SetCurrentDirectoryA Doesn't Work

[Former Member]

I'm trying to dynamically configure the working directory by calling the external kernel32 SetCurrentDirectoryA function, but no matter what I pass in as the path, it always seems to return false. What would make that happen? I'm using PB 12.6 classic on Win 10 desktop.

You have to declare the function such that PowerBuilder is treating the string as ANSI, i.e.,

FUNCTION long GetCurrentDirectory( long length , ref string path) LIBRARY "KERNEL32" ALIAS "GetCurrentDirectoryA;ANSI"

Alteratively, you could simply call GetCurrentDirectoryW as that would bypass the conversion.
