Public Variables In Module "not Declared" Windows 7 64bit?
Nov 4, 2010
I 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.

I have a form intended to generate serial number and this serial number will be distributed to the other forms. I use to pass the serial number to the other forms this way:
if frm1.visible = true then frm1.txtserial.text = frmserial.txtgenserial.text
if frm2.visible = true then frm2.txtserial.text = frmserial.txtgenserial.text
if frm3.visible = true then frm3.txtserial.text = frmserial.txtgenserial.text
and so on....I want to have a method that will ease the method above. Is there a way to declare a txtgenserial textbox globally and the other forms will just refer to it?ex. Public genserial(tb as textbox)' that example is only a demo to what I wanted to get, this declaration is absolutely incorrect.

I have a .NET library that needed a COM wrapper around it so it could be called from VB6ish programs, in this case specifically Microsoft Access XP I have a type that's declared in one of the classes that went into the .NET library. I thought since its public, it would be seen, but it didn't show up in Access. And yes, we made the TLB file and registered the COM interface. I had to move the type declaration into the COM module, which I really didnt want to do. Is there a way to export a type/enum through COM without actually declaring it in the COM interface Scott Berger McCormick Systems

I'm converting a VB.net library to C# and having trouble finding the C# equivalent to a VB.Net Public Module.
In the same VB class is a With block. Any idea what the equivalent might be for that as well.

C uses B and B contains A (C=>B, B=>A)
Should I reference a in c ?

I 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?

I have a simple table in an access database that I'm using in a VS2010 project. I have a combobox control that a user can select the horse power of a motor. I then take that selected value from the control and copy it to a string variable called gstrSelectedHP. All I want to do is run a query that will pull up the full load amps of that horse power motor from the table. I have the query already, but I need to somehow put the gstrSelectedHP in the WHERE part of the query so that it only returns that value.

I have a public readonly variable in a module, but when I try to set it in my form load event for the first time I get 'ReadOnly' variable cannot be the target of an assignment. It is my understanding that a ReadOnly variable can only be set once and after that you would get an error when setting it.

I'm trying to create a generic Controller Class for generic events. But these these events still need to access their class variable. So my idea is to create the Base Controller Class with a ModelBaseclass variable as _ClassVar, which is inherited by all of the other class Controller classes will derive from. But I want the derived controller classes to override the _ClassVar with whichever one they need.
I want to do this, so the ControllerBaseClass can have all the generic functions that all the Derived Classes would use.
Model :
Public Class ModelBaseClass
Public Overridable Function Foo() As String
Return "Name"

Can 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?
[Code].....
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.

I 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...
