NotSupportedException for PictureBox image

[King Abadon]

I have an error in my pocket application.If i debug the application on Pocket emulator it works fine .But if i run on a Pocket pc i get this error:
NotSuportedException
System.Drawing.Bitmap
Any ideas?

What code is being executed when the exception is thrown? Was the device running the same OS version as the emulator you tested it on?

this is the code

this.pctS.Image = ((System.Drawing.Image)(resources.GetObject("pctS.Image")));

I think i figured it out.When i debug ,if i deploy System.Drawing.dll on the Pockett it doesn't work.
