WinCE中如何获取PDA的ID码

在PALM中﹐每台PDA都有唯一的ID碼﹐我想在WINCE中也應該有類似的ID碼﹐但如何在程序中獲取該ID碼﹖

答案就是PPC没有统一的Device ID
如果你为ipaq开发程序,那么两种方法可以取得device id:

1 Download Compaq iPAQ SDK 然后用 CPQInfoGetSerialNo function (定义在CPQInfo.h中)取得.

2 如果你只想用通用SDK,那么有一个取巧的办法,就是运行\windows\CreateAssetFile.exe ,然后读取自动生成的\windows\cpqAssetData.dat 文件, DeviceID就在里面, 这里有一段程序专门干这事:

1
CString GetSerialNumber()

2

3
{

4

5
//
Start CreateAssetFile.exe

6

7
PROCESS_INFORMATION pi;

8

9
if
(
!
::CreateProcess(TEXT(
"
\windows\CreateAssetFile.exe
"
),

10

11
NULL, NULL, NULL, FALSE,
0
, NULL, NULL, NULL,
&
pi))

12

13
{

14

15
m_strCompaqIpaqId
=
_T(
""
);

16

17
m_strErrorMessage
+=
_T(
"
Cannot run \windows\CreateAssetFile.exe file.
"
);

18

19
return
TEXT(
""
);

20

21
}

22

23

24

25
//
Wait until CreateAssetFile.exe will be finished

26

27
::WaitForSingleObject(pi.hProcess, INFINITE);

28

29

30

31
//
Read data from cpqAssetData.dat file

32

33
HANDLE hInFile;

34

35
TCHAR strSN[
65
];

36

37
DWORD dwBytesRead;

38

39
hInFile
=
CreateFile(TEXT(
"
\windows\cpqAssetData.dat
"
), GENERIC_READ,

40

41
FILE_SHARE_READ, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL,
0
);

42

43

44

45
if
(hInFile
==
INVALID_HANDLE_VALUE) {

46

47
m_strCompaqIpaqId
=
_T(
""
);

48

49
m_strErrorMessage
+=
_T(
"
Cannot read \windows\cpqAssetData.dat file.
"
);

50

51
return
TEXT(
""
);

52

53
}

54

55

56

57
SetFilePointer(hInFile,
976
, NULL, FILE_BEGIN);

58

59
memset(strSN,
0
,
64

*

sizeof
(TCHAR));

60

61
ReadFile(hInFile,
&
strSN,
64
,
&
dwBytesRead, NULL);

62

63
CloseHandle(hInFile);

64

65

66

67
return
CString(strSN);

68

69
}
