Search Or Get User Data From Access Database (Tables)?
Apr 17, 2011
I have a form with 5 fields(inputs). When I entered data in the form and click submit, the data is entered into an Access 2007 Database(Table). All the set up (connection) is working because the data table is getting populated with the user info. However, I also need to search the database by entering a name in the name text box and clicking a button.
This is suppose to populated all the fields with information from the data base if the user exist. The search part is not working. I have no more hair to pull. :) Here is the code:

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]

I've created a basic search form. I have a textbox with a search button and an Access Database as the backend. I have also added it as a new datasource. What I'm looking to do is grab the search string from one textbox and return the data to another textboxt. I have a table called "VehicleInfo" and I want to search the field in my table called "VehicleID" and return the vehicleID I searched for into another textbox. I'm really new to VB. I understand databases and basic code structure, I just don't have a good grasp yet on how these two work together.

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

My problem is that I need to use a access database as a backend for my visual basic.net program.
The database will be accessed by a maximum of 10 users but I want to lock tables when a user is updating a record.
I am unable to use the SQL server at the company due to it storing sensitive information.
I have some basic knowledge of ado.net
I have read many articles but I can't find any articles that say how to lock a access .mdb file using Visual basic.net

I have a database that has tables in it. Tables can be added to this databse programatically as well as the data that needs to be in those tables.I need to be able to query that database to get what tables are in it, place the names of those tables into a listbox so that when a user clicks on the name of the table, It will update a DataGridview with the data that is in that table in the database.I assume that you would need to build a dataset at runtime based off of what tables are in the DB, but i have no idea how to do this.

I have never worked with datagridview before. I need to know how to use it so i can use it in my (calculator) program. I would like to know how to make columns, rows, linking the cells in the table/grid to textboxes so values entered into the textboxes (on the calculator) after pressing save goes straight to the table.

I have a system that gathers raw data from electronic devices, uses that data to populate a set of tables and allow uses to add/edit certain data and report on it. (Kind of basic right...NOT) There are 3 applications that I've written that use the same database.
One is a client that is on 3-4 user machines which allows them to see the data that has come in and work with it.
Two a Data-to-Information process program which takes the raw data, checks up certain information and puts the results into the database.
Third is a data gathering app that interfaces directly with the electronic devices and about 10 times per day places the raw data into a single table in the database.
If a user is in the 'client' application the data processing application crashes all over the place:
1. Database file already in use.
2. Unrecognised Database format
3. File locked exclusively by User on PC X.
Almost always on a different line of code and once when I made it retry over and over I managed to corrupt the database and had to Compact and Repair it to fix it. If no one is using the client everything works perfectly. On each client machine is a database with linked tables to the server machine. The machine that is running the Data processing is the server and the processing is using a database in a different folder that also has linked tables.
I have gone through all the recordsets in the Data Processing application and made sure that they are only using ForwardOnly and Read Only. They edit the data only with Insert, Update or Delete queries. I'm about to do the same in the Client Application as it seems to be the one that is locking everything all the time. The client machines haven't crashed on that error at all. Does it matter which version of Access is on the client and server machines? (All the clients have Access 2003 and the server has 2007 but the Database was created in 2003). Should I just convert the Access database to SQL server and be done with it?

I have three tables (Supplier, Product, PurchaseOrder) within a MS Access database. I am trying to display Product table in DataGrid1, Supplier in DataGrid2, PurchaseOrder in DataGrid3. What I am trying to do is to choose a product, the total list of suppliers for that product appears in DataGrid2. Up to here works fine. Now I want to add the third datagrid so that for product #1, supplier #1, there are four purchase orders listed - default. Then if I choose product #1, supplier #3, there are two purchase orders listed, and so on. I can not find out how to work with the DataAdapters and DataSet Relations for three joined tables.

how to display data coming from different tables in access in a form?...the case is this:
3 tables in access:
AddBook(tablename) - ISBN(primary key), Book_Title, Author
Student(tablename) - Student_ID(primary key), Student_Name, Course, Year
Transact(tablename) - Transaction_No(primary key), ISBN(foreign key), Student_ID(foreign), Date_Borrowed

Im making a search function for an application and they need to be able to search by any value in the DB in any of the three tables. Im wondering the best wayto about this. 2 of the 3 tables have the same columns while the last one is totally different. Below is what I kinda "thought" itd look like but no.
"SELECT * FROM cases, opencases, staff WHERE Crime ='" & txtsearch.Text.ToString & "'"
I need to query the results the user can search for anyterm and if it matches something in the columns it return it to the user. Im wondering if the best way to go about this is to maybe query all the tables and then put all the matching records in a seperate table and the dgv look at that table or how to exactly go about it.

I have written lots of code with the ADO Library in VB Excel and previous versions of Visual Basic. With the dissappearance of the recordset object, how do we perform data manipulation with an attached Access Database? It seems things could be a lot easier, and less complicated by now, however, the best methods appear to currently remain ellusive.

I'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).
