I have designed a front end screen for a simple login page with two fields username and password in ASP.net/VB.net. I want the data that I enter into the textboxes to be populated into the database, on click of submit button and a confirmation message like 'Your data has been entered successfully'.Please explain me two things.1.How can I connect to the database and how should the insert statement be?

We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.

It is not my preferred choice, but the user have the database and server working just as he wants it, and do not wish to change, at the same time I do not wish to change programming language. Is that even possible? Can we actually write VB 2005 programs that will run in client computers complete with NET framework 2.0 to access a Linux operating database?

We are writing a program to work alongside our SQL/VB.NET-based POS system.We can both co-exist in the same SQL instance, but we have to keep the two databases separate. Any extra columns that don't belong in their tables causes their DB maintenance to fail, so I have a second database with all of their table names, with column 1 being the GUID from their table, and the remaining columns are the ones that I needed to add, and I'm going insane having to split between the two. I've looked into a lot of different ways to handle my issue below, and the only thing that I can seem to get working are datasets created at runtime through code. I can get SELECTs into my program just fine, but my problems are when I want to run loops on the datasets, and then insert, update, or delete back to SQL.
My first problem is that every time I run the select command to fill the dataset, it duplicates the entries in the dataset. The only way I know how to stop it is to clear the dataset before each poll, but I don't want to erase what's in the dataset. I want to insert the records that don't exist, and update the ones that have changed since the last poll. How can I say "only insert new records into the dataset that are not already in there"?
I have a Windows service set up with a timer that runs a "Check for New Tickets" function stored in the SQL Server every 5 seconds to check for new tickets. It returns 1 if there are New Tickets, or 0 for No New Tickets. When SQL returns 1 to the service, then the service will temporarily stop the timer to process stored procedure 2, which gets all the new ticket GUIDs and inserts them into a dataset to process. The part that I'm having trouble with is using if-then logic to run different procedures based on different variables returned from the database (i.e. what items are on the ticket, who created the ticket, if it's from workstation B, run this procedure, mark the ticket as synced, etc.) So my goal is to get data from the SQL server, run logic to update the dataset, and then update it back to the SQL server, or insert/delete/etc.). I know it's possible because this book I have steps you through it, but the book's examples don't fit what I'm trying to do.
For example, there is a bit column called 'TicketHasCarWash', 1 is yes, and 0 is no. If the ticket has a car wash, I need to determine what kind of car wash they have. There is a table called 'TicketItems' where the car wash type is stored. I need to say "For each ticketGUID in the dataset where "HasCarWash = 1", UPDATE LocalDataSet SET CarWashType = (SELECT CarWashType FROM SQL.dbo.TicketItems WHERE TicketGUID = @TheTicketGUIDOfTheCurrentRowInTheDataset) Next.
After inserting into masterTable it returns an ID. With that ID I want to enter more than one row into a transaction table.

My Problem is that I want to give user a message if the delegate limit has reached for that course.See I have a course where I have MinDelegate and MaxDelegate limit.

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.
View 4 RepliesI am INSERTING into 2 different tables with 2 different buttons (One after the other by clicking each button). I have a form with 1 button directly on it to INSERT into tblCustomers from a field that is directly on the form as well. I then have a TabControl with another button with other fields (5 to be exact).
After I add data to the data base by filling out the field on the form and then by first clicking the add button located directly on the form and then add data to the fields directly on the TabControl the data will not INSERT itself into the tables in the data base for the 2nd table. Only the first table get data in it and not the one related to the TabControl.
BUT if i add data in the TabControl and then click the button on the TabControl it adds data into to the 2nd table. Is there a way to refresh my program so that it will accept both the "forms data" and the "TabControl data"?
I have problem when i inserted data. the error show String or binary data would be truncated. What is meaning of that??

I am pulling data from one SQL Server database, formating the data and then inserting it into another SQL Server Database. I am looking for a faster way to do this than the one I am currently using. The data pull is about 37,000 rows, so formating it and inserting it one row at a time is very time consuming. I was hoping I could format it into a datatable and insert the datatable into second database essentially inserting all rows at the same time as if they wre within the same databse, but I have not found a way to do this.
Essentially the code (I have simplified it) that I am using...
