ASP/Custom Activex Error

I have set up a website and am testing ASPs. I have created
a very simple ActiveX component with two interfaces:

AboutBox() - displays About details
calcpi() - returns 3.14159

Here is my configuration (All the most up to date versions
except for Visual C++):

Windows XP (Home Edition).
Visual C++ 6.0
Apache Webserver
SUN ASPONE
Internet Explorer

When I use ATL COM Appwizard to create my ActiveX
component (DLL really), I can get the following
to work quite easily:

<%
Set x =Server.CreateO bject("AC.AcCtr l.1")

x.calcpi()
%>

However, when I use MFC ActiveX Control Wizzard to create
my ActiveX (.ocx really) component, the above does not
work. Well, the instantion of the x object appears to
work but I obtain the following error when I try to
invoke x.calcpi():

error '8000ffff'

/t.asp, line 4

Can anyone tell me what they think is happening here?

Possible problems: Internet Explorer ?
ActiveX Wizzard ?
XP Home Edition ?
SUN ASPONE ? (least likely)
Thanks,
John Gabriel

to host an active/x control in IE you must implement the IDispatch interface
for all your methods you wish to call. (this is somethimes referd to as a
"dual" interface).

I have a VB.NET solution with some projects. One project is the main application, the other projects are custom controls library. In the main application I have an ActiveX charting tool. Sometimes when I open o rebuild my solution I see that the activeX controls or my .NET custom control are not anymore in the form where I placed them. They are still the region code: #Region " Windows Form Designer generated code "

I have the SystemMonitor ActiveX control on a form and I try to register a custom performance counter.

My department is responsible for creating custom internal applications for many of our departments.

So far, I've experienced a number of items that caused us a few stalls, but mostly was able to resolve them after some thinking and...

I've been provided with a custom ActiveX DLL (written in C++) that reads a certiifcate to generate a signature for a passed XML string, and I'm having trouble instantiating it.

The DLL comes with a testtool (written in Visual Basic) which instantiates the object like this: Dim loCertCryptCOM As New CCOMCRYPTLib.CCrypt As you can...

Hi All, I'm trying to display .NET Custom Control (created using Inherited Control) on an ASPX page, but no luck. I already registered the Control to Global Assembly Cache through .NET Framework 1.1 Configuration. I have also put a reference to the control on my ASP .NET project. The view that I get is only a disabled text area. Below is the code that I'm using:

Hi, I've created a C# custom control that references some ActiveX controls. I need to host this control on a form that also hosts the same ActiveX controls. So I add the custom control and the individual ActiveX's to the toolbox & when I try to host the user control on the form using the toolbox, the VS.NET interop kicks in generates Ax*** wrappers for these.

Does anyone know if there is a way to set a custom mouse cursor for an ActiveX control in .Net? I am adding some mouse functionality to an existing ActiveX control, and would like to change the cursor shape according to the current state. It's a Windows Forms app, with an ActiveX control wrapped in the (automatically generated) class (derived from AxHost). Although AxHost is derived from Windows.Forms.Control, the public Cursor property does...
