问题 I'm working with WPF KeyDown event (KeyEventArgs from Windows.Input). I need to recognize when user pressed F1 alone and Ctrl+F1. private void Window_KeyDown(object sender, KeyEventArgs e) { if (e.Key==Key.F1 && Keyboard.IsKeyDown(Key.LeftCtrl)) { MessageBox.Show("ctrlF1"); } if (e.Key == Key.F1 && !Keyboard.IsKeyDown(Key.LeftCtrl)) { MessageBox.Show("F1"); } } My problem is that when I press Ctrl+F1 plain F1 messagebox would fire too.

问题 I have a WinForms project from which I want to open a WPF window from a WPF user control project. But when I create an instance of the WPF window and call Show(), the bootstrapper isn't loaded. In an Windows Application, it's located in the App.xaml, but an user control project doesn't have this. What can I do?

问题 I am using D3DImage to display a sequence of frames that are rendered unto the same Direct3D Surface one after the other. My current logic is thus: Display last rendered frame (i.e.D3DImage.Lock()/AddDirtyRect()/Unlock()) Start rendering next frame Wait for next frame to be ready and that it's time to display it Display last rendered frame ... The problem with this approach is that when we are done calling Unlock() on D3DImage, the image isn't actually copied, it's only scheduled to be copied

问题 I am making UI as shown in picture below. It is a DataGrid, Itemsource is bound to a List. I cannot set ColumnSpan for the TextBox .
