Hello:
 
We are
working on a web application that load a DLL with reflection, with this DLL we are able to read barcodes.
In the
local environment everything works fine, this machine have windows XP proff. and an extended evaluation  version v15 of LeadTools.
 
When
we try the application in the development server (windows 2003 server), the
application gives the following ERROR when we call the read function:
 
Facade.m_oBarcodeEngine.Read(image, searchRect, BarcodeSearchTypeFlags.Barcode1dReadAnyType, BarcodeUnit.ScanlinesPerPixels, BarcodeReadFlags.None,0, bar1d, barRPdf, barColor);
 
In the development server, we have installed LeadTools
v14.5 full version in the HardDrive C:\, and the v15 version in the HardDrive
E:\, the application displays the following ERROR:
 

Leadtools.RasterException: Operation failed

   at
Leadtools.Barcode.BarcodeException.CheckErrorCode(Int32 code)

   at
Leadtools.Barcode.BarcodeEngine.Read(RasterImage image, Rectangle
searchRectangle, BarcodeSearchTypeFlags searchType, BarcodeUnit units,
BarcodeReadFlags flags, Int32 multipleMaxCount, Barcode1d code1d, BarcodeReadPdf codePdf, BarcodeColor codeColor)

   at
com.mapfre.general.sgdb.sti.Plugings.LeadToolsReadBarCodeLibrary.ManagerReadBarCode.SearchReadBarCode(InReadBarCodeDTO
inPluginOcrDto) in
C:\Trabajo\WorkSapce\Mapfre\MAPFRE_COMUN_STI\Solucion\LeadToolsReadBarCodeLibrary\ManagerReadBarCode.cs:line 78

 

The application need to work with
the v15 version, because we want to upgrade our current version.

 

We have done the validations with the same images on both machines.

 

 

Thanks.

Hello,

One possible cause of the problem is failing to find or load the LEADTOOLS barcode DLLs at runtime, possibly due to permissions issues.

I tired to check the project that you sent, but it uses some non-LEAD references that I don't have.
If you create a small working project that only uses LEADTOOLS references and demonstrates the problem, please send me the project so that I can investigate more about this issue. You can either post it here or email it to support@leadtools.com

Thanks,

Hello,

To resolve the problem, try to copy the following DLLs to the project
\bin\Debug folder:

Leadtools.Barcode.dll
Leadtools.Codecs.dll
Leadtools.Codecs.Fax.dll
Leadtools.Codecs.Tif.dll
leadtools.dll
Leadtools.ImageProcessing.Core.dll
Leadtools.ImageProcessing.Utilities.dll
Ltbar6r15u.dll
Ltbar6w15u.dll
Ltbar7r15u.dll
Ltbar7w15u.dll
Ltbar8r15u.dll
Ltbar8w15u.dll
Ltbar415u.dll

You can find these DLLs on the following folder on your machine:

I'm having the same issue. I've included all the above assemblies as references in my application and it persists.

What else do you suggest I look at? My code works locally.

To add a little background, my barcode search code is in a assembly with all the necessary references listed above. My main application calling this assembley unlocks 1d barcoding.

Does an operation failed only come from missing leadtools assemblies? Could it be a permission issue?

Hello,

What is the operating system that you use?

Do you face this issue on the development or the deployment machine?

Are you working on a web or windows application?

Try putting the ltbar*15u.dll files in the system32 folder.

Figured it out! The box that I deployed the application to had an expired version of Raster Imaging Pro. After uninstalling and reinstalling with a valid serial code it's working now.

There is no need to install the complete LEADTOOLS setup on the deployment machine. You just need to distribute the required LEADTOOLS DLLs on the deployment machine.
For more information, please see the help topic "Files to be Included with Your Application" in the LEADTOOLS documentation.
