问题 Used code I found on SO to use the COM based Acrobat Reader to display PDF via hosting in a WindowsFormsHost. It displays the PDF fine. Two problems: When I load the PDF the control AxAcroPDFLib.AxAcroPDF takes focus I want focus to remain on the prior When AxAcroPDFLib.AxAcroPDF has focus it eats the Hot Key (N) The ALT key does not even underline the N. Even if the user selects the AxAcroPDFLib.AxAcroPDF I would like the Hot Keys to work. I understand this is COM and Adobe in WPF and there

问题 I'm creating an application that will heavily use PDF file viewing. Is there a difference/advantage in using WindowsFormsHost over WebBrowser? WebBrowser is just a line of code versus WindowsFormsHost setup. So, I'm curious if there are any advantages of using WindowsFormsHost? 回答1: WPF WebBrowser control runs in IE protected mode by default, and Adobe PDF Reader plugin is known to have issues with that. Check this question. I'd go with WindowsFormsHost and host PDF Reader ActiveX directly,

问题 In my WPF application, I have a class that serves as a wrapper around QuickTime. It provides all the specific or simplified functionality I need. To function, it needs to create an instance of QuickTime's ActiveX control and place it in a valid Windows Forms window. My app being WPF, the constructor works like this: public VideoPlayerQT(WindowsFormsHost wfHost) { AxQTControl qtControl = new AxQTControl(); wfHost.Child = qtControl; } Now in the main window, I use the player like this: private

问题 I have a WPF project where I maintain video ratio, by placing video control inside a ViewBox. The video control is a WinForms object wrapped inside a WindowsFormsHost. I also added a gridSplitter to resize the ViewBox. It all worked great, until I noticed a strange bug. When I would use the gridSplitter control to minimize the ViewBox close to zero, the video ratio would get screwed up after expanding it again. And when I used gridSplitter to contract the ViewBox all the way down to 0, the

问题 somebody addressed this issue here http://social.msdn.microsoft.com/forums/en-US/wpf/thread/6f9dd3b5-af92-4076-9b4e-1a770dd52f70/ but that was in 2006. i am currently using .net framework 3.5. Is there any better solution for that now. Does anybody know if microsoft has a straight forward solution for this issue in 4.0? 回答1: Yes, this won't work. Quote from this link This is a limitation of using WS_EX_LAYERED and UpdateLayeredWindow(). This form of layered windows does not support child

问题 I have a WPF app that has a WindowsFormsHost in which a 3rd party WinForms control is hosted. Sometimes, because of a bug in the 3rd party WinForms control I get a NullReferenceException . Although I had set up a DispatcherUnhandledException handler I can't catch the exception there and continue the execution. Only in the AppDomain.CurrentDomain.UnhandledException handler I can "catch" it but I cannot do much from then on, the application simply exits. Then I found a stackoverflow question

问题 I have a problem regarding GridSplitter visiblity. In this, whatever I am hosting a Winform DataGridView. The GridSplitter, when dragged is properly visible on other controls. But not on this grid. In fact, whatever I host instead of Datagridview, becomes the topmost control, which makes the GridSplitter hide behind it. <Grid> <Grid.RowDefinitions> <RowDefinition Name="rowForButton"/> <RowDefinition Name="rowForGridSplitter" Height="Auto" MinHeight="81" /> </Grid.RowDefinitions> <Button Grid

问题 I need to animate WindowsFormsHost control. The problem is that I can't see the animation, the window doesn't refresh. If I resize my WPF window during the animation then the transition is visible. I tried putting WindowsFormsHost inside a grid and then animate the grid but the result is the same. I put some other stuff into the grid to make sure that I wrote the animation correctly. Here's some simple application just to test this: <Window x:Class="WpfApplication1.MainWindow" xmlns="http:/
