[RESOLVED] Has object already been set?

[aikidokid]

How can I check to see if an object has been set or not?
I have this code in my form, that relates to a class (I can post if needed), but if the object has already been set I obviously get an error.

Set oPic = New CMDIPicture

     'The Init method takes the MDI form and a standard picture object
     'as argument. Instead of LoadPicture you can pass the Picture property of
     'any PictureBox or Image control or Load an image from a resource file.
            
oPic.Init MDIMain, LoadPicture(App.Path & "\Image.jpg")

I just don't know how to check before I run this code.
