I have this very simple program: from win32com import client ie=client.Dispatch("InternetExplorer.Application") This used to work (I think I broke something when I re-used 'makepy.py' to try and add in constants for IE). It still works on another machine where I haven't been so slap-dash with 'makepy.py'. Here's what I get in an int...
Environment: Windows XP machine Both Excel 2007 and Excel 2003 installed (in that order, not chronologically). C# 3.5 Problem: When I use the PIAs to do some Office automation, I use the following line of code: var excel = new ApplicationClass(); The PIA's version specifically refers to it as Excel 12.

Hello I have a .NET DLL that writes to the Trace. But seems that when I call my DLL from a VB6 EXE the trace is not working. I have created an myApp.config file in the EXE folder with the trace configuration, but this does not solves the issue. I've also tried creating the Trace objects in code,but doesn't work: Dim _traceSrc as Trace...

COMClass a = IComClass as ComClass; a.SomeEvent += new SomeEvent_EventHandler(MethodNameHere); Line two throws an exception of type COMException with the following information: System.Runtime.InteropServices.C...
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?" Equal...

And you can run the setup over and over again.. Is there any danger in doing so?? What would happen if i deploy à new setup with à new version of the dll.. Is there any danger in n...
I have a native C++ DLL using DirectX, that I want to be able to use through C# to be able to create content creation tools. Adding COM would require quite an effort it seems. Can P/Invoke be used to maintain classes using polymorphism, or would it require me to wrap most of the code to facilitate use of P/Invoke? It there a better sol...
I have HTML document to print from embedded COM IWebBrowser object. And although in IE itself it printed with correct page breaks (by page-break-inside in CSS). In my application it make it wrong. I'm already dig it much. Can you suggest something? ...
I'm using an extensive existing COM API (could be Outlook, but it's not) in .NET (C#). I've done this by adding a "COM Reference" in Visual Studio so all the "magic" is done behind the scenes (i.e., I don't have to manually run tlbimp). While the COM API can now be "easily" used from .NET, it is not very .NET friendly. For example, th...
I'm very new to COM and Windows programming/scripting in general. What I was trying to do is scripting Windows Live Writer; according to the documentation before I can call $o = New-Object -c WindowsLiveWriter.Application I need to load the TLB first, so I should call the add-type command, unfortunately it fails: PS C:\Users\NoWher...
I have some COM component which I call from some c# dll. I also have a winforms app that uses that .dll. When I close the app I get this exception: COM object that has been separated from its underlying RCW cannot be used. The stack trace shows this exception comes from a destructor in the .dll. I implemented this destructor ...
I'm following this article to registering SENS events via COM, but I think I'm missing something. I'm calling the SubscribeToEvents method the article says to write, like this: EventSystemRegistrar.SubscribeToEvents("ManagedSENS EventSubscriber", "ManagedSENS.SensLogonInterop", subscriptionViewerID, this, typeof(SensLogon)); which lea...

OK, I suspect I'm going to have difficulty even putting this in words since my understanding of COM and apartments isn't really up to the job ;-) I have a COM in-process server/component (C++) that wraps some legacy code. Due to the limitations of this legacy code I need to ensure that the methods of the COM component are: only called...
I am trying to work with the Windows clipboard and Office Interop in an ASP.NET web application. Everything works well on my local machine running XP (i have created a Windows application first which ran perfectly well on local machine). Then I have executed it on a server running Windows Server 2003 and it worked there as well. Then I...
Hi, I maintain a program which can be automated via COM. Generally customers use VBS to do their scripting, but we have a couple of customers who use Matlab's ActiveX support and are having trouble calling COM object methods with a NULL parameter. They've asked how they do this in Matlab - and I've been scouring Mathworks' COM/ActiveX...
I'm using CDO message class to send mails. How to set the content type to UTF-8. Currently I'm getting junk characters in the mail body. CComPtr<IMessage> piMsg; ...
I want to have a small app to add and remove user defined context menu entries from the registry. To make this somehow I need to get the CLSID of an arbitrary DLL so I can back up previous entries if they exist and then write new ones. Although regsrv32 somehow manages to create this magical number, I didn't find any answer with google. ...
I've been an admirer of Juval Lowy's teaching and guidance in .NET development for a number of years. He's also written one of my favorite books: Programming .NET Components. However on a recent DotNet Rocks podcast (Jan 2010) in discussing WCF/COM and .NET, he made some comments that greatly surprised me: Juval Löwy: ..... in .N...
The respected open source .NET wrapper implementation (SharpBITS) of Windows BITS services fails identifying the underlying BITS version under Win7 x64. Here is the source code that fails. NativeMethods are native Win32 calls wrapped by .NET methods and decorated via DllImport attribute. private static BitsVersion GetBitsVersion() ...
