VC 图书管理系统，基于Access数据库，相对完整版的图书馆系统，运行效果如截图所示，不过要注意，运行需要相关的DLL控件，已为您打包在_dll目录下。本图书系统可以完成用户资料管理，图书资料管理，借阅/还书管理等常用功能。

100%原生的DELPHI编写的ZIP/UNZIP 全功能开发包,包含全部源代码. Delphi 4, 5, 6, 7, 2005, 2006, 2007 and 2009 compatible C++ Builder 4, 5 6, 2007, and 2009 compatible The VCLZip Delphi component allows you to add ZIP and UNZIP capabilites to your application. This component is different from most other "ZIP" development libraries in that it is written in 100% Delphi Object Pascal code and is full featured. There are no DLL's to tote around. This component links right into your application's executable. It is very easy to use. Just SOME of the features include: Create zip files fully compatable with PKZip Completely native Delphi VCL (NO DLLS) Create Disk Spanning and Blocked zip files Delphi 4, 5, 6, 7, 2005, 2006, 2007 and 2009 compatible C++ Builder 4, 5 6, 2007, and 2009 compatible Zip directly from streams to zip files Unzip directly to streams from zip files Stream to Stream zipping and unzipping Unzip directly to memory buffers Zip directoy from memory buffers Create and read Zip and File Comments Create Self Extracting Zip Files (16 bit and 32 bit distributable Windows sfx stubs included (source included for these too) or use your own stubs) Complete support for encrypted files (encrypts as it zips) Save Relative Path information Unzip using Relative Paths (even if zip file wasn't created with relative path info) Use enhanced wildcards Exclude List (tell VCLZip which files not to include (use wildcards too)) NoCompress (STORE) List (tell VCLZip which files to just store (use wildcards too) Set your own temp directory Plenty of events Long filenames, even the 16 bit VCLZip/VCLUnZip Includes comprehensive Zip Utility with source as demo Includes a small stream zipping demo Includes a context sensitive help file Use Unicode filenames, archive names, and pathnames (except for Delphi/BCB 4 and5) . No Royalties! AES Strong Encryption Zip64 capabilities, properties, methods and events: Uncompressed, Compressed, and Archive file sizes can be up to 2^63-1 bytes in length. You can compress up to 2147483647 files into an archive. This is compatible with PKZip's Zip64 format. If a file does not extend beyond any of the original limitations (filesizes of 4 gig or 65535 files) then no Zip64 format information is included in the archive. property isZip64 - tells you when you are working with a zip file that is using Zip64 format. Faster processing due to linking to Zlib 1.2.3 object files for compression and decompression routines. Blocked Zip Files (spanned zip archives split onto hard drive) Compatible with PKZip and WinZip split archives file naming format. For backwards compatability you can tell VCLZip to use the old VCLZip filenaming format by using the BlockMode property

VC 填充图像区域的例子，是针对 平面几何图形填充区域的方法进行示例演示，本示例中将画第一个矩形框，然后填充第一个矩形框，画第二个矩形框，然后填充第二个矩形框，第一个图形和第二个图形有区别，部分区域是重叠的，源码中的方法演示了如何填充这些区域，详细请下载源码参见注释。

VC 实现指定区域的图像填充技术，将规定区域填充成其它颜色，与图像处理紧密相关，有需要的编译一下。

vc++调用pytho,可带返回值,供大家学习测试

Delphi压缩解压控件 VCLZip v3.0，在Delphi中实现快速解压文件、压缩文件时候所用的组件，自带有示例，3.0版本，有些早了，不过比较稳定了。
