C#3.5

hi,

I got the above exception while saving my image. Please help me out.
My code is below....

Using SaveDialog i pass the inputpath and outputpath parameters to the CONVERT_TIFF() function.

Actually i save an particular image inside my application path as "Bitmap" and Convert it into "TIFF" using compression
