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

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)

First, a little background (greatly simplified): I have two classes, one called Entity and one called Item which a subclass of Entity. They each store their individual properties in seperate SQL 2008 tables using TableAdapters generated by a strongly typed DataSet. The Entity class has a Save() method that looks like this:
Public Sub Save()
entityTableAdapter.Update(entityRow)
End Sub
[Code]....
Indeed, the SQL table does not contain a row in the Entity table with the necessary ID at this point because the transaction is not complete.
My goal is to prevent the Entity record from being inserted if inserting the Item record fails. I could write code to delete the Entity record again, but this does not seem very elegant to me...

Opens a serial connection when a radiobutton is selected. My question is: How can I make a message pop up saying "COM Port in use" if the radio button is selected when the com port is in use by another application? Right now, the program just crashes.

I have 2 tables in MySQL database. These table were joined through a query and handled by a dataset. Im displaying these data through setting the dataset as the datasource of my datagridview. But when it comes to Update, Insert and Delete statements, I got an error because the sqlcommandbuilder does not generate statements in multiple tables.I want is, when I press the update button..all the changes made in the datagridview will be updated in the database. Can i make it without creating a datasource in design mode or through smart tag? If I have to manually create an UpdateCommand for adapters..Can I have a code snippet for that?

I created a project using Visual Studio 2008 Express and I use the Menu tool called Build. There are two selection for the express (Build and Publish).I used the Build and found an .exe in the "bin" folder and the "Debug" subfolder. I am able to double click this .exe file and the program executes.
If I move this .exe file to 2 levels up on the directory, the .exe starts with my (modal form) and then it hangs. how I can make an .exe file that would execute in a different level?

You see three buttons which all contains a one digit number (1, 2 and 3) at the start of running a program. There is one other button stating "Randomize" and when you hit this randomize button all the three buttons that were first containing 1, 2 and 3 are now shuffled in a random order like 2, 3 and 1. In fact, when clicking the randomise button the figures will stay between 1 and 3.I was hoping to sort this out with the following code but it didn't actually work at all:
Dim a, b, c, d, x As Integer
a = Button1.Text
b = Button2.Text

Create a GeneratedNumber application that stores in an array with indexes 1 through 100 numbers generated by the index values when Generate is clicked. Generate the number to be stored at each index by summing the index and it's individual digits. For example, 25 should be stored at index 17 because 17+ 1+ 7 = 17 and 4 should be stored at index 2 because 2+ 0 + 2.
Your program should use a FillArray() procedure to generate the nuymbers and DisplayArray() procedure that displays each index and its element in the list box.

I have a file called CalcProg.DLL written in Delphi which is used in Plaxis. I am planning to write a VB.net wrapper for this DLL. The problem is that I don't know what function names there are in the DLL. I was wondering if there was a wrapper generator so I could input a DLL and the generator generates a dummy CalcProg.vb with the function names so I could have a VB class that does something like this:
