VS 2010 - Use StringCollections Instead Of String Arrays For My.Settings
Jul 29, 2011
To use StringCollections instead of String Arrays for My.Settings. I've opened a file and have this:
CODE:
But I error on line 2, saying "Object Reference not set in Instance of an Object". So then, I try to use New before I go Into the loop: My.Settings.Trunk = New System.Collections.Specialized.StringCollection
But then i get "index outside bounds of array" still on line 2. This is weird to me. Is it because my StringCollection doesn't have an array size? If so how do i declare an array size for this? Or is this just so totally different from String Arrays?

I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.

Is there a way to compare two variables that are StringCollections to find out if they both contain the same data or not?

I have two different 2-dimensional arrays. I assume the setting i need to save them to is a string setting, as is the cast with regular integer arrays. The first 2-d array I need to save is an integer, the second a decimal.
Let's say the settings are called my.settings.2darray1 and my.settings.2darray2
Let's also say the arrays are:
vb
dim 2darray1(50, 99) as integer dim 2darray2(50, 99) as decimal
What would the code be to load each array and save each array?

I'm still doing upgrades on my program that i'm creating and i've run into a bump again. I'm currently using a multi-dimension array to store a name, email, password, email provider, and user name. These 5 values are stored, corresponding with the latter, meaning the array is build as: name 1....n user name 1....n user email 1....n user email provider 1....n password 1....n So my question is, how can i store this in My.Settings? To be clearer, i'll use code: My.Settings.Name = name My.Settings.UserName = userName etc..... My current set up for a first run is like so... My.Settings.Password = adminInfo(2, 0) My.Settings.UserName = admingInfo(1, 0) etc.

1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...
2. I'm not actually saving them when I think I am.
Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?

I am developping an app which talks across a network and will eventually be used to read in a text file (on the client) and transfer it to the server. Currently, the server and client succesfully connect to each other using the Tcplistener/Tcpclient classes. I am now trying to send some data across the network using the networkstream class, which I have implemented.Currently for testing purposes i am sending a char array which contains the characters "hello" which succesfully sends and outputs to console on the server. Although, "hello" is followed by a long list of whitespaces. I have tried converting this to a string array on the server and/or client and using the string.Trim() function (amongst trying many other things over the past couple of hours) although the output remains the same.

I'm trying to make a function in VB.net that will loop through an algorithm. I've split the algorithm into an array using the Split command, so I have an array with the values. I then try to loop through them and replace a # with "Number" where necessary, however VB.net throws an error. Algorithms are in the format A B C D E F 1 2 3 #
Function generate(ByVal alg As String)
Dim algSplit As String() = alg.Split(" ")
For Each digit In algSplit

I have a string array Array1 and a string array A2. I want to combine these in a 3rd array A3 but excluding duplicate values. Can this be done through lambda expressions or only through iterating through the array and checking array.Contains()?

I have a string array of size 51 CardListIn() representing randomly ordered cards in a deck {1d, 2d, ...14c} e.g. 9d = 9 of diamonds and so on. I then have 52 text boxes for user input. These have been put into an array of text boxes as so:[code...]
I want to search my original string array for any cards the user may input in any of the textboxes and then delete those entries from the string array.So say the user enters "1d" in one of the textboxes, I then want that removed from the string array.
I'm parsing through both the array and the text boxes fine, but for some reason that I cannot fathom, it doesn't find a match. The string array definitely contains "1d" and the textbox definitely contains "1d", but it doesn't register as a match. I've tried using Val() for the string array and the text boxes, but then it removes every entry beginning with a 1, e.g. "1d", "1h", "1c" & "1s".

I'm going to describe what I'm trying to do and then what I'm doing in hopes of making this as clear as possible.I'm trying to create a way of having data avaialble to the application that could be changed in the future and not have to recompile the code.Normally I do this for my connection strings incase something changes, this way I can just change the file and I'm good.however in this case I'm trying to store a long string variable that contains something like(including all " in the string) "Dear " + emailRecp + vbCrLf + "Thank you for buying our product...."
Now when I do this as part of the code with something like strMessage = "Dear " + emailRecp + vbCrLf + "Thank you for buying our product...."when I look at the output from this it looks like (which is what I want):
Dear Mr Smith
Thank you for buying our product....
however when I do strMessage = My.Settings.purchaseMessage (even with .ToString()) the output looks like Dear " + emailRecp + vbCrLf "Thank you for buying our product....how to do this in another manner that won't affect performance.I have also tried to trim the " from the first and last char positions and no luck.

I'm trying to give my users the option to move their database to a different location, currently the datasource is set as an (Application Connection String) in the Project Settings, I know that when the scope is set to "Application" it cannot be modified but I'd like to know if there's a way for me to edit the location through code of my database in the application settings without crashing the program, can this be done? The purpose is to give whoever uses my application the freedom to choose where the database should be.

does your IDE ever get amnesia?in the line before it is clearly defined.in the following line it is not.Maybe it's a faulty translation from Tangible Software.the C example i'm looking at:
IAnimatedMeshSceneNode* newNode = (IAnimatedMeshSceneNode*) oldNode->clone();
translated as:
Dim newNode As IAnimatedMeshSceneNode = CType(oldNode.clone(), IAnimatedMeshSceneNode)
had to make a dummy for it because i can't use arrays with CType.

I'm trying to create a favorite box in my web browser using this code in Favorites.vb
Public Class favorites
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
[Code]....
Now I have it so when you click the add button it will put the URL in the string FavList, and place the URL in Listbox1 however I have no idea how to save it, and load it.
So the next time the user opens it, it will have the URL in the string and URL box, so when they click the URL in listbox1 it will redirect the WebBrowser. I think it works like that already I just need to know how to save it, and load it.

HumanName (the variable, not the setting) in this code is a 1-Dimensional string array. HumanLevel is a 1-dimensional integer array. There is no error in this code, but for some reason despite the fact that the integer array actually saves to settings exactly as it is supposed to, the string array causes the program to crash.

This is regarding a windows app in Visual Studio 2005, a VB Windows application.'ve stored a connection string called strSQLConn in My.Settings. I'm trying to change the Server in code. I set a string variable called strConn to a new Connection string. My.Settings.Profile2006sql = strConn
This produces an error saying that My.Settings is readonly. I'm missing something basic here.
I don't know if this is the best way to change a connection string to toggle between a development server and a production server. My understanding is that if the setting Connection string is changed it will be used as the default for all the table adapters in a strongly typed dataset. Is that the case?
