Logfilewrite

[Simon_Aldworth]

Hello,

For some unknown reason I am finding that I cannot write multiple items using LogFileWrite anymore. The following code is fine when writing the first four LogFileWrite lines, each with a single entry, but fails for all the multiple ones. Why is this?

Option Explicit  'Forces the explicit declaration of all the variables in a script.

Dim myGp, i

Set myGp = Data.Root.ChannelGroups(1)
For i = 1 to myGp.Channels.Count
logfilewrite myGp
logfilewrite myGp.Channels.Count
logfilewrite i
logfilewrite myGp.Channels(i).Name
logfilewrite myGp & ", " & myGp.Channels.Count
logfilewrite myGp & ", " & myGp.Channels.Count & ", " & i
logfilewrite myGp & ", " & myGp.Channels.Count & ", " & i & ", " & myGp.Channels(i).Name
logfilewrite i & ", " & myGp.Channels(i).Name
logfilewrite myGp.Channels.Count & ", " & i
Next 

Regards, Simon.

Hi Simon,

The issue you're running into here is that the LogFileWrite() command accepts only a string parameter.  Your "myGp" variable is an object variable, and you can't print an object variable in VBScript (you can in python).  You also can't concatenate a string to the end of an object variable.  Any command where you have this will throw an error:

logfilewrite myGp &

Oops, should have spotted that. Thanks Brad.
