I have a question about C++/CLI and Silverlight. I am currently working on a projet using the MVVM pattern where :
The business logic is written using C++ DLLs and a C++/CLI wrapper
I use a Silverlight application for the presentation part.
So I have to use my C++/CLI project in my Silverlight application, however, I can't because my project it's not a Silverlight project.
I've looked on the internet, where I found no suitable solution for my problem yet.
Therefore, I hope that you have a solution for this particular problem.
For the record, I work on Windows Seven using Visual Studio 2010, .NET 4.5 and Silverlight 5.
Thank you.
P.S: Sorry for my English, it's not my mothertongue.
The best solution I found is to create a wcf service which calls the c++ functions.
However, you must use a HostServiceFactory in order to make your web services able to find your dlls.
Thanks for your answers

sorry if this is too simple to be of help to most people.
This is the first time I have done anything remotely like this and it appears that my problem is too unadvanced to be covered in any documentation.
I am trying to connect a c++ project in Visual Studio 2017 to a PostgreSQL database.
Just to be clear, I know how to run pgAdmin/host databases, code in C++, and I think I could handle the npgsql syntax if I got it working.
However, I've never used .NET (although 4.5 is on my computer).
Here's what I am doing:
I start an empty project for C++ in Visual Studio 2017.
I open nuget manager and search npgsql, but my project is pointing to native,v0.0 instead of a .NET framework.
So I target v4.5 in the .NET framework property, but that doesn't change anything.
Could someone please tell if what I am trying to do is possible?
Should I be using a different project other than empty project?
Does this need to be some kind of web application?
If it is possible I'd love any advice on how to do it.
If you are writing a native c++ program it is very unlikely you want to bring in a .net assembly. If you want to connect to a pg database I would suggest instead that you use the odbc driver (https://odbc.postgresql.org/) or perhaps there is some library available as part of PG, but using a .net assembly will require a great deal of unnecessary interop work.
C++ is by far my language of choice. However, I have only developed libraries and console applications.
I like how in Visual C# you can easily design a GUI for your application - simple drag-and-drop controls and edit their properties simply.
I have tried to create a windows form application in Visual C++, but it uses the CLR/.Net. Is there a way to make a windows form application in Visual Studio without having to use the CLR or .Net? I really love how easy it is to design a form application in C# or VB.NET.
Thanks!
No, the whole concept of a .NET application is that it leverages the .NET framework to do all the cool stuff you mentioned. If you were to elaborate on what it is you are trying to accomplish we may could recommend an alternative solution, but if you write a C# winForms application it's going to need the .NET framework to run...
EDIT:
You could use a qt ide, or possibly a QT plugin for visual studio. Check this thread out:
Best QT ide?
I saw some Youtube videos that claimed they showed how to build a C++ applications using Winforms.
As far as I knew you needed something else like QT. Is it really possible to build using the same WinForms you would use to build a C# application but with C++ instead?
WinForms is managed code and is usable from practically every language with runs on the CLR. So standard native C++ can't build a winforms app. However managed C++ or C++/CLI can build WinForm apps in native code.
In general though I would question why you were doing this. If you are willing to have mixed mode C++ it would probably be much faster to
Build the UI in C#
Communicate with your native backend through a mixed mode C++ layer.
In VS ('05), you can go to File->New->Project... Then Visual C++ -> CLR -> Windows Forms Application. Have fun :)
I have to create an application for testing that is relatively simple. If a user plugs in a device into a USB (hid library), the form will say "Pass". If no device is detected, it will say "Fail".
I want to create the app to run on WinXP+. It must be a forms application as it needs to be visual and have colors. The biggest requirement for me is that it must be stand-alone (a user just double clicks, the file and it opens, no installation). I need to avoid installing any extra .dll files and want to avoid the .net framework all together. It has to be written in C++.
So my question is, what are my options? I am new to Forms applications and the only forms application I have written required the .net framework.
From my research, Visual C++ seems out of the question as it requires .net for Forms apps. What about Turbo C++ by Borland? It seems outdated, but can it do the job?
I would suggest Borland C++ Builder 5 or 6. Visual C++ lacks the functionality to create C++ form apps, if we dismiss MFC
I'd say Visual C++ would probably still be your best option. A standard simple Win32 C/C++ program using only the native API will should suite your needs just fine. If you're targeting XP+, then the only dependency would be "msvcrt.dll" which is included with Windows by default.
Edit: This article on MSDN should get you started in the right direction.
What you're talking about is C++/CLI, it's microsoft's dialect of C++ that requires a .Net framework. Please distinguish it from real (native) C++, which can be used to create what you want to. Visual C++ is perfectly fine, just make sure you don't create a .Net project.
Forms are a .NET library. It's not Windows or anything like that, you can use the native GUI libraries in Win32 with no problem or any native wrapping of them. You can implement this in native C++ easily in Visual Studio.
If you're looking to create the application in a rapid fashion (i.e. stock UI components that you can drag and drop onto forms), my experience is that Embarcardero C++ Builder effectively solves that problem space.
I like Visual C++ but it's not a great environment for rapidly creating forms based applications. I want to emphasize that I'm referring to Rapid Application Development (RAD) tools. There are plenty of great C++ IDEs and libraries for creating forms based applications and all of them should be able to create standalone exes.

Best C++ IDE or Editor for Windows
I am working on a database project that requires me to code in C++. I have the framework for the relational database built using Microsoft Access. Since I would like a GUI for the user, I am trying to use Visual C++ 2008 to build it.
I have tried to build a solution as a win32 console app, MFC app, and CLR app, each halting me with their various errors.
I have scoured the web for help but to no avail. If anyone could give me some direction or, better yet, a link to a good tutorial, it would be much appreciated.

I found an MSDN article about developing C / C++ apps that connect to Microsoft Access. Hope this helps.
