I have a Visual Basic 2008 Windows form application that processes some scores and data. I want to export the data to an Access database. I have created the Access database and connected it to the VB program.I am looking for a simple set of commands or sample code to add records to the database. Perhaps I am oversimplifying the problem, but it seems like it should be so much easier than it has proven to be. I only want to export the data in code; the user should never see the database or do anything to it while the program is running.

View 1 RepliesThe apostrophe is used to separate data when adding records to an Access Database data table using the "INSERT INTO" SQL statement. Having apostrophes in the data really screws things up with this new software. Is there a simple workaround? Is it possible to specify a different character? Is it possible to add data without using SQL Statements? I also noticed that the new OleDbDataAdapter Add Method generates the same SQL Error because it apparently creates an "INSERT INTO" SQL Statement.gh

View 16 RepliesFriends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted.

My program has an access database with a table called "Contacts". This table stores many values. I have a seperate table that stores surveys. Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.
contactsDataAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM Contacts", frmAdmin.con)
contactsCommandBuilder = New OleDb.OleDbCommandBuilder(contactsDataAdapter)
dtContacts.Clear()

I have a program for school that links to a database. They are listings of real estate and in the browse of the database I have pictures that can be scrolled through as well. The pictures are added to my access database as OLE objects and then just linked to a picturebox to be displayed. However, I'm wanting to add another functionality and allows the user to upload a picture that can be added to the record as well. But I think I'm having a conversion problem.This is what I have right now that is working...but I would like to be able to change that nothing into something.

Experimenting, I've tried just addressing pictures from my.resources but the errors I get are... "Type System.Drawing.Bitmap cannot be converted into1 dimensional array of Byte". When looking at my dataset as well the datatype for the picture Looks like a series of 1s and 0s.. So essentially I guess what I'm trying to do is convert a picture into an array of bytes so it can passed back?
