Using Array In Other Subs - Public And Global
Jun 20, 2011
I have an array that I created in a sub with a button. I was wondering how I could use this array in other subs after it has been created. I tried making it public and global, but it didn't work.

At the head of a module, I wish to declare some global variables for use in various subs/functions.
What is the difference between.Dim x as string and Private x as string / Public x as string, and when would I use one over the other?

Is 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.

I have a form named FrmDrvouchers. It contains some public subprocedures.I call these subs from another form which opens from a form which is opened from FrmDrVouchers as a dialog.When I open FrmDrvouchers directly, everything works. But when I call FrmDrvouchers from another project which is also part of this solution, its public subs don't work when I call them from another (dialog) form.
Here is the code of the Button Click from which I open FrmDrvouchers:
Dim FrmDrv As FrmDrVouchers = New FrmDrVouchers()
FrmDrv.Show()
This works, but those public subs don't. Why?It just skip what i want to do, but not throws any Exceptions,Now I m posting my Code,,, plz have a look on that,,Here is my Main form's MenuStrip Button Click code :
Private Sub CashPaymentToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CashPaymentToolStripMenuItem.Click
Dim DrVouchers As Transactions.FrmDebitVouchers = Transactions.New FrmDebitVouchers()

Basicly I have a set of public subs, (not related to a form), inside a public class, and all of them share a variable. One of the subs, the one called for first gives the variable a value.
When the next sub is called, the variable is null. The data in the variable has been erased as the execution of the prior public sub ended I'm guessing.

I 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

I'm trying to make a public array that I can use in Form1.vb and module1.vb.
It seems to work fine in Form1.vb but module1.vb complains about that it isn't declared.
This is how I've done it: I placed it right after this line in Form1.vb:
Public Class Form1
Public SuffixArray() As String
how I declare a Array that I can use in all forms and modules?

I have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

i am new at everything VB.net/ASP.net. I have an ASCX.vb page that lets the user choose someone from a table. Once they do select someone, the page reloads with that persons information into another table below that one where they can submit an order for that person or remove that person. Problem being is that i wanted to store the users ID that are selected but it seems that everytime the page reloads to show an update, it dim's my array again back to default. This is my code once they choose a user:
