Programmat​ically Inserting search directory

Question

Hi Ppl,
I tried programmatically inserting a search directory. I used the method Engine.SearchDirectory.Insert. After calling this method I called the SearchDirectory.Reload method. Despite calling this method the newly added directory was not displayed in the search directories list in sequence editor. When we change Mytypes.ini or other configurations external to sequence editor I get the pop up to reload them. But when I inserted search directory It didnt ask for reloading. I had to restart sequence editor for the new directory to be listed. How do I reload without restarting sequence editor ?
Below is the code that I used .
Solved!

Sathish -
I believe the behavior you are seeing is expected. When you call the VI stand-alone outside of TestStand, you are creating a different instance of the engine. Thus, you have one instance of the TestStand Engine in the Sequence Editor process, and one instance of the TestStand Engine in the LabVIEW process.
Now, when you call SearchDirectories.Reload() from the LabVIEW VI, you are telling the LabVIEW instance of the TestStand Engine to reload the SearchDirectories that it has cached from the SearchDirectories on disk, however, this has no effect on the Sequence Editor instance of the TestStand Engine.
Now, if you were to call your VI as a code module from a sequence that you execute within the Sequence Editor, and you pass the Engine as an input to the VI (RunState.Engine), then you would see the behavior you are expecting.
You could also try the following as a test: With the Sequence Editor open, run your VI as you have been. Then, in the Sequence Editor, execute a step that calls RunState.Engine.SearchDirectories.Reload() (if you're in TestStand 4.0 or newer, you can simply call this in a Statement step). Then check the Search Directories... have they updated?
Hope this helps.
