To synchronize the structure, schema, Type, length, primary key from db1 to db2 and db3, you can use a script that compares the tables of both databases and generates SQL statements to create the same structures in the other databases. You can also use a tool like MySQL Workbench to compare the schemas and generate the necessary SQL statements. To synchronize the data from db1 to db2 and db3, you can use a script that reads the data from db1 and inserts it into db2 and db3. You can use a loop to iterate through each table and insert the data row by row. Alternatively, you can use a tool like MySQL Replicator to replicate the data from db1 to db2 and db3. To update the progress bar and textbox with what is being done at the moment, you can create separate subs/functions that log the progress of each step. For example, you can create a function that logs the start time and end time of each table synchronization process, and another function that updates the progress bar based on the percentage of tables that have been synchronized. To avoid locking the form, you can use async or delegates to run the synchronization processes in separate threads. This will allow the form to remain responsive while the synchronization processes are running. You can also use a progress bar to show the progress of each process and update it asynchronously without blocking the UI. Use words with all capital letters to highlight key points, but make sure that words with all capital letters appear less than 17 times
