Reference

In the following reference of all interfaces implemented, “Long” is defined as a 32-bit signed integer value,

and “Integer” is defined as a 16-bit signed integer value. “Byte” on the other hand is an 8-bit unsigned

integer value. “Single” is a single-precision floating-point number.

FireiPreviewControl

The FireiPreviewControl is a Windows.Forms.Control-derived control, which purpose is to show the video

output of the underlying API at work. It can be resized at will while running, and can be attached on any

Windows form.

FireiGUID

The FireiGUID object is a helper object, making the camera GUID easier to manipulate, store and retrieve.

It can be constructed directly, or through the SelectCamera method of FireiManager. It supports a

number of properties and methods through its interface:

[] property

Prototype

public byte this[int index]

Comments

The [] property is a read/write property, enabling the direct manipulation of any of the 8 bytes in a

FireiGUID object.

Visual Basic syntax

Dim Byte0 As Byte

Byte0 = Guid.Item(0)

'get

Guid.Item(0) = Byte0

'set

C# syntax

byte Byte0 = Guid[0];

//get

Guid[0] = Byte0;

//set

ToString method

Prototype

String ToString()

Comments

The ToString method converts and returns the bytes contained in the FireiGUID object to a regular

string, with each of the 8 bytes separated with the ‘:’ character for better clarity. Each byte is represented in

2-character hexadecimal form.

Visual Basic syntax

Dim StringGUID As String

StringGUID = Guid.ToString

1 2 ... 17 18 19 20 21 22 23 24 25 26 27 ... 94 95
