I have a trouble writing some keys into registry:
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.
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.
I have also tried some variations, but the result is always the same. I was using this functions before and never had a problem. I'm totally confused.
Can anyone help???
In the first example, the last parameter (HKEY *) returns the new key. You must provide the variable (HKEY, not PHKEY) where RegOpenKeyEx should store the value, and pass its address:
HKEY key = 0; hResult = RegOpenKeyEx(...., &key);
The second call may have the same problem.
