问题 My company builds an MFC application that runs on Windows XP. One of our customers has reported a crash in this application that occurs when it opens a Common File Dialog to allow the user to save a log file. We haven't observed this crash on any of our integration systems. The customer provided us with a crash dump which shows that the program is trying to read from some inaccessible memory at address 160b2d48. The address appears to be from the code section of the address space, as there

问题 I am researching the development of an add-on for Windows Explorer that will add some enhancements to the WebDAV therein, and to that end I'm looking for a good, reliable way to force a DLL to be loaded with Windows Explorer in XP/Vista/Win7 32- and 64-bit OSes. I seem to recall that a BHO would be loaded by Windows Explorer in the same way that it is in IE, but my initial tests of this are negative on Vista 64. It's highly possible I'm just doing something wrong there and will look into that

问题 I tried to implement a custom ShellExtension in Windows 8.1 . Found that really good SharpShell tutorial. [ComVisible(true)] [COMServerAssociation(AssociationType.AllFiles)] public class CountExtProvider : SharpContextMenu { protected override bool CanShowMenu() { // We will always show the menu. return true; } protected override ContextMenuStrip CreateMenu() { // Create the menu strip. var menu = new ContextMenuStrip(); // Create a 'count lines' item. var itemCountLines = new

问题 I am trying to extend whindows explorer (NOT IE) with a customized panel in C++, which should look like this: and here's a similar question I found (in C#) : Similar question The question is of C# and already got an answer. But I myself find the answer is a bit too brief for me to follow, here's what I got: I should implement a BHO object the BHO object should implemet IObjectWithSite and IDockingWindow In SetSite method, call QueryInterface to get the pointer of service provider, then call

问题 I'm trying to implement a shell namespace extension, for the sole purpose of overriding the thumbnail handler ( IExtractImage ) in a specific folder. I want everything else to be the same as in a normal folder , and I'd rather not have to reimplement everything that is done in the default implementation of IShellFolder ... So, is it possible to inherit from this default implementation? If so, how? Using composition would also be an acceptable solution, but how can I get an instance of the

问题 I am developing namespace extension which gives a virtual view of files on a server. In this view, I need to provide different states(in use, offline, out of sync, etc) of a file using overlay icons. I was read through article implementing overlay handler, and thought I will try to handle this in one of our overlay handlers, which implement IShellIconOverlayIdentifier interface. I see that IShellIconOverlayIdentifier::IsMemberOf(), and other functions are called only when I access files on

问题 I'm writing a Windows shell extension in C# using EZShellExtensions.NET. I contribute a context menu that shows dialogs. Suppose that I show an Explorer window (A). Then I use the context menu to show non modal window (B). In Windows XP and Windows Vista, when I close A, B is closed (I want this behavior). However, in Windows 7, when I close A, B is not closed but it doesn't respond to events. My questions are: Do you know why Windows 7 manage the showed form as a child form? Is there a way

问题 Currently, my property handler provides properties that can be displayed in Windows Explorer columns of type String . My goal is to extend the handler by a property of (display) type Icon , that can be added as a column to the details view of Windows Explorer. In this column, an icon should be displayed for each file item, e. g. the icon could represent a specific state of the file out of several possible states. However, I did not manage to assemble the necessary parts of creating a property

问题 When Winrar installed, and user right click on a file, a new mune item exists: "Add to Archive..." How can do like this for my application? 回答1: This can be done by adding a shortcut (context) menu handler.
