Close one vi and open another

[sujeep]

Hi

Is it possible to open another vi when I click a button and close the current vi.

thanks

Sure, all you have to do is:

1. From the current VI, open a VI reference to the new VI
2. Run it using the Run VI method (be sure to wire a "false" to the Wait until Done input)
   
3. Open its front panel using the Front Panel: Open method
4. Close the current VI's reference to the new VI
5. Close the current VI's front panel using the Front Panel:Close method
6. Stop the current VI
   

Be sure to do steps 2 and 3 in the order shown here - it looks better.

Hi sujeep,

what about using 2 subvis connected by good dataflow (error cluster?!) to ensure sequential processing?

Hi Mr. Mike

Cn u explain me about the reference to vi. Where do I kind that.

Also can I get the values that I enter in the first vi to the second vi other than to store in a file and then retrive in the second vi.  

thanks in advance.

Hi sujeep,

again: why not use subvis with proper dataflow?
See this codesnippet:

the first vi is getting some data, after closing the vi the next vi is started and gets the data from the first one...

Thanks a lot  I got the concept.

Here, try this. Enter the path to the VI you want to launch and run the program. When you press the button, the VI you specified will be launched and the program will be closed.

Thanks Mike - excellent instructions.

Thought I'd include a screenshot of your code in my application.
