好像GetPrinterDC()是CPrintDialog类的成员函数,可是我想打印的时候不出现打印对话框...可以做到么?Top

        用   API   试试:  
   
  '声明一串打印用   API  
      Private   Declare   Function   OpenPrinter   Lib   "winspool.drv"   Alias   _  
                    "OpenPrinterA"   (ByVal   pPrinterName   As   String,   phPrinter   As   Long,   _  
                      ByVal   pDefault   As   Long)   As   Long  
                       
      Private   Declare   Function   ClosePrinter   Lib   "winspool.drv"   (ByVal   _  
                      hPrinter   As   Long)   As   Long  
                       
      Private   Declare   Function   StartPagePrinter   Lib   "winspool.drv"   (ByVal   _  
                      hPrinter   As   Long)   As   Long
