VS 2008 How Many Modules Can Have In One Program
Sep 8, 2009
I am doing a VB.NET course, there is a question in one of my assignments - "How many modules can you have in one program?" This seems like something that should be easy to find, but I have not been able to find it anywhere.Can anyone direct me to a resource that would have this? My initial thought is unlimited, although in practical terms, if you have an excess number of modules, then you probably need to re-think your workflows.

Yesterday I opened Visual Studio (2008 v 9.0.30729.1) and all the winform classes in my project display with class module icons with the little 'VB', instead of form module icons with the little form icon!
When I double click on a form module, the form designer doesn't open, just the code module.
When I run the project, it runs fine. There are no errors. The project builds fine.
I did Project --> show all files, and I can see the designer and resx files below the form module which doesn't look or act like a form module.
I can't open my forms to design them!

I am not a program designer by any means but I would really like to start getting a better grasp of how to do it and a better understanding of the .NET languages in general (VB, C#). I was reading a book by Wrox - Professional Visual Basic 2008. In it I believed it mentioned that Modules are slowly going out of existence. I can see why most coding would go into a class object but I would assume modules would always be necessary to at least keep the code clean.
Also, I have been searching for a good source on software design but I can't seem to find any recent books published. I might be searching in the wrong places but I would really like to get my hands on one.

I have a contact manager program that I'd like to design for multiple network marketing companies. My desired structure would include a core program which covers basic contact management functions. After that one could purchase a module for their specific network marketing company. This module would contain a variety of controls that the original program would need to be able to manipulate. Here is an example of what it would have to have:A group box containing buttons that link to a genealogy view, and the option to import one's donwnline from the back office provided by a company.A panel which is displayed on the contact page allowing the user to input business information or which will be filled by importing a downline from the back office: ie business ID, qualification level, sponsor information etc.a panel displayed when one searches for contacts on the contact list page which allows the user to sort based on information such as when they joined, what their business id is and so forth.a panel which is displayed in a personal business overview page which presents to an individual how many people in their downline are at each qualification level and develop a mailing list for individuals of a certain qualification level.
I have the code developed to perform all these functions, I just wanted to give you an example of what needed to be done. I'm thinking that what I'm trying to create is a library that one can download and the program will recognize, but I'm not really sure where to go. What I'm really trying to do is figure out what kind of file I can make that will contain all this code and the GUI information that the program will recognize.

I want to start learning/using modules instead of integrating the code directly into the program. So, I tried to make an example. Basically, what I wanted the program to do, is I click button1 and it lists details about my computer. So, I added 7 labels to the form, and a button. Then, I added a module (Module1.vb)

I have a program that uses a tabcontrol. Each tab represents a collection of common tasks and, as one would expect, has a bunch of controls on it.
In my original version of this app, I simply put all functions/subs/etc related to a specific tab right in the main form class; I just divided them with lines and a few extra blank CRLF so I could jump from section to section within the code (literally named Tab1 Code, Tab2 Code, and so forth).
I am re-working the program and thought I'd use modules for this instead. So, I built all the forms and grabbed the code from the previous version, created a new module, then pasted the code into the module. VB.Net 2010 has choked all over this with a zillion errors. The functions/subs are all public, but they cannot see any of the controls on the main form. Every control that is in existence on the main form comes up as being not declared in the module.
This is the first time I've tried to use a module without a full class, and the first time I've tried referencing back to controls on the main form in this fashion (I've always just used it for functions/subs that I pass data to). Am I trying to do something here that shouldn't be done or...? I basically just want to create files so I can segregate the code into a more logical design.

i have a main module called "main", within the module i have declared 2 other modules "Interfacing" and "Espec", within these 2 submodules they both have a structure called "coord" which is identical. The problem is that when i have defined a function in one module with "coord" as type and try to assign a value in the other module with coord type i get error message "Value of type Main.Interfacing.Coord cannot be converted to Main.Espec.Coord", so basically how could i pass that structure?

I have a project with several forms and modules. The problem which I am mentioning revolves around 3 items : 2 forms (e.g. form1 & form2) and a module. (Using VB.NET 2008, .net 3.5)
Now I have a structure declared in a module. I have a variable of that in form1 and form2.
'Module Code
Structure MScanner
Dim Indicator() As MuseIndStru
Dim FName As String
[CODE]..............
Now what is happening is, I am passing structure variable MScan (Form1) to Form2 (see function of form2 InitFilter) byvalue. Then in form2 I am changing value of a copy of the structure (see variable MS being changed in a private sub). But then when I close form2, form1's variable of MScan also get the value of variable MS (declared in form2).
I don't understand as this is not suppose to happen. I have reloaded my project as well but this problem is there. Why is my form1's variable value MScan being changed by form2.

I have 2 console apps projects in the same directory but different projects. There is some common code in the App_Code directory and a common app.config which gets build into seperate .exe.config files.One module (VScanDemonStarter) starts up and writes to one logger with its own appender going to a seperate file. It uses an process.start() to execute the other module (VScanDemon) in another command prompt hidden window.When I run VScanDemon by itself it puts entries into its log file. When I run VScanDemonStarter it puts entries into its (different) log file, the VScanDemon log file gets created, but no entries. I can see it is executing because some files get moved from one directory to another. Just no Log entries.

