• Visual C# Aborting and Managing Threads: The Dog or the Cat?

  Newbie here .... thanks in advance for your patience. I'm working w/ C# Visual Studio 2005 I've read up on all the comments about problems w/ aborting and suspending/resuming threads.  Lots of things to consider.  Looks kinda ugly on all fronts.  Note that I'm not thinking of using suspend and resume to synchronize threads.  I would like to just pause and then restart a particular thread from where it left off.  Worst case is to abort the thread. I'm not using a ThreadPool.  This is because some of my operations may take a long time (long running database access routines), may require different prioriti ...Show All

• Visual Basic Problems with a CLASS

  Ok, here is my situation. I have created a class called “Calculations” in the main form of my project, I declare this class as   “Dim Calcs as New Calculations” and everything is fine and dandy, but In this same project I have another form where I also have to access the same class. So I do the same declaration to access the same class “Dim Calcs as New Calculations” For some reason other than I’m a rookie programmer wana-be , the values that I set while in a form other than the main form do not stay permanent, in other words, as soon as I exit that form, the value goes back to “0”. Can anyone help me on this one Thanks   W ...Show All

• Windows Forms A problem with databinding

  As I know, in the .NET Framework 1.1, if I bind a string property of a type to the Text property of a TextBox and when I change the Text of the TextBox in code, the string property doesn't get updated. Only if the Text is changed by UI action, for example, input some text into the TextBox , the string property will get updated. What I would like to know is in the .NET Framework 2.0, if I use BindingSource, Do I have the function of updating source automatically if I change the text of a TextBox in code. Thanks, Chester ...Show All

• .NET Development New System.Threading.Thread vs BeginInvoke

  Hi! I'm having the following dilemma on how to handle multi threaded operations. I have to handle the case of multiple of calls per second that must be executed asynchronously. Creating a new Threading.Thread object is a simple solution, however I dont think its the best choise, since thread creation and destruction overhead would be too much. Creating a delegate sub and calling BeginInvoke also creates a new thread. My Question: 1) Is there a difference in performance between the two methods 2) Do the two methods use a thread pool For instance, if 100 calls are made almost simultaneously, would 100 threads be created ThreadPool::Qu ...Show All

• Visual Studio Team System Missing Default Rules?

  Hi all, I'm new to using FxCop and have been trying it out over the last couple of days. Now that I'm getting more into using it I've noticed something strange. I expect it's just because I'm new to it and seem to be missing something but could someone please clarify this for me Why does the Rules list under the Rules tab in FxCop not match up with the Rules list on GotDotNet (Naming Rules and http://gotdotnet.com/team/libraries/FxCopRules/NamingRules.aspx) Specifically, under the Rules tab in the Naming Rules, there doesn't seem to be the rule: Parameter Names are Camel Cased. Is it part of one of the Rules listed under the tab It's ...Show All
