RegDeleteKey
The RegDeleteKey function deletes a key and all its descendents.
Windows NT: The RegDeleteKey function deletes the specified key. This function cannot delete a key that
has subkeys.
LONG RegDeleteKey(
HKEY hKey,
| // handle of open key
| LPCTSTR lpSubKey
| // address of name of subkey to delete
| );
|
|
Parameters
hKey
Identifies a currently open key or any of the following predefined reserved
handle values:
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
The key specified by the lpSubKey parameter must be a subkey of the key identified by hKey.
lpSubKey
Points to a null-terminated string specifying the name of the key to delete.
This parameter cannot be NULL, and the specified key must not have subkeys.
Return Values
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value is a nonzero error code defined in
WINERROR.H. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic
description of the error.
Remarks
If the function succeeds, RegDeleteKey removes the specified key from the registry. The entire key, including all of
its values, is removed.
To open the key, use the RegCreateKeyEx or RegOpenKeyEx function. Do not use the RegCreateKey or RegOpenKey functions.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
