How to enlarge the UDP Socket buffer size in LabView (on a Windows PC)

[Standardnutzer]

Hi everybody,

Does anyone know how to set the buffer size of a UDP-Socket in Labview on a Windows machine?

Thanks for any request...

The buffer size for UDP communication is handled by the OS and can't be set in LV. Maybe this can be changed somewhere in the registry but I don't have knowledge about that. Please check with Microsoft's support resources.

Jochen,

thanks for the reply. I couldn't find any possibility to modify the UDP socket parameters in Windows. I know that there are ways to do change socket values e.g. in Java. Somehow LabView should be able to do that too.

Unfortunately in LabVIEW there is really no direct method or property available to change this buffer size. If in JAVA there is a way to do that I suppose it's using some Windows SDK functions. Typically these are DLL calls so there is a chance that you might be able to accomplish that by calling a Windows System DLL but I really can't tell you which DLL and which function. Again, this should be documented at Microsoft .

Does anybody else know how to change the udp soket parameters in Windows?
