                                                   222      '键(引号)

    procedure   TForm1.Edit1KeyDown(Sender:   TObject;   var   Key:   Word;  

          Shift:   TShiftState);  

    begin  

          if   key=VK_DELETE   then  

            key:=0;  

    end;  

    Delphi6.0,2000下通过Top

    于在keydown中屏蔽掉除数字外的所有键

    还应该允许Ctr+C/X/V,所以总结起来应该是:  

         procedure   TForm1.Edit1KeyPress(Sender:   TObject;   var   Key:   Char);  

    begin  

         if   not   (Key   in   ['0'..'9',   #3,   #22,   #24,   #8,   #13,   #45])   then   Key   :=   #0;  

    end;                                                

    procedure   TForm1.Edit1KeyPress(Sender:   TObject;   var   Key:   Char);  

    begin  

          if   (key>#57)   and   (key<#48)   then  

              key:=#0;  

    end;          

    我想你最好将你的例程写出来。  

            如果是像CKEN阁下说的那样,你要将按键事件屏蔽的话,实际上应该是直接赋值:  

            Key:=0;   

            (注意不是Key:=#0,因为这里的Key是Word类型,在keypress事件中,key的值是Char型,就要用“#”)  

            Good   luck

    在KeyDown里面就可以实现  

    if   key=vk_numpad0   then   (如果为小键盘的0键就干你想干的事情)  

    下面是小键盘的值
