Yes, its true
But I want to do it through my code. When a user click a button I want to make a backup and so on 
I appreciate your help all the time...

use Microsoft.Win32.Registry and get the root RegistryKey which you want to backup. having this, loop recursibly over registryKey.GetSubKeyNames and get the corresponding values. now you can store this as xml.

Hello Everybody,
I have developed an application in which i have used Code 39 font and Embedded that in my application now whenever i run that application on XP that runs and give specified output.
Now when i tested it on Vista than i am unable to get the output in Code 39 font its just give output in normal font.

I haven't got a Vista box here at work to test on but it could depend on how you're getting the font. This is the method I use...
[DllImport("gdi32.dll")]
private static extern IntPtr AddFontMemResourceEx(
byte[] pbFont, int cbFont, IntPtr pdv, out uint pcFonts);
public Font GetEmbeddedFont(string name, float size)
{
PrivateFontCollection pfc = null;
Font fn = null;
if (null == pfc)
{
Stream stmFont = Assembly.GetExecutingAssembly().GetManifestResourceStream(
MethodBase.GetCurrentMethod().DeclaringType.Namespace + ".Resources." + name);
if (null != stmFont)
{
byte[] rgbyt = new Byte[stmFont.Length];
stmFont.Read(rgbyt, 0, rgbyt.Length);
uint cFonts;
AddFontMemResourceEx(
rgbyt, rgbyt.Length, IntPtr.Zero, out cFonts);
IntPtr pbyt = Marshal.AllocCoTaskMem(rgbyt.Length);
if (null != pbyt)
{
Marshal.Copy(rgbyt, 0, pbyt, rgbyt.Length);
pfc = new PrivateFontCollection();
pfc.AddMemoryFont(pbyt, rgbyt.Length);
Marshal.FreeCoTaskMem(pbyt);
}
}
}
if (null != pfc)
{
if (pfc.Families.Length > 0)
{
fn = new Font(pfc.Families[0], size);
}
}
return fn;
}
Then something like
label1.Font = GetEmbeddedFont("FRE3OF9X.TTF", 30);
If it doesn't work I'll have a play on Vista at home tonight.
Edit: Have tested the code above and it works fine on Vista 
Needs the following 'usings'
using System;
using System.Drawing;
using System.Drawing.Text;
using System.IO;
using System.Reflection;
using System.Runtime.InteropServices;

Hello Sir,
I have tried the solution that u gave me but it is not working ....
Before using your solution i was using this one....
class PrivateFonts
{
[DllImport("Gdi32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)]
private static extern IntPtr AddFontMemResourceEx(IntPtr pbFont, int cbFont, int pdv, ref int pcFonts);
public System.Drawing.Text.PrivateFontCollection GetFont(string[] FontResource)
{
//Get the namespace of the application
string NameSpc = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString();
System.IO.Stream FntStrm;
System.Drawing.Text.PrivateFontCollection FntNc = new System.Drawing.Text.PrivateFontCollection();
int i;
for (i = 0; i <= FontResource.GetUpperBound(0); i++)
{
//Get the resource stream area where the font is located
FntStrm = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(NameSpc + "." + FontResource[i]);
//Load the font off the stream into a byte array
byte[] ByteStrm = new byte[(int)FntStrm.Length + 1];
FntStrm.Read(ByteStrm, 0, Convert.ToInt32((int)FntStrm.Length));
//Allocate some memory on the global heap
IntPtr FntPtr = System.Runtime.InteropServices.Marshal.AllocHGlobal(System.Runtime.InteropServices.Marshal.SizeOf(typeof(byte)) * ByteStrm.Length);
//Copy the byte array holding the font into the allocated memory.
System.Runtime.InteropServices.Marshal.Copy(ByteStrm, 0, FntPtr, ByteStrm.Length);
//Add the font to the PrivateFontCollection
FntNc.AddMemoryFont(FntPtr, ByteStrm.Length);
Int32 pcFonts;
pcFonts = 1;
AddFontMemResourceEx(FntPtr, ByteStrm.Length, 0, ref pcFonts);
//Free the memory
System.Runtime.InteropServices.Marshal.FreeHGlobal(FntPtr);
}
return FntNc;
}
}
<b>ON BUTTON CLICK</b>
//string[] fontNames = { "FRE3OF9X.TTF" };
//PrivateFonts privateFonts = new PrivateFonts();
//System.Drawing.Text.PrivateFontCollection FntNc = privateFonts.GetFont(fontNames);
//labelBarcode.Font = new Font(FntNc.Families[0], 12);
Can you tell me what modification i have to do to get this work on Vista
because its working nice on XP....
Thanks

