• Mateusz Rajca Passing variables or objects?

  I am fairly new to programming in C# but I have been developing in T-SQL for some time. In SQL there is no such thing as objects so we pass everything with variables. I have seen sample C# code that passes data as a variable and other times as an object. My question is which one is better, for what reason and how would I know when to use one or the other. An example is below. Thanks for your help. Private void Sample1() { Int someInt; String someString; someInt = 1; someString = “test”; DoWork(someInt, someString); } Private void Sample2() { SomeObject someObject = new SomeObject(); someObject.someInt = 1; ...Show All

• sahady Writing to a file

  I am having trouble figuring out why I can't write to a file, but I can read from a file fine. I've tried a ton of different methods including StreamWriter file = new StreamWriter("file.txt", false); StreamWriter file = new StreamWriter("file.txt"); Each time the program runs fine, but no file is generated. Even if I create a new file in the folder and add it to the project it still does not write to the file. I have VS 2005, VS 2003, but right now I am using VS C# Express Edition. Thanks in advance for any help, maybe this is just a problem with my C# Express Edition. Here is an example that doesn't do anything.

• Ralf Abramowitsch MessageBox.Show()

  Hi all Can the default popup message box MessageBox.Show() be coerced to always show up in a certain location on the screen, rather than dead center Thanks Heinz Thanks sirjis , after reading the artice I will roll my own indeed. Probably, but I would definitely recommend against it. It would be much easier to make your own form that looks like a message box. If you're really set on using the canned MessageBox, take a look at http://www.utmag.com/wconnect/wc.dll 9,7,10,775 (the first good result I found, although I'm pretty sure I've seen some on codeproject before). ...Show All
