Advanced Visual Basic 6.0 Programming Hands-On Training Class
This 5-day hands on Visual Basic 6 training course emphasizes object-oriented programming, component development and deployment, and techniques for connecting client applications to databases. Students start by interacting directly with the Win32 API to provide grounding in important Visual Basic programming principles. Students are then shown how to design and use class hierarchies. In the course's hands on exercises, students gain direct experience creating Visual Basic programs that both use existing components and create new ones. Students create both in-process and out-of-process COM components that can be deployed directly to the client's machine and shared by multiple client programs, as well as in-process components that can be deployed to remote servers.
Students build ActiveX controls that can be used both in Windows applications and on web pages. The course provides extensive practice developing database client/server systems. It provides thorough coverage of building 3-tier, component-oriented client applications that can use both RDO (ODBC) and ADO (OLEDB) to connect to databases. Students practice low-level programming to retrieve and output data from databases, invoke stored procedures, and also use Visual Basic database development tools such as DataView, DataEnvironment, and DataReport.
Students also use a suite of Microsoft's ActiveX controls to interact with a
local area network and/or the internet.
Course Prerequisites: Visual Basic programming experience.
