Re: Yet another post about QuickTime and .NET

QuickTime 7 includes a new QuickTime COM/ActiveX control targeted at COM and .NET developers using Visual Basic .NET, C# and of course C++.

Public Preview 3 may be downloaded from:
http://www.apple.com/quicktime/download/preview/


To add the QuickTime COM control to your VS.NET Toolbox:

* Right-click anywhere in the Toolbox and choose Add/Remove ItemsÂ… to bring up the Customize Toolbox dialog.

* Choose the COM Components tab

* Check "Apple QuickTime Control 2.0" and click OK.


Once you have added an instance of the control to your Windows Forms form, you can load a movie by setting the URL property of the QuickTime control.

In VB.NET:

AxQTControl1.URL = "">
Once a movie is loaded, the Movie property of the control provides access to the QTMovie COM object which wraps the movie.

e.g.

AxQTControl1.Movie.Play()

Dim trackLength As Long = AxQTControl1.Movie.Tracks(1).Duration


You can use the Object Browser to explore the object model provided in the QTOControlLib and QTOLibrary namespaces: documentation is not yet available.


Hope this helps,

I'm trying to integrate QuickTime VR movies into a Visual C++ .NET
Forms-based application.  I am new to C++, native Windows development in
general, and the QuickTime API.  Its all rather intimidating!  Okay, so
I do have some Java experience, and a lot of QTVR experience using
Director, so it isn't quite as bleak as all that :)

I've been doing my homework, searching through the list archives and
reading everything I could about interfacing between QuickTime and .NET.
I've looked at some unmanaged sample code (SimplePlayerSDI).  I
understand that there are basically three approaches: 1)ActiveX control,
2)PInvoke,  and 3)IJW.  I am targeting QuickTime 6.5, and purchasing a
third party ActiveX control is not an option, so #1 is out.

My question is really the same as a question someone asked previously,
but I didn't see any response.  I understand how to call QuickTime
routines from .NET, but what do I do with QuickTime objects?  How can I
obtain and use a Movie or MovieController object in .NET?  Basically,
how do I actually get these and add them so they will display on my
Form?

I don't mean to seem like I'm too lazy to do my own work, but is there a
chance someone could provide me with some sample code which displays a
movie in a .NET Form using either PInvoke or IJW?  Just the very basics,
and I'll work out the rest myself.
