The goal of this example is to document how you can use the free Lazarus IDE to create a DLL that contains a COM object and its type library. PicViewer is partly based on an example application from the Lazarus demo folder. The purpose of this project is to serve as a Code Repository, Wiki… Lazarus Code and Component Repository - Browse /Demos and examples at SourceForge.net

1.For this tutorial add a memo, a button and a TOpenDialog in the form. Methods. This project is intented to produce and create simple useful applications using the Lazarus IDE.

A method is just like a standard procedure or function, but can have some additional directives . Table of Contents, Lazarus Tutorials: Level Zero: If you are not only new to Lazarus, but also new to programming, or programming with Pascal, you might want to study Pascal a little first.
