You may need to deploy additional things used by your C++ code, like MFC and/or the CRT libraries.

You should also understand interop between native and managed code, if it applies.

Thanks for your reply.

I cared about if C++/CLI can be used in a large C++ project, are there any troubles may happen?

C++/CLI is great for making the transition from native C++ to the managed .NET
world - that's it's intended purpose. If you have C++ code and you want to use
the .NET framework then it's great.

Eventually you'll notice that the development tools using C# are much better, but
C++/CLI let's you use your existing C++ code as you make the transition.

I use C++/CLI extensively, along with native C++ and C#. There's no troubles that are any
different than using any other .NET language. Having the rich .NET framework available to
existing C++ code is great.

It's worth taking the time to study and understand the fundamentals of managed programming.
Especially important is performance-critical applications if you're making a lot of transitions
between managed and unmanaged code.

Why is BinaryWriter() is inserting unwanted bytes?

BuckBrown2-Jul-08 6:41

Hi, I'm using Visual Studio 2005 C++/CLI. I have a requirement that needs to write some ASCII to a file followed by binary data. I set up a BinaryWriter(FileStream) and everything is okay except that there is a byte preceding the String^ variables denoting the number of characters to follow. I do not want these "extra" bytes in the file. Is there a way to surpress these bytes from being written to the file?

Thanks,
Buck

You need to write the String chars yourself.

BinaryWriter has a Write() method that writes a Char.

for (int i = 0; i < str->Length; i++)
   writer->Write(str[i]);

Of course, you won't be able to read the data back in as a String
without some way of indicating where strings end in the file.

Install Visual Studio Redistributable, and you must click on properties of your project -> Configuration properties and Configuration change from DEBUG to RELEASE.
I must install .NET framework 3.5 to another computer. It is working on Vista, under XP It dont works.

You have been a member long enough to know that's wrong, what a jerk.

Also, are you planning on ever learning how to research, study and learn on your own or are you planning on asking anonymous people on internet forums for all your information for the rest of your career, however short that may be?

Can some one please point to a sample CLR project developed using VC++ .net 3.5 framework. Or a book which describes on creating projects in vs 2008.
Thanks

Everything you need to know is this (for VS 2008):

File -> New -> Project then look for Windows Form Application

click to Form1.h, you can see Form1.h [Design] and you can place some components from Toolbox there. In Properties are the characters of components.

Well I have not installed VS2008 yet but VS2005 and all the way back to like VC6 came with samples in the Installation. Take a look in your Programs Files/<VS install folder> etc., they may already be there, if not run the Installer and look for Samples as an option and install them.

Here's my short book on creating a CLR project in VS2008:

1) Start VS
2) From the file menu, choose New/Project...
3) In the New Project dialog, select .NET Framework 3.5 with the drop-button on the upper right.
4) Select Visual C++/CLR in the Project Types tree
5) Select a template in the Templates list
6) Give the project a name and location in the appropriate dialog fields, creating a solution if necessary
7) Click OK
8) Open the solution explorer window (View menu/Solution Explorer)
9) Right click the new project in the solution explorer and click Rebuild

You should now have a working sample CLR project developed using VC++ .net 3.5 framework.
