Hi all,

I created a custom module in VS 2008 Web Developer by creating a LinqToSQL data source in a new folder in the App_Code folder and and a new folder in DesktopModules with 2 Web User controls for view and settings and associated VB code. I compiled the module and "installed" using Host-->Module Definitions-->Create New Module, then added the controls to the definition. Everything works perfectly on our development site where I was writing the code in VS Web Developer. Again from the module definitons, I choose my module and clicked the "Create Package" button at the bottom of the definition page, select defaults, and the package is created. On our live site, I go to Host-->Module Definitions and select Install Module, choose the package I just created (with .zip extension), and click Next, and I receive the error: "A critical error has occurred. Object reference not set to an instance of an object." In the site's Event Viewer, the following message is displayed:

I'm pretty n00b at DNN, so I'm having trouble figuring out from the trace what the problem is. Any help would be greatly appreciated. If I can supply additional details, please let me know. By the way, both sites are v5.1.4 and running .NET 2.0

 

Thanks -Todd

I didni't include the source in the package the first time, so I went back and tried packaging and installing with the source. The package installed this time, but when I add an instance of the module to a page I get this error: "Exception has been thrown by the target of an invocation."

When I view the Event Viewer, this is what I see:

So it appears that the problems aren't going away. Any help would be great, thanks! -Todd

<p>When I opened the .dbml file in VS 2008 Web Developer, a message popped up to say that web.config did not have the correct data source settings and it would be updated from the .dbml data source. I also removed the data source in the layout manager for the dbml file and added it back in (not sure if that did anything). After that the module worked on the other site. I was able to do the same thing with two other modules.</p>
