I'm use c# (VS2010, dot net ver4.0 client profile).

Barcode.net version is 6.6.0

I was buy it at this week.

and I downloaded it 1st Dec. 2014. ( a few days ago. )

first of all, Review simple code.

--------- Begin my CODE -----------------

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using Aspose.BarCode;
using Aspose.BarCodeRecognition;

namespace BarcodeReader
{
public partial class cBarcodeReader : Form
{
cBarcode myBar;
public cBarcodeReader()
{
InitializeComponent();
myBar = new cBarcode();
MessageBox.Show(myBar.GetBarcode(@"D:\barcode\TestImg.bmp"));
this.Close ();
}
}

class cBarcode {
public cBarcode() {
Aspose.BarCode.License lic = new Aspose.BarCode.License();
lic.SetLicense(@"D:\barcode\Aspose.BarCode.lic");
}
public string GetBarcode(string filename) {
string ret = "";

BarCodeReader br = new BarCodeReader(filename, BarCodeReadType.Code128 |
BarCodeReadType.DeutschePostIdentcode |
BarCodeReadType.DeutschePostLeitcode |
BarCodeReadType.QR);
if (br.Read()) ret = br.GetCodeText(); // get only first code/
br.Close();
return ret;
}
}
}
--------- Finish my CODE -----------------

when I run this code (both debug and release mode). I got a InvalidOperationException at br.Read().

I don't know why.

That means
You tested my code and You also got same exception, right?

I think, It takes a few days or a few weeks for bug fixing...
I can wait but my boss and client do not wait...

So please tell me older version's URL that runs nomally.

I will make program older version until You Release bug-fix version.

Please....

Good bye..
Have a nice week end..
(maybe I work hole weekend... T.T )

Hi Jiyoung,


In addition to the above reply, please note that the DLL file stored in net2.0_Compact folder, is compiled on .NET Framework 2.0 compact version, which works perfect on the .NET Framework versions greater than or equal to 2.0. You may use this DLL (Aspose.Diagram.dll file in NET2.0_Compact folder). We have tested your sample code against the .NET 2.0 Compact DLL. We can recognize this barcode image correctly as follows:

[.NET, C#]
BarCodeReader reader = new BarCodeReader(@“C:\temp\TestImg.bmp”, BarCodeReadType.Code128 |
BarCodeReadType.DeutschePostIdentcode |
BarCodeReadType.DeutschePostLeitcode |
BarCodeReadType.QR);
while (reader.Read())
{
Console.WriteLine("Type: " + reader.GetReadType() + " Code Text: " + reader.GetCodeText());
}

Result:
Type: Interleaved2of5 Code Text: 00332940

We hope, this helps. Please let us know in case of further assistance or questions.
