我要创建一个ShellItem Windows帮助和Windows运行...

我有这个

Run {2559a1f3-21d7-11d4-bdaf-00c04f60b9f0}

从http://www.sevenforums.com/tutorials/110919-clsid-key-list-windows-7-a.html

我试过了

IShellFolder* desk = NULL;
HRESULT hr =SHGetDesktopFolder(&desk);
LPITEMIDLIST pidl2=NULL;
            ULONG cbEaten;
            DWORD dwAttribs = 0 ;

            hr = desk->ParseDisplayName(NULL,
                                         NULL,
                                         L"::{2559A1F1-21D7-11D4-BDAF-00C04F60B9F0}",
                                     &cbEaten,  // This can be NULL
                                         &pidl2,
                                         &dwAttribs);

它返回OK,但Null作为pidl2

可你们给我一些帮助吗?

Answer 1:

ParseDisplayName应该能够解析它,如果你通过“壳::: {2559a1f3-21d7-11d4-BDAF-00c04f60b9f0}”但我想这是不是真的,你想要什么。

ParseDisplayName能够解析一些:: {} CLSID路径,但我认为它被限制在一个非常有限CSIDL_的*特殊文件夹。 SHSimpleIDListFromPath能够解析它。

如果你真的想与ParseDisplayName解析它,你可以尝试效仿SHSimpleIDListFromPath:

class EmptyFileSystemBindData : public IFileSystemBindData {
public:
    STDMETHODIMP QueryInterface(REFIID riid, void **ppv)
    {
        if (riid == IID_IUnknown || riid == IID_IFileSystemBindData) {
            *ppv = static_cast<IUnknown*>(this);
            AddRef();
            return S_OK;
        }
        *ppv = NULL; return E_NOINTERFACE;
    }
    STDMETHODIMP_(ULONG) AddRef() { return 2; }
    STDMETHODIMP_(ULONG) Release() { return 1; }
    STDMETHODIMP SetFindData(const WIN32_FIND_DATAW *pfd) 
    {
        return S_OK;
    }
    STDMETHODIMP GetFindData(WIN32_FIND_DATAW *pfd)
    {
        ZeroMemory(pfd,sizeof(WIN32_FIND_DATAW));
        return S_OK;
    }
};

LPITEMIDLIST pidl2=NULL;
HRESULT hr;
IShellFolder*psf;
IBindCtx*pbc;
hr = CreateBindCtx(0,&pbc);
EmptyFileSystemBindData efsbd;
if (SUCCEEDED(hr))
{
    BIND_OPTS bo = {sizeof(bo)};
    bo.grfMode = STGM_CREATE;
    hr = pbc->RegisterObjectParam(STR_FILE_SYS_BIND_DATA,&efsbd);
    if (SUCCEEDED(hr) && 0==pbc->SetBindOptions(&bo))
    {
        hr = SHGetDesktopFolder(&psf);
        if (SUCCEEDED(hr))
        {
            hr = psf->ParseDisplayName(0,pbc,L"::{2559a1f3-21d7-11d4-bdaf-00c04f60b9f0}",0,&pidl2,0);
            if (SUCCEEDED(hr))
            {
                OutputDebugStringA("parsed ok\n");
                ILFree(pidl2);
            }
            psf->Release();
        }
    }
    pbc->Release();
}
