I wrote this code in c# and the issue here is that when I run the program the form window will not show up because of this line: RecognitionResult result = recEngine.Recognize();
But when I comment it out the code runs I also commented out the switch cases because they use the e.result..
My main goal with this code is to change the Grammar whenever I say the keyword so do you have a better way solving this ?
Thank you!

@Crowcoder, @Hans Passant thank you for the help. I managed to solve the issue by getting the grammars from a class.
