(not funny but u r here)

i want to get info about my system :
(freediskspace,globlsize,OperatingSystem,OperatingSysVer,
VirtualDisks...)

how can i get all that info by API function.

[Steven McGarva]

Several APIs needed, try these:

I've dumped these here from an app i've developed that gets lots of information for the user. I can give you specific examples but your question was very generic. Ask

Why don't you ask the chicken?

thanks Steven ,

i know what API to use but i dont know what r the parameters
to send.

I've a lot of code that does what you want, email me and I'll return a text file with it. You can hack away at it or ask me smaller questions.

you can try a soft ware called API-Guide from http://kpdteam.tripod.com/apiguide/agreg.htm

it is free...it contains 521 APIs for vb. You can try it...it has all the apis that you wouldf need...it has examples, instructions and a quick search tool provided
