Convert A String Of Key / Value Pairs To HashTable Or Dictionary Or?
Jun 19, 2010In VB.NET, how can I convert the following string into some kind of key/value type such as a Hashtable, Dictionary, etc?"Name=Fred;Birthday=19-June-1906;ID=12345".I want to extract Birthday or ID without having to split the string into an array.I'd prefer not to split the string into an array in case the format of the string changes later.I don't have control over the string.What if someone switches the order around or adds another element?
View 6 RepliesVS 2010 Creating A Game Of Pairs As A Project
Apr 26, 2012I'm having a little trouble creating a game of pairs as a project.Basically I've got to the point where I can start a game, layout a bunch of cards in a grid, 6x6, and then have a way of matching the pairs together. First of all I used a For loop to assign the cards into a two dimensional array. They are pictureboxes however so when a user clicks on 2 cards, checking them to see if they match has become confusing. I've tried to stuff like this for example but it's not working: [code] This doesn't work because it can't compare the picture boxes stored to the array slot. Is there any clever person with a way around this? Or that can think of a way to compare them. The pictureboxes kinda need to stay like there though :/

C# - ASP.NET TextBox - Initialize Text Attribute Within Line Code <% %>?
Jul 26, 2011I need to initialize the text attribute of the text box element with a property from some where else when actually I can simply do this from code but it will be much more convenient if it possible to do it like this:
<asp:TextBox runat="server" Text="<%= new ContextItem("title").Value %>" />
Unfortunately the above can't be done.. how to make it cleaner then to write it again and again in the code behind?

View 4 RepliesUse Linq ToDictionary To Return A Dictionary With Multiple Values In The Dictionary Items?
Jan 25, 2010I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

Flatten A Dictionary Of Dictionaries And Sum The Values Of The Inner Dictionary With LINQ?
Apr 16, 2012I have the following object:
countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))
The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:
groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)
The best result I could get was:
Lookup(of MasterCategory, Dictionary(of Date, Integer))
From:
countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)
Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.
Current Code
[Category Class]
- MasterCategory As Enum
- Name As String etc

VS 2010 First Shot At A Dictionary
Jan 21, 2012I am a relatively new coder and have been learning quite a bit over the past year. I have a fully functional application that works fantastic, and I am now in the process of learning better coding habits.The original code is set up like this...I have a combobox where I place the collection items in manually.On the selectedIndexChanged event handler I used a case statement that looks something like this: [code]Ok, so as you can probably tell, the file name and the dropdown option have the same name, and when it's selected it loads the contents of the resource file into the listbox. It works great...but I was told that since the case statement is ever growing, I should use a dictionary instead. So my goal was to simplify my coding efforts (when I add a new item I have to code in three different areas...with the dictionary, I only have to add the new item and everything else will take care of itself).
So I created the dictionary in a sub, an used a for each loop to dynamically load the combobox with the key values.My values in the dictionary are set up as "My.Resources.filename" where filename matches the key value.I want to be able to call the value based on the selected key. After 5 days of researching I think the best option is the TryGetValue method, but I cannot get it to work...I have used so many different examples, that I actually had to get rid of them all and don't have any current code to post.
1) If I redeclare the dictionary, won't it be empty?
2) How do I "extract the value based on the selected key an set it to a variable (i.e. myvariable = My.Resources.selectedkeysvalue)

Use SortedDictionary To Store 65,000 Keyvalue Pairs?
May 17, 2012I'm thinking to use the SortedDictionary to store 65,000 set of keypairs and from time to time during my program execution, I need to retrieve the value from the this dictionary. May i know will there any concern especially in term of speed of execution if i use this method as above? Is there max. capacity that a dictionary can hold?
Previously, i was thinking to use a simple 2D array to do this, but it mights slow things down because in order to retrieve the value, i might need to loop through the whole array till i found the value that i want.
