heinduplessis Posted July 2, 2012 Share Posted July 2, 2012 I've done some searching through the forum but can't find exactly what I need - I might have it on it but I'm very new to AutoIt so I get confused easily I just need to send a WM_COMMAND to a window handle and gui element ID. The "traditional" winapi code is: PostMessage(h,WM_COMMAND, BN_CLICKED, id) where h is the top level window handle and id is the id of the button I need clicked. I'm sure it's just a few lines of code but for the life of me I can't hack it. Many thanks. Link to comment Share on other sites More sharing options...
Skitty Posted July 2, 2012 Share Posted July 2, 2012 (edited) Use the sendmessage functionDllCall("user32.dll", "lresult", "SendMessage", "hwnd", $WindowHandle, "uint", $Windows_Message, "wparam", $wparam, "lparam", $lparam);0xFFFF = all windows Edited July 2, 2012 by ApudAngelorum Link to comment Share on other sites More sharing options...
heinduplessis Posted July 2, 2012 Author Share Posted July 2, 2012 (edited) Use the sendmessage function DllCall("user32.dll", "lresult", "SendMessage", "hwnd", $WindowHandle, "uint", $Windows_Message, "wparam", $wparam, "lparam", $lparam);0xFFFF = all windows Thank you very much for your reply. So, if I understand correctly, to replicate my sample above, I can send: DllCall("user32.dll", "lresult", "SendMessage", "hwnd", 131816, "uint",273, "wparam", 0, "lparam", 4427); 131816 = Window Handle 273 = WM_COMMAND 0 = BN_CLICKED 4427 = ID of button I've tried it but don't get the expected result, the button seems not to have clicked. Is there something wrong with my implementation? Edited July 2, 2012 by heinduplessis Link to comment Share on other sites More sharing options...
Skitty Posted July 2, 2012 Share Posted July 2, 2012 I just noticed that your attempting to use this to simulate clicking on a button. Why not just use the controlclick command? Link to comment Share on other sites More sharing options...
BrewManNH Posted July 2, 2012 Share Posted July 2, 2012 Never hard code the window handle value into your script, it will change every time you run it. If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.

Zedna Posted July 2, 2012 Share Posted July 2, 2012 (edited) You can use _SendMessage() from standard include file Misc.au3Here is similar use with WM_SYSCOMMAND Edited July 2, 2012 by Zedna Resources UDF ResourcesEx UDF AutoIt Forum Search Link to comment Share on other sites More sharing options...
