This is the code
Imports System.Data, System.Data.OleDb
Public Class Form1
Public CON As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source =" & Application.StartupPath & "\bible.mdb")
[Code] .....
I got that Error for
data2.Fill(ds1, "Bible")
Data type mismatch in criteria expression
the combobox1 value is numbers
I tried this code
Dim sql1 As String = "select distinct ChapterNum from Bible where BookNum ='" & Trim(ComboBox1.Text) & "'"
And this code
Dim sql1 As String = "select distinct ChapterNum from Bible where BookNum ='" & Val(ComboBox1.Text) & "'"
And it still got the same error.

Please forgive, I'm new to Silverlight and am still trying to wrap my head around data binding...
I have a generic list obtained from a class using LINQ. The list has 4 objects, each object consisting of a Letter property (string - A, B, C and D) and a corresponding Number property (integer - 1, 2, 3, and 4).
In Silverlight, I have a combobox control and a text block. I'm trying to figure out how to:
Bind the combobox to the generic list so that the letters populate the combobox.When the user selects a letter in the combobox (say C), the corresponding integer value (3 for this example) is displayed in the text block.

VB 2008 .NET 3.5. I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment.
My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc.
I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment."
In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use.
I have tried a few ideas, but none of them work properly.

In .NET which data type do you use to store list of strings ?Currently I'm using List(Of String) because it's easier than Array to manage and add/remove stuff. I'm trying to understand what are the other options, when they become handy and when I should avoid List(Of String) usage.

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

Ok i'm trying to declare a global list of type T (or is it <anonymous type>) i declare it in a module with something like Friend query As New List(of {whatever type i try}) the app takes some xml and parses it into a list but i need this list available to other classes and methods within the app, everything i have tried fails resulting in an error like Value of type 'System.Collections.Generic.List(Of <anonymous type>)' cannot be converted to 'System.Collections.Generic.List(Of {whatever type i try})'.
What would be the correct way to declare a list of this type? is there another way i could do this?

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]
