我想在启动地铁应用程序(按城市启动屏幕上的应用程序磁贴)时从地铁应用程序进入win32桌面。一种方法是在启动metro应用程序时打开文件(例如TXT文件)。我将下面的代码逻辑添加到OnLaunched中,有时它可以打开文件并进入桌面,但有时它不会。有人能帮助我吗? (只需在VS2012中创建一个空白的应用程序)。在启动时从地铁应用程序进入win32桌面
async protected override void OnLaunched(LaunchActivatedEventArgs args) {
// Do not repeat app initialization when already running, just ensure that the window //is active
if (args.PreviousExecutionState == ApplicationExecutionState.Running)
{
Window.Current.Activate();
return;
}
if (args.PreviousExecutionState == ApplicationExecutionState.Terminated)
{
//TODO: Load state from previously suspended application
}
// Create a Frame to act navigation context and navigate to the first page
// var rootFrame = new Frame();
if (!rootFrame.Navigate(typeof(MainPage)))
{
throw new Exception("Failed to create initial page");
}
// Place the frame in the current Window and ensure that it is active
Window.Current.Content = rootFrame;
Window.Current.Activate();
{
string txtfile = @"Assets\a.txt";
var file = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync(txtfile);
if (file != null)
{
bool success = await Windows.System.Launcher.LaunchFileAsync(file);
if (success)
{
}
else
{
}
}
}
}
您是否尝试过创建一个WinForms应用程序,该应用程序在启动时立即退出并启动该应用程序? – PhonicUK
