Help Needed

I am working on the legacy application built on VB.NET running on VS2010

Application is making reference to 2 DLLs . I have installed the ChemAxon JChem Suite for Excel version 6.1.2.731.

Below are the 2 DLLs i am looking for

ChemAxon.JChemExcel.OpenXml;

ChemAxon.NET.Base.Marvin;

 

Any help would greatly be appreciated.

Hi,

Hi Viktor,

Application is a legacy application and I am new to this applicatiopn. I can't disclose much of the application. 

I am trying to compile the application but I see the reference issue because below 2 DLLs are missing. I need your guidance to get these 2 DLLs to compile the project. There are no developers others than me. 

 

ChemAxon.JChemExcel.OpenXml;

ChemAxon.NET.Base.Marvin;

 

Thanks

 Hi Dhananjaya,

We made a lot of changes in version 6.1. We created a new module called JChemExcel.IO.API instead of JChemExcel.OpenXml. This new IO API provides functionality to read and write JChemExcel files and gives possibility to convert ISIS for Excel and ChemDraw for Excel files to JChem for Excel files. The latest version (6.3.1) can convert Accord for Excel workbooks as well.

We can handle with this API OpenXml-based files (e.g. XLSX, XLSM, etc.) and standard format workbooks (e.g. XLS, XLT, XLM, etc.) as well.

The 2nd DLL what you mentioned, ChemAxon.NET.Base.Marvin.dll, is new for me. Are you sure this is the exact name of the missing assembly? Otherwise, our DLLs are in the Global Assembly Cache (GAC). Try to find this DLL there.

Could you please describe for us the workflow what your code implements? Hopefully our IO API will be an appropriate tool for you.

 

Best regards,

Hi  Gergely,

Thanks for quick response. I can't make modifications at this time as this is legacy application. I am compiling the source and I can see the references missing in the project.

Its federal government and I can't disclose application flow. 

Can you help me with atleast 1 DLL which is ChemAxon.JChemExcel.OpenXml.

Thanks

Regards

 Hi,

 

I cannot give you JChemExcel.OpenXml DLL with version 6.1. Release v6.1 doesn't contain that DLL, we don't support that anymore. You have to change the used reference to JChemExcel.IO.API.dll and you have to update your code.

If you give us code snippet using the current solution we will try to help you to rewrite that.

Developer guide contains some information about this API:

 Hi,

 

Do you use MSI or EXE installer? Sometimes security problems can occur in MSI installers so please try the EXE instead.

Hi Gergely,

Thanks for your suggestion. I was able to install using .exe as per your suggestion.

Thanks
