I have a table called MEMBER with fields for mem_id, mem_name, mem_addr, mem_city,mem_state, mem_zip and another table called STATE with state_id, state_addr, state_name in Access 2007.On the Visual Studio 2008 form, there is a combo box for the state. The goal here is to display the state abbreviations, but use the state_id value for the mem_state (there is a foreign key between those two fields).The mem_state is defined as number, the state_id is autonumber. Under the mem_state definition in Access, I used the lookup wizard (on the database that is in the bin/debug folder) to set the following properties:
Display Control - combo box,
Row Source Type - Table/Query,
Row Source - SELECT [State].[state_id], [State].[state_abbr] FROM State ORDER BY

I have a class project that supplied me with an Access 2007 DB. When in VB and go through the steps for creating a data source. When the Wizard comes up I click on Database, Next, New Connection, Data Source is Microsoft Access Dagabase File (OLE DB), Browse to Database File Name, Test Connection is successful, click on OK, then Next. A MSVS box appears "The connection selected uses a local data file that is not in the current project. "Would you lie to copy the file to your project and modify the connection?"I am supposed to click NO. When I do I get this "Wizard Form" "An unexpected error has occurred. Error Message: Cound not load type." I need to be able to go to the next part of the Configuration Wizard that says "Choose Your Database Objects" I evensaved the file as Access 2003, and it will not work.

I would like to access to a SQL Server Database from my Visual Studio project.
I have SQL Server 2005 Express Edition installed on my PC and I have a database with some tables.
In Visual Studio, I open the Database Explorer and I try to create a database connection.
The Add connection dialog box proposes to enter a database *file name* but I cannot select a database *server* and a database *name*.
Perhaps, is it a restriction because it is a free version ?
Within Visual Web Developer 2008 Express Edition, I can select a database *server* and a database *name* !
check the problem inside my code?

I have created a data source connection to an access db by using the wizard in vs2008. I have then used this as a data source for crystal reports. My user would like to put the database on a network and reference it there. Is there a way to set a new path for this data source during runtime?
View 4 RepliesVisual Basic Project - Student Check In Form using an Access database backend This form needs to draw information from an Access database containg tables for STUDENT, INSTRUCTOR, and SECTION. These all need to have primary keys and ids. When (the user) clicks on the drop down box that displays all the sections:
{Table Tennis 1, Table Tennis 2, Table Tennis 3, Billiards 1, Billiards 2, Billiards 3}This should populate the listbox or datagrid from the STUDENT table with the Students that have the same SECTIONID as the SECTION selected in the drop down menu above.
After the Student list has been populated (the user) clicks on a student name in the listbox/datagrid and this inserts that student into the CHECKEDIN table that has a datagrid/listbox associated with it.
This is a great project to practice connecting a database to Visual Studio 2008 .net and playing with the data that has been pulled in. You could use SQL instead of Access.
I basically want to make this in my application, so our technicians have an easier time installing our software. So far, I made a form with 4 text boxes: Server name, user name, password, and a combo-box to select a database.Everything was pretty easy until the database selection code. Microsoft's wizard is very efficient, there's no wait time when the database combo box is being filled.[code]That code gets the databases just fine, but obviously if an exception happens the whole screen locks up and it might take a while to recover depending on what the database error is. My question is, can I make mine just as cool/efficient as Microsoft's?
