Problem with Windows Forms

Aidan Gladwell (6)
I am having a problem with arguments for my Windows forms application.

I am using Visual basic. I have looked all over the place but couldn't find anything useful. I think that someone on here would have knowledge of Visual Basic enough to help me.

Variables:
1

3
 
Dim sLeft As String, sRight As String, sOperator As String
    Dim iLeft As Double, iRight As Double, iResult As Double
    Dim bLeft As Boolean


The code that doesn't work.

Private Sub AddOperator(sNewOperator As String)
        If bLeft Then
            sOperator = sNewOperator
            bLeft = False
        Else
            btnEquals_Click()
            sOperator = sNewOperator
            sRight = ""
            bLeft = False
        End If
    End Sub

This is the error message it gives me when I hover over the item:
Argument not specified for parameter 'sender' of 'Private Sub btnEquals_Click(sender As Object, e As System.EventArgs)'.


Here is the code in "btnEquals_Click()":

Private Sub btnEquals_Click(sender As Object, e As EventArgs)
        If sLeft <> "" And sRight = "" And sOperator <> "" Then
            sRight = sLeft
        End If

        If sLeft <> "" And sRight <> "" And sOperator <> "" Then
            iLeft = sLeft
            iRight = sRight

            Select Case sOperator
                Case "+"
                    iResult = iLeft + iRight
                Case "-"
                    iResult = iLeft - iRight
                Case "/"
                    iResult = iLeft / iRight
                Case "*"
                    iResult = iLeft * iRight
            End Select

            tbResult.Text = iResult

            sLeft = iResult
            sRight = ""
            bLeft = True
        End If
    End Sub


The code works when I set the code like this:
Private Sub btnEquals_Click()
But it doesn't do anything.

How can I get btnEquals_Click() to work?

you have to pass sender to btnEquals_Click

And how would I do that?

i dont know. i have never used and hopefully never will use vb. but your error says that it expects something to be passed to it and you arent doing that
