C++ (Cpp) IShellLibrary::Release Examples

Example #1

File: SearchFolder.cpp Project: Ippei-Murofushi/WindowsSDK7-Samples

// Create a shell item array object that can be accessed using IObjectCollection
// or IShellItemArray. IObjectCollection lets items be added or removed from the collection.
// For code that needs to run on Vista use SHCreateShellItemArrayFromIDLists()
HRESULT CreateShellItemArray(REFIID riid, void **ppv)
{
    *ppv = NULL;
    IShellLibrary *pLibrary;
    HRESULT hr = CoCreateInstance(CLSID_ShellLibrary, NULL, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pLibrary));
    if (SUCCEEDED(hr))
    {
        hr = pLibrary->GetFolders(LFF_ALLITEMS, riid, ppv);
        pLibrary->Release();
    }
    return hr;
}

Example #2

__inline HRESULT

                             REFIID riid, void **ppv)

    HRESULT hr = CoCreateInstance(CLSID_ShellLibrary, NULL,
                                  CLSCTX_INPROC_SERVER,
                                  IID_PPV_ARGS(&plib));
    if (SUCCEEDED(hr)) {
