Delegates in .NET: A Primer on Creating Type-Safe References to Methods in Visual Basic .NET

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

Delegates, new in Visual Basic .NET, are type-safe, object-oriented references to methods. By using delegates, you make your methods accessible to others and therefore more extensible. This article provides an introduction to delegates, their benefits, and how they are used.Here the author shows you how to declare, create, and use delegates to invoke instance and shared methods at run time, and how to implement delegates as properties. He then goes on to provide examples of how delegates are used for callback functionality and explains the relationship between delegates and events. Finally, the article provides a glimpse at how delegates are implemented in intermediate language code by the Visual Basic .NET compiler.

GDI+: A Primer on Building a Color Picker User Control with GDI+ in Visual Basic .NET or C#


Although most developers and APIs use the RGB scheme when working with colors, it's not the only available way to represent or select colors. For instance, the standard Windows color-selection dialog box allows you to work with the HSL color scheme in an indirect way. In this article, the author describes several color selection schemes, and uses GDI+ (via the System.Drawing namespace) to create a component that makes it possible for your own applications to provide a simpler, friendlier color chooser. Along the way, you'll get tips to help you use GDI+ in your own apps.

Why do we say delegates are type safe as compared pointers???


Two questions:

  •  Why do we say delegates are type safe as compared pointers ?
  • Can we define a pointer in C# ?

Creating a drop down menu with a variable range of cells in excel using Visual Basic


I can create a drop down menu using a range of cells as follows:

    With Selection.Validation
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
        xlBetween, Formula1:="=$G$2:$G$10"
        .IgnoreBlank = True
        .InCellDropdown = True
        .InputTitle = ""
        .ErrorTitle = ""
        .InputMessage = ""
        .ErrorMessage = ""
        .ShowInput = True
        .ShowError = True
    End With

I would like to create the drop down with a range of cells using variables.  For instance, in the line which contains $G$2:$G$10, I would like to substitute something like range(cells(1,2),cells(x,2)) to allow me to change the length of the menu depending on how much data has been entered.  Does anyone know how I can do this?
