几个有用的Windows Mobile相关方法

1 取得设备ID

#include

extern "C" __declspec(dllimport)

BOOL KernelIoControl(

DWORD dwIoControlCode, LPVOID lpInBuf, DWORD nInBufSize,

LPVOID lpOutBuf, DWORD nOutBufSize, LPDWORD lpBytesReturned

);

#define IOCTL_HAL_GET_DEVICEID CTL_CODE(FILE_DEVICE_HAL, 21,

METHOD_BUFFERED, FILE_ANY_ACCESS)

CString GetSerialNumberFromKernelIoControl()

{

DWORD dwOutBytes;

const int nBuffSize = 4096;

byte arrOutBuff[nBuffSize];

BOOL bRes = ::KernelIoControl(IOCTL_HAL_GET_DEVICEID,

0, 0, arrOutBuff, nBuffSize, &dwOutBytes);

if (bRes) {

CString strDeviceInfo;

for (unsigned int i = 0; i
CString strNextChar;

strNextChar.Format(TEXT("%02X"), arrOutBuff);

strDeviceInfo += strNextChar;

}

CString strDeviceId =

strDeviceInfo.Mid(40,2) +

strDeviceInfo.Mid(45,9) +

strDeviceInfo.Mid(70,6);

return strDeviceId;

} else {

return _T("");

}

}

说明：Windows Mobile 5.0已经添加了专门的API完成此任务，对于2003以下的设备可以用

此方法。此方法是否能取道ID还取决与硬件制造商是否已经实现了改方法。因为

smartphone具备2-Tie安全性，所以此方法如果没有授权证书可能会调用失败。

2 取得设备信息

TCHAR wszMachineName[128];

SystemParametersInfo(SPI_GETOEMINFO, sizeof(wszMachineName),

&wszMachineName, 0);

取得设备OEM信息。

TCHAR wszVersion[256];

SystemParametersInfo(SPI_GETPLATFORMTYPE, sizeof(wszVersion),

&wszVersion, 0);

取得平台信息。

3 创建GUID

CString CreateGUID()

{

TCHAR wGuid[37];

SYSTEMTIME systime;

FILETIME filetime;

// construct GUID

GetSystemTime(&systime);

SystemTimeToFileTime(&systime,&filetime);

DWORD tick=GetTickCount();

DWORD highWord=filetime.dwHighDateTime+0x146BF4;

// convert GUID to a string

wsprintf(wGuid,TEXT("%08.8x-%04.4x-%04.4x-%04.4x-%04.4x%04.4x%04.4x"),

filetime.dwLowDateTime,

LOWORD(highWord),

HIWORD(highWord |0x10000000),

LOWORD(rand()),

HIWORD(tick),

LOWORD(tick),

LOWORD(rand()));

return CString(wGuid);

}
