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 John
