Creating Custom Protocol (Windows 7)

Windows Registry Editor Version 5.00[HKEY_CLASSES_ROOT\openphpfile]@="\"URL:openphpfile Protocol\"""EditFlags"=hex:02,00,00,00"URL Protocol"=""[HKEY_CLASSES_ROOT\openphpfile\DefaultIcon]@="\"C:\\Users\\ABC\\Documents\\Programs\\CB\\Chunks\\CGI.exe\",0"[HKEY_CLASSES_ROOT\openphpfile\shell][HKEY_CLASSES_ROOT\openphpfile\shell\open][HKEY_CLASSES_ROOT\openphpfile\shell\open\command]@="\"C:\\Users\\ABC\\Documents\\Programs\\CB\\Chunks\\CGI.exe\" -c \"%1\""

Basically the problem was with the underscores in your protocol.Once removed everything started working fine.You can change the path of executable as per your wish i.e. "C:\Program Files (x86)\NuSphere\7.0\phped.exe".

I tried openphpfile:blast and it worked quite nicely :)

EDIT:

the problem with this solution is that %1 gets replaced with "open_php_file://[file]" instead of just "[file]". This way I need some sort of filter that chops "open_php_file://".

put a space after openphpfile:[Space]Your_Content and change parameter to %2 you will get the expected result

[HKEY_CLASSES_ROOT\openphpfile\shell\open\command]@="\"C:\\Users\\ABC\\Documents\\Programs\\CB\\Chunks\\CGI.exe\" -c \"%2\""

Windows always replaces %1 with the full URI that was entered. AFAIK there is no way to change that behavior.

This leaves you two options:

1. If you've written the program being called yourself, you can filter the URI when it is being invoked.
2. You could use an intermediate program that acts as a filter for the URI and then forwards the result to the actual protocol implementation. Fortunately for you, someone has already done exactly that. See 'CustomURL' on CodePlex. CustomURL is a small utility for registering custom URL protocols. For example you can associate the rdp:// protocol with Remote Desktop Client or the ssh:// protocol with Putty or another SSH client.
