SelectedIndex : Gets Or Sets The Zero-based Index Of The Currently Selected Item In A ListBox?

Jun 7, 2012

First of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:

When I access the Programing guide, I see that:

ListBox.SelectedIndex Property

Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:

If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then

This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:

' 1. Check if Metric or Imperial Units are selected.
' 2. Convert Entered Variables to opposite unit.

Display XPS Document Using A Selected Combobox Item?

Dec 26, 2011

I am very new to programming, I have developed my first application - an xps viewer. What I want to achieve is to be able to allow the user to select which document to open from a range of options that I have predefined in a combo box. I've searched all over the net and can't find an article that shows me how to do this. MSDN is bit too cryptic for me at this moment, so I get confused.

Getting The Index Number Of Selected ComboBox Item?

Feb 6, 2010

I have a combo box setup with 4 items, with indexes ranging from 0 to 3.

Later in my code, I need to do a certain event depending on what is selected. To do this I thought about comparing what the index of the selected combo box item is, because integer comparison is faster than strings, right?

how I can grab the index of the selected value?

Populating ComboBox Based On Selected Item In First One

Jan 10, 2012

I want to populate the combobox based on the selected item in the first combobox. The following code is written in vb.net 2008

Public Class Form1 Sub fillcombo()
strsql = "select * from device"
Dim cmd As New OleDb.OleDbCommand
cmd.CommandText = strsql
cmd.Connection = con
[Code] .....

For this code I am able to populate the first combobox and when I select the specific item in combobox then the second combobox shows only the first element of that item.

In MS access 2007 I have created 2 tables:
1) Contains the device ex:computer
2) Contains the device and its parts ex: cpu, monitor so here the device has duplicate values
Table names are device and parts.

Setting Selected Item Of ComboBox On Form?

Mar 31, 2009

I have a combobox on a form which has data bound items, the datasource is a dataset called ShiftType that was created using the new data source wizard. The data consists of three columns ID, Name ,Description. Name is the display Member and ID is the value member. This form is called from a different form, a variable containing the shifttypeid is passed as a parameter. I am able to get this parameter across fine.

What I would like to be able to do is, match this parameter with the data in the dataset and find the row index and set that item as the selected item of the combo box. I am confused as to how to proceed with it. Also, I would like to add an extra item to the dataset apart from the items obtained from the database. This represents "NONE", i.e. so if the user doesn't want to choose a shift type they can use the None item. How do i add this without having to add a dummy value in the database.
