    - Vista/IE7 spawns new windows when Office 2007 is installed (unlike Office XP) Thanks zhuangzl... Given that you opened Windows Explorer, I'm not sure how "open in same window" would relate to IE. It seems to be out of context for Windows explorer. The idea suggests that there would be an internet option which could be alterned to change this behavior. However, I don't seem to be able to find one in Vista/IE. Your solution appears to be for WinXP. Were you able to view Office 2007 files in WinXP IE7 or earlier Tag: Internet Explorer Extension Development How do I Build Browser Helper Objects in C# Internet Explorer Development

    - Custom Image Decode Filters for GIF and JPEG? Sorry for the very delayed follow up - I had stopped looking for a response once we had an acceptable workaround, but a "real" solution would still be preferable. The purpose of the custom decoder is to allow additional compression (the image will then be shipped across another (one assumes lower bandwidth) link, and then redisplayed there). For jpeg, the behavior is the moral equivalent of decoding as if the image had been compressed at a higher compression level (so that when the final display image is recompressed for transmission, it will compress better), but I don't personally know the actual mechanism used by the custom decoders. I don't remember off-hand what pwzUrl showed, but I believe it wasn't NULL in one case and non-NULL in the other or anything else that distinct, so short of parsing the value and making assumptions about what types of values are used when, this wasn't a promising line of attack. Like I said, what would be the best (cleanest) solution for us would be for IE to always look for a registered decoder and only look at its built-in list and use its built-in decoders if no external one was registered for that MIME type, but I'm open to any reliable ideas. ted Tag: Internet Explorer Extension Development How do I Build Browser Helper Objects in C# Internet Explorer Development

    - IE 7 Prompt for Cookies Hello, I'm currently working on a website and having a problem when Cookies are set to Prompt in IE7. What the application is doing is they are on a page a cookie is set (once they click Allow) then they redirect to a survey on another site, they fill out the survey and then are redirected back to my site. The Cookie expiry date is set to DateTime.MaxValue and yet it does not exist after the redirect. My guess is that once you leave your original site all cookies are deleted related to that site if you have Cookies set to Prompt. My questions is: Are cookies deleted after you leave the site they were created on if they in the settings Cookies are set to prompt Tag: Internet Explorer Extension Development How do I Build Browser Helper Objects in C# Internet Explorer Development

    - How to inject STYLE into a page (a final word) WARNING: This post contains inaccurate information. Please read follow-up post below. One final post on this subject. There are limitations and caveats to what you can do with a styleSheet object through script, namely: You can create a styleSheet , but you cannot delete one. The addRule method simply adds new rule; it doesn't update existing rules or merge rules under the same selector. You can retrieve objects from the styleSheets collection by ID; however, you can neither create a STYLE element with an ID, nor change the ID after the element is created. (The ID attribute is read-only on styleSheet objects!) Consider what happens when a page in a sub-frame adds a style rule to its parent page using a naive combination of createStyleSheet and addRule . Each time the sub-frame changed, it would add a duplicate rule to a new STYLE element. Since there's no easy way to detect whether the stylesheet has already been created, eventually IE returns a script error when it has had enough. Sub-optimal. If I started with a known quantity of style rules that were applied in all cases, I should only create the style sheet once. Fortunately, I can use TITLE to get around the limitations of the ID attribute. The following script retrieves a style sheet by title and creates a new styleSheet if necessary. function createCustomStyleSheet(t) { var ssa = document.styleSheets; for (var idx=0; idx<ssa.length; idx++) { if (ssa[idx].title == t) return ssa[idx]; } // not found, create one var ss = document.createStyleSheet(); // ADD RULES HERE ss.title = t; // instead of ID, which is read-only return ss; } Now, what if I wanted to remove rules dynamically Since I cannot delete the styleSheet object, I could simply remove each rule one at a time, like this: var cnt = ss.rules.length; while(cnt--) ss.removeRule(cnt); This is where things get a little tricky. There used to be a cross-domain scripting vulnerability in IE6 that allowed you to load any random file whether it parsed as CSS or not, and then read it with the rules collection or cssText property. As a result, IE7 has been patched in such a way that it causes script errors if you attempt to read from those properties. The following code works well in both IE6 and IE7. function clearSheet(ss) { var bAccessDenied = false; // This variation works on IE6 try { var cnt = ss.rules.length; while(cnt--) ss.removeRule(cnt); } catch(e) { // alert(e.description); if((e.number&0xffff) == 5) bAccessDenied = true; } // This variation works on IE7 if (bAccessDenied) { try { while(true) ss.removeRule(0); } catch(e) { // alert("No more rules."); } } return ss; } With these functions in place, I can now safely create and remove rules in a controlled way. var ss = createCustomStyleSheet("localStyle"); // unique ID clearStyleSheet(ss); // remove previously added rules ss.addRule('.myClass', 'background-color:blue!important;'); As you can see, inline styles via injected HTML are still quite a bit easier to manage. It's up to you to decide which approach to use. Tag: Internet Explorer Extension Development How do I Build Browser Helper Objects in C# Internet Explorer Development

