Bitmap(stream) and ArgumentException

[Federico Del Bene]

I have this piece of code perfectly working on the full framework:

-----------------
byte[] b = binaryReader.ReadBytes(145206);
MemoryStream ms = new MemoryStream(b);
ms.Seek(0,System.IO.SeekOrigin.Begin);
System.Drawing.Bitmap bm = new System.Drawing.Bitmap(ms);
-----------------

But on the compact one it generates an ArgumentException on the last line.
Any idea about the problem?

Thanks,
Federico Del Bene

Hi Federico,

The problem might be that Bitmap on Pocket PC have different headers than
bitmap on PC.
You can try to see the different bitmap header types on this page:

What is the stream format? BMP? JPG? PNG? What kind of device? Do you have
Service Pack 3 installed?

I just found out that it is a problem of the Pocket PC 2003 First Edition
Emulator. In the Second Edition's one all work fine.

Btw, it was a BMP, and the header was the same on the PocketPC and on the
PC.
