From everything I read the compiler doesn't create properties in the IL it creates, it creates a method for setting a value and a method for getting the value. In the java world using accessor methods in the code is the way things are done and it works fine. Apart from the syntax of setting or getting a property value from code, which may be a bit nicer than the method syntax and the fact that people should learn to behave themselves in get{} code (I once worked with someone who changed the selected index of a combo in a VB6 Property Get for a comboBox, great fun when putting watches on things) I can see no advantages in using properties over accessor methods. At the same time I can see problems like the inability of c# to create Property delegates (i'm talking well behaved ways here) encouraging me to use accessor methods.
Can anyone think of reason why I should use properties in my code? Do we just blindly do things this way because we always used them in VB or because the books teach it that way?

Hello,
One reason could be the user support over the designer (VisualStudio Designer).

Never worked with VB before, but I'm also a fan of properties.

I hadn't thought about that. I guess things like databinding use properties aswell.
Maybe if the compiler allowed you to use either Propertyname = value or set_Propertyname(value). That way the delegate problem would be solved without relying on c#'s underlying implementation and we would have the best of both worlds.

Its just eye candy - as you rightly state, under the hood the IL is a get_PropertyName() and set_PropertyName(value) method.
I use properties as I prefer the look of
int myValue = myObject.MyProperty
than
int myValue = myObject.GetMyProperty();

You don't have to use properties if you prefer not to. Virtually everybody does though, as they make code much easier to understand.

One small adavantage is you can do something like this:
MyStringProperty += " Concatenate this...";
for getters and setters this would be SetStringProperty(GetStringProperty() + " Concatenate this...");
Same for other type (int, double,...)

yes, it's throwing me exception.
I've implemented the sample application from this site only...
sample code is:
try{
//get the graph filter ready to render
OpenFileDialog ofg = new OpenFileDialog();
if (ofg.ShowDialog() == DialogResult.OK)
{
String fileName;
fileName = ofg.FileName;
graphBuilder.RenderFile(fileName);
Text = fileName;
//set the trackbar
isSeeking = (graphBuilder.CanSeekForward() == -1) &&
(graphBuilder.CanSeekBackward() == -1);
if (isSeeking)
trackBar1.Enabled = true;
else
trackBar1.Enabled = false;
trackBar1.Minimum = 0;
trackBar1.Maximum = (int)(graphBuilder.Duration * 100.0);
Text = fileName;
//prepare and set the video window
videoWin = graphBuilder as IVideoWindow;
videoWin.Owner = (int)panel1.Handle;
videoWin.WindowStyle = WS_CHILD | WS_CLIPSIBLINGS | WS_CLIPCHILDREN;
Rectangle rc = panel1.ClientRectangle;
videoWin.SetWindowPosition(0, 0, rc.Right, rc.Bottom);
mediaEvt.SetNotifyWindow((int)this.Handle, WM_GRAPHNOTIFY, 0);
//set the different values for controls
trackBar1.Value = 0;
minutes = (int)graphBuilder.Duration / 60;
seconds = (int)graphBuilder.Duration % 60;
statusBar1.Panels[0].Text = "Duration: " + minutes.ToString("D2")
+ ":m" + seconds.ToString("D2") + ":s";
graphState = State.Playing;
//start the playback
mediaCtrl.Run();
}
}
catch( Exception ) { Text = "Error loading file"; }

What i had done is as follows:
Create a user control.
i have written all the above code in this class.
and then created an object of this usercontrol in another form.
and called the Run method from that form.
it works perfect.
Thanks & Regards,
Pramod

I want to burn my database backup file to CD/RW programmatically.
Anybody have a nice and usefull code for this?
I googled much and found a sample, but i couldn't test it because my drive is Network shared CDWriter. So please notice below code :
<br />
objBurner = new IMAPI_CDBurner.CDBurnClass();<br />
.<br />
.<br />
string drive = @"f:\";<br />
objBurner.GetRecorderDriveLetter(drive, 4);<br />
sfRecorderDrive = drive;<br />
there is an error with drive letter, "f:\" which "f" is my map drive.
error is :
"Error HRESULT E_FAIL has been returned from a call to a COM component."
anyway...
I need help for burning file to cd.
Regards.

Microsoft released an object which allows you to burn data to cd. I gues it's named XpBurn or something..
