Hello It compiled after I removed a line that I had previously written.But
now the prob is it is not doing anything.On the gui i click the button and
the message should come right.It is not.

this is the part of the code in which commented out the prototype.I s that
correct to do? help me plz

void CSomethingDlg::OnBcreate()
{
//DWORD somethread(LPVOID lpvoid);//he prototype of the thread controlling
function
        AfxBeginThread((AFX_THREADPROC)somethread, this);//starting the thread
worker here

        

}
