How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields.

View 2 RepliesI 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'm trying to populate a combo box with a dataset, this sort of works, but everything is just appearing on the same line. I think this answer might be to put the dataset into an array, then put the array into the combo box.
...problem is, I'm not sure how to do this! My code thus far is,
Dim usernameList As Array
'Retrieve usernames where player has available status
GetFilteredData()

I am currently stuck in one part of my application. I have two combo boxes that i am having the users select from. The first combo box is simply bound to a datatable. that is working properly. The second one i need to populate off another datatable after sorting out what the first one is requesting. Basically it's choosing a line number on the first box and then selecting the machine associated with that line number.[code]...

View 2 RepliesI'm trying to populate a List Box or Combo Box (either or, I feel like both would be very similar in how the code is written) when you load the form. Here is what I have right now:

When you first open the program it gives you a form with either a list box or combo box (not sure which one I want to use yet) and then an add button to add a name to the list. It shows the from where you enter a name and then when you add a name it adds it to a text file that I have saved onto the desktop. It keeps the names on separate lines and I want each line in the text file to be an item in a list box...
Here is the code for the first form:
Public Class frmEmployeesMeat
Private Sub frmEmployeesMeat_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
frmHours.Visible = False
