TreeView Hangs

[MartinLiss]

Try doing TreeView1.Nodes.Clear before you unload the form. If that doesn't work please post the code you use to end the program.

I tried inloading the nodes but that didn't solve the problem. Here's the code used to close the program.

Private Sub cmdQuit_Click()
 
    ' Clear the nodes
    TreeView1.Nodes.Clear
    ' Unload the Form
    Unload frmListView
    ' Close and End
    Close: End
 
End Sub

I've attached a zip file containing the project. Maybe you can spot something there. (excuse the coding, I'm self taught)

Thanks,

There's nothing wrong with the code you show. I'm a little concerned about the Close: label and I hope you are not doing a GoTo Closesomeplace in the Sub. If you aren't then it doesn't hurt anything but you don't need the label.

I think I remember someone else having a problem closing a form that had a large treeview. It will probably be hard to find but you might use the Advanced Search and look for something like treeview close and see what you can find.

Hi Marty,

The "Close: End" is not a Close label, I just put the two statements on the same line separated with a colen. i.e.

Close
End

I'll do another search and see if I can find an answer. This one sure has me baffled! Thanks for your help.

Remove the Close. You don't need it.

I'm not sure what's causing your issue, but one thing to consider is dynamically populating the childen nodes when the parent node is expanded - i.e., load only the countries first - then when a country is expanded, load the corresponding states - when the state is expanded, load the cities - and so on. (you could even remove the children nodes when the parent is collapsed)

This of course requires a bit more coding on your part, but it will keep the node count to a minimum ...
