在窗体上从左到右有Text1、Text2两个文本框（见下图）

要求程序运行时,在Text1中输入1个分数后按回车键,则判断分数合法性,若分数为0—100的1个数,则光标移到Text2中,否则光标不动,并弹出对话框显示"分数错"。下面程序中正确的是【 】

A．Private Sub Text1_KeyPress( KeyAscii As Integer) If KeyAscii=13 Then 回车符的ASCII码是13a=Val(Text1)If a>；0 Or a<=100 ThenText2.SetFocusE1seTextl.SetFocus：MsgBOX("分数错")End IfEnd IfEnd Sub

B．Private Sub Textl_KeyPress(KeyAscii As Integer)If KeyAscii=13 Then 回车符的ASCII码是13a=val(Textl)If a>=0 And a<=100 ThenTextl.SetFocusE1seText2.SetFocus：MsgBOX("分数错")End IfEnd IfEnd Sub

C．Private Sub Textl_KeyPress(KeyAscii As Integer)If KeyAscii=13 Then 回车符的ASCII码是13a=val(Textl)If a<0 And a>100 ThenText2.SetFoeusElseTextl.SetFocus：MsgBOX("分数错")End IfEnd IfEnd Sub

D．Private Sub Text1l一Key Press (Key Ascii As Integer)If KeyAscii=13 Then 回车符的ASCII码是13a=Val(Text1)If a>=0 And a<=100 ThenText2.SetFocusElseText1.Set Focus：Msgbox("分数错")End IfEnd IfEnd Sub
