Hi,
either by using enum or by # define e.g.

enum
{
WM_DOCLISTDCLICKED = WM_APP+1,
WM_DOCLISTCLICKED = WM_APP+2
};

OR
# define WM_DOCLISTDCLICKED WM_APP+1
# define WM_DOCLISTCLICKED WM_APP+2

Owner Draw Menu[BCMenu] cant change the text color of menuitem on menuBar

2-Jan-09 2:36

Well, i was just curious that whether you was using the obsolete WM_USER for defining you messages. The ON_MESSAGE is changed in VS 2005[^]. Well, could you please post your message map and relevant code snippet?

Regards,
Jijo.

Has anyone of u used this article owner draw menu?

If anyone used it and know how to solve my problem, Please help - Highly Appreciated

http://www.codeproject.com/KB/menus/bcmenu.aspx

Hi, when i tried this owner draw menu, why did the DrawItem function are not being triggered??
Because when i tried other owner draw menu, even if i did not click the menu item[on the menu bar] it will trigger the DrawItem.

I'm trying to change the font's color of the menu item text[on the menu bar]
I already succeeded to change the font color of the submenu items.. which it will trigger DrawItem function when i click it.

Thanks,
KH

open both files using ifstream

use strcmp or wcscmp to compare.

BTW the posted code is computing the checksum of the array content. Roll eyes | :rolleyes:

From the MSDN:

&& (and)

&= (and_eq)

& (bitand)

| (bitor)

~ (compl)

! (not)

!= (not_eq)

|| (or)

|= (or_eq)

^ (xor)

^= (xor_eq)

You can use of this code on the paint event or earse event(I didnt test but I think it works).
#include "Atlimage.h"
CImage m;
m.Load(_T("c:\\1.jpg"));
m.BitBlt(0,0,800,600);

Check out this article - Displaying a Bitmap from a BMP File[^]. If you don't want to display the file, then just skip that part and refer the drawing part only.

Array size must be specified!

You can quickly check in the debugger to find out!
