Launching URL's and .lnk files with different app

3 posts in this topic

I'm building a custom installer for DropMyRights and also to update the IE shortcuts on the Desktop, quickLaunch bar, and Start Menu to launch IE through DropMyRights, as well as an appropriate uninstall. That's all pretty easy but i'm having problems with one thing. How the heck to I update the registry so if a user clicks on a URL Shortcut that they may have on their desktop, or a URL in an email link to launch DropMyRights instead of IE directly.

Any Ideas?

Thanks,

Mike

Hi.Really nice idea.Solution it works for me under WIN XP SP2.

It uses Image File Execution Registry key.

It must do what you want to do.

#RequireAdmin
RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\myapps.exe")
RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\myapps.exe","Debugger","REG_SZ","%homedrive%\yourlauncher.exe")


#cs

HERE IS myapps.exe your 'emetized application' in eg. iexplore.exe


#ce





#cs
CONTENT OF yourlauncher.exe

echo off
runas /user:DroppedRights /savecred:typepasswordhere "firefox.exe"

and then compile it to exe(bat2exe) or use runwait() for this batch scenario and just compile it to yourlauncher.exe and place to %homedrive%\
DroppedRights here my restricted user account
typepasswordhere    here valid password for DroppedRights account.
You need only in first launch type password.In other authorisations it didnt require manual typing of password because /savecred is for remember password.

#ce

EDIT:homedrive% => %homedrive%

EDIT: %homedrive%\yourlauncher.exe must be your actual another application for example firefox.exe

so when myapps.exe when executed it will execute => %homedrive%\yourlauncher.exe => firefox.exe

So, i ran into an issue where DropMyRights doesn't seem to allow passing command line arguments to the target exe. The creator posted the code for it on his blog and i'm wondering if anyone here is able to convert to AutoIT? http://msdn.microsoft.com/en-us/library/ms972827.aspx
