Ok but, remoteEndPoint gives me where to connect,
The Problem is;
There is a Server which is justs listens a port, and a unknown client connects to port. Server wants to detect its IP, How this Could be possible?
Thank you very much for your interest!!

Your server would surely have some sort of an Accept() method that returns a Socket? You just use that Socket's RemoteEndPoint property

Hi,
My requirement is like I have to create control at run time by reading Control definition from XML file.
I have achived to read control from XML file create it dynamically.
Problem is I have to define hundreds of controls, is there any tool avalable to convert Controls(like textbox, button, ComboBox,..etc) in to xml file.
I mean to say properties of Control should be the attributes of a Control element in XML file.
Please help me in this regard ASAP.
Thanks
Zaheer

Why dont you create serializable versions of the controls you need and simply push them through an XMLSerializer?

Thanks for your reply.
But its not Possible to XMLSerialize a Control(TextBox).
How to Do that. Do you have code to do that.
Thanks

Hi!
First- sorry for the stupid subject... I just could't find something, that covers my question in a few simple words 
I'm writing a little application, where I want to be noticed, when the mouse leaves my window.
Because the window has no border, is non-rectangular (drawn vie GDI+) and nearly completly covered with controls (only a little circle right in the middle can be seen), I am not sure what is the best way of achieving this.
First, I could just look at the mouseMove event and check everytime if it left the region of my window...
I don't like that one much...
My second thought was to put something (an invisible control) on top of all controls- but this something has to let through all interactions with the other controls.
What is the best way to do this?
Second problem, perhaps it can be done with in the same way as the first- I need a hotspot on a button (again, shaped via GDI+), that fires an event if the mouse enters a sub-area of the button.
Can someone help me?
Thanks
Dirk

The second question is easy to solve. Handle mouse move and just do a check whether or not the cursor is in the subregion.
The first problem is kind of akward but there are serveral way of solving it. Probably the best way for you is to set up a timer and do frequent checks to see if the Cursor.Position is inside the region. Second is to use a globalhook and every time the mouse moves anywhere on the screen you check (not recommended, native code solution).

Hello!
How can I write shell extensions with C#? (more specifically: context menu items in explorer)
I'm looking for a nice tutorial like Michael Dunn's excellent article for MFC/C++[^], but using C#. I want to do some real shell programming, not just registry hacks[^]...
Thanks in advance and best regards
|

It depends which parts of the shell you want to extend, icon handlers and overlays are fairly simple while context menu extensions are rather more tricky. It all requires a reasonable amount of com and win32api interop and some fairly defensive programming to prevent errors reaching and crashing the shell if they occur. Some things like property sheets really aren't possible in fully managed code though that may change when the 2.0 CLR is released.

I use a panel draw images using graphics.DrawImage(image,x,y,imagewidth,imageheight). This method is called in a foreach loop so that i can fill the panel with different images.Each time panel is refreshed the entire loop executed so that more flickering on the panel.Is there any way to paint a region of a control?
please help!

For a simpler fix consider using double buffering. In the contorl ctor or somewhere else add this:
SetStyle(ControlStyles.DoubleBuffer, true);
A few other options there that you can mess with.

i 've used it, but itdoesn't make any big difference
thanx for ur reply

Although I'm not exactly sure what you are tyring to do... you can try using your own buffer by using an Image.

In case, you are using Invalidate method to refresh the Panel, then instead of using plain Invalidate method, use the following overload of this method, which will refresh a particular rectangular area only:
public void Invalidate(Rectangle rc);
Or, if possible, try to use some bool or other appropriate variable (defined outside the loop but used inside the loop) to somehow check as to in which circumstances and in what rectangular area, the Panel should be refreshed.
If you give details of the method or the manner in which you are refreshing the Panel, it may be possible to give some specific suggestion.

private void Panel_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Graphics g = e.Graphics;
if(myImageArray.Count > 0)
{
foreach (ImageClass myObject in myImageArray)
{
g.DrawImage((Bitmap)myObject.Image,myObject.TopX,myObject.TopY);
}
}
}
this is the code I used in Paint event of Panel
where "ImageClass" contain a bitmap object and its co codinates on the Panel.
"myImageArray" is an ArrayList of type "ImageClass".Each time I click on the panel,a constructor is created with image and Panel's (x,y) co ordinates and its added to myImageArray.
then refresh the Panel.

You'll want to use the Control's Invalidate(Rectangle rc) method (see MSDN[^])
panel.Invalidate(new Rectangle(0, 0, 100, 100));
Then when you paint the panel you only paint an image if its bounding rectangle intersects with the clip rectangle
protected override void OnPaint(PaintEventArgs e)<br />
{<br />
Rectange imageRect = new Rectangle(imageX, imageY, imageWidth, imageHeight);<br />
<br />
if (imageRect.IntersectsWith(e.ClipRectangle))<br />
{<br />
e.Graphics.DrawImage(image, imageRect);<br />
}<br />
}

I want that control (Label, TextBox) with property Enabled = false don't change it ForeColor to grey.
For example I have a UserControl with TextBox or Label on it. I can change TextBox property BackColor very easy:
private void UserControl1_EnabledChanged(object sender, System.EventArgs e)<br />
{<br />
if(this.Enabled)<br />
{<br />
}<br />
else<br />
{<br />
this.TextBox1.BackColor = System.Drawing.Color.White;<br />
}<br />
}
But I can't change TextBox(Label) property ForeColor!
private void UserControl1_EnabledChanged(object sender, System.EventArgs e)<br />
{<br />
if(this.Enabled)<br />
{<br />
this.BackColor = System.Drawing.Color.White;<br />
}<br />
else<br />
{<br />
this.textBox1.BackColor = System.Drawing.Color.White;<br />
this.textBox1.ForeColor = System.Drawing.Color.Black;<br />
<br />
this.Label1.ForeColor = System.Drawing.Color.Black;<br />
}<br />
}
This code can't do this!
If I make MyLabel by inheritance of Label and overide OnEnabledChanged(...), this will not help too:
protected override void OnEnabledChanged(EventArgs e)<br />
{<br />
}
If I put MyLabel on UserControl1 and then change Enable property of UserControl1 to false, the ForeColor property of MyLabel will not change!
But when I deactivate form with this control and then activate it, text of MyLabel will be grey.
Please, help!

In my humble opinion it is not wise to change the way disabled controls appear to the user. It can confuse people.
If you look into the Label implementation you will see that the disabled appearance of is hardcoded in. You cannot do anything about how a disabled Label looks.
However, if you really need to change something... create your own label implementation.

Some people have problems with monocrome LCD screens, where the text in textBoxes are almost invisible when they have Enabled set to false.
So actually it would be nice to be able to change that color...
Just a point of view.

Hello everyone,
I have a question on garbage collection that you guys will probably be able to answer in a snap. Here goes...
If I do this...
<br />
public void DoSomethingHere()<br />
{<br />
MyCustomClass mcc = new MyCustomClass();<br />
mcc.PerformFunction();<br />
<br />
mcc = new MyCustomClass();<br />
mcc.PerformAnotherFunction();<br />
}<br />
As you'll see above, mcc has performed a new twice. I'm just curious as to what happens to the memory from the first "new". Will the garbage collector know about it and clean it up later on, or is this considered a memory leak which will just sit in limbo?
Thanks,
~Brad

The garbage collector will pick it up - anything non-static that nobody has a reference to will be picked up.
