      • How would you match any sentence in a given text By "sentence", I mean something that begins with a capital letter and that ends with a point. I already composed this expression to match a sentence containing 5 to 50 words: "[A-Z]\w*(\s+\w+){5,50}\." But if you feed the sentence "Fruit e.g. apples are healthy for you.", then that regex only matches "Fruit e&qu

I see ADO.NET (connected model)allows updates, inserts, deletes only if you're grabbing data from a single SQL table, correct Why would you use a disconnected model It seems very restrictive and the data static, although less code intensive.

      • I'm having a tough time figuring out how to do this without resorting to logic outside the regex itself. I have a regex that gets rid of any characters except digits, and decimal points. The idea is to get a string that can be converted to a double. This works if there is one or fewer decimal points, but if there is more than one, it breaks. The replace gives me this: 1kjhkj2h
