":=" Syntax Within Parameter Lists

[eBob.com]

I've been searching for a good example of gradient graphics. I didn't find
much, but I did find the one below which I like because it looks really
simple. EXCEPT for the ":=" syntax in the parameter lists! I've never seen
that. It's impossible to do a Google search on something like that and find
anything useful. I've checked my several VB.NET books and their indices
have nothing on this syntax. The web page I found this on claimed that it
was a VB.NET example. I hope one of you can enlighten me.

Thanks, Bob

Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click

'local scope
Dim myGraphics As Graphics
Dim myBrush As System.Drawing.Drawing2D.LinearGradientBrush
Dim myRectangle As Rectangle

'return the current form as a drawing surface
myGraphics = Graphics.FromHwnd(hwnd:=ActiveForm().Handle)

'create a rectangle object
myRectangle = New Rectangle(x:=5, y:=5, Width:=40, Height:=50)

'draw the rectangle to the surface
myGraphics.DrawRectangle(pen:=New Pen(Color.Black), rect:=myRectangle)

'create the gradient brush
myBrush = New System.Drawing.Drawing2D.LinearGradientBrush( _
rect:=myRectangle, _
color1:=Color.White, _
color2:=Color.DarkSlateBlue, _
LinearGradientMode:= _
System.Drawing.Drawing2D.LinearGradientMode.Vertical)

'fill the rectangle using the gradient brush
myGraphics.FillRectangle(brush:=myBrush, rect:=myRectangle)

End Sub

Using named parameters is mainly useful if you are dealing with optional
parameters and only want to provide custom parameter values for some of
the parameters.
