TIPS :: By default, forms include maximize and minimize buttons, a resizable border, and a menu that provides additional commands to resize the form.

The bsNone value for the BorderStyle property is used when you want to remove the Border and the caption bar from the form - leaving only the content visible. This setting is commonly used when creating a splash screen. One downside to setting the bsNone value for BorderStyle is that such forms cannot be resized!

There may be situations when you want to remove a form's border (and title bar) *but* still leave the option for a user to resize the form. Here's how...

in Delphi :: When you want to learn a new programming language you pick a book or find an online tutorial. The first project you will create would be a "hello world" type of application - such a program should be one of the simplest programs possible in a computer programming language.

After a few "hello world" programs, you would start building your fist non-trivial application.

VCL Ideas :: If you are developing a "quiz-like" type of application, or an "exam-like" application, a user needs to make a selection and click the "Next" button, to go to the next "question".
In such scenarios you might need to force a user to make a selection (choose the "answer") within a specified time interval.

You, as a developer, should include some code that will programmatically fire the OnClick event of the "Next" button, when the time has elapsed. Here's how ...

in TListView Ideas :: The TListView Delphi control displays and manages a list of items, displayed in columns, vertically or horizontally, with small or large icons.

Windows XP, and later versions, support grouping items in a list view. With the grouping feature of the ListView control, related sets of items can be displayed in groups. Groups are separated on the screen by horizontal group headers that contain the group titles.

If you are using Delphi 2007, Delphi 7 or any other previous version, you can also have grouping functionality in the TListView control.

TIPS :: By default (Windows drawing), all items (tree nodes) of a tree view share the same font styling. If you only want to apply *bold* to some tree items (their Captions), you can use a "special" TreeView API. Here's how to *bold* tree items in Delphi applications.
