I’m not sure if what I am trying to do is possible, but surprisingly VS2008 seems to let me copy a .cs file directly into my VB.NET project. I then thought that I may be able to use the class in this file directly from VB.NET. However, it doesn’t see it when I try to reference it in. Is what I'm trying to do possible, or is VS2008 simply treating the C# file as a resource file or something?
You should reference CS project that contains your class written in C# from your VB project. This class should be public. After doing it, you will be able to use this class in your VB project.
You'll need to add a C# project to the solution, rather than just copying the source file. Just create a new project making sure you select it as a C# class library or similar and make sure you add it to the current solution and then copy the source file into that.
Maybe you want the c# code translated into vb, then be sure to have a look at

there are many code converter but is the best I know.

Hi fellow programmers,
I'm creating a ControlLibrary for future project's that uses the amazing MaterialDesignXaml library. In this ControlLib I use the MaterialDesignThemes.dll that contains several styled controls, resources and classes.
Now my problem is that I need to use the same dll's in the real application (sae sollution for now). If I want to use the mentioned control library in this project (as project reference) I always get this error:
Dll Error in Application Project
.
I understand the problem the compiler has with this, since It cannot check if two refrences (from seperate projects in the sollution) are the same dll. But how can I fix this?
The strange thing is that the designer complains like in the screenshot, but the application runs just fine...
I'm using TortoiseSVN for Version Management, maybe this has to do something with it?
Any idea's?
Can i make obejct of a VB class from C# class, if possible then what i'll have to do?
Yes. You'll have to compile the VB class using the VB compiler first. The easiest way to do this is to have the C# code and the VB code in separate assemblies, in separate projects. You can then include the VB project as a reference in the C# project and use it that way.
You can certainly use a class in a dll created in vb.net in a C# project. However you won't be able to do that natively inside Visual Studio for the same project.
1) Add reference to VB library you want to use.
2) Add namespace in your code.
3) Create your object and use it.
(VS 2008)
I'm using a C# library for my VB.NET project. And the method summary/notes or what they are called do not show in intellisense. Is this supposed to be like that? Or is there something I must do to fix it? And if not, will VS 2010 be able to do this?
EDIT: Still unresolved. Now building library dll + xml file, but how to import the xml file in my vb project?
See image: http://i52.tinypic.com/25kh5xw.png
In C# library, go to the properties on the build tab, and check the checkbox for including XML documentation and specify the name and path. After that include the new library in your VB.Net project.
one reason could be resolved by importing the namespace needed
another reason could be due to faulty writing
if you send the code where the problem is we might be able to help you
If you're using source control (TFS or Github) then you need to the following:
Check in ( Push) for safe return point (base line)
Delete the references from the project.
Delete the custom dll's from the solution.
At this point the libs are marked as [removed], if you would add them again at this point, they will just be marked as [changed] again. This did not include the summaries for me.
Check in (push). dll's are now removed from source control as well.
Drag and drop the dll's (including xml) into the solution (I recommend using this method for including dll's
Add references to these dll's via Browse.
Check if you have summaries.
Check in (push).
Hi kind of a newbie question.
So apparently this library is popular for this sort of thing:
http://extracting.codeplex.com/
When I download that all I get is a .dll
I can't find documentation on their api, I don't know what I'm supposed to do with this .dll (I know how to load in functions from DLLs and such, but how when I don't even know whats in it?), can someone help me out.
start a new c# project. Open the add reference dialog and use the broswe tab, select the dll.
now open the object browser - you will see all the functions etc
edit: of course you can also download the source code from codeplex; always the ultimate form of documentation
There's a link on the same page pointing to the API documentation containing sample usage.
There is a link to an example on the codeplex site
http://extracting.codeplex.com/wikipage?title=Web%20Data%20Extracting%20and%20Analyzing%20Framework%20API&referringTitle=Home
They have limited documentation on the codeplex site, available here.
I would recommend checking that documentation to see if it meets your needs, and asking any addition questions in their Discussions Page.
To use the functionality of the DLL from your project, right click on your project file in the Solution Explorer and choose "Add Reference..". You will be presented with a dialog to choose the reference you want to add. To choose the DLL from this library, browse to it from the Browse tab.
