回答1:

 1、文件拷贝
  函数声明:
  FUNCTION boolean CopyFileA(ref string cfrom, ref string cto, boolean flag) LIBRARY "Kernel32.dll"
  调用:
  string ls_source, ls_des
  boolean lb_flag, lb_rtn
  lb_flag = false
  ls_source = "c:\book.xls" //源文件
  ls_des = "C:\tmp\111.xls" //目标文件
  lb_rtn = CopyFileA(ls_source, ls_des, lb_flag)
  MessageBox("文件拷贝", string(lb_rtn))
  2、删除文件
  函数声明:
  FUNCTION boolean DeleteFileA(ref string filename) LIBRARY "Kernel32.dll"
  调用:
  string ls_file
  boolean lb_rtn
  ls_file = "C:\tmp\111.xls"
  lb_rtn = DeleteFileA(ls_file)
  MessageBox("文件删除", string(lb_rtn))
  或者用PB本身的函数FileDelete()来删除文件。

pb 有文件操作 函数的 FileCopy FileDelete

FileCopy ("jazz.gif" ,"C:\emusic\jazz.gif", FALSE)
FileDelete("C:\emusic\jazz.gif")

具体的参数,返回值可以查看PB的帮助
