3. Project Description
My project combines an end of day calculator for closing out the till at the end of day.
It also focuses on using a database for managing special ordered parts for our clients.
It will be used primarily by our store only at first, with hopes to integrate it into the other 40+ stores.

4. Key project tools Visual Studio 2019 Enterprise Edition
For IDE, using C#
MS SQL Express 17
For Database
MSSQL Sever Management Studio 18 (SSMS)
For Database management

5. Features & functions Load Function
Upon loading, allows the datagridview alternating colors for an easier time navigating the sea of data.
cPP_Order_SheetTableAdapter1.Fill grabs the data from the DB and fills the DGV.
FirstDisplayedScrollingRowIndex, was first used when hitting the “add” icon which works great. I would love to be able to start the DGV at the bottom for a new entry, as those are the parts that still need to be ordered.
Features & functions

6. Key input/output captures
Top Image
While you wont be able to tell from the PP, you’ll see hitting the plus icon brings you to the bottom for easily adding a new entry.
Bottom Image
Display the bottom entry.
What is not pictured, is the header remains “frozen” so a new employee will always know what type of data needs to be entered and where.

7. Database ERD Diagram The new and improved ERD diagram!
Accounts and Vendors share a one to many relationship with each type of special order that can be placed.
I thought about splitting Vendors, but decided against it, but I could more than likely create a more refined Vendors list.
Added Access_Levels and Users tables, for an end goal of restricting certain to certain tasks.
Example:
Admin level has access to everything (Add users + below)
Purchasers have access to add Vendors + below
Users have access to add Customers.

8. Primary technical difficulties
Trying to get the DataGridView to automatically go the last entry has been some what of a pain.
Thankfully, I just started trying to incorporate this 07/07/2019, so I still have some time to fix my problem.
When trying to update the DB in my project, I managed to delete it causing quite a few issues.
Thankfully I was able to restore most of everything with in an hour or so’s time.
This lead me to start using Version Control to create branches before doing major changes. :-D

9. Key code snippets ToolStripButton_Update ToolStripButton_Save
This was original used as a “save”
Changed code to allow a user to “refresh” the table without having to close the application
ToolStripButton_Save
This function validates the data (you will get an error while entering data anyway)
Ends editing of the current line
Updates the DB/Display with the newly entered data.

10. A Difficult problem and a solution!
No real major issues besides previously listed.
Things have been pretty smooth sailing when I have been focused on getting the DataGridViews set up the way I want for each table. Just takes time to fine tune everything due to OCD.
