RE: [GD-Windows] Program directory

Isn't argument 0 to main the full path for the executable.

I think you can still get at the command line even if you are a windows =
app
and not a console app.

Subject: [GD-Windows] Program directory


Hi,
I would like to know how to retrieve the path where the program being
executed is. Usually it's the current working directory, that you can =
get
with getcwd, but in some cases that's not true. For example, when the
program is in the path or when you simply do: folder\program.exe
Is there any safe way of doing this?
I could save the name of the directory during installation or something =
like
that, but actually my program doesn't have any installation, so I would
prefer another option.

Yep, GetCommandLine() will do that.

This way is unreliable, don't do it.

Under an NT kernel the presence of a path on the command line depends on how
your program was started. Ditto using argv[0] as someone suggested..

Yes, the define _MAX_PATH and it's friends are well worth using in =
cases
like this.

Sadly GetModuleFileName doesn't return the length if the buffer you =
give is
too small, unlike other API calls.

That works fine, thanks!
BTW, I once had problems with those hardcoded string names when one =
client
installed my application under a very long file path...

Re: [GD-Windows] Program directory

Interestingly _MAX_PATH is defined to 260, and my max path was longer than
that, so it seems that I was doing something else wrong.

I've always used:

char Path[512];

not say that you can't have a path that long... But it fairly unlikely...
