Problem with gui ctrl set data

[kor]

#include <GUIConstantsEx.au3>
#include <ProgressConstants.au3>

Opt('MustDeclareVars', 1)

Example()

Func Example()
    Local $progressbar1, $progressbar2, $button, $wait, $s, $msg, $m
    GUICreate("My GUI Progressbar", 220, 100, 100, 200)
    $progressbar1 = GUICtrlCreateProgress(10, 10, 200, 20)
    $button = GUICtrlCreateButton("Start", 75, 70, 70, 20)
    GUISetState()
    Local $i = 0
    Do
        $msg = GUIGetMsg()
        If $msg = $button Then
                    GUICtrlSetData($progressbar1, $i += 10)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i += 10)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i += 10)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i += 10)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i += 10)
                    Sleep(300)
        EndIf
    Until $msg = $GUI_EVENT_CLOSE
EndFunc   ;==>Example

Modified sample script from the GuiCtrlCreateProgress

When I try and run I get an error parsing function call with the $i += 10

I'm not sure why I can't preform this operation.

Hi, kor. A couple of ways you can do it, as GUICtrlSetData does not like the += attempt at incrementing. From your example, this is the simplest:

#include <GUIConstantsEx.au3>
#include <ProgressConstants.au3>
Opt('MustDeclareVars', 1)
Example()
Func Example()
    Local $progressbar1, $progressbar2, $button, $wait, $s, $msg, $m
    GUICreate("My GUI Progressbar", 220, 100, 100, 200)
    $progressbar1 = GUICtrlCreateProgress(10, 10, 200, 20)
    $button = GUICtrlCreateButton("Start", 75, 70, 70, 20)
    GUISetState()
    Local $i = 0
    Do
        $msg = GUIGetMsg()
        If $msg = $button Then
                    GUICtrlSetData($progressbar1, $i + 10)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i + 20)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i + 30)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i + 40)
                    Sleep(300)
                    GUICtrlSetData($progressbar1, $i + 50)
                    Sleep(300)
        EndIf
    Until $msg = $GUI_EVENT_CLOSE
EndFunc   ;==>Example

I cheated and took the easy way out.

$iBarCount += 5 ; step the precentage
        GUICtrlSetData($hBar, $iBarCount) ; set the progress bar percentage
        Sleep(200) ; sleep to allow time to see progress step and read messages

Easy is what we're aiming for. Glad you worked it out
