Prevent Screen flickering during event

Question

Hey guys, I know that in primitive versions of vb (as found in excel) there was a line that you could insert to prevent screens from flickering to and fro when it is trying to process something.

Application.screenupdating = false

I am currently using vb.net in Visual Studio 2008 but i was wondering if anyone knows the equivilent for this version. It doesnt recognise this call in VS 2008 using vb.net. Any help would be appreciated! Thanks in advance guys!

Answer 1

Depends on control. Quite a lot of controls (e.g. ListView) have BeginUpdate and endUpdate methods that server that exact purpose.

list.BeginUpdate()
list.Items.Add(...)
list.Items.Add(...)
list.Items.Add(...)
...
list.EndUpdate()

Answer 2

Globals.ThisWorkbook.Application.ScreenUpdating = False

Answer 3

The SuspendLayout and ResumeLayout methods should do the trick. SuspendLayout prevents a control/form from redrawing itself until you call the ResumeLayout method.

Answer 4

re: when it is trying to process something

you can disable the form
