[Ilisp-help] Re: (Lisp Support Call #8020) LWW and Emacs ILISP

[Brigitte B. <bb...@ha...>]

Hi Chris,

Thank you for your detailed messages.

Developers can't repeat this and suspect it is a bad interaction with
emacs shell buffers.  If the message box has appeared, then the
process is inside Windows, and I don't see how LWW can affect it.

Some developers have seen similar problems when running Windowing
processes in the emacs shell buffer, but never with Console processes.
Note that Microsoft don't support creation of windows in Console
processes, so MessageBox() might not be expected to work anyway.

The machine we tested this on was running NT Workstation 4.0 SP6a and
we were using an identical emacs 20.7.1 build.


A couple more things to try:

1) Start the LW console image in a shell buffer and call MessageBox()
directly, rather than through the CAPI:

(win32:message-box 0 "BAR" "LispWorks Message" 73792)


2) If you have VC++, try making a C console executable that calls
MessageBox() with the args above:

cl mb.c /link /subsystem:console user32.lib

------------------------------------ mb.c ------------------------------------
#include <windows.h>

int main()
{
  return MessageBox(0, "BAR", "LispWorks Message", 73792);
}
------------------------------------------------------------------------------

See how this behaves in emacs (we can send this as a .exe if needed).


Cheers,
