Hello

I have function wich I want to run in thead, the function looks like this:
void MainDlg::Recieve(LPVOID msg)
(it belongs to dialog class),
when I do:

HANDLE hThreadRecieve ;
hThreadRecieve = CreateThread(                        NULL,
            0,
            (LPTHREAD_START_ROUTINE)Recieve,                              (LPVOID)&msg,                        THREAD_QUERY_INFORMATION,                         &dwThreadID);

And then I have compiler error:
'type cast' : cannot convert from '' to 'unsigned long (__stdcall *)(void *)'

Why?
It workes in Console Application but not in MFC

Thanks

Your receive function must have this type declartion:
DWORD WINAPI ThreadProc(  LPVOID lpParameter   // thread data);

Change it to static and add WINAPI.

Hi,

Declare Ur thread function in dlg.h as a public as

static UINT Receive(LPVOID pParam );

Then write the function as
UINT ..Dlg::Receive(LPVOID s)
{
....
....
}

Then while spawning use
LPVOID s;
AfxBeginThread(Receive, s);

Try it out.
