小编Myt*_*ush的帖子

我正在使用composer(http://getcomposer.org/)来管理Symfony2(symfony v 2.1.3)中的已安装捆绑包.作曲家的版本是de3188c.

我有问题,当我将新的bundle添加到composer.json并执行它时,显示有关更新依赖项的消息,然后下载它们的时间非常少.

我在composer.json中有这些数据(见下文),执行时间大约是20分钟!互联网连接足够快我可以非常快速地下载大文件...

是否有任何技巧可以让它更快？

我想编写c#应用程序,它将在一些正在运行的应用程序之间切换.它应该像Windows中的Alt + Tab一样执行确切的功能.我使用SetForegroundWindow()Windows API中的函数,但如果在Windows任务栏上最小化应用程序,则它无法正常工作.所以我添加了ShowWindow()功能,但有一个问题是我无法以用户设置的原始大小显示窗口.

[DllImport("user32.dll")]
public static extern bool SetForegroundWindow(IntPtr hWnd);

[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

示例:我最大化窗口,然后将其最小化到任务栏中.我打电话的时候:

ShowWindow(processWindowHandle, ShowWindowCmd.SW_NORMAL);
WindowsApi.SetForegroundWindow(processWindowHandle);

窗口未最大化.我尝试使用ShowWindowCmd.SW_NORMAL参数,但结果相同.

我正在使用c#开发metro应用程序,我正在使用async并等待关键字来创建make metro异步操作(下载数据等).我总是显示模态"请等待"对话框.我想在此模态对话框中添加"取消"按钮以允许取消后台操作.但我不知道如何取消处理任务...有没有任何示例如何做到这一点？

这是我的任务的例子:

// Starts task
public void StartTask()
{
    // show the modal dialog with progress
    _progressDialog.IsOpen = true;
    _progressDialog.CancelClick += ProgressDialog_CancelClick;
    await ToWork();
    _progressDialog.IsOpen = false;
}


// Task which takes some seconds
private async Task DoWork()
{
   await DownloadData();
   await ProcessData();
}

// Cancel task
private void CancelClick(object sender, RoutedEventArgs e)
{
    // hide the modal dialog with progress        
    _progressDialog.IsOpen = false;
    // TODO: Cancel task
    GoBack(this, e);
}
