Introduction

The Need For Plug-in - I need it for the one of my installers.

Briefly: Use it when you need to find\kill a process when installing\uninstalling some application. Also, use it when you need to test the presence of a device driver.

Support

Supported platforms are: WinNT,Win2K,WinXP and Win2003 Server.

DLL Functions

Processes::FindProcess "process_name"

Searches the currently running processes for the given process name.

return on $R0:

1 - the process was found

0 - the process was not found

Processes::KillProcess "process_name"

Searches the currently running processes for the given process name. If the process is found then the it gets killed.

return on $R0:

1 - the process was found and killed

0 - the process was not found or the process cannot be killed (insufficient rights)

Processes::FindDevice "device_base_name"

Searches the installed devices drivers for the given device base name(important: I said BASE NAME not FILENAME).

return on $R0:

1 - the device driver was found

0 - the device driver was not found

Usage

First of all, does not matter where you use it. Of course, the routines must be called inside of a Section/Function scope.

Processes::FindProcess "process_name" ;without ".exe"
 
StrCmp $R0 "1" make_my_day noooooo
 
make_my_day:
...
;; 
 
noooooo:
...
 
 
Processes::KillProcess "process_name" ;without ".exe"
 
StrCmp $R0 "1" dead_meat why_wont_you_die
 
dead_meat:
...
 
why_wont_you_die:
...
 
 
Processes::FindDevice "device_base_name"
 
StrCmp $R0 "1" blabla more_blabla
 
blabla:
...
 
more_blabla:
...

Thanks

Sunil Kamath for inspiring me. I wanted to use its FindProcDLL but my requirements made it imposible.

Nullsoft for creating this very powerful installer. One big, free and full-featured (hmmm... and guiless for the moment) mean install machine!:)

One more thing...

If you use the plugin or its source-code, I would be appreciated if my name is mentioned.
