You should change the proper image type icon (The application bar shows the 16x16 one).

I am new to multithreading and my application doesnot compile. It is a Dialog Based Applicationin MFC with only one ButtonCtrl

Here's the code

UINT ThreadFunc(LPVOID pParam)
{
MessageBox("Thread Started");
return 0;
}

void CAppDlg::OnButtonClkRunThread()
{
AfxBeginThread(ThreadFunc, this);
}

Where am I going wrong?

And what does the compiler say? Be specific.

To add to it,

Manmohan29 wrote:
UINT ThreadFunc(LPVOID pParam)
{
MessageBox("Thread Started"); //----> BAD idea!
return 0;
}

void CAppDlg::OnButtonClkRunThread()
{
AfxBeginThread(ThreadFunc, this);
}

Because if your main thread becomes busy into something, the newly spawned thread as well would block for displaying the message. This is because you are using a function (MessageBox from MFC) that would make use of the default message pump of your application.

In other words, if you add a Sleep(3000); after AfxBeginThread, the message from your thread would probably be displayed after this sleep period only!

I see you're just starting to learn, but threading has such "gotchas", that you'll learn along the way. Lesson learned today: It isn't a great idea to use something within a worker thread, that may in turn use the default message pump of the application (in a blocking fashion). Smile | :)

The thread function should be a global function (not a member function of any class), or it must be a static member function of any class. Try this instead:

in your header file:

static UINT CThreadDlg::ThreadFunc(LPVOID pParam);

in the source file:

/*static*/ UINT CThreadDlg::ThreadFunc(LPVOID pParam){
OutputDebugString(_T("*********** Entered thread function ***********\n"));
return false;
}

Watch the output window of your debugger to see the text printed from your thread.

This is not default behavior, so whatever code you've added for setting the cursor position within the edit control needs to be removed/changed.
