目录浏览对话框

[i_love_star]

如何在出现对话框后自动定位到某一目录(如自动定位到a:\b\c)?
我使用的是SHBrowseForFolder（）
SHGetPathFromIDList()

参考代码：

// Macros for interface casts
#ifdef __cplusplus
#define IID_PPV_ARG(IType, ppType) IID_##IType, reinterpret_cast(static_cast(ppType))
#else
#define IID_PPV_ARG(IType, ppType) &IID_##IType, (void**)(ppType)
#endif

// Retrieves the UIObject interface for the specified full PIDL
STDAPI SHGetUIObjectFromFullPIDL(LPCITEMIDLIST pidl, HWND hwnd, REFIID riid, void **ppv)
{
LPCITEMIDLIST pidlChild;
IShellFolder* psf;

*ppv = NULL;

HRESULT hr = SHBindToParent(pidl, IID_PPV_ARG(IShellFolder, &psf), &pidlChild);
if (SUCCEEDED(hr))
{
hr = psf->GetUIObjectOf(hwnd, 1, &pidlChild, riid, NULL, ppv);
psf->Release();
}
return hr;
}

#define ILSkip(pidl, cb) ((LPITEMIDLIST)(((BYTE*)(pidl))+cb))
#define ILNext(pidl) ILSkip(pidl, (pidl)->mkid.cb)

HRESULT SHILClone(LPCITEMIDLIST pidl, LPITEMIDLIST *ppidl)
{
DWORD cbTotal = 0;

if (pidl)
{
LPCITEMIDLIST pidl_temp = pidl;
cbTotal += sizeof (pidl_temp->mkid.cb);

while (pidl_temp->mkid.cb)
{
cbTotal += pidl_temp->mkid.cb;
pidl_temp += ILNext (pidl_temp);
}
}

*ppidl = (LPITEMIDLIST)CoTaskMemAlloc(cbTotal);

if (*ppidl)
CopyMemory(*ppidl, pidl, cbTotal);

return *ppidl ? S_OK: E_OUTOFMEMORY;
}

// Get the target PIDL for a folder PIDL. This deals with cases where a folder
// is an alias to a real folder, folder shortcuts, etc.
STDAPI SHGetTargetFolderIDList(LPCITEMIDLIST pidlFolder, LPITEMIDLIST *ppidl)
{
IShellLink *psl;

*ppidl = NULL;

HRESULT hr = SHGetUIObjectFromFullPIDL(pidlFolder, NULL, IID_PPV_ARG(IShellLink, &psl));

if (SUCCEEDED(hr))
{
hr = psl->GetIDList(ppidl);
psl->Release();
}

// It's not a folder shortcut so get the PIDL normally.
if (FAILED(hr))
hr = SHILClone(pidlFolder, ppidl);

return hr;
}

// Get the target folder for a folder PIDL. This deals with cases where a folder
// is an alias to a real folder, folder shortcuts, the My Documents folder, etc.
STDAPI SHGetTargetFolderPath(LPCITEMIDLIST pidlFolder, LPWSTR pszPath, UINT cchPath)
{
LPITEMIDLIST pidlTarget;

*pszPath = 0;

HRESULT hr = SHGetTargetFolderIDList(pidlFolder, &pidlTarget);

if (SUCCEEDED(hr))
{
SHGetPathFromIDListW(pidlTarget, pszPath); // Make sure it is a path
CoTaskMemFree(pidlTarget);
}

return *pszPath ? S_OK : E_FAIL;
}

platform SDK和DirectX SDK冲突，无法使用2楼方法
还有其他方法吗?
