References to PropertyObjects were not released properly.

[IVI]

Hi,

I am getting the following Error on closing the TESTSTAND. 

References to PropertyObjects were not released properly.
    Total number of objects: 65570
    Number of top-level objects: 199

    Note: Some top-level objects may be included if they are referenced by
    an incorrectly released top-level object. For example, an unreleased
    SequenceContext object references a SequenceFile object.

    The following top-level objects were not released:

        SequenceContexts [3 object(s) not released]
            SequenceContext #1:
                The context last executed sequence 'Configure UUT Information' in file 'Common_ATE_SequentialModel.seq'. 

            SequenceContext #2:
                The context last executed sequence 'PreUUT' in file 'Common_ATE_SequentialModel.seq'. 

            SequenceContext #3:
                The context last executed sequence 'Test UUTs' in file 'Common_ATE_SequentialModel.seq'. 

        Files [1 object(s) not released]
            SequenceFile #1:
                Path: D:\Honeywell\CommonATE\TED\Framework 3.0\CommonATEModels\Common_ATE_SequentialModel.seq

        Sequences [3 object(s) not released]
            Sequence #1:
                Name: Configure UUT Information

            Sequence #2:
                Name: PreUUT

            Sequence #3:
                Name: Test UUTs

        Type Definitions [47 object(s) not released]
            Type Definition #1:
                Name: ModelOptions

            Type Definition #2:
                Name: NI_StationInfo

            Type Definition #3:
                Name: DatabaseOptions

            Type Definition #4:
                Name: NI_DatabaseOptionsSchema

            Type Definition #5:
                Name: NI_DatabaseOptionsStatement

            Type Definition #6:
                Name: NI_DatabaseOptionsColumn

How to release the resources used?

Am using some GUI's created in .Net Internally i doubt it creates the problem?

Help me in identifying this problem

Thanks in advance

Does your GUI open or use any references to your execution? The debug reports show you're not releasing three sequence contexts from your process model.

Most likely it is the GUI that is not releasing things. If any TestStand objects aren't released before the TestStand Engine is destroyed then they are reported as leaks. .NET complicates things because it releases references only when garbage collection occurs. Look at our example C# UI for places in which GC.Collect() is done. Also if you get a sequence file using Engine.GetSequenceFile[Ex](), you need to make sure you release it when you are done with it using Engine.ReleaseSequenceFileEx.

Hope this helps,
