could not get list count using ControlListView

7 posts in this topic

Hi all,

I am working on a window application and facing problem getting a list count. I've used the following functions, even though there are rows/list items present in WinList box every time it is returning 0 value. Please help on this.

1. ControlListView ("Window Name", "", 123, GetItemCount)

2.  _GUICtrlListBox_GetCount(123)

123 is the Control Id of the object(Win List) in "Window Name"

Listbox or Listview? You're mixing your control types. If you have a listview use _GUICtrlListView_GetItemCount. Also, make sure you're using the correct handle, because 123 doesn't look like a handle identifier.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

hi,

Here 123 is the control ID. I am not using the Handler here. Can you please explain more? Generally for getting a List count which is preferred and how can I get handle of an object in a window?

Use ControlGetHandle ( "title", "text", controlID ) to get the handle, the ListView UDF needs the handle, you're giving it the control ID. Check to make sure that ControlGetHandle returns a handle before trying to use the listview function, if you're not able to get the handle, you won't be able to get the count. Also, if you can't get the handle using it, then perhaps your control ID is incorrect.

WinActivate("XYZ Window")

Local $hWnd= ControlGetHandle("XYZ Window", "",123)     ;*123- is the control Id, got from AutoIt window Info->Control -> Id 

$iHcc= ControlListView ( "XYZ Window", "", $hWnd, "GetItemCount")
MsgBox(0,"",$iHcc)    ;* is returning 0

Please check and let me know.

_GUICtrlListView_GetItemCount is the function that needs the handle to the control, ControlListView needs the control ID. Use _GUICtrlListView_GetItemCount with the handle and see if that works for you.

Also, there's no way for me to check this, because I don't know what it is you're trying to access.
