Portable App Development

I'm trying to learn how the launcher works, and make a program portable, by examining other PortableApps. I ran into trouble though. I found that FoxIt Portable uses the following in it's launcher.ini.

[DirectoriesMove]
-=%APPDATA%\Foxit Software\Foxit Reader
-=%APPDATA%\Foxit Software\RMS

This unfortunately, completely lost me. What is the -= at the beginning of those lines about? What I'm trying to do is this. I have a program that writes data to the location

%USERPROFILE%\.Arachnophilia

At the moment I'm figuring out, how to use GoogleChromePortable as local Browser for a CD-MP3-playback-system.

• Would it be difficult to add LocalHomepage-functionality to the ChromePortableLauncher?
• As I'm not familiar with NSIS, where can i get help?
• Where in the existing sources to insert this function?
• How to "compile" the exe?
• . . .

Why?

I'm making a launcher for an app that's already portable, and ran into a road block. There is an ini file in the Data\settings directory that contains the last drive and last directory the app was run from. My question is this, how do you deal with the portable app being moved.

So I got tired of typing out all the appinfo.ini files, so I made a program which will take the inputs and generate the file.
This is a beta software and is basic. All it can do right now is create/edit an appinfo.ini file. It has no error-checking yet. Also, I didn't include FileTypeCommandLine-extension or ProtocolCommandLine-extension because I didn't feel like parsing the field to add x number of inputs for each extension. I will in the next version, but I wrote this at 0230 today, and I was tired. But I decided to upload it to get comments about it.

I have some CLSID keys that have to be nulled on start OR deleted.
How i can do that? I found examples but are to messy to understand them.

My registy keys:

[HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{9E8D2FA3-591C-11D0-BF52-0020AF32BD64}]
@="Borland Midas DSCursor 1"

[HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{9E8D2FA3-591C-11D0-BF52-0020AF32BD64}\InProcServer32]
@="F:\\Odkurzacz13Portable\\App\\Odkurzacz\\MIDAS.DLL"
"ThreadingModel"="Apartment"

[HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{9E8D2FA3-591C-11D0-BF52-0020AF32BD64}\ProgID]
@="Borland.Midas_DSCursor.1"

Ok, so I am really struggling to understand parts of the installer.ini documentation. I do have issues with reading comprehension, so please be patient.

I posted a notice of my latest Development Test up at https://portableapps.com/development/test. The first two I did before at OpenPuff and MultiObfuscator are correct, but GameSave Manager, is not.

hey guys..

i seem to have run into a roadblock.
i've been working on this for a few days but can't seem to figure this out.

im making EasyBCD portable but it seems to leave HKLM\Software\NeoSmart Technologies
behind.

Here's my launcher.ini:
[RegistryKeys]
-=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\EasyBCD.exe
NeoSmart=HKLM\SOFTWARE\NeoSmart Technologies

it works fine on 32-bit, but my OS is 64-bit.

Other than the key being left behind, everything else seems to work.

Anyone know where im going wrong?

I tried to create a Plugin installer accordingly the instructions under No. 7 of the PortableApps.com Format™ 3.0 (2012-05-11). I have inserted the file plugininstaller.ini in the App\AppInfo directory. Only this file is contained in the App\AppInfo directory. The directory layout only contains the folder App and the appropriate subfolders and the folder Other. The file plugininstaller.ini is identical with the file appinfo.ini of the portable app that the plugin is used.

I have a bit of an odd problem.

I am using the 'Portable Python' from portablepython.com.
This package includes the PyScripter IDE.
I am fond, however, of working with IDLE, python's built in IDE.
I browsed through the contents of the portable app and found that IDLE could still be launched by running a batch file. The contents of the batch file appear to run a python script in the python engine to generate the IDLE GUI (I'm just guessing here, I can post the code if you like).
