Programmatically browse workspace

[MichaelAivaliotis]

From my LabVIEW UI I have to always do a File>Browse Workspace...
I do this because I normaly use a workspace file with the TS UI so all my paths (code modules and sequences) are relative to this workspace.

Is there a way to programmatically browse to or load a workspace file?

Hi Michael,

I would use an expression step with 'RunState.Engine.DisplayWorkspaceBrowserDialog("",0)' as the value for the expression field.

This will accomplish the same function and clicking File»Browse Workspace... in your OI.

Thank you. However is it possible to specify a file path to the workspace so that you don't require the user to perform a browse?

[Evan P.]

Absolutely; try RunState.Engine.OpenWorkspaceFile("<your project folder path>\\<your workspace>.tsw",0,1). The 0 and 1 correspond to the default options for this function.
This should obsolete the need for the previous function that I mentioned, since opening the dialog is not necessary when we open the workspace directly.

Ensure that you execute this expression before you open your sequence file, so that the paths are relative to the correct locations.

Thanks!

Hmm, I'm trying this but for some reason it does not have  the effect i want. See image.






Even after I execute this code, the workspace is show as not loaded.

Engine.OpenWorkspaceFile() reuturns a reference to the WorkspaceFile object. Setting Engine.CurrentWorkspaceFile to reference this WorkspaceFile will accomplish what you are wanting.

So, continuing with our expression example from earlier, our expression value wold be:

RunState.Engine.CurrentWorkspaceFile =  RunState.Engine.OpenWorkspaceFile("<your project folder absolute path>\\<your workspace>.tsw",0,1)

In your LabVIEW example, adding a property node for the CurrentWorkspaceFile is necessary as wellas ensuring that you close the OpenWorkspaceFile reference after you feed it to  this property node. (This would not be necessary if compiled in TestStand, since TestStand would automatically clean-up this object reference)

Ok, perfect. I made this change and now it's working properly. Thank You.
