Loading an image in from a resource file

I'm using MSVC++ 2003 and am creating a windows forms application.
I want to load in an image from a resource file during runtime so that it can be used by a picturebox. It is fine if the image is added to the resources before compile/runtime.

I have absolutely no idea about resources. What I have tried though (successfully) is to add an image to my app.rc file. It then comes up in my resource view as IDB_BITMAP000 or something like that. How can I then use this in my program code to actually for example set the image of a picturebox to that image???

I don't think it's relevant, but the image(s) I am trying to load in are all bitmaps.

OR, is there a better way to do what I am trying to do other than using resources? Perhaps a different resource file type (not .rc but .resX or something like that...)??

As i said I have no idea and haven't programmed anything yet so I am open to all ideas!!

A second question:
How can I make it so that white JUST ON THAT IMAGE is treated as transparent. I tried setting the transparent colour on the picturebox object to white, but it didn't seem to work. Perhaps a stupid error on my part??

Thanks,

Philipp

Resource is a fine way to store images for your application, no doubt.

Have a look at this:LoadImage()

Windows Forms applications is Managed C++, a non-standard extension to C++.
Suggest you upgrade to at least 2005 to use Windows Form Applications to use the standard C++/CLI. Even so, LoadImage will most likely not work since it's meant for native.
Alternatively, you can just go for a native project.

A good advice for you: if you use Windows Forms, mention that you're using C++/CLI or Managed C++, since people will be confused otherwise.

Thanks,

That seems to open up a few more questions for me, because I didn't really understand what you were saying). What is managed C++, C++/CLI etc...

I have attached my two code files. Could you tell me if my environment is the one you thought I was programming in? I have no idea.:(

I've just been trying to program as usual in 'Form1.h'. 'Form1.cpp' was computer generated and I haven't touched that.

What is the difference between normal C++ and this?

PS What is a native project and how can I get it?

Maybe you've seen it... native C++, or the real C++, just C++. The typical Hello World program is:

Code:

---

int main()
{
    cout << "Hello World!";
    return 0;
}

---

Now. There is also an alternative to C++ using Microsoft's managed .NET Framework. You've probably heard of that, too. Microsoft made two versions. The first, 1.0 so to speak is called Managed C++. It's not standard, so it's locked in the Windows platform. This version is available in Visual Studio 2002 (.NET) & 2003 (also .NET)
The second version, C++/CLI as it's called is, or will be, a standard, thus can be used everywhere. Or will be anyway. Plus Managed C++ (v1.0) is deprecated. But 2.0 is available in Visual Studio 2005+.
So I suggest you upgrade if you want to use C++/CLI (2.0) or just go normal C++. Then you'll probably have to find some books and start with console applications.

Native projects are just not named Windows Forms Application. It's called Console Application or Win32 Application.
