Checking for connectivity in NSIS

Hello.

I'm trying to create a costom page in NSIS where the user can type an IP/Host-adress and check for connectivity by pressing a button. I can't seem to figure how to ping using this setup... so I'd like to ask for some assistance 🙂

Are you a developer who uses NSIS to distribute your application? Are you a Winamp plug-in developer who wants to use NSIS to distribute your plug-in? Have suggestions for other people like you? This is the place.

Calling "ping.exe" as an external program and the parsing its output (or checking the exit code) seems a bit inconvenient and error-prone.

Why not simply use the InternetCheckConnection() function instead?

InternetCheckConnectionA function (wininet.h) - Win32 apps

Allows an application to check if a connection to the Internet can be established. (ANSI)

System::Call "wininet::InternetCheckConnection(t 'http://www.example.com/', i {FLAG_ICC_FORCE_CONNECTION}, i 0) i .r0"

Should be ${FLAG_ICC_FORCE_CONNECTION}
