antenna rotator - ARSWIN communicating with labview?

[1231]

hi folks

i want to use labview to control, send commands to a program called ARSWIN, this program is used with hardware called ARS , (antenna rotator system). i have ARSWIN  installed, is there a way to use labview with it?

the ARS  h/w is used to control an antenna rotator attached and i would like to use labview to control the movements (via the ARSWIN program).

any help is much appreciated.

regards

I googled ARSWIN and found some references to it being a DDE server. Though an obsolete interface long abandoned by Microsoft, there are still DDE functions and a couple of examples that ship with LabVIEW. The functions are no longer on the palette but can be found in vi.lib\Platform\dde.llb.

DDE was something invented by Microsoft for inter-process communication. As I said, it's been obsolete for a long while. I found this example of DDE and ARSWIN. The DDE_App and DDE_Topic would be done by the LabVIEW DDE Open Conversation, the DDE_Item by DDE Srv Item, and the DDE_Send by the DDE Execute function. There's an app note here that might help.
