[Dev-C++] EM_SETSEL message

[Noorez K. <lor...@ho...>]

I'm testing replacing text in an EDIT control. The tutorials that I read 
weren't very clear. Here is the test method:

void TEST(HWND main, HWND edit)
{
   int nLength = GetWindowTextLength(GetDlgItem(main, IDC_MAIN_EDIT));
   char* pszText = "BYE";
   SendMessage(edit, EM_SETSEL,     (WPARAM)nLength, (LPARAM)nLength);
   SendMessage(edit, EM_REPLACESEL, (WPARAM)FALSE,   (LPARAM)pszText);
}
