The computer architecture shown in FIG. 1 includes a central processing unit 102 (“CPU”), a system memory 104, including a random access memory 106 (“RAM”) and a read-only memory (“ROM”) 108, and a system bus 110 that couples the memory to the CPU 102. A basic input/output system containing the basic routines that help to transfer information between elements within the computer, such as during startup, is stored in the ROM 108. The computing device 100 further includes a mass storage device 120 for storing an operating system 122, application programs, and other program modules, described in greater detail below.
The mass storage device 120 is connected to the CPU 102 through a mass storage controller 118 connected to the bus 110. The mass storage device 120 and its associated computer-readable media provide non-volatile storage for the computing device 100. Although the description of computer-readable media contained herein refers to a mass storage device, such as a hard disk or CD-ROM drive, it should be appreciated by those skilled in the art that computer-readable media can be any available media that can be accessed by the computing device 100.
By way of example, and not limitation, computer-readable media may comprise computer storage media and communication media. Computer storage media includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EPROM, EEPROM, flash memory or other solid state memory technology, CD-ROM, digital versatile disks (“DVD”), HD-DVD, BLU-RAY, or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computing device 100.
According to various embodiments of the subject matter described herein, the computing device 100 may operate in a networked environment using logical connections to remote computers through a network 114, such as the Internet. The computing device 100 may connect to the network 114 through a network interface unit 112 connected to the bus 110.

As mentioned briefly above, a number of program modules and data files may be stored in the mass storage device 120 and RAM 106 of the computing device 100, including an operating system 122 suitable for controlling the operation of a networked personal computer, such as the WINDOWS XP operating system from MICROSOFT CORPORATION of Redmond, Wash. Other operating systems may also be utilized, such as the LINUX operating system, the OSX operating system from APPLE COMPUTER, INC, and others. The mass storage device 120 and RAM 106 may also store one or more program modules. In particular, the mass storage device 120 and the RAM 106 may store an application program 126 and a multi-valued property user interface (“UI”) control 124. As will be described in greater detail below, the multi-valued property UI control 124 may be utilized by the operating system 122 and the application program 126 to allow a user to specify and edit the values of multi-valued properties. As described herein, the term multi-valued property refers to a property that may have more than one value. The UI control 124 may be instantiated and utilized as needed by the operating system 122 and the application program 126.
The UI control 124 may be utilized by virtually any type of operating system or application program. For instance, the UI control 124 may be utilized by the operating system 122 to specify values of properties for files accessible via a file system shell browser provided by the operating system 122. The UI control 124 may also be utilized by an application program 126 to specify recipients of electronic mail messages, properties for word processing or other types of documents, and virtually any other type of multi-valued property. It should be appreciated that these examples are merely illustrative and that the UI control 124 described herein may be utilized to specify values for any multi-valued property. Additional details regarding the operation of the UI control 124 are provided below with reference to FIGS. 2-6.
Referring now to FIGS. 2-3B, additional details regarding the operation and use of the UI control 124 according to one embodiment will be provided. FIG. 2 shows an illustrative screen display 200A provided by the UI control 124 when instantiated. As shown in FIG. 2, the screen display 200A includes a field 204 where user input may be received for entering the values of a multi-valued property. A field descriptor 202 may be displayed adjacent to the field 204 for providing a text description of the multi-valued property being edited. For instance, the example shown in the screen display 200A is configured for specifying the authors of a document. The authors property in this example is a multi-valued property because multiple authors may be specified. As also shown in FIG. 2, a prompt string 206 may also be displayed in the field 204. The prompt string 206 provides a textual indication as to where the display should be selected to add a new value to the field 204. The prompt string 206 may be displayed with a visual indicator to provide a hint that it may be selected. For instance, in FIG. 2 the prompt string 206 is displayed inside a dashed box. Other types of visual indicators may also be utilized, such as bold or colored text, highlighting, flashing text, or others.
FIG. 3A shows a screen display 200B illustrating the display provided by the UI control 124 following the selection of the prompt string 206. In this embodiment, selection of the prompt string 206, such as through selection by a mouse click or equivalent keyboard command, causes the prompt string 206 to be removed and an insertion point 208 to be placed within the field 204. The insertion point 208 signifies the location that typed characters will appear within the display 200B. In this embodiment, selection of the prompt string 206 also causes a menu 210 to be displayed adjacent to the field 204. Selection of the UI button 205 may also cause the menu 210 to be displayed in one implementation.
As shown in FIG. 3A, the menu 210 includes one or more suggested values 212A-212D for the field 204. In this example, the suggested values 212A-212D have been displayed in the menu 210 in response to the selection of the prompt string 206 or the UI button 205. Each of the suggested values 212A-212D may be individually selected for inclusion in the field 204. In particular, in one implementation, the check boxes 214A-214D are displayed adjacent to each of the respective values 212A-212D. Selection of a check box causes the corresponding value to be added to the field 204. For instance, in FIG. 3A a check 216 has been placed in the check box 214D corresponding to the value 212D. This causes the value 212D to be placed in the field 204. This is illustrated in the screen display 200C shown in FIG. 3B. It should be appreciated that any number of the values 212A-212D may be displayed in the menu 210 and that any number of the values may be selected in the manner described above for inclusion in the field 204. It should also be appreciated that the values selected and included in the field 204 become values of the multi-valued property associated with the UI control.
