I have a dataset loaded with a table that i needs to be written to the database. how would i write each row of my dataset to my database? Sorry if this sounds a little jumbled together it is late and i am tired. If it is unclear you can ask me and i will answer any questions you have about my question.

Jul 19, 2010I use Visual Basic in Access, and I have no problem writing data directly to a cell in a database table. But I can not figure out how to write the code for Visual Basic 2008. For example I would
use Me![cust_Cost] = 20 to input 20 in the database table.
I have purchased two different Books on Visual Basic 2008 and not one of them show how to input data manually.

Error While Writing Into Access File?
Sep 10, 2011What i've written opens an Access database and one can read and write into it (on a table called Journal)It does indeed work for newly made Access files. However it doesnt work with a specific Microsoft Access database (again .mdb) which was made with a very old Access, like Access 2000 or something.The error message is: Syntax error in INSERT INTO statement.Inside the zipped file below you will find the source code of the program, along with an access file that the program CAN read, and the one access file that i NEED the program to reed but it cannot!
To see what i mean run the program one, try to add a new line to the database. you get an error!now rename the Journal.mdb to "journal.bak.mdb. And the journal_working.mdb to Journal.mdb try to add a new line to the database again without altering the source code at all. it succeeds now!!
NOTE: the program can READ data from both files. but it CANT write data to the old access file
this is the code:
Dim cb As New OleDb.OleDbCommandBuilder(da)
Dim dsNewRow As DataRow
dsNewRow = ds.Tables("AddressBook").NewRow()
dsNewRow.Item(1) = txtFirstName.Text 'or .Item(1) =

Writing VB/Access Apps Fast?
Nov 23, 2010At my company we build a lot of small, administrative type databases generally used by a dozen or less users. We have thus far done them entirely in Access. I've been doing VB forever and would like to write nicer, rich UI apps using a VB front-end to and Access database instead, as I find Access apps clumsy to use; VB apps look better and have more UI options.
I've started to play around with building Data Sources, Binding Sources, etc. and dropping them on forms, trying to create something useful with as little code as possible. I'm just wondering what folks generally think of using this approach. Remember this is for small, not complicated db apps with few users.
I know in the VB6 world bound controls took some heat for being not worth the effort it saved you.Also, is there a good book on the subject that concentrates on creating VB/Access apps with minimal code?

View 3 RepliesVB 2008 - Can't Access MDB Database File?
Oct 27, 2010My problem does not seem to be the same as in other links. I'm trying to teach myself VB 2008 and I want to connect to an Access MDB file. I follow the instructions in all the different books and websites. I start a new project, choose a new data connection, change the type to Microsoft Access and browse for the file. When I get the connection string I press "Test Connection" and it's okay. I then drag either the entire table or just a field to the form. I use Data Preview Data and can see all the rows and columns and the data, so I know the connection has been made. however, when I press F5 I get a form, but no data and it says "0 records of 0".
I accessed the code and put a MsgBox before and after the "Fill" statement. The one before pops up, but the second one (below Fill) does not. I also get "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" in the Immediate Window. I have tried putting a "Try" statement around the code and in this case it will go to the second MsgBox, but still no data.
I'm following what seems to be the most basic and simple method, but I cannot get data in my form.
