Windoes Service Status ?

Rhino219

Hi all,

I have an C# Windows Service and a QT GUI. Now I want to check the running status out of the GUI.

I know that I get the status via dos command "sc query myserive"

Is there no method or instance to get the Servicestatus ?

Regards

First of all, this is no Qt related question.
You can use the windows service api.

If you follow this "link":http://www.lmgtfy.com/?q=windows+service+api , you come to this "result":http://msdn.microsoft.com/en-us/library/ms685141(v=vs.85).aspx

The question was if I can use a command like

QtService->getstatus("servicename");

Rhino219

Or like this. But this is C#

ServiceController sc = new ServiceController("Spooler", "Server1");

if (sc.Status == ServiceControllerStatus.Running)
{
MessageBox.Show("The service is running.");
}

The C# code uses the "Win32 Service api":http://msdn.microsoft.com/en-us/library/ms685942(v=VS.85).aspx , that can be done.
like this:

@
SC_HANDLE hScManager = OpenSCManager(0, // local computer or add computer name here
0, // SERVICES_ACTIVE_DATABASE database is opened by default.
GENERIC_READ); // onyl read info
if(0 != hScManager)
{
SC_HANDLE hSvc = OpenService(hScManager, // service manager
"Spooler", // service name
GENERIC_READ); // onyl read info
if(0 != hSvc)
{
SERVICE_STATUS_PROCESS sInfo;
DWORD bytesNeeded = 0;

        if(QueryServiceStatusEx(hSvc,                   // A handle to the service. 
                                SC_STATUS_PROCESS_INFO, // info requested
                                &sInfo,                 // structure to load info to
                                sizeof(sInfo),          // size of the buffer
                                &bytesNeeded))
        {
            if(sInfo.dwCurrentState == SERVICE_RUNNING)
            {
                QMessageBox::information(0, tr("MyApp"), tr("Service is running"));
            }
        }
    }
}

Thanks alot,

i have it. This is the working code.

@LPCWSTR ServiceName = L"My ServiceName";

SC_HANDLE hScManager = OpenSCManager(0, // local computer or add computer name here
0, // SERVICES_ACTIVE_DATABASE database is opened by default.
GENERIC_READ); // onyl read info
if(0 != hScManager)
{
SC_HANDLE hSvc = OpenService(hScManager, // service manager
ServiceName, // service name
GENERIC_READ); // onyl read info
if(0 != hSvc)
{
SERVICE_STATUS_PROCESS sInfo;

    DWORD bytesNeeded = 0;
     
    if(QueryServiceStatusEx(hSvc,                   // A handle to the service. 
                            SC_STATUS_PROCESS_INFO, // info requested
                            (LPBYTE)&sInfo,                 // structure to load info to
                            sizeof(sInfo),          // size of the buffer
                            &bytesNeeded))
    {
        if(sInfo.dwCurrentState == SERVICE_RUNNING)
        {
            traymessage("test", "start!!!", 3);
        }
        else
        {
              traymessage("test", "stop!!!", 3);
        }
    }
}
