I need to pull from an access database to populate a combobox. Then from there I need to have a second combo box populated depending on the selection in the first box. My thought of an example would be a website that is setup for selecting car make, modle,year...can that be done in VB?

I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box called SelectYearMonth that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
When I made a report in Access using VBA I coded my calculation as:
Me.ExactReprintTextbox = DSum("Pages", "HBELP_FINAL_Q", "YEARMONTH = " & [SelectYearMonth] & " AND JOBTYPE = 'E'")
While this works great with Access VBA, this syntax does not work in VB 2008 Express. How do I code this in VB 2008 Express?
I need to calculate the sum of all "Pages" of a particular "JOBTYPE" in the Access database for the YEARMONTH selected in the combobox. I have a query in Access called "JobTypeExact_Query" that contains all the pages of that particular JOBTYPE that I need. What I need to do is limit the calculation results to the YEARMONTH selected in the combobox.

I am trying to populate my combobox from Access, I decided to use a function in a separate module to connect, querry and return the result to my combobox for the sake of diminishing the number of lines, but I can't get it to work in .net.
Here is the module I modified from what I found on the net:
Module DataModule
Dim cnn As Data.OleDb.OleDbConnection = Nothing
Dim DBpath As String = My.Settings.SDBPATH
Dim SQLString As String
Private cnnOpen As Boolean = False
[Code] .....
I remember .eof method for my "While Not" loop but I can't seem to make it work. Basically the table in my DB consist of 2 columns, the first being ID (autonumbers) and the second are the records I want to access via my combobox, there is about 10 rows for now but it is subject to change.

I want to populate a combo box but not using a database
e.g. combobox displays
red
white
blue
But want I want is if a person chooses red I want to pass back the number 1 value to a backend database. I'm able to populate a combo box with the colours but not sure how i 'grab' the value to pass back
Dim colours as string[] = new string[] { "red", "white", "blue" }
m_cmbColours.Items.AddRange(colours)
What I want is this
value Colour
1 red
2 white
3 blue
Combobox just displays the colours and when chosen in the combo box I grab the value corresponding to colour chosen.

The below code is a sample code that is supposed to display the months in a combobox.
Dim months() As String = _
{"Select a month...",
"January", "February", "March"}
[code]....
But what am I supposed to do with this code? I have created and named the combobox "cboExpirationMonth", but where do I put this code? I tried to put it as a click event of the combobox, but that doesn't work. I created a button and tried to put the code in the button's click event, but that still doesn't populate the combobox.

In this windows forms app, I have a form with six comboboxes. Two are parents, one with a single child and the other with three children. All of these work beautifully except for one of the children. The code for each one is identical, and I've verified the query against the database a dozen times. I even have another of the children that is in the very same block of code. One works beautifully, the other one refuses to populate any data. Below is the code for the one that doesn't work. I would tell you on what line the error occurs, but it doesn't throw any errors. Try catches show nothing, and I have VS 2010 set to throw all errors, but I get nothing, just an empty combo box where there should be a list of names.

Is there a way in which I can populate my listbox with an Access (.mdb) database and search for values in it. Also, can I move selected values back & forth from that listbox to another listbox (or textbox). Is this possible using Visual Studio, VB.Net?

Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.
What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

I have an accdb named base.accdb in the root folder of the program. Basically I have several tables in my database and I need to show their values in listboxes (essentially allowing menus to be edited by adding/removing items in the table)I can't figure out how to connect the database (according to my friends/classmates), and i can't figure out how to pull the information from the table.
Ultimately, it would be nice if someone could tell me how I can pull out the information into maybe an array? so that if i add 3 items into the table, then it will create 3 variables in the program and put the values from the table into those variables.

I have a form on which I want the user to be able to select a name from a list. The list needs to be populated from an table in my dataset. I'd like the user to begin typing and have an autocomplete append select type feature let them zero in on the person they want as they type. My question is, what type of control would work best for this?
