单项选择题
在窗体上从左到右有Text1、Text2两个文本框(见图),要求运行程序时在Text1中输入—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—个数,则光标移到Text2中;否则光标不动,并弹出对话框“分数错”。下面程序中正确的是()。
A.Private Sub Text1_KeyPress(KeyAscii As Intege IfKeyAscii=13 Then '回车符的ASCII码是13 a=Va1(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 Intege IfKeyAscii=13 Then '回车符的ASCII码是13 a=Val(Text1) Ifa>=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 Intege IfKeyAscii=13 Then '回车符的ASCII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 Intege IfKeyAscii=13 Then '回车符的ASCII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
