Sending LabVIEW Boolean to LabWindows CVI

[RACEMAN]

I have inherited a simple CVI application that has a single front panel that contains two booleans. One closes the application. The other starts and stops the applications function which involves sending and receiving RS232 data.

I need to integrate this application into a LabVIEW application, I would prefer to not have the Front Panel come up (Just run in the background) and I want to be able to control the booleans.

What changes do I need to make to this CVI application in order to meet my needs.

Thanks for any help I may receive.

Hi,

Probably the fastest way to get this up a running will be to convert your CVI application into a DLL. Instead of creating an EXE project you create a DLL project that exposes some functions that LabVIEW can call.

I am attaching a sample DLL project and the VI to call that DLL. The architecture there is very common where you create an initialize function, a function to perform an action and another one to retrieve the data. You can use this template to paste the current code from the executable and call it in LabVIEW.

I hope this helps.
