cruflbcs.dll: The COM object library (found in C:\Program Files (x86)\Common Files\Barcodesoft\Fontutil\).

Method 1: Late Binding

Best for version independence. No need to set references at compile time, though it runs slightly slower than early binding.

' Late Binding Example
Dim cruflBCSObj As Object
Set cruflBCSObj = CreateObject("cruflBCS.Aztec.1")

cruflBCSObj.SetCRLF(1)
cruflBCSObj.ECLevel = 23

Dim retval As String
retval = cruflBCSObj.Encode(strTemp)
' Apply BCSAztec font to retval

Method 2: Early Binding

Best for high performance. Requires adding a project reference to the cruflBCS.dll type library.

' Early Binding Example
' 1. Project > Add Reference > cruflBCS.dll
Dim obj As cruflBCS.CBcsAztec
Set obj = New cruflBCS.CBcsAztec

obj.ECLevel = 23
Dim qrcode As String
qrcode = obj.Encode(strToEncode)

Set obj = Nothing

Important: After calling the Encode method, you must apply the BCSAztec font typeface to the returned string in your UI (Label, TextBox, or Report) to render the barcode image.
