I often locate posts about Sage ERP ACCPAC. I found this blog post worthwhile.
With the Web UIs in Sage 300c rolling out in a couple of weeks, there is a lot of interest in the SDK and how to develop for this platform. We are still putting together the SDK, but in the meantime you can learn the technologies that are involved in developing our new Web UIs. Generally we’ve used off the shelf components both commercial and open source to develop our new UI framework. The good thing about this is that there are lots of resources available to learn the various technologies involved, including books, web sites, samples, videos, courses, etc.
We’ve generally tried to use all these tools in very standard ways. For instance we don’t add large amount of code to custom controls to change their behavior, we’ve kept it standard and only changed their appearance using CSS. We use the ASP.Net MVC framework in a natural way, so what you learn from the various standard resources is all applicable.
Due to the nature of programming, you can often do quite a few creative things. There is nothing to stop you using other libraries or tools than mentioned here. However one of the points of listing these is to let you know which we use, which means if you ask DPP support, these are the tools and libraries that we know about and can help answer questions about. You are welcome to use other tools, but we may not be able to provide much help on…
