How to realize the copy and deletion of files in PB

How to implement the copy and deletion of the file in the PB, can be used with external functions

API function can be implemented:

1, file copy

Function declaration:

Function Boolean Copyfilea (Ref String CFROM, REF STRING CTO, Boolean Flag) Library "kernel32.dll"

transfer:

String ls_source, ls_des

Boolean LB_FLAG, LB_RTN

LB_FLAG = FALSE

Ls_source = "c: /book.xls" // Source file

LS_DES = "C: /TMP/111.xls" // Target File

LB_RTN = CopyFilea (LS_Source, LS_DES, LB_FLAG)

Messagebox ("file copy", string (lb_rtn))

2. Delete files

Function declaration:

Function Boolean Deletefilea (Ref string filename) library "kernel32.dll"

transfer:

String ls_file

Boolean LB_RTN

LS_FILE = "C: /TMP/111.xls"

lb_rtn = deletefilea (ls_file)

MessageBox ("File Delete", String (LB_RTN))

Or use the PB itself FileDelete () to delete the file.
