I'm 100% sure this is going to be something really simple but I'm using a dataset to update a table which works fine until I ask it to update using data from a textbox.
So this won't work:
Dim updateCMS As New AdminCMSTableAdapters.AT_CMSTableAdapter
updateCMS.Update("Home", "Home", txtHome.Text, 1)
But this will:
Dim updateCMS As New AdminCMSTableAdapters.AT_CMSTableAdapter
updateCMS.Update("Home", "Home", "Test", 1)

In Edit mode, when I check unchecked items, the Update works correctly, but when I clear the checked items, the items are still true in the database. My textboxes and dropdown lists all work as expected. The related code is below. Why won't the cleared checkboxes write to the db? When I set a breakpoint in the ContactRecordOnUpdating method, the values for the unchecked checkboxes are true (which is undoubtedly why they are written to the db that way).

I'm writing an update statement to update a user's password in the linked Access Database when they input (and confirm the input) of the new password in a textbox on my webpage.
The SQL statement that is being generated is - UPDATE tblUser SET [Password]=[chuck68] WHERE UserID=0000009
With tblUser being the correct name for the table, Password being the correct name for the field I wish to change and UserID being the linked field to lookup the password from.
The entirety of my code is as follows: (with the necessary import statement at the top of the class).
Protected Sub ChangePasswordButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ChangePasswordButton.Click

Currently I run 2 separate queries to update + retrieve a tickent number. What happens if there're 2 users clicking on the same button at the same time? Could somehow two updates being run first and then both users get back the same ticket number?
string mySql = "UPDATE TicketCounter SET TicketNumber = (TicketNumber + 1)";
OleDbConnection myConnection = new OleDbConnection(accessConnStr);
OleDbCommand myCmd = new OleDbCommand(mySql, myConnection);
myCmd.Connection.Open();
myCmd.ExecuteNonQuery();
mySql = "SELECT TicketNumber FROM TicketCounter"
myCmd.CommandText = mySql;
OleDbDataReader myReader = myCmd.ExecuteReader();

I have an update panel and data list. Data for this fields are loaded from database (to the textbox).
The save button should write data to database, unfortunetly it dosen't. Instead are loaded empty data. I think The reason is that the textboxes are inside updatepanel.
I tried to make an attempt to with Label. Data where to show from the textbox, instant i have an error:
Object reference not set to an instance of an object.
