重启进程

方法一:

void CXXXDlg::RestartSoftWare()
{
::PostMessage(AfxGetMainWnd()->m_hWnd/*NULL*/, WM_SYSCOMMAND, SC_CLOSE, NULL);
//获取exe程序当前路径
extern CXXXApp theApp;
TCHAR szAppName[MAX_PATH];
::GetModuleFileName(theApp.m_hInstance, szAppName, MAX_PATH);
CString strAppFullName;
strAppFullName.Format(_T("%s"), szAppName);

//重启程序
STARTUPINFO StartInfo;
PROCESS_INFORMATION procStruct;
memset(&StartInfo, 0, sizeof(STARTUPINFO));
StartInfo.cb = sizeof(STARTUPINFO);
::CreateProcess(
(LPCTSTR)strAppFullName,
NULL,
NULL,
NULL,
FALSE,
NORMAL_PRIORITY_CLASS,
NULL,
NULL,
&StartInfo,
&procStruct);
}

方法二：

//启动

ShellExecute(NULL,"open","Path","","",SW_SHOW);

//关闭进程
UINT iProID=GetProcessIdByName(_T(".exe"));
HWND hWnd=ProcIDToMainHWND(iProID);
if(hWnd){
::SendMessage(hWnd,WM_CLOSE,0,0);
}

#include "tlhelp32.h"

// 2007.9.16
HWND ProcIDToMainHWND(DWORD a_hProcID)
{
int iCount=0;
HWND hWnd=::FindWindow(NULL,NULL);
DWORD hProcId;
while(hWnd!=0)
{
if(::GetParent(hWnd)==0)
{
//_MyGetWindowText(hWnd,chr,255);
GetWindowThreadProcessId(hWnd, &hProcId);
if(hProcId==a_hProcID){
return hWnd;
}
}
hWnd=::GetWindow(hWnd,GW_HWNDNEXT);
}
return 0;
}

// 根据进程反找主窗口句柄（稳定）
