Unhandled Exception

[aaadetos]

Hi, I have a dialog-based MFC application, which compiles w/out error, but yields an unhandled exception in C:\...\MFC\SRC\WINCORE.CPP when i try to run it, as shown in the code below. What could be the reason for this? How do i correct it?

		HWND hWnd = ::GetDlgItem(m_hWnd, nID);
		if (hWnd != NULL)
		{
			int nLen = ::GetWindowTextLength(hWnd);
			::GetWindowText(hWnd, rString.GetBufferSetLength(nLen), nLen+1);//exception here
			rString.ReleaseBuffer();
		}

It could be a lot of things. What are you passing to SetWindowText?

This would definately throw something:

CString* s=0;
SetWindowText(*s);
