I just wrote a very simple wrapper for the PayFlow Pro SDK (see below).
A friend of mine did this before, but I didn't have access to his
source, so I took it as a learning opportunity for me to write a C
wrapper. I did a little searching to see whether anyone had done
anything like this for Python. I didn't find anything.
I did find that PHP comes with an extension for PayFlow Pro that you can
compile into the language:

Hi
Ive been using Mattias Sjögren's example at
http://www.msjogren.net/dotnet/eng/samples/dotnet_dynpinvoke.asp to load an
unmanaged 3rd party dll dynamically when my object is created. Calling the
"CreateDllAssembly" function below does this.
When my wrapper is disposed of, I want the dll to be unloaded from memory.
See the "dispose" function below.
All seems to work ok on the first instance of my wrapper class. (I only

I've found some rather worrying articles (Mixed Mode Library Assembly bug,
Richard Grimes, Windows Developer Network Sept 2003 ; and Knowledge Base
Article 814472 ) that point out the need to use the /noentry switch and an
explicit initialisation procedure, to be able to safely use Managed C++
assemblies that call down into standard C library functions.
Could someone confirm that I've understood this properly ? I'm writing some

I have an unmanaged C++ library that I need to use through C#. I created a
Managed C++ class library and through it wrote a wrapper class to call what
I need.
However, one of the methods (an Initialize function in the unmanaged
library) crashes everytime I call it. Initialize calls another function
'GetInstance' (a static member function of a class) which looks something
like:
CLibConfig& CLibConfig::GetInstance()

How does the lambda library actually works. How does it know how to
evaluate _1, how does it recognize _1 as a placeholder, how does it
then calculate _1+_2, or _1+2 etc. The source files seem a bit
complicated so any explanation would be appreciated.
Thanks

While my question doesn't pertain specifically to python programming,
it is a result of developing a python module, so I'm hoping someone
here might have experience with this issue.
So, first a little background to how the system works right now. I am
developing a module for Python. The original code is written in C++ and
I am creating a wrapper using Boost.Python. The C++ code for the module
makes calls into a library that in turn...

Hi,
I have a statically-linked C library (.lib) that I need to be able to
access from C#. I understand that the best way to do this is to code
a C++ managed wrapper.
How do I create this wrapper? One of the functions in this library is
as follows:

I have project that uses managed c++ where I use c - library, this library
contains some variables named generic, during compilation I get error: Error
1 error C2146: syntax error : missing ';' before identifier 'generic',
Problem is that in dotNet generic is a keyword, and I cannot change this
name becouse I have only lib file and includes.
How to solve this problem?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
