                                         ^^^^^^^^ Should be FILETIME

Under Microsoft C (5.1), just do:
		
		SetDlgItemText (hDlg, ID_FILEDATE, (LPSTR)__DATE__);
		SetDlgItemText (hDlg, ID_FILETIME, (LPSTR)__TIME__);

This will give the time of the compile.  This much more useful
(and more reliable) than the date of the EXE.  This is also not
dependent on the finding location of the program.  (as Tom said,
the code depends on the EXE being in the current directory; not
really a good limitation) The __xxx__ are defined by the C compiler.  

Other useful items are __LINE__ and __FILE__ which give the current 
source line and file.  (useful in doing Asserts ).

These are documented somewhere.  (I know that they are mentioned
on page 31 of the Quick Ref Guide.)

Ya, me too.  A good rule of thumb is if "strange things are happening"
then you forgot to export the function.
