Portable App Development

I was trying to portableize a program that made registry entries in HKLM and HKCU. I was thinking about duplicating the registry section in the launcher to handle both. But it gets a little too complicated. Anyone know how to use NSIS to drop rights for a program? Anyone?
And while I'm at it, does anyone know how system::call works?????

i want to be able to read fragmentation percentage out of a log file created by jkdefrag from my autoit script. is this possible and how could it be done. The lines i'm interested are burried in with tons of other lines and look like this:

09:32:55 - Total size of fragmented items: 680427520 bytes, 166120 clusters, 4.8814% of all items, 4.2249% of disk

and if it would have to read line by line would this cause the app to eat up a ton of cpu?

I was bored, so I made a PAF template.
All you have to do is follow the readmes.

The PAF template is basically a template to make a Portable App. It's designed (Not really) for a beginner, except for the part about the NSIS launchers. A lot of people need something like this :).

AVG is a very good Anti Virus piece of software. It is free and very powerful. Millions of people are using it so having Anit-Vius on the go will be useful. ClamWin is not the best of all software so AVG will make computers even more secure.

Appriciate if it was put as a portable app

Thanks

I have an app I'm working on and I'm not sure how to handle it's registry entries. All the settings are stored in the registry and I'm not quite sure how to handle that. I know I'm supposed to put them into an .ini but where do I go from there? Do I copy them to the registry when the app runs then copy them from the registry in the .ini when the app closes? If so can somebody give me a line of code as example. Bare with me it's hard to pick examples out of the huge launchers.

I've noticed a lot of apps nowadays (that are in the beta forums) have skinning, so I was wondering if there would be portableapps.com skins/themes.
I know neorame is working on (for a few months, now) coolplayer portable, with extra features and a skin. I stink at art, so I was wondering if anyone would volunteer (or not, :P) to make portableapps skins/themes for apps.
I'm not demanding, just wondering.
Uh-oh, NO! Not the ear! NOOOOOOOOOOOOOOOOO!!!!!!

Recently, there's been a lot of 'stealing' other peoples' projects, for example typefaster, x-moto, ...
There has to be a way to make sure nobody 'takes' other peoples' project.
I have a few (probably not good) idea:

1. Make a What's being developed forum where people can register to make portable programs, then if somebody's already workin' on it, they can just leave a note. (Problem with this is that there would be a lot of bumping when people want to take over a project).

This is my first script (program) I did from scratch :).
It simply reads out of an INI file, then executes the paths.
I did make solutions for worst-case scenarios :P.

Didn't put this in beta testing because it felt awkward to me...
Dark yux made me!!!

PeaZip 2.0 was released few hours ago: this release completes the evolution PeaZip user interface sustained in 1.* series and set the new starting point for UI of 2.* series; UI development was expecially focused in enhancing usability of the application under many different aspect: improved context menus, more keyoboard shortcuts, smarter default behaviours etc...
The natively standalone package of PeaZip 2.0 is:
http://downloads.sourceforge.net/peazip/peazip_portable-2.0.bin.WINDOWS.zip

2.0 portable package features those changes against 1.11b:
peazip.exe was updated

what's the best way to pass a variable between different programs? I want NSIS to see which drives are HDD and not solid state and have it pass that information to my AutoIt program.
