Use LINQ and Visual Basic 2008 to Get a List of Buttons from a Windows Forms Form

Mike McIntyre [MVP Visual Basic] — Sun, 19 Oct 2008 13:50:00 GMT

Example:

' Create a LINQ query.

Dim buttonQuery = From control In Me.Controls Where TypeOf (control) Is Button

' Create a list of object.

Dim buttonList = buttonQuery.ToList

' Iterate through the objects in buttonList.

For Each btn As Button In buttonList

' Show each button's text property.

MessageBox.Show(btn.Text)

Rename Files with the Visual Basic My Namespace Computer Object

Mike McIntyre [MVP Visual Basic] — Sun, 19 Oct 2008 13:38:00 GMT

My makes it easy to use .Net. Here's an example that uses My to rename a file:

Syntax:

Public Shared Sub RenameFile ( _
file As String, _
newName As String _
)
file is the file path to the file to be renamed.

newName is the new name (with file extentsion) to be given to the file.

Example:

My.Computer.FileSystem.RenameFile("C:\OldName.txt", "NewName.txt")

Look Mom, no parameters! Relaxed delegates in Visual Basic 2008 (VB9)

Mike McIntyre [MVP Visual Basic] — Thu, 01 May 2008 18:59:00 GMT

Relaxed delegate conversion, introduced in Visual Basic 2008, enables you to assign subs and functions to delegates or handlers even when the signatures are not identical. Therefore, binding to delegates becomes consistent with the binding already allowed in method invocations.

In Visual Basic prior to 2008:

Sub OnClick(ByVal sender As Object, ByVal e As EventArgs) Handles RunButton.Click
MessageBox.Show("Visual Basic prior to VB 2008")
End Sub

In Visual Basic 2008 (VB9)

Sub OnClick() Handles RunButton.Click
MessageBox.Show("Look Mom, no parameters!")
End Sub

PInvoke Interop Assistant (FREE) - Making PInvoke Easier to Use

Mike McIntyre [MVP Visual Basic] — Sun, 16 Mar 2008 09:29:00 GMT

Jaren Parsons of the Microsoft Visual Basic Team created PInvoke Interop Assistant. In a blog announcing the tool he says: “The motivation behind this tool is writing PInvoke is a hard and often tedious task. There are many rules you must obey and many exceptions that must be taken into account.”

Visual Basic 2008 - Local Type Inference

Mike McIntyre [MVP Visual Basic] — Sat, 12 Jan 2008 09:05:00 GMT

Local type inference is an important new concept to grasp as one approaches Visual Basic 2008. Many new features in VB 2008 are dependent on it. Below is a brief introduction to local type inference followed by a link to a MSDN resource where you can learn more.

Introduction

In Visual Basic 2008 you can get strongly typed local variables without using the 'As' clause to explictly set the variables type. Here is an example of declaring a strongly typed variable in prior versions of Visual Basic for .NET and assigning it an integer literal:

Dim myInteger As Integer = 10

In Visual Basic 2008 you can get the same result - that is a strongly type variable - like this:

Dim myInteger = 10

The Visual Basic 2008 complier will strongly type the myInteger variable by infering the type from the integer literal. It analyzes the value assigned to the local variable myInteger (the integer literal 10), determines it is of type integer, and strongly types myVariable as in integer.

Silverlight

Mike McIntyre [MVP Visual Basic] — Wed, 26 Sep 2007 09:20:00 GMT

Below are some of the links I have found useful for learning about, and developing with, the Microsoft Silverlight technologies.

As a Visual Basic programmer you may want to start learning what Silverlight development is all about. Because Visual Basic in .NET can be used as a static or dynamic language, there are some unique opportunities emerging in Silverlight development for Visual Basic programmers.

Microsoft Silverlight (WikiPedia)
Abstract:	Microsoft Silverlight (code-named Windows Presentation Foundation/Everywhere or WPF/E) is a proprietary runtime for browser-based Rich Internet Applications, providing a subset of the animation, vector graphics, and video playback capabilities of Windows Presentation Foundation.

Microsoft Silverlight (Microsoft)
Abstract:	Microsoft Silverlight is a cross-browser, cross-platform plug-in for delivering the next generation of .NET based media experiences and rich interactive applications for the Web. Silverlight offers a flexible programming model that supports AJAX, VB, C#, Python, and Ruby, and integrates with existing Web applications. Silverlight supports fast, cost-effective delivery of high-quality video to all major browsers running on the Mac OS or Windows.