Referring now to FIG. 4A, a screen display 200D showing an alternative embodiment of the user interface control provided herein will be described. In this implementation, the screen display 200D includes the field 204, the field descriptor 202, and the prompt string 206. However, in this implementation, the menu 210 is displayed in response to receiving one or more typed alphanumeric characters in the field 204. For instance, in the screen display 200D shown in FIG. 4A, the character “M” has been typed in the field 204. In response to the receiving the typed character, the menu 210 has been displayed with a number of possible values 212E-212H for the field 204. In this implementation, the possible values 212E-212H are selected based on the alphanumeric characters typed in the field 204. So, for example, because the letter “M” was typed in the field 204, the possible values 212E-212H were selected that also included the letter “M.” It should be appreciated that the possible values 212E-212H may be continually modified based upon additional characters typed in the field 204. In this manner, the values 212E-212H become more specific as the number of characters typed in the field 204 increases.
As also shown in FIG. 4A, each of the values 212E-212H is individually selectable for inclusion in the field 204. In this regard, the check boxes 214E-214H may be displayed adjacent to each of the possible values 212E-212H. Selection of a check box will cause the corresponding value to be included in the field 204. For instance, in FIG. 4A, the check box 214H causes a check 216 to be displayed and the corresponding value 212H to be placed in the field 204. FIG. 4B shows an illustrative screen display 200E where the values 212F and 212H have been selected for inclusion in the field 204. In this example, a box 220 has been placed around the value 212G to signify an active value 212G when a keyboard is utilized to navigate the menu. It should be appreciated that de-selection of a previously checked check box causes the corresponding value to be removed from the field 204.
Referring now to FIG. 5A, a screen display 200F will be described showing an alternative screen display provided by the UI control 124. In this example, the values 212J-212M are displayed in the menu 210 in a hierarchical format. This may be useful, for example, for specifying hierarchies of possible values for the multi-valued property. For instance, in the example shown in FIG. 5A, the characters 218 spelling “LEGAL” have been typed in the field 204. In response, a number of possible values 212J-212M have been displayed in the menu 210. These values are displayed in a manner that conveys their hierarchical relationships to one another. In particular, the a value 212J is displayed which, when selected using the parent check box 214J will cause each of the child values 212K-212M to also be selected. In response, check marks are placed in each of the check boxes 214J-214M. Alternatively, each of the child values 212K-212M can also be selected individually.
Referring now to FIG. 5B, a screen display 200J will be described showing an alternative screen display provided by the UI control 124. In this example, the values 212J-212M are displayed using a menu 210A and a sub-menu 210B. This arrangement is also useful for specifying hierarchies of possible values for the multi-valued property. For instance, in the example shown in FIG. 5B, the characters 218 spelling “LEGAL” have been typed in the field 204. In response, a number of possible values have been displayed in the menu 210A. When one of the values is selected, such as the value 212J, a sub-menu 210B is displayed that shows the child values 212K-212M for the selected value 212J. The sub-menu 210B is displayed in a manner that conveys the hierarchical relationship of the child values 212K-212M to the parent value 212J. Selection of the value 212J using the parent check box 214J will cause each of the child values 212K-212M to also be selected. In response, check marks are placed in each of the check boxes 214K-214M. Alternatively, each of the child values 212K-212M in the sub-menu 210B can also be selected individually using the check boxes 214K-214M.
FIG. 5C shows a screen display 200G following the selection of the value 212J in FIG. 5A. In this implementation, the value 212J has been tokenized and included in the field 204. FIG. 5D shows a screen display 200H illustrating an alternative implementation, wherein each of the values 212K-212M are shown individually in the field 204 in response to the selection of the value 212J. In this embodiment, an icon 222A-222C is also displayed in the field 204 adjacent to the respective value 212K-212M. It should be appreciated that icons or other visual indicators may be displayed adjacent to specified values in the field 204 in any of the embodiments described herein.
Turning now to FIG. 6, an illustrative routine 600 will be described showing the operation of the computer system 100 for providing a user interface for specifying the values of multi-valued properties. It should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance requirements of the computing system. Accordingly, the logical operations described herein with respect to are referred to variously as operations, structural devices, acts, or modules. These operations, structural devices, acts and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination.
The routine 600 begins at processing operation 602, where the screen display provided by the UI control 124 described herein is displayed. The routine 600 then continues to operation 604 in response to the selection of the control. This may occur, for instance, through the use of a mouse input device or keyboard command selecting the screen display provided by the control. At operation 604, a determination is made as to whether values should be automatically suggested in response to the selection of the control in the manner described above with respect to FIGS. 2-3B. If values are to be automatically suggested, the routine 600 branches to operation 608, where the menu 210 is displayed with the suggested values. If values are not to be automatically suggested, the routine 600 branches from operation 604 to operation 606. It should be appreciated that the UI control 124 may be programmed to either suggest values or not suggest values.
At operation 606, a determination is made as to whether characters have been typed in the field 204. If so, the routine 600 branches to operation 610. The routine 600 also branches to operation 610 if characters are typed in the field while at operation 608. At operation 610, the menu 210 is displayed with possible values based on the typed characters. At operations 608 and 610, a user may select values in the menu for inclusion in the field 204. When the user has completed selecting values, the routine 600 branches from operations 608 and 610 to operation 612 where the menu 210 is removed from the screen display. The routine 600 then continues from operation 612 to operation 614 where the selected values are added to the field 204, thereby specifying the selected values as properties of the corresponding multi-valued property. The routine 600 then returns to operation 602 from operation 614, where it begins again.
