Embed Excel in web browser activex

Hi

Im embedding excel in web browser activex. This web browser im using in sdk form. I load a xls to the web browser. it is working fine. when i resize the sdk form, the form is resized and the web browser is also resized. what happens is the excel stops displaying. When i click on the web brwser activex, the xls is again displayed.

Can anyone help in resolving this. i want the xls sheet to be displayed even after resizing.

Thanks
