Hi There,

I have this form in VB6 in which I have several ListViews. Turns out that I have a For/Next loop to run in each one of those listviews, however I did not want to have to rewrite the loop for each one of the listview. So, I am now trying to find a way to create a method/function in which I pass the ListView control to, run the loop in the items in that list, performing the changes as necessary such as checking on/off the check box, and then returning the revewed listview back from that function.

Something like....

Private Function ChangeListView(lvwX as ListView) as ListView
   For i = 1 To lvwX.ListItems.Count
     if lvwX.ListItems(i).Text = "abc" then
        lvwX.ListItems(i).Checked = True
     end if
   Next i
End Function

Then I would do....
ListView1 = ChangeListView(ListView1)

Everything goes well until I return from my function with my changed listview. I won't let me make the ListView1 = My new Listview

Suggestions?!

Thx a bunch..

Ed.

Hi

When you asign reference variables you need to use the set keyword, for example
set ListView1 = ChangeListView(ListView1)

however, I think tha'ts not what you need. Perhaps you just need to run your function as is, without needing for assing nothing, e.g.

Private Sub ChangeListView(lvwX as ListView)
   For i = 1 To lvwX.ListItems.Count
     if lvwX.ListItems(i).Text = "abc" then
        lvwX.ListItems(i).Checked = True
     end if
   Next i
End Sub

ChangeListView(ListView1)
