Windows API: Passing null terminated arrays to PathFindOnPath 2003-08-31 -- John E. Christ III Newsgroups: softvelocity.products.c55ee
One more time... A line that wasn't supposed to be there (PathPtr[1] = 0)
somehow crept in.

For the non-UNICODE version
MODULE('Win32.lib')
PathFindOnPath(*CSTRING, LONG), LONG, RAW, PASCAL, DLL,|
NAME('PathFindOnPathA')
END
Data:
Filename CSTRING(256)
Paths CSTRING(256), DIM(100)
PathPtr LONG, DIM(100)
Code:
Filename = 'MyApp.app'
Paths[1] = 'c:\MyDir1'
PathPtr[1] = ADDRESS(Paths[1])
Paths[2] = 'c:\MyDir2'
PathPtr[2] = ADDRESS(Paths[2])
PathPtr[3] = 0 ! Null terminate the array of pointers
X# = PathFindOnPath(Filename, ADDRESS(PathPtr))
IF X#
MESSAGE('Found it!')
ELSE
MESSAGE('Didn''t find it!')
END
