whow do you develop validations in programming using visual basic?

This question is pretty vague. If you're serious about getting a good answer you have to make it more specific. VB6 or VB.Net? Web Forms or Win Forms?\n\nIf it's VB6 then you simply write the code to do what you need it to do. You want to validate user input immediately after the form has been submitted for processing. \n\nIf it's VB.Net then you can use the Validator controls. The method is different based on whether it's a web from or a windows form. \n\nHere are some .Net tutorials:\n\nhttp://samples.gotdotnet.com/quickstart/aspplus/doc/webvalidation.aspx\n\nhttp://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbconValidationOfControlDataOnWindowsForms.asp\n\n\n\ngood luck

You can download a free version of Visual Basic from the link below.  Once you register, you'll get access to a free e-book, "Build a Program Now!", which I think is very good.  This version of Visual Basic includes .NET 2.0.\n\nThe other two links are Microsoft's information on Visual Basic and .NET.

1. NO KNOWLEDGE OF VISUAL BASIC. (Go with C/C++. Hell, even java or perl works.)\n\n2. The bare minimum: SMTP, POP, IMAP, SSL, the language you're programming in, MIME, e-mail server structure, basic network calls. I reccommend reading some of the RFCs here: http://www.lemis.com/email/email-rfc.html

Some form of BASIC - the BEGINNER'S All-purpose Symbolic Instructions Code. Visual BASIC.net is the most recent version, and can be used to make web-enabled programs. The site I've listed below is run by a college professor who writes textbooks - it's an e-mail list.

I learnt VB 6 years ago by reading Visual Basic 6 for Dummies\nby Wallace Wang. The book is very good for beginners.\n\nHere is another good site: http://www.profsr.com/vb/vbless04.htm

Install Visual Basic 6.0 on your computer and use Visual Studio's one of the wizards to create your first application. Use help. Make changes. Observe change in behavior... Try try try.

goto this site for VB.Net and C# :\nhttp://www.samspublishing.com/articles/article.asp?p=31560&seqNum=1&rl=1\n\ntry to find for ASP in internet, i'm too sleepy right now.\n\nbtw, why didn't you open the sample source code from VB and ASP, there's must be a sample source code with 2 or more form.

This code is the minimal. Here it validates the user name and password are admin. In case both the values are admin it allows login. Else it returns an error message - error!\n\nThe only thing that may be confusing for you over here may be the session concept. \n\nThis code has no databse connectivity. Incase you are planning for a database based project use a MS Access connectivity. Its easy.\n\nLet me explain this code\n\n<% IF Request.form="" THEN %> \n<html> <body> In order to access this pages fill the form below:<BR> \n'THIS IS TO POST DATA FROM THE PAGE\n<form method="post" action="index.asp"> \nUsername: <input type="text" name="username" size="20"><BR> \nPassword: <input type="password" name="password" size="15"><BR> \n<input type="Submit" value="Submit"> \n</form> </body> </html> \n<% ELSE %> \n'IF USERNAME AND PASSWORD NOT admin RETURN an ERROR\n<% IF Request.form("username")="admi... AND Request.form("password")="admi... THEN %> \n<% Session("permission")="YES" \nSession("username")="admin" \n%> \n<html> <body> \n'THEN YOU CAN VIEW PAGE1 &  PAGE2\nHi <% =Session("username") %>, you can view: <BR> \n<A HREF="page1.asp">Page 1</A><BR> \n<A HREF="page2.asp">Page 2</A> \n</body> </html> \n<% ELSE %> Error! <% END IF %><% END IF %>\n\nYou can mail me to technoblitzs@yahoo.com incase you have any clarification or want to connect to  a database.

I agree that Visual Basic 2005 Step By Step, by Microsoft Press, is a good book. It focuses on teaching you how to perform specific tasks with Visual Basic .NET.\n\nIf you are more interested in learning how the language operates, I would suggest Beginning Visual Basic 2005 by Wrox Press.

For client/server work I use vb.net. For web work I use ColdFusion. They are both easy to learn and easy to use.

Microsoft has a LOT of information online that will help you.  See the link below for a good place to start.\n\nThe help files also have code examples.  Just remember that Access and VBA (Visual Basic for Applications) have separate help files -- you have to be in VBA (e.g., via View -> Code) to see the help files for VBA.\n\nFinally, you can always ask questions right here!

Visual Basic is a programming language and software development environment created by Microsoft in the 1990s primarily to make it easy for developers to create client applications on Windows. It featured an way to easily create graphical user interfaces by drawing windows and controls on the screen, and an event-driven paradigm that made it easy to attach code to meaningful events in the lifetime of an application (such as a button click).\n\nThe language was adapted to the Web with a variant called VBScript, and embedded into Microsoft Office and other applications with another variant called Visual Basic for Applications (VBA). Around the time of Windows 98's release, it became possible to create scripts written in VBScript to run on the Windows desktop.\n\nIn 2000 Microsoft introduced a new unified framework for software development called .NET. At that time Visual Basic was thoroughly revised and renamed to Visual Basic .NET. This version of the language added some capabilities, but dropped others, and was incompatible with previous versions of the language, leading some to complain that it should be been released as a separate language with a different name. Still, a great deal of Visual Basic code is in use today and large numbers of developers still use it to create client applications, Web apps, script, and macros embedded in other applications such as Microsoft Excel.

Here's a pretty good one I wrote:\n\nhttp://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=58476&lngWId=1\n\nYou'll need Visual Basic to compile it or you can e-mail me and I'll send it to you...
