How to import an execution file into a Qt application?

[Kien Bui]

I have an execution file.
I want to import/attach/include,...(I don't know exactly) this file to project.
After build. I have a Qt application.
The first run Qt app, the an execution file export to path of Qt app.
How to do this?

even this isn't by far not very nice, but since u asked for:

put the executable into a qrc file and write it out:

QFile in(":/my/executable");
in.open( QFile::ReadOnly );

QFile out( QCoreApplication::applicationDirPath() % QString("/executableName") ); // next to the application executable
out.open( QFile::WriteOnly );

out.write( in.readAll() );
out.close();
in.close();

But you are advised to better distribute it along with your application, instead of embedding it with qrc.

Because my Qt app need exec a process with that file. Another way is compressed two files into a zip file.
I don't have better solution for this.

Don't understand what the relevance of that is. @raven-worx is suggesting that distributing the executable(s) as separate files is a better idea than embedding them into your executable with qrc and extracting them. And I agree with him. The fact that you will need to "exec a process with that file" has no bearing on how you distribute it, separately or embedded.

@JonB seperate. OK I will try with qrc. Tks

Just as note. embedding it and save to file to execute them might trigger a
heuristics scanner the user might be using. (Avast does)
Might not be issue in your case, but just be aware of it. :)
