.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?

or else i would like to store important functions in modules of any one project and import the codecs into any of my project instead of rewriting

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!

My VB project is large enough that it requires several files. It was originally developed as a Console App and I created each file as a MODULE. All modules could use subroutines, data structures and constants from other MODULES and everything worked fine. I needed to add basic windowing to the app and this required that the app be converted from a Console App to a Windows Forms App. The main window is Form1 which is not a MODULE but a CLASS. The problem is that some MODULE based functions cannot access subroutines, data and constants that are defined within the CLASS Form1 unless they are incorporated into the CLASS file and this makes the CLASS file very large. If I add a new Class file to the project, it also cannot interoperate with Class Form1 in the same way that multi-MODULE code interoperates.
How does one spread CLASS code across several files and still allow it to interoperate as if it were in a single file? Alternatively, how does one create several CLASS files that operate the way multiple MODULE files operate.I am sure that there are all kinds of best practices that I am violating but the goal to to get some prototype software working and interfaced to some lab equipment.

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.

I am currently working on an application that is about 90% finished, and we just got an addition that requires us to create a new project in the solution. My question is, I have a bunch of classes created in the main project that deal with the database, and it has a lot of functionality that I could really use in this other project.

I have a large application with multiple vb.net projects. I have one .sdf DB file for all of the projects. My problem is that when I add records to the DB in one project, it is not available when I try to access the data from another project. The project is looking in the local DataDirectory for that project where there is a copy of the DB file. Is there some way that I can create one folder for the DB and have every project access it. When I add the DB to each project, it creates and uses another copy in the bin folder of that project. I have tried setting the connection string in My.Settings to a common DB folder with no luck.
I also find that when I use Server Explorer to make changes to the DB, all of my data is wiped out. I also don't see any records when I choose Show Table Data in Server Explorer. I am assuming that the records are in the copy in the Bin folder.

I've developed a stand-alone RTF project/solution and a stand-alone calendar project/solution. I'm trying to incorporate them into a master project/ solution.If I just add the RTF & Calendar projects to the master solution, I cannot access them from the Main form of the master project. It just doesn't see them. Just adding the forms doesn't work because it doesn't contain all of the necessary information embedded in the project (references, etc.)

I originally developed a simple application software [VB.Net + MS Access] (Lets call this project A) but now I want to include more functionality in it. I have an encryption/ decryption software utility (Lets call this project B ) and a Text to speech generation utility(Lets call this project C) . That is, I want to add Projects B and C to project A. [Such that clicking on the main form of project A calls a form from project B or C as desired].In solution explorer, I right clicked--Add Existing Project--and added both the above mentioned projects 1 by 1. (Added B and C to the solution explorer with the already present A).As the application software's (Project A's) main form is the main form of my project, I want to have a menu option on the main form (Of Project A) so that a user could click on one of the menu options and the main form of my other projects ( Project B or Project C or Encrypt/Decrypt or Voice Generation) should open by him doing so. To this effect, I tried the following:
1. I dragged the form simply from one of the projects (From B or C ) into the folder of my Application Software (Project A).This generated a lot of Build errors and the Voice Generation utility (Prj. C) would not work like this.
2. Tried to reference a dll, however the authors of Projects B and C did not include a dll in their projects.
3. Now I came to know that to call a form residing in another project folder or even another folder within the same project, you have to give a path for the form. HOW DO WE DO THIS?
As you can understand, I cannot copy the entire code of the 3 projects here....I will try attaching my project here though..Here it is: http: rapidshare.co...MY_Prj.zip.html[Dear Administrator: The downloading option on the webpage does not allow files bigger than I mb, thts why I used an external link]As I said, in the application, Project A is TMS.NET ; Project B is EncryptFile and Project is C.I encountered a problem while adding project C [spoken word], so the project contains only projects B and A. I will try to attach project C seperately.That is, TMS contains proj A+B and Speech contains C.

