Detailed ways

The invention provides a mobile storage device whose icon can be changed independently, and the user can define the icon of the mobile storage device on the host system platform by himself. By setting personalized icons, such as cartoon characters, animals and other graphics, the mobile storage device such as flash disk is easier to identify, more convenient to use, and more personalized on the operating platform of the host system.

The marking method of the icon of the mobile storage device provided by the present invention is mainly realized by installing an application program at the host end, such as the Windows OS series of Microsoft Corporation. Through this resident Windows system application, the application has a window that can receive Windows system information.

On the Windows operating system of Microsoft Corporation, when the operating system detects that a new mobile storage device or other storage medium is inserted, the operating system will send a mobile device access message to the window of each application program. The implemented application program resident in the Windows system can also detect the message. After receiving the message, the application program can obtain the device handle of the corresponding access device, and can physically read and write the device. By reading the Define the device data of the address to obtain the private information of the device. Through the read private information, it is judged whether the device is a mobile storage device corresponding to the software. If it is a mobile storage device corresponding to the software, the storage path of the relevant setting icon is called, and the corresponding icon is displayed on the system tray. Icons can be defined by the user for easy identification.

The method of user-defined mobile storage device icons is realized by modifying the Windows registry. On the Windows operating system, the contents under the key KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons are some drives corresponding to the drive letter Feature value, for example, if the C drive has some features, you can find the corresponding key value of C under the key value, and there are some key values with defined features under the corresponding key value of C, such as DefaultLabel. The default volume label value of the disk, and DefaultIcon defines the default icon of the disk, and the content of this key value is the storage path of the icon file. The application program implemented by the present invention can create or modify the corresponding key value in the registry to be a user-defined icon when receiving the message of the insertion of the mobile storage device and determining that it is the corresponding mobile storage device, so as to realize the change of the driver icon , and call the system API SHChangeNotify after the change to refresh the system immediately to make the change take effect. When the application program receives the removal of the removable storage device, it deletes the corresponding key value in the registry to prevent the user from using the software-defined Situation of the icon.

The marking process of the icon of the mobile storage device can be realized through the automatic operation technology. For the technical solution of the automatic operation, please refer to the patent application No. 03146090.9.

By creating the Autorun.inf file in the root directory of the mobile storage device, and filling it with [AUTORUN]Icon=<Icon file path>, where <Icon file path> is the path of the icon file of the mobile storage device, in the mobile storage When the device is plugged into the host system, a self-executing program installed in the storage device starts.

During the running of the automatic execution program, a dialog box will pop up to prompt the user to select the displayed icon and set a time limit, such as 3 seconds. If the user does not choose within the limited time limit, the previously saved icon will be used Set or use the default icon (in case of first use). Of course, the icon can also be changed by clicking the small icon on the system tray to open a dialog box, modify and save it, instead of only popping up a dialog box after the removable storage device is inserted into the host computer for selection by the user.

Please refer to the icon change flow chart of the mobile storage device shown in Figure 1. First, the mobile storage device is powered on 10, that is, the mobile storage device is inserted into the host system; secondly, the automatic execution program stored in the mobile storage device runs 20; then , the automatic execution program is used to display a default or user-defined small icon on the system tray through the Shell_NotifyIcon() function call; then, modify the registry key value 40, that is, change the content of the DefaultIcon key value to the icon specified by the user The path of the file, the icon under this path can be the default icon or the icon selected by the user; finally, the automatic execution program calls the function SHChangeNotify () to refresh the operating system window, and the new icon appears.

Please refer to Fig. 1 again, according to the implementation of autorun, the auto-execution program can also be run by copying another running program to a certain position in the host system, step 22 shown in Fig. 1, referred to as the second running program , and then run by the second running program to modify the DefaultIcon key value in the registry. The detailed running process of the second running program is described as follows.

After the second running program starts, first determine the storage device 24, that is, which storage device has started itself (how to start this running program), the process of searching is to realize by reading the IIR table of the storage device, which disk to start after obtaining After you have identified yourself, you will also get the drive letter and handle of the disk at the same time. At this time, the program first calls the path of the icon file in the mobile storage device through the Shell_NotifyIcon() function, and displays a small icon on the system tray. The icon can be the default The icon or the icon selected by the user, and the icon file is still stored in the mobile storage device, the user can click this icon to pop up a window to change the icon; then the program changes the icon of the mobile storage device by modifying the registry ;Finally, the program calls the SHChangeNotify() function to refresh the Windows window to make the new icon appear.

After completing these operations, the second running program is always in a sleep state until the message that the flash drive is removed is received. After receiving the removal message, the second running program modifies the contents of the registry, removes the icon setting corresponding to the drive letter, and then removes the small icon in the system tray through Shell_NotifyIcon(), and finally the program closes itself and completes the whole process. process.

The above description is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications made to the present invention, these improvements and modifications are also It should be regarded as the protection scope of the present invention.
