No overload for ... matches delegate 'MouseEventHandler'

Erroneous output

    private void ChangeMinLevel()
    {
        try
        {
            Waterfall1.Levels.Axis.Min = tb_MinLevel.Value;
        }
        catch (Exception ex)
        {
            PostErrors_ThreadSafe(ex.ToString(), "ChangeMinLevel", "", true);
        }
    }

Expected output

    private void ChangeMaxLevel(object sender, MouseEventArgs e)
    {
        try
        {
            Waterfall1.Levels.Axis.Max = tb_MaxLevel.Value;
        }
        catch (Exception ex)
        {
            PostErrors_ThreadSafe(ex.ToString(), "ChangeMaxLevel", "", true);
        }
    }

Thanks for the report, could you post the input code please? I tried the following but it seemed to work fine:

Private Sub ChangeMaxLevel(ByVal sender As Object, ByVal e As MouseEventArgs)
    Try
        Waterfall1.Levels.Axis.Max = tb_MaxLevel.Value
    Catch ex As Exception
        PostErrors_ThreadSafe(ex.ToString, "ChangeMaxLevel", "", True)
    End Try
End Sub

I notice you posted two different methods in your report, did one work and the other not work? If so, seeing both might speed up diagnosis of the issue. Thanks!

Found a repro

Partial Public Class Form1
    Private Sub Form1_MouseClick() Handles Me.MouseClick
    End Sub

    Public Sub Init()
        AddHandler Me.MouseClick, AddressOf Form1_MouseClick
    End Sub

    Public Sub Other()
        Form1_MouseClick()
    End Sub
End Class

Notes:

• The only compilable forms in VB are to specify all parameters, or none. You can't specify just some.
• The correct output in these cases is to add the event handler as a lambda which throws away the args (checked in DotPeek)
• Removing a handler like this generates a warning and has no compile time effect since the lambda is a different instance. Converting to use its own lambda, then prefixing with a #warning directive would be slightly better in terms of allowing the user to see and deal with the issue in their own time

Please retest. Should be fixed by #537
