• Windows Forms How to do a new line return on a rich text field

  I am having a stupid issue with a Rich Text Field and needing to drop a new line programmatically. In writing to the Console, it is easy, just use "\n" to cause the string to the next line; well I am just wondering how I would do the same thing for a rich text box Say for example, I want to print 10 sentences out in a Rich Text Box. After each sentence I want to go to the next line so the sentence does not overwrite the previous; what can I do to achieve this for ( int i = 0; i < 10; i++) { RichTextBox.Text = "The brown fox ran fast"; //How can I get this to drop to the next line each time it is printed } Thanks, Flea for ( int i = 0; i < 10; i++) { RichTextB ...Show All

• .NET Development Memory consuming during BinaryFormatter Deserialization

  Hi, I have a problem and I need your help please, I have made a large aplication that takes a very long time to generate the results, so I have serialized the intermediate results periodically in a binary files using BinaryFormatter in order to save it from any suddenly problems like shutdown or restart.

• Visual C# Attributes

  I just wanted verification on this. If I use custom attributes to document bug fixes in my code, will that effect run-time performance [ BugFix("01/01/07", "Fixed problem with calculation...")] [BugFix("01/04/07", "Added error-handling....")] public void MyMethod() { ................ O'Reilly gives the Bug Fix as an example of using an Attribute, so i guess it is OK http://www.oreilly.com/catalog/progcsharp/chapter/ch18.html .

• Game Technologies: DirectX, XNA, XACT, etc. Starting work on my GUI system

  Well, I've hit a wall with my game's development, and since there was no GUI with XNA 1.0, I've decided to go ahead and make my own GUI system. I implemented a lot of mechanics for my game, but I need greater interaction to proceed development in a sane manner. So far I've just implemented the text drawing stuff from scratch. It uses only monospace fonts generated with BMFontGenerator without using the generated .xml file. It's decidedly minimal to use only monospace fonts, but keep in mind two things - 1) my particular game doesn't require anything more robust than monospace fonts and 2) a game's engine should be designed around the game's specifc requirements. Otherwise you're scope creepin. I remind myself constantly not to let cool ...Show All

• Visual C# dynamic asp button click doesn't work first time

  Hi all, I'm creating some asp buttons dynamicly and I associated them an event handler btnDel.Click += new EventHandler (btnDel_Click); but the first time I click on the button goes to the Page_load but the btnDel_Click is not fired. Somebody knows the reason Thanks in advance. P.D.: Sorry for my english. Hi all, I have solved this problem by changing the asp button to html button, and adding them an "id" instead of taking the .net one ("ctl_1", ...). I realized also, that the only the first button hadn't the click event associated the first time. Also, the others were taking the arguments of the previous button, i.e., the second button was taking the arguments of the first button, th ...Show All

• Visual Basic Call EXE method from DLL

  Hi Is there a way that I can call a method in an EXE (managed code, VB.NET) from a .NET DLL by passing a reference to the instance of the EXE Multiple instances of EXE might be running and loaded in memory and I need the DLL to invoke a method within the running instance by passing a reference (such as the application title, window handler etc). In case you are wondering why the DLL is calling the EXE method and not the other way around, it is because this DLL is like a wrapper class and the method that invokes the method in the EXE is actually called from an Access VBA module. TIA Oh. and I should probably mention...this is a clickonce app. I'm looking at using the StartupNextInstance handler, but it doesn't look to promising ...Show All

• .NET Development DataTable.Select() Question

  I've searched high and low for an answer to this, but all I can find is stuff about the filter/sort bug, so hopefully someone can help me. I want a distinct list of instruments where the date is the first date where the instrument has data. Ignore the possibility of null values. Normally I would write this is SQL: Select ValueDate, Instrument, Price where Instrument = '0001' and ValueDate = (select min(ValueDate) where Instrument = '0001') For some reason I just can't get this to work, no matter how many variations I use. I hope I'm missing something terribly obvious. Thanks in advance, James If you are using DataTable.Select(), you can simply achieve what you want by using strFilter = ...Show All
