Well, normal windows GDI functions can ONLY read in bitmaps with palettes, so normally, this wouldn't be possible unless you wanted to cod ehte reading/writing yourself, or you got a 3rd party graphics library.

However, with GDI+, MS has added support for the JPG format. See

http://www.codeguru.com/gdi/GDIPlus.html

for general information on how to get this working for you. Note that you'll need to make small changes to the example code to get it to compile outside of MSVC (mainly changing how you tell the compiler to link the necessary library) but this should put you on the right track, anyway.

Someone asked this before.

If you search through the threads you should be able to find links two more jpg libaries.

thanks anyway
but i don't want to use a dll ,it just not include in the windows system.i am finding a diffucult way,a classical method to do this.
thanks... maybe some api can do this such as SetDIBitsToDevice,
StretchDIBits,OleLoadPicture....

There IS none. GDI+ is the closest to a "classical method" there is -- this actually DOES ship on newer MS OS's, but if you're using traditional WinAPI GDI commands, the one and only format you can read without coding yourself is an paletted BMP.

GDI+ was specifically designed, among other things, to address this issue.
