[1]通过 IHttpModule interface 来实现 aps.net 页面部分全局更改

来源: 发布时间: 2013-10-28

有时候。比如。在所有页面下方实现一个输出当前时间。方便查看时间

mono 测试已过。其他未测试

这时候可以通过 IHttpModule 接口来全局实现。

IHttpModule --->request ---> Http Module 来挂钩

so:

1.配置文件里面，指向这个类。当request访问的时候。初始化这个类

</httpModules>

2 simpleModule 首先要继承IHttpModule .然后必须要 Init和Dispose 实现

public class SimpleModule : IHttpModule
{
private HttpApplication objApplication = null;

public void Dispose()
{
}
public void Init(System.Web.HttpApplication context)
{
objApplication = context;
context.EndRequest += new EventHandler(context_EndRequest);
}
void context_EndRequest(object sender, EventArgs e)
{
string message =
string.Format("<br/>现在时间为{0}", System.DateTime.Now.ToString());
objApplication.Context.Response.Write(message);
}
}

这时，访问任何页面，页面下面就会出现时间。

[3]WPF TextBox输入显示提示

来源: 发布时间: 2013-10-28

在网上支付输入银行卡的时候，经常看到输入的数字会放大和提示。

下面是WPF版的一个例子。

Code public class ZoomTextTooltip : FrameworkElement
{
public object ZoomText
{
get { return (object)GetValue(ZoomTextProperty); }
set { SetValue(ZoomTextProperty, value); }
}

// Using a DependencyProperty as the backing store for ZoomText. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ZoomTextProperty =
DependencyProperty.Register("ZoomText", typeof(object), typeof(ZoomTextTooltip), new UIPropertyMetadata(null,
(o, args) =>
{
var textBox = args.NewValue as TextBox;
if (textBox == null)
return;
var zoomTextTooltip = o as ZoomTextTooltip;
if (zoomTextTooltip == null)
return;
var popup = new Popup();
var textBlock = new TextBlock
{
Text = textBox.Text,
FontWeight = FontWeights.Bold,
FontSize = zoomTextTooltip.CustomFontSize,
Background = zoomTextTooltip.CustomBackground,
Foreground = zoomTextTooltip.CustomForeground
};
var binding = new Binding();
binding.Source = textBox;
binding.Path = new PropertyPath("IsKeyboardFocused");
BindingOperations.SetBinding(popup, Popup.StaysOpenProperty, binding);

var inputText = zoomTextTooltip.AddBlockString(textBox.Text.Trim(), zoomTextTooltip.BlockCount);
textBlock.Text = inputText;
popup.Child = textBlock;

textBox.GotFocus += (sender, eventArgs) =>
{
popup.PlacementTarget = textBox;
popup.Placement = PlacementMode.Top;
popup.IsOpen = true;
};
textBox.TextChanged += (sender, eventArgs) =>
{
var addBlockString = zoomTextTooltip.AddBlockString(textBox.Text.Trim(), zoomTextTooltip.BlockCount);
textBlock.Text = addBlockString;
};

textBox.LostFocus += (sender, eventArgs) =>
{
popup.IsOpen = false;
};
}
));
//字符串截取
private string AddBlockString(string input, int count)
{
if (count == 0)
return input;
var blockinput = string.Empty;
var length = Math.Ceiling((double)input.Length / count);
for (int i = 0; i < length; i++)
{
var firstStart = i * count;
var endString = input.Length - firstStart;
if (endString < count)
{
blockinput += input.Substring(firstStart);
}
else
{
blockinput += input.Substring(firstStart, count);
blockinput += " ";
}

}
return blockinput;
}
public double CustomFontSize
{
get { return (double)GetValue(CustomFontSizeProperty); }
set { SetValue(CustomFontSizeProperty, value); }
}

public static readonly DependencyProperty CustomFontSizeProperty =
DependencyProperty.Register("CustomFontSize", typeof(double), typeof(ZoomTextTooltip), new UIPropertyMetadata(12.0));

public Brush CustomBackground
{
get { return (Brush)GetValue(CustomBackgroundProperty); }
set { SetValue(CustomBackgroundProperty, value); }
}

public static readonly DependencyProperty CustomBackgroundProperty =
DependencyProperty.Register("CustomBackground", typeof(Brush), typeof(ZoomTextTooltip), new UIPropertyMetadata(Brushes.White));

public Brush CustomForeground
{
get { return (Brush)GetValue(CustomForegroundProperty); }
set { SetValue(CustomForegroundProperty, value); }
}

public static readonly DependencyProperty CustomForegroundProperty =
DependencyProperty.Register("CustomForeground", typeof(Brush), typeof(ZoomTextTooltip), new UIPropertyMetadata(Brushes.Black));

public int BlockCount
{
get { return (int)GetValue(BlockCountProperty); }
