can't get handle since ListView changed?

[zjsong]

 

I have a software, that TreeView on left side and ListView on right. Once select different items on TreeView then ListView will change, also its handle change.

 

The problem is I can't get the handle of changed ListView and its items, I can get the first one only. 

 

how to do in this case? Thanks for your help

 

 

#include <GuiTreeView.au3>

$w="[CLASS:TdxW_MainFrame_Class]"
$id_TreeView="[id:59650]"
$id_listView="[id:100]"

WinActivate ($w)
WinWait($w, "", 5)
$h_TreeView  = ControlGetHandle($w, "",$id_TreeView )

;select TreeView item AA
ControlTreeView($w, "", $id_TreeView, "Select", "AA")
$h_treeItem=_GUICtrlTreeView_GetSelection($h_TreeView )
_GUICtrlTreeView_ClickItem($h_TreeView , $h_treeItem, "left", False, 1)

$h_listview_1=ControlGetHandle($w, "",$id_listView );get correct listvieew handle
$itemtext_1=ControlListView ($w, "", $id_listView, "GetText" ,0,0);get correct text

;select TreeView item BB
ControlTreeView($w, "", $id_TreeView, "Select", "BB")
$h_treeItem=_GUICtrlTreeView_GetSelection($h_TreeView )
_GUICtrlTreeView_ClickItem($h_TreeView , $h_treeItem, "left", False, 1)

$h_listview_2=ControlGetHandle($w, "",$id_listView );get wrong listvieew handle
$itemtext_2=ControlListView ($w, "", $id_listView, "GetText" ,0,0);get wrong text

Without having or knowing the software it's very difficult, but I'd say your problem almost certainly lies here...

$id_listView="[id:100]"

If the ID is changing then obviously you will not get your control.

Show the summary tab of listview from window info tool before and after you select new treeview item.

What if you go back to the prior treeview item, does the listview instance return of go to 3?

No, it always keep instance as 1. When I click new item in TreeView it will create a new instance and new handle for ListView that have same ID, and then those instance/handle always keep their own number. The old listviews are hidden till go back.

I just want get handle of 2, 3, 4.... but it only give me handle of 1.

Then all I can suggest is to keep track of the instance of the control (perhaps in an array) for each treeview item you click on.

Thank you

It's also worth having a go at UIAutomation, you'll find UDFs and examples sticky in example scripts.
