How can I stop a VI-DLL programmatically?

[Dedel]

I load a Labview-DLL into a subpanel with the Call Library Function Node. I can quit this DLL (fitted with an event structure) easily with a button on it's front panel. But how can I terminate this DLL programatically from outside? From the calling VI? From another VI? Thanks for a hint. Dedel

hi

you can quit the DLL( you mean the source code used in it?) using a control? the source code has an event structure?


do this:
call this DLL in a blank vi. Use only the call Library function node and required controls and indicators to the DLL.

Try stopping it. Get back with the result.

P.S: event structure does not let you control the source code of a DLL.

where is this control that terminates the DLL?
in the vi using subpanel? or in the source code?
 

explain your question a little more... please!

I have attached my test scenario. A simple VI calls the DLL and places it's front panel on top of it. The DLL handles events and finishes by 'value change' of the stop button - as usual. The idea behind this all is to have a main panel with some sub panels. The sub panels are filled with exchangeble DLL-VI panels (plug-in's). These panels (DLL-VIs) are invoked from selectors on the main panel and must be released if exchanged.

hi

i am not sure i will be able to answer your question.

but, i have a question. why are you using DLLs, in the given vi, instead of calling its front panel directly,in the sub-panel cotnrols?

you are not controlling the vi through the DLL! you are anyways directly controlling it!

The final product is an application running on the Run-Time Package. The DLL-Modules should be exchangable without replacing the whole application.
