VB Listbox Cannot Be Indexed Because It Has No Default Value?
Mar 17, 2010I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this:
While tempInt > Listbox.items.count then
if searchString.contains(listbox(tempInt)) then
end if
tempInt+=1
end while
Everything in the loop is fine but VB gives an error on the listbox(tempInt) part. The error is "class windows.forms.listbox cannot be indexed because it has no default value". get around the default value crap? I tried putting in a blank string but no change.

.net List(of T) Not Returning Indexed Object?
Sep 30, 2011I'm working on a small game that is based on a map of grid squares.I have a class (clsGrid) that stores a few properties for each grid square.The grid square objects are organized into a list(of clsGrid).A loop and stream reader are successfully reading properties from a text file, putting the properties into grid objects, and adding the grid objects to a my list of grids. When retrieving a grid from the list of grids, I'm getting unusual results. Regardless of the index I give the list, I always seem to get the last indexed grid in the list.The debugger seems to suggest that the right numbers are being read into the stream reader and they are being added to gridHolder. However, the message box at the end will always show me the LAST grid.id, regardless of the index I give it.

Jul 6, 2009I have a form with a lot of PictureBoxes. I created an array of these by name, but when I index the array I cant assign an image to the indexed item. In fact all the indexes appear to be nothing. Is there a way to create an array of controls and access them from the array?

View 3 RepliesCreating Dictionary Indexed By Strings
Oct 24, 2009I'd like to create a Dictionary that is indexed by Strings: Dictionary(of String, ...). I'd like the Type after the comma to be an Array of MyObject's. If all I do is the following:
Dim D as new Dictionary(of String, Array)
I feel like I'm missing out on some performance very time I access a member:
Dim Object1 as MyObject = MyDictionary("Key1")(4)
Doesn't it have to perform some type of lookup to figure out what type of object the array is holding every time I access it in this manner?
List Of Integers Indexed By Key Or Index?
Jul 25, 2010I would like to create a list of integers. The list will be items that I need to index by a key (string) or an index, which I set. For example I have items 1, 2, and 5. I would like to call Array(5) = 1. Where the the 5 is indexing a particular item 5, not the 5th item in the array. Using Array("5") = 1 could work as well. I tried using a List, but the only index is the ordered element of the list. I tried a Collection, but I kept getting errors that the items of the Collection are read only. How can I do this?
To be more specific, I have a simple game application which has a Player class. Each Player is trying to collect hits of say 3 fields {1,2,5}. I need to store how many times a player hits each of the 3 fields. So, I would like to read and write using logic like player(1).field(5) = 5. I want to add an object to the Player class which stores the number of times each of the 3 fields has been hit.

VS 2008 Intellisense, Indexed Properties?
Sep 26, 2010I've wondered this for a while, when I hover over an object's properties when the program is paused (from a breakpoint) I can see the values of each property but when it comes to a collection it wont list the objects in the collection unless I specify an index, how do I specify an index?Basically I have a form with a ToolStrip that has 12 items in it, I would like to see what the 12th item is but can't because it's an indexed property.
