Request: UDP Command to Clear Message Log

a UDP command to Clear the Message Log would be great, this way the user could clear the log after unlocking/re-allowing DLLs.. which is often desired behaviour when using new builds of DLLs.

if the command could also avoid popping up the dialog with the latest news in it, that usually appears when manually clearing the log (if it hasn't been checked), that would be great

We are not doing any further development with the UDP interface. We can add this function to ACSIL.

Actually this function does already exist in ACSIL:
sc.ClearMessageLog()

ah great, I didn't know about that.

I understand you aren't enhancing UDP anymore.. but please don't remove it. I find it very useful to easily unlock and allow DLLs again using powershell scripts

do you have a list anywhere of new functions which get added to ACSIL? at least the more important ones?

do you have any hints about when it would be a good time to call sc.ClearMessageLog() ? the main reason i was asking for it for UDP was because when building new DLLs it was a logical time to clear the logs.

I would think a good time would be upon starting recalc but the problem there is that sometimes Sierra can restart a recalc and then it is important to actually see the log, so clearing upon a single full recalc starting is a good idea but if there will be multiple recalcs it is a bad idea, and it is not always predictable if there will be multiple recalcs..

There is no specific place where we list "new" functions/variables. We try to keep the documentation updated with changes, but we typically are several months behind with the ACSIL documentation, so new items can be added that would not be specifically noted anywhere.

The best thing to do is to look at the sierrachart.h file in your ACS_Source folder and note the "SC_DLL_VERSION" at the top. When this changes, then something has been added.

Items that are added are at the end of the file.
