Feb 15, 2012I am using this example I found to learn how to load class files and access variables through them. This is in a file called Class1.vb in the App_Code folder (this is not an app project):

How could I access the vartest variable without using a session, since if this is accessed by multiple functions at the same time the variable can be overwritten I assume. Is it possible to go the other way, where a variable is sent to a class file?

VS 2008 - Comparing Variables In Private Sub With Public Class
Nov 11, 2009I have these list of RS-232 strings declared in my public class
Public Class TouchInterface
Dim WatchTVbtnCmd As String = "rs232command1"
Dim VolUpbtnCmd As String = "rs232command2"
Dim VolDownbtnCmd As String = "rs232command3"
Dim SystemOffbtnCmd As String = "rs232command4"
Dim RadiobtnCmd As String = "rs232command5"
Dim MusicbtnCmd As String = "rs232command6"
I then have this private sub. For the sake of this thread, what I would like to do is get the name of the label that was clicked which in the code below is already done, convert it to string (not sure if this needs to be done), this is also done in the code below. Next I want to compare the labelnamestring to all the variables in the public class to find out which one it is equal to and then disply that variable which should be my rs232 string in the message box. I have also added "Cmd" to the variable names above so I also need to work out how to add the text "Cmd" to the string to properly compare.
Private Sub Musicbtn_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WatchTvbtn.Click, VolUpbtn.Click, VolDownbtn.Click, SystemOffbtn.Click, Radiobtn.Click, Musicbtn.Click, GardenVolUpbtn.Click, GardenVolDownbtn.Click, GardenRadiobtn.Click, GardenOffbtn.Click, GardenMusicbtn.Click, GardenMediaCenterbtn.Click
Dim labelname As Label = DirectCast(sender, Label)

View 3 RepliesDeclare Global Value Type Variables With New?
Dec 29, 2009What happens if I do: Dim x As New Int32? Is a object of int placed on the heap? If it is, maybe your application would be able to access global variables faster if they were reference types.
A global variable as an value type should be somewhere at the bottom of the stack most of the time and it might take more time to get to this then to get a object from the heap. Unless it's the same story with the pointer of this object is also at the bottom of the stack of course.

Inside The Service Class, Declare A Class Variable Named Started?
May 8, 2012Create a class named Service. Inside the Service class, declare a class variable named Started. The datatype of this variable is Boolean.Public Class Service Dim started as Boolean End Class Create a class named Server. Inside the Server class, declare a dynamic array that can contain elements of the type Service.(Note: For convenience, both the array and the variable Started can be accessible from a client program that creates an instance of Server and Service respectively)
Create a constructor for the Service class. When the constructor is executed, it will set the value of the class variable Started to True. Create two new classes: WebServer and DatabaseEngine. Both of these classes inherit from the class Service. Inside the Service class, declare a Sub procedure (method) named Terminate. This method should display the following text Service stopping in a message box when executed.This method can be overridden in classes that inherit from Service class.
Inside both the WebServer and DatabaseEngine class, override the method Terminate inherited from their base class Service. Both methods should first call the base class Terminate method. The messages Web server stopping and Database engine stopping should also be displayed in a message box when the Terminate method for the WebServer and DatabaseEngine are called respectively. These messages should only be displayed if the Started variable inherited from their base class is not equal to False.
Inside the Server class, declare a method named Shutdown. This method does not return any value. When executed, it will call the Terminate method for each of the Service instances (if any) in the arrServices
array. You should call the Terminate method within a For Each loop that loops through the elements of the arrServices array.
In the Sub Main method, create an instance of the class Server. Set the size of the arrServices array in
your Server instance to contain 2 elements. Create first a WebServer instance and then a DatabaseEngine
instance into this array. Call the Shutdown method from your Server instance.
Possible To Copy Form2 Three Times On Form1 With Different Variables In Text Boxes?
Oct 18, 2009I recently bought a barcode scanner for God knows what reason, just to play around and now it seems that its easy to sort out everything at house with it (e.g. Disc Collection). So I decided that I need a special program for it to get sorted with the collection. I am new to Visual Basic, but used to do programs with Java 6 years ago, but it doesn't seem to be any similar to each other. Basically I have a Microsoft Visual Basic 2008 and here is what I want to do:I have Form1 which contains of a textbox and a button (which will be Enter further), a textbox for total amount spent (which has to be calculated from Form2 and a nice background. I also have a Form2 in the same project, which contains 3 textboxes (Title, Price and the barcode numbers)So my problems are: As I said there are just 3 textboxes in Form2. Is it possible to copy Form2 three times on Form1 with different variables in text boxes? For example Form2 1st copy will have one Title in textbox, Form2 2nd copy will have another Title in textbox and etc. The Titles are in excel (.xls) file.That is a problem further, but my problem for now is how to make barcode scanner working. The barcode scanner basically reads barcode and inputs numbers in a textfield and automatically presses enter.As I am new, I do not know how to make this work. When I launch the program the textbox has to be selected rightaway, so that I do not have to use mouse. As it is selected I read the barcode and the numbers are in the textbox right away and Enter key is pressed (but I did not assign OK button with a Enter key and I cannot output anything now). So how do I assign the button with Enter key and the textbox? Now as the button is pressed (OR ENTER KEY is pressed) The text in the textbox has to be selected again (so that I can input a new barcode) and Form2 has to be called on a certain place of the screen (e.g. 200x100px is the starting location).
Now when the Form2 was called it read the data from Excel spreadsheet and now the textfield in Form1 is ready to input new barcode. As new barcode was read the same situation is happening, but now the Form2 is copied into a new place with new parameters (e.g. 300x100px is the starting point).Same for the third time, but on 400x100px.For the fourth time the Form2 is not copied again. However the parameters of the third copy are getting the new data. Parameters of the third one are going to the second copy, second copy to the first one and the first one is stored in a text file or somewhere else to use further. (I wanted to use up and down buttons to search for what I have scanned)
Create An Isolated Context Which Allows Declare Two Variables
Nov 29, 2011I put "isolated context" in quotes because I don't know what else you would call it. Basically, in C#, you can do this:
{ int i = 0; }
{ int i = 1; }
The curly braces create an isolated context which allows you to declare two variables with the same name in the same method or property logic. Is this possible in VB.NET? Also, what do you call this aside from an isolated context?