I thought I'd give VB a go after developing with C# for the past few months. I'm using Visual Studio 2008 and have imported the VB IDE settings. I'm going through the same steps in VB as I've gone through in C# to create my solution for an n-tiered ASP.NET web application, but the results are unexpected. Here's the steps:
1. File > New Project > Other Project Types > Visual Studio Solutions > Blank Solution .... name the solution & choose the location ...
2. At this point, I want to proceed to add projects as follows by right-click on the solution in solution explorer
a. Add > Visual Basic > Web > ASP.NET Web Application ... name / location of the Web Client
b. Add > Visual Basic > Windows > Class Library.. name / location of the Business Layer
c. Add > VB > Windows > Class Library ... name / location of the Data Access Layer
BUT, as soon as I complete step 2a, the solution disappears from solution explorer. "Show all files" is selected. This happens regardless of the project I create first.

All too often, when I am looking for sample .NET code to do something and actually find it, it is written in C#. I am by no means proficient with C#... I can read and follow the logic of C# or modify the code, though I have difficulty following along since everything ends in "}".So what do I do? I create a solution with 2 projects. I put the C# code in one project and VB code in the other project. The VB project references the C# project and I modify the C# as necessary so I can call the useful code from the VB project.The current C# code I'm working with is a rather large project. Specifically what it does is handle input from HIDs (specifically I want to use it for input from a media remote).What I wanted to do was leave the C# code pretty much alone and just call a VB subroutine when any HID input is received (many of the remote buttons can't be distinguished from keyboard keystrokes) and process them in VB. Problem is that the VB code also needs access to pieces of the C# code (circular reference). Ideally what I'd want to do is create a VB module within the C# project (since VB.NET and C#.NET are functionally equivalent -- mostly -- though syntactically different). I've used compilers in the past with similar functionality, though I don't know if VS.NET 2008 has this capability. If I just add a module to the C# project, it expects it to be written in C#.If I can't do that, I see 3 options:
1) Write my application in C#
2) Write a new class in C# that exposes the functionality I need, instantiate it in VB
3) Convert all the C# code to VB
These options are beyond my current skillset (except maybe 3), though now is just as good a time as any to learn C#. But this may require more time than I'm willing to invest. I just wanted to create a task launcher / application switcher to be able to switch between music, video, and other players. I, in fact, already have most of the VB code I need from another project, including a DirectX "cover flow" style interface. I just want to add remote control support to it.

Over the past months I have been working on small windows forms applications and learning vb as i go along. The aim was to pull these altogether into one big application.
I am now at the stage of pulling these together I have created a new project (called MainMenu) and designed all the buttons and interface. I have added my other projects (SISApp, CURApp) to this project. File > Add > Existing Project. I can see these projects in the solution explorer.
Now my problem. How can show Form2 in the SISApp project when I click ButtonX in the MainMenu project.
I dont just want to show Form2, i want all the functionality and the database connection in form2 to also work etc.

I have written a few different applications in the past few years, all of which are related in that they help users creating maps/levels for a certain game. I would like to 'bundle' all these applications together, into one application (and will later add more functionality to that). In it's most basic form, it would simply be one single Form with buttons, where each button opens the corresponding application.

I've been doing some lite coding over the last couple years so I'm no where near where a lot of you already are. So my code tends to be organized in the standard beginners format... one project per solution with one executable (*.dll or *.exe). So I have a bit of a "best-practices" question for you... Why use multiple projects in one solution?

How would i reference a control or form from another project. I have a solution with multiple projects (Project1 & Project2 for example) and I want a button on Form1 of Project1 to open Form1 on Project2. I know if they were part of the same project it would simply be Form1.Show() and I thought something like Project2.Form1.Show() would work but unfortunately it doesn't seem that easy.

