Hi All,

I am using webbrowser control, it is very often to happen:

A first chance exception of type 'System.IO.File NotFoundExcepti on'
occurred in System.Windows. Forms.dll

but sometimes works, all the same code, what's the problem...and how to
resolve it...

Thank you very much.

Best regards,
Boki.

Boki,

Is this when you are debugging, running, or whatever.

Can you show us the code where this happens?

Boki,

Why do you not set the 2 or more webbrowsers in a Tabpage or a
splitcontainer. No problem as all.

I hope this helps,

Boki,

Just drag a tabcontrol on your form
Drag in the tabpages the same as you did it now on the form, not so much to
learn.

Problem is that it is more dragging than code. Therefore I cannot even give
you a sample.
