Variable Lists In Dictionary (String / Boolean And Integers)
May 5, 2011
So I had a smart idea to make a dictionary with all my variables so I could save them easily in chunks. This includes String, Boolean and Integers. When I was in Framework 3.5 I only had a few warnings about stuff that I didn't have coded in, but now in Framework 4 I am maxing out all my warnings with Implicit conversions. Personally I don't want to go to every number and put quotes around it put quotes around "True" because then it may change the method.
Public Function loadGeneral(ByVal fName As String) As Boolean
Dim tempDict As New Dictionary(Of String, String)
For Each kvp As KeyValuePair(Of String, String) In GeneralSettings
Dim v1 As String = kvp.Key
Dim v2 As String = QuizZing.My.Settings.GetSetting(fName, v1)
[Code] .....

If I try to put a string into a Boolean variable such as this:
Dim testValue As String = "True"
Dim bool1 As Boolean = testValue
With Option Strict On I get an error and the suggested fix is to change the second line to:
Dim bool1 As Boolean = CBool(testValue)
This is fine, But - what are the advantages / disadvantages of doing this instead:
Dim bool1 As Boolean = Boolean.Parse(testValue)

I am trying to up a private sub routing based on the Text Changed Event for a listbox, inside of the event, I want to set a boolean variable to true. I have it set up, but for some reason it is not getting called.
Basically what I am doing is the user is being prompted to enter data in an input box. I am taking the data that is entered on the input box and populating it in a list box. I want to know if the text in the listbox has been changed, hence changing the blnIsChanged = True
Can I use text changed with a listbox???

Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]

In other words the values of the last row used are stored in every key, value dictionary combination. How do you prevent this from happening? It is clearly associated with the use of the temp variable, as the dictionary changed as the temp variable changes. Is there a way to only copy the values from the array rather then associate the dictionary with the changing values of the array?

I have a struct setup like the following[code]...
I then loop through a counter and add each PersonInfo object to the Dictionary. The Primary defaults to false if the Code is already in the Dictionary, but if it has not been inserted into the Dictionary, I want to set the Primary to True. It would be easy to check if the Code was the key, but I can't because the Code is not unique.

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.

My program uses the serial port to receive characters as a string, then it should extract the integers from this string. This seems fairly simple, but so far has been a very tedious job.
My string is called txt. The problem is that there's no telling how many characters / integers txt will hold at any given moment. For instance, it may equal "4" or "4 5 6 7" or "P 0 1 2 3 4 5 6...255" - with spaces included. I need to reference every number within this string to use as data. I've tried the following:
dim c as new char
dim n as new integer
dim i = 1

I have a following value "1pm 2am" that I'm using a regular expression againts in SSIS to extract hours from in order to store separately. I've tried using both of the regular expressions below but both only yield the first number "1".
"(d+)"
"(*?d{1,2}*?)"

This should be fairly easy, yet I have no idea on how to approach this. Perhaps the split command . Anyway, what I need to do is split as string into two integers.
For example MyStringXS = "10, 20"
I need to end up with:
MyIntegerX = 10
MyIntegerY = 20
BUT!
These strings obviously change. So it could be MyStringXS = "120, 230" Or MyStringXS = "12340, 20342" And so on.

Dim numbers(9) As Integer
For i As Integer = 0 To numbers.Length - 1
numbersString &= numbers(i).ToString & " "
Next

I'll try to clarify by using the following example. In here I have two Drop down lists (ddlInsertEmployee + ddlInsertCustomer) which should both be bound to fetch data from tables [Employee.EmployeeID] and [Customer.CustomerID] and insert it into table [Task].
The problem is that it inserts data from Employee.Fullname and Customer.Fullname into resp.Employee.EmployeeID and Customer. CustomerID.If I would change the Drop down lists to textboxes, and manually insert the IDs, it works like a charm, but this is not very efficient, I want to be able to see the entire Fullname.how to change my Sqlstring in order to make this work correctly.

I have a bunch of 10 digit integers that I'm passing in a URL. Something like: "4294965286", "2292964213". They will always be positive and always be 10 digits. I'd like to compress those integers into the smallest possible form that can still be used in in a URL (aka letters and numbers are perfectly fine) and then uncompress them later. I've looked at using gzipstream but it creates larger strings, not shorter.

I've got a routine that checks a website my my external address. What I'd like to do is loop through the string just to get the first 15 numbers and full stops (periods). But that isn't my question, my problem is I've got this routine that isn't building because of a string conversion issue. I don't know how to correct it.

I encountered due to a coding error a behaviour I can't explain.In one line I have an implcit conversion from a string to a boolean value:
Class myClass
Public Property myString() as Boolean
Return "123" '<= Implicit Conversion occurs here
End Property
End class
[Code]...
Are there any differences in the behaviour between the .NET Versions?The code is compiled against .NET 2.0 with implicit conversion on.

I fill a DataGridView with the result of a database query. I have a boolean field named Gender. I want to show "Masc"if it value is True or "Fem" if it's False.
I can't assign a string value to a bool type cell. How can I do this?
PS: I've seen a C# example, but I can't understand how to do this in VB.

From what I read it is a good convention to name a method that returns a boolean value with the prefix of "is" or "has". So in keeping with this convention I am trying to name a method in my program with this prefix but I am running Specifically I have a class called Day. It is a simple class with a few data members and one method that returns a boolean value of true or false. The name of the boolean variable is isSpecialDay. This class has a method called isSpecialDay which takes the date of the day, applies some criteria to the date and then sets the variable isSpecialDay to true or false. My problem is that the boolean variable is named isSpecialDay and so it the method. What should I do?
Public Class Day
Private TheDate as String
Private DayName as String
