Sequence not released (even nothing open) using API

[gavin.gqchen]

Hi, I try to using Labview(8.6) to make a UI to call teststand engine.

Currently I only do the following steps:

- start the engine

- enable the "UIMessagePolling"

- Login

-shutdown engine(false)

- Logout

-shutdown engine(true)

However, there are always some message saying some sequence not released, here is the message:

The Engine.ReleaseSequenceFile(Ex) method was not called for the following files:
    C:\Program Files\National Instruments\TestStand 4.0\Components\NI\Callbacks\FrontEnd\FrontEndCallbacks.Seq
    C:\Program Files\National Instruments\TestStand 4.0\Components\NI\Callbacks\Station\StationCallbacks.Seq
    C:\Program Files\National Instruments\TestStand 4.0\Components\User\Callbacks\Station\StationCallbacks.Seq

I don't know why because I even did not start loading any sequence, any one can help me?

Hi,

Some sequencies are used to achieve particular functionality. For example, the FrontEndCallbacks.seq file contains sequence files that TestStand can call from user interfaces. So you may need these sequencies even they are not explicitly called.

The login/logout callback is implemented with an execution. Perhaps your UI message handling is leaving these around? Are you using the ApplicationMgr control? You might want to start with the example code for the LabVIEW full-featured or simple UI that ships with TestStand or take a look at that code and see what you are doing differently.

Hope this helps,
