GetBarcode Method

In This Topic

Description

Returns the data for the barcode found at the specified index value within the array returned by AnalyzeDIB.

Syntax

Visual Basic
Public Sub GetBarcode( _ ByVal BarcodeNum As Integer _ )

Parameters

BarcodeNum: An integer value which represents the zero-based index number of the recognized barcode.

Remarks

Valid values are from 0 to NumBarcodes -1.

The GetBarcode method should be called after the AnalyzehDib or AnalyzeIPicture method has been called, and barcodes were found.

Since Barcode Xpress can return multiple barcode results from a single scan, the detected barcode results (both solved and unsolved, with solved barcodes ordered before unsolved barcodes) will be sorted using the following criteria:

First, the confidence factor is used to sort the barcode results from highest confidence to lowest.
Next, for any barcodes with the same confidence, they will then be sorted by their location, from top to bottom, then left to right.

Example

Example - GetBarcode Results in an array	Copy Code
'Sort the results top to bottom Dim BarcodeArray() As BarcodeInfo Redim BarcodeArray(0 To BarcodeXpress1.NumBarcodes - 1) ' fill the user type array For i = 0 To BarcodeXpress1.NumBarcodes - 1 BarcodeXpress1.GetBarcode i BarcodeArray(i).CodeName = BarcodeXpress1.BarcodeCodeName BarcodeArray(i).result = BarcodeXpress1.BarcodeResult BarcodeArray(i).CheckSumOK = BarcodeXpress1.CheckSumOK BarcodeArray(i).Confidence = BarcodeXpress1.Confidence BarcodeArray(i).Length = BarcodeXpress1.ResultLen BarcodeArray(i).X = BarcodeXpress1.BarcodeX BarcodeArray(i).Y = BarcodeXpress1.BarcodeY BarcodeArray(i).H = BarcodeXpress1.BarcodeH BarcodeArray(i).W = BarcodeXpress1.BarcodeW Next i ' actual sort results top to bottom Dim temp As BarcodeInfo For i = Ubound(BarcodeArray) - 1 To 0 Step -1 For j = 0 To i If BarcodeArray(j).Y > BarcodeArray(j + 1).Y Then temp = BarcodeArray(j + 1) BarcodeArray(j + 1) = BarcodeArray(j) BarcodeArray(j) = temp End If Next Next
