Audio Hardware - Read All The Labels Integer As The Sound Of Midi - Controls Selection On Vb 2005

I want to build a system that will take the input from an electric guitar and capture the frequency of the sound. and when the frequency is captured, the system identify the chord, and create new controls to represent the audio frequency. i want to use the label as the controls. so when the controls is created, how can i know that the user is click on what label. is there something like label1.click in vb 2005 express? then when the label is all created, i want the system to read all the labels integer as the sound of midi. so i have to assign what integer for what sound.
