Now problem is I cant make it available outside the procedure, and declaring it globally throws error.Is there any way to make it global?
I have something like

It only calls once the function and doesn't call it subsequently. How do i make it calls every 2 seconds?
I'm using a Threading.DispatcherTimer and every tick of the timer runs a subroutine. Is it possible that if the subroutine takes longer then 1s for the processor to finish that it will mess up the time of the timer that is counting in seconds?

View 2 RepliesIs there a way to keep from extensions from appearing as global subs, even when you are not dealing with the relevant type? I guess from how they are created, they always show up as global functions whenever I use intellisense, which, depending upon how many extensions there are, can be a pain. I want them to appear only as methods to the relevant type variable.
View 3 RepliesI have an array of comboboxes on a form. They are declared at the beginning. I wish to make these global variables so I can access them in another form. This does not appear to work.
Code something like this:
Public Class SecondScreen
Public OutputSelectControl() As Combobox = {O1, O2, O3, O4}
Where O1 O2 etc are the names of my comboboxes on this form. I wish to be able to address them from another form like so
localformvariablehere = OutputSelectControl(integervariablehere).Index
evrytime i add new controls to a form in vb.net the designer regenerates code and asks me to make corrections, so i have to keep on changing the object declarations to global using the 'global' keyword evertime it regenarates code,especialy dataset objects.how can i prevent this?

I want that global variables that sit in some DLL will be seen from other DLLs and EXE of that project.
I included in that VB file "Option Explicit On" as the first line .
But still no one can see my variables that were defined in that file . I made that all DLLs of that project depend to that one with the definition
I am using module and all my variables are public .
Option Explicit On
Module LPSoft_Core
#Region "Public"

I have a variable whose scope needs to be global, because it needs to be called in a function as well as in a button press. So I declared the variable in a Module so it would be global.The problem is that the value of this variable needs to be equal to the value of the text property of a textbox in the form.You enter a string into the textbox, in this case I entered "Hello". Then you click the button and it displays what you wrote.You click OK in that message box and change the value in the textbox. In this case I changed it to "Goodbye". Then I hit the button again, but the variable did not change values and the messagebox displays "Hello" again.

Here is the entire source code:
Module Module1
Public strDataValue = frmTest.txtDataValue.Text
End Module
[code]....
Note: This is just a demonstration of a problem I'm having in a much larger program so the variable does have to be global.
If we declare a global variable in module in vb.net, we can use that variable in anywhere in project.
How can we achieve same thing in C#.
Previously when we tried to convert a vb.net project to C#, we succeeded in removing the syntax error but we can't access global variable in a form.
I need some solution or guidance. Where I am making a mistake?
I need to add the code below to my global.asax file. It begins with a Sub Application_BeginRequest . My global.asax already has a section that begins with Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) I'm assuming that I should not have two sections with Sub Application_BeginRequest I tried putting the core of the new code into my existing Sub Application_BeginRequest and it returns no errors but it when I try to view the website in VWDE 2010 it times out. Something is causing it to run or load slowly.
This is the code that I'm adding:
<script runat="server">
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)

View 5 RepliesI want to create a dataset that I can access from any form. I already created the tables and columns using the dataset designer. I read that I can declare the dataset as public in a module, but when I try to access a table I have to put the name of the module in front otherwise I get a "Reference to a non-shared member requires an object reference" error. When I declare a variable as public in a module I never have to specify the name of the module to access the variable, so why do I need to do it for a dataset? The code in my module is:

View 1 RepliesI'm trying to build a language dictionary in VB NET in order to be able to have several languages in the application.This dictionary has a init method that loads from database the entire dictionary and stores it in memory.In the rest of the classes of the project, I added the reference and I can use directly the object without create a new instance because their methods are shared.
how i have to load the dictionary content in order that the rest of classes only accessing to Language.GetWord method obtains the properly record of the collection, same way as My.Settings class.When My.Settings is used from any class the values are loaded. I'm looking for the same effect.This is the code of the class:
Public Class LanguageProvider
Private Shared CurrentLanguage As Collection
Public Shared ReadOnly Property GetWord(ByVal Label As String)
[code]....
Function LoadLanguage must be called when the application loads, in order to access once to database. After that property GetWord must access to the collection with the words and return the result. The problem is that the instances are not the same and the dictionary is not loaded when a class uses it.
Im creating a desktop app with multiple forms. My ideal aim is to create 1 MenuStrip to use throughout the different forms (the same MenuStrip) appears on the different forms. otherwise I'll be copying the MenuStrips from 1 form to another and copying the Event code. What is the best way of doing this? I've created UserControl, put my MenuStrip on it along with me Code, then I load an instance of it whenever a new form loads. This seems to work fine until I want close the Main Form. I've tried ' Me.Hide ' but that just hides the UserControl. So the MenuStrip appears on Form A, when i click a Menu Item I want it to close Form A and open Form B.

I want to get the global cursor with GetCursorInfo. I have found these things in MSDN library:

What I want is a Global Error Trap that will not stop code execution. What I have found is examples where each module requires some code or a Try block. I need it to be totally generic. Everything from UnHandledExceptions to conversion errors.
If I have to use try blocks all over the place then it is not Global Error Trapping.
I need code at the highest level possible that will always catch any and all errors reported by VB.[code]...
