I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

View 4 RepliesI fill table data into dataset using Adapter. How to update dataset changes back to Microsoft SQL Server Table. I refer to the following URL, the solution is working fine, it makes use of the adapter.UPDATE to get table updated with changes made to dataset. [URL]
Sample Code:
cmdBuilder = New SqlCommandBuilder(adapter)
changes = ds.GetChanges()
If changes IsNot Nothing Then
adapter.Update(changes)
End If
I would like to know is there any other alternatives besides the one I have mentioned above. Can the alternative supports scenarios such as update existing record (probably based on primary key or defined conditions), insert new record as well delete existing record.

I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
I have an error ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. and I've been trying to solve this but unfortunately I couldn't get the hack of this error. I'm a newbie in dotNet.

I have vb .net windows form application that I want to connect to Microsoft access database using "Microsoft DAO 3.6 object library". My problem is that when I go to Project tab -> Add reference -> COM tab, there should have been "Microsoft DAO 3.6 Object Library" on the list, but for some reason It's not on the list. Then I googled, and found out that the location of "DAO360.DLL" is "Program FilesCommon FilesMicrosoft SharedDAO". After clicking on Browse tab, I browsed to that location, and I guess I added reference on another way.This is the code that I used before for connecting to Access, but for some reason It doesn't work this way on this PC.

I'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.

View 1 RepliesI have a table located in a Microsoft Word document. changes has been enabled in this document. I see that I can get the collection of revisions using "ActiveDocument.Range.Revisions" . I also see that I can tell if the revision exists inside a table using "Range.Information(wdWithInTable) " .My question is this:I really need to find out the "ID#'s" that contain a revision on the "SomeText#" column.So for example, if "Some Text 1" was revised, I need to output "ID-1".I am puzzled as to how to implement this logic. Does anyone know of a way to go about this?
