Best way to simulate a button click within your own GUI

6 posts in this topic


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.

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. :)


Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind._______My UDFs:


ArrayMultiColSort ---- Sort arrays on multiple columns
ChooseFileFolder ---- Single and multiple selections from specified path treeview listing
Date_Time_Convert -- Easily convert date/time formats, including the language used
ExtMsgBox --------- A highly customisable replacement for MsgBox
GUIExtender -------- Extend and retract multiple sections within a GUI
GUIFrame ---------- Subdivide GUIs into many adjustable frames
GUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView items
GUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeView
Marquee ----------- Scrolling tickertape GUIs
NoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxes
Notify ------------- Small notifications on the edge of the display
Scrollbars ----------Automatically sized scrollbars with a single command
StringSize ---------- Automatically size controls to fit text
Toast -------------- Small GUIs which pop out of the notification area

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


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
