I want to display the index number of the selected record in a listview box as it is clicked by the user. I can do it with multiselect set to false and the following call.
Private
Sub ListView1_SelectedIndexChanged(ByVal
sender As System.Object,
ByVal e
As System.EventArgs)
Handles ListView1.SelectedIndexChanged
[Code]...
This works fine except for one thing! after I click OK to the msgbox prompt, the record highlights normally and I click on the next record, and I get an Argument out of range exception error message, where I expected to just get another message with the next record number.

I have two forms. On the first I have a datagridview that is filled with records on the form's load event. When the user double clicks on one cell of the selected row (of the datagridview) I want to open the second form and fill the textboxes with the equivalent data (I mean each textbox must be filled with the equivalent value of the selected record).

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.

I have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have now wasted over two days going round & round in circles with the pathetic excuse for a Help System Microsoft now makes us put up with (& nearly blown my monthly broadband data cap doing so).I have lost count of the links that do not exist.The Give Feedback option also does not work (I do not like Microsoft Outlook, & in spite of having set Windows Mail as the default mail that doesn't work either!).Every VB example I have downloaded has failed to operate as it should (if at all), so surprise, surprise nor does my implementation of what they say is how to do it! please give me the "exec summary" version of what I need, ON ONE PAGE which is: Correct way (& syntax) to (in VB code):
1 Open an existing SQL compact 3.5 database THAT IS WHERE I SPECIFY - NOT WHERE the wizards keep saying it is(it against my instructions)!
2 Search to see if a particular record exists in the database (eg WHERE ColumnName. FieldContents = ContentsImLookingFor)?
3 Retrieve the found record into my own record buffer?
3 Add the record if it does not exist?
4 Change the record?
5 Delete the record?
6 Close the database?
The rest I will do MY WAY, a thousand times faster & more efficiently than anything I've seen "documented" so far. Surely that is not a huge ask requiring GBs of "Help" garbage leading nowhere?I've only been programming for 25 years (but not in this environment),

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...

I have a dropdown list that will add new titles to my database, however I would like to add a textbox that will allow the user to type in a new title if there is nothing in the dropdown that makes any sense for what they are trying to add.
I have the dropdown dynamically getting titles from the database. Unfortunately, this means that the first value in the dropdown list is not a default that says "Select an option." I don't know how to get the dropdown to have the first option listed as "Select" when the values are being pulled from the database. I can't add Select an option to the database so how would this even work?
What can I add to my codebehind that will allow the textbox to insert into the database if the dropdown list is not inserting anything? Right now I don't have any codebehind for the textbox but I do have the dropdown list inserting the correct information.
<li class="alternatingItem">
<asp:LinkButton ID="DescButton" runat="server">Description</asp:LinkButton>
<asp:Panel ID="DescPanel" runat="server" CssClass="modalPopup" Style="display:none">
<div class="PopupHeader">Add a Description</div>

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?
