Close dialog window on webpage

Question

I need to trigger some actions inside someone else's webpage. I have this code so far:

IHTMLElementCollection DeleteCollection = 
    (IHTMLElementCollection)myDoc.getElementsByTagName("a");

foreach (HTMLAnchorElement buttonDelete in DeleteCollection){
    if (buttonDelete.title != null && buttonDelete.title.StartsWith("Delete")){
        buttonDelete.click();
            // problem goes here
        myDoc.activeElement.click(); 
        SendKeys.Send("{ENTER}");
    }
}

This dialog pops up:

I tried myDoc.activeElement.click(); and SendKeys.Send("{ENTER}"); but the dialog seems to be out of the page, so I don't know how to trigger the OK button. How can I close the window?

You cannot close a browser dialog programatically. What you can do is hijack browser popup behavior. This might work for you:

window.confirm=function(){ return true; };
window.alert=function(){ return true; };
window.prompt=function(){ return "textOfMyChoice"; };

Basically, insert this javascript before clicking your buttons. If you want to later restore the popup behavior store them in another global variable.
