Passing the button instance through a variable in ControlClick

[geekforu]

hi,

I am new to Autoit and was wondering how to pass the button instance parameter as a variable in ControlClick. I need to read the button instance from a file (e.g. 5), store it in a variable and then need controlclick to click on that button instance. I tried concatenation something like this :

$firstnum = "[CLASS:Button; INSTANCE:" & $instanceVariable & "]"

ControlClick($hWnd3, "", $firstnum)

It does not work and throws error in the first line saying illegal format. Please help me regarding this. Thanks in advance

Good attempt, look up ControlGetHandle() in the help file.

This example appears to work.

Run("calc.exe")

WinWaitActive("Calculator")
Local $hWnd3 = WinGetHandle("Calculator")

Local $instanceVariable = 42 ; Button42 is button 7 on calculator.

Local $firstnum = "[CLASSNN:Button" & $instanceVariable & "]"
ControlClick($hWnd3, "", $firstnum)
; or
$firstnum = "[Class:Button; Instance:" & $instanceVariable & "]"
ControlClick($hWnd3, "", $firstnum)
; or
$firstnum = "Button" & $instanceVariable
ControlClick($hWnd3, "", $firstnum)

Edit: Added the last example of using the ClassnameNN property of the control as the controlID parameter in the ControlClick() function.

I'd suggest outputting the concatenated string via a MsgBox to see what is actually passed as a parameter to ControlClick. Since you mentioned reading some data from a file and storing that into a variable, I'm guessing that the error may lie with the data you read and/or the way you handled that data.

I would do something like this

Global Const $appHandle = WinGetHandle("[ACTIVE]")

Local $bHandle = ControlGetHandle($appHandle, "", "[Class:Button; Instance:" & $instanceVariable & "]")
If $bHandle == "" Then
    MsgBox(0, "Handle Error", "button handle not obtained")
EndIf

ControlClick($bHandle, "", "")

Safer code.
