activex

I have created an ActiveX dll using VB6 and packaged it using the Package & Deployment Wizard which has resulted in a cab file and a demo HTML page. This ActiveX dll contains a simgle method that returns a string and accepts no arguments. The trouble I'm having is that when I call the method I always get a "Object does not support this property or method" error. But it does support the method I'm calling. What I'm trying to achieve is for users to go to a web page that has some java or vb script in it that calls method in my ActiveX and gets the string value returned. The DLL is intended to be

I have created a Windows Forms UserControl that can be exposed as an ActiveX Control. Now I am trying to do the same with a WPF UserControl. The Winforms UserControl base class I noticed is ComVisible however the WPF UserControl class is not. Am I trying to do the impossible? Is the only way to achieve this to write a WPF control and then embed it in a Winforms UserControl using ElementHost and then expose that Winforms UserControl as an ActiveX control? Yes, I think ElementHost is the approach you will need to use if there is a chance of this working. This is because WPF controls are

We have a WinForms application written in C# that uses the AxAcroPDFLib.AxAcroPDF component to load and print a PDF file. Has been working without any problems in Windows XP. I have moved my development environment to Vista 64 bit and now the application will not run (on Vista 64) unless I remove the AxAcroPDF component. I get the following error when the application runs: "System.Runtime.InteropServices.COMException: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))." I have been advised on the Adobe Forums that the reason for the error is that they do not have a

I am doing some maintenance on a VB6 Windows application. I have a .Net custom control component that I would like to use on a VB6 form. Is this possible? I know how to access non-visual .Net components from VB6 by generating a COM type library for the .Net DLL, but can a .Net custom control be used like a .OCX from VB6? If so, how is the control instantiated in VB6, added to the form, etc. Thanks in advance for any replies. The Interop Forms toolkit will give you what you need: http://msdn.microsoft.com/en-us/vbasic/bb419144.aspx It lets you create UserControls in VB.net which you can then

I am trying to figure out a bizarre situation. I have a workbook with many sheets. On one sheet, I have one ActiveX listbox (CTOverview.Listbox1). On a second sheet, I have a total of three listboxes (CTSelected.Listbox1 thru Listbox3). I am using a query to populate Listbox1 on both sheets with the same data. The code for this is below: strSQL = "Select Distinct [Region] From [UniqueCTList$] Order by [Region]" closeRS OpenDB ' initialize listboxes CTSelect.ListBox1.Clear CTSelect.ListBox2.Clear CTSelect.ListBox3.Clear CTOverview.ListBox1.Clear ' initialize with entire division value CTSelect

Few similarities I know.. Both cannot execute by themself. It needs some program to instantiate it. COM DLL & ActiveX controls are platform independant. (is it so...?) Both requires to support the interface IUnknown and exposes three methods QueryInterface , AddRef , and Release . It also requires to be registered before using and un-registered after done with it. But how are they different? Can someone please list it down? Also my understanding is ActiveX controls are OLE custom controls (OCX). I have heard of terms like ActiveX DLLs. Is it another form of ActiveX control or something
