CE5 WiFi开关

WinCE的WiFi开关要依赖于WiFi模块的休眠功能还有模块厂商提供的驱动里面有支持电源管理功能。这里面用的是SDIO86861模块，WinCE5的系统，S3C2416的CPU。

头文件要包括：
#include <winioctl.h>
#include <ntddndis.h>
#include <nuiouser.h>
#include <pm.h>

关键部分代码：

BOOL CDevCtrlDlg::OpenWiFiDriver(BOOL b_OpenDriver)
{
    if(b_OpenDriver)
    {
        //Delete Register
        reg.Create(HKEY_LOCAL_MACHINE, _T("Comm\\NdisPower"));
        reg.DeleteValue(_T("SDIO86861"));
        Sleep();

        //Power Up SDIO86861
        DevicePowerNotify(_T("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\\SDIO86861"), D0, POWER_NAME);
        SetDevicePower(_T("{98C5250D-C29A-4985-AE5F-AFE5367E5006}\\SDIO86861"), POWER_NAME, D0);
#if 0   //这里面因为电源开启之后驱动会自动把网卡开启，所以下面的操作可以不用。// Open NetworkCard
        WCHAR Name[]=_T("SDIO86861\0"); 

        HANDLE m_hFileHandle = CreateFile(_T(, , NULL,OPEN_EXISTING,  FILE_ATTRIBUTE_NORMAL, (HANDLE) INVALID_HANDLE_VALUE);
        if( m_hFileHandle == INVALID_HANDLE_VALUE )
        {
            RETAILMSG(, (TEXT("Failed To CreateFile NDS0!\r\n")));
            return FALSE;
        }
        else
        {
            RETAILMSG(, (TEXT("Succeed To CreateFile NDS0!\r\n")));
            //return TRUE;
        }

        BOOL SDIO86861Control=DeviceIoControl( m_hFileHandle, IOCTL_NDIS_BIND_ADAPTER, Name, , NULL, NULL );
        if(SDIO86861Control==TRUE)
        {
            RETAILMSG(, (TEXT("Succeed To Control SDIO86861!\r\n")));
            CloseHandle( m_hFileHandle );
            return TRUE;

        }
        else

            return FALSE;
        }
#endif
        return TRUE;
    }
    else
