.NET Development Finalizer thread semantic
In a previous post , I was describing a weird problem encountered within the finalizer thread. Basically, within a finalizer I was doing quite a lot of work (complicated side effects, not simply cleaning few ressources), and I did encounter some weird CLR behavior. I am actually wondering about the semantic of the finalizer thread. First, I guess that intercepting the finalizer thread to do any real work is a bad idea because it blocks the garbage collection from running. Therefore, I have opted, within my finalizer method, to queue the side-effect works in the ThreadPool. Now my finalizer is non blocking. Additionnaly the side effects are ...Show All
.NET Development String.Format 10.0000 to 10.00 but keep 10.0001
Hi, I'm getting doubles with 4 decimal places, however when the last two digits are 00, I want to format to .00 but if the 3rd or 4th decimal place contains a value different to 0 I want to leave the 4 decimal places. Is there an easy way to do this with String.Format or would I have to evaluate the values and use the appropriate string formatter Thanks, Tom The default number of decimal places for InvariantInfo is 2. So you have to change it.. See http://msdn2.microsoft.com/en-us/library/system.globalization.numberformatinfo.numberdecimaldigits.aspx ...Show All

SQL Server Implications of not using Buffer.SetEndOfRowset()
Hello, I have a script source component that has been working fine for a while now. I have just noticed that I neglected to call SetEndOfRowset() on it. I've added that in now but there doesn't seem to be any affect. It seems strange to me that NOT having that line previously didn't cause any problems. Why is that What are supposed to be the implications of not calling SetEndOfRowset() Just wondering... -Jamie Hi Jamie, The implication of not calling end of rowset is that the dataflow engine does not know that you are done adding rows to the output buffer and, therefore, the dataflow would never end.
