一、WPF 中获取和设置鼠标位置
方法一:WPF方法
Point p = Mouse.GetPosition(e.Source as FrameworkElement); Point p = (e.Source as FrameworkElement).PointToScreen(pp);
方法二: API方法

/// <summary>
/// 设置鼠标的坐标
/// </summary>
/// <param name="x">横坐标</param>
/// <param name="y">纵坐标</param> [DllImport("User32")] public extern static void SetCursorPos(int x, int y);
public struct POINT
{
public int X;
public int Y;
public POINT(int x, int y)
{
this.X = x;
this.Y = y;
} } /// <summary>
/// 获取鼠标的坐标
/// </summary>
/// <param name="lpPoint">传址参数,坐标point类型</param>
/// <returns>获取成功返回真</returns> [DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern bool GetCursorPos(out POINT pt); private void Window_MouseMove(object sender, MouseEventArgs e)
{
POINT p = new POINT();
if (GetCursorPos(out p))//API方法
{
txtStat.Text = string.Format("X:{0} Y:{1}", p.X, p.Y);
}
}

二、 WPF中实现实时更新progressbar
实现实时更新ProgressBar貌似有很多方法,我搜索的很多资料都要用线程,觉得还是有点儿麻烦,最后在国外的技术论坛上看到
一个用代理解决的方法,下面就是我的调试过程:

private delegate void UpdateProgressBarDelegate(System.Windows.DependencyProperty dp,
Object value);
private void Process()
{
//Configure the ProgressBar
ProgressBar1.Minimum = 0;
ProgressBar1.Maximum = short.MaxValue;
ProgressBar1.Value = 0;
//Stores the value of the ProgressBar
double value = 0;
UpdateProgressBarDelegate updatePbDelegate = new UpdateProgressBarDelegate(ProgressBar1.SetValue);
//Tight Loop: Loop until the ProgressBar.Value reaches the max
do
{
value += 1;
Dispatcher.Invoke(updatePbDelegate,
System.Windows.Threading.DispatcherPriority.Background,
new object[] { ProgressBar.ValueProperty, value });
}
while (ProgressBar1.Value != ProgressBar1.Maximum);
}

前台:
<ProgressBar Grid.Row="1" Height="20" Width="200" Margin="0,4,0,0" Name="ProgressBar1" HorizontalAlignment="Center" VerticalAlignment="top" />
效果:
方法二:使用定时器

public Window1()
{
InitializeComponent(); DispatcherTimer _mainTimer = new DispatcherTimer();
_mainTimer.Interval = TimeSpan.FromSeconds(1);
_mainTimer.Tick += new EventHandler(_mainTimer_Tick);
_mainTimer.IsEnabled = true; }


void _mainTimer_Tick(object sender, EventArgs e)
{
if (progressBar2.Value == progressBar1.Maximum)
progressBar2.Value = 0; progressBar2.Value++;
}
