Hi,
I have a WebContainer on a WebPage.
When I select, the first time I have a “This application has encountered an error and cannot continue.”. I clic “Do not send”, and select another line and it gives me the previous selection.
What did I miss?!?
[code]Session.p_id_Client = ClientList_CCtrl1.Client_ListBox.Cell(ClientList_CCtrl1.Client_ListBox.ListIndex,0)
MsgBox(Session.p_id_Client)
[/code]
Code of Listbox
Think I fixed it for you.
Take a look at what I did and see if you can spot what you missed

Thanks Albin. Fixed it in my app…
When I tried to fix the problem before I post, I began to wrote [quote]Row as Integer, Column as Integer[/quote] in the parameters of the event definition, BUT since Xojo did not offer me the choices, I thought I was off…
I saw the Highway, but did not know how to get on it! Need more and more practice…
