I'm trying to use a feature of the Microsoft WinHttp library that has been exposed by the developers of Win32com. Unfortunately most of the library does not seem to be documented and there are no example of the correct way to use the win32inet features via the win32com library. This is what I have so far: import win32inet hinternet = win32inet.InternetOpen("foo 1.0", 0, "", "", 0) # Does not work!!! proxy = win32inet.WinHttpGetProxyForUrl( hinternet, u"http://www.foo.com", 0 ) As you can see, all I am trying to do is use the win32inet feature to find out which proxy is the appropriate one to

The following method is a DCOM server method. The COM client and server is running in different WinXP machines. The COM client calls RegisterClient method to register callback interface. The problem is QueryInterface method fails with error code E_ACCESSDENIED . What could be the reason for the issue? STDMETHODIMP CGEMExtension::RegisterClient(IUnknown** ppGEMExtensionEvents, int* nClientId, int* nResult) { HRESULT hRes = (*ppGEMExtensionEvents)->QueryInterface(IID_IGEMExtension,(void**)&pUnknown); return hRes; } When you get an E_ACCESSDENIED, it means you have a permissions problem (don't

Let's say I'm developing an application that installs COM component and installer registers them. This works great. Now the software is required to run from a memory stick. How can I register my libraries runtime and make sure, that the registry is cleaned up after running the application? Are you always running on XP or later? Don't bother. Use "registration free COM". Essentially what you do is create a manifest file for the COM component so the Windows loader know what its registration is without having to put that in the registry. A walkthrough of what to do is in this article on MSDN:

Related question [stackoverflow] here . I'm trying to do the above, but I want to take the process one step further. I want to open an arbitrary file using the default editor for the file type. From that point, I want to allow my user to interact with the file as they would normally, or continue to work in my application. The extension is what happens after the user finishes editing. Is there a way I can capture a close (and ideally save) event from the external application and use that as a trigger to do something else? For my purposes, tracking the closing of the external application would

I am trying to build a byte array in PHP using Variants . However, I can't seem to make it work. Here's a sample code: $ie = new COM("InternetExplorer.Application"); $ie->Visible = true; $ie->Height = 500 ; $ie->Width = 700 ; $post = array (ord('p'),ord('='),ord('1')) ; $v = new VARIANT($post, VT_ARRAY|VT_UI1); $ie->Navigate2("http://host/web/echo_request.php",0,'',$v) ; The code produces an error: Fatal error: Uncaught exception 'com_exception' with message 'Variant type conversion failed: Type mismatch.type conversion failed: Type mismatch. I have tried with all sorts of combinations for the

I have a C# project, where I would like to access MS outlook, if it is installed on a client´s machine. The "access outlook" part has been done by referencing the outlook COM object, and going from there. My problem is now the "if it is installed" part. At the moment, my project doesn´t compile on machines without outlook installed, so I assume that I will have to not reference the outlook component, and instead load and use it dynamically, after detecting that outlook is present, but I haven´t found a way to do this. Am I correct, and does anybody have any hints on how to do this? Thanks.

We have developed a s/w architecture consisting of set of objects developed in C#. They make extensive use of events to notify the client of changes in status, etc. The intention originally was to allow legacy code to use these managed objects through COM interop services. That was easy to write in the design specification but, I'm seeing that actually implementing it is more problematic. I've searched for many hours looking for a good sample of event handling using this method. Before we march down that path, I want to make sure that COM interop is the best way to allow legacy code to call
