Using Data topic (classic post):
Set File Extension to Always Show in Explorer
by Scott Wehrly
The default setting in Windows Explorer is to always hide known file extensions. This Delphi code shows you how to programatically set your own extension to always show in Explorer.

Coding Tasks topic (classic post):
Delphi Best Practices 2: Reusable Main Forms
by Wes Peterson

How often have you started a new Delphi project, then spent some time fleshing out the default main form provided by Delphi?

This task only needs to be done once or twice. Delphi then allows us to re-use this work at the start of each new project.

Source code is included.

Question: How do you check screen resolution in Delphi?

Answer:

Use the Screen variable which is a TScreen. The Screen variable is a TScreen component that represents the screen of the system on which the application runs. By default, applications create a screen component based on information from Windows about the current screen device and assign it to Screen.

For example, put the following code in a button click:

MessageDlg( 'screen width = ' + IntToStr( Screen.Width ) + ',
screen height = ' + IntToStr( Screen.Height ),
    mtInformation, [mbOk], 0 );
