RegDeleteValue
The RegDeleteValue function removes a named value from the specified registry key.
LONG RegDeleteValue(
HKEY hKey,
| // handle of key
| LPCTSTR lpValueName
| // address of value name
| );
|
|
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
lpValueName
Points to a null-terminated string that names the value to remove. If this
parameter is NULL or points to an empty string, the value set by the RegSetValue function is removed.
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
The key identified by the hKey parameter must have been opened with KEY_SET_VALUE access (KEY_WRITE access
includes KEY_SET_VALUE access).

.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 » |
