    - window.close in javascript I'm writing an extension using ATL/COM. When clicking on the button, a new browser window with a form pops up, and when the form is submitted, the server returns a page to close the window using javascript window.close method. The pop up window is created through CoCreateInstance function, and thus when window.close is called from script, the browser prompts the user whether let the script close window or not. Yes we can set window.opener to null in ie6, but this no longer works in ie7. I tried to process the WindowClosing event, but it seems only be fired when the window being closed by script is created by script. I looked at del.icio.us's script in the pop up window, and found that they're just using one line: window.close(). What should I do to achieve the same effect as del.icio.us Any help is appreciated.

    - Wrap selection or IHTMLTxtRange in Font or Span tags of a given class I am trying to wrap the users selection (or a IHTMLTxtRange) with font or span tags that have a given class. The best that I can do now is: pRangeToRender.execCommand("BackColor", false, SOMECOLOR) I then use IHTMLElementCollection allEls = doc.getElementsByTagName("FONT"); and check each tag if it's SOMECOLOR. If it is, I clear the color and set the font tag's class. This is quite slow on large selection. Is there some better way to do it Tag: Internet Explorer Extension Development New BHO documentation site Internet Explorer Development

    - JavaScript Detect browser close IE 7 here is an alternate approach to running a script when a user leaves your site: - At the top of every script, set the session timeout to 20mins or use an application variable to set it to the IIS default. - Then, use the onunload or onbeforeunload events to call a script which sets the session timeout to one minute or so. - You then need to catch the session expiry event and call your log out code when it occurs. In ASP you can use the Session_OnEnd event in the global.asa. Thus, if the user is leaving the site (by closing the window, or navigating to another site), then his session expires one minute later. If he is only refreshing the page, then as soon as the page is called, the session timeout is reset to its normal value, and he stays logged in!

    - Type Mismatch JS error when adding Object attribute I am trying to build an Object element that holds a Flash movie by directly adding an element node to the DOM. For the most part it is working correctly, as the following code will create and display the Flash movie: ads_flashElement=document.createElement("object"); ads_flashElement.setAttribute("width", "600"); ads_flashElement.setAttribute("height", "250"); ads_flashElement.setAttribute("classid", "clsid 27CDB6E-AE6D-11cf-96B8-444553540000"); ads_flashElement.setAttribute("codebase", "http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"); ads_flashElement.setAttribute("movie", "mpuClipExpand.swf"); However when I add the "quality" attribute and try to set it to "high" I get a "Type Mismatch" JavaScript error in the browser. Why am I getting an error only on this attribute I realize that these attributes are usually included as PARAM tags within the OBJECT tag, but when trying to add PARAM tags as child nodes of the object I could not get the Flash Movie to display. I found I could add the movie filepath value as a direct attribute of the Object element. Is this the correct way to do it Is there a better way to feed the parameters into the Object element than by adding them as attributes of that node Tag: Internet Explorer Extension Development New BHO documentation site Internet Explorer Development

    - [IEDevTB] Toolbar Still Showing Page load Errors? A solution! Still want to use the IE Developer Toolbar and don't want to use the Firefox/Firebug combo Than I might have a solution for you, at least it worked for me! Rather than posting this message to various (unanswered) threads complaining about the latest IE Developer Toolbar showing a pop-up debugger window, I'd rather start a new thread. Problem in short: when you enable the toolbar IE generates an error almost on every page load making IE practically useless. You'll get messages like "Object doesn't support this property or method" followed by an error code. If you start up a debugger you will find a javascript line accessing the SetQuirksMode method in the ParseDoc function. On my system a screen pops up titled "Visual Studio Just-In-Time Debugger" giving me a choice which debugger to start. In my case I have a choice of 2: (1) New Instance of Microsoft Script Editor and (2) New Instance of Visual Studio 2005 My solution is really simple: just disable JIT debugging for these instances. That's it! How to disable it In case (1): Start the Microsoft Script Editor (part of Office 2003) (MSE7.exe) Select Tools/Options/Debugging Click on button 'JIT Settings...' and Uncheck 'Enable JIT debugging' In case (2): Start Visual Studio Select Tools/Options/Debugging/Just-In-Time Uncheck Just-In-Time Debugging Maybe you have different/more choices; just follow the same principle! Good luck! Tag: Internet Explorer Extension Development New BHO documentation site Internet Explorer Development

