问题 I am trying to use the "Microsoft Terminal Services Active Client" in Delphi. I see that I can create the COM *.tlb file either via " Import ActiveX control " or " Import Type Library ". They both seem to give the same *.tlb source file. Is there a difference between the two approaches. (Long time Delphi user, but new to COM). 回答1: Delphi Help System says: "The Import Type Library dialog box displays the type libraries registered on your system so you can add them to your projects. If the

问题 I'm using ASP.NET on the server side and JavaScript on the client side. I'm trying to develop some pages that will help the user troubleshoot and I was wondering if there was a way to programmatically determine the following: if ActiveX has been disabled in Internet Explorer if an ActiveX control has been installed if an ActiveX control has been installed but disabled For cases 2 and 3, I know that in order to detect that an ActiveX control is installed, you would use the following check in

问题 I'd like to create an ActiveX button in a sheet and assign a code to it (i.e. tell it to what sub to run and that sub already exists). I can create the button: (recorded) ActiveSheet.OLEObjects.Add(ClassType:="Forms.CommandButton.1", Link:=False _ , DisplayAsIcon:=False, Left:=41395.5882352941, Top:=234.705882352941, _ Width:=119.117647058824, Height:=39.7058823529412).Select But I'd like to change the caption and assign a sub to it so when someone clicks the newly created activex button it

问题 IE9 users can disable an add-on, such as a browser helper object, by clicking on the cog button and selecting "Manage Add-Ons". I need to detect if a given add-on has been disabled in such way, using JavaScript. I can't seem to find a way for my error handler ( <object ... onerror="myhandler(event)" ) to detect that the BHO has been disabled. errorEvent.type is simply "error" . Is there any way? I need to detect this scenario because just having the webpage try to install the BHO again yields

问题 I have two figures in MATLAB with the handles hFig1 and hFig2 . I would like to print them to specific cells in Excel (cells E3 and I3) and reshape them to each be [2in x 3in]. I have tried using the .AddPictures object handler and using print -dmeta , but I can't find a way to achieve all three of my objectives. I am also writing data to excel at the same time and because there is a lot of data lines being sent, I was hoping to have a method that didn't require continually invoking excel

问题 I need to build a managed DLL, targeted for x64, and expose it via x64 COM. I need a walk through, good article, etc... Interop is fairly straightforward, but when you talk about x64 on both sides, I can't find anything. 回答1: Take a look at this discussion. And this. 来源： https://stackoverflow.com/questions/95628/how-to-build-a-64-bit-net-dll-with-64-bit-com-interop

问题 I have developed an ActiveX Control in C#.NET. I created a class library with a default interface. Given GUID , ProgId and made it COM visible , interoperable. Registered. Created a cab file , then embedded it in HTML page using object tag by specifying it's classid and codebase. Loaded it using JavaScript Method. It is working. But problem is that it runs as a separate window other than Internet explorer. I want it to be loaded inside IE that is as a part of IE window. How to do it? --

问题 [ToDo] (1) As indicated from NGLN's helpful answer, using simpler keywords such as "Delphi ActiveX control" to search.

问题 I've written an ActiveX control in C++ that throws (C++) exceptions out when error conditions occur within the control. The Javascript code that invokes the object representing an instance of the control is surrounded by a try - catch block: try { var controlInstance = window.controlInstance; ... perform operations on controlInstance ... } catch (e) { alert("something bad happened"); } Now, when I run this code under IE8 (or 7 or 6) with a Visual Studio (2008) debugger attached to it,
