Portable App Development

I was recently looking at the MediaMonkey Portable launcher and noticed that a folder is left at C:\Users\[username]\AppData\Local\ in Windows7. The folder is removed in XP, so obviously something's changed. The settings and everything are moved properly, but an empty folder is left and not removed. I've posted the cleanup code below, but I don't know what's wrong. Can somebody take a look at this?

EDIT: Topic moved to MediaMonkey Launcher topic.

Look -- I might not know what I'm talking about here -- but I was just looking at the NSIS FAQ, and came across this: File Association

I'm going to assume that most of you NSIS wizards know about all that, it seems a pretty elementary function, doesn't look at all complicated.

So... couldn't certain launchers use that?

I notice that most portable app launchers use a fairly sizeable chunk of memory, relatively speaking. 10 MB seems to be the average.

I'm wondering why this is - and why a Windows API call to say 'EmptyWorkingSet' isn't made upon main program launch?

Thanks for any info,
J

Hello,

I have read many posts regarding the support of 64-bit platforms by Portable Apps, but most of them I think revolve around compatibility of 32-bit applications.
Here we are facing a particular challenge: our portable Java application relies on JNI programs for specific integration with the host (mail, smartcards, etc.) which in turn rely with host specific programs.

When these specific programs are compiled for a 64-bit host, then we have to recompile our JNIs in 64-bit and thus we need A 64-BIT PORTABLE JAVA RUNTIME ENVIRONMENT !!!

Are there any plans for this ?

I'm working on an online installer right now, and for some reason it can't seem to handle folders with dollar signs in the folder name. Here's the installer's file structure:

topocr.exe [installer]
-----topocr.exe [application]
-----$COMMONFILES
----------[a lot of files here]
-----$PLUGINSDIR
----------[a lot more files here]

Here's a sample installer.ini I've tried:

[DownloadFiles]
DownloadURL=http://www.topocr.com/topocr.exe
DownloadName=TopOCR
DownloadFilename=topocrinstaller.exe
DownloadMD5=d2438258b5eb61a6357a27984f84866e

I'm working on an online installer for TopOCR; however, the AdvancedExtract1To parameter seems to be failing. It correctly creates the folder, but doesn't extract the installer's files into that folder.
I know it should be able to, since 7-Zip shows the embedded files without a hitch... anyone know what the problem might be?

Here's my installer.ini:

Hi,

I've just finished making TopOCR, a great OCR program, portable.
I need to clarify a couple of things before I post it here, though...

* I've been unable to find a spelled-out license; the only "license" I've been able to find is freeware. Any problem with that?

* Can I make a live (online) installer, or am I stuck just posting the launcher?

* I assume I need to get permission from TopOCR, right? I did manage to find a contact e-mail address on their site...

Hi, I'm hoping you can give me some ideas...

I'm building a "game" to train pollution control operators. The game must have the following characteristics:
* Run off a USB drive on Windows machines (not a web-based app)
* Contain a main window that shows equipment operations and contains 10-15 data entry fields (some textboxes, some drop downs, maybe a slider or two)
* Intensive background calculations (calculus)
* Several tabs or popups to collect info about transactions (eg, purchasing inputs, selling/disposing waste)

Need these apps made portable I would like to do it but no clue just a beginner apps at http://www.piriform.com/
