Binding picture box?

[mythinky]

I am binding a picture box. I have format the picture box to ensure it's not bind to an empty path or invalid path or invalid file. But problem raise, after formating the binding picture, the form doesn't load correctly. After <B> form1.Show() </B> executed, it doesn't call form1_load. But if i am not formating the binding picture, it will execute the f0rm1_load after it execute the<B> form1.Show() </B>. Is there any other code I need to put to the form1? Or what actually the problem?
Thanks. Please help me!!!
