In Brazil we have a payment method called Boleto. There is a widely used COM/DCOM library called CobreBemX that is being deprecated by its vendor. We would like to create BoletoX, a substitute for this library. The main difference between CobreBemX and BoletoX will be that BoletoX will communicate with a RESTful API and the logic of Boleto's creation is on the server instead of on the library itself. We wanna keep the same interface of CobreBemX to make it easy to substitute one for another with minimum changes on the code. By same interface I mean, same classes, same methods, same properties, etc. So, an example of code of CobreBemX should run smoothly with BoletoX. BoletoX library should be a DLL and should work with all these languages: ASP, .NET, Access, C#, Clarion, Cobol, ColdFusion, Delphi, FiveWin, Java, PHP, Visual Basic, FoxPro, PowerBuilder, C++ Examples of code for each one can be viewed here: [login to view URL] For this job you don't need to worry about making the library run with all examples above, I highlighted them only to show the programming languages that it should work with. The only code that we want to do now are those written here: [login to view URL] So this code should work well. The same code is attached to this project.

I know COM/DCOM/OLE2 very well but i think for modern software environments its better to write a native code (PE EXE,AppX or something) instead of ActiveX solution. I can also make the required DLL however its no guarantee for binary compatibility for all requested languages since these languages may have different calling order for parameters etc etc. So its not that straightforward :) but for most of it possible.

Hello. I am interested in this project. If I have correctly understood the requirements, you want to create a new dll "BoletoX " which have same functionalities as its predecessor "CobreBemx". Few Questions 1. Do I have to develop Rest API too? Are you willing to provide me logic? Or I have to extract it from old dll? 2. I will be creating a dll in C# .Net. But I am not sure that it will be working with all technologies you have mentioned. However it should as .net binaries are windows binaries only. 3. I cannot estimate the project price and timelines now as I don't know about functionality of "CobreBemx". Will you mind to pass this on to me. 4. I am seeing that the github code you have shared is in Portuguese(non-english). So it can take some additional effort to first understand it into english :) Thanks
