Javascript to close an empty window

Hello I have a tricky situation, I am using MS reporting services from a asp.net web application and I render the report out as PDF in a new browser window. My problem is that the Acrobat would not launch (browser integration is disabled by MS by default and nothing much can be done about the open save cancel dialog box) in the browser. It opens its own instance of the reader and the report is rendered out but the window that I have opened also remain open. But if the same process is done twice(for example I open the report close the window and then open the report again the pdf file is openend in the browser window..)really weird!! So I am thinking is there a way that the new browser window be closed if NOTHING is rendered out and if after two tries the PDF is rendered out in the window then let it open. Another problem is when a PDF is rendered out in browser window, there is no source of the pdf file... So if someone has a solution please let me know. thanks in advance. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
