An issue I’ve come across a few times when adding an Add This button to any .net application is that the following error message is thrown:
The string 'fb:like:layout' contains too many device filters. There can be only one.
There’s something about the Highlander with that one, and it’s a bit irritating to say the least, but the fix is a simple one.
Today I was looking for a way to find a relative path between one absolute directory and another in C#. The .NET libraries themselves don’t seem to have anything that helps with this so I performed the obligatory Google search and came across a handy little function written by Peter Morris which I’ve now incorporated in my library.
The Background
Recently I was faced with the task of taking some existing VB.NET code and converting it to C#. Not so difficult so far you’ll say, and you’d be right. However, some of the code on this particular page was contained within a User Control which contained two lists of check boxes in two different categories, which for each category, when a check box item was clicked, was transferred via JavaScript to another (text) list for that category and the selected checkbox removed from the appropriate checkbox list.
