I am using 1 listbox and 4 text box. I want to retrieve data from my database i.e. ms access database into listbox I am firing the select query by using this code on Page Load event and list box selecetedindex change event which is following. [code]...
how i can retrive data from database system(access) and then present it to the user in the form of list box ,so i can select one of them? *retrieved data= only one column from the table
I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String) Try TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
debug this code(especially on the highlighted one, it is where the bug occur)

This is not a homework of mine and i had never tried ms access database with vb so i just gave it a shot. so this is my first time and i am just trying not asking anyone to complete my homework. I have been searching for this a lot on internet but couldn't find a solution to this so i decided to ask this question here. i have this sql code. what i want to do is that create a basic login form where users puts it's username in the UsernameTextbox and Password in the PasswordTextbox. If the the information match then a message box appears saying that the user is valid and if the information does not exist, a mesage box appears saying the users is not valid. now everytime i execute(run) the code, i come up with this error: Syntax error (missing operator) in query expression ''UserName' = 'Admin' 'PassWord' = 'testing123''.
The field names(UserName, PassWord) are also correct they are same as in the database. the information put in the username and password textbox are correct and they match the information on the database. But i dont know why this error comes up.

Imports System.Data.OleDb
