visifire 5.0.2 破解和修改方法原理+实践

在研究Visifire图表应用2-更改图例位置时一不小心就发现visifire的水印可以通过代码取掉，现上最终效果图:

过程是这样的，和Visifire图表应用2-更改图例位置一样在写Rendered事件时发现了一个小秘密

还是官方示例DateTimeAxis

原代码:

public void CreateChart(){Chart chart = new Chart();……省略…..elementHost1.Child = chart;}修改代码:public void CreateChart(){Chart chart = new Chart();……省略…..chart.Rendered += new EventHandler(chart_Rendered);elementHost1.Child = chart;}

加断点，调试，鼠标移动到c上然后点放大镜图标就会出现下图

哈哈，两个水印都在这里了，通过调试知道索引一个是10， 一个是11

代码改成这样:

void chart_Rendered(object sender, EventArgs e){var c = sender as Chart;var legend = c.Legends[0];var root = legend.Parent as Grid;var stackPanel=root.Children[11] as StackPanel;var textBlock1 = stackPanel.Children[0] as TextBlock;textBlock1.Text = "";}效果:

代码继续改为:

void chart_Rendered(object sender, EventArgs e){var c = sender as Chart;var legend = c.Legends[0];var root = legend.Parent as Grid;var stackPanel=root.Children[11] as StackPanel;var textBlock1 = stackPanel.Children[0] as TextBlock;textBlock1.Text = "";var border = root.Children[10] as Border;var textBlock2 = border.Child as TextBlock;textBlock2.Text = "";}效果：

哈哈，如果不要水印，代码:

void chart_Rendered(object sender, EventArgs e){var c = sender as Chart;var legend = c.Legends[0];var root = legend.Parent as Grid;root.Children.RemoveAt(10);root.Children.RemoveAt(10);}效果:

，今日的执着，会造成明日的后悔。
