c# - Webbrowser dialog popup block -

i developing program has invisible web browser control used loading data web pages. however, having trouble blocking type of popup.

this code using block popups

private void webbrowser1_newwindow( object sender,                                      system.componentmodel.canceleventargs e) {   e.cancel = true; } 

i have tested on http://www.popuptest.com/ , fails block come & go test , modeless window test. http://i75.servimg.com/u/f75/13/13/40/49/b11.png

is there way block these popups?

this javascript shows popups

function modelesswin(url,mwidth,mheight){ if (document.all&&window.print) //if ie5     eval('window.showmodelessdialog(url,"","help:0;resizable:1;dialogwidth:'+mwidth+'px;dialogheight:'+mheight+'px")') else eval('window.open(url,"","width='+mwidth+'px,height='+mheight+'px,resizable=1,scrollbars=1")') }   modelesswin("http://www.popuptest.com/popup1.html",600,600) 

try implementing webbrowser feature control, particularly feature_block_input_prompts , feature_weboc_popupmanagement.

[edited] code works me test site, try (tested ie10). make sure set features before webbrowser gets created (before initializecomponent below) , scripterrorssuppressed = true suppress script errors caused blocked pop-ups.