I've got a StartUp project (StartupProjectA) in Visual Studio that references projects A, B and C. I've got all of those in SolutionA.My predecessor has previously added this solution to SourceSafe so that there's a SolutionA folder in SourceSafe, containing a StartupProjectA folder, and A folder, a B folder and a C folder.
It turns out, though, that StartupProjectB and StartupProjectC all live in the same directory as StartupProjectA on the local machine, so on the PC I'm using I have a [GeneralSolution] folder which contains a StartupProjectA folder, a StartupProjectB folder, a StartupProjectC folder, and A folder, a B folder and a C folder.My question is what do I do to get the Solutions for StartupProjectB and StartupProjectC into SourceSafe? I've tried adding them, but they all create their own copies of folders A, B and C. What have I missed?
I'm trying to use the Visual Studio SourceSafe integration to get these solutions into SourceSafe. Doing so creates multiple redundant copies of A, B and C. I would like to have one folder in SourceSafe, containing SPA, SPB, SPC, A, B and C folders. I'm not really sure how to do this, because I can only add entire Solutions to SourceSafe via Visual Studio. There's no option that I can see for "Add this folder to SourceSafe and recognise that these other three folders are already referenced in the repository and so don't need to be added."

I've developed a couple of different stand-alone projects, myRibbonRTF and myRibbonCalendar and have them functioning well. I want to tie these together with other projects in a single solution called myMain. When I add these projects to the solution, their forms are not accessible in myMain (e.g. myRibbonRTF.frmMain.Show()). I've searched high and low for the last week trying to solve this and the only nearby solution is to turn the other projects into .dlls and access them in myMain that way.

I have some assemblies that were developed using .NET 1.1. These are business layer assemblies that are required for other .NET 1.1 applications to work. I have been developing our new applications using .NET 2.0/3.5. I would just convert the business layer projects over to 2.0 and be done with it, but those old 1.1 applications just won't die.As such, has anyone ever had two different .vbproj files (one a .NET 1.1 project file and the other a .NET 2.0/3.5 project file) that pointed to the same set of files so they could be compiled appropriately?

I am using VB.NET 2010 with a solution that consists of class libraries and winform projects.
Each project has an app.config for it's specific needs. There are however, several settings that are common across all projects. I would like to implement a common config file to hold those, but that effort hasn't been very successful.
After much searching I developed a test program to play with and it was working until I moved the Globalsettings into a separate file. Below is a paste of my code along with the config files I've been experimenting with. I've added the references to system.configuration and made sure my config files are set to always copy to the output directory.
The code compiles, but GlobalSettingsLookup is never set to an instance of NamevalueCollection. I'm guessing it's because the ConfigurationManager can't load the section "GlobalSettings"(?) That's just a guess
My Code:
Dim GlobalsettingsLookup As NameValueCollection = CType(System.Configuration.ConfigurationManager.GetSection("GlobalSettings"), System.Collections.Specialized.NameValueCollection)

I have a windows forms application with one exe and several dlls(Class libraries) in a single solution. The application uses common data that is used across all the dlls. I would like to load the data when the application is starting up and use the loaded data at various points in the dlls so that I do not have to load the common data again and again. How can I share the data loaded in main EXE across the DLLs?

I'm sick of my EXE files only looking decent in one view in explorer (ie List or Tiles etc) because I can only figure out how to specify one icon file for my projects so it has to be a specific size and if its too big it looks rubbish at smaller sizes in explorer, and vice versa if its too small. So how can I embed more than one icon file and make it automatically select the correct one to display in explorer depending on the view? I believe you can store more than one icon in an ICO file, so do you have to just combine the various size icons into one ICO and then explorer will automatically select the correct sized on? Or is it something you have to do within the VB project?

I have a solution with two projects. The main project connects to the second project via a reference, and the reference path is local to my machine. It looks like it references the .exe file.So when I publish the main project (ClickOnce), i get the following error:
Application validation did not succeed. Unable to continue.In the log file, under Error Details, it says
System.Deployment.Application.InvalidDeploymentException (RefDefValidation)
- Reference in the manifest does not match the identity of the download assembly Project2.exe
- Source: System.Deployment
How can I include this second project? Should I publish it, then reference the published files? What do i reference? The .application file?Is there a way to just include this second project, so when I do publish the main project, the second one just goes along with it?

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?

Public Sub SaveList(ByVal List As ListBox, ByVal filename As String)

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?
