Hi all,

This is very strange.

The ".Net Configuration" - "RunTime Security Policy" - "Permission
Sets" used by my smart client includes all the permissions (not full
trust).

In the code, I notice that the call "if(HttpContext.Current == null)"
always throws a Security exception.

Ok, fine, then I don't call it.  BUT, the code would still throw an
exception even thought that line is not executed.  For example:

int i=0;
if(i > 10) {  // This block will never execute right?
  if(HttpContext.Current == null) {
     MessageBox.Show("It is null");
  }
}

It still throws an exception at "HttpContext.Current == null"!

BUT if I put "if(HttpContext.Current == null)" into another method, it
works fine.  For example:

int i=0;
if(i > 10) {  // This would work!
  if(CheckHttpContext()) {
     MessageBox.Show("It is null");
  }
}

public bool CheckHttpContext()
{
  return HttpContext.Current == null;
}

Isn't it strange?  By the way, does anyone know the different between
"Full Trust" and a Permission Sets that includes all the permission?

Thanks in advance!
