Hi there

I'm completly new in plug-in programming.
The first project in the book "Desining Audio Effect Plug-Ins in C++", calles "Volume" i get an issue I'don't realy get.
It compiles the code generates it and then boom Cpp files already has a Functionbody ( translatet from german so maybe not 100 % accurate)

So I followed the instructions of the book and the code seems not to be a problem.

I use VB 2015 Community on Win 8.1 64 bit system.
The VB Cpp file is empty though there is a textfile which has code written in it.
I can open the Cpp textfile with VB but I get the same error while compiling

Any suggestions what I'm supposed to do?

Hi D-p,

I can't really follow your description. Did you create the project with RackAFX or did you download a project from the website?
What do you mean by "Cpp textfile" and "VB Cpp" file?

Usually, RackAFX should start Visual Studio with the generated C++ project. This should just build fine.

You mention "VB" several times - what are you referring to? Did you install the correct Visual Studio version?

Hi Tom

I solved the problem. VB is Visual Basic. RackAFX creates an .h and a .cpp file for each project. Normaly you write your code
into the "name of the project".cpp file. By accident I modified the .h file instead.

This could never work.
I opened the .cpp file with the texteditor by accident and Windows saved it that way. Because of that
VB didn't opened the .cpp file and I started the .h file manualy.

Now everything is running fine^^

Best regards
