    Can't see IActiveDesktop?

    I'm fiddling with COM and as a first program I thought I'd have a fiddle with IActiveDesktop. According to MSDN I need to include shlobj.h, which I do, but this code fails to compile:

    Code:
    #include <iostream>
    #include <windows.h>
    #include <shobjidl.h>
    #include <shlguid.h>
    #include <shlobj.h>
    
    using namespace std;
    
    int main(int argc, char *argv[])
    {
        HRESULT hr = 0;
        IShellLink *pISL;
        IActiveDesktop *pIAD;
    
        CoInitialize(0);
    
        hr = CoCreateInstance(CLSID_ShellLink,
                              NULL, // no aggregation
                              CLSCTX_INPROC_SERVER,
                              IID_IShellLink,
                              (void **) &pISL);
    
        if (SUCCEEDED(hr))
        {
    
            pISL->Release();
        }
        else
        {
            CoUninitialize();
            cout << "Error creating COM object [" << hr << "]" << endl;
            return -1;
        }
    
        CoUninitialize();
        return 0;
    }
    (I was looking at IShellLink too).

    Errors:

    Code:
    c:\Documents and Settings\lee\Desktop\COMStuff\COMStuff.cpp(12) : error C2065: 'IActiveDesktop' : undeclared identifier
    c:\Documents and Settings\lee\Desktop\COMStuff\COMStuff.cpp(12) : error C2065: 'pIAD' : undeclared identifier
    Am I missing something here? If I right click IActiveDesktop and "Go to definition" it takes me to shlobj.h so I know it's there.
    Good class architecture is not like a Swiss Army Knife; it should be more like a well balanced throwing knife.

    It's ok I had a search for IActiveDesktop on koders and found that some software used wininet.h too. Why the hell doesn't MSDN say that? Or any of the tutorials you read?

    Stoopid world.

    EDIT: While on the subject, are there any good tutorials out there? The best one I've found was on codeproject and the MSDN docs are quite easy to follow. I just thought there would have been more articles on it.
