问题 I have several interfaces, e.g. IA, IB, IC, and so on, that share common properties, e.g. Site. I would like to know how to reuse code for these interfaces (please save me the answer on COM aggregation). Current implementation is as follows: class CA // ATL specific... { STDMETHODIMP get_Site(...) {...} STDMETHODIMP put_Site(...) {...} } class BA // ATL specific... { STDMETHODIMP get_Site(...) {...} STDMETHODIMP put_Site(...) {...} } class CC // ATL specific... { STDMETHODIMP get_Site(...) {.

问题 I have an ASP.NET project using a COM dll. When I load the site, I login without a problem and I can browse the site fine as long as I don't go to a page which uses the COM library. When I go to a page which uses the COM library to get data from a database, the page loads fine. The problem comes when I navigate away form this page. For some reason I am sent back to the login page as if the initial session was dropped. If I take away the component on the page which displays the data which the

问题 I've had to move a classic ASP application from windows server 2008 to Windows Server 2012R2 and the app uses a com object called (aspmail 4.0) from a company called ServerObjects - which is no longer in business (at least there's no way to contact them). Anyway, I've registered the DLL ( C:\Windows\SysWOW64\regsvr32.exe d:\components\aspmail4\smtpsvg.dll ), that works as I checked the registry (it's 100% installed no issues nor errors). I've verified the DLL is correct and the registry is

问题 I have a window based on the CAxWindow. In this window I create WebBrowser control. When the DISPID_DOCUMENTCOMPLETE happens I do: void __stdcall document_complete( LPDISPATCH pBrowser, VARIANT* ) { CComQIPtr< IWebBrowser2 > wb( pBrowser ); CComPtr< IDispatch > doc; if( SUCCEEDED( wb->get_Document( &doc ) ) ) { _docs.push_back( doc ); } ... } When the page is loaded I call for each document in _docs the script (IActiveScript and IActiveScriptSite): function main( doc ) { try { return doc.URL;

问题 I have a pointer to a COM object (in C++). Is there a way to get the current reference count of the object which the pointer is pointing to? 回答1: Call IUnknown::AddRef and then immediately IUnknown::Release . The value returned by the latter is current count of outstanding references. Note that the value does not have to be accurate, it is informational only. 来源： https://stackoverflow.com/questions/30703812/how-to-get-the-current-reference-count-of-an-object

问题 I am having a hard time trying to figure out how to address leaking memory. I think this might be an issue with pywin32 but I am not completely sure. My code to do reading/writing individual items seems to work just fine, but when using group functions it slowly leaks memory. I suspect this is from the 1-based array that must be passed in the server_handles. Does anyone know of a work around? def read_group(self, group, mode=OPC_SYNC, source=OPC_DS_CACHE): """ Read a group returning a list of

问题 I have a set of libraries written in Delphi.NET (.NET 1.1) which I want to use in my Win32 (Delphi) application. For performance related issues, I've decided to follow the COM route. Sometimes, after rebuilding the DLL, when I try to instantiate the objects exposed through COM, the Win32 application hangs at the CreateComObject call. How can I solve this problem? To expose the Delphi.NET libraries through COM, I add the following attributes above each class deceleration: [Comvisible(true)]

问题 Is there a good way to see if two documents are the same using the word interop? I have tried using something like: Word.Document tempDoc = app.CompareDocuments(document1, document2); My issue is that tempDoc is not null if they are the same, so I'm not sure how to use this result to determine whether the documents are the same. Thanks in advance! 回答1: The document it returns is a document with track changes turned on. So all you have to do is see if there ARE any changes. So: Document

问题 I have a CSV file which contains dates formatted as m/dd/yyyy as follows 1/06/2013,15,1,1/06/2013 0:15,1,6.44 When I open the file in Excel, the dates are correctly converted - 1/06/2013 has numeric value 41,426.00 and the MONTH() function returns 6. When I use Microsoft.Office.Interop.Excel to open the same file using either the Open() or OpenText() method the date gets converted to 41,280.00 (6/01/2013). Can you open a CSV file using Microsoft.Office.Interop.Excel so that it opens the same
