Importing Quicktime 7 into BDS2006 - I can't get it to
compile

Had to choose between multimedia and activex.using - I figured I'd start 
here.

I wanted to try the newest Quicktime 7.2 control in Delphi Win32 in BDS2006. 
Had some issues trying to import the ActiveX control/type library 
information, since the Import Component stuff changed. Found an example, and 
tried to match it with the instructions in John Cromie's book on the new 
Quicktime stuff.

So I've got a control and it looks OK, but when I try to compile a simple 
test application, I'm getting the following error messages:

[Pascal Error] QTOLibrary_TLB.pas(3959): E2010 Incompatible types: 'QTPOINT' 
and 'Variant'
[Pascal Error] QTOLibrary_TLB.pas(3970): E2160 Type not allowed in OLE 
Automation call
[Pascal Error] QTOLibrary_TLB.pas(4280): E2010 Incompatible types: 'QTRECT' 
and 'Variant'
[Pascal Error] QTOLibrary_TLB.pas(4291): E2160 Type not allowed in OLE 
Automation call
[Pascal Fatal Error] Unit1.pas(7): F2063 Could not compile used unit 
'QTOLibrary_TLB.pas'

A bit of digging in Google found a set of messages initiated by myself in 
December 2005, dealing with the first QT7 stuff, but back at Delphi 7. I got 
that working, and it's not the same problem. I've got the code to handle the 
FPU control word in the program now.

Anyone done this and can point out how I should really import the Quicktime 
stuff into BDS2006?

Thanks.

To be honest, when using the older Quicktime 6 ActiveX control, I have the 
SkyLight library from skylark.ie as the interface. It works really well for 
my application.

The guy behind that, John Cromie, is the guy who then built the new 
Quicktime 7 control, and wrote the book "Quicktime for .NET and COM 
Developers" that describes the new implementation.

I'm trying to get back into a place where I can play with the new control, 
but the Quicktime 7.2 release seems to have issues on my import to BDS2006 
(and Delphi 7, it turns out. I tried that last night too). 

I've never had much luck with Quicktime ActiveX components even when 
disabling the floating-point exceptions. I've only ever been able to set 
the URL ie

QTControl1.ControlInterface.URL := OpenDialog1.FileName;

but with everything else such as

QTControl1.ControlInterface.MovieControllerVisible := False;
or
QTControl1.ControlInterface.Movie.Play(1);

cause access violations. How do you use the ActiveX control when you had 
it working?

I currently use the Quicktime Movie component found here: 
http://www.delphipages.com/result.cfm?ID=2416 works a treat for me with 
Quicktime 7, but still need to call Set8087CW($133f) and it doesn't 
provide all the functionality the the ActiveX control can - if working.

Cheers, harrie.

Looks like this was strictly a user problem  - I think I generated too many 
wrappers for the QTOLibrary when I tried to import it. I redid the import 
this morning and got things working.
