Have a look a Request.ServerVariables Collection - It definately has the user's IP Address in there plus, I suspect, the other information you are after.

Use Request.UserHostAddress to return the client IP.
To get more info use Request.Browser

Hi there !
I want to store a list of System.Drawing.Rectangle objects in an ArrayList.
On action of user, the position of the Rectanlge objects should be changed.
Anyway, the collection is not updated when I use foreach in the Move function see below).
I guess the content of the arraylist is somehow protected, but what kind of dynamic list should I use instead ?
Thanks
ch
My code looks like this :
public class RectCollection
{
private ArrayList rects;
public RectCollection()
{
this.rects = new ArrayList();
}
public ArrayList Rects
{
get { return rects; }
set { rects = value; }
}
public void Add(Rectangle rect)
{
this.rects.Add(rect);
}
public void Move(int x, int y)
{
foreach (Rectangle rect in this.rects)
{
rect.Offset(x, y);
}
}

Its nothing to do with the list being "protected" from change - it is due to the nature of Rectangle. It is a value type, which means you effectively operate on a copy of it when calling Offset after it is unboxed from the ArrayList.
try this as your move method:
public void Move(int x, int y)
{
for(int i=0;i<this.rects.Count;i++)
{
Rectangle rect = (Rectangle)this.rects[i];
rect.Offset(x,y);
this.rects[i] = rect;
}
}

Hi to everyone,
I am writing a c# program that uses a native c++ dll. In the c++ dll I have a function which allocates space for a char array and returns it as follows:
char * my_func(size)<br />
{<br />
char * pOut = new char[size];<br />
...<br />
...<br />
return pOut;<br />
}
In C# part I wrapped the function as follows:
<br />
[DllImport("my_dll.dll", EntryPoint="my_func")]<br />
public static extern IntPtr my_func(int size);<br />
I am using the function in my code as follows:
<br />
IntPtr pData = my_func(nSize);<br />
byte[] arrByte = new byte[nSize];<br />
Marshal.Copy(pData, arrByte, 0, nSize);<br />
...<br />
The problem is how can I free the memory allocated in the native c++ dll by the new operator. 
Thanks

Hi
Are the optional parameters are allowed in C#. If yes how they r implemented?

Yes.
johnprakasht wrote: If yes how they r implemented?
It's a trick of the compiler.
Any other question?
I thought you might ask how to declare them! 
with the param keyword.
As in
Console.WriteLine(string format, params object[] arguments);
|
|
|
|
|
If you mean optional parameters like those in VB.Net: No you won't find this in C#. Generally just make overloads of a function with different parameter combinations.
|
|
|
|
|
Optional parameteres not allowed same as VB.net here.
way of implementation is that you must create oveloaded methods as below:
public GetTest(string str1)
{
....
}
public GetTest(string str1,string str2)
{
....
}

is .net framework necessary to run a c#.net app.
if have another way, plz help me.
|
|

You MUST read your previous "SAME" question.
The answer is NO.
That is the concept of C#.
If you don't want to use .NET Framework, then write your code
using old C++.

but i am not familiar with c++. plz can u give me any tutorial for me.thanks.

But sorry, I cannot tell you how to write a C++ code. Just find some books about that.

I'm wondering why Bill didn't implement document.selection for WebBrowser control in C# as it's the case for JavaScripts (http://msdn.microsoft.com/workshop/author/dhtml/reference/objects/obj_selection.asp).
How can I get the selected text of a WebBrowser now?
