Dear Dnn Guru,

I developed two modules from Christoc module develop template. I called them Module1 and Module2 here. I finished module1, its working well. Now I want to develop Module2. I would like using the data which stored in SQL Database by Module1 within Module2. So I import the namespace which built by Module1 and using the components and classes built in the Module1 namespace into my Module2. There is no error alert after I corrected any syntax problems. There is also no error alert after I compile the Module2 codes in Visual Studio 2017. I then install the Module2 into Dnn platform page and running the Module2. The page showed that the web controls are on the page but the data are not displayed in the controls. I check the Event View, there is no error info. So that I think if there is a logical problem prohibited displaying within the two modules communication, or other problems. In order to test if the Module2 can read the data stored by Module1, I copy the Module1 page web controls and backside page load codes and pasted into Module2, As said above I import the Module1 namespace(That means the codes in Module2 are same as Module1). I don't understand why Module2 is not working. Please help!

Best Regards

Jimmy

Are you getting the SQL data based on moduleID?
When you install module2 it will assign a different moduleID to the module.

Jimmy,

the better solution(s) could be:

1) Using the ModuleID of an instance of Module1 when querying data in Module2. You could store the module ID in the settings of Module2.

2) Using Inter-Module-Communication (IMC) - see http://dotnet-tech-guide.blogspot.com... (or google for that term)

3) Implement a web service that delivers the data from Module1 and is called by Module2. With that technique, Module2 could also be placed on a completeley different web site.

Happy DNNing!
Michael
