问题 In an earlier post Passing pointer from managed C++/CLI to ActiveX C++ component I've asked about the correct means to pass an array (whether managed or unmanaged array) to an activeX component created in native C++. The activeX method has the following signature: short Component::CopyToBuffer(short FAR* ptr) {} when the activeX is imported to be used in C++/CLI the method signature is displayed as short Component::CopyToBuffer(short% ptr) {} when imported in C# it is displayed as short

问题 I've added WindowsMediaPlayer ActiveX to my WPF/MVVM application. Now I need the control to react to changes happening in the viewmodel (most importantly updating URL when the current selection in my collection changes). Based on Walkthrough: Hosting an ActiveX Control in WPF I have the following in my Loaded event: // Create the interop host control. System.Windows.Forms.Integration.WindowsFormsHost host = new System.Windows.Forms.Integration.WindowsFormsHost(); // Create the ActiveX control

问题 I am looking for a way to invoke the print/save/email functions from the Adobe Reader plugin in the browser.

And the plugin has the save/email/print buttons on it. Also, there are four similar html buttons on top of it. When clicked on the html buttons on top, I would like to invoke the button within the

问题 I'm working on a browser plugin using ActiveX/COM and I'm trying to pass a Javascript function to a method call so that it can be used as a callback. I've been able to get the function assigned to a property on the ActiveX object, but since the method is async all calls to the method must share the same callback. I've seen this existing SO question but I'm not sure if this is the exact same problem since I'm not dealing directly with function pointers. Example of what we have now : var obj =

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'm having problems with my .net controls not getting cleaned up properly when wrapped for activeX use. The default behavior leaves the SDK's test container app (TstCon32.exe) running as a GUIless process when I try and close it. The workaround I initially found via google was to override WndProc and call Environment.Exit(0) manually. This did get TstCon32.exe to shut down completely; however it's breaking the application where i need to have the control hosted. The App is MDI and WM_DESTROY

问题 How do you expose an WinForms UserControl written in C# as an ActiveX control? My goal is to then use this UserControl from other languages such as VB6 or Delphi. 回答1: The solution is to use the Interop Toolkit, see http://msdn.microsoft.com/en-us/vbasic/bb419144 and http://www.codeproject.com/KB/vb-interop/VB6InteropToolkit2.aspx. 回答2: You will need to create a Runnable Callable Wrapper or COM Callable Wrapper depending on your direction. 来源： https://stackoverflow.com/questions/7409433
