单选题

在窗体上从左到右有Text1、Text2两个文本框（见图），要求程序运行时，在Text1中输入1个分数后按回车键，则判断分数的合法性，若分数为0~100中的1个数，周围光标移到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( )

Question

A. Private Sub Text1__KeyPress(KeyAscii AS Integer)
If KeyAscii=13 Then ‘回车符的ACSII码是13
a=Val(Text1)
If a>=0 or a<=100 Then
Text2.SetFocus
Else
Text1. SetFocus ; MsgBox(“分数错”)
End If
End If
End Sub

B. Private Sub Text1__KeyPress(KeyAscii AS Integer)
If KeyAscii=13 Then ‘回车符的ACSII码是13
a=Val(Text1)
If a>=0 And a<=100 Then
Text1.SetFocus
Else
Text2. SetFocus ; MsgBox(“分数错”)
End If
End If
End Sub

C. Private Sub Text1__KeyPress(KeyAscii AS Integer)
If KeyAscii=13 Then ‘回车符的ACSII码是13
a=Val(Text1)
If a<0 And a>100 Then
Text2.SetFocus
Else
Text1. SetFocus ; MsgBox(“分数错”)
End If
End If
End Sub

D. Private Sub Text1__KeyPress(KeyAscii AS Integer)
If KeyAscii=13 Then ‘回车符的ACSII码是13
a=Val(Text1)
If a>=0 And a<=100 Then
Text2.SetFocus
Else
Text1. SetFocus ; MsgBox(“分数错”)
End If
End If
End Sub
