Update: I changed the title and some other things because they might have mislead thinking that this article gives you the in’s and out of USB programming.
The purpose of this post is simply to let you know of some codes/librairies available to help with usb programming like detecting when a usb device has been added/removed, which the .net based class helps with, ect…
__________________________
Visual Basic 6.0; VB 5.0
The first library is for Visual Basic 5 and 6.0 and is provided by Intel (Intel is the main inventer of USB as well) and includes various bas/modules for use in your applications. I’ve had this link and files on my vbcodesource.com page for years but now that I found a .net library that can do alittle something with usb devices I figured it would be worth making a post for both of them. BTW, these VB 6.0 USB modules do Much more than the below .net library.
Click here for the Main Intel page with the downloads and tutorial…
Visual Basic.NET Compatible Class Library
Strolling through some of the latest updates at thecodeproject.com I noticed someone made a USB library using C# for detecing the attachment and detachment of usb devices. He provides the source code, compiled class, and a demo app with the usb library in action. If you simply want the class to make a reference to, then download the source code version. Then under the Bin/Release directory you will see the ‘USBClassLibrary.Dll’ which is what you want to make a reference to.

Although I don’t provide any examples or anything, hopefully this will at least give you a nice jump start on getting your USB basics taken care of. Have Fun!

Overview
The Microsoft .NET Framework 4 provides the following new features and improvements:
- The .NET Framework 4 works side by side with the Framework version 3.5 SP1. Applications that are based on earlier versions of the Framework will continue to run on that version. Just a subset of functionality is shared by all versions of the Framework.
- Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.
- The ADO.NET Entity Framework, which simplifies how developers program against relational databases by raising the level of abstraction, has many new features. These includes persistence ignorance and POCO support, lazy loading, test-driven development support, functions in model, and new LINQ operators.
- Enhancements to ASP.NET:
- New JavaScript UI Templates and databinding capabilities for AJAX.
- New ASP.NET chart control.
- Improvements in WPF:
- Added support in Windows Presentation Foundation (WPF) for Windows 7 multi-touch, ribbon controls, and taskbar extensibility features.
- Added support in WPF for Surface 2.0 SDK.
- New line-of-business controls including charting control, smart edit, data grid, and others that improve the experience for developers who build data centric applications.
- Improvements in performance and scalability.
- Visual improvements in text clarity, layout pixel snapping, localization, and interoperability.
- Improvements to Windows Workflow (WF) that let developers to better host and interact with workflows. These include an improved activity programming model, an improved designer experience, a new flowchart modeling style, an expanded activity palette, workflow-rules integration, and new message correlation features. The .NET Framework also offers significant performance gains for WF-based workflows.
- Improvements to Windows Communication Foundation (WCF) such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support, durable two-way communication and rich hosting capabilities. Additionally, .NET Framework 4 provides new WCF features such as service discovery, router service, simplified configuration and a number of improvements to queuing, REST support, diagnostics, and performance.
- Innovative new parallel programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordination data structures which let developers harness the power of multi-core processors.

Textbox Manipulation in VB and .NET – Using API
By admin | July 21, 2008
(5 votes, average: 4.6 out of 5) Loading ...
This is a basic article on how to do various textbox manipulating that isn't exposed in your normal VB or VB.NET textbox like Page Left or Scroll to the Edge (That I am aware of anyways).
Note: These codes are basically taken from a example I made at my vbcodesource.com site for VB.NET that shows how to do lots and lots of various textbox based manipulating. Just go to http://www.vbcodesource.com/ under the Visual Basic.NET - Examples page.
So in Part #1 of this article I will present some codes that will accomplish what is outlined below to a textbox control...
Page Left
Page Right
Line Left
Line Right
Left Edge
Right Edge
_________________________________
To accomplish these features I will use the tried and true Windows API. Specifically the SendMessage Function is used. Below is the declaration for VB Classic and VB.NET
Visual Basic 6.0
'Used to Send Messages to the control.
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal winHandle As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Visual Basic.NET 2002/2003/2005/2008
'
Used to Send Messages to the control.
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal winHandle As Int32, ByVal wMsg As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Int32
_________________________________
Now for some Constants...
Private Const WM_HSCROLL = &H114
Private Const WM_VSCROLL = &H115
Private Const SB_LINERIGHT = 1
Private Const SB_LINELEFT = 0
Private Const SB_PAGERIGHT = 3
Private Const SB_PAGELEFT = 2
Private Const SB_RIGHT = 7
Private Const SB_LEFT = 6
_________________________________
Now all thats really needed is the textbox you want to send messages to and calling the sendmessage api with the right combination of contants to perform the intended function.
_________________________________
NOTE: If your using VB 5.0 or VB 6.0 then change some small things below...
Change - txtControl.Handle.ToInt32 to txtControl.hWnd
Change - Unless your getting the SendMessage functions return value then remove the parentheses which are the ( and ) characters.
Thats basically the only changes that are needed.
_________________________________
Page Left / Page Right
'
'Move the position pageleft.
SendMessage(txtControl.Handle.ToInt32, WM_HSCROLL, SB_PAGELEFT, 0)
'
'Move the position pageright.
SendMessage(txtControl.Handle.ToInt32, WM_HSCROLL, SB_PAGERIGHT, 0)
Line Left / Line Right
'
'Move the position left.
SendMessage(txtControl.Handle.ToInt32, WM_HSCROLL, SB_LINELEFT, 0)
'
'Move the position right.
SendMessage(txtControl.Handle.ToInt32, WM_HSCROLL, SB_LINERIGHT, 0)
Left Edge / Right Edge
'
'Move the position to the left edge.
SendMessage(txtControl.Handle.ToInt32, WM_HSCROLL, SB_LEFT, 0)
'
'Move the position to the right edge.
SendMessage(txtControl.Handle.ToInt32, WM_HSCROLL, SB_RIGHT, 0)
_________________________________
Thats basically all for Part #1. These 6 features do not have native VB or VB.NET codes and therefore the API's are used. As you can see though its pretty simple to add..
Part #2 will go over: Page Up/Page Down, Line Up/Line Down, and Top Edge/Bottom Edge.
Till then, Have fun!
