Are Inherited Forms And/Or Inherited Controls possible in Managed C++
Hello everyone The question is actually pretty self explanatory but I will further clarify it. I am building a simple application to show a load [file] for 5 different types of [files].

P/Invoke or C++/CLI for wrapping a C library
Have a moderate size (40-odd function) C API that needs to be called from a C# project. The functions logically break up to form a few classes that will be API presented to the rest of the project. Are there any objective reasons to prefer P/Invoke or C++/CLI for the interoperability underneath that API, in terms of robustness, maintain...

C++/CLI HTTP Proxy problems...
Hi, I'm trying(very hard) to make a small HTTP Proxy server which I can use to save all communications to a file. Seeing as I dont really have any experience in the area, I used a class from codeproject.com and some associated code to get started (It was made in the old CLI syntax, so I converted it). I couldn't get it working, so I adde...

VS 2008 irritating copy constructor link dependency
Hi guys, I've run into the following annoying and seemingly incorrect behaviour in the Visual Studio 2008 C++ compiler: Suppose I have a class library - Car.lib - that uses a "Car" class, with a header called "Car.h": class Car { public: void Drive() { Accelerate(); } void Accelerate(); }; What I'm actual...
Is there any way to get Visual Studio 2008 to update .net style comments automatically?
I've been writing a lot of VC++ 2008 / CLI software recently and am using the C#/CLI style documentation: /// <summary> /// Function the does stuff /// </summary> /// <param name="someParam">Specifies some option</param> /// <returns>true if it worked</returns> bool DoStuff( bool someParam ); I find myself re-typing those blocks quite...
Exposing an ISO C++ class to C#

Dealing with Expression Blend's lack of support for C++/CLI projects
I have a WPF C# project that references a C++/CLI mixed mode project. I'm having trouble using the WPF project in Expression Blend 3. I'm new to Blend so perhaps this is obvious, but it won't display the xaml designer properly until it builds the project. In my case it complains that my custom commands are not "recognized or accessibl...
How to link C# and C++ assemblies into a single executable?
I have VS2008 solution containg a project that generates a C# executable that references a project that generates a dll containing both C++/CLI and unmanaged C++.

Passing an array argument from C# to a C++/CLI method
I know only very little about C++/CLI, but I have a simple problem that needs a solution. I have a C++/CLI class method that takes a byte-array as a parameter. The array is of a pre-determined length, and can be allocated in C# beforehand. The array is supposed to be filled with data by the C++/CLI method. How do I declare the method an...

Targeting .NET Framework 4.0
I just downloaded MSVS 2010 from university MSDN AA. The IDE itself is wonderful, I can't complain, but... I'm developing project that combines C#, C++/CLI and C++ (native core, cli bridge DLL and c# GUI). But the VS 2010 seems NOT TO support targeting .NET for C++/CLI projects unless VS 2008 is installed. Requiring both VS 2010 and 20...
