Introduction - by Paul Griffiths For many years I have benefited from the spirit of cooperation and sharing that exists within the programming community. In particular the Delphi community has actively shared code and information. In an attempt to partially repay those who have given their time and expertise to provide Delphi source code to other programmers on the Internet, I have prepared a few simple tutorials. Each tutorial includes source code that can be copied into your own Delphi program. I hope you find them helpful. |
| These tutorials provide step-by-step instructions to help you accomplish specific programming tasks using Delphi and the Object Pascal Language. |
| Two simple solutions to pause program execution in Delphi without adversely affecting system performance.
|
|||
| Obtain the correct file size from FindFirst and FindNext, even when the file is larger than 2GB.
|
|||
| The date and time that a file was created, accessed and modified are expressed in Coordinated Universal Time (UTC) format. This tutorial shows you how to convert the data to a Delphi TDateTime object value.
|
| A series of tutorials aimed at the Delphi programmer who seeks a greater understanding of the use of Windows APIs. The focus is on developing a progressively stronger understanding and appreciation for the tools that enable your program to communicate with the Windows Application Programming Interface. |
|
An introduction to Windows APIs for Delphi programmers. This is the first of a series of tutorials that will (hopefully) get you up and running with the API in no time.
|

|
A guide for the Delphi programmer on finding and understanding this invaluable resource for anyone that wants to use the Win32 API.
|
|||
|
The Win32 API makes extensive use of pointers. An understanding of pointers is important for successfully using the Win32 API. This tutorial provides a quick introduction to the concept of pointers in the Object Pascal programming language. A sample program is developed to aid in understanding.
|
|||
| The Win32 API uses its own set of data types. These differ from what we are accustomed to in Object Pascal. This tutorial provides an introduction and list of the common Windows Data Types. The GetLocaleInfo API function is used to illustrate.
|
|||
| An introduction to C for Delphi programmers. This tutorial helps you to understand C source code listings and gain further insight into the use of Windows API functions. A C code snippet that uses an API function is converted into Delphi's Object Pascal.
|
|||
| When you use FindFirst, FindNext, FindFirstFile or FindNextFile the system returns information about files including the creation, last accessed and modified data in UTC format. This tutorial explains how to convert the UTC format times to Delphi TDateTime values.
|
|||
| Using FindFirstFile and FindNextFile | Explores the FindFirstFile and FindNextFile API functions and the WIN32_FIND_DATA structure.
|
||
| The Windows ExtractIcon, ExtractIconEx and ExtractAssociatedIcon API functions can be used to extract icons from files. This tutorial explores those functions and provides a few examples.
|
|||
| This tutorial explains single-byte, multi-byte and Unicode characters and documents the MultiByteToWideChar API function.
|
These sample code snippets and functions perform a particular task.
| A function to determine the full path and file name which contains the icon associated with a particular file.
|
|||
| A function to determine the full path and file name which contains the executable associated with a particular files open command.
