in vb6 there was Null and IsNull that we could use, but I dunno how to it in VB.Net. For example how can I check to see if the image of a picturebox is null or not?

thanks in adance:)

Try using "Is Nothing".

I'm not sure as I'm not at my computer.

For datatypes you can use ex: if myString = System.DBnull.Value then....
