How to delete only a portion of the data portal?

[james brunner]

This would be similar to DataDelAll() command, but allow only a limited set of data to be removed.

For some background:

- DIAdem 9.1 sp2
- LabVIEW interface calling various DIAdem/VBS scripts

Using DIAdem to format reports based on various scripts and TDM data results, I would like to be able to load and unload various data files (TDM) while maintaining the specific report layout (also TDM) data in the portal.  Two (ugly) options seem to be:

a)  load entire data result set into the portal (including layout instructions) and process, or
b)  keep track of layout state variables and clear portal/reload layout/load next data

This would all be easy if there is a command to enable the right-click delete... behavior of the data portal UI.

Thanks!

Hello James,

there are diufferent commands you can use to delete only a portion of the data in the portal. You can delete single channels, a selection of channels, or entire groups with these three commands:

Call ChnDel(ChnArg) - deletes one channel
Call ChnDelete(ClpSource) - deletes a selection of channels
Call ChnSDel(ChnArg1, ChnNo) - delets a number of channels
Call GroupDel(TargetGroupIndex) - deletes a group including its channels

To create a selection of channels as argument for the second command, have a look at the functions

ChnSelAdd, ChnSelGet, ChnSelCount
