How to use Explorer to show special objects

The Windows Shell program, Explorer.exe, is stored in the Windows folder, obtained through the environment variableWinDir. Usually, this folder is a part of the PATH environment variable. And as a consequence, we don't need to specify the whole path to Explorer.exe when calling this program.

The table below summarizes some of the command-line parameters passed to Explorer and the result of the execution. Note that all the examples given in this table have been tested only on the Windows XP platform. There is no reason that these examples will not work on at least NT-platforms (NT4/2K/XP/2003). The general Explorer command-line syntax is well known, and can be found on many Internet sites (see for example, the Q130510 article on the Microsoft site). But, the article's main contribution consists in showing how to specify some parameters (X, Y)=(object, sub-object) (see next section) to show special objects like My Computer, My Documents, Control Panel etc. Some of these objects are available in the Start Menu of the tasks bar (one of the graphical parts of the Explorer). To try the examples below, just open a console (cmd or command depending on your OS) and copy/paste each example. If you want to play with them, I have provided two complete and very small applications coded in Visual C++ 6 and Visual Basic 6. Some details of these applications are given below in the next sections.

Where the CLSIDs of special Explorer objects can be found?

There are many ways to find the CLSIDs referenced in the examples given in the previous section. Three methods are given below:

The first place to look for is the registry in the hive: HKEY_CLASSES_ROOT\CLSID, for example. Some of the special CLSIDS can also be found in the registry keys where the related namespace extensions are specified as in the key:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Explorer\ControlPanel\NameSpace\ where you can find all CLSIDs related to the Control Panel.

The second place to look for, is the OS shell resources DLL shell32.dll. To find the CLSIDs, you have to follow these steps:

• Step 1: Launch VS6, for example.
• Step 2: Click on the menu File-Open, and select file type: Executable Files, Open as: Resources, and then select the file shell32.dll, which is found in the System32 system folder (if the DLL is locked, you have to make a copy of it elsewhere and open it from the new place):

  

• Step 3: Open the custom resources "REGINST" as indicated in the figure below. Open this resource, and you will find all default CLSIDs installed on your OS. In fact, this file has the INF file format, and the CLSIDs can be found in the [Strings] section. All CLSIDs are prefixed by CLSID_.

  

  Note that you can also use public tools more appropriated to edit resources like: Resource Hacker by Angus Johnson.

The third place, is the Windows CD setup in the i386 folder in a INF file used during the installation process. If you have a Windows XP CD setup, you can find these CLSIDs in the HIVECLS.INF file.

Application 1

The application is a MFC Dialog application whose UI is illustrated at the top of this article. The design-time UI is illustrated below:

To test this application, you have to do three things:

1. Choose in the list, one of the objects.
2. Optionally, choose one of the two options or both of them.
3. Click on the button " GO TO -->!" in order to display the appropriate object.

The main procedure responsible for displaying the chosen object in the combo-box list corresponding to the click on the button labeled "GO TO -->!" is given below, and doesn't need any explanation for people comfortable with Microsoft C++:

Application 2

The second application is a VB 6 example using Internet Explorer Control whose UI is illustrated as the second figure at the top of this article. I want in this application to give another approach using Explorer objects different from the one used in VC++ sample application. The code is quite simple and makes use of one call to the Windows APIGetClientRect declared as:

 Collapse | Copy Code

Private Declare Function GetClientRect Lib "user32" (_
                    ByVal hwnd As Long, lpRect As rect) As Long

in order to resize the form. Note that in VB objects, dimensions are measured in Twips units, and since this API returns the window client rectangle in Pixels units, we have to convert these dimensions to Twips by using theScreen object properties : TwipsPerPixelX and TwipsPerPixelY (see the event Form_Resize() content). In order to display the Explorer objects, I have used the Internet Explorer method Naviagte2 with no optional parameters in the event handler cboObjects_Click(). The complete code is given below:
