I would like to know how to call a function from an already injected DLL.
So, I have successfully injected and loaded my DLL in the target using CreateRemoteThread(). Below you can see a snippet of the injection:
private static bool Inject(Process pToBeInjected, string sDllPath,out string sError, out IntPtr hwnd, out IntPtr hLibModule)
{
IntPtr zeroPtr = (IntPtr)0;
hLibModule = zeroPtr;
IntPtr hProcess = NativeUtils.OpenProcess(
(0x2 | 0x8 | 0x10 | 0x20 | 0x400), //create thread, query info, operation ,write, and read
1,
(uint)pToBeInjected.Id);
hwnd = hProcess;
IntPtr loadLibH = NativeUtils.GetProcAddress( NativeUtils.GetModuleHandle("kernel32.dll"),"LoadLibraryA");
IntPtr dllAddress = NativeUtils.VirtualAllocEx(
hProcess,
(IntPtr)null,
(IntPtr)sDllPath.Length, //520 bytes should be enough
(uint)NativeUtils.AllocationType.Commit |
(uint)NativeUtils.AllocationType.Reserve,
(uint)NativeUtils.MemoryProtection.ExecuteReadWrite);
byte[] bytes = CalcBytes(sDllPath);
IntPtr ipTmp = IntPtr.Zero;
NativeUtils.WriteProcessMemory(
hProcess,
dllAddress,
bytes,
(uint)bytes.Length,
out ipTmp);
IntPtr hThread = NativeUtils.CreateRemoteThread(
hProcess,
(IntPtr)null,
(IntPtr)0,
loadLibH, //handle to LoabLibrary function
dllAddress,//Address of the dll in remote process
0,
(IntPtr)null);
uint retV= NativeUtils.WaitForSingleObject(hThread, NativeUtils.INFINITE_WAIT);
bool exitR = NativeUtils.GetExitCodeThread(hThread, out hLibModule);
return true;
}
Note: Error checking and freeing resources were removed for brevity, but rest assured I check all the pointers and free my resources.
After the function above exits, I have a non-zero module handle to my DLL returned by LoadLibrary through `hLibModule`, meaning that the DLL was loaded correctly.
My DLL is a C# class library meant to show a message box (for testing). I have tried testing the function and the message box pops up. It looks like this:
public class Class1
{
public static void ThreadFunc(IntPtr param )
{
IntPtr libPtr = LoadLibrary("user32.dll");
MessageBox(IntPtr.Zero, "I'm ALIVE!!!!", "InjectedDll", 0);
}
[DllImport("kernel32", SetLastError = true)]
public static extern IntPtr LoadLibrary(string lpFileName);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern int MessageBox(IntPtr hWnd, String text, String caption, int options);
}
I compile it from Visual Studio and the DLL appears in the Debug folder. I then pass the full path of my DLL to the injector.
After injection into the target process, I don't know how to call my `ThreadFunc` from the injected DLL, so it never executes.
I cannot use `GetProcAddress(hLibModule,"ThreadFunc")` since I am out of process, so the answer must lie into calling CreateRemoteThread() somehow. Also, I have read that DllMain is no longer allowed for .NET DLLs, so I cannot get any free execution that way either.
Does anyone have any idea how to call a function from an injected DLL?

The motivations for this is
- Better ***control*** over ***alignment*** and in turn better performance for vector optimizations.
- Prevents us from having to ***unpack*** data-elements when interfacing low-level CPU-GPU data-transfer-operations (such as an array of vertices and colors) in OpenGL.
Iterators should construct and return a `boost::tuple<>` ***on-the-fly*** when dereferenced.
I'm aware that not all STL-member functions could be supported efficiently in this container. Still I believe it could be made very STL-like anyway.

I'm trying to make a program in C# that will allow C# code compiled by the program to act as a scripting language.
Here is my example code for the program that loads and compiles the code:

using System.Reflection;

if (results.Errors.Count > 0)
{

String ErrorText = "";
foreach (CompilerError CompErr in results.Errors)
{
ErrorText = ErrorText +
"Line number " + CompErr.Line +

I have a JAVA desktop application with shapes that can be drawn into a workspace, which can be connected by arrows:
[ Node1 ] ---------------> [Node2]
Besides, I have a desktop application which interprets the diagram nodes, each node is a screen, so I know that when you get (Next) to Node1, show the screen that represents the Node2.
What we now need is that each node has programming, this means for example that I say:
If Node2 receives an arrow of Node1, then increases and returns a variable x 3 (For instance)
What comes to mind is to make a programming language that is interpreted by java and assign a function to each node, so I would have the following function (defined in pseudolenguaje)
function f_node2() {
var++;
if (var == 3) {
return "OK";
} else {
return "BAD";
}
}
[ Nodo1 ] ---------------> [Nodo 2] (apply function "f_node2")
What I do not understand is if I have to develop a compiler entirely, if I have to develop an interpreter, if I can do this directly with Java or Groovy and then interpret that code with a tool, I saw something of ANTLR but do not wave :S
I feel a little lost, infinitely appreciate your guidance

