Hello Experts,

Can someone please tell me how to fix the Type Mismatch error at line 168?

Hi Sedgwick,

I'm not entirely sure I know what you mean?

Actually, the script is the one you helped me create. I'm trying to tweak it so that I can run a different of commands when I different trigger occurs.

If you remember, the trigger 'changed state to down' would execute a number of commands. I'm trying to tweak the script so that a different set of commands would be triggered if ,say a statement appeared on a device that I was connected to said 'elvis is alive'.

Would you like to see the original script as a recap?

Cheers

each index in g_vCommands reflect a command.
so when the error occur, what is the value of nIndex?
does it happen in the first entry to the loop when nIndex = 0?

replace this line:
 szCommand = Trim(g_vCommands(nIndex))

Open in new window

with this line:
dim nextCmd 
nextCmd = g_vCommands(nIndex)
wscrip.echo nIndex & " " &nextCmd
 szCommand = Trim(nextCmd)

Open in new window

what is the output to the screen?

Hello Sedgwick,

Sorry for the delayed response - I had to run into office.

Anyway, I'm getting the error shown in the attachment.

now i understand, you declared the g_vCommands inside other sub, so it is not accessible to other subs
u need to declare it globally.
if u look at the script i posted, i moved the g_vCommands  declaration outside any sub (above Sub Main).
now it can be read by any sub in the script:

Hi Sedgwick,

I'm not sure how the script will run a different set of commands if say instead of 'changed state to down' was echo'd back 'elvis is alive' echo'd back?

Cheers

OK, Sedgwick, this is looking good.

So, what if I wanted to change the array/variable/parameter to send the commands if the message 'elvis is alive' (of course I'm being silly with the elvis thing, just want to emphasise to point).

I would like another set of commands to be executed.

If you just give me a guide on how it can be accomplished I'll try and do it myself - I just mindful that you've helped me sooooooo much and I appreciate it mate.

i'd use external file which lists all commands and have the vb script read them and loop them, so you won't need to change the script in case new/different commands are required.
