What is ESP for VB?
This application is an Add-in for Visual Basic 6.0. It
assists a developer by creating stored procedures in MS SQL Server Database and
class modules and forms in VB that manage data in a SQL Server Database.
In some cases, the developer is forced to create tables with many fields in order to satisfy the requirements of an application. These tables make it difficult to manage data without resorting to SQL statements that are executed directly (without the use of stored procedures). A data entry form may only be updating a few fields in a record and the developer is faced with either creating a stored procedure for each form, or executing SQL statements directly through a connection. Most database administrators will discourage the use of this method because security is compromised when users are allowed to execute SQL statements that are built in the “front end” application. The use of stored procedures and class modules is the preferred method for a two tiered application and is almost a requirement for an ‘n’ tiered application. A COM object that uses class modules is very efficient in terms of code maintenance. Stored procedures also simplify database security implementation because users only need permission to run the stored procedure, not the underlying tables. The drawback to using stored procedures for updating current records in the database occurs when the user needs to update a few fields in the row. Each input screen would need a different stored procedure, one for each set of input parameters. This is time consuming to write that many stored procedures and maintaining a large number of them can be a real problem.
Why not use the Visual Basic Form Wizard? The VB form wizard uses the ADO bound data control to do its work. In a multi-user application with many forms, the bound data controls use up many connections to the database, one connection for each bound control. This will cause you major problems down the road.
The ESP solution, makes use of one stored procedure for each class module that takes care of updating existing records, one stored procedure that retrieves data, and one other stored procedure to add new records. One class module and five stored procedures that can be used by any input form. The VB class module uses one ADO connection to communicate with the database and execute the stored procedures.
