Hello

I have an error when I use DSP_PeakLevelMeter with bassAsioHandler.InputChannel in an WPF application

Please clarify what the problem/error is. If a function call is failing, which function is that and what is the error code?

When you are in WPF, it's not possible tu set  " progressBar1.Value ". it's necessary to use an Invoke fonction

Error Message is : "Created by an over thread"


No problème in a Winform app

Try this code (C# WPF)


Dispatcher.Invoke(DispatcherPriority.Background, (Action)delegate()
{
        //Do your stuff here (that is GUI controls)... Ex:
        progressBar1.Value  = MyValue
});
