I have asp.net code using C# that will convert tif file into jpg and then it
display them. The program works on my machine and Dev machine with Window XP
professional. When I deploy the program on test machine (window 2003 server)
I get error:

Argument Exception Invalid parameter used"

The code that causes the error is:

byte[] imgbyte;
MemoryStream memStream = new MemoryStream(imgByte.Length);
memStream.Write(imgByte, 0 , imgByte.Length);
System.Drawing.Image.FromStream(memStream);

the error happen at Image.FromStream() method.

I tried different ways and searched google without success. Also, I tried
Image.FromFile() where I got "out of memory exception" error.

Is window 2003 cause of this problem?
How I know if GDI+ is installed on window 2003?
Does the dell generated by visual studio .net include the GDI+ dll?

I would appreciate any help in this matter. Thanks

Any help to resolve the issue
I do not know why it does not work on test machine today. It works on my
machine and it worked on test machine previously. I appreciate any help to
resolve this problem. Thanks

Well, I'm sure that isn't the whole of the code which causes the error,
as that wouldn't compile.

However, you should really put the position of the stream back to 0
before passing it to Image.FromStream - you're asking it to read from a
stream which is already at the end at the moment.
 
I am sorry I had put the position back to 0 but I forgot to included in here.
For some reason it seems in window 2003 the byte stream (image) does not
work. I read that there is bug in GDI+ that can not handle 24 and 16 bit tif
files. I have 4bit gray scale tif file. Any idea? Thanks

That's why short but complete programs are so useful when you're trying
to demonstrate a problem. See

Does it work with other image formats? If so, that would suggest that
that's the problem.