    - IE7 RC1 problem positioning pop-ups in pop-ups Can anyone tell me if the following behavior is by design or an IE7RC1 bug: If I call window.createPopup() where 'window' is in itself a popup window, the position of the second popup is limited - it appears that it should at least overlap 50% with the first popup. I use this mechanism in IE6 to create context menu rollover.. Any insight is much appreciated.. Casper -- to try this out, run this HTML in IE7RC1, click on tag, click on green -- <HTML> <HEAD> <TITLE>Nested popup windows</TITLE> <script> var firstPopupDiv = null; function tag_onclick() { var popup = window.createPopup(); var div = popup.document.createElement("DIV"); div.style.backgroundColor = "green"; div.style.width = 200; div.style.height = 200; div.onclick = div_onclick; popup.document.body.appendChild(div); firstPopupDiv = div; popup.show(30, 30, 200, 200, maindiv); } function div_onclick() { var popup = firstPopupDiv.ownerDocument.parentWindow.createPopup(); popup.document.body.style.backgroundColor = "red"; popup.show(230, 30, 200, 200, firstPopupDiv); // Not shown at 230! } </script> </HEAD> <BODY> <div id="maindiv" onclick="tag_onclick()">Click me</div> </BODY> </HTML> Tag: Internet Explorer Extension Development New BHO documentation site Internet Explorer Development

    - IE7 frames blank (intermittent, not rendered, disappear, empty body, XHTML) I am seeing a problem in IE7 and Firefox that is hard to reproduce. I have not been able to understand what is going on, and I am interested if anyone else has experienced the same kind of problem, or has any suggestions for a solution or how I should proceed with further diagnosis. If this post seems like an essay, I apologise. I am a developer working on a commercial web application being developed in classic ASP by a small company. Both in development and deployed it runs on IIS 6 (Server System 2003), in an intranet (sometimes through a VPN). I think all the dev and user clients are Win XP. The app has an intro page, that is a plain .htm, which links to the start page in a directory 'cgi-bin'. All pages in this directory are .asp. This start page is a frameset page, with three frames. The upper and lower 'menu' frames are set with fixed size; the middle 'main' one has all the remaining space ('*'). On IE7, the upper and lower 'menu' frames are blank. Using the Microsoft DevToolBar shows that their bodies are empty (the heads are populated as expected). Refeshing these frames causes them to display. This problem did not occur in IE6, and appears to occur indeterminately in IE7. On the other hand, in Firefox 1.5 the lower frame is consistently blank (reload does not cure it). Opera 9.1 displays all frames consistently. One factor appears to be our recent change to XHTML transitional throughout the app. A correct XML declaration, followed by a correct DTD, has been put on every page. Using frameset for the frameset page does not help, but removing the XML and DOCTYPE declarations altogether seems to make the problem go away in IE7 (but not in Firefox). All the pages use some Javascript, but there doesn't appear (to me) to be anything that explains what is going on, especially in the light of the (apparent) inconsistentcy of symptoms. Here is the essential code of the frameset page: < xml version="1.0" encoding="utf-8" > <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd "> <html xmlns=" http://www.w3.org/1999/xhtml " xml:lang="en" lang="en"> <head> <title>Censored</title> <link rel="stylesheet" href="../Styles/Styles_XP.css" media="all" type="text/css" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Cache-Control" content="no-cache" /> <meta http-equiv="expires" content="0" /> <meta http-equiv="Content-Style-Type" content="text/css" /> <script type="text/javascript" src="../javascript/JS_Code_Lib.js"></script> <script type="text/javascript" src="../javascript/Index.js"></script> </head> <frameset rows="51,*,28" frameborder="0" border="0" framespacing="0"> <frame name="Frame_Top_Menu" src="Test_Admin_Top_Menu_1.htm" scrolling="no" noresize="noresize" frameborder="0" framespacing="0"></frame> <frame name="Main" src="../cgi-bin/Logon.asp " scrolling="yes" frameborder="0" framespacing="0"></frame> <frame name="Frame_Bottom_Menu" src="Test_Admin_Bottom_Menu_1.htm" noresize="noresize" scrolling="no" frameborder="0" framespacing="0"></frame> <noframes> <body> <p>This page uses frames, but your browser doesn't support them.</p> </body> </noframes> </frameset> </html> This one page has the frameset DTD, all the others have the transitional DTD (all XHTML 1.0). I'm not going to post reams of code here. I'd be happy to post more code, or answer any questions, on request. If anyone can help me, I'd be extremely grateful.

