How to remote control volume

[richardgray]

Hi I was wondering if someone can help me.

I want to be able to control the volume of a remote PC.

I want to be able to read the current volume level, then adjust the volume via a slider to set the remote volume level.

I have see the posts

for the adjusting the remote volume and

for the slider.

I may be able to link the two together but would really like to be able to have a starting value.

Thanks

Richard

Wilt the help of using code supplied on the forums I have managed to get something to work, and I'm sure people will be able to tell me all I've done wrong

I used the simple TCP from matwachich, some of the audio from wraithdu (or I was going to if my server wasn't running XP) and the slider from elseware on the site, and I just cobbled them together.

This is the client side
