How To Open a subVi by pressing an "open file button",

[HFZ]

I got this Readdatasubvi I want to run when I press a 'Open file' button in the main vi, Then  The sub vi runs and a open file menu opens to choose a file to read from and plot out to a graph. It is working but how can I see the readDataSub VI as an application wich are running parallel with the main VI. It only runs in the background, and I cant see the plottet data Why????? The sub vi has a graph for the plotted data! but it never shows up!

an example is attached..

I'll appreciate any suggestions .

The stars are ofcourse waiting!

Hi,

this is because the open/create..vi calls the "file dialog.vi" inside.
The file dialog.vi opens its frontpanel automatically.

If you want your vi to show its frontpanel do the following:
In Labview open your ReadDataSub.vi.
-> file -> vi properties
category: window appearance -> custom -> customize
check "show frontpanel when called"
check "close afterwars if originally closed" if you want to close the frontpanel after execution.

There is still another way to do this from software.

1. place a property node on the blockdiagramm the vi you want to open. (application control-> property node)

2. right click on the property node then

3. select class -> VI Server -> VI

4. change properties to write

5. select "Front panel Window -> open"

with this property you can handle if front panel opens or not.

Hi Rainer

Thaks for the Hint,  But I figured it out By playing with the application  controls and so. But i wonder if there are in the property node, function that can

Close the Sub vi,, with out closing the hole Main VI. With it.

Coz if I press the Openfile button to open the Sub VI, and don't select a file to read from, and press the cancel button of the appeared "open file" window, My main VI stops, how can I avoid that. I want example make an cancel button in the sub VI!!

Is it possible.??

Hi,

i tweaked you example.
I guess that's what you're looking for.

P.S.: I unchecked the "open frontpanel" in the vi properties. i open (close) the frontpanel using property nodes now.
