我如何自动删除我的Delphi程序？我试过这段代码：
procedure DeleteSelf;
var
module : HMODULE;
buf : array [ 0 .. MAX_PATH - 1 ] of char;
p : ULONG;
hKrnl32 : HMODULE;
pExitProcess,pDeleteFile,pFreeLibrary : pointer;
begin
module := GetModuleHandle ( nil );
GetModuleFileName ( module,buf,sizeof ( buf ) );
CloseHandle ( THandle ( 4 ) );
p := ULONG ( module ) + 1;
hKrnl32 := GetModuleHandle ( 'kernel32' );
pExitProcess := GetProcAddress ( hKrnl32,'ExitProcess' );
pDeleteFile := GetProcAddress ( hKrnl32,'DeleteFileA' );
pFreeLibrary := GetProcAddress ( hKrnl32,'FreeLibrary' );
asm
lea eax,buf
push 0
push 0
push eax
push pExitProcess
push p
push pDeleteFile
push pFreeLibrary
ret
end;
end;
您的代码仅在Windows NT和2000下运行.因为在这些操作系统中,系统保留对内存映射文件的usermode句柄引用,该文件支持磁盘上的可执行映像.在这些Windows版本中,此句柄始终具有值0x4.
删除自己的exe的最有效方法是创建一个处于挂起状态的子进程,注入代码等待父进程(exe删除),然后检测父进程何时退出,删除父进程,最后kill孩子的过程.
