sorry ... I don't say correctly what I want
I want to send me a message if my button will be in the surface of the other buttons on the form

Iterate through all the existing buttons on the form, and check the coordinates against exist buttons. If any of the coordinates of the new button fall between the boundaries of another button, you have a positive.

is not there another way ... I mean I try this and is very much code to write. I think it must be another way to do that

What is so hard to comprehend? It's not a lot of code. You create a function to check coordinates. You call this function inside a for/foreach loop for each button in form controls property.

I can see this having no more than 10 lines of code.

that it was my solution before write to this forum .... and now is the same solution, but I think anyway it's to much for a simple check.
I'll do that and after that I'll check for another solution
thanks anyway

Rectangle r1 = new Rectangle(l1,t1,w1,h1);
Rectangle r2 = new Rectangle(l2,t2,w2,h2);

if (r2.IntersectsWith(r1))
return true;
else
return false;

where l1...h1,l2...h2 are the button x,y,width,height Big Grin | :-D

i created 2 forms in a project.
2 forms namely, form1 and form2.

form1 uses a linklabel control (System.Windows.Forms.LinkLabel) to open up form 2.

So when i click on this text "open form 2" which is the link label, it should open up the windows form2.

SOrry but i don't really know how to explain in much detail, hope the above helps abit...thanks!

I didn't know what you meant by "linked"

In the onclick event, just create an instance of the 2nd form and show it.

Simple...
just throw a link object on the form in the designer u know and double click on that, this will open the click event.
In taht click event just write your code as,

form2.ShowDialog(this);

private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    Form2 form2 = new Form2();

    form2.Show();
    //or
    form2.ShowDialog();
}

With form2.ShowDialog() form2 must be closed before any other window will be active, with form2.Show() you will be able to work in any window.
