4.2.2 Block 1: Show Date and Time loop
This loop displays the current date and time in two text fields on the GUI.
4.2.3 Block 2: Operation loop
This loop is the actual programming loop. It will run indefinitely unless you stop the program.
If a button is pressed or if status information is to be loaded from the database or if the user
selects another PPM the corresponding block will be executed.
4.2.3.1 Block 2a: start of programming
This block is executed when the button Start is pressed. It will insert a record into the
progstatus table. All the required information is taken from the text fields and list boxes of the
GUI.
After inserting the new entry into the database, you’ll need its ID to reference it for all later
reads and writes. This can be done by asking for the latest ID in the table progstatus. The
SQL command
SELECT MAX(ID) from progstatus
gives us a two dimensional array containing only the maxid.
Straight after starting the program process a new entry in the EQWriteData table will be
created to take all the additional data which has to be written to the target. In this example
the SQL command
INSERT into
VALUES(...)
EQWriteData
(
ID,
Serial,
Product_id,
Revision,
No_of_updates)
with appropriate values creates this entry.
