I call this stored procedure using a web service.i manage to show all the column names in my combobox but when I want to click a button and insert selected column name into a richtextbox I get System.Data.DataRowView in the textbox instead.
My code:
'the combobox
'if I don't have this textblock all the values are shown vertical instead of the normal horizontal lines
'the stored procedure
SELECT COLUMN_NAME
[code]....
how to get the selected text in the combobox to the richtextbox?

i have a very simple problem but i can't figure how to fix it.I'll explain, i have 3 array named "Auto, Legumes, Films". I i making a function so whenever the selecteditem of the combobox change(Auto, Legumes or Films) the name of the selecteditem is passed to a function. The function use this name to display the items of the corresponding table in a listbox.The 3 different item name in the combobox match the name of the 3 tables, so i want to be able to re-use the name dynamically in my function.
Code where i call the function:

Basically the application I'm creating has a login screen with two textboxes and one ComboBox... Once the user enters their first and last time for the first time it'll be stored in the combobox's index..Now my issue is this... Originally before I implemented the combobox the related user file name would be:"C:FicheStatsJohn SmithJanuary" + Ttbox1.text + Textbox2.text + ".txt"So basically the user filename would be JohnSmith.textBut now I want the user to directly select from the combobox and that the file name remains the same without space.... but in the combobox the name appears as John Smith.>

I'm using VB 2008 express to create a windows form application. I have a combobox named cb_face. The items in the combobox are image file names populated from my resource folder using a "for each" loop. When an item is selected I would like to display the image in picturebox1. I have tried several different codes but none of them display the image. I am not getting any errors. The comment lines show some of the code that has been tried.

My question is, the SelectedItem property of the Combobox is supposed to return a integer value, is it not? Because I am getting back integers, sometimes, then the next time through I get back a String. Has anyone else had a problem like this with the Combobox?

I have a database with table "Customer" that will be the datasource for my form controls. My form has a combobox and various textboxes that need to change based on the selectedvalue in the combobox, cboCustNo. Firstly, I'm try to get the combobox to populate with the customer names on the table but have the value member of the combobox set to their customer numbers (just for ease of indexing). Based on the user's selection I'm trying to have various textboxes show the corresponding data (Address, City, Balance, etc.). The code I have so far is below:
Dim cnnDB As New Data.OleDb.OleDbConnection
Dim cmdSelect As New OleDb.OleDbCommand
Dim rdCustomer As OleDb.OleDbDataReader
Dim CustTable As New DataTable

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.
