So I have this application installed on my computer that have independently added sort of a prefix to allow IE/Any browser to link directly to that app.

For example:


Will launch the application and do some stuff with the ID at the end of the string

So if I place that bit in Start->Run, it works. It successfuly launches the app. But if I paste the same string in cmd.exe window it fails to launch.

These "prefixes" (http:, ftp:, appname:) are called URI schemes. – grawity May 8 '12 at 15:25

Prefix it with start when you use it in cmd.exe, i.e. start, start appname://open/555890405.

cmd.exe expects the first space-delimited token you enter to be an internal command, drive letter specification, or filename - not a URL. But the start command supports that.

Thanks, this works! Is there any way of running that uri scheme directly through an AutoIt script? I have the Run() function, but even if I place start appname://open/555890405 in it it doesn't work. I guess it's expecting to get a filename for an application. – Or W May 8 '12 at 15:30
try cmd /c "start appname://open/555890405" – LawrenceC May 8 '12 at 15:36
Thanks, this works perfectly. – Or W May 8 '12 at 15:38
@OrW: Use ShellExecute -- the same function as used by the Start - Run dialog. – grawity May 8 '12 at 15:43
