Currently, we are using a .net WebBrowser control to embed browser behavior in a winform.
We are attaching WatiN to the WebBroswer control on the form with code like this ( thanks prostynick ):
var thread = new Thread(() =>
{
Settings.AutoStartDialogWatcher = false;
var ie = new IE(webBrowser1.ActiveXInstance);
ie.GoTo("http://www.google.com");
});
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
The problem is this - the "winform browser" needs to handle popups during testing/automation.
Question: How can popups be handled when Watin is attached to a winforms webBrowser control ( and not using its own WatiN-generated IE window )?
a) Can Watin's DialogWatcher still be used? If so ...how?
b) If not, then perhaps we can write our own DialogWatcher -- but we would need an hWnd or processID to add it. Where would we get correct hWnd or processId in this scenario where Waitin does not have its own window or process?
Thanks in advance for any ideas ...alternate approaches that reach the same target are welcome!

After reading blog posts, the samples, the docs, etc. I cannot figure out why my C# class library will not send messages. on Bus.Send(msg) I get "No destination specified for message Messages.TraceStatement. Message cannot be sent. Check the UnicastBusConfig section in your config file and ensure that a MessageEndpointMapping exists for the message type."
But first, a little about my architecture and what I'm trying to do, as it differs from any of the samples I've seen out there.
My intent is to use SignalR and NServiceBus [like Ben did][1], but with two main changes:
1. No use of NServiceBus.Host.exe. I want a Web-only, no console implementation.
2. Messages are sent from a middle tier class library for the purpose of real-time code tracing. In other words, I want to sprinkle Bus.Send statements around my code and thereby be able to view code execution trace statements (which are just ad hoc strings set by the developer) on a Web page.
Assuming I haven't misunderstood NServiceBus to such a degree that what I envision is not even possible (or a misuse of the technology), I would like to figure out how to send messages from a class library. Currently I have a "Managers" dll that has an app.config file as follows:
<configuration>
<configSections>
<section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core" />
<section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core" />
</configSections>
<MsmqTransportConfig InputQueue="TerminalQueue" ErrorQueue="TerminalErrorQueue" NumberOfWorkerThreads="1" MaxRetries="5"/>
<UnicastBusConfig>
<MessageEndpointMappings>
<add Messages="Messages" Endpoint="WorkerQueue" />
</MessageEndpointMappings>
</UnicastBusConfig>
</configuration>
Note: In Ben's project I renamed "Commands" to "Messages". Thus (referring to the error message at the top of my post), as far as I can tell I have properly defined a MessageEndpointMapping. (I verified that the queue exists in MSMQ.)
Can anyone tell me what I'm doing wrong?
Also, I would greatly appreciate input on how to remove the NServiceBus.Host.exe dependency (refer to the Worker project in Ben's sample). Ideally the class library would send the message (like the Terminal did in Ben's project) and the Web app would, as a subscriber, be able to handle the event and use SignalR to display the message.

I need to validate the presence of each of these attributes which is obviously easy using
validates :attribute1, :presence => true
However I also need to run a custom validator which takes a number of the attributes and does some calculations with them. If the result of these calculations is not within a certain range then the model should be declared invalid.
On it's own, this too is easy
validate :calculations_ok?
def calculations_ok?
errors[:base] << "Not within required range" unless within_required_range?
end
def within_required_range?
# check the calculations and return true or false here
end
However the problem is that the method "validate" always gets run before the method "validates". This means that if the user leaves one of the required fields blank, rails throws an error when it tries to do a calculation with a blank attribute.
So how can I check the presence of all the required attributes first? | ruby-on-rails | ruby-on-rails-3 | validation | activemodel | null | null | open | Controlling the order of rails validations

However I also need to run a custom validator which takes a number of the attributes and does some calculations with them. If the result of these calculations is not within a certain range then the model should be declared invalid.
On it's own, this too is easy
validate :calculations_ok?
def calculations_ok?
errors[:base] << "Not within required range" unless within_required_range?
end
def within_required_range?
# check the calculations and return true or false here
end
However the problem is that the method "validate" always gets run before the method "validates". This means that if the user leaves one of the required fields blank, rails throws an error when it tries to do a calculation with a blank attribute.
So how can I check the presence of all the required attributes first? | 0 |

I subclassed a UIView, made it full screen and the highest view in the hierarchy, and overrode its pointInside:withEvent method.

