The video tutorial provides step-by-step instructions on how to navigate through records using VB6 programming language. The presenter explains the compatibility of VB6 with newer operating systems and demonstrates how to connect a Microsoft Access database to VB6. The video also shows how to create navigation buttons to view records, and explains how to use SQL statements to retrieve data from a database. The tutorial encourages viewers to use these functionalities as a learning aid to supplement programming education.
00:00:00 In this section, the YouTuber greets his viewers and gives his contact details for custom program requests. He also addresses a common question regarding the compatibility of Visual Basic with newer operating systems and informs that it can run on Windows XP, Vista, 7, 8, and possibly on Windows 10. He provides an example of running Visual Basic on a Windows 8.1 with a low-end processor and RAM. He also talks about how video playlists on the channel are arranged based on topics, and viewers can watch them accordingly.
00:05:00 In this section, the video discusses how to create navigation buttons in Visual Basic for viewing records in a database. The compatibility feature on Windows operating systems is also mentioned, which allows older programs to be installed and run on newer operating systems. The video then proceeds to show how to connect a Microsoft Access database to Visual Basic and create navigation buttons for viewing records. The process involves creating a form and coding buttons for navigating through the records. The video recommends watching previous videos on database connections in order to fully understand the process.
00:10:00 In this section, the user is shown how to create a module and a class module to connect VB6 to a database and retrieve data from it. A form is created with two labels and four command buttons to display and navigate through the data. Label one is for the question and label two is where the data from the database is shown. The four command buttons provide options to show the first, previous, next, and last data on the database. The user is also shown how to format the buttons and labels to make them look better on the form.
00:15:00 In this section of the video tutorial, the presenter shows how to connect VB6 to a database using Microsoft ADO data control 6.0. The presenter also explains the use of class modules and sets the font property for labels. They then demonstrate how to load the first question of a quiz from the database into a label on the form and show how to use the next button to navigate to the next question until the end of the questions in the database is reached. The presenter uses SQL statements to retrieve data from the database and assigns variables to handle record sets.
00:20:00 In this section, the video explains how to retrieve data from a table in a database using SQL statements. Once the SQL statement is used, the files inside the table can be retrieved and accessed. The video also demonstrates how to access data inside specific fields and load it into visual basic components such as labels. The video concludes with a demonstration of how to run the program, retrieve questions from the database, and use buttons to navigate between them.
00:25:00 In this section, the video tutorial explains how to encode the commands to show the next question on the database using VB6 programming language. The video shows how to use the "move next" command and how to add an "if statement" to make sure that the program can read the next data on the database. The tutorial also shows how to handle the situation when there is no next data on the database, by adding a message box to inform users that they are at the end of the questions and cannot go further.
00:30:00 In this section, the instructor demonstrates how to add commands and codes to the "Previous" button in the VB6 programming language to avoid errors. The instructor uses an "if statement" to ensure that the application doesn't attempt to access data outside of the database. Additionally, the instructor shows how to use "BOF" to indicate the beginning of the file in the "Previous" button's code. Finally, the code is tested to show that the application can retrieve and move data between records successfully.
00:35:00 In this section, the video explains how to navigate records in a database using VB6. The video demonstrates using buttons to go to the first, last, next, and previous records. The video also explains how to use these functionalities to retrieve data from a database and encourages using these tools as a learning aid to supplement programming education.
