How to create a subVi who outpouts its VIRef to connect to a supanel in mainVI

[Ub4thaan]

Hi all,

I've got a VI who got some inputs and output, and id' like to output also it's VIRef so i can connect it to a subpanel and diplay it when a button is pressed.

Can someone help me?

Example code in the image

Pallette >> Application Control >> VI Server Ref

Drop that on your block diagram.  From the drop down menu on that object, select "This VI".  Output that reference from your subVI and use it for the input to the insert invoke node.

I prefer to connect sub-VI Front Panels to the sub-Panel "in the forward direction", that is, get the Main (with the sub-Panel) "find" the sub-VI it is going to display, rather than have the sub-VI try to pass a reference to itself backwards to the caller.  I do this by using a Static VI Reference (on the Application Control palette), right-clicking it, and Browsing for the sub-VI.  If you have created an icon for the sub-VI, you'll get a nice "self-documenting" indication of what you are doing, like this:

This code is in the Main routine -- when it is executed, it will run the sub-VI right after placing the sub-VI's Front Panel in the Sub Panel.

I opted for Bob_Shor's solution, for now, becouse it's a bit more straight forward for a noob like me

Who is this Bob_Shor person?  Not only is my method straight-forward, but if you ever need to build an executable with this code, it will "automagically work".  I use a similar technique (using Static VI References) with working with "clones", routines started with "Start Asynchronous Call".
