SQL server high availability comes in 2 basic categories. 1) Clustering using a SAN drive and multiple physical servers attached to the disk storage 2) Stand alone equipment acting in parallel A SAN configuration is an expensive solution; typically a disk storage array needs to be purchased with high speed communication channels (typically fibre). Therefore #2 is often the recommended configuration for smaller shops and less critical databases. Awareness of this topic is important for developers...

As a standard, we use ClickOnce to deploy all of our applications. I don't want to get into all the benefits as I have discussed some in a previous post. To summarize my scenario, I do software development for a 24 x 7 x 365 manufacturing plant. Our systems must always be online and we must provide after hours support. This week, one of our developers deployed an update to his end users. It was not until 7 PM that the end user determined there was a significant bug in the application that could cause...

I needed to find the version of .NET framework required for a vendor provided application in short order; there was no documentation (of course), the vendor was not available and the super user was not available. Your typical support scenario. When you try to run a .NET EXE on a computer that does not have the framework, your application informs you with a prompt along the lines of 'The Application Requires .NET framework version x.x' If you have the framework installed, it does not prompt you (of...
Recently I was working on an application that uses utilities provided by another DLL. The function I was using creates a custom connection manager based on the destination database. It seemed every time the connection manager was invoked, it would generate this error. A first chance exception of type 'System.InvalidOperationExc... occurred in System.dll A 'first chance exception' message notifies you there was an exception in one of your intervening layers. The exception was handled in the layer;...
April 30th Regina.NET and Regina IT Pro held the hereos community launch event. As far as I know, this was going to be the largest locally run (local speakers, facilities and sponsorship) IT community event. We booked 3 - 100 person classrooms and we had 3 speakers providing sessions that run concurrently, then repeated. The schedule looked like this Windows Server 2008; Room X SQL Server 2008; Room Y Visual Studio 2008; Room Z 6:30 AD, Hyper-V New Datatypes, Resource Governer LINQ, AJAX 7:30 AD,...
WoW, it took a couple weeks to get everything in order; but we are excited to be hosting Heroes Happen {Regina} April 30th in Regina, Sask, Canada. I worked with the local IT Pro user group to create this night of community run technology sessions. What is interesting, is that we are holding 3 sessions concurrently, then we are running the same session again so attendees can participate in 2 of our 3 sessions. They layout will look like this Windows Server 2008; Room X SQL Server 2008; Room Y Visual...
I spent a couple hours today installing Windows Server 2008 on my home server. I have to admit, this was the easiest and fastest Windows OS software install I *EVER* completed. My goal was to build a Windows 2008 Server as a VPC host using Hyper-V; I literally spent more time installing the Hyper-V Role than installing the Win2k8 OS (I suppose this is the benefit of Role based installations). Do yourself a favor and download this utility (http://www.grc.com/securab... to verify your BIOS is configured...
Currently my client has a number of WinForm applications in development. When it came time to deploy these solutions to end users in multiple facilities, discussions of xcopy installations started. Xcopy is not the best solution; in the past it has been servicable to meet this requirement, today we have better options. Some of the flaws of xcopy deployment include - Network connectivity required: if the PC is off it will not get the update - Installation Lists: You need to know which PC's have your...
