I dont have a POS printer so I plan on using an ordinary printer.

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

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?

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)
am developing an application where a client send data to server (socket Programing) and the server recevices it and shows it to the user through a list view but the client can send the data any time they want and it should show on the list view automatically...

server.

Let's say an application needs to persist mostly immutable data. Let's say the application's data files can grow fairly large. How would you implement a simple transaction processing so that changes are either successfully committed or rolled back?
The only requirement is to use built-in .Net libraries. (no databases, no third party libraries)
Here's my current solution. The data file will have three main sections: (1) header, (2) data, (3) index. For now, the header section simply contains an offset to the start of the index section. The data section will store mostly immutable data. The index section will contain serialized objects with enough information to access the data section.
When the application starts, it only needs to deserialize objects from index section. Anything from the data section can be fetched as needed. As the application gets ready to write changes, it makes a temporary copy of the original header and index sections. These would be small relative to the data section. New data would then be appended to the original data section. Once all data has been written, in memory objects would be serialized to the end of the file to become the new index section.
If all this goes without a hitch, the temporary file can be deleted. If something goes wrong, the temporary file can be used to restore the data file to its original state.
Will this work or is there a more elegant approach?
i just write code for application, in which data is get by user and entered data is to print in a particular format?give me a code for vb.net button by which after click on it will print entered data?
View 1 RepliesYpos = TopMargin + Count * PrintFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())
Count = Count + CInt(ROData(x, 4))
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.

I've a Crystal Report of one page. Only one.
I want to clone that page, so when you print that report, you get 2 copies with the same data.

Use software, generate Crystal, go to in-built crystal viewer print button, write '2' in copies, print.
I WANT ->
Use softwre, generate Crystal, print dialog come up (this is done), you hit 'Enter' and 2 copies will be printed (a.k.a 2 pages which are the sames)
I looked up for sub.reports but i don't want them in the same page.

Printing the array in table format is no problem but I'd like to add lines to the printout so that it looks like a real gradebook. I might also like to change the background color of each odd line printed to make the data easier to read.
