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

Thanks for your reply.But if I run this example on my pc it retrieves the drives of my pc.Suppose I want to retreive the drives of a pc having name for eg. abc which is connected through LAN to my pc. Please tell me the first parameter of NetServerDiskEnum .

Regards,
Abinash

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?

Usually compiler errors are pretty informative, so have a look at it.
I guess the error occurs in

try this ...

UINT ThreadFunc (LPVOID lpParam)
{
	::MessageBox(0,L"Thread Started",L"",1);
	return 0;
}

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

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 member has to be declared as 'static'.
