I have some text boxes in my form that takes data and saves the data to the database. There is a combo box at the bottom of the page that loads data from a specific field of a database. when I enter and save the new data (using the textboxes), the combobox doesn't show the newly entered data. I tried to refresh the combobox using code like combobox.refresh, me.refresh etc, to refresh the form but nothing is working the combobox only display the new data when I close the form and reload the form again. anyway, the data loading in the combobox is done using datasource, displaymember, valuemember in the properties. So, how can I make the combobox show the just added record (field)?

I have a combo which contains a lot of different colours. If I press b it goes to the b's in the list and if I press it again it goes to the next b. Is it possible to jump to the colour as I type it so if I type blu it would go to blue. Currently it jumps to the first b when I type b but ignores the lu for blue.
I was wondering whether it's possible to change the highlight colour for a combo box without having to create a custom control? Just to try and make what I'm asking clearer, it's not the ForeColour or the BackColour that I'm wanting to change but the colour that's shown by the mouse when you move it over the combo box items.

i have a combo box that i'm trying to fill from a database, managed to get it working through the wizard and the form view method but could do the next bit that way. I then started to try it the coded way, got the database linked but it only shows the first name in the database, how do i get it to show all the names in the database?
this is the code for the form

PROBLEM: I want to only show specific database records based on serveral combo-box inputs from a user. I'm looking to query an Access database from within a form I've created for viewing simple Jpegs of CAD files and pointcloud data. I've never worked with table adapters, SQL statements, or much in the way of databases before and I'm lost.
Do I add a new query and do what I want from a configuration wizard somehow? That method gave me a toolstrip button with no combo-box.Should the combo-box be bound to the table or should it stand alone?Can this be done without the use of a wizard (purely in an event) I've been told what I'm looking to do is rather simple, I'm just unable to find syntax that has worked for me.
In my Visual Basic application I have added a Access 2003 Database to the Data Sources. When I drag and drop the table I want onto the form in Details view, it all appears very nicely with the added bonus of a Calendar selector thing for the field with a Data Type of Date. However I have used some Lookup Wizards while setting up the database in Access and they appear as Text Box, how can I make it so they appear as combo boxes with the selection from the lookup wizard?
I'm trying to bind a combo box to a Access database field. I'm trying to do this with code instead of using the data sources wizard as I was told that this would be more flexible and better if distributing the finished program to other computers.
The result is that the form runs, but nothing is in the combo box.
I have also not used a dataset in my code, only a data table. Am I correct in thinking that this is plausible?

I'm doing an application which uses the Database Wizard to link the textboxes, labels, and combo boxes to the data base. (Visual Basic in Visual Studio 2008). (Visual Basic 2008 by Shelly Cashman-Chapter 10)There are two problems: One of the combo boxes has the unique key identifier. You are supposed to be able to use the combo box arrow to select one of the unique keys. Every time I click on one of the unique keys to see the records connected to it, VB acts like I'm trying to input a duplicate key. My teacher hasn't been able to figure this one either. If I was connecting the code, I could fix this but I have no clue since I have to use the Database Wizard on how to fix it.
I this application, I am retirving data to fill combo box from database.There is a search buttom next to it which takes that selected and search in database and retieve other data related to it.Now in the combo box, one can also enter data (textfield too).So if the person enters wrong things, I want to display a message that " Incorrect value"
My code for the onclick_search is as follows: Private Sub btn_cylsearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_cylsearch.Click
I have some combo boxes which displays one column of one database, and I want to trigger a query to it every time the CBox is changed, but as soon as the dialog with the cboxes opens, triggers itself..
Private Sub cbProd2_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles cbProd2.SelectedIndexChanged 'MsgBox("Changed") txtQtd1.Text = "2" End Sub
[Code]...
To test it I used the MsgBox and everytime the form opens it triggers the Msgbox 3 times each combobox.
I tried with SelectecIndexChanged and SelectedValueChanged but none of them worked good (I tried both isolated, one at time)
I am trying to trap an error that would occur if the user in my database does not select a category from a combo box before saving the record.[code] Naturally the example does not work, but would like some help with this.[code]Categoryid is set up as not to allow null.type int
