[sane-devel] Network protocol implementation (fwd)

[Shailendra Mehta]

Hi,
Thanks for your help.
I have Xsane downloaded on windows.
But I want to change the GUI to make it more like other 
windows applications.
For that is net backend available as windows library?

Thanks again in advance

Regards
Shailendra
