Hi ,

Instead of UpdateData() try using GetWindowText():

void CSearchDlg::OnSearch() 
{
   CString szCaption;
   m_INDEX_FILE.GetWindowText(szCaption); // m_INDEX_FILE is your CEdit member
   if (!szCaption.IsEmpty())
      MessageBox("Select the Index File before searching !","Asis Search    Engine",MB_OK | MB_ICONINFORMATION);
   return;
}

Eli

Try the following Code.

void CSearchDlg::OnSearch()
{
	UpdateData(TRUE);
	if (m_INDEX_FILE.IsEmpty())
	{
		MessageBox("Select the Index File before searching !","Asis Search Engine",MB_OK | MB_ICONINFORMATION);
		return;
	}
	if (m_WORD.IsEmpty())
	{
		MessageBox("Enter the word to be searched","Asis Search Engine",MB_OK | MB_ICONINFORMATION);
		return;
	}
        //Do your stuff here
	UpdateData(FALSE);
}

Or you can use

FindFirstFile --> Look up this in MSDN you will get two samples there.

In most cases you don't have to worry about it - just like text buttons in Message boxes, this dialog depends on windows version. And users of your German version will use German windows, so they will see it in German. Still you can change the texts, but not with rc file - by using custom template extension for FileOpen dialog, and then directly iterating and translating controls on main dialog.
