[trioum]

I am using the two stage check box in sdk(not MFC). when i checked or unchecked on checkbox then how can I find out whether the checkedbox is checked or unchecked. I am using the following code. case WM_COMMAND: if(LOWORD(wParam) == IDC_CHECKBOX1) { }

For use it you must use of SendMessage with handle of your control.

case WM_COMMAND:
if(LOWORD(wParam) == IDC_CHECKBOX1)
{
LRESULT ret = ::SendMessage((HWND)lParam, BM_GETCHECK, 0, 0);

  if (BST\_CHECKED == ret)
  {
  }
  else if (BST\_INDETERMINATE == ret)
  {
  }
  else  // must be BST\_UNCHECKED
  {
  }

}
