windows 裝置管理器中的裝置控制

控制主要功能程式：

控制基本裝置：

GUID guid;

BOOL StateChange(HDEVINFO hDevInfo,DWORD dwNewState, DWORD dwDevID)

{

SP_PROPCHANGE_PARAMS PropChangeParams;

SP_DEVINFO_DATA DevInfoData = {sizeof(SP_DEVINFO_DATA)};

SP_DEVINSTALL_PARAMS devParams;

//查詢裝置資訊

if (!SetupDiEnumDeviceInfo( hDevInfo, dwDevID, &DevInfoData))

{

OutputDebugString("SetupDiEnumDeviceInfo FAILED");

return FALSE;

}

//設定裝置屬性變化參數

PropChangeParams.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);

PropChangeParams.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;

PropChangeParams.Scope = DICS_FLAG_GLOBAL; //使修改的屬性儲存在所有的硬體屬性檔案

PropChangeParams.StateChange = dwNewState;

PropChangeParams.HwProfile = 0;

//改變裝置屬性

if (!SetupDiSetClassInstallParams( hDevInfo,

&DevInfoData,

(SP_CLASSINSTALL_HEADER *)&PropChangeParams,

sizeof(PropChangeParams)))

{

OutputDebugString("SetupDiSetClassInstallParams FAILED");

return FALSE;

}

PropChangeParams.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);

PropChangeParams.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;

PropChangeParams.Scope = DICS_FLAG_CONFIGSPECIFIC;//使修改的屬性儲存在指定的屬性檔案

PropChangeParams.StateChange = dwNewState;

PropChangeParams.HwProfile = 0;

//改變裝置屬性并調用安裝服務

if (!SetupDiSetClassInstallParams( hDevInfo,

&DevInfoData,

(SP_CLASSINSTALL_HEADER *)&PropChangeParams,

sizeof(PropChangeParams)) ||

!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE, hDevInfo, &DevInfoData))

{

int nErr = GetLastError();

OutputDebugString("SetupDiSetClassInstallParams or SetupDiCallClassInstaller FAILED");

return FALSE;

}

else

{

//判斷是否需要重新啟動

devParams.cbSize = sizeof(devParams);

if (!SetupDiGetDeviceInstallParams( hDevInfo, &DevInfoData, &devParams))

{

OutputDebugString("SetupDiGetDeviceInstallParams FAILED");

return FALSE;

}

if (devParams.Flags & (DI_NEEDRESTART|DI_NEEDREBOOT))

{

OutputDebugString("Need Restart Computer");

return TRUE;

}

return TRUE;

}

注意事項：

1.32位系統和64位系統對應要編譯不同的程式。Setup..序列函數區分系統的

2. win7以後的系統開發時，一些API函數需要程式有管理者權限如Setup..族，編譯時項目-屬性-連接配接器-清單檔案-UAC執行級别選擇：requireAdministrator (/level='requireAdministrator') ，程式就會以管理者權限運作。

3.裝置句柄在程式中被占用時，會出現禁用函數成功傳回。需要重新開機電腦生效的情況。實際是禁用不成功，目前沒有找到問題，采用函數setup_remove移除了禁用失敗的裝置（setup_remove在裝置被占用時移除也會失敗）。

U盤禁用與裝置禁用是一樣的，這裡用裝置執行個體路徑來區分指定U盤
