When a user clicks on a tag in the tag_cloud he is redirected to the home page with all the instances of that tag, but for some reason the instances that fall under Habits are duplicating.

问题 I've got a function to add a tag by post ID, but now I would like to delete all the current tags for that ID before adding my new tags?

问题 I need to replace a matching pair of HTML tags by another tag.

Does anyone knows how to do that within a .NET 2.0 WinForm application? 回答1: ComboBox can autocomplete, but only one word at a time.
