问题 How can I access the protocol activation arguments in a Winforms app that's converted into a UWP app? The problem is that the OnActivated method is absent so I can't get the IActivatedEventArgs . 回答1: I'm assuming you want to handle file types in which case you can check Environment.GetCommandLineArgs() as normal for arguments. The second argument will be the file or protocol activated. 回答2: How can I access the protocol activation arguments in a Winforms app that's converted into a UWP app?

Right now I have in App.xaml.cs protected override void OnStartup(StartupEventArgs e) { if (myprog.Properties.Settings.Default.UpgradeRequired) { myprog.Properties.Settings.Default.Upgrade(); myprog.Properties.Settings.Default.UpgradeRequired = false; myprog.Properties.Settings.Default.Save(); } With UpgradeRequired as a bool

问题 I have created a GridView which gets data through data binding. What I want to do next is make the GridView item width dynamic according to the Screen Size ( Like the ones they have done in the Windows 10 news, sports app, etc. ) So far I have done it successfully for minimum window width 0 using visual state manager by setting the horizontal alignment to stretch, but I am not being able to continue this for other wider window sizes. Any kind of help for sorting this out will be appreciated.

问题 I have a Gridview where I want items to be grouped and flow horizontally. The groups are still vertically scrolling. How can I fix this? 回答1: The ItemsPanelTemplate is the one that determines the layout of items. Usually an ItemsWrapGrid is used for a GridView. That control has a property called MaximumRowsOrColumns. Set that to the number of rows you want as a max on a page. The data is then always in a horizontal layout. You can add something like this: <GridView.ItemsPanel>

问题 I've been trying to figure out why the UI was blocking from a ViewModel method, and realized that this part of the code: await Task.WhenAll(getOutput1(), getOutput2()); was the problem. I managed to unblock the UI by using: await Task.WhenAll(Task.Run(() => getOutput1()), Task.Run(() => getOutput2())); getOutput1() and getOutput2() are both async with Task return types in the ViewModel, and the code is called from the View. What's the difference with calling Task.WhenAll when I call Task.Run(

问题 I'm trying to make a UWP app which can export a file saved in his own storage into the document library. In Package.appxmanifest I've inserted the following lines: <uap:Capability Name="picturesLibrary" /> <uap:Capability Name="documentsLibrary" /> The code to get the path is this: StorageFolder storageFolder = await KnownFolders.GetFolderForUserAsync(null /* current user */, KnownFolderId.DocumentsLibrary); string path = storageFolder.Path + "\\" + fileName; The code to save the file is this
