What does this return?

Well, adding the tray icon works fine. The icon shows up and can be removed just fine.

The debugger doesn't seem to want to work. I might have to try a different IDE and see if it will make the compiler build the file with debugging info. When trying to get the debugger to work, this warning started to come up and it is now coming up all the time when I build my project.

<quote>Project : Win32 Application
Compiler : GNU GCC Compiler (called directly)
Directory : C:\Documents and Settings\John\Desktop\derp\

This is the code it is pointing to:

                      "WindowClass1",    // name of the window class<br />
                      "Our First Windowed Program",   // title of the window<br />
                      WS_OVERLAPPEDWINDOW,    // window style<br />

                      NULL);    // used with multiple windows, NULL

The last NULL in the list is the line the compiler points to. Could this warning have an affect on the program not detecting when I click the icon?

If the compiler says "undeclared identifier" it means it can't find it. There are two possibilities:
1. A missing header file.
2. The identifies name is wrong or it's in a namespace and you haven't qualified the name with it or put in a using statement to import it.

Knock number two on the head by adding no_namespace after the #import. i.e.

#import "Voodoo.tlb" no_namespace

This tells the compiler not to use namespaces.

When the component is authored the interface is probably described in an IDL or ODL file. If so, when it is compiled with MIDL a type library and some C++ header files are produced. If these files are distributed you can use these for C++.

If the interfaces are IDispatch based you could use the library without any type information, but this hard to describe and not the best approach in C++ anyway.

How are you importing your tlb file?
Remember that unless you specify it, you will need to specify the namepace scope. So:

#import "somelibrary.tlb" named_guids
..
..
HRESULT hr = CoCreateInstance(SOMELIBRARYLIB::CLS_ITest, NULL,             
                              CLSCTX_ALL,
                              SOMELIBRARYLIB::IID_ITest, (void**)&pTest);
..
..

Notice the namepace scope.

There is no direct equivalent. Try calling InternetOpenUrl() followed by InternetReadFile().

produced hits where the second one listed is titled "Building an Internet Browser Using the Win32 Internet Functions". The following sample code is contained in that article which you could have easily found for yourself.

from the sample the "char" array named "buffer" would contain the HTML. In C/C++ char arrays are "strings" so basicaly you can copy that buffer into the edit control.

I don't know why you are doing this in C++ from a VB background but things are very different in C/C++ from VB. There are so many different ways to get a char array into a windows edit control depending on "how" you are developing your solution. If using MFC you have classes that you are using that simplify these operations. If not you must send messages to windows controls to interact with them. This is a small part of the fundamental knowledge needed for windows development in C/C++. Asking questions in a forum about using API's when you don't have basic C/C++ experience will be a very slow and tiresome process.

That means you have not included a required header file. That is basic C/C++ knowledge. A perfect example of what I am telling you. If you are going to develop using VC++ you better go back to the start and learn some basics, jumping into an actual project when you don't even know about including header files is completely insane.
