View 1 RepliesDetermining The Index Of A List Based On Another List And Vice Versa?
Jan 6, 2012Suppose you have list 1 (ilist1) and list 2 (ilist2) both lists have 3 items.
At index 0 item1 which has text "-- Select --"
At index 1 item2 which has text "Yes"
At index 2 item3 which has text "No"
Both lists have identical items. I would like to know if it is possible to have the selection of list one be "Yes" and the selection of list two be "No" and vice versa using SelectedIndexChanged or something of the sort.
For example:
ilist1 = --Select--
ilist2 = --Select--

A List Where An Index Has Three Values Associated With It?
Nov 16, 2011I have been searching everywhere but I am unable to find a reference to what I need.I have a huge number of entries where each entry is composed of three long numbers:
a b c
1 2 40
2 1 40
1 8 12
3 9 13
8 1 12
ect.
in my algorithm I will find that I need to disregard values in column a which will then lead me to disregard values in column b. I initially thought that I may want to use three arrays and just change the disregarded value to a null value with each iteration. find function that would allow me to not have to loop through the entire array every time.This lead me to want to define the columns as lists where I could remove specific values from the list and reduce the size of the list with each iteration of the algorithm. The problem then is how do I say, listb.remove(8) and at the same time have the corresponding values for lista(1) and listc(12) removed?

View 2 RepliesTreeview Control That Works Similar To Apples Finder Control In Column View?
Feb 1, 2012I have a requirement for a new application development where I must present some information to the user for selection via drag and drop. VB offers the TreeView control which would work nice, however the user does not like the Treeview control's presentation. The user wants a control that work similar to the Mac's Finder control while in column view.
Apple's Mac Finder Control works similar to window's treeview. Finder has a nifty view capability that my users would like in some new development that is being done. The finder supports a "column" view. Similar to the treeview, it starts out in a root list. The difference being, when a user makes a selection and clicks on a node, the node doesn't expand, the sub nodes appear on the pane to the right of the list. Clicking on a sub node, will cause the pane to split again and the items within that sub node appear
to the right again.
This will happen again and again with the left pane getting narrower as the user drives deeper into the sub nodes. That is what I am trying to replicate. Obviously, once the user reaches the base list of items, we have to support drag and drop capability. Does anyone know of a control for VB.NET that work similar to the Mac's Finder control?

View 5 RepliesHow To Search List By Index Or String
Aug 29, 2011How on specific behaviour can be created in a custom class. I want to be able to create a custom class (a kind of list) where I can access the items by their index (this is the easy part), but also by a string that would describe them. Here is an example:
MyClass(1).SomeProperty = "NewValue"
MyClass("Item1").SomeProperty = "NewValue"
You can see this kind of behaviour in dataset for example where you can select a table by its name or by its index like this :
DataSet.Tables("MyTable").Rows...
DataSet.Tables(1).Rows...
How can I create a custom class that will behave like this?

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.
