m_INDEX_FILE.GetLength() <= 0

Hi ,
Instead of UpdateData() try using GetWindowText():
void CSearchDlg::OnSearch()
{
CString szCaption;
m_INDEX_FILE.GetWindowText(szCaption);
if (!szCaption.IsEmpty())
MessageBox("Select the Index File before searching !","Asis Search Engine",MB_OK | MB_ICONINFORMATION);
return;
}
Regards,
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;
}
UpdateData(FALSE);
}
Knock out 't' from can't,
You can if you think you can

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

Hi Friends,

Can anyone help me out fixing this problem.
Thanks in Advance.

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.

1) problem with your diff function. Solution cast the parameters to int or long, compiler seems to be confused between using one with int parameters or long parameters, since you call it with a mix (one param is int the other long).
2) the counter in your for loop has local scope in the for-loop alone now, so you need to redefine it
3) the -> must point to structure etc... Perhaps you need to cast... Did you define these as void pointers perhaps?

Hi,
I have 2 edit box in my dialog, word and selecting a file ..
first i have to enter the word then i have to select the file name
in the file name i have used the below code, once i select the file, text which i have entered in the word edit box is getting erased, is there any way that after selecting file text in the word edit box does not get erased ..
-----------------------------------------------------
void CSearchDlg::OnOpenIndex()
{
CString fname;
CFileDialog m_ldFile(TRUE);
if (m_ldFile.DoModal() == IDOK)
{
fname = m_ldFile.GetPathName();
m_INDEX_FILE=fname;
UpdateData(FALSE);
}
