Using Modules In .NET Considered?

Jun 7, 2011

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?

IDE :: Windows Forms Classes Appear As Class Modules Not Form Modules In Project Explorer

Jan 7, 2011

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!

What Would Be Considered A .NET Module In C#

Mar 16, 2011

VB.NET has classes and Modules, so my first question is what is the difference? Also, I noticed that C# does not have modules, but just classes, is there something in place of modules or were they removed for C#?

Is Backspace Considered Character

Oct 18, 2010

You need to test for the backspace character, and if it's there, fix up the input.Maybe something like this:

If Right$(TxtQP.Text, 1) = vbBs Then
TxtQP = Left$(TxtQP, len(TxtQP)-1)
End If

Or is the backspace not showing up in the string, but as the input character kicking off your procedure?

Is Using GoTo<label> ALWAYS Considered Bad Practice

Aug 23, 2011

I'm just wondering why using GoTo<label> is so frowned upon?I'm learning VB, and I want to develop good habits as I go. One thing I don't entirely understand, is why everyone avoids GoTo like its the plague (except in error handling...). I feel like GoTo could be useful in some situations.

VS 2008 - Are Arrays Considered A Type Of Collection Like Lists

Mar 2, 2010

Ever since I started using VB.Net I have been using the Generic List collection List(Of <Type>). Arrays, I haven't used so much. I used them a lot more when I wrote C code years ago.

1.) Are arrays considered a type of collection like Lists, Dictionary, Queue etc are? Or are they in their own category.

2.) Can I iterate over an array with a For Each loop like I can with other collections or do I stick with the normal For loop for arrays?

3.) There are certain methods that return arrays. Can I set a list object to hold this return value instead of an array?

Are Modules The Same As VB6 Bas Files

Aug 22, 2010

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

Hide Both Of The Modules Upon Execution?

Feb 22, 2012

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?

.net - Using The Same Modules In Multiple Projects?

Dec 30, 2010

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

Are Modules Used To Organize Code

Apr 11, 2011

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?

IDE :: Modules Window While Debugging

Oct 7, 2009

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.

Merge Modules With Crystal 10?

Mar 23, 2005

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?

Same Name Methods In Different Modules Cause Ambiguity

May 20, 2010

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.

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.

Are Modules Still Commonly Used In Program Structures

Aug 18, 2010

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.

Forms :: Threading And Modules And Sleep

Mar 31, 2011

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.
