Create A StringCollection Setting And Manually Enter Some Data?
Jan 16, 2008
I have used My.Settings for quite some time now, in both VS2005 and now in 2008, but never noticed this behaviour yet... I must be forgetting something trivial? I create a StringCollection setting and manually enter some data (strings).I write some code to handle this, and I get it to work.
Then, I manually add some new strings (and edit the older ones) in the Settings page, save the project, and run my code again.For some reason, the last changes have not been saved... Whenever I look in the settings page, I see them there, but my code cannot recognize them..

The situation: I have a datagridview with one column (col1). In the datagrid definition (design view), i have created this row, and set the formatting to C2 (or C0, or C - I tried them all). then, I load my datagrid view pro programmatically :
dbl_myValue as double
dbl_myValue = 6.99
datagridview1.item(0,0) =
dbl_myValue
The datagridView shows the data correctly : 6.99$. When I "spy" on the datagridview.item(0,0), the "Value" property is a Double.
the problem: It don't work if the user manually enter a value : click in the cell, enter a numeric value (let's say 100, without decimal to avoid complexity) and then LEAVE the cell (so no more in EDIT mode). The formating just don't applies. When I "spy" on the datagridview.item(0,0), the "value" property is a STRING. So I guess this is the problem, but how can i do?

We have an ItemCommand that makes a DataGridItem invisible. This is breaking the alternating color scheme that we have applied. Is there a way to re-apply the style without rebinding or manually setting each DataGridItem's BackColor property?

I am trying to create a macro to enter data in a label printing application for hundreds of labels- I use an external third party software that's not very user friendly. It has several fields that accept text. The problem is, manually entering the data and clicking "print" each time is very time consuming. Can anyone suggest a way to put a line of text in the field, printing, and repeating the process?

Basically, I'm working on a VB project, one instance of it at home using VB Studio and one at school with SharpDevelop (portable). However, some of the school computers do not have .NET 4 and therefore I can't run SharpDevelop to make the forms, etc. I would like to know how to edit/make a form via code, in Notepad++. An example of this would be setting up a form with controls such as TextBox, Button and perhaps MenuStrip.

I'm new to the world of VB.Net <-> Databases.I'm currently working on an application with SQL Compact 3.5.I realize that data et values on objects from the database but what I want is more custom...Students should have 3 fields for example, tableId, their name and birthYear.1 | John | 20002 | Peter | 1999And so on. What I want is to display their birthday on some label.text = "(" & DBvalue & ")" based on the selection of a listbox (which has tableId's listed as values). You don't have to worry about the update method of that label.text value, I just want a way to retrieve the birthYear value and put it into my label.text together with those extra characters, based on the tableId selected. (which I already have a way to get, so don't worry about that either).

I have a class called CookieMonster, its objective is to simply create a cookie based on 3 parameters passed to it. The cookie name, the cookie name-value pairs and the cookie expiry date.I have experimented with List(of T) and Array and StringCollection, but I'm unsure which is the best for passing the name-value pairs and providing that information to the class.Ideally, I'd like to be able to do something like this:
Dim l As New List(Of String)
l.Add("name", "value")
l.Add("name", "value")

Normally, I'd choose List<String> [or, in VB, List(Of String)] over StringCollection whenever possible: see also Best string container.
However, as it seems, generics — and hence, List<String> — are apparently not supported in VS 2008's settings designer. Therefore, if I want to use a list of strings in my user settings, I have to resort to using a StringCollection there.
Now as I don't want to see StringCollection throughout my code, I need to convert it to List<String>. How do I do this efficiently? Or, even better, am I mistaken and there is a way to use List<String> in settings designer?

I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.
I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....
I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.
Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.
I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.
