VS 2008 - Cases - Detect What Is In The String And So Something For Each Different Result
Nov 3, 2009
Im trying to to detect what is in the string and so something for each different result but im not sure howto, here was my first idea but it obviously doesnt work as you cant use contains that way:
Select Case omg.Contains
Case "1"
MsgBox("1")
Case "2"
MsgBox("2")
End Select

Dim count As Integer
Dim word() As String
For count = 0 To DataGridView1.Rows.Count - 2

I am working with cases, I'm only learning it so far, but just can't get a drop down menu to work that would change the background of a Textbox.
Private Sub cbColours_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbColours.SelectedIndexChanged
Select Case colours
Case Is = "Red"
txtSpace.BackColor = Color.Red
[Code] .....
It isn't doing anything at all...
In the dropdown menu, it has
Red, Blue and Green one per line
When the value (e.g. Green) is clicked, it will then change the Textbox to the colour selected.

I have the following value 48.81, it comes as a string from the database, I need to convert it to decimal, I'm using:
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture)
I'm receiving 4881D and I need 48,81
I thought CultureInfo.InvariantCulture was going to help me with that
EDIT:The coordinate value is 675900.244.I'm "spliting" it like this:
Dim Degress As Integer = Coordinate.Substring(0, 2),
Dim Minutes As Integer = Coordinate.Substring(2, 2),
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture),
[code]....
This is the value of the coordinate in the database?

So i would like to minimise them but how not sure. one point was using classes somewhat minimised but still they are more... like task, cat, sec and type:

I was so happy when I discovered IsLittleEndian field in BitConverter. I thought of course it should be there and I should be able to specify whatever endian I like. Well, my happiness didn't last long. Spent some time till found out that there is no way to set the field.The field is readonly, and it is only set to true in static constructor:
[Code]...
My question is: how come there is very useful piece of code that is already implemented and sitting there in the FCL, but there is no way to use it (unless you start messing with reflection of course)? Is it just because some developers didn't meet the deadline and left the job half-done? Even if so, why the code is not available, but the field is?I hope there is a good reason for this.
I want to make myself clear. I don't need a solution on how to handle big-endian values. I do have a solution. The solution is actually shown in my question.

This LINQ to SQL query From g In Db.Context.Current.Groups Select g.GroupID
generates this SQL:
SELECT [t0].[GroupID] FROM [dbo].[Groups] AS [t0]But this query From g In Db.Context.Current.Groups
Select g.GroupID, g.MemberCount
[Code]...
I very much want to select only the fields I need. How can I persuade LINQ to SQL not to select all columns?

I can't remember very well the instances where my selected items has disappeared as if I did a "Reset ToolBox", the last time I remember was when I installed the Service Pack early this year. But last year I think it has been reset frequently and I find it bothersome to reselect all those items again and again.Is there any configuration that I could set so that my selected items are safeguarded, that is they won't be removed no matter what?

so in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.
For example, I'd take in a line of the series of lines: hello:world@yay
I'd want to break it into three separate strings of "hello", "world", and "yay".
How would I do such a thing in VB.NET?

I am having trouble figuring out what I need to do in order to get the program to drop into the different cases. I am suppose to be doing a case block for this assignment. I believe everything else is good but it always outputs the first case and doesn't progress down depending on the inputs. I tried to number them case 1, case 2, etc.. Here is the code

I am trying to detect if a string's encoding if different than cp1251
- usually its koi8-r and if so convert it to cp1251
As I understood it can be done using encoder and unencode?
I tried searching on the subject, and find almost nothing. I am kinda lost.
