Hi guys.

I am writing an open source application for HAM radio operators. It is
a chat program over short waves. It uses speaker/mic to connect to the
outside world. http://pocketdigi.sourceforge.net

The call SHCreateMenu fails on only one device of about 200. It is IPAQ
3635 with windows 3.0, which I do not have access to. Other programs
run on his device flawlessly. I am testing the application it on
emulator and on IPAQ 3630, everything works.

I read huge lists of discussion on SHCreateMenu. It is mostly the
resource issue. It shall not be the case because it runs on number of
devices correctly.

I tried to call the SHCreateMenu with/without the SHCMBF_HMENU, none
works. Even the call with the flag SHCMBF_EMPTYBAR fails on his device.
On the other side, the deprecated APIs CommandBar_Create and
CommandBar_InsertMenubar work. I am clueless. Any help? I use the
eMbedded studio 3.0.

See the code. On the damned device the first two blocks fail.

Thanks, Vojtech

I can't help much, but do have a few comments.

The 3635 is one of the original Pocket PCs, based on version 3.0 of
the Windows CE operating system. SHCreateMenuBar definitely works on
my 3600, and sure should work on your 3630 (I assume you mean
SHCreateMenuBar, rather than SHCreateMenu).

I sure haven't been able to use SHCreateMenuBar without a SHMENUBAR
resource in my resource script (.rc file). Possibly relevant: 20-24
Feb 04 called "SHCreateMenuBar() without a resource file" in
microsoft.public.pocketpc.developer. In particular, see 20 Feb 04
contribution from Almond Stowger for ideas. Also, a 19 Feb 04
contribution from Eddy Escardo says:
SHCreateMenuBar does not currently support programatically
generated HMENUs, as the SHCMBF_HMENU flag just means that
nToolBarId will represent the ID of a menu in a compiled
resource module, not an actual HMENU that you can pass to
the SHCreateMenuBar call (as you've probably figured out by now).

I think I've had serious problems with SHCMBF_EMPTYBAR. Comments in my
code reference a 13 Nov 04 contribution from Almon B. Strowger to
thread called "SHCreateMenuBar" in microsoft.public.pocketpc.developer

CommandBar_Create forces an application to run in "emulation mode",
with Task Bar on the screen bottom and application menu on the screen
top. It seems to work on all Pocket PCs except Pocket PC 2003. But I
no longer trust it for Pocket PCs

Is this hWnd for the main window?

Is this defined in a resource script (.rc file)?

I use the following to get the HMENU for the main menu:
m_hMenu = reinterpret_cast<HMENU>(::SendMessage(
s_hWndCommandBar, SHCMBM_GETMENU, 0, 0 ));

and then use the following (edited a bit) to get other HMENUs:

}

#endif

return hMenu;
