How do I render JPEG Data stored in char* buffer?

[On the Sparrow]

I have a 3rd party API that store compressed JPEG data in a char
buffer.ll

How do I convert it to either an System:rawing or somekind of format
that I can display in a Windows::Form?

It sounds like your using some managed language. Here's sample code for C#:

// Assuming char buffer contains jpeg header
MemoryStream memStream = new MemoryStream(jpeg_buffer, 0, buffer_size);
Bitmap bitmap = new Bitmap(memStream);
myPictureControl.BackgroundImage = bitmap;

Your question is platform specific, and has absolutely nothing to do
with the C++ language as defined by either ISO/IEC 14882:1998 or ISO/IEC
14882:2003.
