各位老大，如何实现对IIS服务的控制啊？？主要包括停止服务、启动服务啊等等。因为我们的头头让我做一个远程管理IIS服务的东东，最主要是对WEB服务的操作啊，救命啊。
各位最好给段源代码读读，谢谢！
我把分追加到300分。
明天如果解决了此问题，下午18：00肯定结贴。如果没有顺延，多多赐教啊。
Stopping a Service
A service can be stopped with the ControlService function by sending a SERVICE_CONTROL_STOP request. If the SCM receives a SERVICE_CONTROL_STOP request for a service, it instructs the service to stop by forwarding the request to the services ServiceMain function. However, if the SCM determines that other running services are dependent on the specified service, it will not forward the stop request. Instead, it returns ERROR_DEPENDENT_SERVICES_RUNNING. Therefore, to programmatically stop such a service, you must first enumerate and stop its dependent services.
The following code implements a StopService function, which optionally attempts to stop the specified services dependent services.
#include <windows.h>
#include <tchar.h>
#include <stdio.h>
// This function attempts to stop a service. It allows the caller to // specify whether dependent services should also be stopped. It also
// accepts a timeout value, to prevent a scenario in which a service
// shutdown hangs, then the application stopping the service hangs.
//
// Parameters:
// hSCM - Handle to the service control manager.
// hService - Handle to the service to be stopped.
// fStopDependencies - Indicates whether to stop dependent services.
// dwTimeout - maximum time (in milliseconds) to wait
//
// If the operation is successful, returns ERROR_SUCCESS. Otherwise, // returns a system error code.
DWORD StopService( SC_HANDLE hSCM, SC_HANDLE hService,
BOOL fStopDependencies, DWORD dwTimeout )
{
SERVICE_STATUS ss;
DWORD dwStartTime = GetTickCount();
// Make sure the service is not already stopped
if ( !QueryServiceStatus( hService, &ss ) )
return GetLastError();
if ( ss.dwCurrentState == SERVICE_STOPPED )
return ERROR_SUCCESS;
// If a stop is pending, just wait for it
while ( ss.dwCurrentState == SERVICE_STOP_PENDING )
{
Sleep( ss.dwWaitHint );
if ( !QueryServiceStatus( hService, &ss ) )
return GetLastError();
if ( ss.dwCurrentState == SERVICE_STOPPED )
return ERROR_SUCCESS;
if ( GetTickCount() - dwStartTime > dwTimeout )
return ERROR_TIMEOUT;
}
// If the service is running, dependencies must be stopped first
if ( fStopDependencies )
{
DWORD i;
DWORD dwBytesNeeded;
DWORD dwCount;
LPENUM_SERVICE_STATUS lpDependencies = NULL;
ENUM_SERVICE_STATUS ess;
SC_HANDLE hDepService;
// Pass a zero-length buffer to get the required buffer size
if ( EnumDependentServices( hService, SERVICE_ACTIVE,
lpDependencies, 0, &dwBytesNeeded, &dwCount ) )
{
// If the Enum call succeeds, then there are no dependent
// services so do nothing
}
else
{
if ( GetLastError() != ERROR_MORE_DATA )
return GetLastError(); // Unexpected error
// Allocate a buffer for the dependencies
lpDependencies = (LPENUM_SERVICE_STATUS) HeapAlloc(
GetProcessHeap(), HEAP_ZERO_MEMORY, dwBytesNeeded );
if ( !lpDependencies )
return GetLastError();
__try {
// Enumerate the dependencies

for ( i = 0; i < dwCount; i++ )

if ( ss.dwCurrentState == SERVICE_STOPPED )
break;

return ERROR_TIMEOUT;
}
}
__finally
{
// Always release the service handle
CloseServiceHandle( hDepService );
}
}
}

HeapFree( GetProcessHeap(), 0, lpDependencies );
