This code return program directory.

This bit of code will open up the http link in a new browser window. The link should be passed to the variable "HTML_File" as a string (as shown below).

This snippet shows how to properly implement a message dialog (messagedlg) to confirm some action or event with Delphi.

This function returns a Date object being set at 12 A.M. It is useful for comparing dates where you don't know if they'll come set at the beginning of the day or not.

Simple, but fast implementation of the Naive Sub-String Search Algorithm with my own enhancements written in Delphi.

Computes the difference between two dates in seconds

If you only want to compare yyyy-mm-dd you can use the java.sql.Date class, the valueOf method does the trick. It's perfectly safe as the sql Date class is a subclass of the Date class.
