Open sequence method anywhere?

Question

Hello,
I'm making a edit substep using labview for a step type, which will open a teststand sequence in the editor.  There already is an item "open sequence", but this particular step type executes a sequence by expression at runtime, so we can't open at edit time using the "open sequence" item.  The substep will prompt the user for the necessary information to find the right sequence, but then I want to call a method to open the sequence in teststand, in the same way as "open sequence" works when you right click on a sequence call. 
I have browsed the methods/properties for "sequence context/engine", and I see an "open workspace file" item, but we are not using workspaces (which is a completely different post).
So can anyone tell me where there might exist an "open sequence" method with which I can open a teststand sequence in the editor?
Thanks
David Jenkinson

Hey David,
I'm not sure this is possible unless you have a custom seq. editor or you do it in the UI.  That is if I understand you correctly.  Basically you want to dynamically load a sequence file into the seq. editor?  Is that correct?  If so you can load it into memory just not have it show in the seq. editor. 
GetSequenceFileEx Method
Syntax
Engine.GetSequenceFileEx ( sequenceFilePath, getSeqFileFlags = GetSeqFile_OperatorInterfaceFlags, handlerType = ConflictHandler_Error)
Return Value
SequenceFile
A SequenceFile object.
Purpose
Returns the SequenceFile object for the sequence file specified by the sequenceFilePath parameter.
Remarks
Loads the sequence file from disk, if necessary. Call ReleaseSequenceFileEx on this object before releasing it.
This method loads the sequence file into the engine's internal cache and adds a load reference to the sequence file. TestStand uses the load reference count to determine when to unload the sequence file from the engine's internal cache. In addition to this method, the SequenceFile.AddLoadReference and Engine.NewSequenceFile methods also add a load reference to the sequence file. The Engine.ReleaseSequenceFileEx method removes a load reference.
You must call Engine.ReleaseSequenceFileEx for each load reference that you add to the sequence file. When you release the last load reference, TestStand unloads the file from the engine's internal cache. While unloading the file from the cache, TestStand executes the SequenceFileUnload callback, if applicable.
You can use SequenceAdapter.GetSequenceFile to examine the contents of a sequence file without running load and unload callbacks, without preloading modules, and without merging types.
Hope that helps,
