问题 Why don't Windows Shell (cmd.exe) built-in commands read from stdin? (or so it seems) Example: echo bar | set /p foo= 回答1: SET /P does read the input from the pipe, but it doesn't do any good because both sides of the pipe are executed within new cmd.exe processes. So the newly defined variable is lost once the pipe sub-processes terminate.

If I trap WM_LBUTTONDOWN and show my context menu it works fine. But then when someone double-clicks the icon, it first shows my context menu and

问题 I built a virtual filesystem (not a namespace extension) for Windows which acts as a frontend of our document management server consisting of files and folders. In order to be able to display some metadata of the DMS objects in Windows Explorer as additional selectable columns, I successfully provided properties to the Windows Property System by implementing a COM Property Handler. Wheras normal property handlers focus on specific file types for which they feel responsible, my Property

问题 I’m trying to get a progress dialog to display for my copy operation in some sample code. I’m using IFileOperation because I found that using SHFileOperation will not display a progress dialog if the files have already been copied to the target location. My hope is that IFileOperation is a little more sophisticated and can handle that situation. Here’s the sample code I’ve tried…. CComPtr<IOperationsProgressDialog> opProgressDlg; HRESULT hr = opProgressDlg.CoCreateInstance(CLSID

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.

问题 Notepad++ automatically adds a shell shortcut so that when you're in Windows Explorer, you can right-click on a file and select "edit with Notepad++". How can I do the same with emacs?
