Did I do something wrong ?

[jaberwacky]

So the first picture is before or after you lock your computer?

I don't have a problem with the scrollbar not showing. It shows both before and after I lock my computer. If I scroll about halfway down the list, lock my computer, unlock my computer, then the scrollbar is where I left it. Is that the problem?

The first picture is after I lock/unlock my Computer.

If I minimize and maximize the Gui or after first start it is ok (pic2).

I have the Problem only with Tabs. Without Tabs I have no problem with Listview and lock/unlock.

After lock/unlock an click on Scrollbar you can see the Scrollbar. See Screenshot.

Well, I don't have a problem with the scrollbar on either my Windows 7 x64 machine or my Windows XP x86 virtual machine. So, I dunno what to tell you. Maybe someone else can help you because it's possible that I still don't understand the problem?

Hmm I test it on 2 WinXP SP3 Clients and a virtual Vista maschine. Always the same problem. If I start the test code above it looks good. If I press Ctrl+Alt+Del and go back the Scrollbar and some empty area from the listview are gray.

If I minimize the Gui or scroll or change a Tab it is Ok... strange :-/

If I test the same code without GUICtrlCreateTab no problem with Ctrl+Alt+Del.

But thx for testing jaberwocky6669

Local $Gui = GUICreate("Test", 300, 200)
Local $tab = GUICtrlCreateTab(5, 5, 290, 190)
Local $tab1 = GUICtrlCreateTabItem("Tab1")
Local $hListView = GUICtrlCreateListView("Test1 | Test2| Test3", 10, 30, 280 , 160)
Local $tab2 = GUICtrlCreateTabItem("Tab2")

    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
    Sleep(10)
WEnd

With this small code I have the same problem with one difference. I need to lock (Ctrl+Alt+Del) my system two times befor the Listview is gray.

Hi

I found mein problem.... $LVS_EX_FULLROWSELECT

Without $LVS_EX_FULLROWSELECT I have no Problem with the Gui. With $LVS_EX_FULLROWSELECT I have a greyed Listview after lock System (Ctrl+Alt+Del) but only if I use Listview with Tabs. Without Tabs it works fine.

<- Without FULLROWSELECT after lock System (Ctrl+Alt+Del)

<- With FULLROWSELECT after lock System (Ctrl+Alt+Del)

#NoTrayIcon
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Local $Gui = GUICreate("Test", 300, 200)
Local $tab = GUICtrlCreateTab(5, 5, 290, 190)
Local $tab1 = GUICtrlCreateTabItem("Tab1")
Local $hListView = GUICtrlCreateListView("Test1 | Test2| Test3|", 10, 30, 280 , 160, -1, BitOR( $WS_EX_CLIENTEDGE, $LVS_EX_FULLROWSELECT,  $LVS_EX_GRIDLINES)) ;Problem
;Local $hListView = GUICtrlCreateListView("Test1 | Test2| Test3|", 10, 30, 280 , 160, -1, BitOR( $WS_EX_CLIENTEDGE, $LVS_EX_GRIDLINES)) ; no Problem 
Local $tab2 = GUICtrlCreateTabItem("Tab2")
GUISetState(@SW_SHOW)

;GUICtrlCreateListViewItem("a|b|c", $hListView)


While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
    Sleep(10)
WEnd
Exit

Have someone a solution for me or can test the code ? I need $LVS_EX_FULLROWSELECT...
