• Windows Forms Public controls or not?

  I want to know that it will be a problem if i make the controls in my application public Because it's easier when they are public,but what are the disadvantages of this Cygnus This is a very subjective issue. If your application is a million lines of code, you don't want the global symbol table to have ten thousand variables in it, because it will slow things down a bit! If there is a lot of code re-use on your team, and you're building n-tier solutions a business object that requires a reference to a form that may or may not be there won't promote re-use. Seperating business rules & logic from the presentation seems like more work initially, but in the end it makes for a much more productive pro ...Show All

• Visual Studio Team System FxCop Microsoft.Design and Generic outputs

  Working on a deserialization loader mechanism, I started out with a public method signature which looked like this: public static T Load<T>( string filename) FxCop suggests: CA1004 : Microsoft.Design : Consider a design where YamlLoader.Load(String):T doesn't require an explicit type parameter in any call to it. I what it's suggesting is that invoking this method with code like this may be hard to understand because of the part in the angle-brackets below. Foo temp = YamlLoader.Load<Foo>( "temp.yaml" ); The only alternate design that seems obvious to me would be: public static void Load<T>( string filename, out T output) with calls looking like this: Foo ...Show All

• Visual Studio Express Editions format integer to XXX

  i have an integer field with maximum size of 3, that is "000". when user inputs a value that is less than 1000, i accept it and format it to a string like: 005,010, 025, 380, 669 is there a builtin function can do this in C#.net 2005 or i have to do it myself please help and be more specific in code Because it's typecasted as an object since the DataGrid has no idea what could be put in there. If you know that it is an integer you can actually type cast it as an integer. If it were a double or a decimal - same thing just have to use the specific type of data type. staff_noLabel2.Text = ((Int32) staff_no).ToString("000"); much more conscice. ...Show All

• .NET Development msmq Recieve problem

  We have encountered a problem with some .NET services (v2 - C# and VB) that make use of MSMQ. They (for no apparent reason, and no erorr messages) "terminate unexpectedly". It appears to be a call to MessageQueue.Receive that causes this to happen. Prior to this, several tens of thousands of messages had been processed successfully. There appear to be some hits on the web of a problem like this, but with no resolution. The services just stop. No graceful Exception handling or anything. Any ideas Thanks Tony Sounds like an unhandled exception. Add try/catch and log any exception you get to debug this. ...Show All

• Visual C# Time

  Okay, so I am trying to make an alarm clock program for computer, to familiarize myself with C#. What I need help with, is I have the dateTimePicker tool for setting the alarm, and I have a label for displaying the current time. My coding problem, as it were, is that I cannot figure out how to make the label display the current time, or how to get my program to play the music when the time comes around. I already have the ability to open a file, and have set the file filters for WAV, WMA, MP3, MP4, and MIDI files. so, my program can open files, but of course, at this moment, it cannot use them. Any help would be greatly appreciated. But using WMP SDK just adds extra bulk to something I can do with ...Show All

• Visual Studio 2008 (Pre-release) Dispatcher.BeginInvoke and application freeze

  Hi everybody, In my application, I use Dispatcher.BeginInvoke() to allow a long method to be run asynchronously. But this doesn't prevent my application to be freezed during the call of Dispatcher.BeginInvoke(): i click on a button which call the Dispatcher.BeginInvoke() method, but this button (and all of my app) is freezed and i've got to wait before being able to use my app again.... How can I launch a method asynchronously so even if it's a long method, I'm still able to use the app I tought Dispatcher.BeginInvoke() could do it but it looks like not.....

• Visual Studio Team System Project->Tasks: bogus start dates?

  So I have a fairly simple MSProject plan. I set up the tasks, assign to developers, input the work and get the calculated durations and, after leveling, start/end dates. All looks good in Project. Now I point it to a TFS project and do my Publish. All of a sudden, the Start dates for a handful of tasks get pushed out *months* from where they should be. For example, a task slated to begin in two weeks suddenly gets a start date of next May (even though the entire project is complete by this December). On the GANTT, you see a line drom the previous dependency vanish off way to the right. Funny thing is that I can Clear the leveling and re-level, and the dates in Project are right. But as soon as I Publish, they screw up again. Same tasks, di ...Show All
