Guid

Implements:

Public:

Properties:

Name	Description
Handle (get)	Returns a pointer to the internal GUID structure.
IsReadOnly (get)	Returns if the guid is read-only.

Methods:

Name	Description
CompareTo	Compares this guid to another.
Equals	Returns a boolean indicating if the value and this object instance are the same instance.
GetHashCode	Returns a pseudo-unique number identifying this instance.
ToByteArray	Returns the guid value has an array of bytes.
ToString	Returns a string representation of guid value.

Remarks

A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated.

A new Guid can be created using the NewGuid method or one of the factory methods in GuidStatic.

Note
The VBCorLib Guid conflicts with a hidden type in Visual Basic. In order to specify the VBCorLib version of Guid, a variable can be defined as CorLib.Guid instead of just Guid. Alternatively, moving the reference priority for the VBCorLib library above OLE Automation will give CorLib.Guid priority when a variable is declared.

Examples

The code parses a guid string then displays the guid in various formats.

Private Sub Main()
    Dim g As Guid
    
    Set g = Guid.Parse("{533217B3-CDEC-40A2-B01C-1EA8593B850F}")
    
    Debug.Print "Display guid with various formats."
    
    Debug.Print " D = " & g.ToString("D")
    Debug.Print " B = " & g.ToString("B")
    Debug.Print " P = " & g.ToString("P")
    Debug.Print " N = " & g.ToString("N")
    Debug.Print " X = " & g.ToString("X")
End Sub

' This code produces the following output.
'
'    Display guid with various formats.
'     D = 533217b3-cdec-40a2-b01c-1ea8593b850f
'     B = {533217b3-cdec-40a2-b01c-1ea8593b850f}
'     P = (533217b3-cdec-40a2-b01c-1ea8593b850f)
'     N = 533217b3cdec40a2b01c1ea8593b850f
'     X = {0x533217b3,0xcdec,0x40a2,{0xb0,0x1c,0x1e,0xa8,0x59,0x3b,0x85,0x0f}}
