Send/Receive data from external listview

[Monica]

Hi guys!! I'm going crazy... please help me -.-

First, open the attached screenshot. Second: I'd like to grab info from external window. The program is "Metatrader4", a tool for trading and charts analysis.

The function _GUICtrlListView_GetItemText() return an empty string! I tried to change the index $index (the second parameter) into Number($index), as recommended by other similar posts in this forum, but this did not solve my problem 

Well, why I'm going mad? Because in my mind an UDF approach works great or it does not work at all; instead, in my code something works and something else does not. I really don't understand why... and you?

THXX!!!!  

$handle=ControlGetHandle("Expert - "&$expertname,"",1383);List: Variable|Value
For $i=0 To _GUICtrlListView_GetItemCount($handle)-1;WORKS!!!
    $temp=_GUICtrlListView_GetItemText($handle,0+$i);RETURN EMPTY STRING :-(
    MsgBox(0, "", $temp)
    $temp = _GUICtrlListView_GetItemSelected($handle,$i);WORKS!!!
    MsgBox(0, "", $temp)
Next

What about if you include the third parameter 'sub item'...maybe getting each value independently will work.

Hi jdelaney,

not work for me :-( the 3d param is 0 if omitted; i try with 1,2,3... the getText string is empty 

Not a lucky question  but i really don't understand this behavior. The child item is recognized but fewUDF functions does not work properly. Another idea? 

Thanks, M.

well...if *_getitemselected works, you can loop through selecting each and calling that...either that or just trying each _guictrllistview* function until you get your result is all I can tell you.

Try to use native ControlListView() instead of UDF's  _GUICtrlListView_xxx()
