i was trying to load a bmp image to a picture box control, using the windows api, but i couldn't find anything on how to do that. Could someone explain it to me? I was also wondering if i could load jpeg and png images, too.

Is there a reason you are using Win32 API instead of a framework such as Qt?
i appreciate your suggestions, but i'm not asking about Qt or another framework.
-i have been working on win32 for weeks now and think its what i have been looking for. But if you insist that Qt is a better choice, i'll take a look at it.-
now do you have an answer for my first question?
Googling you can end up here
Don't know if there is explicitly a "Picture Box" in Win 32, but you can use any kind of window
thanks for your reply. do you know a way to load jpeg images too?
I was wondering why you were using Win32. I wasn't suggesting you to switch. That's none of my business.Quote:

As to your question, no: I have no idea. And the reason is because I don't tend to use Win32, because it's a pain in the ass. There are far better gui alternatives out there, which are C++ to boot, and not pure C.
if you are insane and like programming which is akin to dentistry, continue with the win api, if you like fast portable, easy to implement, native c++ coding, use fltk
why does everyone think win32 is pain? isn't it flexible enough to allow doing anything the windows OS allows? or is there another reason? and what does "being portable" mean?
and thanks C_ntua, you seem to be the only one who has answered my question
Because it takes a lot of code to do simple things and it isn't trivial.
Of course the Win32 API allows you to do all the OS allows, because that's the thing--it is the complete functionality the OS allows you to use. But it isn't easy.
Portable simply means it allows the code to work on multiple platforms. Win32 API obviously only works on Windows.
Qt, for example, works on Windows, Mac, Linux, Symbian, Maemo. And it's simpler to use.
Win32 is more flexible, but flexibility comes at a price of more complexity. There is a line you have to draw between flexible and ease to use. I would choose Qt or any other framework over Win32 at any time because 1) the api is C, which pretty much means that it's very inflexible and difficult to use, and 2) frameworks are far easier than the win32 api.
and can i use opengl and directx with frameworks?
It would be doubtful, though there may be solutions for OpenGL with Qt.
However, you must understand that if you're writing games, you don't need a Gui framework; you just need a window and manipulating effects via DirectX or OpenGL.
If you're after animations and such using hard acceleration, it is possible using existing methods and such within frameworks. There is no need for DirectX/OpenGL there.
thanks for the explanation.
but i'm still waiting for someone who knows win32 and is able to answer the main question
so perhaps you would have been better posting in the windows programming section. For what its worth FLTK has full openGL support
Forger has most of the information on his guide, theForger's Win32 API TutorialQuote:
