Onpaint and Invalidate question

[Colin McGuire]

Hi, I am just learning "how-to" by reading some of the existing
article solutions in this newsgroup. I happened to come across this
one. Tom Spink knows what he is talking about and I am wondering why
he has done something.

My question is how does this work

<pseudo>
Function To Override OnPaint(...)
Call Base Class OnPaint(...)
Me.Invalidate()
End Function
</pseudo>

My understanding was that Invalidate() raises an OnPaint(..) event, so
therefore this should be recursive shouldn't it?

Thank you
Colin

Try overriding the OnPaint event, then invalidating the form:

<pseudo>
Function To Override OnPaint(...)
Call Base Class OnPaint(...)
Me.Invalidate()
End Function
</pseudo>

Yes it is recursive. By the way, did you look at your
scrollposition ---can't de determined post? I think I found your solution.
Go take a look!

I think what is written below would be a very, very bad thing. Where did
you see the source?
