As usual, the quick and dirty way

If your work requires that you spend a long time on Internet Explorer (IE), you may have felt the need for quick access to some of your favourite programs like Notepad, IrfanView, etc.

In this article, you will learn about a simple way to customize your IE toolbar. This involves adding a few keys to the Windows registry. Windows registry is the main storehouse of vital information about your Windows installation. Be careful or you may have to install Windows again.

Anyway, here we go. In the first example, I will tell you about how I added a toolbar button for the Notepad application. Select the Start menu button and click on the Run option. Type regedit and click the OK button. The Registry Editor will be displayed. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Extensions key. Here, you might see keys with names like {A5D12C4E-7B4F-11D3-F5C9-0050045C3C96}. The names of these keys are called globally unique identifiers or GUIDs. In my machine, the A5D12C4E-7B4F-11D3-F5C9-0050045C3C96 GUID uniquely represents the toolbar button for Yahoo! Messenger. For every button you try to add to the IE toolbar, you must come up with a new unique GUID.

For Notepad, I created a key at Extensions branch with a brand-new GUID. (Select Extensions, right click, and select New » Key.) The professional way of generating a unique GUID is to use a tool like guidgen.exe or uuidgen.exe. The MSDN says, "Guidgen.exe never produces the same number twice, no matter how many times it is run or how many different machines it runs on." Because I decided did not have this tool, I decided to take a risk by generating a new GUID myself. I made some random changes to the alphabets and the numbers in GUID used by Yahoo Messenger.

The GUID is in hexadecimal format, which means that it is made up of numbers from 0 to 9 and the alphabets A to F. In other words, the ID cannot have alphabets from G to Z or fancy characters like *,#,/,%,^,&,* and @.

In the right-side pane of the registry editor, I created the following string values: ButtonText, clsid, Default Visible, Exec, HotIcon, Icon, MenuStartBar, and MenuText. (Right click, select New » String Value.) I set ButtonText and MenuText to Notepad. This value was to be displayed as the label below the toolbar button. The value used by MenuStatusBar was to be displayed in the IE status bar when the mouse pointer or the cursor hovers over the corresponding Tools menu option. The clsid value was set to {1FBA04EE-3024-11d2-8F1F-0000F87ABD16}. This value is a set standard and you should include this as is for any toolbar buttons you may create for your browser. The Exec value was set to the path to the Notepad application file (c:\winnt\notepad.exe). The Default Visible value was set to Yes.

In the Icon and HotIcon values, the number after the comma identifies icon group inside the Notepad application file (notepad.exe). An icon from this icon group was to be displayed on the IE toolbar button. To identify the number for the icon group used by notepad.exe, I used a program called Resource Hacker. If you don't have Resource Hacker, you can create an icon (ICO) file for the toolbar button application and then then set its path as the Icon and HotIcon values. To create an icon file for your toolbar button application, open its exe file in IrfanView. A number of icons inside the application file will be displayed. You can select an icon from that and save it as a 16x16 24bpp icon file.

UPDATE (14/11/05): Apart from adding ordinary applications to the IE toolbar, you can also add useful script-based applets that will work inside the IE window. For this, you need to create a Script string value instead of an Exec value. The Script will point to a HTML file containing Javascript. In this example, I have created buttons that will scroll up and down a page. If you don't have relevant icon files, make a bitmap file in Paint and then convert it to an ICO (icon) file using IrfanView.

Because of problems with Blogger.com not accepting script tags, a $ symbol has been included in the code listings. If you plan to use them for your machine, please remove these characters.
