[Mono-devel-list] Re: [Mono-list] IStream implementation on Win32 for System.Drawing.Image.InitFromStream

Hi,

Please tell the version number of Mono and the name and version number of
operating system you are using along with the complete stack trace printed
when the exception is thrown.

This exception message seems to be thrown only in gdipFunctions.cs for
unmanaged error code so it may be a missing functionality in libgdiplus
because I was able to generate resource file on Windows using Mono's
resgen.exe.

If the same error occurs using the latest sources build from SVN please file
a bug report at http://bugzilla.ximian.com/.

Hello Kornél,

many thanks for your tip.

If I use the tool of resgen in mono/libgdiplus to generate resource
file from the following resx file, I always got the exception:
"Feature not implemented". This exception will be throwed from the
method of GdipLoadImageFromStream of image.cs in the libgdiplus. I am
still wondering why I got the exception.

Best regards,
Huaiyang
