Newbie: Event handling in vb.net

zeppozeppo Member Posts: 8
Hi
I have just graduated to vb.net from vb6 and I am having problems with the Event handling structure.

In vb6 I could use the event below:

Private Sub Cell1_OnRowChange(ByVal oldrow As Long, ByVal newrow As Long)

In this case I could directly access oldrow and newrow directly e.g TextBox1.Text=newrow

The new definition in vb.net is thus:

Private Sub AxCell1_OnRowChange(ByVal sender As Object, ByVal e As AxCELLLib._DCellEvents_OnRowChangeEvent) Handles AxCell1.OnRowChange

(This appears to be the format for all events in vb.net)


How do I now access oldrow and newrow using this method???

Yours with many thanks

Mark Lea

    Hi Mark

    Event handling in VB.Net goes like this:-

    sender - is the object (control) that is the event source

    e - is the event object that supplies event data

    'e' may supply no event data as in the 'Click' event
    -or-
    details about button state mouse coordinates etc for
    the 'MouseDown' event.

    The event data depends upon the event type.

    Unfortunately I do not have AXCell on my computer is it
    an ActiveX or is it part of Visual Studio?

    If in the event handler you type e. that's an 'e' and a 'dot'
    a list of the members associated with the event object
    should be displayed or you can use the object browser to
    list all members associated with a particular event object.

    In the Visual Studio documentation there is a detailed info
    about event handling do a search for 'Events and Event Handlers'
    and bookmark the pages.

    Hope that helps
