Portable App Development

hi all.
I'm somehow new to this PA and NSIS world and sadly my English isn't so good to searching and questioning well . hope you understand my question correctly

----->>question :
I want to have a "conditional section" in my PortableApp launcher .

3 sections required :
--section a (that's my question)
--section b (integrating avisynth or whatever apps to localsystem)
--section c (integrate and run main program that "needs" avisynth (or whatever apps)integrated to the local system first)

(that's my question again)

Hi,
Today I encounter some issue when making a portable application.
There is a path storing in registry, and I use ConfigWrite to modify the path.
However, the registry imported is only the old one. The path is changed, but only changed in the file, instead of the real registry. When I close the application, the old registry values are exported to the registry file. Then the entire ConfigWrite doesn't work.
How can I write data first, and after that, import registry?
Here is the launcher.ini I used:

[Launch]
AppName=JPEGsnoopPortable
ProgramExecutable=JPEGsnoop\JPEGsnoop.exe

Hi,

I read PortableApps.com Launcher Manual, and I see launcher.ini that has section [ServiceN], but it said: "Services are currently disabled in the PortableApps.com Launcher." So Can I restore Services in PortableApps.com Launcher? What do I should with apps have services?

Anyone can help me! Thank you very much!

Files are downloaded to, in default, x:/downloads folder where x is the last hard drive in the system, so which is not fixed.
The download path setting is written in the xml file look like this:

{persist_settings}
{download}
{download_directory}{![CDATA[X:\downloads\]]}{/download_directory}

({ and } should be respectively. But I do not know how to make it correctly show in the post. Sorry about that.)

I'm creating launcher for 1 application that has in default enabled scheduler option and makes schedule for it with 1st run.
Can i do something to block that action?
I'm using non-code method.

I took a stab at compiling the new Greenfish Icon Editor Pro, which is now open source, in Lazarus IDE and it fails, unable to find a component called gfComp. Google and the Lazarus website are no help finding it. The source files will be downloadable here within about 10 minutes or so.

Assuming I have performed some changes at the lancher.ini file. Are these changes effective immediately or must I re-create the launcher?

Hi,

I used Stickies Portable and I have a question. StickiesPortable.ini file (App\AppInfo\Launcher) has command

[Launch]
WorkingDirectory=%PAL:DataDir%
DirectoryMoveOK=yes

And I test by remove WorkingDirectory=%PAL:DataDir% command then pack it by PortableApps.comLauncher again. As a result it leaves "stickies" folder in %Appdata%.

So I wonder which type of software can use command WorkingDirectory in [Launch]? I try some software but it can't work as Stickies Portable.

Hello!

I read manuals at https://portableapps.com/manuals/PortableApps.comLauncher/ref/envsub.html but it doesn't have environment variable for Program Files Directory? In NSIS has many environments such as $PROGRAMFILES, $DESKTOP...why PortableApps.com doesn't make own the same environment?

I make Dropbox Portable but it have Dropbox folder in Program Files. And I want to use DirectoryMoveOk in [Launch] to move it.

Anyone help me! Thank you very much!

If there are two executable files for one program, how can I deal with it? Can I make two launchers? How can I do that? Thanks.
