Accessing Global Data in Express VI's

[VRMan]

Hi,

I am trying to access global data shared between regular VI's and Express VI's. However, Global Variables and Functional Globals that are added to both VI's don't access the same global data. Were Global Variables and Functional Globals the correct approach? Or is there another special approach needed because of the Express VI Toolkit?

Thanks in advance for any help.

Hi VRMan,

I do not think it's possible to use Global Variables or Functional Globals in custom Express VIs. Is there a reason why you might want to use global variables/functional global in Express VI that you've created? Perhaps you want to try just passing data to the Express VI through the connector block.

Well, the Express VI configuration VI's appear to be executed during deisgn time instead of run time of the VI that's being edited, so I don't really see how I can pass data between them through regular connector blocks. I have implemented a temporary workaround using an external file.
