问题 I've implemented a windows deskband (using the windows SDK sample) and need a way to communicate (one call to start IPC with another application, IPC is already working) with it. My COM experience is very limited but extrapolating from what I've seen, I think it should be possible to create a new COM interface, implement it in the deskband object (which I have access to via IBandSite), call QueryInterface() for my own interface on it and then use it to call directly into the deskband. I've

问题 I'm trying to create a Word email message that will be used as the body for an Outlook message. I've been looking at sample code from Microsoft here but this code falls over when trying to create the new word document at the wordApp.Documents.Add line: Word.Application wordApp = new Word.Application(); object template = System.Reflection.Missing.Value; object newTemplate = System.Reflection.Missing.Value; object documentType = Word.WdNewDocumentType.wdNewEmailMessage; object visible = false;

问题 I'm trying to use this excellent example to implement dropping virtual files into Windows Explorer. However, I'm stymied by this error. Towards the bottom, inside void System.Runtime.InteropServices.ComTypes.IDataObject.GetData(ref System.Runtime.InteropServices.ComTypes.FORMATETC formatetc, out System.Runtime.InteropServices.ComTypes.STGMEDIUM medium) on the first call to ((System.Runtime.InteropServices.ComTypes.IDataObject)this).GetDataHere(ref formatetc, ref medium); I'm getting back a DV

问题 We are going to develop ASP pages for a WIN CE device. The web server running on the system is httpd. I have a few doubts on the scope of com objects Does WinCE(httpd) ASP support Session and App Scope? Does page scope alone is supported in ASP in Wince? What should I do to introduce session and app Scope? Where can I get more information on this? 回答1: Does WinCE(httpd) ASP support Session and App Scope? According to MSDN: Windows CE does not provide support for the Session or Application

问题 I have been having a prolonged encounter with the beast known as COM Interop... I am currently trying to generate a .tlb from a .idl file generated by the OLE/COM Object Viewer. However when trying to run Midl.exe to compile it I get an error: .\Sim.API.IDL(236) : error MIDL2025 : syntax error : expecting a type s pecification near "ImportFileStatus" My .idl file is more that 1000 lines long so I don't particularly want to post it here however, I believe the Part of interest is: typedef [uuid

问题 In the context of a Windows Universal Application, and using reflection, I'm trying to get the Add method from a ColumnDefinitionCollection (the built-in type) So I use this: type.GetRuntimeMethods().First(info => info.Name == "Add"); BUT it returns null! It also happens with the Contains method. Both of them are defined in ICollection<T> ( IList<T> derives from it). However, if I define my own class deriving from IList<T> , it works perfectly. Then, how do I get a MethodInfo for the Add

问题 We have a stripped down Connect class which instantiates the addin's core from an other assembly. Our architectural design is to keep the UI and business logic separated from the loading module (= Connect class), but the restrictions of a shared Addin make us troubles. what we did in Connect.cs: [GuidAttribute("XYZ"), ProgId("XYZ")] public class Connect : Object, IDTExtensibility2, ICustomQueryInterface { ... CustomQueryInterfaceResult ICustomQueryInterface.GetInterface(ref Guid iid, out

问题 I am able to call a COM interface method using SAFEARRAY(BSTR) as input. If I define instead a simple (containing only some BSTR-s fields) STRUCT to pass into the COM I get "[System.ArgumentException] = {"The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))" The call to my COM server is not made because as it seems the arguments from client does not match the expected arguments on server: E_INVALIDARG Here is my declaration in IDL: typedef enum UserEntityType { User

问题 I can't seem to find any information on how a "variant time" ( DATE, double, 8-byte variable ) is handled.... I have a variant time " A " which value is " 41716.892329 ". If I convert " A " using "VariantTimeToSystemTime" (or "COleDateTime") - I get " 2014-03-18 21:24:57 ". How is this variant time calculated? Is it capable of storing milliseconds? Is there any way to determine if variant time is an AM or PM time? I'm a bit confused regarding the AM/PM thing because the device that I'm
