Question

***PLEASE AVOID USING A "CLASS" IN SOLUTION*** thank you.

Please use Visual Studio to write a C# program to allow user to store contact information.

1. User should be able to type in name, E-mail and phone number in the text boxes and click Add button to save the contact record. Every time when user add record, user should be able to see all the information displayed in the right side display text box. (allow up to 10 records)

Main Form 4 / 10 Name === Add Name === Name : Tom Wood Email: [email protected] Phone : 734-909-2356 E-mail Phone Add Find Name Name : Su Mall Email : [email protected] Phone : 345-343-5674 ==================== Name : Joe Timer Email: [email protected] Phone: 745-909-4544 ==================== Name: John Smith Email : [email protected] Phone : 345-343-7788 SESSEEEEEEEEEEEEEEE Update Sort by Name Close

2. User can type name in the Name Textbox and click Find Name button to look for the that person. If the name is in the record, display the record in the Name, E-mail and Phone text box. If not, use Message.Show() to send out a not found message.

3. If the record is found by the Find Name button, user can change any field (Name, E-mail and Phone) in the Textboxes and click Update button to update the information. All the records should be displayed in the display box again.

4. User can click the Sort by Name Button to sort all the record in the ascending order by name and display in the display box. DO NOT print out any empty element/spot in the array. (Only sort the copies of the Arrays)

5. Data validation and Record counter: 5 and 5 points

If user try to add empty data in the record (Name, E-mail, or Phone), the program must be able to check and show the proper error message by using Message.Show() (Example: Name is a required field!!)

Please have a record counter displayed on the top (Error Message over 10 records).

Important Note:

The output TextBox properties:

Multiline: true

ScrollBars: Vertical

TextBox output string line breaker: \r\n
