This sounds like a homework assignment.
Try something like this ...
Create a message table with timestamp, usernameTo, UserNameFrom, Status (Read/Unread), MessageText.
When someone sends a message, you insert a record into this table.
You would have to create a client application which checks to see if a message is pending for your current user and retrieve it from the db and display it in a chat window.
The other guys who replied are correct, you need to investigate TCP/IP chatting otherwise your client application will be constantly polling the db for new messages. However, i think this basic design will get you through your homework assignment.

Dim Ssql
Dim dbstatus
Dim rs
'*************
Ssql = " Select * from User_Access A Where A.User_pwd ='1234' "
set rs = Server.CreateObject("ADODB.RecordSet")
rs = DB.execute(Ssql,dbstatus)
Response.Write(dbstatus)
If dbstatus <> 0 Then
'Error code here
Else
'code here
END IF
'*************
The code is working ok . On successful execution of sql statement the dbstatus value is giving -1 . But according to the code it should return 0 for further execution . For other than 0 it will give Error .
I'm executing this on sql server 2005 and in windows 7.
***But the same code On successful execution of sql statement the dbstatus value is giving 0 on some other enviornment where ODBC version and sql server version is different .
Can anyone help me out .
Thanks in advance

You can either change the specs (requirements to run your software), or the software (have it check the version of the available drivers/software and act accordingly). We mostly choose the first option.
Write down the versions of the ODBC-driver, and update the out-of-date systems to match your test-server.

Production Environment version :-
OS windows server 2003
sql server 2000
ODBC 3.526.3959.0
My Testing Environment version :-
OS Windows 7
sql server 2005
ODBC 6.1.7600.16385
What shall i change from above to execute the code . Software i can't change i have no authority to do that.Please help me out

And which of those two returns the correct results?
That's the one with the correct ODBC-version. I suggest you stick to that particular version, and not start supporting "random combinations of versions".

Write down the version of the ODBC-driver, and make sure the other machine uses the same version.
The reason we "have" versions is because things tend to change. That means that those two ODBC-versions that you are working with work different, with different assumptions. The older one might have bugs that are solved in the new version. The framework might expect the old bug, and not be able to cope with the new version. There's all kinds of stuff that can go wrong, and unless you know WHAT has been changed in the ODBC-driver, you simply use the LATEST version that you tested against.

Hi
I am new to VB .Net and is currently using VB2008. I have created a MDI Parent form and and MDI Child Form
On clicking a Menu item in MDI Parent I am trying to Enable/Disable a Text Box in Child. But this is not working. Can somebody tell me how to do this?
In the Menu Iem Click Event I am putting the code as Parent.child.txtbox.enabled = True. But when I run the program the text box is not getting enabled. 
Note: The child form is loaded along with the Parent form. It is not called from any menu Item.

I highly suggest picking up a beginners book on VB.NET and working through it.
Right now, you're just guessing at what may work and that's not a good idea when dealing with the basics of a language and framework.
Your should be declaring an Interface that your MdiChild form implements, exposing a method that the MdiParent form will use to tell the child to enable/disable the textbox.
Public Interface ISampleInterface
Sub EnableTextBox(enable As Boolean)
End Interface
Public Class MyMdiChildForm
Implements ISampleInterface
...
Public Sub EnableTextBox(enable As Boolean) Implements ISampleInterface.EnableTextBox
MyTextBox.Enabled = enable
End Sub
End Class
MdiParent code:
Dim newChild As New MyMdiChildForm
newChild.Parent = Me
newChild.Show
.
.
.
newChild.EnableTextBox = True
If you can't understand this code or have questions on it, you REALLY need to go through a beginner book.

Thanks a lot Dave. I will go through the Beginner's book. But I do have invented a crude method to take care of the same for the time being.

Don't get into the habit of doing things the wrong way. You're just going to paint yourself into a corner later.

Hi Dave
Thanks for the advice.
I doubt this will happen since what I am doing is closing the earlier opened form and re-opening the child again. A few micro-seconds extra, maybe, but hardly noticeable I am sure. This does the work very simply.
In case you can think of any problems which it may raise in future I will surely like to know. 
Thanks again
Sandipan

I wasn't talking about your current application. I was talking about the bad habits you develop that are hard to break and prevent you from solving problems correctly in the future.

I'm developing a VB Window's Forms application in Visual Studio 2010. I choose an object out of the forms toolbox, say a chart. Then I adjust the properties in the properties window to get what I want. Is there any way I can see the actual code that generates those properties?

You could open the containing folder for your project and then find the <formname>.Designer.vb file and open that file as a text file. I do not think that it shows up in your solution explorer by default.

Visual Studio offers a "show all" button in the solution pane.

recently I converted a database migration utility from VB(VS6 sp6) to VB.NET(VS 2008 SP1). It is ported succesfully. I am able to open it development M/C. But if I am trying to open the same application in installer M/C.(Fresh machine) my application is crashing.
can anyone let me know what run time dll should be included so that it will work fine.
System Details
1: XP SP3

The .NET Framework should be included; the same version that you used to develop against. You can't install just "a few dll's", as most of them have quite some dependencies.
Does your installer have an option to see if there's a .NET framework?

1) Open VS 2008 and load the project.
2) Right click the project name in solution explorer and select properties.
3) Select the Compile tab and click the Advanced Compiler Settings
4) Check the target Framework version
5) Install that Framework version on target machine
6) Build project and copy EXE file to target machine

vb6 sp6 working in virtual XP machine under win 7
This setup has been working fine and the projects have existed for years but a couple of them have started failing to compile
They all compile and run ok with Control F5 (Run with full compile) but when you use the File->Make xxxxx.exe option it works for a while and the progress line of "Writing EXE" partially colours blue and it then stops with
Microsoft Visual Basic, "Unexpected Error" Ok Help
Help tells me I may have a hardware or software error. gee you think
At least one of the failing projects hasn't been modified (using sourcesafe so I can be sure of this) since it last compiled ok
Other projects compile ok
Does anyone have any ideas where to look for more info?
EDIT: Things I have checked
There is plenty of free disk
running the compiler from the command line gives the same result
a repair install doesn't change anything
repeat install of sp6 didn't help

In 2008, as that's when extended support for VB6 ended 
FWIW;
- Make sure you registered all the controls that you're using
- Compile under Windows XP, or download XP-mode for Windows 7
- Keep removing code (comment it out) until you got something that compiles again
- Start migrating to VB.NET; the compiler is free, and you can mix VB6 and .NET code, using the Interop ToolBox from Microsoft.
- Check if the VB6 IDE created a logfile under C:\Windows\System32, and check the EventLog for clues.