    - IE 6/7 Cache-Control: no cache issues Related to Document download In order to prevent cahing on the client side, I send the following Http Headers: Cache-Control: no-cache Expires: -1 (As per documentation I read on MSDN). I have a Content-Disposition header set to "inline". When I stream back a document (PDF, Word, Excel etc.) IE 6 and 7 are not able to handle the response. IE 7.0 reports, "Navigation to the webpage was canceled". FireFox and Mozilla handle these documents just fine (with the same http headers). When IE 7.0 shows the "Navigation to the webpage was canceled" page it also shows a "Refresh the Page" link. When I click on this link I do see the document. If I remove the no-cache header or replace it with "private" or any other acceptable value IE 7.0 displays the document just fine. However, the browser will likely cache the documents in these cases. Changing the Content-Disposition header from "inline" to "attachment" doesn't change the end result (that is no document is seen or a document can NOT be saved) Looking at the Response being sent (using Fiddler) I can see that the document is being sent in the Http Content and looking at the task manager I can see Acrobat is being started. But no document. If the response sends back an xml document or image (with the two headers mentioned at the start of this post) IE 6/7 show the xml document or image as the case may be. Shiv.

    - MSDN Responsibility Doesn't anyone in the Passport group take some ownership for solving the Fatal Login Error. hr = 80041035, f = -2147217355 issue MSN really ruined my use of OE with their latest change to HTTP only. Finally got two systems back up and running (in good manner according tho them - in totally compromised manner according to me!). I am now on my wife's laptop and I keep getting the above message. I refuse to use OE on this system as me emails now download to what ever system connects with OE - it no longer holds my messages on the server until I pull it down to my desktop. I certainly don't need to have to police my emails over three systems, my laptop and desktop coordination is enough of a pain now that they have IMPROVED their email system. Hotmail on my wife's now gives my the above error. Total bodily waste product in my opinion. If MSN wants to change the way we do things, the very least they could do in to take responibility to correct errors associated with their control.

    - showModalDialog - displays white space at the bottom of the dialog I have dialog pages that are displayed with a grey background. They displayed fine in IE6 but in IE7 they show with a white space at the bottom that's approx. 20-22px high. Our app is used in a trusted zone in IE and we don't display the status bar at the bottom of the dialog and the IE7 dialog address bar is not displayed at the top. How would I get this to display correctly in both IE6 and IE7 I realize that I can probably get rid of the white space at the bottom by just stretching the background down farther but that will add blank space at the bottom of the window and make it look bad.

I had a lot of responses to my blog series on developing a BHO, so I've created a wiki guide too:
http://petesearch.com/wiki/

It currently contains a step-by-step guide to building a BHO, some articles on quirks and gotchas, and links to external sources of information. It's publicly editable, so anyone's welcome to correct any errors, or add articles.
