Im having problems with the file search, file list and delete processes. Can someone please explain how to do them. The whole program assignment is listed below.
This program is to give you the opportunity to create a sequential file, add records to the file, change a record’s content, search for a specific record, list the contents of the file, and delete a record from the file. You will be called on to use all the skills and understanding of VB program concepts developed during this class.
1. The initial input data for this program is given below. You are to use this data to create a new file named “INVENTORY.TXT”. The data is to be placed in the file as follows: Stock Number, Stock Price, Quantity on Hand. Each item should be on a separate line. This is the file you will use for the remainder of the program.
2. The Form you design should be titled appropriately. It should have at least 6 buttons, 1 text box, and 1 list box. The buttons are to be titled appropriately.
3. APPEND (ADD) A RECORD PROCESS.
a. This should be an interactive process developed using INPUT BOXES.
b. The process should allow the addition of any number of new records to the file.
c. The process should use a LOOPING procedure.
d. Display a message in the text box when the append (add) process is complete and give a count of the number of records added
4. RECORD CHANGE/UPDATE PROCESS:
a. This is to allow the user to update the PRICE of an item in the Inventory file. This will require you to do the following:
b. Use INPUT BOXes to get the Stock Number and New Price of the item to be changed
c. Take the necessary action to change the price
d. Place a message in the text box that the item price was changed. For Example: “The price for XR546 has been changed to $4.75” or “The price for XR546 was changed from $5.75 to $4.75”
e. Ensure that the UPDATED “INVENTORY.TXT” is in the DEBUG folder and any temporary file used in this process is deleted from the DEBUG folder
6. FILE SEARCH PROCESS:
This process should search the INVENTORY file and display, in the text box, the STOCK NUMBER, STOCK PRICE, QUANTITY ON HAND and TOTAL VALUE of the most costly item (the item with the highest price).
7. FILE LIST PROCESS:
a. This process is to display the contents of the INVENTORY file in the list box. You should have appropriate report and column heading titles.
b. The report is to have column that shows the total value of each inventory item. The total value of an inventory item is its price times quantity on hand (Price * QOH)
c. The report is to have a total line showing the total value of all inventory items.
8. RECORD DELETE PROCESS:
a. Use INPUT BOXes to get the Stock Number of the record to delete
b. Take the necessary action to delete the record
c. Place a message in the text box that the record has been deleted
d. Ensure that the UPDATED “INVENTORY.TXT” is in the DEBUG folder and any temporary file used in this process is deleted from the DEBUG folder
9. PROGAM EXIT PROCESS: End the program using an Output Message box.
