Platform: .NET 2.0

Environment: Windows Vista (32-bit)

Hi,

I'm using VB.Net Add-On + WinForm Control and I have a class with a Default Property:


Public Class ccolTest

    Inherits System.Collections.CollectionBase
        
    Public Property subcolTest As ccolTest
        
    Default Public Overloads Property Item(ByVal index As Integer) As String
        Get
            Return List(index)
        End Get
        Set(ByVal Value As String)
            List(index) = Value
        End Set
    End Property

End Class

When use a variable of this type the intelliprompt and intellisense works fine after ( char:


    Sub MySub()
        Dim dpTestObj As New ccolTest
        dpTestObj( '<----trigger
    End Sub

But if I have a property of this type the editor don't show the intelliprompt and shows a wrong member-list:


    Sub MySub()
        Dim dpTestObj As New ccolTest
        dpTestObj.subcolTest( '<---- do not trigger 
        dpTestObj.subcolTest(0). '<---- shows wrong member-list
    End Sub

Thanks in advance.

Hi Sergio,

Thanks for reporting this. We did some investigation and found that we're running into issues here due to ambiguity with the VB language on how indexers, methods, and arrays all use parenthesis so it's tricky to know what a particular syntax is attempting to reference, unlike in C# where it's clear.

In this particular scenario, it looks like we'd need to do a lot of internal restructuring to resolve the ambiguity and handle it properly. We are going to be starting a reworking of our internal context building engine in the next several weeks now that we have begun work on the WPF/Silverlight version of the add-on. I'm writing down this scenario on our TODO list to make sure we handle it.

I did the same test with an older version (v4.0.0282) of the SintaxEditor, and in this version the problem doesnt occur.

Yes but that was probably an unintended side effect of other features not working correctly yet, that we have enhanced since then.

Hello, yes the WinForms version of SyntaxEditor still has old resolver code where one of those examples doesn't work. The examples above all work in our newer codebase in the WPF version. We are going to look into possibly backporting our WPF SyntaxEditor codebase back to WinForms so that everything is on the same improved codebase.
