When the form loads I want to fill the combobox with the data present in the database. So I did the below
Private Sub BindCombo()
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsF1pracF1pracBank_Account.mdb")
con.Open()
cmd = New OleDbCommand("Select * from BankAccount", con)
[Code] .....
Doing this code the data is added up in the combobox dropdown list. But when I am selecting a data from the combobox dropdown list,the all the corresponding data of the other combobox also get filled automatically. I don't want to let the other combobox filled with their data automatically....

I'm making a custom scripting engine type thing. I'm trying to add an option to where you can select a list of functions from a dropdown combobox. I want it to display the "Display Names"(Keys as String) of the items in the combobox, but I want it the DisplayNames to point to the (Value as String).[code]so I want "Equals" to be displayed in the combobox, but I want "=" to be the real value.

I have a problem when trying to show details of XML file by choosing an item from Combobox. I have two XML files, called Employee.XML & Subject.XML. The format is like below
<Employee>
<EmployeeID> </EmployeeID>
<Position> </Position>
[code]....
The Combobox contains Employee and its Position also (eg: A1 - IT professor). When I choose an item in here, its Subject details will automatically show in Textbox (one EmployeeID can have many subjects). I cannot use Combobox.SelectItem because I already set Option Explicit On & Option Strict On. I also make EmployeeID by ascending coming up with its position. How can I show details in TextBox by using Subject.XML? I tried many methods but none can work properly.

I want to make it so you can type a name into an input box and have it go into your combobox1. Then also have it to where you can load a list of names into your combobox from a text file where the text in the text file would be like this
NAME 1
NAME 2
NAME 3
NAME 4
So it will enter in the combobox1 like that. Also, This is an account maker, So I was wondering how I would make it so after it creates the account it will use the next text, can I just use the "Next" method?

I'm creating a dynamic combo box and adding to a form. I'm trying to fill the combo box with a DataSource from an ArrayList and then selecting an item in the combo box based off a value from a property.Problem is, the combo box items don't get bound until after the Form_Load event has finished and the form is visible. So the combo box is empty when I try to set the selected index of the combo box. See code for what I'm doing in detail, and refer to comments in
[code]...
How to select the right selected index for combo box without a hack (Load timer or something stupid like that)?

I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.
I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.