    - registry entries for IE 64-bit toolbar Hi, On an off chance (1 in 10^40) your toolbar guid is already being used by another toolbar or activeX control that is being blocked by the IE ActiveX kill bit or the Addons Manager.

    - Side Search Bar shortcuts conflict with popup blocker in IE7 Hi, I have created a number of Side search bar shortcuts on my links toolbar to emulate the FireFox and Netscape Side Panel behaviour in IE7 and IE6. The shortcuts are in the form - [InternetShortcut] URL=javascript:window.open('http://search.ninemsn.com.au/spbasic.htm','_search');void(0); IconFile=C:\WINDOWS\SearchIcons.dll IconIndex=6 (copy and paste the above code snippet to notepad and then save as a url file type in your links folder) However I find that the shortcuts are not loaded if the popup blocker in IE7 is turned on (the side search bar displays a blank page) or if the current page is about:blank. The side search bar shortcuts work just fine in IE6 SP2, with third-party popup blockers turned on or from about:blank. Side Search bar shortcuts allows users of public browsers to choose their search provider(in their language) for side bar searching and extends the number of Explorer bars that can be loaded by IE browsers beyond the menu limit of 8 horizontal and 8 vertical. Please consider changing the popup blocker behaviour for links with target=_search in the next update release. Regards.

    - link target doesn't work from outlook when using IE7 We have an intranet application that has been running for about 6 years. It has worked flawlessly until IE7 came out. Most everything works except email links with a specific target defined. Pre-IE7 when a user received a notification regarding a customer, they could click the link in outlook and the site record would open up in the mainframe if the intranet applicatin was opened, otherwise it would create a new window and force the user to login. All of the target links contained in the pages launched by the main window work flawlessly, but it is as if IE doesn't allow targets to be used from any window outside the created application. Any help would be great. Tag: Internet Explorer Extension Development How do I Build Browser Helper Objects in C# Internet Explorer Development

    - IE7 div not stretching to fill width I keep getting this and I can't find the fix to it anywhere.... please help! When a div doesn't have enough content to fill the width of the area the div doesn't fill the whole width. A gap will appear at the end of the div in IE7 browsers. I don't want to have to set fixed widths for the middle content section so that it can shrink to fit re-sizing the browser. I've tried everything I can think of. Setting the width to 100% breaks it because the left navigation pane or right pane will no longer float. It's probably something really obvious so I can't find it on blogs. Floats, display states and random bug fixes I've found for IE7 don't seem to work. Thanks!!

    - IE7 and Windows Explorer Folder Hi, No. IE7 was designed to remove the shell from the web interface for security. There are HTA tools to access the shell from IE Command buttons and menus, but these open in their own window, not in a tab. There may be some third-party tools out there to give you a tabbed interface to the shell, Here's something interesting http://www.codeproject.com/cs/design/extensibleui.asp I would be wary on embarking on such an add-on, as you have to deal with issues of con-currency - updating all open windows and tabs when changes are made. There must be good reasons why MS has not done it yet. There are options on the Folder Options dialog. Shell Explorer>Tools>Folder Options to Open each folder in a new window or Open each folder in its own window. The IE7 Favorites center, in History View (Order by visited today) records all internet and local files that you visit. You can use this to navigate to shell windows that are viewing files that you have previously visited in the day. I would personally like to see a Windows menu added to IE7 like the third-party MSIE browsers like Maxthon etc. But then again this functionallity is already available with Task Bar Icon Groups.

    - IE6 & SSL/HTTPS (non-secure items) Hi, I have a strange behavior on my application using IE6. When accessing the site via HTTPS, everything is fine but when i mouseover my menu element (which is a simple <a> tag inside a <div>), i get the famous error: "This page contains both secure and nonsecure items. Do you want to display the nonsecure items " Now, of course, i have done my homework and searched the entire web for an answer. I have fixed/eliminated every potential risks such as: - IFrame Source - Image Request hardcoded to HTTP: - Ajax calls to HTTP Another thing i did is using Fiddler2. Bad news is, i don't see a single HTTP request going out. This is making me believe that i could be experiencing an IE bug...
