This code will explain how to validate an email address and then accept it for processing/using. If you find this code useful, please vote for me.

It took Netscape months to create their first browser, and Microsoft wasnt able to follow up that trick until years later. But you can create a world wide web browser in less than 15 minutes, even if you are a Visual Basic novice! The following tutorial will show you how to create an Internet browser using the Microsoft Internet Control (part of Internet Explorer). My only caveat is that if you end up putting the big-boys out of the Internet business with your creation, that you give me a litle credit in your About box! ;)

This is an implementation of the infamous 'Game of Life'. Made with VC6, as Win32 application. Demonstrates double-buffering, window clipping regions, bitmap buttons and more.

This tutorial shows how you can list the users authenticated in your site using session object.

Drag and Drop in Visual Basic.Net. I haven't found any articles about this essential subject in planet source code or any of my favorite web sites. So I thought I'd help out a bit. Visual Basic.Net has changed the way data is moved using drag and drop techniques. This is a quick redirection to dragging and dropping in VB.Net. It also includes a bit of error handling using "TRY-CATCH" block statements.

Button control array with event handling. This code will show you how to create control arrays in Visual Basic.Net and have each array member respond to events by using the AddressOf operator. Though it looks like a calculator, it has no calculation functions. The purpose of this project is not to show how to create a calculator.

Open and close the CD rom door from code! Note:comment out the unneeded api declaration (16 or 32 bit) depending on what operating system you are using!

Shows a simple way of how to use the Notify Icon control. Includes a simple timer that changes the icon every second so that it appears to be flashing. Simple code for simple project unlike some of the hairy code I found on PSC for doing the same thing in Dot Net. Also shows how to use the contextmenu along with the Notify Icon control. Please vote.

::UPDATED:: With these procedures, you can make your Delphi forms translucent [see through] using some API that's in Win2k and Windows XP. If you like it, please vote. This is written in the newest Delphi version (6).

This code allows for the easy drawing of angle measures (in either Radian or Degrees). It also provides a simple code for drawing lines in VB.NET

This is a working message forum you can use on your web site. It now has user register and logging in features as well as replying to a post. You can try a demo at http://www.vegaware.com/board/forum.aspx

How to print a Microsoft Access report from within VB. Also, VB 16-bit. (by Jose Garrick)

Hello, this is Alexander. Since I finally got an email from someone who liked my previous lesson, I am going to make the second installment. This one will be about variables, and stuff like 'if' statements.

This is the third installment of the Lessons in C programming tutorials created by me, Alexander. In this lesson I will cover loops. Loops basically do what it sounds like, loop. If you have read lesson 2 you should understand some Boolean expressions. If you do not, you should read it again. When working with loops it is important to understand truth and false. Maybe you should try doing some truth tables with problems.

If you've ever wondered how sound applications can show the kilohertz and samples per second information about a waveform file (.WAV), the answer lies in the RIFF file format. The RIFF file format is designed to be as generic as possible. It is used for waveform, AVI, palette, and other information standards that may need to be mixed and used together. Generally speaking, though, any file with a WAV extension will only contain waveform data. RIFF provides information in chunks and subchunks. The header for each chunk describes the length of the chunk and the type of data the chunk contains (WAVE, for instance, is the string identifying a WAVE chunk). The Wave subchunk is immediately followed by the WAVE Format Chunk. It is this small chunk that defines the structure of the waveform data that will follow. It defines the format of the waveform, the number of channels used (with 0 being mono, 1 being stereo), the sampling rate, the kilohertz at which is was recorded, and the data block size. Of these, only mono/stereo and the sampling rate are likely to be of interest unless you intend to write your own custom waveform player.

Updated on May 06, 2005 This was made with Delphi 6.02 Professional And will work with Delphi 5 not sure about any version below. Give it a try with Versions below 5 and email me please. For Beginners to Intermediate This is an intense tutorial on how to create a text editor. Thought that I add something to this sight, instead of just always taken from it. This tutorial is very detailed on what needs to be done, and all source codes are highlighted. With a grayed background. I am very proud of this tutorial and would really like to hear from you, about how you feel about it, and would like for you to votes for us on it. Rather good or bad. Thank you and please enjoy For the images that are used in the editor. that go with the tutorial please click on the email link below. Add Editor Images to the Subject Heading. And someone here at the office will try and find them for you, as this project is very old. And we are not sure if the actual code for it was destroyed or not. But please feel free to contact us anyway, if just to say hello :-) Thanks All; Wayne & Carr Barron Carrz-Fox-Fire Promotions (Please check out our other code samples and Delphi Registry Backup information as well)

The Switchboard:A method for handling subclassing in ActiveX controls f you develop ActiveX controls and intend to subclass or hook a window, you'll very quickly discover a problem when you attempt to site multiple instances of your control. The subclassing, which worked fine with a single instance of your control, now no longer works and is, in fact, most likely is causing a GPF. Why is this happening? The AddressOf operator requires you to place the callback routine in a module. This module is shared between all instances of your control and the variables and subroutines that the module provide are not unique to each instance. The easiest way to visualize the problem is to imagine a shared phoneline (or a partyline as we hicks call it) where multiple parties are trying to dial a number, talk, and hangup, all at the same time. What's needed is an operator, a routine that controls the dialing (hooking), the talking (the callback routine), and who routes information to the instance of the control that requested it. The Switchboard subroutine (see below) and it's supporting code provides a method for subclassing from multiple instances of your ActiveX control. It is not memory intensive, nor is it slow. It's biggest weakness is that it is hardcoded to intercept particular messages (in this case, WM_SIZE, to trap resize events) and will require some minor modification on your part to use.

At some point, you may find it useful to manipulate the location of the mouse cursor. Perhaps you are designing an interactive tutorial, a walkthrough, or maybe you plan on controlling another application through mouse events. Regardless, you will quickly find a number of hurdles to overcome and it is the goal of this example to help you over, under, or around these hurdle

This is a guide meant to help beginner's grasp the basic concepts in Delphi through the simple game of Pong. It includes manipulation of controls and uses the KeyDown Event to control the Paddles.
