Shell里面(Explorer)的右键菜单中,怎样得到所选文件名?

[rayyang2000]

如题.我在IContextMenu::InvokeCommand中想得到右键所选的文件名,以便交给其他程序处理.但是怎样才能得到文件名呢?谢谢!

std::list<string> m_listFileNames;

STDMETHODIMP CJexContextMenu::Initialize(LPCITEMIDLIST pidlFolder, LPDATAOBJECT lpdobj, HKEY hkeyProgID)
{
HRESULT hres = E_FAIL;
FORMATETC fmte = { CF_HDROP, NULL, DVASPECT_CONTENT, -1, TYMED_HGLOBAL};
STGMEDIUM medium;
int nFileCount = 0, i;
_TCHAR strFilePath[MAX_PATH];

// No data object
if (lpdobj == NULL)
return E_FAIL;

// Use the given IDataObject to get a list of filenames (CF_HDROP).
hres = lpdobj->GetData(&fmte, &medium);

if (FAILED(hres))
return E_FAIL;

// Make sure HDROP contains at least one file.
if ((nFileCount = DragQueryFile((HDROP)medium.hGlobal, (UINT)(-1), NULL, 0)) >= 1)
{
// Loop through all the files that were selected.
for (i = 0; i < nFileCount; i++)
{
DragQueryFile((HDROP)medium.hGlobal, i, strFilePath, MAX_PATH);
// If the file name is a directory, make sure it has a backslash at the end.
if (::GetFileAttributes(strFilePath) & FILE_ATTRIBUTE_DIRECTORY)
{
int nLen = _tcslen(strFilePath);
if (strFilePath[nLen-1] != _T('\\'))
{
_tcscat(strFilePath, _T("\\"));
}
}
// Add the file name to the end of the list.
m_listFileNames.push_back(strFilePath);
}
hres = S_OK;
}
else
hres = E_FAIL;

// Release the data.
ReleaseStgMedium (&medium);

return hres;
}

STDMETHODIMP CJexContextMenu::InvokeCommand(LPCMINVOKECOMMANDINFO lpici)
{
_TCHAR* pStrClipboardText = NULL, strTempFileNameBuff[MAX_PATH + 50];
_TCHAR *pCurrent = NULL, *pLast = NULL;
BOOLEAN bMakeCStyleString = ((GetKeyState(VK_CONTROL) & 0x8000) != 0);
BOOLEAN bMakeShortPath = ((GetKeyState(VK_SHIFT) & 0x8000) != 0);
int nFileCount = 0, i;
CString strPath;

if (!HIWORD(lpici->lpVerb))
{
UINT nCmd = LOWORD(lpici->lpVerb);
CString strFilePath = m_listFileNames.front().data();
AfxMessageBox(strFilePath);
break;
}
return S_OK;
}

可以通过IPersistFile接口得到文件名的。
