用VS2005怎么样制作一个WinCE的驱动程序？

[PatrickGamp]

我创建了一个VS2005的基于WM6 SDK的Win32 DLL工程，然后输入源代码，如下
#include <windows.h>
#include <tchar.h>

#define MAX_LENGTH 1024

HANDLE ghFile = NULL;

BOOL WINAPI DllEntryPoint(HANDLE hinstDLL, DWORD dwReason, LPVOID lpReserved)
{
return TRUE;
}

DWORD LOG_Init(DWORD dwContext)
{
ghFile = NULL;
return 1;
}

DWORD LOG_Deinit(DWORD dwContext)
{
ghFile = NULL;
return 1;
}

DWORD LOG_Open(DWORD hDeviceContext, DWORD dwAccessCode, DWORD dwShareMode)
{
ghFile = ::CreateFile(L"\\driver_log.txt", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ,
NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
return (ghFile != INVALID_HANDLE_VALUE);
}

DWORD LOG_Close(DWORD hOpenContext)
{
if (ghFile != NULL && ghFile != INVALID_HANDLE_VALUE)
{
::CloseHandle(ghFile);
ghFile = NULL;
return TRUE;
}
return FALSE;
}

BOOL LOG_IOControl(DWORD hOpenContext,
DWORD dwCode,
PBYTE pBufIn,
DWORD dwLenIn,
PBYTE pBufOut,
DWORD dwLenOut,
PDWORD pdwActualOut)
{
return TRUE;
}

void LOG_PowerDown(DWORD hDeviceContext)
{

}

void LOG_PowerUp(DWORD hDeviceContext)
{

}

DWORD LOG_Read(DWORD hOpenContext, LPVOID pBuffer, DWORD dwCount)
{
DWORD dwActualCount = 0;
if (::ReadFile(ghFile, pBuffer, dwCount, &dwActualCount, NULL))
{
return dwActualCount;
}
return 0;
}


DWORD LOG_Seek(DWORD hOpenContext, long lAmount, DWORD dwType)
{
return 0;
}

DWORD LOG_Write(DWORD hOpenContext, LPCVOID pBuffer, DWORD dwCount)
{
DWORD dwActualCount = 0;
if (::WriteFile(ghFile, pBuffer, dwCount, &dwActualCount, NULL))
{
return dwActualCount;
}
return 0;
}
然后创建一个def文件如下
LIBRARY "DriverLog"

EXPORTS

LOG_Init
LOG_Deinit
LOG_Open
LOG_Close
LOG_IOControl
LOG_PowerDown
LOG_PowerUp
LOG_Read
LOG_Seek
LOG_Write
然后手动在WM6模拟器上输入如下注册表值
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\DriverLog]
"Index" = dword:1
"Prefix" = "LOG"
"Dll" = "DriverLog.dll"
Order = dword:0
软重起模拟器

我的意图是创建一个虚拟的驱动程序，然后可以往 LOG1 端口里写入或者读取东西，可是为什么我的测试程序能够打开端口并写入，但是却读不出来，好像我的那个驱动根本就没有起作用？创建一个流接口的驱动程序的步骤到底应该怎么样？

看来这里无人揭帖，我又不能给自己加分，怎么办?

新的WINDOWS MOBILE6开发?你是用模拟器调试的么?直接通过Active Sync复制过去测试不行么?

感兴趣,但不太懂

去
硬件/嵌入开发 嵌入开发(WinCE)
论坛问问,那里是对路的地方
