Problem while clicking link(Win Forms)

[Ganapatisb]

Hi Friends,

I have one win form where there is a one labellink. When i click on that link it opens pop up window in IE7 explorer. When you click on same link it opens another pop up tab in IE. But i have to avoid that. When you click on that link it should display same tab which is already opened instead of creating new tab. I have tried with

System.Diagnostics.Process proc

and i have written code like this

try

{ 

 if (proc.HasExited) 

{

proc =


Process.Start("iexplore.exe", "www.google.com"); 

}
 
else

{

MessageBox.Show("Window is Already Opened!!"); 
}

}
catch
{
proc = Process.Start("iexplore.exe","www.google.com");
}

But here the problem is when you close opened tab and keep another empty tab , click on that link it says that Message already opened.

I dont know how to solve this. Please give me solution if you know this..
Thanks in advance..
