RegistrySetValue Function

Overview

The RegistrySetValue function sets a value in a specific key location. If the key location does not exist, it is automatically created.

Syntax/Parameters

Syntax

int = RegistrySetValue ( string key, string name, mixed value );

Parameters

key

A string containing the name of the key to access.

name

A string containing the name of the value to access. If the value is an empty string, the default value for the key is set.

value

The value to set. This can be any type of data except handle.

Return Value

An int value as ERROR_NONE or a formatted error code on failure.

Remarks

With the exception of a char or byte list, the value as an array is not presently supported

The registry data type is set depending on the value parameter as follows:

	Legato Data Type		Definition (WinSDK)		Description
	boolean		REG_DWORD		Logical TRUE / FALSE.
	char		REG_BINARY		Always treated as binary array of bytes.
	byte		REG_BINARY		Always treated as binary array of bytes.
	string		REG_SZ		Treated as a zero-terminated string.
	short		REG_DWORD		Converted to 32-bit unsigned number.
	int		REG_DWORD		Converted to 32-bit unsigned number.
	long		REG_QWORD		Converted to 64-bit unsigned number.
	float		REG_QWORD		Converted to 64-bit unsigned number. The floating-point format must be maintained when reading back the value.
	word		REG_DWORD		Converted to 32-bit unsigned number.
	dword		REG_DWORD		32-bit unsigned number.
	qword		REG_QWORD		64-bit unsigned number.

 

If a literal is supplied used as the value:

	Implied Data Type		Definition (WinSDK)		Description
	Integer (32-bit)		REG_DWORD		If the high 32-bit portion is 0x00000000 or 0xFFFFFFFF, the value is truncated and converted to a dword. This allows truncation of both positive and negative numbers that will fit into the 32-bit form factor.
	Integer (64-bit)		REG_QWORD		If the high 32-bit portion is not 0x00000000 or 0xFFFFFFFF, the value is stored as a qword.
	String (“data”)		REG_SZ		Treated as a zero-terminated string.
	Floating-Point (3.14)		REG_QWORD		Converted to 64-bit unsigned number. The floating-point format must be maintained when reading back the value.
