Channel write protection - still there after using ChnValExpand

[mrme]

Hi,

When I load certain datafiles, some time channels appear as write protected.  I use ChnValExpand which appears to work (the little symbol disappears from the channel name).  However, the channels remain protected and I am unable to write to them.  How can I remove the write protection? 

Any help is appreciated

Thanks

Thomas

Hi Thomas,

It seems that this is a bug. If you some similar code like this below, the you get an error regarding write protection:

dim oChn
set oChn = Data.Root.ChannelGroups(1).Channels(1)
call ChnValExpand(oChn)
oChn(1) = 5

The workaround is to redefine the object variable oChn like this:

dim oChn
set oChn = Data.Root.ChannelGroups(1).Channels(1)
call ChnValExpand(oChn)
set oChn = Data.Root.ChannelGroups(1).Channels(1)
oChn(1) = 5

The all is fine.