If I return NO, the touch passes through the view and the buttons respond, but I'm not able to track touches.
Do I need to subclass UIButton or is this possible through the responder chain? What am I doing wrong?

One area of improvement that we found we could make with this function was to cache the responses from the web service for some period of time, since the data is not changing.
After implementing this basic caching, in some further testing I found out that I didn't consider how concurrent threads could access the Cache at the same time. I found that within the matter of ~100ms, about 50 threads were trying to fetch the object from the Cache, finding that it had expired, hitting the web service to fetch the data, and then putting the object back in the cache.
The original code looked something like this:
private SomeData[] getSomeDataByEmail(WebServiceInterface service, String email) {
final String key = "Data-" + email;
SomeData[] data = (SomeData[]) StaticCache.get(key);
if (data == null) {
data = service.getSomeDataForEmail(email);
StaticCache.set(key, data, CACHE_TIME);
}
else {
logger.debug("getSomeDataForEmail: using cached object");
}
return data;
}
So, to make sure that only one thread was calling the web service when the object at `key` expired, I thought I needed to synchronize the Cache get/set operation, and it seemed like using the cache key would be a good candidate for an object to synchronize on (this way, calls to this method for email b@b.com would not be blocked by method calls to a@a.com).
I updated the method to look like this:
private SomeData[] getSomeDataByEmail(WebServiceInterface service, String email) {
SomeData[] data = null;
final String key = "Data-" + email;
synchronized(key) {
data =(SomeData[]) StaticCache.get(key);
if (data == null) {
data = service.getSomeDataForEmail(email);
StaticCache.set(key, data, CACHE_TIME);
}
else {
logger.debug("getSomeDataForEmail: using cached object");
}
}
return data;
}
I also added logging lines for things like "before synchronization block", "inside synchronization block", "about to leave synchronization block", and "after synchronization block", so I could determine if I was effectively synchronizing the get/set operation.
However it doesn't seem like this has worked. My test logs have output like:
>(log output is 'threadname' 'logger name' 'message')

I wanted to see only one thread at a time entering/exiting the synchronization block around the get/set operations.
Is there an issue in synchronizing on String objects? I thought the cache-key would be a good choice as it is unique to the operation, and even though the `final String key` is declared within the method, I was thinking that each thread would be getting a reference to *the same object* and therefore would synchronization on this single object.
What am I doing wrong here?

The war will be using some property file defined under tomcat/bin directory and this property value is different for these two servers .
These two servers (Server A and Server B ) have different IP's .
Please let me know if Load Balancing will be any issue in this case ??

I was starting off the program and I wrote a header file with all my #includes and had the source code in another file. I accidentally had the #includes in both the header file and the source code and when I tried to compile, it started giving me all these errors saying (for example):

Keep in mind, this program was <200 characters at this point, so something was causing the compiler to write all these characters to the file.

By the time I canceled the compiler (it looked like it was going to just keep going), the file had grown from a couple of hundred bytes to nearly 13 MB in just a few seconds. I'm no expert but it seems like this kind of thing could have security implications, especially since I was running this program over ssh on my university's CS department server.

No reorganizing of the layout, resizing, orientationchange behavior.
I want it so that you rotate the phone and the initial layout loaded will stay the same, forcing the user into using the app in the original orientation. There are many subtleties to user logic and I truly feel this is needed in my app, so please no comments on that choice, rather help for my question in the first sentence.
1. I tried listening for BOTH 'orientationchange' and 'resize' events and calling preventDefault and stopPropagation on them, to prevent any browser behavior of reorganizing the page to fit a landscape view when turned. Well, obviously preventing ANYTHING (ideally). Made absolutely no difference. Browser still reorganized the page on Android (both pre2.1 and after) and iPhone 4-5.
2. tried meta tags
<meta name="viewport" content="initial-scale=1.0, user-scalable=no />
then got pissed, tried
<meta name="viewport" content="initial-scale=1.0, user-scalable=no, width=device-width" />
neither made a difference.
3. looked furiously on StackOverflow, saw what I did in step 1. put out there several times...tried again to make sure I wasn't messing something up. Didn't work.
4. sucked in my pride, then decided to keep running into a brick wall due to pride, then really sucked in my pride and posted here.

