关于用VC写服务程序的一点小问题

Grim_Rapier 2013-11-18 05:38:24

请看以下程序：只列出主要函数的实现
#include <stdio.h>
#include <Windows.h>
#include <tchar.h>

TCHAR szServiceName[] = _T("MyTestService");
DWORD dwThreadID;
HANDLE hEvent = INVALID_HANDLE_VALUE;
SERVICE_STATUS status;
SERVICE_STATUS_HANDLE hServiceStatus;
void Init();
BOOL IsServiceInstalled();//TestService.exe /install
//TestService.exe /uninstall
BOOL InstallService();// Install service：
BOOL UninstallService();// Uninstall service：
BOOL ServiceCtrlStart();// Start service：
BOOL ServiceCtrlStop();// Stop service：
void WINAPI ServiceMain();
void WINAPI ServiceStrl(DWORD dwOpcode);
void LogEvent(LPCTSTR pszFormat, ...);
int main( int argc, char* argv[] )
{
Init();
dwThreadID = ::GetCurrentThreadId();
SERVICE_TABLE_ENTRY st[] =
{
{ szServiceName, (LPSERVICE_MAIN_FUNCTION)ServiceMain },
{ NULL, NULL }
};
LPSTR lpCmdLine = argv[1];
if ( argc == 2 )
{
BOOL bRet;
if (stricmp(lpCmdLine, "/install") == 0)
{
bRet = InstallService();
if ( bRet == TRUE )
{
printf( "Install service %s success", szServiceName );
}else
{
printf( "Install service %s failed", szServiceName );
}
}
else if (stricmp(lpCmdLine, "/uninstall") == 0)
{
bRet = UninstallService();
if ( bRet == TRUE )
{
printf( "Uninstall service %s success", szServiceName );
}else
{
printf( "Uninstall service %s failed", szServiceName );
}
}else if (stricmp(lpCmdLine, "/start") == 0)
{
bRet = ServiceCtrlStart();
if ( bRet == TRUE )
{
printf( "Start service %s success", szServiceName );
}else
{
printf( "Start service %s failed", szServiceName );
}
}else if (stricmp(lpCmdLine, "/stop") == 0)
{
bRet = ServiceCtrlStop();
if ( bRet == TRUE )
{
printf( "Stop service %s success", szServiceName );
}else
{
printf( "Stop service %s failed", szServiceName );
}
}
else
{
if (!::StartServiceCtrlDispatcher(st))
{
LogEvent(_T("Register Service Main Function Error!"));
}
}
}else
{
if (!::StartServiceCtrlDispatcher(st))
{
LogEvent(_T("Register Service Main Function Error!"));
}
}
return 0;
}
//服务主线程函数，即用户选择开启服务时调用的函数
void WINAPI ServiceMain()
{
// Register the control request handler
status.dwCurrentState = SERVICE_START_PENDING;
status.dwControlsAccepted = SERVICE_ACCEPT_STOP;
LogEvent(_T("ServiceMain"));
//注册服务控制
hServiceStatus = RegisterServiceCtrlHandler(szServiceName, ServiceStrl);
if (hServiceStatus == NULL)
{
LogEvent(_T("Handler not installed"));
return;
}
SetServiceStatus(hServiceStatus, &status);
//如下代码可以为启动服务前的准备工作
hEvent = ::CreateEvent( NULL, TRUE, FALSE, NULL );
if ( hEvent == NULL )
{
status.dwCurrentState = SERVICE_STOPPED;
SetServiceStatus(hServiceStatus, &status);
LogEvent(_T("Failure to start service"));
return;
}
//
//更改服务状态为启动
status.dwWin32ExitCode = S_OK;
status.dwCheckPoint = 0;
status.dwWaitHint = 0;
status.dwCurrentState = SERVICE_RUNNING;
SetServiceStatus(hServiceStatus, &status);
//等待用户选择停止服务，
//当然你也可以把你的服务代码用线程来执行，
//此时这里只需等待线程结束既可。
while ( WaitForSingleObject( hEvent, 1000 ) != WAIT_OBJECT_0 )
{
//模拟服务的运行，应用时将主要任务放于此即可
LogEvent(_T("Service runing..."));
::ShellExecute(NULL,"open","notepad.exe",NULL,NULL,SW_SHOW);//测试程序
}
//
//停止服务
status.dwCurrentState = SERVICE_STOPPED;
SetServiceStatus(hServiceStatus, &status);
LogEvent(_T("Service stopped"));
}
为测试程序，我在servicemain()中写了::ShellExecute(NULL,"open","notepad.exe",NULL,NULL,SW_SHOW);
所以服务启动后会打开记事本，但是安装，启动服务都成功后，并未执行记事本程序，即没有执行servicemain()函数，原因何在？
