Public Variables In Module "not Declared" Windows 7 64bit?
Nov 4, 2010I have a VB .net application which works fine on a 32 bit systems. We tried using it on a 64bit Windows 7 system but it failed. So I set up an environment in a VM (windows 7 64bit VS 2005 SP1 all updated) and started debugging there. The problem I come across is, I have a module (Public variables and function declarations from a driver provider FTDI). When a function from module is called the result is saved in a variable also from module. But the problem is the variable is not declared.

Nov 2, 2009I have a situation where I have several VB.NET Modules in the same Logical-Module of a large application. I would like the update function of each module to be public, but I would like users to be forced to qualify the function call with the module name.
ModuleName.Update()
instead of
Update()
Is this possible?

Public Properties Within VB Module - Cross-client Behavior
Oct 15, 2010Can one client call a public property within a VB.NET module and see the value of that public property changed by another client accessing it at the same time?

I'm running into random instances where it looks like another client might be modifying (by setting) the value of GetSetDateTime DURING the first client's run through of WhateverMethod(). This is alarming to me and I've been trying to figure out if that's a possibility.
Public Sub Label Changes On A Form Don't Work When Called From A Module?
Dec 15, 2009I am writing a control application for an inteface card. The complicated work of initialising communication with the card is written and working fine. However, my problem is to update the text in a dialog label on the communication interface form from a module that contains all the coding for accessing the inteface card. From the module, the interface dll returns data that describes some typical connection errors and the module then calls on Public Subs in the form to display error messages; for example:This is the Public Sub in the Module that initiates communication with the interface card:
Public Sub OpenDeviceInterface()
DeviceID = 1 - My.Resources.DeviceID
h = OpenDevice(DeviceID)
Select Case h
Case 0, 1, 2, 3
[code]....
What happens when these Public subs are called from the module is that the MSgBoxes I made to test the routine show up but the label text doesn't appear.I've tried; Refresh, on the label and the form without success...

Declaring The Public Variables?
Sep 23, 2011I've created a 30 point wizard. Every step gathers between 1 and 3 variables. I've created a module and publicly declared the variables there. At the end of the wizard, one master form opens, gets all the variables, and displays them on one form. At this point calculations are run too which populates more variables. This works fine for one instance of the process.
the user may want to be running two instances of the wizard at once. Obviously, if the previous wizard is part complete and they start a new one, the variables are going to get crossed or replaced by the new wizard.Is there a way for the variables to be declared publicly but used in multiple instances?
Setting Variables In A Module?
Mar 7, 2011I declare a variable as FRIEND in a Module. Then I instantiate that variable in a Sub in the Module. After the Sub runs, when I try to access that Variable, it is always NULL (Nothing).
Module MODULE_Main
Friend MyClass1 As Class1
Friend Sub Main()
[code]....
How do I get MyClass1 to persist, meaning how do I get access to that variable outside of the Sub that instantiates it?
Cant Access Public Variables From Another Form?
Aug 25, 2010I have a string on my main form called String1. When I open another form, I need access to this value. In the form I open, I have always done something like:Dim NewString as String = Main.String1
This has worked in the past. Well, I ended up renaming my forms (from Form1 to Main) in the property window and it now when I type the above code, it does not list Main as a form. Nothing that I renamed seems to exist now.

Dynamically Concatenate Public Variables?
Mar 10, 2012This seems basic but here's my problem. I am trying to build my connect string as a public variable that will connect to either an express version of SQL Server or a non-express version. The app.config defines it as being express or not and is modified to the user's choosing when it is deployed using the a firstRun routine.
The problem is that even though I'm modifying the value of the variable SQLexpress when the app is initiated which in turn should modify the value of the variable g_strConnectionString it doesn't. The value of g_strConnectionString will always take on the initial value of SQLexpress. I know I can define 2 separate variables for the connection string but I'd prefer not to have to change all of the references throughout each of the various programs in this system as they all have the same issue.
So in the following load event I've traced it and when it sets globals.SQLexpress = "", I then look at the value of g_strConnectionString and it still contains "SQLEXPRESS". It seems I need to somehow force vb to refresh this variable after it's been changed.

VS 2010 Public Variables For All Classes?
Mar 30, 2011I have a MDI application and a very complicated class there which populates its properties from a dataset derived from an external database. Each form, including child forms have to be able to access that class and use its properties thorughout the whole session.I don't know where to 'preserve' these property values within the application. I kmow many books etc. suggest not to use public variables but I really can't find a way to solve this other than to use a public variable (which is a list(of my custom class) in this case.
I have a separate class called PublicItems.vb and declared there my public variable as
Public Shared secuniverse As List(Of myCustomClass)Is there something wrong with the syntax because if I try to use the variable secuniverse in my main application class, I get the following exception:'sectoruniverse' is not declared. It may be inaccessible due to its protection level.
