在c++中编辑注册表项

#include <Windows.h>

int main() {
    HKEY hKey;
    LPCWSTR subKey = L"SOFTWARE\\MyApp";
    LONG result;

    // 打开或创建注册表项
    result = RegCreateKeyEx(HKEY_CURRENT_USER, subKey, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &hKey, NULL);
    if (result != ERROR_SUCCESS) {
        // 处理错误
        return 1;
    }

    // 设置注册表项的值
    LPCWSTR valueName = L"Version";
    LPCWSTR valueData = L"1.0";
    result = RegSetValueEx(hKey, valueName, 0, REG_SZ, (BYTE*)valueData, wcslen(valueData) * sizeof(wchar_t));
    if (result != ERROR_SUCCESS) {
        // 处理错误
        RegCloseKey(hKey);
        return 1;
    }

    // 关闭注册表项
    RegCloseKey(hKey);

    return 0;
}
