compatibility labwindow-labview

[TheGame]

Sorry for my bad explanations,

i have developped dll thanks to labwindows  where  i send  and  receive  frames with serial ports , and especially  RS232 library (openCom, ComWrt, ComRd)

Now i want to integrate these dlls in a labview environnement, so i want to continue to use the controls of read 

and write frames in my dll , but i would like to manage the opening and closing of the serial ports directly with the labview controls,

and i don't know if it is possible to combinate both.

Does your DLL use VISA? If it does, then you should be able to open the port in LabVIEW and pass the VISA reference to your DLL. If it doesn't, then I suspect the answer is no. The OS will will prevent two separate processes from accessing the same port. For example, you can't have a LabVIEW/VISA serial port session open as the same time as Hyperterminal.
