TBetterADODataSet是直接继承与delphi的TADODataSet，主要是 1.修正了很多TCustomADODataSet，甚至ADO本身的Bug 2.实现了Borland未来得及实现的功能 3.扩展了原有的功能 BetterADODataSet能够减少%50的书写代码，使用BetterADODataSet使delphi上的ADO更简单， 成为真正的RAD-TBetterADODataSet is the direct successor to the TADODataSet with delphi, is a principal. This amendment to a lot, even ADO own Bug 2. Borland did not realize the time to realize the function of three. Expansion of the original features can reduce P BetterADODataSet writing code, so delphi BetterADODataSet use the more simple ADO as real RAD

Delphi渐变圆形的实现方法，RGB色环空心绘制演示源码： 　　oBmp := TBitmap.Create; //为了代码整齐就不写try了 　　oBmp.PixelFormat := ABitmap.PixelFormat; 　　oBmp.Width := ABitmap.Width; 　　oBmp.Height := ABitmap.Height; 　　BitBlt(oBmp.Canvas.Handle, 0, 0, oBmp.Width, oBmp.Height, ABitmap.Canvas.Handle, 80, 80, SRCCOPY); //要拷贝的位图 　　oRgn := CreateEllipticRgn(0, 0, 100, 100); //创建圆形区域 　　SelectClipRgn(ABitmap.Canvas.Handle, oRgn); //选择剪切区域 　　ABitmap.Canvas.Draw(0, 0, oBmp); //位图位于区域内的部分加载

delphi字符串加密,可以将delphi源代码中的字符串作加密处理，发布程序前可以用。虽然加密算法简单，但因为密码是随机生成的，所以还是可以起到一定的保护作用的。-delphi string encryption, can be delphi source code of the string for encryption processing, pre-release procedure can be used. Although the encryption algorithm is simple, but because the password is randomly generated, it can still play a protective role.

原生Pascal代码实现的读写JPEG文件的组件。完整源码。 This software component contains a fully object oriented Pascal implementation that allows to read and write Jpeg files. You can use this software to read and write Jpeg images from files or streams. It supports baseline and progressive Jpeg, support for metadata, as well as all conceivable lossless operations.(Original Pascal code of the components to read and write JPEG files.
