Portable App Development

I need to develop an application which runs on Pen drive when inserted. If I create using Java and SQL, I dont have idea whether to keep data in system or pen drive. How to access my application when pen drive inserted and the database should be saved in pendrive itself.

It will be appreciated greatly.

Is it possible to split the Programs (not only App Data) and Documents as separate backup options. Sometimes one just want to backup your Apps only. It will save a lot of time if your Documents takes up most of the drive's space, it may consist mainly of Music which does not change often.

Fx. in Sandboxie when a folder is forced sandboxing, and an application in the folder is run then all its saves to documents folder or registry is virtualized. So why can´t portableApps catch those calls and place them automatically in data folder, why must they be specified in launcher.ini?

I downloaded a portable Maxthon browser and Emisoft detected variant.adware.graftor after installig.
So do something.

Need to make sure to check spelling of everything!!!

I have these XML file which needs to be edited at launch time:

<?xml version="1.0" encoding="UTF-8"?>
<installerDefaults pathToAllUsers="%DataDir%">
<databaseConnector>
<localDatabasePath>%DataDir%\some.file</localDatabasePath>
</databaseConnector>
<defaultLocales>
<installerDefaultLocale>en-US</installerDefaultLocale>
</defaultLocales>
<directories>
<languageDataBasePath>%DataDir%\Content</languageDataBasePath>


Ok I know this sound far fetched but would be something that I was thinking of.

I have multiple USB sticks/hard drives with various setups of PortableApss on them Including one sitting on a 500gb external USB 3 Drive that pretty much is always plugged into to same computer.

So here is idea:

WhoDat Portable is no longer functional due to ARIN changing the responses from their WHOIS server causing lookups to fail. So, WhoDat needs some fixing to work properly. The app is written in C++ using QT. The original base app has been abandoned by the developer but we have the source available on the WhoDat Portable homepage linked above. It's licensed under the GPL so we can continue developing it.

Does anyone know if these two work together on Windows?

I have written a program that works against the full version but our clients have Libre Office Portable installed and I am failing to get my program connected to Portable LibreOffice. I am getting a NoConnectException. Before I dig down any further I would like to know If I should try based on whether they do work or not? I have seem many questions about it not working on the Portable Libre Office website.

Hi - is there a way of setting some kind of password / security, so that others cannot change your settings?

Excellent project by the way..

Hello, I made a portable program using ThinApp, everything works well, but the program creates an icon in the system tray, can I get rid of it? And is it possible to combine all virtual processes in 1?
