Converting an unmanaged C++ project to be managed

[Rob C]

Are there any good papers/documentation around for taking
an unmanaged VC++ Project using MFC (created in VC V6) and
making it managed? My main goal here to be able to
implement new functionality in our system using C# and
being able to utilize the C# assembly from within the
existing VC++ code.

Can you mix and match like this? For example, could I
have CObject derived object create a C# assembly that
creates an OLE DB recordset and stores properties into the
CObject-derived object?

Thanks for your help.

It's just a matter of using /clr switch and you get access to your C#
assembly and MC++ syntax.

Yes

Thanks for your response.

I looked at the document and it states to set the /clr
option. When I do this I get a build error:
"cl : Command line error D2016 : '/RTC1' and '/clr'
command-line options are incompatible"

I can't seem to find which setting to uncheck to disable
this setting.

Also, once I do this, what will I have to distribute with
my app for the .NET runtime?

/RTC1 is "Basic runtime checks" setting under Code Generation.

You either have to direct users to windows update site to get .net redist
or

Under Project Properties/Code Generation, it does not let
me deselect this option. The possible values
are "default", "Stack Frames (/RTCs)", "Uninitialized
Variables (/RTCu)" and "Both (/RTC1, equiv. to /RTCsu)".
All of these selections generate that same error. Is
there a different porperty to set that turns off this
option?

It actually was set to default to begin with the first
time I got the error. I tried selecting each one and
rebuilding but to no avail.

Any other thoughts?

Thanks again for your help.

Don't know. If this was vc6 project converted to VS.NET then maybe
conversion failed somewhere.

This is strange... I was able to build the project as a
Release Build with the setting set to default but I still
get the error when I try to build it in Debug.

I guess its time to cash in one of my support incidents at
Microsoft.

Thanks again for your help.

No just do this:
Open .vcproj file from your project's directory. It's in xml format.
Find
<Configuration Name="Debug.... >
<Tool ... BasicRuntimeChecks="3" ... />

Change it to 0.
