Title: _STARTDIR$ weirdness
Post by: SpriggsySpriggs on June 19, 2020, 02:18:22 pm
Is it an expected behavior of _STARTDIR$ to report the directory of the shortcut to the program rather than the directory that the EXE is starting in? I've had errors in some of my programs because it was using the desktop as the _STARTDIR$ since I used a shortcut. I've been using this to bypass that for now:
Code: QB64: [Select]
  1. $IF STDIR = UNDEFINED THEN
  2.     $LET STDIR = TRUE
  3.     FUNCTION StartDir$
  4.         DIM startupDir AS STRING
  5.         startupDir = COMMAND$(0)
  6.         startupDir = LEFT$(startupDir, _INSTRREV(startupDir, "\"))
  7.         StartDir = startupDir

Do you need meta commands to find the Source Folder for exe?

I don't think I have. Maybe Windows shortcut didn't goto the exe?

Update: Dang, I am sure there is command for exe path or folder, maybe it is a meta, I can't find it or recall it.

Dah!"https://www.qb64.org/wiki/STARTDIR$" copy/paste  OK time for lunch :P

I guess it has to do with whether "Start in" ("Iniciar em" in my pt-br screenshot) is set or left blank. Right-clicking your shortcut and choosing Properties returns something similar?

Another thing: you may want to use _CWD$ (current work dir) instead.

The main reason I don't want to use that too much is because I'm afraid I'll forget and use a CHDIR in my program which will screw up all my PowerShell calls that I like using.

The $IF and $LET is just because I had it in a BM and was using that for keeping errors out of the IDE from a possible second declaration in an $INCLUDE

Code: QB64: [Select]
  1. DIM SHARED startDir$
  2. startDir$ = _CWD$

Do that in the beginning of your program and you're golden. BTW, that's how _STARTDIR$ is generated at program startup in the c++ code:

Code: C++: [Select]
  1. //store _CWD$ for recall using _STARTDIR$ in startDir
  2.     startDir=qbs_new(0,0);
  3.     qbs_set(startDir,func__cwd());

I don't know why I didn't think of that. That's such a simple solution, too. Thanks!
