Visual Basic 2008 Updates Wrong Record In A MS Access 2007 Database?
Mar 7, 2010
i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:
I'm a software developer and use visual basic 2005 and access 2007.Well first programmed with Visual Basic 6 but I decided to switch to. Net and indeed it is a big step.
Finally, in vb6 did not need the database linked to software to generate reports because it filled from a listview as the connection to the database do it for DAO ("C: ProSoft Billiard Data.mdb"). Now the question is as I can if I have to file a report so the connection in my software? is a bit urgent as I have to give and software and I need to do the reports.
I am using Visual Basic 2008 to create some databases. It reads data from textfiles and puts them in SQL databases. After the user presses the Process button I would like to give the user to get some feedback of the process simply by for example label1.text += "Processing File 2".But during the process no Screen Updates are made...only after all databases are processed and VB.net is waiting for new user response it updates my label1.text
I have created some tables in 2007 and would like to use visual basic to create an interface for a database. I would like to add, edit, and view my records and maybe create reports.
Does anyone know of any online tutorials which would help me to do this or could anyone offer any guidance.
Having problem in updating an existing record. An error occurs "Data Type Mismatch in Criteria Expression"

I would like to be able to read a column of numbers from an Access database into a VB.NET program and then manipulate that data.For example I have a column of numbers and want to add them up and then take the averageThe maths is not a problem but how do I read the column of data into the program. I know how to do this if I first export the Access data into a CSV file, but
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 have used ADOX for create some fields in my database in access but the required property of this appended fields (columns) are set in "yes" but I want to be them "No" who knows how can I solve this problem
I have decided to make a little "safebox", to store some important information. For some reason I have decided to use a database (even though I have never used it!), so I would like if someone could help me connect to the database.I'm not asking for the code (I won't complain if you post it ),
My intention is to load my data from access database through datagridview but it keeps telling me the same error. This is the exact error message I've gotten.. it threw an oledb Exception stating: Could not open table 'MSysAccounts' in the workgroup information file. I've been browsing and viewing different resources but I still do not find a solution to view my data in datagridview. Few things I've tried:
1. I originally uses Ms Access 2007 to load, but it does not seem to work well, hence i converted it into Ms Access 2003 format. Same error displayed.
2. Working around with the workgroup in Access 2003, creating new workgroup which creates System.mdw file and I replaced it in:

My problem is that, whenever i add a new record and clicked the Save Record button, the msgbox "Data Update Failed" popped out. But when i recheck, the newly added record was actually successfully saved in the database.

I have a database called "IMYS" and a "Customers" table in it. What I want to do is: Define a variable like "Last_Name" and retrieve last names of customers one by one. I've tried this before (and, it doesn't work for me):
=== Dim Last_Name as String Dim I, K as Integer Dim CustomersTable = New IMYSDataSetTableAdapters.CustomersTableAdapter
After trawling around the net for a good few days, i decided to post something here.
Basically, i've got a problem linking a data source (Access 2007 database) to a VB 2008 project.
I've broken it down to having a problem dragging a table onto my form, when it generates the nav bar, it says "0 of {0}", and the table is empty (despite the actual database containing values)
However, this happens only at home, at college it works totally fine. The only difference that's obvious is that i'm using Windows 7 at home, and Windows XP at college.
