Question

在调用WINDOWS“浏览文件夹”对话框时，如何初始化选择"c:\windows"路径？

Answer 1

用写个回调函数。微软例子代码：http://support.microsoft.com/kb/179378#define STRICT
#include <windows.h>
#include <shlobj.h>INT CALLBACK BrowseCallbackProc(HWND hwnd, 
                                UINT uMsg,
                                LPARAM lp, 
                                LPARAM pData) 
{
   TCHAR szDir[MAX_PATH];   switch(uMsg) 
   {
   case BFFM_INITIALIZED: 
      if (GetCurrentDirectory(sizeof(szDir)/sizeof(TCHAR), szDir))
      {
         // WParam is TRUE since you are passing a path.
         // It would be FALSE if you were passing a pidl.
         SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM)szDir);
      }
      break;   case BFFM_SELCHANGED: 
      // Set the status window to the currently selected path.
      if (SHGetPathFromIDList((LPITEMIDLIST) lp ,szDir))
      {
         SendMessage(hwnd,BFFM_SETSTATUSTEXT,0,(LPARAM)szDir);
      }
      break;
   }
   return 0;
}
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR lpszCmdLine,
                     int nCmdShow)
{
   BROWSEINFO bi;
   TCHAR szDir[MAX_PATH];
   LPITEMIDLIST pidl;
   LPMALLOC pMalloc;   if (SUCCEEDED(SHGetMalloc(&pMalloc)))
   {
      ZeroMemory(&bi,sizeof(bi));
      bi.hwndOwner = NULL;
      bi.pszDisplayName = 0;
      bi.pidlRoot = 0;
      bi.ulFlags = BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT;
      bi.lpfn = BrowseCallbackProc;      pidl = SHBrowseForFolder(&bi); 
      if (pidl) 
      { 
          // 
          // Other code omited 
          // 
          pMalloc->lpVtbl->Free(pMalloc,pidl); 
      } 
      pMalloc->lpVtbl->Release(pMalloc);
   }
   return 0;
}

Answer 2

TCHAR szDir[100];
GetWindowsDirectory(szDir, 100);
