[英]WINAPI: Windows Registry functions fail
I have a trouble writing some keys into registry: 我在注册表中写入一些密钥很麻烦:
PHKEY key = NULL; HRESULT hResult = S_FALSE;
hResult = RegOpenKeyEx(HKEY_CLASSES_ROOT, _T("AppID"), 0, KEY_CREATE_SUB_KEY, key);
and this fails with code 0x00000057 - The parameter is incorrect.
并且失败,代码为0x00000057 - The parameter is incorrect.
hResult = RegCreateKeyEx(HKEY_CLASSES_ROOT, _T("new_key_name"), 0, NULL,
REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, key, NULL);
this fails with code 0x000003f2 - The configuration registry key is invalid.
这将失败,代码为0x000003f2 - The configuration registry key is invalid.
I have also tried some variations, but the result is always the same. 我也尝试了一些变体,但结果始终相同。 I was using this functions before and never had a problem. 我以前使用过此功能,但从未遇到过问题。 I'm totally confused. 我很困惑。
Can anyone help??? 谁能帮忙???
In the first example, the last parameter (HKEY *) returns the new key. 在第一个示例中,最后一个参数(HKEY *)返回新密钥。 You must provide the variable (HKEY, not PHKEY) where RegOpenKeyEx should store the value, and pass its address: 您必须在RegOpenKeyEx应该存储值的位置提供变量(HKEY,而不是PHKEY),并传递其地址:
HKEY key = 0;
hResult = RegOpenKeyEx(...., &key);
The second call may have the same problem. 第二个电话可能有相同的问题。
