delphi教程，内容很全面的教程，学习它需要花时间和精力，初学者学习它最好多问问身边的高手，里面的内容非常精细

delphi第三方控件的安装与删除详解 包含自定义控件的安装与删除

delphi2007之前支持PNG格式图片

Delphi调用明华RD系列读卡器开发范例，包含10种IC卡类型的开发例子。

Delphi远控源码，是在04年发布的，不过源码实现的功能太强大了，只是TServerSocker控件就实现了强大的功能。

初学者有时候对于控件的安装会触手无策，特别是比较新的Delphi10.3.1资料较少，自定义控件安装教程（图文）可以一步一步的教你整个安装过程。

delphi线程池单元文件uThreadPool.pas，用法如下 type TRecvCommDataWorkItem=class(TWorkItem) public // updatetime,addtime:TDateTime; // orderid,ordertype,urljson,loadcount,savepath:string; url,Filename:string; total,order:Integer; _orderid:string; failedcount:Integer; IFCoverFile:Boolean; // 线程处理请求时触发的事件 procedure DealwithCommRecvData(Sender: TThreadsPool; WorkItem: TWorkItem; aThread: TProcessorThread); // 线程初始化时触发的事件 procedure TProcessorThreadInitializing(Sender: TThreadsPool; aThread:TProcessorThread); // 线程结束时触发的事件 procedure TProcessorThreadFinalizing(Sender: TThreadsPool; aThread:TProcessorThread); //任务队列空时触发的事件 procedure TQueueEmpty(Sender: TThreadsPool; EmptyKind: TEmptyKind); end; 先声明一个类 然后用法 FThreadPool := TThreadsPool.Create(nil); // 创建线程池 FThreadPool.ThreadsMin := 10; // 初始工作线程数 FThreadPool.ThreadsMax := 100; // 最大允许工作线程数 AWorkItem := TRecvCommDataWorkItem.Create; ISAllOverLoad:=False; AWorkItem.url:=urljson; AWorkItem.order:=i; AWorkItem.total:=JA.Count; AWorkItem.Filename:=savefilepath; AWorkItem._orderid:=orderid; AWorkItem.IFCoverFile:=IFCoverFile; FThreadPool.AddRequest(AWorkItem,True); // 向线程池分配一个任务 FThreadPool.OnProcessRequest := AWorkItem.DealwithCommRecvData; FThreadPool.OnThreadInitializing := AWorkItem.TProcessorThreadInitializing; FThreadPool.OnThreadFinalizing := AWorkItem.TProcessorThreadFinalizing; FThreadPool.OnQueueEmpty := AWorkItem.TQueueEmpty; 仔细看下线程池单元的函数说明轻松搞定。 procedure TRecvCommDataWorkItem.TQueueEmpty(Sender: TThreadsPool; EmptyKind: TEmptyKind); begin if EmptyKind=ekProcessingFinished then begin try if Assigned(geturl) then //存在的bug 如果下载文件存在的不行 begin //Sleep(200); //激活线程可能会发生在 休眠之前！！ ISAllOverLoad:=True; if geturl.Suspended then //只有线程休眠了 才应该激活线程 否则不应该激活 geturl.Resume; end; finally end; end; end;

SynPDF ====== Synopse PDF engine is a fully featured *Open Source* PDF document creation library for Delphi and FPC, embedded in one unit. It's used e.g. in our [*mORMot* framework](https://github.com/synopse/mORMot), for creating PDF files from generated reports. But you can use it stand-alone, without our main ORM/SOA framework. If you download the whole *mORMot* source code, you do not need this separate package: ensure you get rid of any existing separated *SynPDF* installation, and use the PDF units as available in the main *mORMot* trunk. This *SynPDF* distribution/GitHub account targets only people needing PDF writing, without other *mORMot* features. Features -------- * Pure Delphi code, with no external .dll, and adding very small code size to your executable; * Targets Delphi 5 up to Delphi 10 Seattle (and latest version of FPC), for Win32 and Win64 platforms, with full source code provided; * Includes most vectorial drawing commands, including text,lines or curves; * Renders bitmaps, and metafiles (even most .emf files with clipping and regioning); * Introduce metadata, bookmarks and outline information; * Produce very small .pdf files; * Optionally [encrypt and secure the .pdf content](http://blog.synopse.info/post/2013/06/19/SynPDF-now-implements-40-bit-and-128-bit-security) using 40 bit or 128 bit keys; * Fast file generation with low memory overhead (tested with several thousands of pages); * Access a true VCL TCanvas instance to create the PDF content; * Optionally embed True Type fonts subsets; * Unicode ready, even with pre-Unicode versions of Delphi, including advanced [Uniscribe Glyph shading and Font fallback](http://blog.synopse.info/tag/Uniscribe); * Can publish PDF/A-1 archive files; * Used in a lot of applications, with regular enhancements, mainly from active end-users; * Licensed under a [MPL/GPL/LGPL tri-license](http://synopse.info/forum/viewtopic.php?id=27). Sample code ----------- In fact, you have at least three ways of generating pdfs using the library: * [Directly call](http://synopse.info/forum/viewtopic.php?pid=370#p370) of a `TPdfCanvas` as published by a `TPdfDocument` instance - this is the most direct but also more difficult way of rendering; * [Use regular VCL `TCanvas` methods](http://synopse.info/forum/viewtopic.php?pid=1909#p1909) thanks to `TMetaFile` support - see `TPdfDocumentGDI.VCLCanvas` property and the `TPdfCanvas.RenderMetaFile` method - this is very easy if you want to use "regular" `TCanvas` methods to draw the page content, especially if you have some existing printing code; * [Use `TGDIPages` of the supplied `mORMotReport.pas` unit](http://blog.synopse.info/post/2010/06/30/Making-report-from-code) (extracted from our *mORMot* ORM/SOA framework) to easily create the content from code, with some report-oriented methods (including complex rtf with `TGDIPages.AppendRichEdit`) - for basic reporting features, it is pretty much the solution. The 2nd and 3rd ways are preferred, for most applications. Documentation

针对Delphi C++的反编译工具。它可以反编译出Delphi C++程序的类信息、窗体信息等等。。。
