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;
}

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);
}

Knock out 't' from can't, You can if you think you can :cool:
