When developing using Visual Studio (VS) Microsoft recomends that you run VS with elevated permissions for debugging, for the most cases you really don’t need to do this but if you want to make it easier on yourself you can force VS to elevated permissions on the shortcut. Just right click on the shortcut and select Properties from the context menu then select the Compatibility Tab and check off the Run As Administrator check box as seen below. Now you probably want to turn off the UAC feature with this as well, this guide shows a few ways to do this.
That’s it.
Recently I was working on a web service that required logic than needed the span of time passed in months and days based on a start and end date. I figured someone has already written this before me so why waste my time. EPIC WRONG!!!!!! While I was able to find code (mostly snippets) that did various calculations most of them were either; a) not what I needed or b) fundamentally flawed in the calculations (most choked on month/day crossovers, where the as-of-date was 1 month previous and 1 day later than the sample start date). So I decided that I would take a chapter from the TimeSpan class and create my own AgeSpan class.
This class helps answers the question how many years, months, days, total months, total days from the birth date to the as-of-date. So for example on Mar 04 2009 this class tells me I am 40 years; 5 months and 1 day old or 485 total month or 14762 total days old.
One of the options available is to set the include as of date in the days calculation. What this does is include the as of date inclusively as part of the date range. Basically it adds one day to the days and total days. So taking the example from above I would be 40 years; 5 months and 2 days old or 485 total month or 14763 total days old. This option is set to false by default.
Included in the zip is a unit test project to validate the actual logic. The class is written in c# and it probably can be ported to VB pretty easily or just use the assembly as is.