I don't know why the code I supplied doesn't work for you - I thoroughly tested it on XP and Vista.
Anyway, your code has two problem lines (I'm not sure how you got it to work in XP!):
FntStrm = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(NameSpc + "." + FontResource[i]);
won't work as the font is stored in 'yournamespace'.Resources... so you should try
FntStrm = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(NameSpc + ".Resources." + FontResource[i]);
byte[] ByteStrm = new byte[(int)FntStrm.Length + 1];
Why the +1? Remove that and it'll work.
byte[] ByteStrm = new byte[(int)FntStrm.Length];

string NameSpc = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString();
I've just noticed the unnecccesary .ToString() on this line. It'll work with or without it, but the Name property is already a string so there's no need.

Hello, I am very very new in this field, and my boss ordered me to develop a program which reads from textboxes of other softwares and stores the data.
Now I know that windows handler will do that, but field to develop a strategy how to do that.
Any suggestion Please?

I think it will me more easy in C++
any how at first you have to get the window handler of the other application and than from that handler get the handler of other controls on the window.

hello friends,
i have some values displayed in a comboBox. the selected value is stored in a variable. now the logic is this that when a button is pressed, the saved value of the combo Box is to be displayed in the combo Box. how do i accomplish this?
i have tried adding the value through the 'Items' property. it adds the value into the combolist but doesn't display it directly.
reply soon plz.

You can simply say
comboBox.SelectedValue = Value; / comboBox.Value (in case it is a windows form)
(Assuming the value was already in the list)

Good Morning All
Am a vb.net Developer and i have been here for sometime, but on vb.net and SQl forums, its my first time in C# Forum. Am new to C#, i want to learn C# as well. i have done some C++ and Java academicaly but never used them for Professional purposes. so C# doesnt look strange to me. i have Books on C# and have Downloaded some good E-books on C#.The question i want to ask is OOP's related. In vb.net i separate my application in Tiers, i will have a DAL ---> BLL-->PL(Presentation Layer), i create functions that will return or manupilate data in the DAL and Call them from a BLL and again Call them from PL by creating an object of a class, to do that in vb, we add a reference to a Project, i have tried that in C# and its there. Now my Problem is like this. Lets say i have the following DAL Project in my Solution that has a class that looks like this
<br />
<br />
namespace DAL<br />
{<br />
public class DAL<br />
{<br />
<br />
<br />
string GetInfo()<br />
{<br />
string name = "Vuyiswa";<br />
<br />
return name ;<br />
<br />
}<br />
}<br />
}<br />
<br />
And another Project in BLL, that a class that looks like
<br />
namespace BLL<br />
{<br />
public class BLL : DAL <br />
{<br />
<br />
DAL.DAL objref = new DAL.DAL() ;<br />
<br />
<br />
string Fname;<br />
<br />
Fname = objref.Getinfo()
<br />
<br />
}<br />
}<br />
<br />
As you can see the BLL code is not Complete, i have created an object of a class and i have set a reference to a DAL Project and i have inherited from the DAL , but when i try to use the method of a DAL class from the DAL Project in the Code. i know in C# we have the Main method, lets say where methods and function are called used. Do i have to create a main function for every Project, as in this case, the project DAL will not execute those functions they will be executed from the BLL
What is the difference between the C# and Vb.net in that matter
Thanks

you don't have to inherit BLL from DAL
just add a reference of your DAL in your BLL and than declare a object of DAL class... and there you go..
but first confirm that DAL class functions have public access modifier.

Thanks man,
Look at thing
<br />
<br />
namespace DAL<br />
{<br />
public class DAL<br />
{<br />
<br />
<br />
public string GetInfo()<br />
{<br />
string Fname = "Vuyiswa";<br />
<br />
return Fname ;<br />
<br />
}<br />
}<br />
}<br />
<br />
And i have referenced it and see and never worried about inheritance, and try to call the DAL Functions like
<br />
namespace BLL<br />
{<br />
public class BLL<br />
{<br />
string Fname ;<br />
<br />
DAL.DAL objDAl = new DAL.DAL() ;<br />
<br />
objdal.GetInfo();<br />
<br />
<br />
}<br />
}<br />
<br />
From the Above Code, am Successfully creating an object of a class DAL and i want to call the DAL Function Getinfo() and the intelisense does not even popup to give me confidence that the object is realy referenced
to the DAL Class.
what is wrong that am doing?
Thanks

Is that a direct copy paste? Unlike VB, C# identifiers are case sensitive... objDAl and objdal are not the same thing
