During our company wide adoption to Office 365 we ran into a snag and although it was simple to overcome once we discovered the right steps, it was a challenge at the time. To help others with their migration from Exchange to Office 365 we have put together a few tips.

Torn between LLBLGen 3.0 and Entity Framework 4.0? Let Gama make the decision for you.

Guidance on planning for and implementing the Hosted Messaging and Collaboration Solution 3.5 (Consolidated Server Platform)

Once upon a time I was a Visual Studio 6.0 developer, and thankfully it was a long time ago. Before last week I thought most of my day to day toolset experience from that era was left in the past where it belonged. Nonetheless I found myself adding DDE inter-process communication support to an ActiveX control written in .NET and C# last week. This means marrying Windows 3.11 era functionality with Windows 7 platforms. I doubt most developers will ever need to climb this mountain and I would not be surprised to find out I was the last man on earth. Just in case DDE lives on until the next decade though, I present you this chronicling of our experience.

In order to make a web based component talk to a locally installed DDE server we had to build a signed user control in Visual Studio.NET 2008 that could speak DDE. If it is not signed it is a real PITA to even get the control to instantiate. Save yourself some time and sign the control. It is really easy to automate it in VS.NET 2008 too. Once the control is instantiated in the browser it needs to make some DDE calls. This means “unmanaged code”, since DDE only exists strictly for backwards compatibility as a set of Win32 API library calls. Remember this since we will need to take special steps to allow for this later.

With the release of Microsoft's ActiveX Security Update, websites containing Flash objects have been bombarded with the annoying message "Click to activate and use this control".  In this article, I talk about how to remove this annoying popup message.  Also, I talk about the challenges that I faced when implementing the fix on DotNetNuke websites.

Jason launches a new DotNetNuke 3.02.02 site only to find MailEnable Webmail (enterprise 2.11) is no longer working, and then comes up with a solution.

Suppose you need to make some DNN core changes to a DNN instance that is already in production.  Because the changes will be affecting the server-side code, you must migrate the DNN production instance back to your development environment where you will be able to re-compile the project after you have implemented the code changes.
