Question

I have 2 programs:

program 1 – A Qt program written by me.

program 2 – A program not written by.

My goal is to run program 2 from program 1 ( I know how to do that).

My problem, however, is that program 2 has some .ini files which it looks for. It turns out that the directory program 2 looks in is not the directory of the executable, but rather the directory of the process starting the executable…in this case program 1.

so my error reads something like this:

“could not find file xxx.ini in directory C://directory of program 1//inifiles//…

my question is…is there any way I can go around this? I know it’s a little confusing, so please tell me if something doesn’t make sense.

Answer 1

Assuming you are using QProcess to start program 2, you need to set the working directory by calling QProcess::setWorkingDirectory(const QString &dir).

The documentation states:

Sets the working directory to dir. QProcess will start the process in
this directory. The default behavior is to start the process in the
working directory of the calling process.
