Ingo talks about Webservices and Remoting
Last night I went to a presentation of Ingo Rammer about Remoting vs. Webservices, in Brussels, organised by the Belgian .NET Usergroup (BENUG) and sponsored by Ineta. The first part of the presentation was about Webservices (the usual stuff), and the second part was about Remoting (which was the reason I think, that people wanted to see this presentation because Ingo is known as a Remoting guy). Ingo did a nice job explaining the Remoting basics: creating servers/clients, registering channels, client activated, ...

Little (off-topic) announcement...
Hi all .NET-folks out there! Since I really feel like being a part of this great community, I would like to announce my marriage! Yes, I'm going to get married on the 12th of July with Nele. Ofcourse (as a software engineer I had to) I've made a website with some info about us. I really would appriciate if you guys and girls could sign the guestbook. Since the site is in Dutch, I think most of you don't understand al the topics, but if you are intrested, feel free to take a look. Anyway thanks in advance for your intrest and/or nice words!

Autocompletion in the command prompt!
Roy Osherove posted a link to some cool Registry settings. One of them I found quite usefull: Enable AutoCompletion in Command Prompt. Once this setting is done, you can use the tab key for autocompleting while typing in the command prompt (cmd)! For example you type "cd c:\progr" (without return) and press the tab key, "progr" will be completed to "Program Files".

Eureka! SoapExtension problems solved!
Maybe you've read my post about the problems I had while using a custom SoapExtension class. Thanks to an anonymous reaction, I found the sollution!! I was testing the webservice by using the default test page from Internet Explorer, but the testpage in IE uses the GET protocol, not the SOAP protocol. So there was nothing wrong with my code (I started believing I really sucked ;-), I only had to make a very simple test application. Thanks again to the person who submitted this tip!

Simple Comparer for sorting in VB.NET
I don't know if something like this exists, or even is available in the .NET Framework itself, but I had to make a routine to sort a collection of objects, so I built a simple comparer class. The comparer class can be used like this:
Dim customers As New ArrayList
'Or you can use the Sort method of the strong typed collection,
'inheriting from CollectionBase.
customers.Sort(New SimpleComparer("Name"))
'or
customers.Sort(New SimpleComparer("Name", SortOrder.Descending))
The complete code for SimpleComparer class is:
Public Class SimpleComparer
Implements IComparer
Private _propertyToSort As String
Private _sortOrder As SortOrder
Public Sub New(ByVal propertyToSort As String)
Me.new(propertyToSort, System.Windows.Forms.SortOrder.Ascending)
End Sub
Public Sub New(ByVal propertyToSort As String, ByVal sortOrder As SortOrder)
MyBase.new()
_propertyToSort = propertyToSort
_sortOrder = sortOrder
End Sub
Public Function Compare(ByVal x As Object, ByVal y As Object) As Integer _
Implements System.Collections.IComparer.Compare
Dim prop As Reflection.PropertyInfo = x.GetType.GetProperty(Me.PropertyToSort)
If Me.SortOrder = SortOrder.None OrElse prop.GetValue(x, Nothing) = _
prop.GetValue(y, Nothing) Then
Return 0
Else
If prop.GetValue(x, Nothing) > prop.GetValue(y, Nothing) Then
If Me.SortOrder = System.Windows.Forms.SortOrder.Ascending Then
Return 1
Else
Return -1
End If
Else
If Me.SortOrder = System.Windows.Forms.SortOrder.Ascending Then
Return -1
Else
Return 1
End If
End If
End If
End Function
Public Property SortOrder() As SortOrder
Get
Return _sortOrder
End Get
Set(ByVal Value As SortOrder)
_sortOrder = Value
End Set
End Property
Public Property PropertyToSort() As String
Get
Return _propertyToSort
End Get
Set(ByVal Value As String)
_propertyToSort = Value
End Set
End Property
End Class
