Using the ado.net connect schema you can get the schema from a access database. I can use the alter statement to add a field, but I want to update the descrption and default properties. Can the be done without using adodb or adox (com objects)?

I have a piece of software I am converting to ADO.NET from ADODB. In ADODB I can update a recordset by simply.
Dim rs as ADODB.Recordset
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
OR IF I WANTED TO ADD
Dim rs as ADODB.Recordset
rs.AddNew()
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
I am confused about to easily accomplish this. I know I can use an insert or update command but it would be much easier to do something like this. NOTE: The query just returns a filled RecordSet, it just executes the command and connection without me having to do it all over the place.

View 7 RepliesI'm trying to insert and update from a table in MSAccess I've declared everything: Connection, DataAdapter and Commands.I didn't use the Command Builder instead I supplied my own Queries.My problem is if I add three rows to my table all the three rows in my database have the same values from the first row. It seems like the parameters are stuck on the values from the first row. [code] I'm using a DataTable with my DataAdapter since I'm dealing with a single table.I'm filling the table with a parametrized query, and updating it with the same dataadapter.I'm adding rows to my datatable and manipulating the table through code. I know that my data is there and every row has it's own values, I can see them when I debug my program.
View 1 RepliesI need to edit and add records to a shared MSAccess .mdb file residing on a server (actually a shared Public folder during development), preferably through an OleDBAdapter or OleDBConnection. I've been able to connect and read data from the database, but receive an "Operation must use an updateable query." error when trying to invoke the OleDBAdapter.Update({datatable}) method. The Update method works fine if I move the database (and connection) to my local C: drive, but fails when moved to the shared folder. Eventually, the shared .mdb file will need to reside on a server after development.

I'm converting a VB6 + ADODB app to VB.NET 2010 and targeting both x86 and x64 I understand that ADO is available in both 32 and 64 bits and that .NET supports it.The VB6 code uses ADODB and ADOX to work with OleDb and Odbc data sources. It also uses the Jet and Replication Objects 2.6 library to compact and copy Access database files (if the uderlying database it's using is Access)I'm wondering if I should consider using OleDbConnection/OdbcConnection in the .NET version of the software or stick with ADO.I've looked at OleDbConnection, OdbcConnection and SqlConnection and can see that porting the old code over would be time consuming and risky.

I have an .XSD that is made from a class so that I can pass to a webservice. It got it over to the webservice as an XMLSchema object and now I need to make it into a class so that I can make objects out of it on the webservice side.

I'm a little stuck here and maybe some of you can point me in the right direction ... maybe even get me a solution.

There is an old timesheet application being used in my company and i am going to rewrite it in asp.net.There are other tables which can be linked to new Timesheet table like employee table but my main concern here is the Project and Project_Activity table.In the current system, there is a one project and a activity table which are linked to the timesheet table seperatly and user has to spend alot of time on selecting activities code they worked on for specific project.I have came up with the new idea; Project manager will have to fill up a project template and link all the activities code with the one project before starting this project. This way user will have to select the project only and it will automatically bring the associate codes for them.I like to know if this design will work okay? and is it okay to link Project_Activity table with timesheet?
