Handling array with Dll

[Nagaa]

Hello every one 

I have made a dll with labview and i am calling the dll in labview only

I have given one input array and one output array to the connector pane and made this function as dll by adding 100 to the  input array internally.

But when i called that dll in another vi it shows input , output , len at input side and input 2 , output 2 , len 2 at output side 

But i am expecting to have one input , len and one output 

Please see the attached code

Thank you

This matches the way you configured the function prototype in the build specification for the library. For the behavior you want, in the build specification for the DLL, change the function prototype so that the IN parameter is an Input/Output parameter as shown below.

Is it possible to add Arguments in run time and configure its settings

The number and data types of function call parameters must be known when you configure the Call Library Function Node. Otherwise, how would you get data into and out of the DLL function?
