关于得到 pidl （即：PathIDList）
的函数有：
SHGetSpecialFolderLocation(): 获得系统目录的位置
SHGetPathFromIDList (): 将 pidl 转化为文件夹路径
SHBrowseForFolder():
显示浏览文件夹对话框
SHBrowseForFolder()
是一个可以用于获取文件夹路径的Windows API
SHGetDesktopFolder()
函数原型:
下面以在VC中使用为例来获取桌面路径,代码如下:
LPITEMIDLIST ppidl;
char lpsbuf[255] = {0};
SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOP, &ppidl);
SHGetPathFromIDList(ppidl, lpsbuf);
MessageBox(lpsbuf);示例代码VC++
LPITEMIDLIST pidl;
LPMALLOC pShellMalloc;
char szDir[200] = {0};
if(SUCCEEDED(SHGetMalloc(&pShellMalloc)))
{
if(SUCCEEDED(SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOP, &pidl)))
{
<span style="white-space:pre"> </span>//如果成功返回true
SHGetPathFromIDList(pidl, szDir);
pShellMalloc->Free(pidl);
}
pShellMalloc->Release();
}
::MessageBox (NULL, szDir, "Path", MB_OK);void CDlgTestDlg::OnBnClickedOk()
{
LPITEMIDLIST pidl;
TCHAR szPath [MAX_PATH];
if(SUCCEEDED( SHGetSpecialFolderLocation ( NULL, CSIDL_FAVORITES, &pidl )))
{
if ( SHGetPathFromIDList ( pidl, szPath ))
{
CString sDisplayName;
SHFILEINFO sfi;
ZeroMemory(&sfi,sizeof(sfi));
UINT uFlags = SHGFI_PIDL | SHGFI_DISPLAYNAME;
SHGetFileInfo((LPCTSTR)pidl, 0, &sfi, sizeof(SHFILEINFO), uFlags);
sDisplayName = sfi.szDisplayName;
CString szDisplay;
szDisplay.Format(_T(" %s /n /n %s"),szPath, sDisplayName);
GetDlgItem(IDC_STATIC)->SetWindowText(szDisplay);
CoTaskMemFree(pidl); //free the resource
}
}
} SPDL： SHGetSpecialFolderLocation 获得系统目录的位置
