What do you mean by "show" and "hide" desktop icons? What are you trying to do.

OK, I looked at it. Why on earth would you ever want to do this? If you modified my desktop like that, I'd uninstall your app before the last icon disappeared off the desktop. If you were locking down a desktop, you could do thie same thing through policies.

Use the win API function, ShowWindow and pass the handle to the desktop and 0 to the second parameter to hide the icons. 1 to show them again. Here's a sample console app.
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace ConsoleApplication14
{
class Program
{
[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
static void Main(string[] args)
{
IntPtr handle = new IntPtr(65722);
ShowWindow(handle, 0);
}
}

thx eggie5
ur code was very helpfull, i tried it , it works good , i got my dektop window handle from spy++ and but it the code
but i want to got the desktop window handle dynamically,
so i used the function "GetDesktopWindow" in "user32.dll"
but it didnt work , so i discovered that i have to get another window handle inside the desktop,
so i tried to use "EnumChildWindows" in "user32.dll" , but till now i still have problems to get the right window handle

That's a very reasonable request and I don't know why I didn't implement it in the first place. I must be a slacker. Anyways, to implement the "dynamic" desktop handle recovery you speak of, we need to introduce a new Window API function, FindWindow. Consider the following example:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace ConsoleApplication15
{
class Program
{
[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
[DllImport("user32.dll")]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
static void Main(string[] args)
{
IntPtr handle = FindWindow(null, "PROGRAM MANAGER");
ShowWindow(handle, 0);
}
}
}
We get the handle to the desktop by using a null parameter and "PROGRAM MANAGER" for the second parameter of the FindWindow function. Don't ask me how I figured it out. Anyways, that should work.
Additionally, if you have a "Show Desktop" button in your taskbar you will notice some cool clashing between your program and windows, because I think that "Show Desktop" button calls ShowWindow somewhere....
Let me know if this works for you...

thx again for ur help and interest

How an image is rotated at some sapcific angle?

Create a matrix and apply it to the Transform property on the graphics object.
Matrix matrix = new Matrix();
matrix.Rotate(45); // 45 Degrees
g.Transform = matrix;
// Now draw your image

Hint: Google is your friend
This concept may be alien to you, but people are not here to do your work for you, you need to put some effort in yourself too! You have been provided with a VERY helpful hint which answers your quention entirely. I understand you simply want to know what namespace to import. As I do not know this from memory I went to google and typed Matrix Class[^]. Lo and behold 4th result is the MSDN documentation - Matrix Class[^].
Im sure you can click on one of these links to find its namespace.

I have some old datafiles that need to be read at high speeds. They all use C strings and the file format can't be changed otherwise compatibility is lost with the closed source applications that write the files. How can I do this?
|

How can i transfer same format?
i send file on network but on client side not recieved same format.
i used Myobj class
[Serializable]
public class MyObject
{
public int size;
public byte[] buffer=null;
public string str="hello string";
public MyObject()
{
}
Server send data on network as
public void senddata(string fname)
{
MyObject obj=new MyObject();
//Create a file stream from an existing file.
FileInfo fi=new FileInfo(fname);
FileStream fs=fi.OpenRead();
//Read 100 bytes into an array from the specified file.
// int nBytes;
byte[] ByteArray=new byte[(int)fs.Length];
obj.size=(int)fs.Length;
obj.buffer=ByteArray;
IFormatter formatter = new BinaryFormatter();
formatter.Serialize(st.BaseStream, obj);
st.BaseStream.Flush();
}
& on client side receieved data as
public void receivedata()
{
MyObject obj=new MyObject();
IFormatter formatter = new BinaryFormatter();
obj =(MyObject)formatter.Deserialize(at.BaseStream);
Encoding ascii = Encoding.ASCII;
Encoding unicode = Encoding.Unicode;
byte[] ByteArray=new byte[obj.size];
byte[] asciiBytes = Encoding.Convert(ascii, unicode, obj.buffer);
// at.BaseStream.Read(ByteArray, 0, 11);
FileStream fs1=File.Create("c:\\clock1.avi");
fs1.Write(obj.buffer,0,obj.size);
fs1.Close();
ptr(obj.size.ToString());
ptr(obj.str);
}
kindly tell default encoding technique or any other solution
from which we receieve same format on server & client side
