How to start a macro from another program without starting the macro player by a command line switch?

The Macro Express Player (MACEXP.EXE) can be running already (i.e. it is in the taskbar) when you issue the command line parameter and it will run the macro. However, since the Macro Express Player is a good size, this can cause a noticeable delay. We have created a small executable to overcome this. The file is MEPROC.EXE. You can use either the /A or /MXE command syntax that is available with MACEXP.EXE. If the Macro Express Player is not running and you use MEPROC.EXE, it will first launch it and then run the macro; otherwise, it just sends some windows messages directly to the player.

If you want to try and simulate what MEPROC.EXE does, I can give you the basics:

Do a FindWindow on “Macro Express Player” to get the window handle.
For this example, the Window Handle is W.
N is the command and will be as follows:
N := wm_user+20 (for nickname)
N := wm_user+21 (for playable macro name)
S = the nickname or the playable macro name

CODE:
for K := 1 to length(S) do
PostMessage(W, N, ord(S[K]), 0);
PostMessage(W, N, 0, 0);
