1．讀注冊表 // 讀取注冊表 CString ReadRegisteTable(CString root,CString path, CString key) { HKEY hAppKey; LPCTSTR WINDS_SERVICE_REGISTRY_KEY=path; LPCTSTR DATA_FILE_SUB_KEY=key; char szDataFile[80]; if(root=="HKEY_LOCAL_MACHINE") { if (ERROR_SUCCESS == RegOpenKeyEx ( HKEY_LOCAL_MACHINE, WINDS_SERVICE_REGISTRY_KEY, 0, KEY_READ, &hAppKey)) { ULONG cbSize = MAX_PATH*sizeof(TCHAR); DWORD dwFlag = RegQueryValueEx ( hAppKey, DATA_FILE_SUB_KEY, NULL, NULL, (LPBYTE)szDataFile,&cbSize); RegCloseKey (hAppKey); if (ERROR_SUCCESS == dwFlag) { CString strDate=szDataFile; //MessageBox(strDate); if(strDate.GetLength()>0) return strDate; else return ""; } return ""; } } if(root=="HKEY_CURRENT_USER") { if (ERROR_SUCCESS == RegOpenKeyEx ( HKEY_CURRENT_USER, WINDS_SERVICE_REGISTRY_KEY, 0, KEY_READ, &hAppKey)) { ULONG cbSize = MAX_PATH*sizeof(TCHAR); DWORD dwFlag = RegQueryValueEx ( hAppKey, DATA_FILE_SUB_KEY, NULL, NULL, (LPBYTE)szDataFile,&cbSize); RegCloseKey (hAppKey); if (ERROR_SUCCESS == dwFlag) { CString strDate=szDataFile; //MessageBox(strDate); if(strDate.GetLength()>0) return strDate; else return ""; } return ""; } } return ""; }[nextqage] 2．寫注冊表 // 修改注冊表 BOOL ModifyRegisteTable(CString root,CString path, CString key, CString value) { HKEY hAppKey; DWORD dwDisposition = MAX_PATH*sizeof(TCHAR); LPCTSTR WINDS_SERVICE_REGISTRY_KEY=path; LPCTSTR DATA_FILE_SUB_KEY=key; char szDataFile[80]; strcpy(szDataFile,value); if(root=="HKEY_LOCAL_MACHINE") { if (ERROR_SUCCESS != RegCreateKeyEx ( HKEY_LOCAL_MACHINE, WINDS_SERVICE_REGISTRY_KEY, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &hAppKey, &dwDisposition)) { return false; } else { if (ERROR_SUCCESS != RegSetValueEx (hAppKey, DATA_FILE_SUB_KEY, 0, REG_SZ, (LPBYTE)szDataFile, (lstrlen (szDataFile)+1)*sizeof(TCHAR))) { return false; } RegCloseKey (hAppKey); } } if(root=="HKEY_CURRENT_USER") { if (ERROR_SUCCESS != RegCreateKeyEx ( HKEY_CURRENT_USER, WINDS_SERVICE_REGISTRY_KEY, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &hAppKey, &dwDisposition)) { return false; } else { if (ERROR_SUCCESS != RegSetValueEx (hAppKey, DATA_FILE_SUB_KEY, 0, REG_SZ, (LPBYTE)szDataFile, (lstrlen (szDataFile)+1)*sizeof(TCHAR))) { return false; } RegCloseKey (hAppKey); } } return true; } |
