The problem here seems to be that CFbsBitmap::Externalize() doesn't write a .mbm file, like you seem to expect,
but some internal format that only CFbsBitmap::Internalize understand. (or someone reverse enginering it).

You need to rethink your file strategy. Externalize/Internalize is mainly used when you want to pack several types of data into one file, its not ment to write any particular file standard, just any data that Internalize would need to recreate the object.

If you want to write several of your CFbsBitmap(s) in a .mbm, take a look at the CFbsBitmap::StoreL function instead.
If you only want one, why not use CFbsBitmap::Save?
If you want to create your own fileformat, go with Externalize/Internalize

check the class documentation and headers for the bitmap class, it should have internalize & externalize functions for internalizing & externalizing the image.

Problem is that I need store CFbsBitmap to file through stream

But result of
RWriteStream::Create(RFS, filename, iFlags)
RWriteStream::Open(RFS, filename, iFlags)
CFbsBitmap::ExternalizeL(RWriteStream)

is not save like
CFbsBitmap::Save(filename)

So please if I start
RWriteStream::Create(RFS, filename, iFlags)
RWriteStream::Open(RFS, filename, iFlags)
what next? how to save CFbsBitmap to stream

after for test I will use
CFbsBitmap::Load(filename)

Thanks

Hi

What is the excat problem that you are having ? any erro notes. I have used dictionary stored succesfully with bitmaps, so maybe you should try them as well.
