change midi input channel

Anonymous — Fri, 20 Jan 2006 17:39:16 -0000

I am fairly green at VB but I still can find no
method to have the midi input respond to any channel
other than 1. Is there a method or property to
accomplish this?

Thanks,
Eric

Change DeviceId in controls without closing & loosing data ?

jtbalogh — Sun, 30 Jan 2005 06:54:26 -0000

RE: Change DeviceId in controls without closing &
loosing data ?

Goal: Change DeviceId in controls in order to,
- avoid closing and opening object
- preserve data that was already prepared
- preserve most data at least, if not all

Right now I am working on the ReOpen() method to
accomplish this while maintaining backward compatibility.
Sorry I did not get to solve this obvious feature earlier.
Sure was a lame idea to close and open object just to
change a device Id. Thanks microsoft !

Select no DeviceId in controls but still allow to open ?

RE: Select no DeviceId in controls but still allow to
open ?

Goal: Select no DeviceId in controls in order to,
- allow to open and prepare data
- another way to turn off all midi input or output
- change DeviceId later when ready to use
- open and not take exclusive use of any ports yet

Right now I am working on the DeviceId property to
accomplish this while maintaining backward compatibility.
Sorry I did not get to solve this obvious feature earlier.
Sure was a hassle for VB program to determine if midi
input or output was disabled. Sure was a hassle to take
exclusive use of ports all the time when the program
does not not need it all the time.

input not working (closed)

Anonymous — Wed, 01 Sep 2004 16:45:33 -0000

I installed the ocx and the output works fine. I cannot
get the input to do anything. It has the correct deviceid
but just sits there. I am am positive of input. I use a
MOTU Fastlane USB-MIDI box to a Win2000 HP Laptop.
I can send the source code to someone if they have
time to look at it.
Also, is there any more documentation other the the
small help file examples? There seems to be a lot of
difference between the Mabry version and the one that
was released here.

Simplify MidiTest demo code ?

jtbalogh — Mon, 16 Aug 2004 03:09:45 -0000

Simplify MidiTest demo code is a good suggestion.
Investigating easier ways to use the multithreaded
scrollbar, multithreaded textbox, status boxes, progress
bars, etc. so that the code does not look crazy. Also
more classes and fewer public variables could help group
features closer together. In most cases, it is more
practical to strive for ease of use and sacrifice speed.
Demos look worse when code is not modular.

Unfortunately usercontrols in VB have had lots of
problems and could not always help encapsulate
features reliably. Adding separate active-x projects to
handle features affected all windows programs, access
was even slower, and was a hassle to maintain multiple
projects just for one demo.

Just a thought.

Control has no threading model? (closed)

jtbalogh — Mon, 02 Aug 2004 17:15:32 -0000

Control has no threading model? The OLEVIEW
application in the Visual Studio 2000 tools reports the
controls have the threading model set to none. Why not
equal to apartment or free?

None represents single-threaded applications.
Apartment represents limited multithreaded applications.
Free represents full multithreaded applications.

Solution:

Not an issue. The controls are already compiled to use
runtime libraries with a multithreaded DLL which is safe
for multithreaded apartment or free applications, and
backward compatible with single-threaded applications.
Visual basic applications, for example, normally use
apartment. Visual C+ applications normally use free. DOS
applications normally use none.

In general though, a multithreaded apartment
architecture is preferred. It is safer to handle the public
storage and functions in the controls. Also each
instance of a control is protected from every other
instance.
