如何在Windows注册表中设置值?(C ++) [英] How to set a value in windows registry? (C++)

问题描述

我要将键"HKEY_LOCAL_MACHINE \ Software \公司名称\游戏名称\设置\值"编辑为"1"(DWORD)

I want to edit key "HKEY_LOCAL_MACHINE\Software\company name\game name\settings\value" to "1" (DWORD)

这是我的代码:

HKEY hkey;
 DWORD dwDisposition;
 if(RegCreateKeyEx(HKEY_LOCAL_MACHINE, TEXT("Software\\company name\\game name\\settings"), 0, NULL, 0, 0, NULL, &hkey, &dwDisposition) == ERROR_SUCCESS){
  DWORD dwType, dwSize;
  dwType = REG_DWORD;
  dwSize = sizeof(DWORD);
  DWORD rofl = 1;
  RegSetValueEx(hkey, TEXT("value"), 0, dwType, (PBYTE)&rofl, dwSize); // does not create anything
  RegCloseKey(hkey);
 }

但是它什么也没做.RegCreateKeyEx()是唯一实际执行操作的函数:仅在注册表中创建文件夹".所以我又怎么失败了?我如何在注册表中创建文件"?

But it doesnt do anything. RegCreateKeyEx() is the only function that actually does something: creates the "folders" in the registry only. So once again how im failing? How i can create "files" in the registry?

推荐答案

始终检查API函数的返回值.您会看到RegSetValueEx()返回5，访问被拒绝.您没有要求写许可.修复:

Always check the return value of API functions. You'll see that RegSetValueEx() returns 5, access denied. You didn't ask for write permission. Fix:

  if(RegCreateKeyEx(HKEY_LOCAL_MACHINE, 
      TEXT("Software\\company name\\game name\\settings"), 
      0, NULL, 0, 
      KEY_WRITE, NULL, 
      &hkey, &dwDisposition) == ERROR_SUCCESS) {
    // etc..
  }
