$15-25 AUD / hour

We have a very large billing system application with 200+ forms written in VB6. We intend to migrate this application to .NET over the next couple of years. The first step in this project is to convert the existing VB6 forms which currently invoke SQL via ODBC to invoking REST WebAPIs we have developed. The next step will be to convert the VB6 forms to .NET forms. This project will run for a number of years. We are looking for one or more experienced VB6 developers with some exposure to REST WebAPIs to work with us on this project. The initial task will be ; 1. We will give you the existing source code for one of the forms so you can understand the context of the project. Each form currently invokes a small number of stored procedures (4-6) to read and update the database. 2. We will give you a URL to the SwaggerHub specification of the web methods that you will use to replace the ODBC calls. 3. We require you to develop library functions to invoke GET, POST, PUT and DELETE REST methods from VB6. We use the ChilKat library and we would expect you to use this unless you can propose a better alternative. 4. We require you to integrate the library functions calling the REST methods into the source code of the existing VB6 forms we give you. Given the long term nature of this project are offering this project only on an hourly rate, anyone quoting a fixed price will be considered to be an auto-generated bid and be immediately rejected.

Hi, I have more experiences in Visual Basic 6 and MS SQL Server. I agree with you that it will take some time to upgrade as it using external DLLs or OCXs like (ChilKat library). We must first see the functions of these dlls, to make an equivalent or using it again in .NET .First step to check and analyzing VB6 code and take a general look will be the important one for me. So, I can start work with you as you described. I think i can help you in many things. We can discuss. Thanks.

Hello, I have read the job description and I can convert your vb6 app to .net as I have worked a lot on vb6, so it would be easy for me to understand the forms. Only after understanding the working of the forms one can convert them to .net. I have already created lot of application consuming web apis. I have 11 years experience in developing products using ASP.NET MVC, Azure, ASP.NET, C# Programming. Regards, Jai Singh
