I am trying to do simple insert, update, delete, select statements within VB .NET to access a MS Access database. I have tried all kinds of solutions offered on the web and while the code seems to work, no rows are inserted. Also, I have tried, unsuccessfully, to use the Try/Catch to see if there's an error with no success. I have attached the versions of VB .Net and MS Access I am using: Here's the code:

I'm running Microsoft Visual Studio 2010 SP1 and SQL Server 2008 R2 and I'm using vb.net coding. Any other information that you need to know, just ask.I've got a form in a master/ details setup that has one table in details view in the top half of a split container, and another table in a dgv in the bottom half of the container. Everything is working well except for one value. My dueDate value always reverts back to the date set when the record was made, which is the default value put in when a new record is made. It doesn't give me any errors to work off of, and I've even went and coded the update by hand with this code:
Dim Num, Contract, ID, Receive, Due, Notes, Inspect, SO, PO, Entry As String
Num = Order_NumToolStripTextBox.Text
Contract = Order_ContractTextBox.Text
[code]....
All that happens when I hit save is my due date will revert back to the old due date. I have no clue what would/could cause this. I've went through to see if anything that would store the original dueDate (from a check I set up in my coding) is coded somewhere it shouldn't be, but all it does is make the check that something had changed while on the form. it takes an array of all my text boxes and checks it with an array made before leaving the form. Nowhere else is the original dueDate saved.
I am using VB 2005 and the following code returns an error: No value given for one or more parameters. I swear I've done this before without any problems but I can't find my original code.[code]I tested the value of oldid which is set earlier and it does have a value.

I need to select some user datagridview settings (such as column width, column visible, etc.) from my database. Then I run a loop to change those settings. If any settings are changed I need to update the database. For some reason I can't get the code below to update anything. The code throws no errors when it executes, but when I check the database for the updates nothing is changed.

I have my application set up with ClickOnce. It has been successfully published to my web site. I don't have updates performed automatically but on demand. I have a button that the user can click if they want to check if an update is available and install the update if it is. Here's the
[Code]...
After clicking the button a message box appears and says, "Update is available for download" as you would expect but after clicking the ok on the message box my application goes into a not responding state and I have to close it with the task manager. The application builds successfully and I have a reference for System.Deployment added to the project. Everything in my application works fine as long as I don't try to do an update. Any suggestions on what I should check or do? It should actually say "no updates are available for download" since the version of the program that is being used is the most current version.
I use the following statement to position which row to update;
Dim salonToUpdate = (From r In db.Salons _
Where r.StoreID = storeID _
Select r).Single()
If fileDate = #1/1/1900# OrElse fileDate = Nothing Then
SalonToUpdate.LastDownLoadDate = TableDate
[Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace:
exec sp_executesql N'UPDATE [dbo].[Salons]
SET [LastDownLoadDate] = @p0
WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000'
Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?
I want to show in my form, something to show the user that the program is working just wrote a Label, but Visual Basic Freeze during the process and the label it can not seen and there is not signal to know that the application is working.
