Select channels programatically?

[Julia Dawkins]

Hello,

I developed a little script to search through the channel names in the data portal.  Entering the beginning or partial name of a channel gives a list of all channels that match.  After they find the channel(s) they are looking for, I have given them the option to put these channels in a graph or table in REPORT or VIEW.  I thought it would be neat to also give the option to "select" the channels in the data portal, so they could do what they would like with them.  I cannot seem to find if I can do this programatically though. 

Thank you!

Hi Julia:

You would have to use the ChnGet function to access Channels in the data portal programatically. The format for this function is
Call ChnGet(ChnSingleNo, ChnMultiNo, ChnGetTitle)

Thank you

I have created a Community Example Program which may be of your interest: it performs a filtered group and channel search using dialog.

Hello Julia,

can you explain why it was necessary to develop a script instead of using the built-in filtering from the Data-Portal ?

Thanks for explaining.

Hi Julia,

Did you find the programmatic channel selection function for the Data Portal?  All programming in the Data Portal these days starts with the "Portal" object.
