Forms :: Searching For Username Field In Database?
May 28, 2010
I have one registration form which consists of username, password, confirmpassword and Register button. When I will be typing the username, it should show whether the username is available or not. And I have changed the username column as primary key in sql database.
Private Sub txtusername1_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtusername1.KeyUp
Dim da As New SqlDataAdapter("select * from Register", con)
da.Fill(ds, "Register1") If txtusername1.Text = ds.Tables("Register1").Rows(0)(0).ToString Then
lblusernameerror.Text = "Username is not available,choose another"
Else
lblusernameerror.Text = "Username is available"
End If
End Sub
In the Bolded line, it is reading only one username but i need to read all the columns. Here I have written key up event in the text box of username, but here it is loading only one username. I am using visual basic 2008 and i am writing the program in disconnected architecture in vb.net.
I'm trying to select a 'Username' value from a table called 'tblUsers' where the 'UserID' is 1 and assign it to the 'Text' property of a field. The SQL command is fine, but I don't know how to assign the value to the file. I've changed the SQL command to select the value I want. I just don't know how to assign it to a field:
'Use these import statements, so you don't have to fully qualify the Oledb Object names: Imports System.Data.OleDb Imports System.Data Public Class Register Function Register() [Code] .....
I'm trying to query LDAP using a field that contain's 's in VBScript, but I can't get it to work. Here is my code (basically). What am I doing wrong?objCommand.CommandText = _
"SELECT cn FROM 'LDAP://" & x & "' WHERE extensionAttribute1 = '1500 0FFEA14C439' "This string will never match any record even if use wild cards or copy in the exact data from the AD record.
There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information DVD Information Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb] SELECT [Member Information].[Member ID] FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.
I have a combo box having multiple items and I want by typing the item should select automatically and combo box style should be "DropdownList" type.Let�s say I am typing "I" then country like "India", "Indonesia�,� Italy" should sort automatically. It is happening by default in VB.NET for one character.But I want If I type "India" this should select "India" instead of "a...." because my last character is a. in VB.Net it is selecting country like starts with "a�. But I want the full typing option should be present for the combo box.

I am trying to create a username database for my program where people create a username when they first open the program and it saves it and uploads their username to an FTP text file.The problem I am having is that I want it to do this and then display ALL users that have created a username on my program and used it in a list on a textbox. I was going to have it do this by having it add all usernames to a text file on my FTP and then have it download the text file of all the users created from the FTP and load it into the textbox on the Form that displays them all.
I'm using Web Developer 2010, ASP.NET with the VB.NET programming language and a MS-Access database (.mdb).What I want to do is get all the data from a table called User (i.e. all the columns) where Username = ____, and then put the values in from the fields into text boxes so they can be edited. This is to make a 'My Account' page so that a user viewing the website can change his address, password etc.
I'm stuck at getting the data from the fields for each specific username.What I've done so far is this, but doesn't work:
I have a small update form for changing username and password of admin..but after clicking on update button the username and password are not updating in the database..it shows no error. [code]...
is there anyway i can search for a particular row in all columns in a database and display them accordingly? like in a customer table, i have CustomerID, Name, Address is it possible to search for all the details of a customer?
I am doing an assignment for class and it is searching an SQL Database file. On the GUI I have a text box and a button to search this database. It is presented on the form in DataGridView connecting to the file, and the file connection test succeeded, I am kinda so so on understanding what is going on with the connection between the file and VB 2008 but I am getting 4 errors: Warning1The designer cannot process the code at line 119: Me.PlayersBindingSource.DataSource = Me.BaseballDataSet
Im trying to input a search box in my forms so that when I type in a customers name it will show there record. I've managed to do it in my transaction form, but not in any other standard forms. In my transaction form I've got this code:
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtSearchSalesID.KeyPress Dim dv As DataView = New DataView()
Where is a good VB.NET tutorial where I can have a username box and a password box and it checks in the database if it's there and if it is then another form will show?
I've created a new datasource dtsLogin containing an ID, username and password. my problem is how can you check if the username & password typed in the textbox are the same as the one on the Access database? I thought maybe using a rowfilter but I'm not that good in ADO.net.
