Good day,
I have a small application created in Lazarus / Free Pascal. If I run this application located in a folder on my computer, it will start and SQLite will create a temporary file .db-journal in the current directory. Since the application is portable, it will also run from a flash drive. And now comes the problem. Some computers (eg at work) do not allow writing to external media. Therefore, when I start the application, it does not start and an error is displayed that it is not possible to open the database (tested on a locked SD card). And so that the application does not always have to be copied to the computer, I would like to know if it is possible to redirect the creation of a temporary file .db-journal to another directory, for example the "C:\WINDOWS\USERS<user>" user directory. Is it usually possible to write there always?
Of course, I searched the net, but so far I have not found anything that would help me, so I am addressing you here. Thank you for your advice or guidance.

everybody. Sorry if I ask something trivial. I looked into the previously asked questions, to no avail. If the question was already asked, I beg your excuses, and please point me in the right direction.
I have a number of single form WinForms apps that I'm in the process of converting to appx for the store.
So far so good. No issues with that.
Despite, one of my apps uses the application folder to save some data to a temporary file
Dim sw As New StreamWriter(Application.StartupPath + "\somefile.csv", True)
The .exe program of course works with no issue.
The converted .appx program complains that I have no write permission to the WindowsApps and it subfolders. I quickly solved by taking ownership of the folder and give myself full control over it.
Do I have any chance to prevent the error message to appear on a generic machine, other than trivially changing the source code to point the temporary folder to some other path?
Clearly I don't want the admin to give the user full control over WindowsApps folder.
Writing to the package folder is not allowed. You need to change your code to write to a location that is writeable for the app/user, for example to the AppData folder.
This is documented in the Desktop Bridge preparation guide:

(it's the eighth bullet point)
I just started a new position replacing a developer who left abruptly working on a project that is based in the Kentico CMS. I am completely unfamiliar with ASP and Kentico, so the answer here needs to be tailored for a total beginner. I am familiar with other languages (PHP, Ruby, SQL, etc.) but have no idea where to begin with this.
So, want I am wanting to do is copy everything from our production site (db and all) to my local machine so I can develop on it easier. I have already exported the db into an SQL file, and copied all the files in our Kentico Instance folder into github, and cloned it on my local machine. I assume since Kentico is already "setup," going through the installation process in their documentation is not the way to go about this.
Any help would be incredibly appreciated!
David, basically there are a few "pieces" to running Kentico locally. Since, as you mentioned, Kentico is already set up, you should have an easier go of it.
A database with the necessary Kentico tables (it sound like you
already have this)
The codebase (all of the code files that you copied to github)
A valid license for any domain you want to run Kentico on. Was the site already public facing? Do you know what licenses you have
or can you log into the CMS Desk on the site that you copied
everything from?
Set up IIS for your local website. If you are unsure on this one I can explain further, but basically you need to add a new site,
point it to the root code folder for your site, and set the domain
to be a domain you have a Kentico license key for. You'll also need
to change the app pool settings to "integrated" mode (most likely)
and also set the appropriate version of .NET (if it's a recent
version of Kentico you'll want .NET 4.0)
Next you'll need to edit your hosts file to add the domain and point it to your localhost IP address. So add a line like "127.0.0.1
dev.yourdomain.com" or the equivalent.
Edit the web.config file so that your code can connect to your database. You will need to edit the connection string accordingly to
point to the database on your machine.
Once you have done these steps, your site should start to run just as it had before. I didn't give great detail on all of these pieces so let me know what problems you encounter so I can further clarify. More information about the current situation would also help.
One other note I would make: if you need the client to be able to review your work, it will most likely be more efficient and easier for you to leave the original database on the web server, and (if possible) connect to it remotely from your local machine. Since almost any change you make will result in a database change in Kentico, I find it much easier to be working on 1 database for development with distributed codebases. Otherwise you will probably need to overwrite the other database with your changes constantly and this can be annoying. If you leave the database on the server and just connect remotely, you can just ftp (or use git) to push files to the server that you have edited locally.
Before I attempt to program the following function myself, I wonder if something already exists.
What I would like to do is click an edit link on my website for a given document, and have that document launch in the native editor on my local machine (via a temporary file mechanism).
When I save the document in the native editor, the document is HTTP PUT back to the website. This can be accomplished by watching the file for writes, or watching the editor process for exit.
This way I can more easily edit documents on the web (instead of going through the download / edit / upload cycle).
My design would work as follows:
Register .webedit files on the local machine.
When a .webedit file is downloaded, launch webedit.exe with the file.
The file contains a URL (http://server/document) which is checked against a security database to ensure we're only opening allowed URLs.
The URL is downloaded to a temporary location.
The temporary file is launched in the native editor.
The file is watched for changes, and uploaded (HTTP PUT) on change detection (or when the editor is closed, if it's not a single-instance multiple-document editor).
Lots of FTP / SCP GUIs have this type of functionality, but I have not been able to find it for the web in general, or a shared library that allows you to plug in to this function.
Has anyone seen a program that does this?
SharePoint works like this.
It's great for managing shared documents in corporate environments.
Users can even checkout/checkin documents & the features are very extensible..you can customize pretty much anything if you know how.
Edit:
Since you're on Linux..i've heard that Alfreco is a great alternative.
I've never used it, but I know a couple organizations using it instead of SharePoint.
It integrates with Microsoft Office as well.
Also, it will definitely be cheaper.
I am currently working on a project where i need to store few files and folders in encrypted manner. This project will be platform independent and hence will be written in Java.
Instead of encrypting individual file and folder, we have been thinking of using some virtual file-system where a single container file will hold complete file-system.
Most of the open source virtual encrypted file-system tools we studied work on following principle.
mount the virtual file system (using secure password)
use this filesystem
finally dismount it
But the main problem here we face is that anyone who has access of the PC (e.g. network admin) will be able to see decrypted files when virtual drive is mounted. We want to restrict access to encrypted file system at process level. No one else in same OS session should be able to see the contents, hence no drive mounting, etc.
So we are looking for some open source tool which will provided some some APIs using which we will be able to access files in encrypted container without mounting it.
can anyone point us to any such library?
This thing I'd normally say was pretty cool.

