Globally Declare A Class?

Jun 1, 2009

I know you can globally declare a structure so every class knows it.But I have a class named "WPNConnection", but I was wondering if you do like.Public WPN as new WPNConnection but so every class in the whole project could access it. It's just annoying having to raise events to get back to the class holding it, or finding the main class and finding it declared there.

[VB 2008 EXP] Globally Press Keys Down?

Apr 5, 2009

I am trying to make a program that outputs a series of key presses into another window. I have been trying to do this with the SendKeys but have found that it it presses the key too quickly for the other application to be affected enough to cause much output. I need a way to globally press the key down and key it up over a period of time. If I know the code for pressing a key down and up globally I'll be able to link it up with a timer and work from there assuming the key codes are the same as SendKeys.

Add A Handler To A Publicly Created Object?

Feb 22, 2012

I'm adding some functionality to an app that was made a few years ago and I need to raise an event when the tabcontrol is clicked. However it would seem because the control was created publicy I can't add a handler to it? I never ran across this before. I stripped the code down to the bare essentials. As you can see in the image, if I Dim the control within the sub I can add the handler. But any handler created for the publicly created control fails.

Is there another way to create the hander in this case?

Creating Object Instances Globally?

Nov 19, 2009

this is probably something I should know, but I'm puzzled by this.I'm trying to create some objects and being able to access and modify these globally. I tried to create a Public Module and declare a few objects in this.I am able to access these from another sub, but I get an exception error when after building and runing the process and trying to modify these object. The same thing happens if I declare the object in the Public Class Form1. For example like this:

Public Class Form1
Public appWord = New Microsoft.Office.Interop.Word.Application
Public wordDoc as Microsoft.Office.Interop.Word.Document

Globally Declared Collection (List Of) Not Maintain Values Across App

Mar 10, 2012

I've been building a simple card game in VB using VB 2010 express. I've built a simple Card class, as follows:
Public Class Card
Public Property Number As Integer
Public Property Suit As String
Public Property Image As String
End Class

I setup a base deck to create the unique, individual cards, which will then be used in multi-deck games. I have a game table form where the cards will be displayed. I declared this base deck inside the game table form and built it during the form's load event:
Public Class Main_Table
Public baseDeck As List(Of Card) = New List(Of Card)
Private Sub Main_Table_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim myCard As Card = New Card()
[Code] .....

Everything runs fine up until the end of Main_Table_Load. I've inspected the baseDeck values and they are correct. But when the Build_Deck_Click sub is invoked, the baseDeck collection's values become all the same, specifically it becomes composed of copies of the last card I built. I've stepped through the code and expanded baseDeck to confirm that all Cards become the same. I've tried moving the Public baseDeck As List(Of Card) = New List(Of Card) to a different module, with the same results. Since I will be using the baseDeck list through the app, I can't declare it privately inside the form_load event, as I'd have to re-create it every time I need to use it.

VS 2008 Declare The Variable Along With All Declarations In A Module?

Feb 4, 2012

I have an issue with variables that are used to name For-Next loops. I have had this problem in a couple programs but not consistently, i.e. some variables work, some throw a warning (not an error).

The situation is this. I declare the variable along with all my declarations in a module-

Module MainModule
Public Counter1 As Integer
end Module 'MainModule

[Code]....

The type for variable 'Counter1' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Counter1', or use the fully qualified name (for example, 'Me.Counter1' or 'MyBase.Counter1'). In the past I've always broken down and changed the names to get rid of all those ugly warnings. Sometimes I have eliminated them from being declared in the module and declared them at call time. This is not how I program and I like to keep consistency throughout.

how I can get rid of this spotty, on-and-off nonsense? There is obviously a lot I don't understand about VS and I would have never taken it up but would have stopped 3 languages ago if I weren't forced into bulkier and bulkier languages (sorry about the rant. I feel OK now).
