The form it is on is frmMidwest.vb, the database is MarchMadnessDB, with the table being tblMidwest and the column being Username. I am trying to get it so when the user loads frmMidwest.vb it will then check the database to see if the user has entered their picks and if they have it will load their picks back into frmMidwest.vb if the database cannot find their user then it needs to add a record to the database and allow the user to enter their picks. I have already established this with
TblMidwestBindingSource.AddNew()
But if the user exists I do not want them to be able to enter another record. The primary key in the database is the username.
I have a textbox for searching a database. When the text changes it runs a functioncFilter() and loads the records. It is set up to search different columns of a database, and it unfortunately only the first record matching is pulled from the database. Example: when the database contains two people (Bob Smith & Bob Smitt) the user can type the name in the search field. However When the user types Bob Smit it only returns Bob Smith and not both names in the database. I want this to act as a filter, dynamically changing the last with each additional letter typed in the search box. Below is my source code,
Public Sub cFilter() Dim myConnectionstring As String = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & My.Settings.dbLocation & ";Persist Security Info=True;Jet OLEDB:Database Password=BCFAdmin")

I have sucessfully written in excel VBA. The idea is to used the textbox1_change event to find a match in column A of table and once it finds the record, return the value of column B as label1.text. [code] In VB 2008 it's a lot different. I have set up the form the same way with the textbox and labels. I have made a dataset with (1) table (Table1) with (2) columns. Lets call them column A and Column B.I have added the dataset as a binding source to the form and also a table adapter. I also have a standardized query made for the dataset with a very simple SQL statement "SELECT Column A, Column B from Table1"..In order to get the user input to start searching Column A I assume under the textbox_change event i would put something like: [code] I'm getting a bunch of errors of course. Would somepne be able to give me some direction?
My application will start (dataset filtered by username/date) and if it's the first time the user has used it today it will be a blank entry form because there is no record for today created. The user can just type data into the blank form and close it. On the form closing event I want it to run a tableadapter.insert(username, date, x,x,x).
If it starts a second time it will load showing today's entry because today's date was inserted previously when they closed the form. So this time when they close the form I want the form closing event to just run a tableadapter.updateall(dataset) command. I need some help with my form closing event...
I'm creating a rewards system for school where pupil earn points for good behavior which they can then use to purchase things like a packet of pens. (They can also have points deducted for bad behavior). I've created all the forms and now its just getting the data in from the Access database. This is what I need to do. On my form called detailsPupil it shows various information such as Name, email address, last login etc. This form is loaded once the pupil has logged in.
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click Dim Login = Me.StudentTableAdapter1.UsernamePasswordString(txtUsername.Text, txtPassword.Text, cboPermissions.Text) If Login Is Nothing Then MsgBox("Incorrect Username or Password") [Code] .....
That all works but I'm having problems working out how to get the information like Name and email address into their places. This is what I have so far on my detailsPupil form. Public Class detailsPupil Private Sub btnLogOut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogOut.Click Login.Show() [Code] .....
So to sum up I need to run a query which searches the DB using the Username which is obtained from the login form and then displays the Student Name in txtName, Email address in txtEmail etc...

The system should not insert selected records from my datagridviewcheckboxcolumn if it's already existed in the database.It's like when you're registering online. If you're username/email address already registered,it would inform you that youre username/email is already registered and the site would ask you to change your username/email to new ones.The difference in my system is that i have 2 datagridviewcheckbox columns not just textboxes . Parent and Child in the datagridview. What i want to happen is that once the Code has been registered as Parent it cant be registered again as Child anymore.
