Class Library or Web Service

[Robby]

I have developed a "Class Library" and tested it in Windows.Forms app and all is OK, however when I try to use it in a Web Application I am getting strange results (Variables being cleared, events raised with wrong arguments...). Is it possible to use a "Class Library" in a Web Application or do I have to create the Class Library as a WebService?

Cheers, Robby

Hi Robby,

Thank you for using the community.

As I understand, the Class library can work in your windows application
project, but failed in the ASP.NET application. In fact, a Class library
can be used in an ASP.NET project. The main difference between window
application and web application is that web application may use a
particular account's permission to call the Class library. (A windows
application use your current log on account).

Therefore, I don't think it is necessary to convert your Class library to a
web service. You may try to create a simple Class library and test to see
if it can work with your web application. And then, add the code in the
original Class Library part by part to trouble shoot it.

Hope this help,

Thanks, I discovered my problem was that the compoennt was being re-initialised everytime I refreshed the page, therefore losing all previous information from textboxes etc.. So I tried putting my component in the Init event but that is also called numerous times. Can you direct me to a good example of using controls and ASP.NET..

Cheers, Robby

Hi Robby,

Did you mean the Web controls in ASP.NET? If so, you may refer this article:
