Thanks for the reply. I downloaded the VB and VC version yesterday evening over my newly installed 2Mbps cable broadband (so expensive here in Singapore compared to Hong Kong, Korea and Japan?). It is not that bad : 1 hours and 40 minutes for VB and VC. Therefore it is not that big for broadband users. :) I installed the VB express beta II version and in a glance I do not see a compile to exe option like in VB 6. Maybe I need to look harder. I will check out the VC express version. I can remember where I come across the cost of the express edition but I remember something like US$49. Maybe I am wrong here.

Subject: RE: [EE] Host interface software programming language ... Where did you hear about that? It can't produce a standalone application? Well I think you have to register (or Microcost sometime refers it as activate) it. If not it will only work for 30 days. I think there is no time limit after you register it. I also believe there will be an official express edition for public download once it is really! >From Microsoft web site: - Small download makes it easy to get started I'm doubt over the last comment anyway. 516MB is considered small download? Never mind it's free anyway ;) Best regards, WH Tan -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
