Alright im trying to make a mini word but instead its going to correct the spelling when its save to a text file.How would i make my program check all the words in the textbox fix them then save it.
Ps: Would i have to make a dictionary and import the text file to the application or is there even an easyer way to do this what source code rather than reading the dictionary text file and comparing it.
I 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.
[Code]...
I have created a class with a function in it. I have a collection of data I want to pass back. I tried an arraylist first. Now I am trying to use a dictionary. My problem is that it creates the dictionary ok, but I am only get the last row of data from my
Function GetWeldAuditInfo(ByVal ResourceId
As
String,
ByVal VendorId
[CODE].........................
I 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

I have created a Dictionary class (MyDictionary for the example). I am currently trying to pass MyDictionary into a function, filter it into a new instance of MyDictionary and pass this new instance into another method. When I am attempting to create the second instance from the filtered first instance of MyDictionary via Lambda Expressions and the ToDictionary Method, I am getting the following error:
Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.Int32,System.String]' to type 'MyDictionary'. I have simplified the example and recreated it in LINQPad and am getting the same error.
Here's the simplified version of my code:

I use VS2005 and I have just started working with the dictionary in particular the Dictionary.ContainsKey method. At the bottom of the page in the msdn library it says the following in the community content How to make sure that Contains functions properly.
View 3 RepliesI have a series of "keys" and associated "descriptors". I have them set up in a VB dictionary to use the keys to select the descriptor for output (the descriptor is the English translation of the hexadecimal key; both are dictionaried as strings).I have looked at the help files and all they do is "for each" statements to retrieve the entire key list or the entire descriptor list. What I need to be able to do is take a key, determined early in the program, and use the dictionary to look up what the English equivalent is. I don't need to retrieve ALL the keys or ALL the descriptors.VB6 made this easy.I'm having trouble doing the same thing in VB 2008.I can provide a sample of the code I have been working with after I get access to that computer.

I have 2 different files containing data in a CSV in following format:
CSV1
HTML
ID:,Descp
498 ,1010
[Code....
I am wondering if it is recommended to use Vb.Net Dictionary to load these files and compare and report only the entries that mismatch into datagrid..
note the entries in CSV2 - 625 & 778 are different from CSV1 and are to be loaded to the datagrid..
I wrote the following function to randomize a dictionary object:
Friend Function RandomizeDictionary(Of T)(ByVal oCollection As Dictionary(Of String, T)) As Dictionary(Of String, T)
Try
Dim oResult As Dictionary(Of String, T) = Nothing
[code]....
This code works fine on simple dictionary objects, but when I use it with complex types I get a type cast exception. For example, I have an object X that Inherits Dictionary (Of String, Class Y). If I call the randomize function on object X, I get the type cast exception. I don't really understand why it cares what the type of the dictionary value is, I thought that was the point of using generics.
In summary the following all work:
Dim x as New Dictionary (Of String, String)
Dim x as New Dictionary (Of String, Boolean)
Dim x as New Dictionary (Of String, Integer)
This does not:
Dim x as New Class X
Class X Inherits Dictionary (Of String, Class Y)
I'd like to use a dictionary to store the contents of an ini file. Now I know you can simply say
myArray.add("key1","value1")
myArray.add("key2","value2")
etc...
But Id like to store more information with a specific key, not just a single value, so id like to associate other values with key1 eg firstname,surname,address.
So by knowing the value of 'key1' I could retrieve the firstname, surname or address associated with it.
I know in PERL, hash arrays work in this manner
eg
$hash{'key1}{'firstname'} = 'john';
$hash{'key1}{'surname'} = 'smith';
etc....
I need small code for array/dictionary to pullout data conditionally.i have data:
oid----opriority----task
10--------3-------Task1
5--------1--------Task2
1--------6--------Task3
i need to build one array/dictionary to store the data in this format then i can pull the value like.
select oid where task = task1 order by opriority
It is easy for me do in database table, This is run time and i need to work in RAM. how i can build the array and pull the data accordingly.
Ok I have a project which has a MDI parent. Inside the parent I have multiple isntances of a form load(frmLine1t5). When my program loads it will load a different form(frmSelect) and if I manually load a different form(frmRetests) I can put frmSelect on top of frmRetests and bring one another to the front if it's clicked on(without using the bringtofront method)However as soon as I load a single instance of frmLine1t5 I immediately can no longer bring ANY form loaded into the MDI parent(before or after frmLine1t5 has loaded) to the front. I can only bring them to print IF I use .bringtofront method

View 3 RepliesI have a dictionary of key=string and value=datatable. I use a key to retrieve a datatable and assign that datatable to a new variable. Then I make some updates to the variable. However, I find that the dictionary itself is being updated even though I'm only updating the variable. This causes significant issues when I try to reference the dictionary later. How can I set up my dictionary so that it won't update when I use a value?
dim dt1 as datatable
dt1=dictionary(key)
For row=0 to dt1.rows.count
dt1.Rows(row)(4)=dt1.rows(row)(4)/2
Next row
'at this point, when I look up dictionary(key), the value I get shows all of the original values divided by 2.
It is possible to output all the dictionary values to a textbox? Not the keys, just the values of all the keys.

[code] For example, if the word was "cat" it would return true. If the word was "jlakfh", then it word return false. To do this i need some kind of dictionary array or something. How do I do this? If it helps, I only needs words with less than 7 letters in them, and more than 2 letters in them. Also, I don't need the definitions of the words. I only need the words themselves in the arary. Do I need to manually input all the words into an array or is there already a dictionary control or something that I could use?
