| | Re: methods You need to reread the requirements. Just looking at the first method you didn't implement what they asked. It should have two out parameters only, it doesn't do error checking. You've provided one out parameter and some other parameter that it didn't ask for. You only get one value in … |

| | Setting the name property at runtime doesn't affect the running code. It might affect reflection of the assembly, but I don't know why you would want to do that in the first place. Doing it in the designer just renames the control.  |
| | The first line of your program is probably [icode]static void Main(string[] args)[/icode]. args contains the command line arguments. |
| | Do you have references to the threads? If so, call Thread.Abort() on them. If not before you start the thread set it as a background thread (Thread.IsBackground = true). Background threads cannot prevent the main thread from closing (like your forground threads are doing). |

| | Have you verified that the SPTimer_Tick is firing at a constant rate? Have you checked if there is something in Serial_Data each time it fires but that there is no '\r' character in it? This might also be the problem (from the documentation): The DataReceived event is not guaranteed to … |

| | Since Access is a file based database (rather than a service based, like Oracle or SQL Server) your code needs direct access to the file. It needs to be on the same machine or a network share. As for [url]http://www.dofactory.com/Connect/Connect.aspx[/url], that site hasn't updated the Access connection strings in 4 … |

| | [code]for (int i = 0; i < 10000000; i++) { Font f = new Font(label1.Font.Name, 8, label1.Font.Style, label1.Font.Unit); }[/code] Fonts need to be disposed of when you aren't using them as they consume unmanaged resources. This should provide a small but growing memory leak. Code assumes you have a label … |

Ah, there it is, in the HtmlDocument.Title property (which you get through the WebBrowser.Document property). So something like … |
| | I really wish you'd use meaningful variable names. sortList# doesn't tell us anything about what it actually is. I'm guessing that sortList2 is actually a Dictionary and that the parts before the : are the key, after the : is the value. Do these keys actually have the () around … |
