How to make COM ActiveX object work in IE 64 bit?

阅读更多关于 How to make COM ActiveX object work in IE 64 bit?

问题 I have a COM object embeded in ASP.NET page using <object classid="clsid:XXX..."> . It works in IE 32 bit, but does not work in IE 64 bit - can't access its functions. There are no error messages, no event logs where I can get some information. The dll is in C#, includes COM visible class, compiled for Any CPU (though I also tried x86), and registered during client installation by executing regasm. This creates registry keys, well everything works fine except for IE 64. I searched internet

问题 In delphi, creating ActiveX controls was something that was once more popular than it is now. However it remains possible to create ActiveX controls with Delphi. This question assumes Delphi 2007, but it should be the same no matter what Delphi version you use. There are some strange errors in Delphi when you create ActiveX controls. IN my case, I can now no longer import a certain class that I am trying to import and wrap, and Delphi won't tell me why any more, just that it could not load

Adding #include <boost/thread/mutex.hpp> breaks my ActiveX control?

阅读更多关于 Adding #include breaks my ActiveX control?

问题 Is there a known problem with the boost::mutex header when used inside an ActiveX control? (Boost version v1.39) If I create an MFC ActiveX Control project in Visual Studio 2008 called "DefaultOCXControl" then I can build it, the control registers itself as part of the build, and can be inserted into the ActiveX Test Container as you would expect. All good. If I then just add this line: #include <boost/thread/mutex.hpp> at the top of my DefaultOCXControlCtrl.h file and rebuild: the

问题 I have a JScript script that runs using cscript.exe . It creates a shortcut on the desktop (and in the start menu) that runs cscript.exe with parameters to run another JScript script. It looks, in relevant part, like this: function create_shortcut_at(folder, target_script_folder) { var shell = new ActiveXObject("WScript.Shell"); var shortcut = shell.CreateShortcut(folder + "\\Run The Script.lnk"); shortcut.TargetPath = "cscript"; shortcut.Arguments = "\""+target_script_folder+"\\script.js\"

问题 I'm trying to update the caption of an ActiveX control button on an Excel spreadsheet to note that the code associated with the click event is working. The code pulls data from an azure database so pressing the button triggers anywhere from a 5-10 sec delay. My original code had a single sub that essentially looked like this: Sub GetInfofromDB() btnUpdate.Caption = "Updating...." <<code to get data from azure db>> btnUpdate.Caption = "Update List" 'reverts button to standard text End Sub
