用VB编写一个控制台，定义两个变量X,Y，从键盘上输入x,y，由程序计算值并输出结果

Answer 1

加两个编辑框就可以了。
Private Sub Command1_Click()
If Text2.Text = "+" Then
Command1.Caption = "结果" & Str(Int(Text1.Text) + Int(Text1.Text))
ElseIf Text2.Text = "-" Then
Command1.Caption = "结果" & Str(Int(Text1.Text) - Int(Text1.Text))
ElseIf Text2.Text = "*" Then
Command1.Caption = "结果" & Str(Int(Text1.Text) * Int(Text1.Text))
ElseIf Text2.Text = "/" Then
Command1.Caption = "结果" & Str(Int(Text1.Text) / Int(Text1.Text))
Else
MsgBox "运算符号输入错误！", 64, "提示！"
Exit Sub
End If

End Sub
