我正在从注册表中查询数据,它被输出为 LPBYTE,这就是我卡住的地方。我需要将 LPBYTE 转换为我可以操作的数据类型,例如字符串。
到目前为止,这是我的代码
HKEY hk;
string poolID;
DWORD dwSize = 0;
DWORD dwDataType = 0;
DWORD dwValue;
LPBYTE lpValue = NULL;
CA2W registryLocation("Software\\Example");
// Check registry if exists, otherwise create.
LONG openReg = RegOpenKeyEx(HKEY_CURRENT_USER, registryLocation, 0, KEY_QUERY_VALUE, &hk);
if (openReg==ERROR_SUCCESS) { } else { cout << "Error (Could not open/create Registry Location)\n"; }
// Get buffer size
LONG getRegBuf = RegQueryValueExA(hk, "", 0, &dwDataType, lpValue, &dwSize);
if (getRegBuf==ERROR_SUCCESS) { cout << "Got reg key buf size\n"; } else { cout << "Error (registry key does not exist)/n"; intro(); }
lpValue = (LPBYTE)malloc(dwSize);
// Open reg value
LONG getReg = RegQueryValueExA(hk, "", 0, &dwDataType, (LPBYTE)&dwValue, &dwSize);
if (getReg==ERROR_SUCCESS) { cout << "Successful\n"; } else { cout << "Error\n"; }
cout << dwValue;
任何帮助或代码示例将不胜感激。
