Jun 14, 2010We all know what a Static variable means! Recently I came across a problem that I have no idea about! I even don't know whether I'm wrong somewhere or that is a VS fault. Whatever it is, I can't figure out the cause. Anyway, I simply opened a VB 2008 project and added 2 Windows forms to it: Form1 and Form2. Then I set Form1 as a MdiContainer by setting its IsMdiContainer property to True. Then I added a CommandButton to Form1 and put this following code into that:

Class-level Static Variable Per Instance?
Jan 28, 2010I need a static variable to get a ListItemCollection from a List control (I can do this, but if I don't set it as Shared It's not preserving the values as it should). The thing is that this class is a SharePoint webpart, so I most probably will be using the webpart more than once, and I need this variable to be unique to each webpart, which shared doesn't accomplish.I tried everything you can imagine. I placed a Static variable within a Sub (shared and not shared), I tried it with Properties (also Shared and not shared)...

C# - Access A Shared/static Member Through An Instance Variable?
Mar 3, 2011Here's an example of what I'm talking about...
Public Class Sample1
Public Shared Function MyValue() As Integer
Return 0
End Function
Public Sub Code()
[Code]...
Me.MyValue gives a warning in VB.NET and (the equivalent code gives) an error in C#. Is there a particular reason for this? I find it more intuitive/natural to access the shared function using 'Me.MyValue' - but I avoid it to keep my warnings at 0. Did someone else just decide 'Nah, it makes more sense to do it the other way' or is there some technical reason I don't understand?
EDIT: I was thinking of it wrong, more like a 'sub class' in OOP. Even if something is declared in the base class, you access it through the instance you have. But that relationship is not the same with shared or static.

Jun 30, 2009I need to generate 'real' random numbers from 0 to 500 (e.g. 247.214, 477.125, 1.247, 54.078, 147.001 ......etc). I am using this method:
Dim Myrand As New Random
Dim Res As Double
For i = 1 To 10
Res = Math.Round(Myrand.NextDouble, 3)
Next
This method gives numbers between 0 and 1. if I use: Res = Myrand.Next(0,500), then this gives Integer numbers.
The questions is: Is this possible with (Dim Myrand As New Random) or I have to try another way (e.g. Rnd() ) for doing this?
