I have created an auto emailer to distribute our work routes for my colleagues. Problem is I made it easy for the management team to update the list. List is ordered by Tech Number, First name, Last name, Email address.
I have coded this in VB.NET 2008 using Database sources and drag-n-drop the table on the form. I let VB do most of the coding of the connection and text boxes. (IE If (Tech_TextBox.Text <> "9999") Then)What I would like to do, instead of using a bogus tech number as an exit. I need an 'IF Then" or 'DO UNTIL' after last record.

I am creating some basic software for our manufacturing department. I am using Visual Studio 2008 using Visual Basic.The software has a user log in. There is a form in which the choose the worker name, the item they were making, how many were made, damaged, or received damaged from the supplierHowever when they click on the "Update" button to insert the record..i get my custom message that it failed and the record is not inserted. I put a TRY...Catch... around the insert query and it didn't generate an error message.I have been following the code in the OLEDB BASICS tutorial so I am not sure what the problem is at this time.

I have a windows app that has a bindingNavigator connected to BindingSource that connects to an Access database. I am manually adding a record to the underlying database using an OLEDBConnection/command (cloning the current record). The insert into the database works fine, what I am not sure on how to do is force the bindingNavigatgor to refresh and read the new record and refelect it in the record count/next/previous buttons.Jack

I can not seem to successfully update the Access database from an edited DataGridView. I am trying to use Stored Procedures that are in the Access database and work fine therein.

I've recently made another question about connecting to MS-ACCESS database with .NET in C# or VB.NET. It worked just as intended with MDB, but with accdb it caused an exception in
conn.Open();which follows:
Is there another way to do this? My original intention (like stated in the original question) is gathering some (actually, a lot of) fields.

I am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?

This is the code in my button which adds a new record.

'This try statement checks to see if a row has successfully been found

I'm at another wall in my project. I've been trying to get it to add a new record to a table but I got a message that said "Object reference not set to an instance of an object" but I have no clue where the error is popping up. I am also unsure of whether the coding for adding a record will actually work on not.Here is the code for the form with the bits subs that I'm sure aren't the problem removed (as they have no relevance to adding a record);

We're trying to work out some code for saving from a textbox to a database field without using DataGridViiew. We have it working using the automated controls that Visual Studio gives us, but if we have a form with text boxes, can we make it so that, on a button click, it dumps that stuff into a field in a table?
