Hello,
I am getting a General GDI+ Error according to the Visual C# debugger. i have no idea as to how to handle this problem. I have a button which i click and a section of the screen is cut and put into a bitmap. This is converted into tiff format which is sent for OCR using MODI. The first time I click the button it works, however, when i click the button again, I get a the error. Here is the line it is being pointed to:

bitonalBitmap.Save(@"c:\Bitonal-Out.tif", imageCodecInfo, encoderParameters);

Can anyone help me please.
Thanks in advance.

Sorry, should have posted that as well...

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Maybe this will help... I tried to delete the Bitmap after and was getting a "File used in another process error" which i also posted on another thread

Do you dispose of all your resources after the 1st button click? Do you specify a filename or is it a static filename you are using? sorry for all the questions im trying to determine more or less what may be the cause of this exception
