Loading Fp in background

[ITA]

Hi,

I am wishing to develop a menu driven Main.vi, which shall call several other programs, say A, B, C, D. The algorithm for all these Vis should run in background, while the front panel of only that vi (one at a time) whichever is called from menu of Main.vi should be visible to user, removing other FPs from memory.

The way I am doing this is attached here. I am not sure whether I am doing it correctly.....Or are there any better ways to achieve this?

Second problem I am facing is when A is open and I try to open B from Main.vi then; A is going backward. I have tried with subpanel option, but in that case close Fp option is not working........can any one suggest ways to solve this problem? You may modify and repost my code (Ver. 7.1 if not then .jpg )

Please rename the attached file to .rar and then extract if .zip is not working.

Thanks!

You're mixing and matching two different concepts: static loading and dynamic loading. It's not clear which one you're trying to do, but I'm guessing dynamic loading. In that case you should not have the "A", "B", etc. VIs on the block diagram of the main VI. Doing so causes them to "run" as soon as the main VI starts.

Suggestions:

• Look into using the event structure rather than a polling scheme.
• Instead of using a string for your "Action" use an enum. 
• Be careful about the Current VI's Path function. If you build your VI into an application the path that gets returned will have the application name appended to it.

Hi Smercurio, 

THanks for your suggesions.

In fact I want to have a dynamic loading scenario. But when I used it, I was getting errors from property node and was not able to do Open Fp and Close Fp functions.

So the code I have posted reflects static loading only. Could you/ anyone be in position to modify attched code for dynamic loading ?

Thanks !

Hello!

My suggestion about menu application using VI Server may be interesting for you:

What errors? What were the error codes?

No, what you posted was a combination of static and dynamic loading. That's the problem.
