php calling a named pipe server ( developed in Visual Studio

[guidodebouver]

dear php collegues,

I have developed a windows based solution that communicate through named pipes.
Development was done using Visual Studio .NET 2012.
All works fine.

Now I want to open the named pipe from php. Unfortunately, despite all my tries, I cant open it. The named pipesserver ( developed in Visual Studio ) never sees the request coming in.

Anyone who could help ?? I am really desperate on this.

One thing I have observed is that the characters in php are 1 byte, whilst in Visual Studio they are 2 byte. maybe that is part of the problem ?
