Hi.

I'm facing a problem with my MDI editor: I can't use accelerators. I used a resource editor (and compiled the result with GoRC) to prepare an options dialog, to add icons and now I want to add some shortcuts for the user. Ctrl+X/C/V are already recognized by the RichEdit control, so I simply need to show them in the menu, but I need to add one to open and save a document, one to create a new one and other two to compile the file edited by the user.
Here is the part of the resource file created with the editor:

Code:

IDR_ACCEL ACCELERATORS
BEGIN
  78,IDM_NEW,VIRTKEY,CONTROL,NOINVERT
  79,IDM_OPEN,VIRTKEY,CONTROL,NOINVERT
  83,IDM_SAVE,VIRTKEY,CONTROL,NOINVERT
END

, and here is the message loop I use:

Code:

  msg_loop:
 invoke  GetMessage,msg,NULL,0,0
     or      eax,eax
     jz      end_loop
        invoke  TranslateMDISysAccel,[hwnd_client],msg
        .if eax = 0
            invoke      TranslateAccelerator,[hwnd_client],[hAccel],msg
            .if eax = 0
                invoke       TranslateMessage,msg
                invoke  DispatchMessage,msg
            .endif
        .endif
 jmp     msg_loop

Of course I loaded the accelerator table with

Code:

invoke  LoadAccelerators,[hinstance],IDR_ACCEL
mov     [hAccel],eax

I tried also to connect the accelerator to [hwnd_frame] instead of [hwnd_client], even it should not be so, but no way.
Any tip? Thx in advance!

Is the handle, returned by LoadAccelerators ok? Check eax for 0 (function failed) before saving the handle to memory.

I tried, it seems to be ok. I enclose a zip file with the program until now.

Why not use hwnd_frame handle instead of hwnd_client?

Code:

            invoke      TranslateAccelerator,[hwnd_frame],[hAccel],msg

Second, instead of comparing whole wparam with the ID, only compare the lowerword of wparam!

Code:

        cmp     word[wparam],IDM_NEW
        je      .fm_new

Thx pete! Now it works perfectly! I've tried using [hwnd_frame], but without result. I supposed that just comparing wparam was enough, I didn't imagine that comparing the whole wparam was the origin of the problem... Now I added also the other accelerators I need for the moment. Thanks, really thanks!

Make use of dbmon.exe and OutputDebugString Function; these help you when debugging your applications!
