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

use strcmp or wcscmp to compare.

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.

You can quickly check in the debugger to find out!

DWORD GetMessagePos(void);
This function returns a long value that gives the cursor position in screen coordinates.

How to get X and y coordinates.

Re: doubt in GetMessagePos() function

Nibu babu thomas1-Jan-09 20:19

Nibu babu thomas

1-Jan-09 20:19

Use GET_X_LPARAM and GET_Y_LPARAM.

// An eg:
const DWORD Pos = GetMessagePos();
const short XPos = GET_X_LPARAM(Pos);
const short YPos = GET_Y_LPARAM(Pos);

Another alternative is to use MAKEPOINTS structure, depends on if you want your pos wrapped in a POINT struct.
