Programming Howto:Attach the Debugger to a BCI2000 Module
Duplicate a SignalGenerator batch file from the BCI2000 batch directory that is similar to your needs
Rename it to contain "VeryNiceSignalProcessing" in its name
Edit the batch file by adding --EvaluateTiming=0 to the SignalGenerator line, and by replacing the signal processing module's name with "VeryNiceSignalProcessing"
Double-click the batch file to start up BCI2000
In the VisualStudio IDE, set a breakpoint in VeryNiceFilter::StartRun(), and choose "Attach to Process..." from the "Debug" menu
From the process list, choose "Very Nice Signal Processing", and click "Attach"
In the Operator window, click "Set Config" ...
... and "Run", which will execute VeryNiceFilter::StartRun() ...
and cause the debugger to stop execution at the breakpoint you set earlier
