I've tried to make the program spy on WM_MENUSELECT,
but it won't seem to work.........
anybody have an idea ?

Maybe you should include the code for it ?
ps: Use Code Tags for code :)
.IF uMsg == WM_MENUSELECT
INT 3
.endif

Hi JimmyClif
Of course I did put in the code, but it didn't seem to work.
I wrote it like this:
.IF uMsg==WM_MENUSELECT
invoke MessageBox,NULL,ADDR lpText4,ADDR lpCaption4,MB_OK
.ENDIF
:)

The WM_MENUSELECT message is sent to a menu's owner window when the user selects a menu item.
But your window has no menu! You have to create it first.

Ups, I forgot to include the .rc file, so here it is
attached.
attached.
The branch:
Move it before DefWindowProc branch:
.IF uMsg==WM_MENUSELECT
invoke MessageBox,NULL,ADDR lpText4,ADDR lpCaption4,MB_OK
.ENDIFMove it before DefWindowProc branch:
.ELSEIF uMsg==WM_MENUSELECT
invoke MessageBox,NULL,ADDR lpText4,ADDR lpCaption4,MB_OK
.ELSE
invoke DefWindowProc,hWnd,uMsg,wParam,lParam
ret
.ENDIFHi Four-F, yes that works, BUT then the menu won't show.....:confused:
...BUT then the menu won't show...
Whet MessageBox gets displayed it grabs focus and this breaks normal processing of WM_MENUSELECT message. Don't use MessageBox for this.
Take a look at this utility:
VKDEBUG v1.1 released
It ideally does you want.
Download it, install and then compile code in attach. And have fun!
Hi Four-F
Yeah, that looks nice, but Spy++ does the job too....
How can it be created in MY program, so it WILL spy
on WM_MENUSELECT ?
If I can't make it display a MessageBox, what can be
done then....?

Spy++ is quite different story. It installs hooks and every message passing to hooked window procedure goes to spy first.
It collects messages and displays that info.

Display it id Edit control like vkdebug.
I don't understand why you want to spy message handling of your own window,
but take a look at this (c-source code):
Control Spy
There is nothing about menu spying there, but you can simply adapt source to your need.
Perhaps if you call DefWindowProc after you show the messagebox, the menu would still show. It seems logical, if the menu is opened by windows in DefWindowProc.
