One of the problems that a beginner encounter when there is a project uploaded here, is they do not know on how to change the connection string that points to the correct database location. This is true with MS Access and even with SQL Server. Some programmers don’t add a code that will automatically change the location of the database just in case it will be ported in other machine.
This tutorial will show you how to connect vb6 with ms access using module and also how to use reports in a very simple example.
Thank You.

Now that you have added all the necessary forms to your project and a menu system, let us now add a login form. This will ensure that only the person that has the account information can login to your system.

In our previous tutorial I discuss on “How to Create Master/Detail Windows Forms” on our Library System Project.
Today we will add MDI Form and create a main menu to open the forms on our project. If you follow closely this tutorial you will have now several Windows Forms on your project.
Please follow the steps below to Add MDI Form and Main Menu on your Library System project.
If you are using SelectedIndexChanged in your ComboBox may be you encounter a problem with events being fired even if you did not click the ComboBox.
This happens when you open and close your Windows Form. The workaround for this is to use RemoveHandler statement.
Here’s an example:
