I am trying to automatically press a button in a skinnable application using postmessage. I have used Winspector Spy to capture messages related to this button press. Unforunately, the main message for this action is a "registered message". It shows up in Winspector Spy as:
UWM_SHOW_BUSS_OUT-{F8C1103C-156D-4395-A922-42472183FC14) (Registered messages)
wParam and lParam are both 0x00, so that part is easy.

My question is, is it possible to send registered messages, and if so, how do I get the message code for this particular message?

Thanks,
Tom

what's the app?
in case i have it (or its a miniscule download) then i might be of more help.

If you you haven't already, you might try ControlClick, or "ControlSend, ClassNN, {Enter}, WinTitle. You could also try sending {Space} in place of Enter, and if that doesn't work, a ControlFocus beforehand.

I don't know, but maybe someone else does (or Google).

Thanks for the help guys.

Rajat, I doubt you have the app. It is an audio app made by Brainspawn called forte. It is a virtual instrument host designed for live use.

Chris, unfortunately, the ClassNN for this control changes each time the app is opened.

I take it from your last comment that it should be possible to send registered messages using the postmessage command, but that you don't know how to determine the message number for a given message name. Is that correct?

Thanks again,
Tom

i've never encountered such a msg with any app, so can't help you with my experience. but if u eventually figure something out abt this, then do let me know!

Here are some possible ways to work around that:
Use the control's text instead of ClassNN to access it.
Use the X/Y mode of ControlClick's first parameter to access it.
Use "WinGet, ControlList, ControlList" to get a list of the controls. Have the script analyze that list to determine which control to try a command on.

I don't know if it's possible or how to do it.

Good luck.

Thanks again for the help guys. This particular control is quite elusive - the ClassNN changes every time the program runs, and it has no text - just a graphic. The name is always 'ButtonX', where X is some number.

I think I will have to use the X,Y of the control as Chris suggested. I was trying to avoid this because this app is skinnable, and I want the command to work even if I later change skins.

Nothing in this world is ever perfect...
