Get Two Different Tables In Database?

Mar 7, 2011

I've got two different tables in my database. One is Class and other one is LAREACT and both of them have a key field of MAIN FACILITY USED. In the following part of my code a DataTable will be generated based on the sum of the records on both tables.Based on the bellow code ACTIVITYLOOKUP datatable is having "MAIN FACILITY USED","Description","TypeName","Type","Id" columns. The issue happens when there is a row with the same MAIN FACILITY USED entity. The datatable will not show it (filter it?). Do you know where the problem lies? and how it will be fixed without any modification in database?

Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays

Jul 25, 2012

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

Bound To Tables In A Sql Database?

Nov 7, 2010

I have a form with 3 datagridview controls that are bound to tables in a sql database. When the form loads for the first time the data is displayed correctly. If I add data to the db on another form then show the first form again the data displayed does not include the new data. If I close the app and then open it again then the new data is displayed.I cannot figure out how to manually refresh the gridview. I have tried calling the fill method of the adapter, using the refresh method of the gridview and parent control and form with still no luck. I have a ASP.net project I'm working on also and it is so easy to refresh the sqldatacontrol and the gridview and I would have though a win form would have been just as easy if not easier.

Database With Multiple Tables?

Mar 26, 2009

how to create a local database, create some tables and set relations between those tables (just like in access) and I can show, add, edit and delete that data from a form.

but what I have yet to figure out is if I have 2 tables (i.e: tbleName, tblFood) and I want to have multiple tblFood items show for every 1 tblName item.

I've found that if I add a txtbox of the name table and a datagrid of the food table, the datagrid view shows all the food records, not just the ones for the name txtbox.

Bind TWO Different Database Tables To ONE Textbox In VB?

Mar 20, 2011

I was wondering if there is any way to bind TWO different database tables to ONE textbox in VB? I've spent the whole day going through tutorials and different webpages and I've found nothing at all on this...

Well let me try to explain what I want to do exactly: basically I have multiple buttons on 'Form 1' and a textbox on 'Form 2' asking the user to insert a value which will then go to an Access database. But here is where it gets tricky for me: IF the user presses Button 1, the Value inserted on Form 2 will go to a field in the database whereas if the user presses Button 2 to open Form 2, then the value will go to somewhere else and so on.

This would be easy to do if I was to create multiple forms or multiple textboxes, 1 for each button but what I really need is 1 form/1 textbox that would work for all of them... [URL]

Adding Tables After Database Selected As DataSource

Dec 8, 2011

I know this is a very basic question but it has been awhile since I created a project with a database( been using a lot of XML). I created a database then selected it as a data source added some controls to some forms. Then I realized I needed to adjust some tables and I needed to add a whole new table. I deleted the controls and updated the tables that needed some adjustment. Now I would like another table. Can I disassociate the data source and do my adjustment to the database?

Have I created a problem with the binding object since I just deleted the controls on the form. I have written classes and some logic or else I might just start over. I guess I could copy those files but I am wondering if there is an easy way to fix what I have started. I realize that there are alot of questions here so any resource on how to modify a database that is attached to a VB.Net project.

Best Practice - VB Projects - Using Such A Large Database With Many Tables

Feb 21, 2012

The Adventureworks database is used extensively for tutorials in Visual Basic applications. This has many tables that can be bound to a solution. What I would like to know is, when using such a large database with many tables and using lots of them, is it better to construct your program with a number of projects all under one solution or to put everything into a single project. If you use a number of projects, what is the syntax for accessing each module from a menu strip in your main form? I know how to do this in a single project - all you do is Form(x).show. In Adventureworks, you have a table for Employees that could be put into a single project with a number of forms - one for data entry, one for displaying all of the employees, a filter to a single employee, etc., etc.

If two small projects rely on each other for some reason, again the syntax for linking them could be an issue. Would it be better to combine them into a single project? My reason for asking is that I would feel safer if I created an application on a project by project basis and then brought them all together in one solution. This way they can be tested individually and then linked together where necessary. Making a disastrous mistake in one then only requires a small re-write rather than the headache caused by a total crash of the whole solution. I would like to know which option professional developers take. I am using Visual Studio 2008 Professional and SQL 2005 Express

C# - Gathering Data From Tables Of Access Database

Mar 2, 2010

I want to gather some data from some tables of an Access Database, I've found some solutions online, but I haven't found ways to fill a datatable, or dataset, and get each single field properly. Is it easier for me to get whole tables then get just the info that i want, or should I make a lot of searches in the access DB getting just what I want each time? Any code snippets for it? The Access Database is in an ACCDB file, with no user or password. I'm currently using VB.NET, but it doesn't matter if you answer in C#. [URL]

Changing field sizes in database tables

I do it like this:

Dim dbCommand2 As New OleDbCommand(strSql2, cn)

This is working, this is how I did it in VB6, but I wonder, is there an easier way?

Would it be possible to change field sizes more directly?

Database - Simple Front-end For MySQL Tables?

Sep 2, 2010

I'm looking for a front-end that's very simple, to access a to-be-built MySQL Database. I actually need it for only one table. I was thinking that the user could search in a way that would ask for values for each field of that table, and give the option of leaving it blank. Then, it would return all the entries that match up with the query.
