How to call a channel length in a calculation instead of a fixed value

[petros127]

Hi there,

I am fairly new to DIAdem scripting and I know this is probably fairly basic but I cant get it to work. 

I am trying run a calculation but firstly I am creating a channel which is a copy of another channel:

Call Data.Root.ChannelGroups(1).Channels.Add("NaN",DataTypeString,11)
Call DataBlClpCopy("[1]/esc_index",1,19191)
Call DataBlClpPaste("[1]/NaN",1,0,1)
Data.Root.ChannelGroups(1).Channels("esc_index1").Name = "NaN"

While doing this by recording, it automatically detects the length of "esc_index" channel to be '19191' but I want this to work for different sized files not just this specific one.

Also as an additional question, when I create the NaN channel, and copy the values from esc_index to it, it automatically renames the channel to "esc_index1", so I have to run another line just to rename it back, is there a way to avoid this?

Hello petros127,

This script code answers both questions:

dim oChnNew, oChnSource
set oChnSource = Data.Root.ChannelGroups(1).Channels("esc_index")
set oChnNew    = Data.Root.ChannelGroups(1).Channels.Add("NaN", DataTypeString, 11)
call oChnNew.SetValuesBlock(oChnSource.GetValuesBlock)