But I've recently accidently copied a sub-repository in a mercurial repository to another folder and when that happened a lot of files got magically messed up. If you don't mind possible issues like that (eg. keeping backups) this could be a solution for you.
I've stumbled upon this question while hunting for an alternative because corrupted files are definitely not on my requirement list.
I have a Flex app that does a a fair amount of network traffic, it uses ExternalInterface to make some javascript calls (for SCORM), it loads XML files, images, video, audio and it has a series of modules that it could be loading at some point...
So the problem is - we now have a requirement where the user needs to run this content locally on a machine that is not connected to the internet (which means they can't connect to Adobe's site to change their security settings.) As you can imagine, when the user doubles clicks on the html page to launch this thing, they are greeted with a security warning that the swf is trying to communicate with another domain other than the one it's in. We can't wrap it in an exe or an AIR app so I unless there is some way to tweak some obscure security settings we may be hosed. Any idea's?
What you are trying to do is exactly the problem solved by AIR. You should really give it a try, it's not that hard to pick up. If you really really can't use AIR (you didn't specify why, so I assume it's just because you don't want to have to learn a new system), then modifying the security config file will solve the problem.
Basically what you need to do is create a 'trust' file in the "Global FlashPlayerTrust" directory. This can be done by your installer (which installs all the javascript, SWF, html, etc files onto the local machine). You should create the directory if it does not exist. The directory for each OS is:
Windows - %WINDIR%\System32\Macromed\Flash\FlashPlayerTrust
Mac - /Library/Application Support/Macromedia/FlashPlayerTrust
Linux - /etc/adobe/FlashPlayerTrust
Next, you need to create the trust file. You can name it anything, so pick a unique name that would be unlikely to conflict with others. Something like CompanyName.cfg. It's a text file, with one path per line. You can trust either one SWF at a time, or an entire directory. Example:
C:\Program Files\MyCompany\CoolApp
C:\Program Files\MyCompany\OtherApp\Main.swf
To test that it's working, inside your flash movie you can check System.security.sandboxType (ActionScript 1 or 2), or Security.sandboxType (ActionScript 3). It should have the value of "localTrusted"
I hesitate to say "you can't do it", but in my experience, there's no way to do what you're describing. Anyone, if I'm wrong, I'd love to know the trick.
Sorry that I haven't actually tried this to see if it works or not ... but ...
Page 20 (and/or 26) of this document may be of help. The document is referenced here. In a nutshell it describes directories which contain cfg files which in turn contain lists of locations on disk which should be regarded as trusted. An installer for the application would then be responsible for creating appropriate .cfg files in the desired location (global or for the installing user).
The short answer is that if your swf is compiled with use-network to true, it isn't going to work.
Is it possible to compile a version with use-network to false? Or is it running on an Intranet that is closed off from the Internet and still communicating with the LMS?
It is possible. Please chek that the swfs you are calling from the main swf have the "Access local files only" property enabled or not.
Did you try to specify the authorized domain with:
System.security.allowDomain("www.yourdomain.com");
