Function 如何在函数中使用组合框值并选择大小写？

我正在写一个程序，让用户选择他们的星座和另一个人的星座。一旦出现这种情况，我想用这些符号来衡量它们的兼容性，其结果分为三类。我有一个程序，用户可以选择这两个符号，程序可以把它们吐出来，告诉用户他们选择了什么（我不需要这个消息框，我只是检查我的代码是否正常工作）。我遇到的问题是使用“兼容性”函数和select case，我不知道我是否需要声明新变量，或者如果我将它们公开，它们是否会工作。显然，我的代码不起作用，否则我就不会寻求帮助。对于所选的情况，到目前为止，我只为白羊座准备了一个，但所有12个星座都需要这样做

以下是新代码：

公开课表格1

Public Sub btnBegin_Click(sender As Object, e As EventArgs) Handles btnBegin.Click
    lblMySign.Visible = True
    lblYourSign.Visible = True
    cbMySign.Visible = True
    cbYourSign.Visible = True
    btnBegin.Visible = False

    Dim MySign As String
    Dim YourSign As String

    MySign = cbMySign.Text
    YourSign = cbYourSign.Text

    Call Compatibility(Me.cbMySign.Text, Me.cbYourSign.Text)
End Sub

Public Sub cbMySign_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cbMySign.SelectedIndexChanged

End Sub

Public Sub cbYourSign_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cbYourSign.SelectedIndexChanged
    'Dim MySign As String
    'Dim YourSign As String

    'MySign = cbMySign.Text
    'YourSign = cbYourSign.Text


End Sub
Function Compatibility(cbMySign As String, cbYourSign As String) As String
    Dim strCompat As String

    Select Case cbMySign
        Case "Aries"
            Select Case cbYourSign
                Case "Taurus", "Cancer", "Virgo", "Pisces"
                    strCompat = "NC"
                Case "Gemini", "Libra", "Scorpio", "Capricorn", "Aquarius"
                    strCompat = "N"
                Case "Aries", "Leo", "Sagittarius"
                    strCompat = "C"
            End Select
    End Select

    If strCompat = "NC" Then
        MsgBox("You're not compatible")
    ElseIf strCompat = "N" Then
        MsgBox("You're neutral")
    Else
        MsgBox("You're compatible")
    End If
End Function

课程结束时下午3:10更新 很抱歉回复太晚，需要参加一系列会议

我试着运行你的全部代码，复制粘贴并运行，它工作得非常完美

我试过：

我的星座是白羊座 你的星座=处女座

结果：“你不兼容”

我的问题是，当你点击BtnBegin时，它什么时候会再次可见

lblMySign.Visible = True 
lblYourSign.Visible = True 
cbMySign.Visible = True 
cbYourSign.Visible = True 
btnBegin.Visible = False '--- here it is?

我想您需要在单击cbMySign或cbYourSign后重置此项
