问题 This is a long shot but if I could do this it would save me time and a hassle. I have a DirectShow video filter that is a typical external DLL (AX file) that feeds video to Skype. I already know how to use a filter privately. However, I don't know if it's possible to make a private filter, one that is embedded in an EXE and is not an external DLL, discoverable by external programs. As far as I know, the main way DirectShow filters are made visible is via registering them in the Registry as an

问题 I have a COM visible dll suitable for 32 and 64 bit architechtures that I use to add a menu item to the windows explorer context menu. Using "regasm myassembly.dll /codebase" I register the dll and see the new menu item. Great. Unregistering works fine also. Now I want to create a .reg file so I can add the menu item to non development machines. I use "regasm myassembly.dll /codebase /regfile" that produces a reg file that I can import with regedit. The problem is, after importing the .reg, I

问题 I'm updating a VS2010 C++ project to VS2019. The project is importing several tlb files, and for each of these, VS2019 is giving an error that it "cannot open source file" for the .tlh file. One of these is from a DLL that I've also upgraded (written in C#, built and registered OK in VS2019), and 2 others are 3rd party tlb files. Here's an example of the import statement (in my header file)... #import "../ExcelInterop/bin/Debug/ExcelInterop.tlb" raw_interfaces_only, raw_native_types, no

问题 I have a game that uses flash activex component. The problem is I need a specific version of flash. I don't want to register the component over the existing higher version which can cause big security issues. I only want to use it for my application. I've heard about registration free com technology using a manifest file for my application but didn't found any information on using it with flash activex or even its possible. So my question is it possible to us the flash activex component as a

问题 I would like to create a ChemDraw .cdx file from an InChI with Python. This answer gives a solution for cdx --> InChI . The minimal example below cdx_to_inchi works fine, but I could not figure out how I can get inchi_to_cdx to work. import comtypes.client as w32 def cdx_to_inchi(cdx): ChemDraw = w32.CreateObject("ChemDraw.Application") ChemDraw.Visible = False Compound = ChemDraw.Documents.Open(cdx) # opens existing file inchi = Compound.Objects.Data("chemical/x-inchi") print(inchi) ChemDraw

问题 So, I am playing around with ActiveX and C# and ways how both of them can work together. the thing is I have hit the wall right in the beginning with mentioned error. Steps I have followed: In VS2010 I selected MFC ActiveX Control project. Then I added a method "SHORT Multiply( SHORT a, SHORT b);" by clicking the Add method option in the menu that pops when you right click _DProjectname under ProjectnameLib in solution explorer. The code for the method is as follows: SHORT

问题 I am trying to retrieve an IOleCommandTarget reference from a panel control handle, so that I can call IOleCommandTarget.Exec() on it. NativeMethods.IOleCommandTarget target = null; if (GetObjectFromHandle<NativeMethods.IOleCommandTarget>(panel.Handle, out target)) { Guid guidCmdGroup = commandID.Guid; handled = (target.Exec(ref guidCmdGroup, commandID.ID, 0, null, 0) == NativeMethods.S_OK); } private static bool GetObjectFromHandle<T>(IntPtr hwnd, out T value) { Guid guid = typeof(T).GUID;

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 After hours of searching google, with little luck, I'm wondering if anybody knows how to either hide the cursor, or set a custom cursor (which could be made blank) in Windows when dragging and dropping. I'm writing a program which draws its own mouse using openGL, and normally the mouse hides just fine, but when I drag files onto the program's window, the windows cursor shows the drag-and-drop square and will not hide. ShowCursor(False) and SetCursor(None) (in python) are inconsistent for
