I want to insert an array of strings using Arial Unicode for an Arabic Dictionary. I already had one with Xp but as soon as I changed my operating system to Vista, the string switched the 1 and last place of the Arabic Letters around. And they are no longer correct spellings?
View 3 RepliesThis Visual Basic program running on Visual Studio 2010 needs modification on the search coding, so a search for words from the dictionary is performed, then the program should test words from dictionary to test if words value equal 100 based off the given rule :
A=1, B=2, C=3 ..... Z=26,
Then displays all the words from the search that equal 100 in a listbox. I will attach the program I have so far. I would like to modify the program so when the search button is clicked, the program will check all words from the dictionary, or English Language, or etc..which equals 100. The goal is to find inputted words by the user that equal exactly 100 and also searches for words in the dictionary that equal exactly 100.
This Visual Basic program allows a user to input a word and also SHOULD search for words in the dictionary, English language, etc. that equals exactly 100 based on the rule, then the program calculates the value of inputted words or searches based on the rule. I need to modify my program so that the search button will search all combinations of characters that equal 100 (and possibly display in a second listbox) and compare to words in the English Dictionary and then display the words from the dictionary that equal 100 in a third listbox (I have not added second or third listbox to original program). Is this possible, and how does the code look and work to perform a search of all words in the Dictionary .

I have a dictionary collection as bleow:
mydic.addvalue(key1, val1)
mydic.addvalue(key2, val1)
mydic.addvalue(key3, val1)
mydic.addvalue(key4, val2)
mydic.addvalue(key5, val2)
From the above dictionary I want to delete all the entries where value == "val1", so that the result would have only following entry:
mydic.addvalue(key4, val2)
mydic.addvalue(key5, val2)
My VB source code is on VS2008 and targeted for 3.5
How can I delete items with forbidden words?

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.

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

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.

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.

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.
View 3 RepliesAlright 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 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....
Created for Bill Smith Bill Smith 100 Maple St. Nowhere, MI 49091 Program Information undecided about Your Career Path? I can find the position where "Created for" occurs in the string
VB
Private Function FindText(ByVal strText As String) As String
Return InStr(strText, "Created for")
End Function
I am trying to get the first and last name that occurs right after the "Created for" in that string but I have not found a good way to do so. Essentially there are multiple files in a directory that I am spinning though and changing the name of the files to match the name in the file.
1. Is it possible to have vb.net piece together a legitimate word of a specified length, or do I need to have a massive word list, and generate a random number to pick a word from this list?
2. I also need to separate each letter of the word and display an image for each letter, and each letter going to the next based on a timer, and can also repeat on a button click.
Eg: TWO would end up displaying T W O, a few seconds apart from each other.
So my latest project focuses on sending txt commands over from my cell phone to my email, which gets read by a program, that carries out the specified command. My latest command i want to implement, is being able to define words, and have it send me a txt back with the definition. Now I know how to send texts, and all of that stuff, but I have found it hard to find anything on defining words. At first, i tried to read websites, and simple redirect a webpage to google definitions, but that led me nowhere.

I am making a program which generates Tambola Tickets. The program reads a list of movie names from a file and it randomly selects x no. of names per ticket and writes those names to a file.
For e.g. imagine there are 24 movie names. The program has to print 10 tickets and each ticket will habe 12 names.
I have written a program which does that but I think my random no. generator is repeating a few movie names pretty frequently.
plus I have to ensure that no one ticket can have a name repeated.
Dim NoTickets as Short = 10, Total as byte = 24 ' total = total movies in array
' Duplicate is function that ensures that no number is repeated
' MovieList is normal array with movie names
