Portable App Development

I've just found a rogue directory being left behind by one of my dev tests, so in the next release I'd like to handle it automatically where it already exists on a users PC (plus it is about time I got my head around some NSIS).

The folder in question is %LOCALAPPDATA%\cache\picard, so I need to delete the picard folder if it exists (this I can do), then delete the cache dir if it is now empty (this I am stuck on).

The code so far:

!macro CustomCodePreInstall
   ${If} ${FileExists} "$LOCALAPPDATA\cache\picard\*.*"


How can i deal with this @(Default) Value?
what to take the place of it?

Hi, I'm trying to make my first PortableApp. It has been thirty years since I did any programming and fifteen since I mucked about in the Windows registry. With the Launcher and Installer, I thought I'd give it a try. I'm going to use generic names for the App I'm trying to convert. (I have contacted the developers and will pass my results on to them.)

The program is not designed to use the registry and I assume (yeah, I know) the entries I find are normal Windows housekeeping. It does use QT and I noticed that needs potential cleanup.

Hi !

Since last update, 12.0.2 and now still the same with version 12.0.3, every time i start the platform, i get this error.

Access violation at address 004998D1 in module 'PortableAppsPlatform.exe'. Read of address 00000054.

Clicking the only "ok" button starts the platform and no other error seems to appear, everything seems to work perfectly.

Just that annoying box at startup...

What should i do ?

Thanks

Hi,

I see a new feature which can close safely all apps when I close platform 12. But when I try to close portableapps.com menu I get this warning:

----------
The following portable apps are still running:
DittoPortable.exe
Ditto.exe

Please close all portable apps and try again.
----------

Google Chrome close itself automatically. But why Ditto still runinng? I try it many times, but I face the same problem.

Thank you

I am having problems with PortableApps.com Platform 12.0.
The error message is "Cannot focus a disabled or invisible window."

I have never faced this error before the 12.0 update.

The cause of the error is the new search textbox area(above the apps list area). After search and open a program via new search textbox, the PortableApps.com Platform 12.0 always show this error to me whether I open the platform via system tray icon click(Sometimes crashes application) or press the hotkey shortcut.

A “real” Portable PowerShell (e.g., https://portableapps.com/node/3922) is not what I’m after. I’ve begun to put together a portable set-up which is useable on systems that have PowerShell installed; this would be a launcher useable similarly to Command Prompt Portable.

Here’s PowerShellPortable.cmd:

@echo off

:: Home
set HomeDrive=%~d0
set HomePath=\Documents
set Home=%HomeDrive%%HomePath%

I just want to note that the "document" folders functionality is rather primitive. Apparently it has been this way for a long time.

I was pleasantly surprised to see that something like this is included. This is my first time installing PortableApps.

However, as Windows systems these days have at least 4 default "libraries", namely: "Documents", "Music", "Pictures" and "Videos", I would argue that having only three (with "Documents" acting as the root of those other three) is rather disingenious (I mean the antonym of "ingenious" ;-)).

Just Curios:
While examining Ditto Portable from the PA-Directory vs. the portable version from the author itself I realized that the PA-Version always deletes the ditto.settings ditto.db from the app directory after I closed.

Why does it do this? Would there be a problem leaving these files on the stick without relocating them?

I mean if my PC crashes the database isn't updated with newest entries.

Please enlighten me.

Hi,
I am trying to portablize a program. Everything is working fine, but for one thing. The program creates a file in the directory it opens a file from. So, lets say I open folder1\blah.ext the program will create "file.ext" in that folder. If I open a new file in let's say folder2\blahblah.ext it will create a new "file.ext" in that directory as well.
My question is how can I clean up those files on the exit of the program.
Thank you for the help.
