Use of SHBrowseForFolder() in wince 6.0

Hi.. A another less documented API is MSDN is use of SHBrowseForFolder() in wince 6.0

Several people have trouble getting to use SHBrowseForFolder().

Here is the code snippet which will create a Folder selection dialog in Wince 6.0

   1:     TCHAR psz_result[MAX_PATH];

2: LPMALLOC p_malloc = 0;

   3:     LPITEMIDLIST pidl;

4: BROWSEINFO bi;

   5:  

6: #ifdef UNDER_CE

   7:     #   define SHGetMalloc MySHGetMalloc

   8:     #   define SHBrowseForFolder MySHBrowseForFolder

   9:     #   define SHGetPathFromIDList MySHGetPathFromIDList

  10:  

  11:  

12: HMODULE ceshell_dll = LoadLibrary( _T("ceshell") );

  13:         if( !ceshell_dll ) return;

  14:  

  15:         HRESULT (WINAPI *SHGetMalloc)(LPMALLOC *) =

  16:             (HRESULT (WINAPI *)(LPMALLOC *))

  17:             GetProcAddress( ceshell_dll, _T("SHGetMalloc") );

  18:         LPITEMIDLIST (WINAPI *SHBrowseForFolder)(LPBROWSEINFO) =

  19:             (LPITEMIDLIST (WINAPI *)(LPBROWSEINFO))

  20:             GetProcAddress( ceshell_dll, _T("SHBrowseForFolder") );

  21:         BOOL (WINAPI *SHGetPathFromIDList)(LPCITEMIDLIST, LPTSTR) =

  22:             (BOOL (WINAPI *)(LPCITEMIDLIST, LPTSTR))

  23:             GetProcAddress( ceshell_dll, _T("SHGetPathFromIDList") );

  24:  

  25:         if( !SHGetMalloc || !SHBrowseForFolder || !SHGetPathFromIDList )

  26:         {

  27:             _tprintf( _T( "couldn't load SHBrowseForFolder API") );

  28:             FreeLibrary( ceshell_dll );

  29:             return;

  30:         }

  31:     #endif

  32:

  34:

36: bi.hwndOwner = NULL;

  37:         bi.lpszTitle = L"Select Folder to backup.";

  38:         bi.pszDisplayName = psz_result;

  39:         bi.ulFlags = BIF_EDITBOX;

  40:     #ifndef UNDER_CE

  41:         bi.ulFlags |= BIF_USENEWUI;

42: #endif

  43:  

  44:         if( (pidl = SHBrowseForFolder( &bi ) ) )

  45:             {

  46:                 SHGetPathFromIDList( pidl, psz_result );
