RegSetValueEx(key, valueName, reserved, type, value)
Stores data in the value field of an open registry key.
If this parameter is None or an empty string and the type parameter is the win32api.REG_SZ type, this function sets the same value the win32api::RegSetValue method would set.
|REG_BINARY||Binary data in any form.|
|REG_DWORD||A 32-bit number.|
|REG_DWORD_LITTLE_ENDIAN||A 32-bit number in little-endian format. This is equivalent to REG_DWORD.|
In little-endian format, a multi-byte value is stored in memory from the lowest byte (the little end) to the highest byte. For example, the value 0x12345678 is stored as (0x78 0x56 0x34 0x12) in little-endian format. Windows NT and Windows 95 are designed to run on little-endian computer architectures. A user may connect to computers that have big-endian architectures, such as some UNIX systems.
|REG_DWORD_BIG_ENDIAN||A 32-bit number in big-endian format. In big-endian format, a multi-byte value is stored in memory from the highest byte (the big end) to the lowest byte. For example, the value 0x12345678 is stored as (0x12 0x34 0x56 0x78) in big-endian format.|
|REG_EXPAND_SZ||A null-terminated string that contains unexpanded references to environment variables (for example, %PATH%). It will be a Unicode or ANSI string depending on whether you use the Unicode or ANSI functions.|
|REG_LINK||A Unicode symbolic link.|
|REG_MULTI_SZ||An array of null-terminated strings, terminated by two null characters.|
|REG_NONE||No defined value type.|
|REG_RESOURCE_LIST||A device-driver resource list.|
|REG_SZ||A null-terminated string. It will be a Unicode or ANSI string depending on whether you use the Unicode or ANSI functions|
CommentsThis method can also set additional value and type information for the specified key.
The key identified by the key parameter must have been opened with KEY_SET_VALUE access. To open the key, use the win32api::RegCreateKeyEx or win32api::RegOpenKeyEx methods.
Value lengths are limited by available memory. Long values (more than 2048 bytes) should be stored as files with the filenames stored in the configuration registry. This helps the registry perform efficiently.
The key identified by the key parameter must have been opened with KEY_SET_VALUE access.
