Listview with Checkboxes (Help)

2 posts in this topic

#1 ·  Posted (edited)

Using the following code provided by gafrost (thank you) I would like to take this listview a step further. Sending the data to a new listview but only by the ones that are checked off.

Pressing the button at the top will copy the data into the listview on the right. This is where I am stuck.

Any Ideas?

You need to add this line to the start of your script

#include <guilistview.au3>

Then the case statement would be like this

Case $msg = $copy
            For $n = _0 to GUICtrlListViewGetItemCount($listview) -1
                If _GUICtrlListViewGetCheckedState($listview,$n) Then
                    _GUICtrlListViewCopyItems ($listview,$output_listview, 0)
                EndIf
            Next

You might need to add something to stop the same items being copied more than once.
