aPLib is a 32-bit compression library based on the compression algorithm
used in aPACK (my executable packer). aPLib is an easy-to-use alternative
to many of the heavy-weight compression libraries available.

SelectionDemo also has code (not included in the preceding snippet) that changes the table s selection orientation. By changing a couple of boolean values, you can make the table allow either column selections or individual cell selections, instead of row selections.

The code is fairly straightforward, except perhaps for the call to convertColumnIndexToModel. That call is necessary because if the user moves the columns around, the view s index for the column doesn t match the model s index for the column. For example, the user might drag the Vegetarian column (w ...

pb datawindow 技巧
例子：
使DataWindow列只能追加不能修改
如何使DataWindow中的数据只能追加新记录而不能修改，利用 Column 的 Protect 属性可以很方便的做到这一点，方法如下：
将每一列的 Protect 属性设置为：
If( IsRowNew(), 0, 1) )
在 PowerScript 中可以动态修改 Protect 属性：
dw_1.Modify("column_name_h ...
其他 对一个运输商来说要把货运到收货地点选择最短的路线运输是其实现最大利润的要求
对一个运输商来说要把货运到收货地点选择最短的路线运输是其实现最大利润的要求，那么怎样选择最短的运输路线呢？在运输交通图中，我们设每一个城市为一个结点（vertextype类型）点并把他们分别用关键字代表（关键字int key ），也就是说把每个城市给出一个整数编码；一个城市直接到另一个城市的交通路线为边且这两个城市为 ...

人工智能/神经网络 BP神经网络分类器 程序有两种运行状态
BP神经网络分类器
程序有两种运行状态，一个是学习，另外一个是分类。在学习状态下，在Dos命令符下输入bp learn，便开始学习了，学习的结果放在weight.dat中；在工作状态下，在Dos命令符下输入bp work，便开始识别classfyme.dat中的数据了，识别完成后，结果放在results.dat中。在bp运行的任何一种状态下，都不能手工打开W ...
