Control devices with scripting

[donstephens]

I'm using Ed's tenScriptAid to write a script to control multiple devices. I have virtual devices to handle security stuff and I need to change them at Sleep and Wake.
Ed uses a boolean in his examples like this.

Dim rc As Boolean
rc = hs4.SendControlForFeatureByValue(28, 0) 

Probably a stupid question by what is the best way to deal with the boolean, declare it and then force it to 'nothing' after the hs4.SendControlForFeatureByValue statement or
just skip the boolean declaration and use the hs4.SendControlForFeatureByValue command. I'm trying to change four or five different devices and would like to not have to declare
four or five seperate booleans.

Thanks

rc only contains the return code of the function (worked or it didn't work). As the call is a function call and not a subroutine call, functions always return a return code.

You can reuse rc as much as you'd like.

Might want to actually check that the call was successful. Something like

If Not hs4.SendControlForFeatureByValue(28, 0) then
   hs.Writelog.........call failed,etc.
   Endif

Don't even need to declare a variable for the result

Yeah, great idea. Worked great. Thanks.

From my experience I always prefer local declaration for two reasons: if rc is declared somewhere else, later looking at your code you will be wondering what's rc? And if later you decide to delete the beginning of your code (which includes the declaration, or you want to rename rc) - suddenly you get the "undefined variables" errors all over your code.
You can simply define inline i.e.

Dim rc = hs4.SendControlForFeatureByValue(28, 0)

But I agree with tenholde (post #4) - it's even better option
