Hi
I am displaying a list of images from a local directory using, listview and imagelist.
When the user selects an image(image1) and clicks a button i perform a rotation on that image and then save the rotated image(image1r) in the directory.
Now i want to delete the original image (i.e image1) from the directory, but when i try to do it.
i get this error

An unhandled exception of type 'System.IO.IOException' occurred in mscorlib.dll

Additional information: The process cannot access the file "C:\Documents and Settings\Komal\My Documents\My Pictures\friends\1005-003-84-1042.gif" because it is being used by another process.

I tried, disposing the imagelist, the listview, the bitmaps and graphics i am using to rotate the image. I even cleared the listview and imagelist and also set all the variables i am using to nothing but still i keep getting the same stupid error.
ANy ideas..?

a windows process is prolly useing the file which is why you're getting the error, make sure the system is done with the file first.

When Michaelk says VS is using the image, he means Visual Studio (the program used to create the application). Is VS using the file?

Post your code if you still need a solution :)
