I'm using a DLL written in C++ which creates a processing thread which processes items added to a queue from other threads. This works well from unmanaged code but I am now trying to use the DLL in a managed application. The thread is created and runs as expected processing items passed to it from C#, the problem occurs when I try to call Application.Run(dialog) or dialog.ShowDialog(). The form is destroyed immediately so it simply flashes on the screen and disappears. This does not happen when the unmanaged thread is not running.
The loop within the C++ thread is simply:
while( true )
{
WaitForSingleObject(hEvent);
while( !queue.empty() )
{
DoProcess(queue.front());
}
}
And the thread is created with:
g_hThread = CreateThread(NULL, NULL, ThumbnailThreadProc, NULL, 0, &g_nThreadId);
Is there a reason for this behaviour?

You dont need to prefix the function with 'javascript' if its already in a script block.
Even better head off to the ASP.NET forum, and ask them how to put that in the 'body loader' of the page.

Hi,
Iam a new to .net just begined few days back and iam facing difficulty in many things so only and posting things like that better u may give some idea regarding that

I don't believe being new in .NET is an excuse.
If you have searched your problem in CP, before you post your question, I am %100 sure that you would find your solution a lot more quicker than waiting for someone to post an answer.
Well anyway you have got your solution. What makes this argument unnecessary.
Happy coding.

You cant, and it is not even supported in Vista, so look for another solution.

Instead of using Allow service interact with desktop setting it is better to have a separate winforms application that will be used for interacting with users. To communicate with this application and service you can use various IPC techniques such as pipes and remoting.

I've been playing with VS2008 this week, creating a data access project with C#. All was going nicely until tonight. I built a few forms to act as containers for the basic functions of the app, with the idea in mind that I can launch a series of dialog boxes from each form to walk the user through the steps to perform each function. I have no idea how to do that yet, but I'll learn.
After creating all the basic forms I tried to Build the solution, and received this error:
Error 1 The item "obj\Debug\EquipmentData.frmRecord.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.
I have no idea where to go from here. The referenced file exists in the specified path. No resource file in the project refers to it twice. The error message tells me which project is causing the error, but doesn't include any mention of the file where the error appears. Online Help tells me that this can be caused by a duplicate entry in a resource file (there are none) or a command line, but I don't know how to view the command line used by the Build option in the IDE.
Can anyone tell me where to look to find the duplicate entry?

Hi guys,
If there is a textbox control in one form then how to assign it value to another form,for example to radio button (text) control.
|

Hi, i really dont have a clue of what you are trying to achieve there, but consider using other methods besides that.
Use mdi parent/child forms for exemple!!!  or create a single form and fill it with different pages(usercontrols).
Drop that method (if you really can use other) ok???

Is there a way to change the default node class type used by a TreeView control? I would like the TreeView to operate normally, but instead of creating TreeViewNode objects, to create MyTreeViewNode objects. I would like the node to expose an additional attribute.
class MyTreeViewNode: TreeViewNode
{
public string ExtendedProperty
{
get
{
}
}
}

If I remember correctly, the answer is NO.

You'll need to create your own MyTreeView that takes your TreeNode Type in place of the System.Windows.Forms one by creating the new properties and methods you need and hiding the old ones, as well as creating MyTreeNodeCollection etc...
Then you can just use your MyTreeview instead.

Hello everyone,
Does anybody know how I would go about creating a tab control that allows you to add a tab, and then add a NEW web browser control to that newely created tabpage, and then be able to perform actions on the webbrowser control in the currently selected tabpage (i.e. GoBack(), GoForward(), Stop(), Navigate..) and I also want to be able to display the title of the website on each tab?
I am having lots of trouble with this, have found zero help on Google, MSDN, and about 5 other search engines i've looked on. Does anybody have any sample code, tutorials, or advice that you could share as I am completely baffled  . I'd appreciate any kind of help at all from anybody, thanks in advance.
Regards,
j.t.
