Exploring ActiveX Control (.ocx) from available binaries

Question

Hi,

I have a device controlled by a controller with a software interface. I do not have any documentation regarding SDK available but a manual for software.

This software has .dll files and .ocx files available in it's Binaries folder.

I want to develop a custom application in C# to communicate with the controller using available .ocx and .dll files.

First of all I want to know if this task is achievable. Secondly, if it is achievable then how?

Can .ocx files be of any help to me? I do not know what to start with.

Kindly, help me in this regards.

Cheers,

Proof.

It depends if the a typelib is available for the OCX. It may be included as a resource in the binary or somewhere else. The quickest way to check that is to add OCX reference in C#. "Add Reference->Browse". Visual Studio will try to create a wrapper of the ocx. If it succeeds you may start controlling the ocx from C# code. You don't have any documentation so that you should guess the behavior from property and method names.

I tried doing so but it gives an error "A reference to abc.ocx could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component". I rather added the component to the tool box and dragged and dropped it onto a form.

I cannot figure out any resolution. Is this OCX part of a large application so that it depends on other components? Can you send me the OCX file?

Hi Babak,

How shall I send you the file?
