RegSaveKey
The RegSaveKey function saves the specified key and all of its subkeys and values to a new
file.
LONG RegSaveKey(
HKEY hKey,
| // handle of key where save begins
| LPCTSTR lpFile,
| // address of filename to save to
| LPSECURITY_ATTRIBUTES lpSecurityAttributes
| // address of security structure
| );
|
|
Parameters
hKey
Specifies a handle of the key where the save operation is to begin, or any of
the following predefined reserved handle values:
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
lpFile
Points to a null-terminated string containing the name of the file in which
the specified key and subkeys are saved. This file cannot already exist. If this
filename includes an extension, it cannot be used on file allocation table
(FAT) file systems by the RegLoadKey, RegReplaceKey, or RegRestoreKey function.
lpSecurityAttributes
Windows NT: Pointer to a SECURITY_ATTRIBUTES structure that specifies a security descriptor for the new file. If lpSecurityAttributes is NULL, the file gets a default security descriptor.
Windows 95: This parameter is ignored.
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 hKey represents a key on a remote computer, the path described by lpFile is relative to the remote computer.
The RegSaveKey function saves only nonvolatile keys. It does not save volatile keys. A key
is made volatile or nonvolatile at its creation; see RegCreateKeyEx.
Windows NT: The calling process must have the SE_BACKUP_NAME privilege. For more
information about privileges, see Privileges.
Windows 95: Security privileges are not supported or required.

Nostalgia .Net |
|
.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 » |
