在c＋＋程序中重启自己的一种方法

在工程.cpp文件(Project1.cpp)中加入：
#include "Unit1.h" 
WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) 
{ 
try 
{ 
Application->Initialize(); 
Application->CreateForm(__classid(TfrmMain), &frmMain); 
Application->Run(); 
} 
catch (Exception &exception) 
{ 
Application->ShowException(&exception); 
} 
catch (...) 
{ 
try 
{ 
throw Exception(""); 
} 
catch (Exception &exception) 
{ 
Application->ShowException(&exception); 
} 
} 

if(g_bIsRunAgain) 
{ 
AnsiString strPath; 
STARTUPINFO StartInfo; 
PROCESS_INFORMATION procStruct; 
memset(&StartInfo, 0, sizeof(STARTUPINFO)); 
StartInfo.cb = sizeof(STARTUPINFO); 
strPath = Application->ExeName; 
if(!::CreateProcess( 
(LPCTSTR) strPath.c_str(), 
NULL, 
NULL, 
NULL, 
FALSE, 
NORMAL_PRIORITY_CLASS, 
NULL, 
NULL, 
&StartInfo, 
&procStruct)) 
return 0; 
} 
return 0; 
} 


主窗口的单元头文件(Unit1.h)中加入： 
extern bool g_bIsRunAgain; 


主窗口的单元.cpp(Unit1.cpp)中加入： 
bool g_bIsRunAgain = false; 
//---------------------------------------------------------------------------- 
// 关闭程序 
void __fastcall TfrmMain::btnCloseClick(TObject *Sender) 
{ 
Close(); 
} 
//---------------------------------------------------------------------------- 
// 重启应用程序 
void __fastcall TfrmMain::btnReExcuteClick(TObject *Sender) 
{ 
g_bIsRunAgain = true; 
Close(); 
}
