Get the execution path of the current application//应用路径

[PB external function declaration]

FUNCTION int GetModuleFileNameA(&

ulong hinstModule, &

REF string lpszPath, &

ulong cchPath) LIBRARY "kernel32"

[Powerscript]

string ls_Path

unsignedlong lul_handle

ls_Path = space(1024)

lul_handle = Handle(GetApplication())

GetModuleFilenameA(lul_handle, ls_Path, 1024)

MessageBox("Current application path", ls_path)

//当前路径

First declare FUNCTION long GetCurrentDirectoryA( long length , ref string path) &

LIBRARY "Kernel32"

and then

long ll_ret

string ls_path

ls_path = Space(250)

ll_ret = GetCurrentDirectoryA(250, ls_path)

IF ll_ret > 0 THEN

ls_path = Left(ls_path,ll_ret)

MessageBoxBox("", ls_path)

ELSE

Messagebox("Error","Err GetCurrentDirectory " + String(ll_ret))

END IF

///改变当前路径

[FUNCTION DECLARATIONS]

FUNCTION boolean SetCurrentDirectoryA(ref string lpsdir) &

LIBRARY "kernel32.dll"

[powerscript]

String ls_Directory

ls_Directory = "C:\MyNewDirectory\" lb_Return = SetCurrentDirectoryA(ls_Directory)
