Multithreading

Remarks#

MFC supports worker threads and gui threads (threads with message loops). See https://msdn.microsoft.com/en-us/library/975t8ks0.aspx for more documentation.

Simple AfxBeginThread Worker Thread Example

This example shows a call of AfxBeginThread that starts the worker thread and an example worker thread procedure for that thread.

// example simple thread procedure.
UINT __cdecl threadProc(LPVOID rawInput)
{
    // convert it to the correct data type. It's common to pass entire structures this way.
    int* input = (int*)rawInput;
    // TODO: Add your worker code...
    MessageBox(0,"Inside thread!",0,0);
    // avoid memory leak.
    delete input;
    return 0;
}
// ...
// somewhere that gets called when you want to start the thread...
int* input = new int;
*input = 9001;
AfxBeginThread(threadProc, input);
// after this, the message box should appear, and the rest of your code should continue 
// running.
