two questions regarding iframes

Hi people

I got 2 questions regarding the usage of frames:
1) How can I calculate the exact top-left coordinate of an iframe which is located in the screen? The top-left coordinate needs to be in relation to the entire screen.
2) Consider the following: Page A opens a modal window B using window.showModalDialog(). Page B contains an IFrame C which is used to interact with the server.
When IFrame C reloads, I would like page B to close and page A to reload automaticaly.
I tried the following in C's body tag:

Code:

<body onload="parent.opener.location.reload(true); parent.close();">

page B gets closed with no problem but I get a JavaScript error on the first line saying: 'parent.opener.location' is null or not an object.

I would appreciate any help in any of the questions.
regards

Question 1:
I think you can use style.offsetLeft/Top or style.offsetX/Y (don't remember which one but I could check later), it should return the correct coordinate. It might only return the coordinates relative to the frames parent element but then you just add its top-left coordinate to the ones you got etc...

Question 2:
You need to use window.opener instead of parent.

Oops, remove style. before offsetLeft/Top. Just remembered that they are not part of the element styles but simple attributes.
