JCQ - SignIn & Chatting works fine

I'm pleased to tell you, that I got it to sign on and chat with other clients. Avalon is great at displaying rich text and so implementing colors and smileys is very easy compared to my previous RichTextBox version.
Avalon databinding is so amazing. You can define Converters for every type to make viewable items out of your dump data. I had some problems to attach such a Converter to a dynamically created ListBoxItem but I worked around by using the event when the item is created and added the Convert to the binding by code.

I'll provide screenshots as soon as I get hello working on here ...

Custom Chrome in WPF

Image
Some of you may have wondered who the creators of Microsoft Max did the Chrome. Although this breaks one of the Top 10 Vista rules I will show how to create a WPF window with custom chrome. You can't get there by simply setting the border of a WPF Window to None because always a thick border remains. You have to do a work around and create an empty Win32 window and fill it with your own WPF controls. You can use the HwndSource object to do this. This object is intended to place WPF controls into Win32 Applications but you can also use it to place a WPF control onto your Windows Desktop which is also a Win32 application. HwndSource will call the native function CreateWindowEx and create the window for you. Dim params As HwndSourceParameters = New HwndSourceParameters("CustomChrome 1", 400, 300) Dim hwnd As HwndSource = New HwndSource(params) hwnd.RootVisual = New Page1 This code will create a default window for you. The HwndSourceParameters 's constructor sets the

Capture WebCam with WinForms2

I was asked whether it is possible to capture a webcam's output in Windows Forms 2.0 so I did a bit researching. First I thought I would have to do this in DirectX but then I found some API calls for VB6 and translated them to VB .NET 2. In fact it is very easy to capture the output. You simply need a Control and it's handle. I chose a PictureBox named PictureBox1 to do so. You have to define the Win32 API calls first. We will need two API functions SendMessage and capCreateCaptureWindow . Private Declare Auto Function SendMessage Lib "user32" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer Const EM_LINEFROMCHAR As Integer = &HC9 Const EM_LINEINDEX As Integer = &HBB Private Declare Auto Function capCreateCaptureWindow Lib "avicap32.dll" (ByVal lpszWindowName As String, ByVal dwStyle As Integer, ByVal x As Integer, ByVal y As Integer, ByVal nWidth As Integer, ByVal nHeight As Inte

WPF: Binding updates

Whenever you offer a Cancel Changes command you need to delay updates to the Source until the user Accepts Changes e.g. by clicking OK or Save. Although WPF's two way bindings update the source immediately you can delay the update by adding UpdateSourceTrigger=Explicit to your binding expression. {Binding Path=Text, UpdateSourceTrigger=Explicit} The Source won't be updated until you call BindingExpression.UpdateSource .
