问题 I have a complicated program for working with documents. Client requirement: it should be conditionally integrated in Windows Explorer context menu during install, i.e. then user check the corresponding option. So, in my Inno Setup script [Tasks] i've created a separate task named IntegrateToExporer . And in the [Files] section - two COM DLL files (x86/x86-64 version) with regserver flag. My question is: how to make regserver flag conditional? it must be applied only if user select

问题 [continued from Is there a way to tell whether two COM interface references point at the same instance?] I've got references to Inspector objects from two different sources and need to be able to tell which item from one source corresponds to which item from the other source. However, none of the approaches I have been able to come up with so far worked (reliably): I couldn't simply compare the IUnknown interfaces as it seems that the Inspectors.Item() method is returning a reference to a

问题 Our COM component interface has the next method: HRESULT CreatePluginWindow([in] HWND hParent, [in] RECT* prcView); We are going to use it in .NET application but interop for this interface is looking like this: void CreatePluginWindow(ref interop.alfrontx._RemotableHandle hParent, ref interop.alfrontx.tagRECT prcView) According my investigation there is no way to use this method without unsafe code. I'd not like to change COM interface in order to use other than HWND type for hParent,

问题 I want to add support for searching for local Outlook contacts to my ATL/WTL app. Does anyone know of the Outlook COM interface (Office 2003 or greater) allows you to search for contacts? I already have LDAP lookup support but users want to be able to search their private contacts as well. Any information would be welcome. 回答1: To get access to the contacts you first have to get a Namespace object using the Application's GetNamespace function, passing "MAPI" as the namespace name. Then you

问题 Microsoft provides a method as part of WinHTTP which allows a user to determine which Proxy ought to be used for any given URL. It's called WinHttpGetProxyForUrl. Unfortunately I'm programming in python so I cannot directly access this function - I can use Win32COM to call any Microsoft service with a COM interface. So is there any way to get access to this function from Python? As an additional problem I'm not able to add anything other than Python to the project. That means however
