How do I create a Delphi Class library



What are some options for creating a Delphi Class library?



I have a class TWidget that is used in multiple programs. Currently, I have each program link to commonUnitWidget.pas source code file. However when TWidget changes, I am forced to recompile and rerelease all programs referencing it.



I am not very familiar with C#, but I believe they have a Class Library concept which allows classes to be encapsulated and shared across programs. I think this is what I am looking for in Delphi.



In Delphi I have made some DLLs, but I do not know if they can be used effectively as a class library. It seems packages are the way to go, and I should make my own package in the spirit of the RTL package. I don't know what sort of "gotchas" I'll run into, versioning, etc. However, before I go too far down the wrong rabbit hole I thought it best to humbly ask how this is approached by others.



Thanks!





Sounds like you're looking for Delphi Packages. For example: thoughtco.com/bpl-vs-dll-1058181

Yet again downvotes without comments. What was that about stackoverflow becoming more user friendly?

@dummzeuch: while I also don't like it, people can downvote without leaving a comment. It is quite common on SO.

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...
