I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

In my datagridview I was fill in using join tables (table1 = pr_employees, table2 = pr_employee_deduction). My problem now is during save button I want to update records from table2 only.[code]
View 3 RepliesWe are presently developing an application, let's call it APP1, which uses a SQL Database which have about 800 stored procedures, 600 tables, etc. APP1 was originally created in order to replace another application, APP0, from which we do not have source code but only SQL tables, Stored Procedures, views, etc. Previous programers of APP1 used some DB objects from this same database and added some other objects specific to APP1 because it becomes bigger than APP0. And we do not need APP0 anymore as APP1 does all what we want, and more.
So, now, we are thinking about a way to find out which objects are used by APP1 in order to remove objects which are ONLY used by APP0.What is the best approach to discover all objects used by APP1 without having to open every single class and form?
Once we will have a complete list of these objects, it will be easy to use a program we bought which detects all dependencies for all SQL Objects specified directly from SQL and remove objects which do not return from any dependencies. Any ideas of how I could get this list without having to go through all our program that have many, many, many classes and forms?
Note : I know, in a perfect world, all calls to PSs and tables should be in a DAL but in the case of the application we're presently working on ... this is not our case! Yippy! (sarcastic yippy) ;)
Note 2 : This application is not using any ORM. So all queries are directly using SqlCommand. So any call to any DB objects are in string format.

I have two tables < student > and <class> . In vb2008 i make the connection to the database, display the data in both tables, edit existing data. The problem is that when i try to insert new rows to both tables there is a problem when i try to save both tables at the same time. The save button is in the studentBindingNavigator. I connect to the db through the Add New Data Source. The message i get is Can not insert or change a record beause it requires a relevant record in table student. Does anyone know anything about it?The two tables are related to each other.

I've been working on a project for the last couple of days and have come across a problem that I'm sure is easy to resolve, but obviously not for me.
My dataset has a small crossed-out circle that's appeared next to the associated tables. This is preventing me from dropping tables onto the design of my form. Oddly the crossed circle only appears when I'm in the design of a form and not at any other time!

View 1 RepliesI'm trying to populate an Access Data Table (5 columns) with a Visual Studio front end, but I'm not clear on how to pass the data through the parameters. I have created a connection, a data adapter, and a data set in the project by dragging them onto the form. I know the connection works because I can see my Access database using the Server Explorer. I have an INSERT command in the data adapter and the parameters are represented in this command with question marks. See my insert command below INSERT INTO tbl_ConstraintLogs (ConstrinatChangeReason, ConstraintTagName, ConstraintValueBefore, ConstraintValueAfter, onstraintTimeChange) VALUES The values that I want to pass to the database are coming from text boxes or they are program generated. For example: If I have a variable in my program called "AbcValue", how do I get the value of this variable into the database as the first parameter. I was trying to use the "Fill" command, but I'm at a loss here.
