RegQueryValueEx，需要一些帮助

编码方面的菜鸟，任何建议都值得赞赏。

这就是我要做的：

1） 在 HKLM 中打开运行键

2）阅读我制作的名为"测试"的REG_SZ。

3） 读取"测试"的数据

4）如果找到"此数据"，则删除密钥。

5） 关闭密钥。

我做错了什么？

#include <iostream>
#include <Windows.h>

using namespace std;

int main() {
char value[1024];
DWORD value_length = 1024;
DWORD keytype = REG_SZ;
HKEY hk;
LONG result;
LONG result2;
char response;
cout << "Would you like to scan? (Y) or (N)";
cin >> response;
if (response == 'Y')
{
    result = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Software\Microsoft\Windows\CurrentVersion\Run", 0, KEY_ALL_ACCESS | KEY_WOW64_64KEY, &hk);
        if ( result == ERROR_SUCCESS) {
            result2 = RegQueryValueEx(hk, ("Test"), NULL, &keytype, (LPBYTE)&value, &value_length);
            if (result2 == ERROR_ACCESS_DENIED) {
                cout << "Access Denied." << endl;
                RegCloseKey(hk);
                system("pause");
            }
            else if (result2 == ERROR_MORE_DATA) {
                cout << "lpData buffer is too small to receive the data." << endl;
                RegCloseKey(hk);
                system("pause");
            }
            else if (result2 == ERROR_FILE_NOT_FOUND) {
                cout << "Value does not exist for LpValueName." << endl;
                RegCloseKey(hk);
                system("pause");
            }
            else if (result2 == ERROR_SUCCESS) { //If the function succeeds, the return value is ERROR_SUCCESS.
                cout << "The value read from the registry is: " << value << endl;
                RegCloseKey(hk);
                system("pause");
            }
        }
        else if (result == ERROR_FILE_NOT_FOUND)
        {
            cout << "Key not found." << endl;
            system("pause");
        }
    }
    else if (response == 'N')
    {
        return 0;
        system("pause");
    }
}
