switcherlib.dll Preview

Hello,
I try a program in c# using the switcherlib.dll.
I want to store the preview number and than set an new input for transition.

My code:
MixerEffect meinMixerEffekt = new MixerEffect();

long previewnumber = meinMixerEffekt.Preview;
but
the error is: System.NullReferenceException

Where is my mistake?

Thank you
Jens

Where did you get switcherlib.dll from?

Hello Ian,

it´s the version 7.3.6.0 by Morrsoft (yours).

Other things like dsk, inputs, mediaplayer, aux etc work correctly.
I think preview is a member of MixerEffect. (SwitcherLib.MixerEffect.Preview) or is it the false class?

Thanks Jens

Hi, bmd intruduced some new input types for the mini which breaks my code (my fault for the way I was detecting the input type).
There is a new version of switcher lib (and some of my apps that use it).