In order prevent further complications down the road on an application I am building, I want to create an editable view, that shows the link records and an inverse copy of the link records.
Meaning if Joe is linked to Sally, then the view should show Joe linked to Sally and Sally linked to Joe.
So I have created a UNION as follows:
CREATE VIEW links AS
SELECT id,
link_origin_id AS person_id,
link_origin_id,
link_rcvd_id,
link_type,
link_summary,
created_at,
updated_at
FROM links_data
UNION
SELECT id,
link_rcvd_id,
link_origin_id,
link_rcvd_id,
link_type,
link_summary,
created_at,
updated_at
FROM links_data
The view works fine. Note that the view creates an additional column 'person_id' which is not in the underlying table.
I am running into trouble creating postgres rules that will edit the underlying table.
Specifically, I can successfully edit a table view when it is not a UNION view. But below is what occurs when I try to write a rule with a UNION view:
CREATE RULE inverse_links AS ON INSERT TO links DO INSTEAD
INSERT INTO links_data
(id, link_origin_id, link_type, link_summary, link_rcvd_id, created_at,
updated_at)
VALUES (nextval('people_id_seq'), new.link_origin_id, new.link_type,
new.link_summary, new.link_rcvd_id, new.created_at, new.updated_at)
RETURNING *;
The above rule should redirect the edits to the underlying table 'links_data'.
But I am getting the following error:
ERROR: RETURNING list's entry 3 has different type from column "link_origin_id"
********** Error **********
ERROR: RETURNING list's entry 3 has different type from column "link_origin_id"
SQL state: 42P17
The 2 things I feel might be the problem is that 1) the view has an additional column which is causing the column types to not match up or 2) there might be something with the fact that the table is a UNION on itself and editing this might be a problem.
Any idea of where I can go with this?

The 2 things I feel might be the problem is that 1) the view has an additional column which is causing the column types to not match up or 2) there might be something with the fact that the table is a UNION on itself and editing this might be a problem.
Any idea of where I can go with this?

I have a series of actions I want to perform on page unload. Namely if a user is editing an input field, and they refresh or close browser or leave page, I want to save the contents of the field.
The actions don't include an AJAX call, so I can't just make it synchronous. It's actually saving to local storage, but the page unloads before the storage can take place. The code is correct, if I add an alert to the actions, the delay allows the rest of the code to finish before it even displays.
Any ideas?
Thanks! | 0 |

We have two branches **master** and **release**, **master** contains some proprietary components that we have decided not to release, and **release** contains the cleaned-up version that we want to distribute. The problem is, if we just push the **release** branch to github, the proprietary components can be retrieved by looking through the revision history.
I was considering creating a separate repository, copying the HEAD of **relase** into it, doing a <code>git init</code>, and pushing that repository to github. However, we want to retain the ability to cherry-pick certain patches from **master** into **release** in the future, and push those changes up to github.
Is there a way to do this without maintaining two separte repositories?

When the `action` tries to save an entry into this `model` that already exists, i.e. 1 (user_id), 22 (group_id) already exists, at that time I want to raise a violation. What is the way to do this in rails?
Following is the code I am using to save right now:
if @department.save
flash[:notice] = "Successfully created department."
redirect_to @department
else
render :action => 'new'
end
`Department` model
class Department < ActiveRecord::Base
belongs_to :group
belongs_to :user
end

http://edndoc.esri.com/arcobjects/9.2/NET_Server_Doc/developer/samples/Web_Applications/ArcGIS_Buffer_Geoprocessing/ee05ac98-384b-4dbe-b8e3-8d741180dc9a.htm
I'm practically drawing a circle around a point with a geoprocessing service. The radius is about 20 km.
The code is working fine, but the "Clear" routine isn't. Every time I clear the map from the previous data, the memory of the buffer service isn't cleared too and I get this
![enter image description here][1]
The code of the "Clear" routine is the same of the sample, but isn't working:
// Clears features from all graphics layers in the resource specified by _graphicsResourceName
protected void ClearGraphics()
{
// Retrieve the resource and clear its graphics dataset
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource graphicsMapResource =
Map1.GetFunctionality(_graphicsResourceName).Resource as
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource;
graphicsMapResource.Graphics.Clear();
// This won't work too
GeoprocessingResourceManager1.GetResource(0).ClearState();
// Refresh the resource and copy the map's callback results to the callback results collection so
// the graphics are removed from the map
Map1.RefreshResource(graphicsMapResource.Name);
_callbackResultCollection.CopyFrom(Map1.CallbackResults);
}
This should be simple but I can't figure out how to solve this.. the only solution I found is to restart the IIS server which is obviously very bad
Can someone please help me out?
