Dear users,
I have the following XML:
<name>MyName</name>
<descr>MyDesc</descr>
So the serialisation in C# would be:
[XmlElement("name")]
public string Name
{
get { return name; }
set { name = value; }
}
[XmlElement("descr")]
public string Descr
{
get { return descr; }
set { descr = value; }
}
But what if I have this?
<name>MyName</name>
<descr pos="after" type="string">MyDesc</descr>
Is the above possible to be serialised?
Thank you very much.
Regards,
Steven

Thanks karkster.
I have looked actually. However, the best I could find is how to serialise this:
<descr pos="after" type="string" val="MyDesc" />
which is not what I want like this:
<descr pos="after" type="string">MyDesc</descr>

Hi,
Vsree wrote: i tried to draw a *.jpg image
what do you mean by drawing a jpg image? Do you want to draw pixel by pixel in your application and save as a jpg or do you want to display a jpg?

Actually i tried to load an JPEG image from file and set its pixel color to a new value and redraw it using Graphics object and save it in the file.
<br />
Color c;<br />
for ( int x=0; x<imgDefault.Width-1; x++ )<br />
{<br />
for ( int y=0; y<imgDefault.Height-1; y++ )<br />
{<br />
c = imgDefault.GetPixel( x, y );<br />
c = Color.FromArgb( c.ToArgb() + 100 );<br />
imgDefault.SetPixel( x, y, c );<br />
}<br />
}<br />
pe.Graphics.DrawImage( imgDefault, 0, 0 );<br />
I loaded a MRI Scan image of human brain and tried to do the above work,
which threw error as:"SetPixel is not supported by Indexed pixel format"
What does it mean?
Please help me

SetPixel doesn't work with images with indexed pixel format. Try copying your image to a new bitmap pixel by pixel and make your changes on that bitmap

Try this:
Image imgDefault;
Bitmap imgSaveForSetPixel = new Bitmap(imgDefault.Width, imgDefault.Height);
using (Graphics g = Graphics.FromImage(imgSaveForSetPixel)) {
g.DrawImageUnscaled(imgDefault, 0, 0);
}

hey guys, having a little trouble here...
what im trying to do is set focus to an Edit field on a different application... so im doing this, to test im using Spy++ to get the handle to a random field on a random application,
Handle: 2692780
SendMessage(hWnd, WM_SETFOCUS, IntPtr.Zero, null);
it doesnt seem to be working
ideally what i want is to bring focus to the entire process, and focus the control...
am i on the right track here?

Hi!
The documentation for WM_SETFOCUS states that this is a notification that's being sent to a window when it's receiving the focus, it doesn't actively set the focus!
How about using SetFocus()[^]?

You should use properties for this, e.g.,
public string Address
{
get
{
return this.address;
}
set
{
this.address = value;
}
}
Or, just for get.
public string Address
{
get
{
return this.address;
}
}

Hello Legolas,
Actually set & get both are keyword of C#.
You can use it when you define any property for class like...
class TimePeriod
{
private double seconds;
public double Hours
{
get { return seconds / 3600; }
set { seconds = value * 3600; }
}
}
You can get more help from here.

If you want to use get & set you have to use a Property. (Unless you are programming in Java which don't have get & set)
It seems like you have two options.
1. To have TWO methods FOR EACH property, of get and set, eg. string getName() { return this.name; } void setName(string NewName) { this.name = NewName; }
(Just like in Java)
2. You can use it as a Property (the easyer and more comfort one), eg.:
string Name
{
get { return this.name; }
set { this.name = value; }
}
and to use it in code:
string thisname = obj1.Name;
obj1.Name = "My New Name";
(You don't use the "()" in a Property)
You can learn a little bit more if you read a little about this chapter.
Hope I helped.
NaNg.

using System;
class Circle
{
public int X
{
get
{
return(x);
}
set
{
x = value;
// draw the object here.
}
}
int x;
}
class Test
{
public static void Main()
{
Circle c = new Circle();
c.X = 35;
}
}
In this code, the get or set accessor is called when the property X is referenced.

I am using Visual Studio 2003 and C# to develop a textbox user control. In the Properties Window of the Visual Studio Editor I have a few of the public properties that the developer can select to change how the user control is going to behave and/or look. Is it possible to have some properties not available on the Properties Window until the developer has selected a value? For example the background color. If I use an enumerator to give the following values for the background color: Default, Custom
In the properties window I would like the developer to be able to choose a color if he has chosen the Custom option, but not if he has chosen the Default option.
All help will be appreciated.
Thanks

I am trying to understand how to hook up some event handlers. Here is an analogy to my situation: I have an object tree that represents all passenger trains in a train station. It looks like this:
<br />
Station<br />
.....Trains<br />
.........Train_0<br />
..............Cars<br />
................Car_0<br />
...................Passengers<br />
..........................Passenger_0 <br />
..........................Passenger_1<br />
.........Train_1 <br />
..............etc...<br />
Each of these objects fire events (like when passengers board a car).
I have a Form where I want to display status of Trains, Cars, Passengers etc.
I need to attach the handlers in the Form, but must be done dynamically, and I have no clue.
For testing I tried this, but I get a runtime error if the collections are empty:
<br />
Station.Trains[1].Cars[5].CarsChanged += new CarsChangedEventHandler(Cars_Changed);<br />
I have spent a good bit of time searching for info. Any suggestions would most helpful. I'm guessing that C# has an elegant solution (in lieu of my duck tape).
Thanks in advance-

Of course you get an error when the collection is empty, but that has nothing to do with event handlers.
You're trying to access Car number 5 when there is no Car number 5 in the collection if it's empty.
An event is usually bound to an instance of an object (there are static events, too, but they're far less common) and unless you have the instance you can't assign event handlers to it.

Hi
Well if you have a tree then you can enumarate it and hook up the event handlers:
Something like this:
<br />
foreach(Train train in this.trains)<br />
foreach(Car car in train.Cars)<br />
car.CarsChanged+=new CarsChangedEventHandler(Cars_Changed);<br />
if you are building the tree dynamically you can add the event handler on the fly for example
<br />
Car car=new Car();<br />
car.CarsChanged+=new CarsChangedEventHandler(Cars_Changed);<br />
this.SelectedTrain.AddCar(car);<br />
or
<br />
public Car AddNewCarToTrain(Train train)<br />
{<br />
Car car=new Car();<br />
train.Cars.Add(car);<br />
return car;<br />
}<br />
AddNewCarToTrain(this.selectedTrain).CarsChanged+=new CarsChangedEventHandler(Cars_Changed);<br />
Regards