I am just started learning Hibernate and trying to create a first hibernate project.
I am using postgreSQL and doing everything as it is said in the first 3 tutorials (http://javabrains.koushik.org/p/hibernate.html)
But I have a very strange error. Can anybody explain how it is possible to solve this problem?

Most jobs tend to be looking for senior developers with a very precise skill set.

**Execution time** being the main point, since this is what I'm using to *benchmark* my piece of code.
<br>
My question is:
Is there a better (i. e. more reliable) way of benchmarking a program than just time the execution? It kinda works, but the same program (with the same background processes running) usually has slightly different execution times if run twice.
This kinda defeats the purpose of detecting small improvements. And several small improvements could add up to a big one...

I load a bmp file to a DC using LoadImage, and it shows up properly. However, when I call DeleteObject, the memory doesn't seem to be freed. (I use windows task manager to track the memory usage)
In the WM_INITDIALOG part I do this:
static HBITMAP hBitmap = 0;
char* tempPath = "tabView.bmp";
hBitmap = (HBITMAP)LoadImage(NULL,
tempPath, // file containing bitmap
IMAGE_BITMAP, // type = bitmap
0, 0, // original size
LR_LOADFROMFILE); // get image from a file
if(hBitmap)
{
SendMessage(GetDlgItem(hwndDlg, IDC_PICTURE),
STM_SETIMAGE, // message to send
(WPARAM)IMAGE_BITMAP, // bitmap type
(LPARAM)hBitmap); // bitmap handle
}
So the picture shows up in the DC, and memory increases. And in a button I do:
int result = DeleteObject(hBitmap);
When I press the button, I checked the result and it's a non-zero value, which is success. But IDC_PICTURE will still show the picture, and memory stays the same. I am wondering if the SendMessage() may increase the ref count on the hBitmap...
So my question is: What is the proper way to clean up?

I wont go into complexities, but it is designed to return text if it is a single request or a curl handle is appended if a multi_curl handle is passed.
The issue is, when I request it to do a task on a remote server, it does a double request. We have a setup where the requesting server is connected to remote server via VPN and can do a requests to external Internet through it. I thought the target server was running it twice so I made a call (for doing an email) from the calling server as follows: -
$aEmail = array("email_address" => $sEmailAddress, "email_subject" => $sEmailSubject, "email_body" => $sEmailBody);
echo sendPOSTtoURL("<REMOTE IP HERE", "/emailService/doMail.php?rand=".mt_rand(), $aEmail);
the call to mt_rand generates a random number so I can identify each request. This is what I got at the remote server: -
<CALLING IP> - - [15/Jun/2011:20:39:57 +0500] "POST /emailService/doMail.php?rand=1551627310 HTTP/1.1" 200 1060 "-" "-"
<CALLING IP> - - [15/Jun/2011:20:40:01 +0500] "POST /emailService/doMail.php?rand=1551627310 HTTP/1.1" 200 1060 "-" "-"
As you can see, the same request came in twice. and what do you think happens? right, 2 emails to the target! I cant (due to managerial [S@#$] reasons) develop logic to handle this on the Remote server.

I wont go into complexities, but it is designed to return text if it is a single request or a curl handle is appended if a multi_curl handle is passed.
The issue is, when I request it to do a task on a remote server, it does a double request. We have a setup where the requesting server is connected to remote server via VPN and can do a requests to external Internet through it. I thought the target server was running it twice so I made a call (for doing an email) from the calling server as follows: -
$aEmail = array("email_address" => $sEmailAddress, "email_subject" => $sEmailSubject, "email_body" => $sEmailBody);
echo sendPOSTtoURL("<REMOTE IP HERE", "/emailService/doMail.php?rand=".mt_rand(), $aEmail);
the call to mt_rand generates a random number so I can identify each request. This is what I got at the remote server: -
<CALLING IP> - - [15/Jun/2011:20:39:57 +0500] "POST /emailService/doMail.php?rand=1551627310 HTTP/1.1" 200 1060 "-" "-"
<CALLING IP> - - [15/Jun/2011:20:40:01 +0500] "POST /emailService/doMail.php?rand=1551627310 HTTP/1.1" 200 1060 "-" "-"
As you can see, the same request came in twice. and what do you think happens? right, 2 emails to the target! I cant (due to managerial [S@#$] reasons) develop logic to handle this on the Remote server.
Can ANYONE HELP? Pretty please with sugar lumps and cherries and strawberries on top...! | 1 |

