Typically when I want to delete a file after the program stops running, I use atexit() and then remove(). Now I need to delete my Qt program itself (the .exe file) after it is done running. It's kind of like a self-destruction I need to achieve. Does Qt offer any solutions for that? I need to send my program to someone for testing. I then I need the program to delete itself because I don't want it to become public. What is the best way to achieve that with Qt? Thanks!
Hi,
You can create another application "deleteApp" that deletes the file of your application. When your application is going to close you can start the other application using a QProcess.
In your application you can check if the "deleteApp" file exists to let it start or not.
But Qt don't will provide this thing for you
Thanks a lot!
I could use a little bit of help with starting another application with QProcess as I've never done this.
Is there a short example on how this is generally achieved?
Hi,
You can use QProcess:startDeteched to start the second application.
The second application needs a delay to let the first application stop. There is a second way donig this that is using communication between the two applications.
