View 4 RepliesConvert XML To Program Dictionary?
May 29, 2012I'm trying to put sub-child values from XML into a dictionary collection using LINQ. I've done this with lists and custom collections which follow the same structure as the XML but am unable to search for specific values. If I know parentName, childName, and subChildName I want to be able to find subChildProperty1.value and subChildProperty2.value without iterating through the entire collection and each of the subsequent sub-collections, as I have to do with lists. This may not be the best implementation, and am open to suggestions, but still would like to figure out how to make this work.[code]...

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 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

Wpf - Convert C# ObservableCollection Sample To Dataset Or Equivalent
Feb 23, 2011I have a C# example that is populating a multiselect combobox. This was from an example found online. It works fine with the static values coming from the observable collection. I want to change this to be database driven from a SQL Server backend, but was having issues. I did get it to populate the combobox, but the selection is acting kind of screwy. Some type of simple query from a Northwind table would suffice such as: "Select CategoryName from Categories".

View 2 RepliesIDE :: Dataset Code Behind Datatable.ColumnChanging Event Firing / But Dataset.HasChanges Property Not True
Jan 28, 2010I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