<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >

I am trying to create an application that can have "modules" added to it. For example firefox can have firebug installed into it. I am trying to figure out how I can write my code so that other developers can put their controls where they want to and my program will know to use them. I am assuming that this is called making a framework.

using bas files in visual basic 6 because I could write functions or subs that I would just easily use over and over rather than keep rewriting code. Do these work in the same way in .net? If anyone has any good info on modules like how to start writing functions and subs. Assuming of course that they work like vb6 bas files. If I were to make this sub a function how would I do this and I am assuming the benefit of this specific example would be a Boolean to check if if saved the text file or not?
Code:
Public Sub SaveList(ByVal List As ListBox, ByVal filename As String)
Dim i As Integer
Dim w As IO.StreamWriter

During the design of a new application I was wondering if using a module with properties is considered to be a bad practice. Some example code:
Module modSettings
public property Setting1 as string
public property DatabaseObject as IDatabaseObject
End Module
The code above is just an example to emphasize my question. In the past, this structure was used a lot in VB6. In the past I used it as well in my .NET projects.
But nowadays with buzzwords like Dependency Injection, Testability and Separation of Concerns the above structure smells bad. I can't really describe why, but it just feels wrong. I must admit I'm not very familiar with the keywords above, yet.So I'm wondering whether the above code really is a bad practice. If so, what would you use a Module for?

What advantage is there, if any, to using Modules rather than classes in VB? How do they differ, and what advantages/disadvantages are there in using modules? In VB or VB.NET, I use both.

I have finished creating the code for my client/server application although both parts currently execute modules/in console(this was for testing purposes).I am now looking at making both parts of the program completely invisible (they will eventually be executed as a Windows service upon startup). How do i go about this? Does the code need to be copied in to a "Windows Service" project, or is there a way I can hide both of the modules upon execution?

I'm using Visual Studio 2010 and coding in VB.NET.
My problem is that I've collected all the modules I've written and intend to reuse and placed them in a separate folder. When I want to add a module from the above folder to any given project, it takes a copy of the module and places in the project's source code folder, instead of referencing the module in the folder containing all the other modules.
Is it possible to include a module in my project and leave it in the folder with all the other modules, so that when I improve upon a module, it'll affect all the projects that uses/references that module. Instead of me having to manually copy the new module to all the projects that uses/references the module. Right now I have multiple instances of the exact same module that i need to update manually when I improve code or add functionality?

Im writing a application in visual basic to tell the user about their pc.
All this is in a module
Imports Microsoft.VisualBasic.Devices
Imports System.Management
Imports System.Net
Imports System.IO

The problem I am having is that if one of the things in the module fails such as if the users graphics card does not have any onboard memory then it will fail.This is causing everything else to fail aswell.I am very new to visual basic so ifyou could please excuse me if I have made any stupidly obvious errors and any suggestions are welcome

I have been brought onto a project where a large amount of code has been written. Most of the code is appearing in the MainWindow.xaml.vb file (yes, this is a wpf project but I think the question is appropriate for this forum). The folks who developed the previous versions in Visual Basic 6 told me that they organized their code by using Modules. I was not aware of this practice and I have actually never even used modules. Can I use modules in this way so that I can logically group different areas of functionality within the application? Or is there a more preferred method?

I have read many many forums regarding the error message "No symbols have been loaded. The breakpoint will not be hit." I had this error message come up a while ago, so I opened a previous version of my project, and copied the newest version of the code I am working on into that project. Then when I debugged, everything worked fine...for a while. Then I got the error message back, so I did the same thing again, and who would have guessed the error message returned, out of the blue. I am working on the program and it works fine, then suddenly one time when I try to debug with a breakpoint I get that message again. So I did some more research and I found a post that recommended looking at the Modules window while debugging (under debug > windows > modules). And in this window under my project, it said "Cannot find or open the PDB file". However, I compared this to the previous version of the program, that works fine, and I noticed that under Path, for my project, the path that I see is not the path where my project is located. So what I am asking is can someone please tell me how to change that path to the correct path where my files are actually located? I believe that if the path is correct, it will find and load the symbols.

I have learned that if I want my crystal reports to work on the client machines when they install my program, I have to include some merge modules. I have VB .Net 2003 and Crystal Reports 10. The merge modules that are included with VS Studio .Net 2003 are not included in the program software I have. Is it possible to download these merge modules somewhere else and use them with my software? If so, can someone give me a link on where to get them?

I have a Module in VB.NET called Math.vb and in that module, I created a Function that displays returns the percentage of one number to another. I have a Sub that calls the Function and I call the Sub from my Form1 class. Is there an advantage/disadvantage to putting the function in the class or the module?

I have 2 modules. Each contains a Sub with the same name. See below:
Module moduleA
Public Sub f(ByVal arg1 As myType)
Console.WriteLine("module A")
End Sub
End Module
Module moduleB
Public Sub f(ByVal arg1 As myType, ByVal arg2 As Boolean)
Console.WriteLine("module B")
End Sub
End Module
But the compiler complains that there's ambiguity between moduleA and moduleB. I have totally different signatures. However, if I put the 2 methods into the same module, there's no ambiguity at all.

I have a big project in vb.net with over a 400 forms and datasets and 100 reports. I deploy it using clickatonce. I want to split it into modules so each user will use the core project plus the modules his department needs, so when I make an update to a module he will take only this update and not the whole project as I am doing now.

Is it ok to use some classes and modules inside a single VB file ?
At present, I used to create them in separate files by choosing Project menu --> Add Class/Module
I was thinking about combing them into one file. Is there any merit or demerit on this approach ?

I have a frm_Main, which starts a thread. The thread then goes and calls a module, which has a thread.sleep() in it. This causes the mouse to freeze up while it sleeps, despite being called by the child thread. I thought this would have be on the thread time-slice? However it is causing my form to freeze for the sleep duration.
