I'm using ASP.NET/VB and I'm trying to insert a date and time into an Access date/time field, but I'm getting an error (Data type mismatch in criteria expression). Here's a simplified version of my code:
Dim myDate As Date = Now()
Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (date_submitted) VALUES (?)", myConn)
myIns1.Parameters.AddWithValue("@myDate", myDate)
myIns1.ExecuteNonQuery()
Not sure why I'm getting the error, and not quite sure if this is even the correct way to approach inserting the current date. From looking at other similar questions it appears there are a few different ways to do this, but my technical knowledge is kind of limited so I'm having a hard time figuring it out (in other words deciphering the answers that use technical terms I know nothing about).

Im trying to use DateTimePicker function and save the date to an access database. Everything is working somewhat how I want it to but not 100% yet. Here is my problem. When the program is running if I click on the datetimepicker and select a date and click my save button the date IS saved to my access database as it should.
but if i run the program and don't ever click on the datetimepicker (because it is already on the correct current date) and click my save button the date doesn't get saved to the access database. The closest I have gotten was to enable the ShowCheckBox option, If i run the program this way and select the check box but dont select a date then it will save the date to my db.
But I really need it to be able to save the date to the db without the user ever clicking on the datetimepicker. Is it just a simple line I'm missing? Im pretty new to this but Ill try to explain anything the best I can if you have any further questions for me.

I have a VB6 application which has been running succesfully for years under XP, however under Vista data loss has been observed.It appears that if the app is run 'as administrator' then it connects to the correct database file, however if the app. is not run as administrator then vista creates a copy of the database (no idea where) - hence I end up with 2 versions of the database.
In fact I can delete the database file entirely and the app. still works fine because vista is using it's own copy - the problem is how do I back up this 'vista copy' when I can't find it (search doesn't find it).

I have a VB 2010 program with a single-table Access Database.I have selected the option to copy the Access Database to the output directory.When doing so, the program copies the original database to the inDebug folder.I want the original (NOT the copy) to be modified when the program is being tested.Also, when I attempted to publish the program and run it to test, I got an error which was sourced to be a temporary file (which was the database) that was missing.I think this is a reaction from the "Copy Always" option.

I'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.

I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

I have a database that I would like to filter characters from anywhere in the field. Example the letter A is typed into textbox1 and in the grid every field that contains an A is show. Like dash, lap, trap, apple. Currently with the query I'm using it will just go from the beginning of the field. I get "Index was outside the bounds of the array". The code is as followed:
Dim filter1() As String
filter1 = TextBox2.Text.Split(" ")
Sheet1BindingSource.Filter = "Stationary_location like '" & filter1(0) & "' Stationary_location like '" & filter1(1) & "'"

I need to add a new field to an Access database table, the user has filled the table with data, so I have to add the new field but to preserve the old data.
I have found the ALTER TABLE statement, but it gives me an error (ALTER TABLE is not a valid statement)
I done this in php+mysql with "ALTER TABLE People ADD Address TEXT NULL AFTER Name" (as an example)
How can do this in VB2010?

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I have made a front-end application in Visual Basic .NET that will store data entered by the user in a backend Access 2003 Database. The application has other functionality as well.If the user searchs for a previous record that has been stored in the Access Database, I query the Database (SELECT ... ) using an OLEDB Connection and then display the records on a Datagrid on my Form. Everything is working fine, however, the Column Headings of the Datagrid are the Field Names in my Database (FirstName, LastName,...) rather than Caption Values (First Name, Last Name,... )
I tried looking up the net, but most of the topics addressing a similar problems use DAO, and I understand that it is not completely supported in VB .NET. I am fairly new to VB .NET and I am not quite sure how to address the problem or where I am going wrong. I tried using FirstName.Caption but that gives a Runtime error (One or more parameters missing from the Sentence)

I am working on an asp.net project in VS2010 using vb.NET (not VBA) designing an interface to allow a user to upload a file to an access 2007 table attachment field. My understanding is that in order to interface with a table with an attachment field you
must use DAO to connect to the database so that you can expose the attachment field properties. When I try to open the DAO recordset I am getting "COM exception was unhandled by user code" with a message stating "Too few parameters. Expected 3". The error code is -2146825227 and the stacktrace message is "at dao.Database.OpenRecordset(String Name, Object Type, Object Options, Object LockEdit)"
