	Mike Morris sez:
>I want the About item to bring up a window which has ... "<application name>"
>Version NN.NN, dated MM/DD/YY, at HH:MM"

Here's what I did: In AboutDlgProc, which is the proc for the About... box put

BOOL FAR PASCAL AboutDlgProc (hDlg, message, wParam, lParam)
HWND	hDlg;
unsigned message;
WORD	wParam;
LONG	lParam;
{

struct stat stFileInfo;
struct tm *npstFileTime;
char   *szAmPm;
char   *szTemp [81];

switch (message)
	{
	case WM_INITDIALOG:
		stat ("vers.exe", &stFileInfo);
		npstFileTime = localtime (&stFileInfo.st_atime);
		if (npstFileTime->tm_hour < 12)
			szAmPm = "am";
		else
			szAmPm = "pm";
		if (npstFileTime->tm_hour > 12)
			npstFileTime->tm_hour -= 12;
		if (npstFileTime->tm_hour < 1)
			npstFileTime->tm_hour = 12;
		sprintf (szTemp, "%2d/%02d/%02d", npstFileTime->tm_mon + 1,
				npstFileTime->tm_mday, npstFileTime->tm_year);
		SetDlgItemText (hDlg, ID_FILEDATE, (LPSTR)szTemp);
		sprintf (szTemp, "%2d:%02d%2s", npstFileTime->tm_hour,
						npstFileTime->tm_min,
						szAmPm);
		SetDlgItemText (hDlg, ID_FILEDATE, (LPSTR)szTemp);
		return FALSE;
		.
		.
		.
		(rest of dialog box code)
	}
}

Don't forget to export AboutDlgProc in the .DEF file. (I always do)
vers.exe is the name of the program and will have a system date & time of the
latest compile. No path is specified here, so stat will look in the current working
directory. Experiment to see if there may be a problem with this. Use the name of 
your program in place here. stat and localtime are standard C library functions. 
For the declarations of these and the typedefs put these includes at the top of 
your program

#include <stdlib.h>
#include <time.h>
#include <dos.h>
#include <\include\sys\types.h>
#include <\include\sys\stat.h>

Note the use of the nefarious sprintf function. You may want to do it right
and use simpler library functions, the undocumented windows long pointer
string functions, or the recommended method of making your own long pointer
functions with the assembler.


The dialog box template in the .RC file contains


ABOUTBOX DIALOG 60, 30, 117, 110
STYLE WS_DLGFRAME | WS_POPUP
BEGIN
	CONTROL "Vers version 1.00", -1, "static", SS_CENTER | WS_CHILD,
							15, 11, 80, 8
	CONTROL "File date:", -1, "static", SS_CENTER | WS_CHILD,
							12, 27, 48, 10
	CONTROL "File time:", -1, "static", SS_CENTER | WS_CHILD,
							13, 42, 46, 10
	CONTROL "", ID_FILEDATE, "static", SS_LEFT | WS_CHILD,
							64, 27, 37, 12
	CONTROL "", ID_FILETIME, "static", SS_LEFT | WS_CHILD,
							64, 42, 37, 12
	CONTROL "Ok", ID_OK, "button", BS_DEFPUSHBUTTON | WS_TABSTOP 
					WS_CHILD        39, 67, 41, 23
	.
	.
	.
	(rest of template)
END


Note the two controls identified by ID_FILEDATE and ID_FILETIME. Unlike other
controls of the static class, these will need unique identifiers because you
will be writing text to them with the SetDlgItemText function. The values
assigned to these will be up to you and will be in your program's header file.

Hope this helps.                     Tom Gimpel
