This answer is not correct. The double backslash is only neccessary if you use a literal string in your programming code. Here you just read the name entered in a listbox. I recoomend to use the source level debuger and place some breakpoints. You should always check following things: is the function actually called? Does the Listbox provide the correct handle? (I also recommend to handle LB_ERR so you see it if something is wrong)Do you get the correct string back from the listbox? Is your call to ShellExecute handled correctly? Does it give back an error message?
I really do not understand why you need to ask such a question in the forum. You reaaly should invest some time to learn how to use the source level debugger and how to read the documentation.

Well you have to grab the device context of the Console Application. Then use normal SDK paint functions to paint to this device context.

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);
}

Look up CFileFind.
A sample[^].
Or you can use
FindFirstFile --> Look up this in MSDN you will get two samples there.
FindNextFile
