I've been having trouble controlling the CoffeeCup webcam program using powerhome.  The switch app works fine, and most key transmissions via sendkeys work fine, but not all.  I can manually type an alt-s to get a desired effect, but an {alt-s} in the sendkeys has no effect.  The same key {alt-s} works in other contexts though.  I'm using powerhome 1.03.4.  Thoughts?

Chris,

It may just be a typo in your post but the proper format for sending an alt-s is: {alt+s}

Sometimes the sendkeys can be tricky to setup.  When setting these up, I usually take it one step at a time.  I'll have PowerHome simply switch to the application.  I'll then use the keyboard to test the next keystroke combination to verify that it's what I want.  I'll code that into PowerHome and then start from the beginning and let PowerHome switch to the app and send the sequence of keystrokes that I have so far.  Sometimes, I find that I need to place a small delay within the keystrokes or I might need to send an 'escape' or a 'tab'.  Basically, whatever you can type on the keyboard should be able to replicated using sendkeys.

I use Webcam32 software with my ATI All-in-Wonder video cards tuner as the source (I have different video cameras modulated onto a single coax) and I have to change the channel in order to view different cameras.  The following is a sample of the sendkeys code that I have to send to do this:

"{alt+f}p{downarrow}{downarrow}{downarrow}{downarrow}{rightarrow}s{tab}{enter}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{tab}{uparrow}{alt+a}48{enter}{tab}{tab}{enter}{tab}{enter}"

Hope this helps,

Dave.
