• jules_newbie Issue with ConsoleTraceListener and Web projects

  I'm writing a log system based on MS Enterprise Library logging solution, and I' trying to make use of the built in ConsoleTraceListener in .Net. Now, it basically works in windows environment, but doesn't work in a web environment. From what I understand this is because Cassini (the built in debug web server is VS2005) doesn't have a console you really can write to. That's all fair, but I really find it odd that you can write to the debug console with Trace.WriteLine(...), but calling base.WriteLine(...) (where base is ConsoleTraceListener) nothing shows up. Why is this happening I can't help to think that ConsoleTraceListener and Trace should use somewhat the same mechanics, but can't really pinpoint what the difference is. I'd like to u ...Show All

• HilliMonster What is "\n"? Any difference from "\r"?

  I know "\r" indicates a sentence break. Then what about "\n" HtmlText = HtmlText.Replace( "\r\n" , "\r" ); HtmlText = HtmlText.Replace( "\n" , "\r" ); HtmlText = HtmlText.Replace( "\r\r" , "<p>" ); HtmlText = HtmlText.Replace( "\r" , "<br>" ); In the above line, since "\r" is to changed into "<br>", why should not directly change "\n" and "\r\n"directly into "<br>" http://west-wind.com/weblog/posts/1499.aspx if you are asking why it does not automatically convert to <br>, its because its not an ...Show All

• airwalker2000 Sorting 'complex' objects...

  Hello all, Just say I have an arraylist of objects (all of the same type) and say these objects are 'Person' objects. So each person has instance variables. such as firstname, surname, etc. I wish to sort this arraylist of person object references by surname. What is the easiest way to do this Thank you Chris Hi, You need something like this: SomeFunc () { m_data . Clients . Sort ( CompareClientsByName ); m_data . Clients . Sort ( CompareClientsByAge ); } int CompareClientsByAge ( Client c1 , Client c2 ) { return c1 . Age - c2 . Age ; } int CompareClientsByName ( Client c1 , Client c2 ) { return c1 . Name .

• Chris Honcoop BYTE in a UNICODE world

  I am reading a binary file into a byte array. I need to spawn a process via ProcessStartInfo class and pass this byte array to this process via redirecting its stdin to my program. So far no problems. Unfortunately, the StreamWriter that is used to send input to the spawned process (the write () function of Process.StardardInput) is via a string and/or char which are both unicode (it actually has 20 overloaded functions for all kinds of data types but the two applicable to me are string and char []). The text I am tryinig to send to the program is decrypted messages in binary format which when translated from byte to unicode string or char[] is losing some of its high ASCII values (> 128). Is there a way to send a byte array (or a ...Show All

• katokay CS0012 (missing assembly reference) but assembly is referenced!

  The solution compiles fine, but when running I get a CS0012 error.  The supposed missing reference is indeed referenced.  This started occurring when added some implict operators...here's the scenerio: in namespace CompanyName.Whatever1 there is a class called X; in namespace CompanyName.Whatever2 there is also a class called X.  These two classes our highly coupled (purposefully) but *are* indeed seperate objects (let's not get into this design, it's a problem that's being addressed).  Anyway these two 'X' object have to be pretty interchangable so we're using implicit casting.  This is all fine and well, and again works fine, but now at runtime when you go to create an instance of Whatever1.X you get CS0012 ...Show All

• Jeff Williams Timer Question

  I have a form with 2 buttons on it. Click on each button will launch their own methods. Let's say they are: button1_click button2 _click Now I want to add a timer to my form, and at specified intervals I would like the timer to launch each method, but I would like it to be as if I had clicked the button at that time. The reason is that I use a backgroundWorker, and I need my progressBar to still be able to update. Thanks for any help, Russ Hi Russ, if you want to trigger the buttons' click event from code, try invoking their PerformClick() method: private void timer_Tick( object sender, EventArgs e) {     button1.PerformClick();     button2.PerformCli ...Show All

• PabloWablo Syncing data - locking a public property?

  Hi folks, I have a public property (generic Dictionary) which contains some instances of a custom class (myCustomObject). this custom object also has some aggregations which also has some more aggregations -> a tree heirachy.

• Andrew Mercer Use function from DLL file
