  ************** JIT Debugging **************
  To enable just-in-time (JIT) debugging, the .config file for this
  application or computer (machine.config) must have the
  jitDebugging value set in the system.windows.forms section.
  The application must also be compiled with debugging
  enabled.
  
  For example:
  
  <configuration>
  <system.windows.forms jitDebugging="true" />
  </configuration>
  
  When JIT debugging is enabled, any unhandled exception
  will be sent to the JIT debugger registered on the computer
  rather than be handled by this dialog box.

  Yes you can as you can see on the documentation.
  
  Here is a little example:
  
  

  InternetSetCookie("http://msdn.microsoft.com", NULL, "TestData = Test; expires = Sat,06-Jan-2007 00:00:00 GMT");

  Can you be more specific on that please Maybe you could give me a small sample code, including the namespace that I have to use!
  Thanks!

  You can use p/invoke to use the methods from wininet.dll, here are the p/invoke declarations:
  
  

  [DllImport("wininet.dll", CharSet=CharSet.Auto, SetLastError=true)] public static extern bool InternetGetCookie( string lpszUrlName, string lpszCookieName, StringBuilder lpszCookieData, [MarshalAs(UnmanagedType.U4)] ref int lpdwSize ); [DllImport("wininet.dll", CharSet=CharSet.Auto, SetLastError=true)] public static extern bool InternetSetCookie( string lpszUrlName, string lpszCookieName, string lpszCookieData ); [DllImport("wininet.dll", CharSet=CharSet.Auto, SetLastError=true)] public static extern bool InternetSetOption( int hInternet, int dwOption, string lpBuffer, int dwBufferLength );

  
  
  - Call InternetGetCookies to retrieve all cookies in a process
  
  - Call InternetSetCookies to reset the session ( which will reset
  cookies in a process)
  
  usage:
  

  // 0 - means all internet handles in same process InternetSetOption(0,42,null,0);

  
  
  
  - IF you want to set cookies for the new instance Call
  InternetSetCookie function which will set cookies.
  
  One thing to note here is InternetGetCookie function will give you a
  list of all cookies seperated by ";" . you need to do a bit string
  parsing to get individual cookies and set.
  
  Don't forget to prefix your url's with "http://", otherwise the method will break.
  
  

  InternetSetCookie("http://msdn.microsoft.com","mycookie","val=1&flag=0");

  
  
  will set the cookie mycookie for entire msdn.microsoft.com domain.

  Thanks! You're really helping me. The local security settings won't allow me to place that cookie from the windows user control with InternetSetCookie. Do you know if I can handle that from my managed code
