After Form Load Event?

[Mike Hildner]

Is there a way to launch some code after the Form_Load method executes? I'm having some trouble in a MDI child. When I put the code I need to execute in the Form_Load, I get an OutOfMemoryException, but if I put this code under a button click in the child form, things work fine.

Thanks,
Mike

What about if you place the code into a Sub, which you call from the Form_Load?

Also, you could call another event like

Call Event_Name(Nothing, Me) 'for args, sender

Thanks, mendhak, problem solved. Placing the code in a method called from Form_Load does not work, generating the same exception. But calling a public method after Form.Show to execute the code works fine.

Not sure why it works, but it works. Thanks!

What exactly are you doing that's not working in the Form_Load?

Maybe that'll give us a clue...

I agree with mendhak. I have no problem with calling from the load event of a child. It must be peculiar to what you are coding.

Populating a tree view with tables from a database. This is done through a web service. This is in C#, but should be interpretable to VB folks:

            PatriotWebService.PatriotClientWebService ws = new PatriotWebService.PatriotClientWebService();
            dsTables = ws.GetUserTables();
            // There's only one table in this data set, get it,
            // and run through all the record in it, populating the
            // tree view.
            DataTableCollection dtc = dsTables.Tables;
            DataTable dtUserTables = dtc[0];
            foreach (DataRow row in dtUserTables.Rows)
            {
                //tvTableList.SelectedNode = 0;
                //tvTableList.Nodes.Add(row["name"].ToString());
                tvTableList.SelectedNode.Nodes.Add(row["name"].ToString());
            }
            tvTableList.ExpandAll(); 

Initially, I had the above code in Form_Load. I used this code in the MDI container:

            Tables t = new Tables(); // Tables is a Windows form
            t.MdiParent = this;
            t.Show(); 

When this code was in the constructor of the MDI parent, all went well. I moved it to execute when you click a button, and when that happened, I got an OutOfMemoryException.

A useful event for doing things once after form load is complete is the form's Shown event.

Probably an error because the controls you are trying to load haven't initialized yet ?

A useful event for doing things once after form load is complete is the form's Shown event.

Given that this thread was created in 2004, before .NET 2.0 was released, Shown wasn't an option. It certainly would be nowadays, but back then we had to use the Activated event with a Boolean variable to indicate whether it's the first time or not.
