Using text file in resources for read and write in to text file.

@TheCeylann You can use
QCoreApplication::applicationDirPath(), likeQCoreApplication::applicationDirPath() + "/test.txt"@Bonnie This is the completely wrong directory - see my answer above: https://forum.qt.io/topic/134385/using-text-file-in-resources-for-read-and-write-in-to-text-file/6

@Christian-Ehrlicher I will store the password inside the text file. Uploading it somewhere can be a problem. Is there a way to define the file inside the file folder instead of defining it as full path. We can call files that are in the same folder like HTML only by their names. Is there a way to do this in Qt c++?

I don't know what your last post means. But yes you can specify a plain filename without a path toQFile(). The problem is where do you think that is sought relative to? It will be the current working directory your application has when it's running. And you essentially have no control over that, and don't know what it might be. It will not necessarily have any relation at all to where your executable is installed or where your other files involved in the build/installation might be.That is why you should use something based off
QStandardPaths, so you know where it actually is. -

The OP ask for a HTML-like way, so I feel he just want to store the file with the exe.
I'm sure he should also learn to use QStandardPaths. :) -

@Bonnie
But OP is asking to be able to write to file too, right? "HTML-like way" is not for writing to files, is it?wrote on 17 Feb 2022, 09:06 last edited by@JonB Right, but there're still quite many portable applications choose to store their configuration file, which could be both read and written, with the exe file.
QStandardPaths is not very friendly to portable applications though. -

Really? Under Linux??
And nowadays under Windows apps are installed into
Program Filesand Win 10+ doesn't allow users to write there any more, does it? -

@JonB No, of course Windows!
Portable applications are those without installers, they wouldn't be installed into Program Files :)wrote on 17 Feb 2022, 09:09 last edited by JonB@Bonnie
I didn't know it was Windows-only, thought it might be X-platform. But I had added to my post that nowadays you cannot write into WindowsProgram Files, can you?
Oh OK, you & I are cross-posting now.
Sometimes I run "portable apps" off a read-only USB stick....QStandardPaths is not very friendly to portable applications though.
What about e.g.
QStandardPaths::AppDataLocationor otherApp...ones? -

How could theApp...ones do that?
Sure there will be unwritable risks, but if the portablity is more important, then I have to accept that. -

Perhaps you had understood that the OP wishes to write to a file and then take that updated file to another computer, but I had not. Clearly that changes the equation! :)
