Nice show! Use one of the overloaded Save methods on the returned 'i' Bitmap or the 'img1.Image'. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemdrawingimageclasssavetopic.asp

By the way, your user profile shows Primary Platform .Net 2.0, but the attached project is .Net 1.1. Please update you user profile or state the platform with the request when it differs from the primary one.

this code is not written by me. i got it from net. can you give me example of how to save?

 

[JohnH]

img1.image.save(filename)

 

[david_reinjal]

it is not working. it says filename not declared.

 

[david_reinjal]

and even after declaring itas string. it says An unhandled exception of type 'System.NullReferenceException' occurred in GDIPlus.exe

 

[JohnH]

Did you ever think to actually set a filename in that string?

img1.Image.Save("bitmap.bmp")

Image.Save Method (String)

Parameters

filename : A string that contains the name of the file to which to save this Image object.
