Platform: Windows xp compiler: vs2008
After application started, when i click the ui, Application hangs with 100% usage:
so i have tried to find which thread makes this hang and so i have freezed the main thread then application hangs stops. After investigating Main thread hangs most of the time on CallWindowProc method.
LRESULT CWnd::DefWindowProc(UINT nMsg, WPARAM wParam, LPARAM lParam)
{
if (m_pfnSuper != NULL)
return ::CallWindowProc(m_pfnSuper, m_hWnd, nMsg, wParam, lParam);
WNDPROC pfnWndProc;
if ((pfnWndProc = *GetSuperWndProcAddr()) == NULL)
return ::DefWindowProc(m_hWnd, nMsg, wParam, lParam);
else
return ::CallWindowProc(pfnWndProc, m_hWnd, nMsg, wParam, lParam);
}
please help me to sort out this issue.
