如果是win32控制台应用程序，我有以下代码可以正常运行
int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);

if( !InitBoard() )

}
HWND hDialog = 0;
hDialog = CreateDialog (hInst,
MAKEINTRESOURCE (IDD_MAIN),
0,
DialogProc);
if (!hDialog)
{
char buf [100];
wsprintf (buf, "Error x%x", GetLastError ());
MessageBox (0, buf, "CreateDialog", MB_ICONEXCLAMATION | MB_OK);
return 1;
}
#if !defined (_WRITE_MPEG_ )
InitBufferHandling();
StartRTPProcess();
// give vlc some time to get started before shoving buffers at it...
#endif
Sleep(250);
if( !StartAcquisition() )
return 1;
g_hWnd = hDialog;
// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))
{
if (!IsDialogMessage(hDialog, &msg))
{

我想将上面的代码转换为窗口服务，所以当我这样做时： -
void main()
{
SERVICE_TABLE_ENTRY ServiceTable[2];
ServiceTable[0].lpServiceName = "MemoryStatus";
ServiceTable[0].lpServiceProc = (LPSERVICE_MAIN_FUNCTION)ServiceMain;
ServiceTable[1].lpServiceName = NULL;
ServiceTable[1].lpServiceProc = NULL;
// Start the control dispatcher thread for our service
StartServiceCtrlDispatcher(ServiceTable);
}
// Service initialization
int InitService()
{
int result;
result = WriteToLog("Monitoring started.");
return(result);
}
void ServiceMain(int argc, char** argv)
{
int error;
MEMORYSTATUS memory;
char buffer[16];
int result;
ServiceStatus.dwServiceType = SERVICE_WIN32;
ServiceStatus.dwCurrentState = SERVICE_START_PENDING;
ServiceStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP | SERVICE_ACCEPT_SHUTDOWN;
ServiceStatus.dwWin32ExitCode = 0;
ServiceStatus.dwServiceSpecificExitCode = 0;
ServiceStatus.dwCheckPoint = 0;
ServiceStatus.dwWaitHint = 0;
hStatus = RegisterServiceCtrlHandler(
"MemoryStatus",
(LPHANDLER_FUNCTION)ControlHandler);
if (hStatus == (SERVICE_STATUS_HANDLE)0)
{
// Registering Control Handler failed
return;
}
// Initialize Service
error = InitService();
if (error)
{
// Initialization failed
ServiceStatus.dwCurrentState = SERVICE_STOPPED;
ServiceStatus.dwWin32ExitCode = -1;
SetServiceStatus(hStatus, &ServiceStatus);
return;
}
// We report the running status to SCM.
ServiceStatus.dwCurrentState = SERVICE_RUNNING;
SetServiceStatus (hStatus, &ServiceStatus);
// The worker loop of a service
while (ServiceStatus.dwCurrentState == SERVICE_RUNNING)
{void myfunc(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);
// TODO: Place code here.
MSG msg;
if( !InitBoard() )
{
return 1;
}
HWND hDialog = 0;
hDialog = CreateDialog (hInst,
MAKEINTRESOURCE (IDD_MAIN),
0,
DialogProc);
if (!hDialog)
{
char buf [100];
wsprintf (buf, "Error x%x", GetLastError ());
MessageBox (0, buf, "CreateDialog", MB_ICONEXCLAMATION | MB_OK);
return 1;
}
#if !defined (_WRITE_MPEG_ )
InitBufferHandling();
StartRTPProcess();
// give vlc some time to get started before shoving buffers at it...
#endif
Sleep(250);
if( !StartAcquisition() )
return 1;
g_hWnd = hDialog;
// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))
{
if (!IsDialogMessage(hDialog, &msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
//return (int) msg.wParam;
if (eventchecking)
{
ServiceStatus.dwCurrentState = SERVICE_STOPPED;
ServiceStatus.dwWin32ExitCode = -1;
SetServiceStatus(hStatus, &ServiceStatus);
return;
}
Sleep(SLEEP_TIME);
}
// return;
}
return;
}
它给出了错误C2601的错误：'myfunc'：本地函数定义是非法的
答案 0 :(得分：1)
从第二个代码块：
// The worker loop of a service
while (ServiceStatus.dwCurrentState == SERVICE_RUNNING)
{void myfunc(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);
你似乎遭受了重大影响。粘贴错误，将myfunc的定义粘贴到ServiceMain的中间。
同时查看代码的结尾：
Sleep(SLEEP_TIME);
}
// return;
}
return;
}
这种缩进是一种错误的迹象。
答案 1 :(得分：0)
注释掉while循环中的以下行 -
void myfunc(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
