流转很久源的代码



BOOL CopenDsnTreeDlg::enumNetname(LPNETRESOURCE lpNetRC_p)

DWORD dwScope = RESOURCE_GLOBALNET ;

if( dwResult != NO_ERROR )
return FALSE;
DWORD dwBuffer = 16384 ; // 16K is reasonable size
DWORD dwEntries = 0xFFFFFFFF ; // enumerate all possible entries
LPNETRESOURCE lpnrLocal = 0;
do
{
lpnrLocal = (LPNETRESOURCE) GlobalAlloc( GPTR, dwBuffer ) ;
dwResult = WNetEnumResource(hNet,&dwEntries,lpnrLocal,&dwBuffer) ;
if( dwResult == NO_ERROR )
{
for( DWORD i = 0 ; i < dwEntries ; i++ )
{
CString nsname = lpnrLocal[i].lpRemoteName;
if(lpnrLocal[i].dwDisplayType == RESOURCEDISPLAYTYPE_SERVER)//计算机名
{
nsname=nsname.Right(nsname.GetLength()-2);
m_enumcomputername.AddTail(nsname);

if( !enumNetname( &lpnrLocal[i]) )
return FALSE;
}
}
else if( dwResult != ERROR_NO_MORE_ITEMS )
