Hi all,
Im baffled by some code Ive written and need some help.
I have a simple class which holds a property:
<br />
public class Person<br />
{<br />
private string myName = string.Empty;<br />
<br />
public string MyName<br />
{<br />
get { return myName; }<br />
set { myName = value; }<br />
}<br />
<br />
public Person(string name)<br />
{<br />
myName = name;<br />
}<br />
<br />
}<br />
And I have another class, which is pretty self explanatry:
<br />
public class Depoll<br />
{<br />
public static void NewName(Person obj, string newName)<br />
{<br />
obj.MyName = newName;<br />
}<br />
}<br />
And finally, here are my tests:
<br />
[Test]<br />
public void TestChangeName()<br />
{<br />
Person me = new Person("Andy");<br />
Depoll.NewName(me, "Bill");<br />
Assert.AreEqual("Bill", me.MyName);<br />
}<br />
I dont understand why my test passes.
When I provide the Depoll.NewName function with my object, I assume that Im passing an instance. Therefore, any change to that object, will not affect the original, unless the Depoll.NewName returns it.
The Depoll.NewName function doesnt return the object once its been changed, therefore my original object should still have a name property of "Andy".
Can anyone help explain this?
Regards
Andy

Yes, you are passing a reference to your Person object to the static NewName method - not a copy of it, which means any changes to the Person within the method are reflected outside themethod.

Ahaa yes, thankyou.
So the question is, how do I make a copy of it.
Because Person 2ndPerson = 1stPerson; doesnt work either.

No, because once again you are just assigning a reference.
You may like to look at the IClonable interface and therefore the Clone method if you really do want a copy.

Or, make the Person type a struct instead of a class.

Did you try using the NextSibling[^] property? Once you have reference to the <code>XmlNode</code> representing comm, just do
XmlNode nextNode = node.NextSibling;

Ok so this:
OdbcCommand read = new OdbcCommand("SELECT id, species FROM species");
should somehow return a list of all rows for these feilds.
This should be
'1' 'somehting else' <-- as in id=1 species=something else
Anyway, then i execute the reader:
OdbcDataReader reader = read.ExecuteReader(); <-- (is this what im supossed to do?)
and then im stuck, reader.Read(); returns a true or false depending on weather or not there was a result (reading from left to right, top to bottom). Rather than 'true' 'true' 'false' i want '1' 'something else' null.
How do i do that?

Aahh, i was so close. When it reads its doesn't read from right to left top to bottom, at reads the WHOLE row, and goes top to bottom.
The result i get thats stored in reader, is an array, so i need to go
Console.WriteLine( reader[0].ToString() );
And so on. Well im happy AWAY!..

Hi,
Quite new to C# and Visual Studio, but here's my question..
I'm on a project that uses Windows Forms with a RichTextBox.
The text that is imported/typed in this box is copied to another RichTextBox, that eventually change this text to a Scrolling Text, from right to left on the screen. Searched the net for something like this, but I had no real luck finding it, except for the DougScrollingTextCtrl. Though this is not that user friendly in my opinion.
Is there anything I could think of to create something like this?
Thanks in advance.

Im not sure if this would be possile, but could you try using spaces?
Like this:
make a timer
-while(text doesn't go offscreen? <-- thats the bit im not sure about)
-text = " " + text;
then once it reaches t'other side, trim the first character for as long as it is " "
Then repeat, i don't have any code for this, its just an idea.

Thank you for the respond,
Thought about something like this as well, though this makes the screen flicker a bit, cause it's one char after another. Would like to see it smoothen out and for the user able to change the speed it scrolls. Said I used a RichTextBox, so the user can put text in there, but doesn't matter what control is used for the scrollingtext.
I'll be looking into it, cause it's a start anyways.
