Store name of MFC child form in string

[eddiemjm]

Newbie. I have a standard MFC application with which I can open .bmp files etc, on the top border the name of the file appears. How can I store the name of the current file that is open into a variable. Is it something to do with


#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif


TRIED THIS (DOESN'T WORK):
??????
CString currentFile;
currentFile = __FILE__;
??????


I want to store it in a variable so that I can use the name of file as a ID in a database.

Any help would be much appreciated...

When I assign

fileName = __FILE__;

OR

fileName = THIS_FILE;

I get a run time error in a dialog box saying "String data, right truncated"

????
