GUI Listview function

[mcgill]

Hello all,

I need some help with the gui listviewitem function. What I am trying to do is load a file into a listview by a click of a button. But on this GUI I will have a few other buttons that load different files into the listview. I am having problems clearing the listview before I load the other file into the list. I have tried GuictrlDelete function but it was not clearing the listview. Basically in my code I should clear the list before I load the other file into the listview. I also think there is a problem with me loading the file into the listview. Should i have to create another array when loading each item/row into the listview. If anyone can help me with this it would be greatly appreciated, thanks

At a glance, it appears you are trying to create a new listview item everytime you want to update the listview control. This is not necessary. If the listview item already exists and you just want to update the info inside of it, use GUICtrlSetData(). There is no need to delete the control unless it is no longer needed. If you need to delete the control and it's not deleting, then maybe try hiding the control.. dunno, I've never had that problem, or maybe try deleting the entire listview and re-creating it.

Here's a problem I found:

Func BranchCodingGreen() 
if $y = $item1 then 
        Msgbox(0,"Error","You have already clicked this button") 
else 
 $file = FileOpen("C:\Documents and Settings\amcgill\Desktop\SDT\Branch Coding\Branch Coding Green.txt", 0) 
 ; Check if file opened for reading OK 
 If $file = -1 Then 
  MsgBox(0, "Error", "Unable to open file.") 
  Exit 
 EndIf 
 ; Read in lines of text until the EOF is reached 
 While 1 
  $line = FileReadLine($file) 
  If @error = -1 Then ExitLoop 
  $y=StringFormat ("%s",$line) 
  $item1= GUICtrlCreateListViewItem($y,$listview) 
        Wend 
      
        $item1 = $y  ;<<==  you deleted the control ID for the control ;)
            
        FileClose($file) 
EndIf 
EndFunc

Thanks for the help all, I tried using the #include <GUIListView.au3> but I keep getting error reading file. Is there a certain version I should be using to use this library. I am using version 3.1.1. ?

Hi,

the code I posted needs beta.

That still doesn't change the fact that he is storing his control ID in $Item1 when it is created, and then overwriting it with the variable holding the return value of StringFormat("%s", $line). With no control ID it's no wonder that the controls cannot be deleted.
