Get Connected Wizard API for Windows Vista

SFSxOI · Post by **SFSxOI** » Sun Aug 03, 2008 3:04 pm

This is for Windows Vista only.

Recently had a small project that needed me to launch a connection wizard from a small application. There are a few different ways to launch the wizard on Vista manually so this was a "Gee Whiz" creature comfort feature. Started digging thru the MSDN and found my answer. Its as simple as pie, so if anyone wants to know how to do this:

Cool, but it fails if compiled with Unicode. and considering that NT, 2000, XP, 2003 and Vista and 2008 are all Unicode. Well. kinda silly ain't it

This works fine, uses PB native code, less lines of code to type. Fixing the rest is just as easy.

Code: Select all

EnableExplicit

Procedure.l IsInternetConnected()
 Protected result.l=#False,dll.l=#Null
 dll=OpenLibrary(#PB_Any,"connect.dll")
 If dll
  If CallFunction(dll,"IsInternetConnected")=#S_OK
   result=#True
  EndIf
  CloseLibrary(dll)
 EndIf
 ProcedureReturn result
EndProcedure ;#True if connected, #False if not or error.

Debug IsInternetConnected()

Huh!

works fine here in unicode. Hmmm....

Well! It could be a Vista + IDE + that source, causing a issue.
Tested it again and the IDE crashed

I'm pondering if it could be the API loadlib or the API getproc,
don't recall if they are ANSI only or have Uni versions.

Yes, GetProcAddress_() requires ascii strings. Convert to ascii and it ran fine here in unicode mode.

@SFSxOI : why not use the PB library functions as they do all necessary unicode/ascii conversions?

He's probably one of those API purists. *gets beaten to a pulp*

LoL

Nope, not a purist. I just have the LoadLibrary and GetProcAddress thing memorized so its most prevelant in my projects because its just comfortable to use.

OK, here it is with just the PB library functions:
