Sorry for the blank post,

I clicked to fast,

you can check to see if the picturebox is empty like this:

if picturebox1.image is nothing then
msgbox("I'm empty")
end if

It's Image property will not be "Nothing".

If Me.PictureBox1.Image Is Nothing Then

Alternatively you can use the 'IsNothing' function.

then what is the differnce between "is" and "=" in VB .net ?

With = you can see if a value of a property = Something

With "Is" you can see of the address of a referenced object is Something

I hope this helps,
