form nothing

private withevents frm frmfullscreen   private sub updateimageinguiasync(byval bm system.drawing.bitmap)           if me.frm.invokerequired = true             dim dl new bitmapdelegate(addressof updateimageinguiguithread)             if me.frm isnot nothing me.frm.invoke(dl, bm)         else             call me.updateimageinguiguithread(bm)         end if      end sub

any idea how fix this?

is possible form disposing?

if so, i'd wrap entire if block in try/catch.
