Trouble automating a TreeView in an application

Recommended Posts


I am trying to manipulate an application that has a "TreeView" list within it. I am using the "_GUICtrlTreeView_FindItem" command to search for the desired "child" branch in the TreeView, and upon finding it then assigning it a handle so as to "double click" that child so as to open/expand it...

$hHandle = ControlGetHandle("History", "", "[CLASS:SysTreeView32; INSTANCE:1]")
$hItemFound = _GUICtrlTreeView_FindItem($hHandle, "APPLES", TRUE)
If $hItemFound Then
MsgBox(4160, "Information", "Item Found:")
$hItem = ControlGetHandle($hItemFound, "", "[CLASS:SysTreeView32; INSTANCE:1]")
_GUICtrlTreeView_ClickItem($hHandle, $hItem, "left", False, 2)

The above code does not throw any error and it seems to run OK, however I do not see the "TreeView" within the application expanding on the desired child, or doing anything at all. What am I missing here? I have not tried to manipulate TreeView commands before so if somebody could inform what I am not understanding I would greatly appreciate it...thank you in advance.

I replaced that "ClickItem" line with:

ControlTreeView("History", $hItemFound, "[CLASS:SysTreeView32; INSTANCE:1]", "Expand", "Heading1")

However it doesn't seem to have made a difference...

Thanks, I added these lines:

_GUICtrlTreeView_Expand($hHandle, 0, False)  ;COLLAPSE ALL
    _GUICtrlTreeView_Expand($hHandle, $hItemFound, True)

It does successfully collapse all of the TreeView items however I still cannot get the desired 'child' to expand...the only thing I have had success with is expanding ALL the TreeView items...?
