How to get connector pane output programatically

[Karthikeyan_Mathiyalagan]

Hii Every one,

Actaully in my application i need to know in a sub vi connector pane what are the terminals connected to it.

for example simple addition.vi with 2 i/ps and 1 output..

i will connect the 3 variables in the connetor pane......

then from another vi i need to know what data is available in that addition.vi connectpr pane?? how to get it?? can any 1 explain me....

Hi Karthikey...,

what do you mean with "... what are the terminals connected to it."? Do you mean the type? Can you explain a bit more about what you try to do?

Which type do you use as input (Variant)?

Hii Mike

In a sub vi i connect different i/p's and o/p's like string,number(like I 32,double)etc....

Now i want to know what r the i/ps and o/ps connected in the connector pane with data types for each........

Hi Karthikey...,

so you have lots of inputs and outputs with different types and you want to know which are connected?

This thread discribes how you can check if an input is connected or not:

You can also use variant inputs, or an array of variants and use the "openg" function to get the connected type.

sorry mike i cann't understand can u explain me clearlyy

Hi Karthikey...,

which part do you mean? Is it correct that you have different inputs and you want to know which of them is connected? Can you explain why you need it? Maybe a polymorphic vi is the better solution for you.

ok using polymprphic vi how to get the solution for this???

One way to do it, is to go to help in the toolbar. Then use "search the Labview help", or "find Examples" option. Just seach for polymorphic

Hi Karthikey...,

navigate to "File -> New...". There you can select a polymorphic vi. Add all the your different vis and that's it.

Maybe it is rather leading to the desired result if you explain why you need to know this programmatically.

I asume that you are rather new to LabVIEW and miss some of the very basics of this language. I encountered such questions like yours only from programmers coming from C++/C# or other OOP-languages.....
