SelectedIndex : Gets Or Sets The Zero-based Index Of The Currently Selected Item In A ListBox?
Jun 7, 2012First 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:
Dim I As Short [code]..........
Get Listbox Text Using Index Of Its Item?
Aug 19, 2010In simple terms, I want to compare the value of a databound listbox display member with another string. However; I need to convert the listbox databound items to an array first as I may have to do 1,000's of comparisons on this.
I have a databound listbox from a sql server table that populates fine. I'm trying to retrieve the display value of a listbox item without selecting the item. My goal is to compare items in listbox1 with items in listbox2 and if item is in listbox1 matches an item I want to load into Listbox2, then I do not add the item to Listbox2. Listbox 2 is not databound but contents I'm loading come from a datatable.
So, I iterate through the items in listbox2's datatable but as I'm adding the items from the datatable to the listbox2, I check if the item exists in listbox1. The data that is being compared is the Displaymember of Listbox1 and a string value I want to manually load into listbox2.[code]....

VS 2008 Retrieve The Selected Items In A Listbox - Save Them To A Collection
Jan 6, 2010I want to retrieve the selected items in a listbox, save them to a collection, and then use that collection later. I thought that was simple enough, but when I clear the selected items in the listbox, my collections (items, indices) change. I found this out by stepping through the code.
Basically what I'm wanting to do is move items in the listbox up or down (up in this case), and still keep them selected.

Nov 1, 2011I get this error when clicking on any of the letter buttons in my repeater. The sql statement I have works in sql server, but on my page it just errors out. The only thing that is different is that in sql server I change '@CompanyID' to an actual ID and '{0}' to 'a' so the query will run. All the posts I have found online with this problem say something about this-->{0}, but I don't see anywhere that I might be trying to pass more than one argument or have this wrong.[code]

Dynamically Create Array Based On String Length Property and Index Of Method
May 4, 2009I would like to format output to a property of a custom control I have made.For instance I have a literal control in my control and when populated I want to check if it is longer than 30 characters long, if so, then go to the next space (as to not cut the word off) after the 30th character and place a <br /> tag in to place the next 30 characters on the next line.So if there were 100 characters in a string, there would be 3 line breaks in the label.I have the looping worked out to get the label populated but cannot get how to dymaically create the array based on the string lenth property and index of method.
