    how can I check to see if something is null?

    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.
