Best way to simulate a button click within your own GUI

[Lantz]

Hey!

What is the best way to simulate clicking a button within your own gui?

Background: I have two buttons next and previous, when clicked they increment or decrease an integer variable that is then used to tell a different part of the program what page to display. But to update and show the new display I currently manually have to click a button.

I have tried using controlclick but i am reluctant to use any command that references the title of the window as that might change in the future.  I have tried passing the handles of the window and the handle of the button to controlclick without success. 

 

ControlClick($RunCommands[0][2],"",$RunCommands[11][2])

Lantz,

Place the code to run when the button is pressed within a function - then when you need to simulate a button press you just run the function programatically.

Solved my own problem, it´s debatable if its the best solution but certainly good enough for me:

 GUICtrlSendMsg($RunCommands[11][2],$BM_CLICK,0,0)

This simulates a button click on button $RunCommands[11][2]

 I though maybe this time i will be fast enough to figure out the problem for my self before you do, but I guess you cant beat a dragon

The idea to place the "task" in a function had accrued to me, but honestly I wanted to figure out/learn away to do it this way instead to see if it was possible.

Found this in the help file:
 

; Post a WM_COMMAND message to a ctrl in a gui window
Func PostButClick($hWnd, $nCtrlID)
    DllCall("user32.dll", "int", "PostMessage", _
            "hwnd", $hWnd, _
            "int", 0x0111, _    ; $WM_COMMAND
            "int", BitAND($nCtrlID, 0x0000FFFF), _
            "hwnd", GUICtrlGetHandle($nCtrlID))
EndFunc   ;==>PostButClick
