Howto efficiently Copy array into data portal

[TCPlomp]

I have an array in VBS memory and would like to create an channel in the data-portal based on that data-set, I currently use this code construct to copy the data:

---

' intChannelCount is the number of samples

'MaxHold is the data array to be copied

'oFFTMaxHold is the data channel that is the target of the data

for counter = 1 to intChannelCount
      oFFTMaxHold.Values(counter)=MaxHold(counter)
next

---

 It is rather slow (and if the data preview is open in the data portal) even much slower.

Is there a method to copy the whole array in one operation to a channel?

Hi Ton,

If you have DIAdem 10.2 or later you can use the following command to do this with one command-- passing the array of values as one of the command's parameters-- this is a common situation when querying records from a data base that you want to load into the Data Portal as channels.

ChanRefsArray = ArrayToChannels(ValuesArray, ChanNamesArray)

In the case of your example below, that would be:

Call ArrayToChannels(MaxHold, Array(oFFTMaxHold.Name))
