Portable App Development

My starter:
1. Creates a temporary file
2. Starts the application
3. Quits

The file is in use as long as the app is alive and a while longer.
Then I'd like to delete it.

Does the winapi task scheduling work on VERY limited accounts?
I haven't checked too carefully, because I doubt it does.
I tried
CreateFile( filePath, 0, FILE_SHARE_READ | FILE_SHARE_WRITE, 0,
OPEN_ALWAYS, FILE_FLAG_DELETE_ON_CLOSE, 0);
before starting the app, but it didn't work.

If you understand the paritual lagunage a programm is written in and you have the source and no licensing problems... What do you think about rebuilding the source?

Hi everyone...
I have developed pretty much PApps, but what I am doing is I am doing a
zip and then unzipped them to the location.. instead I really don't want to use winrar anymore I want to zip them in .paf format.

Please, HOW CAN I DO THAT?

When i managed, keep an eye out... as I will be posting about 5 new portable apps...
great stuff...

Hi,

Was just reading lifehacker, and found this nugget talking about a bit of software that allows you to install in a virtual layer that captures registry calls etc...

Maybe this could be used for portabalising apps?

I'm nearing completion on both my U3 and PortableApps versions.
Are there any licensing issues with any of the tools used? For example, do I contaminate my shareware license by using any of these open-source tools? I'm using NSIS to build a simple launcher, compressing with UPX and 7-Zip/SFX, and and have hacked the resulting .paf.exe with ResourceHack, inserting my own info.
Any problems here?

Is there a graphic library for those who would like to customize our installers to include the cute little (circle/arrow) PortableApps logo?
Is it permitted?
I would like to overlay the circle/arrow graphic onto my program's icon, to signify "My app's Installer".
I would expect that would be allowed, as it would help promote the PortableApps brand, while keeping mine intact. Is this ok, and are graphic files available?

Also, is there much point in going the extra mile here for the 7zip installers, with the new NSIS installers coming, or is that far enough in the future?
Thanks,

Newbie here,
I'm finalizing my U3 version, and figured I'd do PortableApps too. I'm not yet writing my script, but wanted to build the hooks into the main app first. With U3, I'm able to use Environment Strings to find path info, such as:
IShouldStoreMyDataHere := GetEnvironmentVariable('U3_APP_DATA_PATH');

Can I do this with NSIS? Or do I need it in conjunction with something else? Let me know if there is a sample app that does this. I looked through several, but maybe I didn't know what to look for.

I have written something for my company to help them secure documents on a USB stick. I'm getting on in years now, and never really progressed from the days of DOS batch scripts, so this is what I end up using, its not elegant, not clever, but it just about does what they want.

Today I found Portable Apps, and wondered if its something that I could use because its so much better than anything I'm likely to be able to create.

Does anyone have any suggestions or sites that I could use to learn NSIS?
Thanks
Ben

Is it possible to make parts of the registry portable? The most evil part of windows is the registry!!
