My curiosity has gotten he better of me. What is the purpose of the rundll32 part of the command?
Rundll32 is a Windows program that calls an exported function in a DLL. If you have no idea what that means, consider this:
a) a DLL on Windows is like a SRVPGM on iSeries.b) an exported function on Windows is like an exported subprocedure on iSeries.
So it's basically a program that can call any function (subprocedure) in any DLL (service program) from the command-line without having to write a special program to handle it. The example that we've been discussing launches a DLL called URL.DLL which is included with Windows. Inside that DLL is a routine called FileProtocolHandler which accepts one parameter, the name of the file that it should find the handler for. It'll then launch that program and execute the filename.
Since a "filename" starting with http:// is supposed to be handled by a web browser, it'll open up the browser and navigate to the URL that you specified. (If that makes any sense.)
Here's another example, that calls the "Control_RunDLL" routine in the Shell32.dll file. Control_RunDLL is a function that was added to let RunDLL open up the Windows Control Panel and run one of the control panel applets inside. For example, this opens the time & date applet:
midrange.com
strpccmd pccmd('rundll32 shell32,Control_RunDLL timedate.cpl')
