I'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.
I want to compress an ms access database using vb.net. If the database is open this fails. How can I close the database, compress it, then reopen the database using vb.net code to accomplish this.

For speed, I've decided to use temporary tables as the recordsource for a report. The problem occurs when I try and tidy up after the report is closed by trying to drop the temp table. Trying to do this using database.execute "DROP TABLE x" where x is the name of the temp table. Get a Run-time 3211 error that the table still has locks. I figured that any locks generated by the report would be dropped at least by the Deactivate event, but that doesn't seem to be the case. how to use a temp table in the report withot incurring an enduring table lock? The report is the sole user.
I used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)

I would like to retrieve the datatype of a specific element from a SQL table. The situation is that I am importing data from a source that does not match column-to-column with my SQL table. The objective is to compare the datatype from my source file to what it MUST be when I write it to my SQL table, and throw an error on a mismatch. I would like to do this without creating a class that contains the layout of my target table if possible.
Here is my problem:I have 2 tables Accounts and Transaction Logs.in Accounts table, it has column "Amount" which is a base amount of an account.and in Trans Logs table, it also has column "Amount" which is additional (add or minus to the base amount) amount of the account.and I don't know how to retrieve that base amount to edit it, then save it back to the table.That means I need to get a value of the right column by using Acc_No to find. I'm using DataSet, by the way.i think it should go like this:
Dim Amount as Decimal Amount = *the code to retrieve the base amount* Amount = Amount + txtAmount.Text *the code to save the new amount back to Accounts table*

I need to retrieve the UserId of the currently logged in user and insert it into table [rms_Report]. I need this to occur after the new record is inserted, but obviously before the response.redirect. I know how to retrieve the UserId, but I'm not sure how to incorporate into the other code.

Obviously doesnt work but the idea is thats the Value i need to put in the Value Column of dtlist In short the project, loops through one table(dtlist) of address's and gets the distances of it from the address's in the second table(dtsold) then gets the higest value from dtsold within a certain distance?
