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 RepliesI need use a collection of differents types, this is:id (long), name (string), type (integer), open (byte) idReg (integer)I would like use it like an array but using the "field" id as key. The only way that i found for do it possible is using a custom class and then a dictionary.This is the custom class:
Public Class frmColeccion
Private m_name As String
Private m_type As Integer
[code]....
What I would like to do is be able to take a Dictionary of key value pairs and make the key the name of a variable and the value the value. From searching the net seems to be very vague on whether this is possible.

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

String,
ByVal VendorId

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 wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.
View 6 RepliesI 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:

View 7 RepliesI have to make a program that reads a txt file after reading it, show it in a richtext box and in another tab make the average of the grades the input received sort it by the student id and then in the same rtb sort it by the average of their grades, and finally save it on a new text file.
The text file input is something like this
12 3 10.0 6.9 7.3
19 2 6.7 9.3
10 3 4.5 9.3 4.5
[Code]...
As you noticed in the input the first number is the student ID, the second number is the number of tests made by the student, and the other 3 numbers are grades, in the output the first number is the student ID, the second number is the average of the tests, and the other 3 numbers are grades, I don't have a problem opening and saving a text file and neither creating a tab with 2 RTB , my problem is how do I tokenize or read the input line by line, i guess that i need to use the split function but I don't know how to implement it into the program.
I have some functions in my VB.NET DLL which I can 'hide' from my VB6 app by using the following: <Runtime.InteropServices.ComVisible(False)> But is there a way to make a function ONLY visible to COM clients and not to .NET assemblies? This way I can use Shared methods for the .NET side avoiding the need for an instance declaration.

View 3 RepliesI have a VB.Net exe application that has a function in it that contains my encryption method that is used through out my application. This function is used to generate all my encrypted passwords and files etc. therefore for obvious reasons I do not want this to be visible to end users. In my application this is fine as it is compiled as a .exe. However I want to now create a ASP.Net web based version of my application.
Now here comes the question, if I was to create a web version of my application then this function would be visible to the end users along with a large number of other functions that if edited could bypass security and license control.I would like to know what is the best way to keep my ASP.Net webbased version secure from tampering, or is ASP.Net not the best for this?
