在VC中做一个选择文件夹的对话框

VC中没有现成的函数来选择一个文件夹，但这是经常会用到的，怎么办？

自动动手，丰衣足食！

使用SHBrowseForFolder，代码如下：

#include <Shlobj.h>

int SelFolder(HWND hParent, CString &strFolder)

{

strFolder.Empty();

LPMALLOC lpMalloc;

if (::SHGetMalloc(&lpMalloc) != NOERROR) return 0;

char szDisplayName[_MAX_PATH];

char szBuffer[_MAX_PATH];

BROWSEINFO browseInfo;

browseInfo.hwndOwner = hParent;

browseInfo.pidlRoot = NULL; // set root at Desktop

browseInfo.pszDisplayName = szDisplayName;

browseInfo.lpszTitle = "Select a folder";

browseInfo.ulFlags = BIF_RETURNFSANCESTORS|BIF_RETURNONLYFSDIRS;

browseInfo.lpfn = NULL;

browseInfo.lParam = 0;

LPITEMIDLIST lpItemIDList;

if ((lpItemIDList = ::SHBrowseForFolder(&browseInfo)) != NULL)

{

// Get the path of the selected folder from the item ID list.

if (::SHGetPathFromIDList(lpItemIDList, szBuffer))

{

// At this point, szBuffer contains the path the user chose.

if (szBuffer[0] == '\0') return 0;

// We have a path in szBuffer! Return it.

strFolder = szBuffer;

return 1;

}

else return 1; // strResult is empty

lpMalloc->Free(lpItemIDList);

lpMalloc->Release();

}

return 1;

}
