今天刚开始学习RAPI编程，先将今天学习的成果放出来，大家学习。
如果代码有问题，请提出，多谢!
在PC上使用VC6，好久没有用它了。一直在EVC4下编程，呵呵...
RAPI功能的实现，需要rapi.dll和rapi.h。在以下的实现中，Link的动态库是: C:/WINDOWS/system32/rapi.dll。没有使用rapi.h头文件，只是将必要的结构定义复制到工程中。如RAPIINIT 的定义。对动态库中的函数，用GetProcAddress()来加载。
1. RAPI初始化
1 BOOL CVogueRAPI::InitRapi() 2 { 3 LPTSTR pDllPath = new TCHAR[MAX_PATH + 10]; 4 GetSystemDirectory(pDllPath, MAX_PATH); 5 CString strDllPathName(pDllPath); 6 strDllPathName += "//Rapi.dll"; 7 TRACE("%s/n",strDllPathName); //C:/WINDOWS/system32/rapi.dll 8 hInst = LoadLibrary(strDllPathName); 9 if(hInst) 10 { 11 //CeRapiInit = (FARPROC) GetProcAddress(hInst, "CeRapiInit"); 12 CeRapiInitEx = (pfnFnucA) GetProcAddress(hInst, "CeRapiInitEx"); 13 CeRapiUninit = (FARPROC) GetProcAddress(hInst, "CeRapiUninit"); 14 CeCreateFile = (pfnFunc0)GetProcAddress(hInst, "CeCreateFile"); 15 CeWriteFile = (pfnFunc1)GetProcAddress(hInst, "CeWriteFile"); 16 CeCloseHandle = (pfnFunc2)GetProcAddress(hInst, "CeCloseHandle"); 17 CeFindFirstFile = (pfnFunc3)GetProcAddress(hInst, "CeFindFirstFile"); 18 CeGetFileSize = (pfnFunc4)GetProcAddress(hInst, "CeGetFileSize"); 19 CeReadFile = (pfnFunc5)GetProcAddress(hInst, "CeReadFile"); 20 CeFindNextFile = (pfnFunc6)GetProcAddress(hInst, "CeFindNextFile"); 21 CeCreateDirectory = (pfnFunc7)GetProcAddress(hInst, "CeCreateDirectory"); 22 CeCreateProcess = (pfnFunc8)GetProcAddress(hInst, "CeCreateProcess"); 23 CeGetSystemInfo = (pfnFunc9)GetProcAddress(hInst, "CeGetSystemInfo"); 24 return TRUE; 25 } 26 else 27 { 28 FreeLibrary(hInst); 29 return FALSE; 30 } 31 return FALSE; 32 }
2. 设备与PC连接
1 BOOL CVogueRAPI::RapiConnectDevice() 2 { 3 RAPIINIT struRapiInit; //CeRapiInitEx函数要求的入口参数: 定义在rapi.h中, 为了不include "rapi.h", 将其定义复制到工程中 4 DWORD dwWaitResult = 0; //等待初始化完成事件的变量 5 HRESULT hRapiResult = NULL; //CeRapiInitEx的返回HANDLE 6 7 if(m_bRapiInitFlag == FALSE) //全局的一个标志,如果初始化成功就不再重复 8 { 9 struRapiInit.cbSize = sizeof(RAPIINIT); //填满该结构体仅有的三个成员 10 struRapiInit.hrRapiInit = NULL; //明知是输出参数也顺手填一下, 以防万一 11 struRapiInit.heRapiInit = NULL; 12 13 hRapiResult = CeRapiInitEx(&struRapiInit); //关键点 14 dwWaitResult = WaitForSingleObject(struRapiInit.heRapiInit, 2000); //关键点 15 16 if(hRapiResult == S_OK && struRapiInit.hrRapiInit == S_OK && 17 dwWaitResult != WAIT_TIMEOUT) //三个返回值都判断, 以保证正确性 18 { 19 m_bRapiInitFlag = TRUE; 20 return TRUE; 21 } 22 else 23 { 24 return FALSE; 25 } 26 } 27 else 28 { 29 m_bRapiInitFlag = TRUE; 30 return TRUE; 31 } 32 }
3. 从PC传输文件到设备
1 BOOL CVogueRAPI::CopyFiletoWinCE(CString csPCFilename, CString csCEFilename) 2 { 3 CFile PCFile; 4 HANDLE hCEFile; 5 char cTemp[BUFFER_SIZE]; 6 DWORD nbytes = 0; 7 int iFileLen = 0; 8 int iFileNum = 0; 9 int i = 0; 10 PCFile.Open(csPCFilename, CFile::modeRead |CFile::typeBinary); 11 iFileLen = PCFile.GetLength(); 12 iFileNum = iFileLen / BUFFER_SIZE; 13 BSTR bstr = csCEFilename.AllocSysString(); 14 SysFreeString(bstr); 15 hCEFile = CeCreateFile(bstr, GENERIC_READ | GENERIC_WRITE, 0, NULL, 16 OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); 17 if(INVALID_HANDLE_VALUE == hCEFile) //文件打开失败 18 { 19 return FALSE; 20 } 21 22 for(i = 0;i < iFileNum;i++) 23 { 24 memset(cTemp,0,sizeof(char) * BUFFER_SIZE); 25 if(PCFile.Read(cTemp, BUFFER_SIZE) >= 1) 26 { 27 CeWriteFile(hCEFile, cTemp, BUFFER_SIZE, &nbytes, NULL); 28 } 29 } 30 memset(cTemp,0,sizeof(char) * BUFFER_SIZE); 31 if(PCFile.Read(cTemp, iFileLen % BUFFER_SIZE) >= 1) 32 { 33 CeWriteFile(hCEFile, cTemp, iFileLen % BUFFER_SIZE, &nbytes, NULL); 34 } 35 CeCloseHandle(hCEFile); 36 PCFile.Close(); 37 CeRapiUninit(); 38 return TRUE; 39 }