Once you've added the reference, you won't notice a whole lot of difference - all adding a reference does is give you access to the classes that are defined withing that DLL (called an "Assembly" in .NET terms). Think of it like getting a new set of "built-in" classes in your project that you can now use. You'll want to find some documentation or ask for help on the site to learn how to use these classes.
if you are using visual studio, you can just include the dll into the reference folder of your project and then use the "using" keyword to include the library into your namespace ...
If this is a .NET assembly, then reflector will tell you what classes and methods are available. You can also reference the DLL from a C# project and then press "ctrl-alt-j" to bring up the object browser to see that data inside of Visual Studio.
You can download the source code from that page.
Look at the classes and namespaces. You can add a reference to the DLL to your project and add "using" with the namespace of the DLL to the top of any code files you need to use it in in order to have access to the classes.
Additionally you can look at some of the examples posted.
Load the dll into .net Reflector. This will list the contents of the dll and any code comments associated with the API.
I am developing a GUI based application in MS Visual Studio 2005, I just want to
know if it is possible to use both VB.NET and C# in the same project. Or can I include a module written in C# in my VB.NET project?
I have a class written in C# which I want to use in my VB.NET based project, so if I can include and call functions from that project than I won't have to write the class again in VB.NET.
So please help me as I am new to .NET programming.
I just want to know that is it possible to use both VB and C# in the same project.
No, not in the same project. On the other hand, you can use them in the same solution.
Or can i include a module written in C# in my VB.net project.
I propose that you create a solution containing two projects: one in C# which forms a library that you use from your VB project. This is straightforward, easy to maintain and easy to extend.
I've never done it myself, but I know you can compile the C# code into a dll and then load and reference the dll in your VB project.
From "Calling C# class in VB.net":
I think the C# code that you want to
use must be compiled as a DLL. Once
that is done, simple add a reference
to that project to your VB.Net
project, import the namespace you
need, and then you can use the C#
code.
Also see How To: Create and Use C# DLLs (from MSDN, for VS2005)
You also want to ensure that you C# code is CLS compliant. This means that it won't publicly expose any functionality which other .NET languages won't understand (for example unsigned ints - which don't exist in VB, or differing classes only by case - since VB is not case-sensitive). To do this you need to add an attribute so that the compiler will raise errors if you have broken any of the guidelines. This article shows you how to do this:
The CLSCompliantAttribute can be applied to assemblies, modules,
types, and members.
For marking an entire assembly as CLS compliant the following syntax
is used
using System;
[assembly:CLSCompliant(true)]
For marking a particular method as CLS compliant the following syntax
is used
[CLSCompliant(true)]
public void MyMethod()`
Put VB.NET and C# code in separate projects. (I am using both VB.NET and C# in my open source project, http://msquant.sourceforge.net/, and it works great).
You don't need to worry about DLLs, just reference the project (use tab "Project" in the "Add Reference" dialog box). E.g. if you need to use a function in the C# code/project add a reference in the VB.NET project to the C# project.
You can't use a C# file and VB file in the same project. You can, however, have VB and C# projects in the same solution and reference them.
In your code you can use:
Imports namespace
or
using namespace
Once the reference has been added to the appropriate project build the solution and you are good to go.
You can also create a VB.NET Library in a separate solution, compile it and import the DLL into the C# Project or vice versa.
You must also know that if you have a VB.NET project with a C# project in the same solution with one of them having a reference to the other, changes apply in the referencing project will just be available to the other after rebuilding the solution. It's like having binary reference, but with the capability to change code on the same solution.
Personally, I don't like this, but I'm always in the situation where I modify the code in the referencing project and don't know why my changes are not in the code where I use it and I figure it out, oohhhh, I must rebuild.
For temporary help, it could be acceptable but not for programming every day.
If you were only planning on using the module in Visual Basic projects, then you should consider just converting the code to Visual Basic. If you need to use the module in both C# and VB.NET programs I would use one of the solutions posted above
You might try something like *Convert C# to VB.NET. It converts C# to VB.NET code. I use this page exclusively when I have to convert something I find on the net that was written in C#.
