• Windows Forms Problem with inherits form

  I am trying to modify my existing form to use a new base form. In my new base form, I have added the following property. <DefaultValue(False)> _ Public Property TrainingMode() As Boolean Get Return Me.trainingLabel.Visible End Get Set(ByVal value As Boolean) Me.trainingLabel.Visible = value End Set End Property I use the trainingLabel visibility to indicate whether my system is in training mode. In the base form designer view, I have set the trainingLabel.visible to false. The problem is those inherited form based on the previous base form will change the TrainingMode to true automatically after I rebuilt the base form. I don't know how to debug this problem. As all this happened during the design ti ...Show All

• Visual C# Close() & Dispose(): which one or both?

  In relation to ConnectionString property: shall I Close() it or Dispose() of it or both More generally for SqlConnection - the same question: what is the proper way SqlCommand give only a Dispose() option, I guess There is nothing to Close in there, right Thank you. I don't understand what do you want to do with the ConnectionString property. It's a string, you do not need/cannot Close/Dispose it. As for the SqlConnection: Quote from the MSDN docs for SqlConnection.Close(): " If the SqlConnection goes out of scope, it is not closed. Therefore, unless you have placed your code inside of a using statement, you must explicitly close the connection by calling Close or Dispose . They are functionally equivalent ...Show All

• Visual Studio 2008 (Pre-release) How to capture client's infomation on server process?

  Hi Eveyone, I have a wcf service runs on the server as a console application (sefthost). Currently, I have many clients connect to that service and all of them work very well. Now I try to improve my system a little bit by trying to capture client’s info whenever a client requests the service on the server to do something. Does anybody have any example or any ideal how to do this Thanks in advance. Jdang You'd have to add an application header on the client side and then read it on the server - there's no built in way to see where the client is connecting from. On the client, when sending the message, do something like: using ( OperationContextScope scope = new Operati ...Show All

• Visual Basic Date.Parse Can't Read "P" or "A" for "AM" or "PM"?

  I'm a bit baffled at something. The following code passes: Date.Parse("10 PM") But the following throws an exception: Date.Parse("10 P") I find this to be weird because in the ToString, the format string allows: Dim d as Date = #10:00:00 PM# Console.WriteLine(d.ToString("hh t")) That will output "10 P" It seems like a shortcoming that it can't process something that it can output so simply. Unless I'm missing something Why do they even include a single letter format if they don't recognize it as part of a valid time try with: Date .ParseExact( "10 P" , "hh t" , Globalization.CultureInfo.GetCultureInfo( "en-us" )) ...Show All

• Visual Studio Team System Tracking requirements, scenarios & tasks through iterations

  I think I know the answer to this question having read some of the answers on this forum...but I'd like to make sure I have this is clear in my mind. In the MSF for CMMI process there are requirements, scenarios and tasks (plus other work items). In a development there will be multiple iterations to develop various features of the system. I would like to be able to track a requirement to its implementation in one or more of the iterations. I'm assuming that I would analyse the requirements to create scenarios and link them together (e.g. "customer creates wibble" and "customer views wibble history" being two scenarios that fufil the "customer's can manage their wibbling" requirement).
