问题 I am working on learning DirectX 12 from some examples but I am having trouble understanding what does the ComPtr.As() method does. ComPtr<ID3D12Device> device; ComPtr<ID3D12Device> device2; // Do Stuff with Device device.As(&device2); // What does this do? 回答1: Where did you find this example code? It looks fishy. This is kind of a nonsense use of As . It's equally silly if you expand it to the underlying QueryInterface : hr = device->QueryInterface( IID_PPV_ARGS(device2) ); In fact, your

问题 How can I distinguish IE shell windows from non IE shell windows? I've got the following snippet of code (Lot's or extraneous logic removed) that uses the ShellWindows object to scan the open windows to see what URL the user is browsing, with the intention of doing something if they have browsed to a particular URL: // Shell Windows object obtained in another method private ShellWindows shellWindows = new ShellWindows(); ... // iterate through all windows foreach (SHDocVw.IWebBrowser2

问题 I have this BHO which I successfully exposed method to JS from it using this thread: Calling BHO method from Javascript?. When I open a CAxWindow in order to host HTML docs, I'd like to use this exported method but it seems that it doesn't work for that window as well. I tried to make a custom class like: class Bubble: public CAxWindow, public IDispEventImpl<1, Bubble, &DIID_DWebBrowserEvents2, &LIBID_SHDocVw, 1, 0> { public: BEGIN_SINK_MAP(Bubble) SINK_ENTRY_EX(1, DIID_DWebBrowserEvents2,

问题 I've created a COM object using NATIVE c++ - both COM object and it's native client works perfectly. the next step was to implement the COM object as a out of process COM server( hosted by the dllhost process. I followed the standard registry-change procedure(http://support.microsoft.com/kb/198891) and both client and COM server started to work properly under the dllhost.exe process. However, I can see that sometime the host server crashes and the dllhost.exe pop up a message stating error

问题 There's something weird about get_Caller(Type.Missing) method. It returns a negative integer, -2146826265 , instead of the Range object as it should. Has anyone come across this issue before? Why is that and how should I solve it? Thanks. Excel.Range range = (Excel.Range) application.get_Caller(System.Type.Missing); The above code would fail if I try to explicitly user type Excel.Range . The error message says, 'Cannot convert type 'int' to 'Microsoft.Office.Interop.Excel.Range'. EDIT: The

问题 Either I don't understand COM objects, either it's all that confusing. I frequently 'create' , 'dispatch' COM objects - either in Python, either in VB ( Obj = win32com.client.Dispatch('Visum.Visum') or Obj = CreateObject("Excel.Application") respectively). That's easy, obvious and everything's fine. But how can I: a) connect to COM object which is already running b) get list of running processes which are COM objects in VB what is the reference, and additional info on: CreateObject command.

问题 I'm trying to enhance a CFileDialog, and we're using the older version of it (the non-vista one that doesn't use IFileDialog). The older one does allow me to obtain an IShellBrowser, as well as (from that) the active IShellView. What I cannot seem to come up with is a way to get "What IShellFolder does that IShellView refer to?" Equally useful would be "What is the current folder that IShellBrowser has made active?" 回答1: I think I may have solved it in a round about fashion: I'm using CDM