routeData.Values.TryGetValue("name", out value);
Everything fine so far, I'm getting the proper values for each route. My problem is encoding: I want to get the **raw** value of a route data. Example: for the route above, if the requested URL is http://example.com/products/word%2Dword the resulted "name" is "**word-word**". What I want though is the exact value "**word%2Dword**".
I know that with ASP.NET I can get the row unprocessed URL using Request.ServerVariables["HTTP_URL"] but unfortunately I cannot use this here.
Any help would be appreciated.

I'm writing a C# (.net version 4) program to monitor a process. It already raises an event when the process starts and when it stops, but I also need to check where is this process reading from and writing to; specially writing to since I know this process writes a large amount of data every time it runs. We process batches of data, and the path where the process writes to contains the Batch ID, which is an important piece of information to log the results of the process.
I've looked into the System.Diagnostics.Process.BeginOutputReadLine method, but since the documentation says that StandardOutput must be redirected, I'm not sure if this can be done on a process that is currently running, or if it affects the write operation originally intended by the process.
It is a console application in C#. If anyone have any idea on how to do this, it would be much appreciated.
Thanks in advance!

The question is what its realy does ?
I know there is a comments, but you can explain or give me a tutorial for more of this ?
And we can switch it with ASM code ? How .. ?
Tnx guys ..

//
// Description:
// This function will inject a DLL into a process and execute an exported function
// from the DLL to "initialize" it. The function should be in the format shown below,
// not parameters and no return type. Do not forget to prefix extern "C" if you are in C++

// The function that is called in the injected DLL
// -MUST- return, the loader waits for the thread to terminate before removing the

HttpClient client = new HttpClient();
Boom! *System.Security.VerificationException: Operation could destabilize the runtime.*
I verified this on 2 machines, and then asked a friend to try it on his. He could not reproduce the error. After disabling all my VS2010 extensions, I realized TypeMock Isolator was still running. Disabling it fixed this issue.
Unfortunately, I don't have access to a newer version of Isolator, but I do know this happens on v6.0.3. I'll also add that I did not test this prior to installing MVC 4 beta, so it's possible the issue existed prior to this.
Hope this saves someone else some time. | asp.net-mvc-4 | typemock-isolator | verificationexception | null | null | 02/23/2012 20:42:40 | not a real question | FYI: ASP.NET MVC 4 beta and TypeMock Isolator 6.0.3 don't play nicely

The database is PostgreSQL 8.3.0 and the connection I use for creating the initial report is an ODBC connection.
I have found various ways to change the database connection including the following:
reportDoc.Load(report);
reportDoc.DataSourceConnections[0].SetConnection("server", "database", "user", "pwd");
reportDoc.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, path);
However, this always fails with the following error message.
> Failed to open the connection.
I have validated the connection parameters by successfully connecting to the database with pgAdmin III so I know the connection parameters are correct. In addition, if I remove the SetConnection(...) line so the code looks like this:
reportDoc.Load(report);
reportDoc.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, path);
then the report runs fine using the connection parameters that are stored in the report. Is it possible that this method does not work for ODBC connections?

fu! Create_file_and_write_to_it(name, text)

execute "w! " + a:name
endfu
I call this function like so:
:call Create_file_and_write_to_it('c:\temp\foo.txt', "here is some text")
While it creates a new buffer and writes the desired text (ie: *here is some text*) into the buffer, it doesn't write the buffer to a file named *c:\temp\foo.txt* or any other name I could see. Neither do I get an error message.
Is there a reason for this behaviour, or am I doing something wrong, and how would I go about getting the desired functionality?
