在开发某些软件的时候，为了保护程序自身，就需要用到隐藏程序进程。以下通过实例来讲解隐藏程序进程的方法：  
  
1、创建一个新的项目   Project1  
选择File,New   Application。在表单Form1上放一Memo组件，一个OK按钮组件，改变OK按钮组件的Cation属性为   CreateProcess。再放一个timer组件。设置timer组件的Interval值为1000,每秒检查一次进程是否终止。  
  
2、在Unit1   Use节的Type后定义一个过程  
procedure   EstablishProcess;  
在Unit1   Use节的Var后定义一个变量：  
piProcInfoGPS:PROCESS_INFORMATION;  
  
3、在Unit1   implementation节中编写EstablishProcess过程的实现代码如下：  
procedure   EstablishProcess;  
Var  
  siStartupInfSTARTUPINFO;  
  saProcess,saThread:SECURITY_ATTRIBUTES;  
  fSuccess:boolean;  
begin  
  fSuccess:=false;  
  ZeroMemory(@siStartupInfo,sizeof(siStartupInfo));  
  siStartupInfo.cb:=sizeof(siStartupInfo);  
  saProcess.nLength:=sizeof(saProcess);  
  saProcess.lpSecurityDescriptor:=PChar(nil);  
  saProcess.bInheritHandle:=true;  
  saThread.nLength:=sizeof(saThread);  
  saThread.lpSecurityDescriptor:=PChar(nil);  
  saThread.bInheritHandle:=true;  
  fSuccess:=CreateProcess(PChar(nil),'c:\sr350\Sr350buff',@saProcess,@saThread,false,  
  CREATE_DEFAULT_ERROR_MODE,Pchar(nil),Pchar(nil),siStartupInfo,piProcInfoGPS);  
  if(   not   fSuccess)then  
    Form1.Memo1.Lines.Add('Create   Process   Sr350buff   fail.')  
  else  
    Form1.Memo1.Lines.Add('Create   Process   Sr350buff   success.')  
end;  
4、在CreateProcess按钮的OnClick事件中调用过程  
EstablishProcess；  
5、为Timer1的OnTimer事件编写代码：  
Procedure   TForm1.Timer1Timer(Sender:   TObject);  
Var  
  dwExitCode:DWORD;  
  fprocessExit:boolean;  
Begin  
  dwExitCode:=0;  
  fprocessExit:=false;  
  fprocessExit:=GetExitCodeProcess(piProcInfoGPS.hProcess,dwExitCode);  
  if(fprocessExit   and   (dwExitCode<>STILL_ACTIVE))then  
  begin  
    Memo1.Lines.Add('SR350buff.exe进程终止');  
    CloseHandle(piProcInfoGPS.hThread);  
    CloseHandle(piProcInfoGPS.hProcess);  
    EstablishProcess;  
  end;  
End;  
6、程序中设可执行文件名为c:\sr350\sr350buff.exe，所以c:盘\sr350目录下需有sr350buff.exe文件。  
7、编译联接，运行project1，单击CreateProcess可见c:\sr350\sr350buff.exe启动。关掉sr350buff.exe进程，可见sr350buff.exe自动再启动。
