How to close a dialog in code?

So I'm making a eclipse plugin and I have a made my own dialog by extending the dialog class.

My dialog basically populates a treeview with data from a server. Sometimes the data cannot be populated (because the server is down) so my treeview is empty.

I have made another dialog appear reporting the error if I am unable to connect to the server. My problem is that I would like to close the initial dialog when I press ok in the error dialog.

I have not been able to find a good way to do this. I have tried setting setBlockOnOpen to false. I have tried calling cancelPressed. Neither of them have worked. I called them in the createDialogArea function.

Any Ideas on how I could get this to work?

It is basically user cancelling dialog. you need to invoke cancelPressed() so it will be consistent handling if you have any code that depends on returnCode

if(noDataLoaded){
    Display.getDefault().asyncExec(new Runnable() {

     public void run() {
        cancelPressed():
    }
    });
}

You need to do the close call after the dialog creation has finished. You can do this by using this code:

parent.getDisplay().asyncExec(new Runnable()
  {
    @Override
    public void run()
    {
      close();
    }
  });

in your createDialogArea method. However the dialog may appear briefly. It would be better to do your check before creating the dialog.
