I don't know this DLL, but it seems an not initialized object. Why bot doing directly Barcodetxt:=Barcodeprovider.GetBarcode(Item."No.");

In the above code, Barcode and Barcodeprovider seems to be the same assembly.

Hi Javed,

can you try this as the first thing in your function?

IF ISCLEAR(Barcodeprovider) THEN CREATE(Barcodeprovider,TRUE,TRUE);

Hi Roberta ,

i tried using this but getting an error.

Type conversion is not possible because 1 of the operators contains an invalid type.

Automation := DotNet

OK

Try:

IF ISNULL(BarCodeProvider) THEN

BarCodeProvider := QRCodeProvider.QRCodeProvider; //This is the constructor that you have to check.

and then:

Barcodetxt:=BarCodeProvider.GetBarcode(Item."No.");

GetBarCodeProvider(VAR IBarCodeProvider : DotNet "Microsoft.Dynamics.Nav.MX.BarcodeProviders.IBarcodeProvider" RUNONCLIENT)

IF ISNULL(IBarCodeProvider) THEN

IBarCodeProvider := QRCodeProvider.QRCodeProvider;

QRCodeFileName := IBarCodeProvider.GetBarcode(QRCodeInput);

It is working for on client but when I run it from Job Queue getting a error

Microsoft Dynamics NAV Server attempted to issue a client callback to create a DotNet object: Microsoft.Dynamics.Nav.MX.Barcode Providers.QRCode Provider (CodeUnit 50024 QR Code Mgt.). Client callbacks are not supported on Microsoft Dynamics NAV Server.

If I set RUNINCLIENT No then getting Cannot serialize an instance of the following .NET Framework object: assembly Microsoft.Dynamics.Nav.MX, Version=9.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, type Microsoft.Dynamics.Nav.MX.Barcode "Providers." BARCode Provider. in navision

Could you suggest any solution for this?
