Changing the Toolbar Background in .NET framework

Paint Data Matrix 2d barcode in .NET framework Changing the Toolbar Background

You can customize the background you see on Internet Explorer's toolbar. It's just a bitmap. To change the background, create a REG_SZ value called BackBitmap in HKCU\Software\Microsoft\Internet Explorer\Toolbar. Set this value to the path and name of the bitmap file you want to see in the toolbar's background. Internet Explorer tiles the bitmap horizontally and vertically to fill the toolbar.

Search URLs are a convenient way to use different Internet search engines. For example, you might have a search URL called news that searches Google Groups. Type news Jerry Honeycutt in the address bar to automatically search Google Groups for all UseNet articles that contain the words Jerry and Honeycutt. HKCU\Software\Microsoft\Internet Explorer\SearchURL is where you create search URLs. If you don't see this subkey, create it. Then add a subkey for each search prefix you want to use. To use the example I just gave, create the subkey news. Set the default value of the prefix's subkey to the URL of the search engine. Use %s as a placeholder for the search string. Internet Explorer replaces 99

the %s with any text you type to the right of the prefix. Continue the example, and set it to http://groups.google.com/groups q=%s&hl=en. Add the REG_SZ values shown in Table 4 6 to the prefix key you created. The purpose of these values is to describe what to substitute for special characters in your search string, including a space, percent sign (%), ampersand (&), and plus sign (+). These characters have special meaning when submitting forms to Web sites, so you must substitute a plus sign for a space, for example, or %26 for an ampersand. Thus, the browser translates the string Ben & Jerry to Ben+%26+Jerry. Table 4 6: Values in Search URLs Name <space> % & + Data + %25 %26 %2B

Deriving the URL that you must use is easy. Open the search engine that you want to add to Internet Explorer's search URLs, and then search for something. When the browser displays the results, copy the URL from the address bar, replacing your search word with a %s. For example, after searching Google Groups for sample, the resulting URL is http://groups.google.com/groups q=sample&hl=en. Replace the word sample with %s to get http://groups.google.com/groups q=%s&hl=en. This hack is so useful that I have a script that automatically creates search URLs for the search engines I use most often. Copy the following listing to the file Search.inf, right click it, and then click Install. You can remove this script and all its settings using Add Or Remove Programs. This script creates search URLs for the five search engines that I use most often. The search URL news searches Google Groups; msn searches MSN; ms searches Microsoft's Web site; msdn searches MSDN; and technet searches TechNet. Listing 4 7: Search.inf

So that you can quickly open documents and programs you use frequently, Windows XP keeps history lists. These are MRU or most recently used lists. Table 4 7 shows you where in the registry the operating system stores these lists. Clear these lists by removing the keys associated with them. After removing the RecentDocs key, make sure you delete the contents of %USERPROFILE%\Recent, too. Table 4 7: History Lists Location Internet Explorer's address bar Run dialog box Documents menu Common dialog boxes Search Assistant Subkey HKCU\Software\Microsoft\Internet Explorer\TypedURLs HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32 \LastVisitedMRU HKCU\Software\Microsoft\Search Assistant\ACMru 5001. Internet 5603. Files and folders 5604. Pictures, music, and video 5647. Printers, computers, and people Search Assistant's history list deserves a bit more attention. The key ACMru contains a variety of subkeys, depending on the types of things for which you've searched. For example, if you search for files and folders, you'll see the subkey 5603, which contains a list of the different search strings. If you search the Internet using Search Assistant, you'll see the subkey 5001. You can remove each subkey individually to clear a specific type of query's history list, or you can remove the key ACMru to clear all of Search Assistant's history lists. The table contains a list of the subkeys that I've found in ACMru.
