contextmenu

问题 I have an application that lists files, and I allow the user to right-click on a file and my application shows the Windows context menu for the selected file. I use SHParseDisplayName to get a pidl for a filename. Then I bind to the parent object: IntPtr pidlLast = IntPtr.Zero; SHBindToParent(pidl, typeof(IShellFolder).GUID, out oShellFolder, out pidlLast); After I have the parent I can get build the context menu: IntPtr result = IntPtr.Zero; IShellFolder shellFolder = (IShellFolder

问题 So the idea is to make an encryption software which will work only on .txt files and apply some encryption functions on it and generate a new file. To avoid the hassle of user having to drag-and-drop the file, I have decided to make an option similar to my anti-virus here. I want to learn how to make these for various OS, irrespective of the architecture :) What are these menus called? I mean the proper name so next time I can refer to them in a more articulate way How to make these? My

问题 In the Chrome extension I'm working on right now, there's a situation where if the user right-clicked on this link: <a href="http://www.google.com">Hello</a> and selected a certain option from my extension's context menu, I need the string "Hello" to be captured in some form. As the Context Menus API shows, it's easy to capture text from a right-clicked selection or the actual URL of the hyperlink (in this case, Google.com) , since these appear in OnClickData, but I'm not sure how I would

问题 Basically I want to show a different context menu when the user short clicks or long clicks on a cell in the grid view. The issue I have is that if the user short clicks the OnItemClick listener is called and I see the debugger reach the code that shows the context menu but rather than moving from there to onCreateContextMenu it goes to onItemLongClick. I have tried using a Boolean to prevent the long click code being executed which does prevent that code being executed, however even when

问题 In my .NET applications, context menus look like the left one. How can I apply the Windows 7 style on them in order to make them look like the right one? 回答1: Right-click the tool box, Choose Items. Tick "ContextMenu", the one with Namespace = System.Windows.Forms and Directory = Global Assembly Cache. This .NET 1.x component is distinct from ContextMenuStrip, it uses native Windows menus. You'll lose some capabilities, I doubt you care. You'll need to write a line of code to assign the menu,

问题 I have a context menu - problem is I need it to only open when a listviewitem is clicked. Right now it will open if I click anywhere in the listview or in the header. <ListView> <ListView.ContextMenu> <ContextMenu> <MenuItem Header="More Info" Command="{Binding MoreInfo}" /> </ContextMenu> </ListView.ContextMenu> <ListView.View> <GridView> <!-- columns and stuff here --> </GridView> </ListView.View> </ListView> I have tried adding the ContextMenu as a resource and applying it as a style, but

问题 I'm using Eclipse IDE on Ubuntu. My app offers encryption services and I want to integrate it into the client OS. My question is: Is there a way to put my app programmatically into the context menu (right-click options) of the file manager, irrespective of the file manager a person is using? I would also like to know if there is any way I could do this on Windows explorer as well. But my guess is that it involves adding values to the registry and can be easily achieved. So, is there a general

问题 My user control context menu visibility can't bind a dependency property. Any idea?
