Assignment: Array Based GUI Assignment
Telephone call data has been collected from a company's telephone switch. You have been asked to analyze it and produce various statistics.
Input File
The input file is a sequential file. It is in no specific order. The file contains an extension number, type of call, and the length of call in seconds. A record is produced each time a call is made from that extension. You should create your own test file.
FieldTypeDescription
ExtensionIntegerExtension number. This is a 4 digit number. Valid Extensions are 2000 to 2020.
TypeIntegerValue of 1 means internal, any other value is an external call.
TimeLongLength of call in seconds
Example:
2000,1,60 : -->>>> Extension 2000 had an internal call that lasted 60 seconds
2000,1,356: -->>>> Extension 2000 had an internal call that lasted 356 seconds
2019,2,65: >>>> Extension 2019 had an external call that lasted 65 seconds
2001,1,355: -->>>> Extension 2001 had an internal call that lasted 355 seconds
Process
1.Use 2 arrays to accumulate the time of calls for each extension, both internal and external.
2.The reports and queries are to be produced from the arrays.
Hints:
Create 2 arrays: one for internal calls and one for external calls.
Load the arrays in Form Load: do not do any calculations here.
The report and queries can totally be produced from the arrays.
Output: Report
Telephone Useage Report
Extension Internal External
200045003500
20011935022981
20022333900
20033144122
Totals9999999999
Output: Queries
On the form add add query capability.
1.Average Total Utilization: Internal Calls: 9999 (total length of all internal calls / number extensions)
2.Average Total Utilization: External Calls: 9999
3.Extension with the highest internal call utilization: Ext xxxx; 9999 seconds.
4.Extension with the highest total utilization.
Form Design
The design of the form is up to you. However, use the following guidelines:
use menus (preferred) or command buttons
use a common dialog box to ask for the file name
use a list box or text box to display the output
the caption on the form should include your name
