Take Assessment: Exercise 5

 

Time Zone Editor

Description

This assignment is to create an interface for entering a time zone.  This interface is patterned after the interface found in the standard Windows Date/Time Control Panel.  (To see this control panel, click on the "Start" button, then "Settings", then "Control Panel".  Double click on the "Date / Time" control panel.  Finally, click on the "Time Zone" tab at the top.)  You should create an interface with the components of the "Time Zone" tab, but not the tabbed dialog box or the other parts of the interface that allow the user to set the time and date.  As shown below, these components include a ComboBox for selecting a time zone by name, a map image, a CheckBox for indicating whether the system automatically updates its time to reflect daylight savings time (in time zones that have daylight savings time), and a set of  "OK", "Cancel", and "Apply" buttons.

 

Time Zone Editor

Description

This assignment is to create an interface for entering a time zone.  This interface is patterned after the interface found in the standard Windows Date/Time Control Panel.  (To see this control panel, click on the "Start" button, then "Settings", then "Control Panel".  Double click on the "Date / Time" control panel.  Finally, click on the "Time Zone" tab at the top.)  You should create an interface with the components of the "Time Zone" tab, but not the tabbed dialog box or the other parts of the interface that allow the user to set the time and date.  As shown below, these components include a ComboBox for selecting a time zone by name, a map image, a CheckBox for indicating whether the system automatically updates its time to reflect daylight savings time (in time zones that have daylight savings time), and a set of  "OK", "Cancel", and "Apply" buttons.

 

Based on user actions, you should keep track of:

• The index of the currently selected time zone
• The offset in minutes from GMT for the currently-selected time zone
• The title of the time zone

For this assignment, you should display the map, but you do not need to move the map to reflect the current time zone as is done in the original interface.  When the currently selected time zone does not use daylight savings time, the "Automatic adjustment" CheckBox should be disabled as shown above.  In other cases, this CheckBox should remain enabled.

When the user presses the "OK" or "Cancel" buttons, you should produce a small report of the current settings (similar to the one shown below), and then exit the interface (by "unloading" the form).  If the user presses the "Apply" button, you should produce a similar report but not exit the interface.  The report can be created using the MsgBox() subroutine provided by Visual Basic.  This routine will take a single string as a parameter and display that string along with an "OK" button.

Resources

The data tables and other resources provided below are intended to be cut from this page and pasted into your code or the Visual Basic property sheet editor.  Note that properties that have list values will accept pasting of multiple line text (e.g., cut from the text below) to fill the values for those lists.  To do this, click on the property value.  This will make a "down arrow" appear.  Press on this "down arrow," then click on the first line of the menu that appears (or highlight all the items in the menu if you wish to replace a set of existing entries). Finally, paste your text.  Take care not to introduce extra blank items and not to miss any items when cutting and pasting.
