How to Close external window?

Question

Hi Experts,
1) For one of the development requirements, I am required to open my application in
external window. For the same, I have changed the property of the iView  and page to
launch the iView in an external window and not to display in content area. Now, I am
able to display the application in a new window as per the requirement.
Now, I want to close this window from a button event on the screen, but can't find a way to close it.
If anyone's having an idea over it, that will be greatly appreciated???
2) Also, in another application, I am downloading data into excel sheet and the download
opens in a new window. Once the user clicks on the option (SAVE, OPEN, CLOSE),
the blank window should close which works well in IE 7 but in IE 6 the user says the blank
window is visible and they have to close it manually.
I am using the following code for this:
excelCSVFile = new FileInputStream(f);
IWDCachedWebResource cachedWebResource = null;
if (excelCSVFile!= null)
cachedWebResource = WDWebResource.getWebResource
excelCSVFile, WDWebResourceType.getWebResourceType(
"xls","application/ms-excel"));
cachedWebResource.setResourceName(fileName);
wdContext.currentVn_XL_SheetElement().setVa_Resource(cachedWebResource.getURL());
workbook.close();
* BEGIN: Open new window: download button
IWDWindow win =  wdThis.wdGetAPI().getComponent().getWindowManager().createExternalWindow
(cachedWebResource.getAbsoluteURL(),"Print Content",false);
win.setWindowSize(0,0);
win.removeWindowFeature(WDWindowFeature.ADDRESS_BAR);
win.removeWindowFeature(WDWindowFeature.MENU_BAR);
win.removeWindowFeature(WDWindowFeature.TOOL_BAR);
win.removeWindowFeature(WDWindowFeature.STATUS_BAR);
win.setWindowPosition(200,200);
win.show();
* END: Open new window: download button
For this if I try win.destroy() or win.close() or win.hide(), after win.show
this doesn't shows the download options at all (quite obviously   ).
I want to close this blank window automaticaaly once the user selects
any option for download. Is there any solution to this or am I doing something wrong?
Helpful answers will be appreciated. Thanks in advance.

Hi Gaurav,
If the external window contains the view of the wd component then only you can close the window.
Try like this:
Create a context attribute of IWDWindow in the calling view - component - called view and map them in all controllers.
//set the context attribute  in calling view
win.show();
wdContext.currentContextelement().setWinref(win);
* END: Open new window: download button
In onActionxxx event of the downlload button
// close the window
wdContext.currentContextelement().getWinref().destroyInstance();
