hostname - localhost, specified in the connection string has enough potential for this kind of connection issues. You can see the details of a similar case enclosed here. It suggests to replace localhost with IP address.

I have a page in Laravel that has a start date, a deadline, and an end date. I want to calculate and display the final date when I enter the number of days (deadline). I have used Laravel Collective for the controls.
start date:
{!! Form::text('StartDate', jdate($task->StartDate)->format('Y-m-d'), ['class'=>'myform-control]) !!}
deadline:
{!! Form::text('Deadline', null, ['class'=>'myform-control','style'=>'width:50px;']) !!}
<script>
$('#Deadline').change(function()
{
const dval =parseInt($('#Deadline').val());
const StartDate=document.getElementById("StartDate").value;
const startdateToEnglish= StartDate.toEnglishDigit();
const startdateToEngArray = startdateToEnglish.split('-').map(Number);
var inputF = document.getElementById("EndDate");
edate = new persianDate(startdateToEngArray).add('days', dval).format('YYYY-MM-DD');
console.log(startdateToEngArray,dval,edate);
inputF.value = edate;
});
</script>
and end date:
{!! Form::text('EndDate', jdate($task->EndDate)->format('Y-m-d'), ['class'=>'myform-control observer-example','style'=>'width:180px;','old'=>'EndDate']) !!}
I have implemented this template for both the store and edit blades. The event manager works in the store blade, but in the edit blade, it adds a month to the date in addition to the day.
That is, if I enter the value 6 in the deadline, the final date will be one month and 6 days.
I am surprised that the conditions are completely similar and I have copied the codes related to the edit blade from the store blade.
The values displayed in the console are exactly the same, except for the end date |

I have a ksqldbcluster with 2 nodes. Sometimes i might receive an alert from grafana(which i monitor the cluster) that some queries are in error state. When i check the show queries i see that a number of queries have 1 PERSISTENT running and 1 ERROR. I restart first the second ksqdb docker instance. Sometimes is fixed sometimes is not.

You should only add an epsilon transition from final states back to the start state.
You seem to have transitions from every state back to the start state. |
Termux does not (yet) appear to support recording directly to mp3 format. To get an mp3, you'll need to convert your recording using ffmpeg.
AWR Wide format has good quality for speech recording.
<!-- language: shell -->
# Begin recording
termux-microphone-record -e awr_wide -f filename.amr
# Stop recording
termux-microphone-record -q
# Convert to mp3
ffmpeg -i filename.amr filename.mp3

Here:
```
g++.exe -o bin\Release\GraphicsC++.exe obj\Release\main.o -s ..\..\..\..\Windows\SysWOW64\glu32.dll
```
You are trying to statically link a DLL (glu32.dll). You cannot do that, and your "simple code snippet" does not need OpenGL in any event.
Moreover you cannot normally statically link code built using a different incompatible toolchain. If you do need to link the OpenGL Utility library in your code, you should link the *MinGW provided* export library with the command line switch `-lglu32`. That will cause the _appropriate_ Windows provided DLL to be loaded at runtime.
You should not try to link a specific DLL path - and using a relative path is bound to fail at some time, it rather assumes that your project will always be in the same place relative to the DLL.
Linking the OpenGL Utility library on its own with no other OpenGL support probably won't be useful either - but that is a different issue. |
I'm re-doing a multi-page website I made with Dreamweaver over a decade ago for my Stained glass business. It is old code and I am a do it yourself amateur as a web-site maker, but the site pages look good on browsers, links work, text size ok, images and background graphic look good to me. **I'm trying to get one of the pages to center in browser windows** so I can do that with all pages. The site uses absolute position to arrange the photo images of windows and some text boxes. It uses a table for reference links to different gallery and information areas of the site. It uses the built-in Dreamweaver CSS text for style rules.
I followed a Dreamweaver tutorial on centering the page which basically goes like this:
\</head\>
**\<body\>**
**\<div id ="wrapper"\>**
\<. web page information/code/ html stuff\>
**\*\</div\>**
\</body\>
\</html\>
The CSS goes like this
\<style type="text/css"\>
\<!--
**#wrapper{**
**margin: 0 auto;**
**width: 1240px;**
**}**
This code looks pretty standard from my inquiries but it is not making the page center in a browser window; the page still hugs the left side. The Dreamweaver community forum, dominated by Nancy O'Shea refuses to help unless I learn the Bootstrap code, and I am not ready for that, having spent many, many hours cleaning up errors on current code and changing some style issues and adding new pages etc. I don't know what is causing the problem: absolute positioning?, the table?, my background graphic gif? If a helpful person knows why my attempt to center is failing It would mean a lot to me. If it would help I will post the entire block of code for the page.
