Make An Online Transaction Program?
May 6, 2009
I want to make an online transaction program for which I need help. The problem is that, if a branch enters an entry that entry should hit three system�s databases. These three systems are connected to network but the application is not connected. For example, there is two branches namely branch1 and branch2 and a head office namely HO1. If a user at branch1 enters a record that record not only hit that branch database, but also hit branch2 and HO1 databases as well. Can I use Virtual Private Network (VPN) to do this?

I get this error at the Commit of a transaction in a desktop application:
This OleDbTransaction has completed; it is no longer usable.
Other posts I have seen with similar error suggests this can occur if it takes a long time, or contains large amounts of data. This is not the case here.Logging tells me it takes 140 ms from Begin to Commit and about 10 commands executed inside the transaction.It is using an Oracle database.This class is a simplified version of my database class:
Class MyDatabase
Private mConnection AS OleDbConnection
Private mTransaction AS OleDbTransaction
[code]....
Is it not allowed to run a select inside a transaction like this? Or can it be done by running the transaction in a specific isolation level (I see that the BeginTransaction method has an optional parameter for doing this) ? ..Or some other sollution..? In my case, it was not a problem to move the select to run before the transaction started, but what if you need to run selects that must run inside the transaction?

I've seen plenty of examples of transactions in the actual store procedure's SQL. But I'm wanting to do the transaction and keep track of it in code. I tried this but it says that my insertcommand's transaction object is null. How can I fix this?
vb Dim conn As SqlConnection = DBConnections.SQLServerConnection
conn.Open()
Dim params(1) As SqlParameter
[CODE]....

What is this kind of exception?
Error : Execute requires the command to have a transaction object when the connection assigned to the command is in a pending local transaction. The transaction property of the command has not been initialized..
This one causes the error: Dim oOperation As COperationOutputTypeBS
oOperation = COperationOutputTypeBS.GetOperationOutputType(txtOperationCode.Text)

I have a customer that does not allow for local installation of any version of MSDN so telling me to press the help or F1 key in VB6 will not help. What I need is a link to VB6 IDE functionality (ie all of the special characters in the find dialogue to help in searching or how to effectively use "use pattern matching" when I press CTRL+F).

I was looking at this example: Basic TCP Communication I was really amazed by this piece of code however it only works in WLAN. I was thinking if its possible to make the same program over internet not the same router but which can be connected to two different countries or any other place except the same network?
Actually I have created a very simple game called whack a mole. In which buttons appear and the user has to click it before it disappears. however I am trying to make it multiplayer over the internet even if i have to create a server from my PC. I dont know if its even possible. The other player should also get the same screen as the user who hosted the game just like real time.

I have finished developing a small, completely useless but working project. It was my first in VB.
What i wouold like to know is how is the best way to get this project online for download?
I dont have a web site or web page, and this project is just a bit of fun (fitness test).
Could anyone tell me the steps I have to take? All i want from it, is to be able to place a series of screen shots explaining the project and then if someone should wish to download it they can.
I dont need prime time internet coverage, just a place to put it online, pref free. Plus, there have been many kind people from this forum who have given me thier free time and effort to help me with code issues, so if I am allowed and any one is curious i will post the site link to here and you can see where your effort has gone to, and should you wish provide positive and negative comments at your leasure.

I started working on a big project for like 5 mins ago. Then suddenly I figgerd out that I don't know (AT ALL) how to make a program that can:
- Connect up to a server (which will be my secound computer)
- Chat
- Make groups
- Etc
the login system is simple but the client server thing is another story.So basicly what im asking about is: How can I make a program that connects to a server (this should not be local).

If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
