upgrade vb6 project using msdxm.ocx to wmp.dll

We have a legacy vb6 application that uses an ancient windows media player component, msdxm.ocx, to embed ultrasound (pregnancy) video's in the medical record.

This doesn't work any m开发者_如何学运维ore on Windows 7: it has a newer version of msdxm.ocx which cannot be referenced from vb6.

The newer version of the embeddable player is wmp.dll, so we are planning to upgrade the application to the newer version for Windows 7.

Before we have to find it all out the hard way by ourselves: does someone have experience with this upgrade from msdxm.ocx to wpm.dll? Is there a list of things to consider when upgrading? Or a table to convert constants and events from the first to the second?

I haven't seen anything listing their object models side-by-side or offering any "conversion."

The msdxm.ocx was really a scriptable IE object and should not have been used in VB6 programs. Lots of people did though. Windows 7 still has this OCX but starting with Vista (or perhaps IE7?) its interfaces changed in a way that seems to prevent use in VB6 programs.

You might want to try running a tool like ActiveX Documenter aginst working versions of both libraries to assist your efforts though. The RTF output documents might be a starting point for writing your own conversion guide.

msdxm.ocx should still work if you put the OCX file in C:\Windows\SysWOW64 and register it.

I've tried on my Win7 and it works on my music player legacy app.

Don't know about Windows 8 though, but it might still be the same, MS might changed folder again then.
