Are there event handlers for graphic objects drawn with the CWIMAQViewer toolbar?

Hi,
I use the CWIMAQViewer in my VB.Net application to display images from a CCD camera. I want to use the toolbar that comes with the viewer to draw graphics (e.g. a circler) over the image. Is it possible to get the position and radius of the circle as I drag it and change its size? If not, what library should I use (I do have the NI Vision module) to achieve my goal? Thank you so much for your help.

Try creating the circle as a ROI. Then take a look at ROI properties. As an example, ROITop Property: CWIMAQ.ROITop

I have 3 computers...Window PC, PowerBook G3 (old) and MacBook Pro. I use firefox for all of them and have for quite some time. Is there a way for them all to use the same toolbar? Each of them have differnet bookmark/ settings etc.,

Open Media Encoder and add your Sequences:
File > Add Premiere Pro Sequence
Navigate to your Premiere Project and select it in the list.
You can then select multiple Sequences from the Project (Ctrl+Click)
and load them all at once into Media Encoder and apply
the same encoding preset to all Sequences at the same time.

Are there keyboard shortcuts for switching to desktops with fullscreen apps?

Coming from SL, one functionality that I used a lot was keyboard shortcuts to go to different applications.
For instance, I had assigned Mail to Space 2, iTunes to Space 3 etc.
Then it was possible to instantly go to Mail by pressing alt-2, to iTunes with alt-3 etc.
In Lion, it is possible to assign Applications to desktops, and use the same commands to go to these desktops. However, as soon as an application is 'fullscreened' it leaves its previous desktop, and cannot be reached with the old keyboard shortcuts.
My question:
is it possible to create a keyboard shortcut to switch to a desktop containing a fullscreen app?

This is quite possible. The way to do it is with keyboard shortcuts. If you check the appropriate boxes you can use a keyboard combination of Control and the Desktop #. It makes it very easy to swtich between desktops.

Looking for graphic cards compatible with the basic G5

Help!!
Went to the Apple Store to see if my G5 (M9020LL/A) which is the 1.6GHz PowerPC to see if it was compatible/could drive the 30" cinema display. They assured me my G5 could handle the large display. I have OS 10.5.8, iLife 09, 1 TB HD, 4GB RAM, NVIDIA GeForce FX 5200 Ultra with 64MB DDR SDRAM for the 8x AGP Pro slot.
The display arrived, I get picture but not resolution. Searched for a video/graphics card that was compatible. The ATI Radeon 9600 Pro PC/Mac with 256MB was recommended. I purchased one but can only get it to work with a safe boot. Get resolution but iPhoto cannot do the photos in full screen mode. But I can get full screen photos in screen saver mode?!
Apple support states they only recommend/support two cards for my model, the Radeon 9600 @ 64 MB, 2480X1326 res or the Radeon Pro, 128 MB, 2480X1326 res.
Has anyone had a similar problem with the Radeon card 9600 Pro PC/Mac with 256MB? Does anyone have a solution as to which card would be compatible with my G5 and get 2560X1600 res?
Any suggestions? Thanks you for your help!

Hi-
Welcome to Discussions!
Apple support states they only recommend/support two cards for my model,
Those were the only two cards offered at the time, so that is their "official position". You may safely ignore them..... even though they lied to you regarding the 30" ACD and your machine.
Has anyone had a similar problem with the Radeon card 9600 Pro PC/Mac with 256MB?
Often reported here on the forum.
Not a good card. If it works, fine, but many report as you do....Safe mode only.
The G5 can use any 8x AGP graphics card that was available in any AGP model G5.
OEM Mac cards with dual link DVI for the 30" ACD are:
Radeon 9650
Radeon X800XT
Geforce 6800 GT DDL
Geforce 6800 Ultra DDL
A flashed (converted WinPC card) Geforce 7800 GS may also be used.
Any of the above cards can be found on eBay/Apple Components.

My pause forward and backwards button wont work. Are there any handicaps that i can use with the middle button?

My buttons dont work and i wanted to know if there are any substitues that i can use with the home button.

Nope, it either needs to be plugged in or turned on with the power button.
A replacement iPhone 4 is $149, but at least the whole phone is replaced.

All ipod microphone adapters should work!

Are there any plans for Firefox Sync to include the customisation of the toolbar?

It's frustrating that Firefox sync doesn't include toolbar customisation data. It's otherwise a great piece of functionality that means when installing Firefox I don't have to set anything up apart from remembering to rearrange the buttons to my preference. This also goes for whether the menu and bookmarks toolbar are displayed.

hi gsoper, i've asked in the firefox sync channel about this and it's not something that is on the roadmap for sync at the moment, as that would be difficult across versions, platforms, when add-ons differ, and so on...

How do I fill color into an object drawn with the brush tool?

I'm watching a tutorial to learn more, and one think I still don't know is how to fill something with color that is drawn out via the brush tool. Say I draw a black circle and want to fill the color to green. I'm not talking about Live Paint were you select an object. I see in the tutorial the guys selects some tool but I can't see what it is.

You can fill any closed path by simply setting its fill color in the color palette... Paths can be smoothed with teh smooth tool. Please refer to the online help for specifics. Just watching tutorials doesn't necessarily teach you everything....

How to remove event handlers for a content type currently in use?

Hi,
We had a SP 2007 solution that managed event handlers as described in
Brian Wilson's blog regarding event handlers. We then did a in-place upgrade to SP 2010. It so happend that we wanted to remove some of our old event handlers and this is where our problem started. We managed to delete event handlers
(SPEventReceiverDefinitions) for
Site and List by using the ui from Brian Wilsons feature "Manage Event Handlers" (ref the link above), but not anyone at all for
Content Types... It simply wouldn't be deleted
(remove was grayed out in the ui).
We then tried to do it by code. Below is a code snippet illustrating how we tried to delete the event handlers for content types:
using (SPWeb web = properties.Feature.Parent as SPWeb)
string targetClassName = "targetClassName.";
web.AllowUnsafeUpdates = true;
// Removing Content Type event handlers
foreach (SPContentType ct in web.ContentTypes)
for (int i = ct.EventReceivers.Count - 1; i >= 0; i--)
if (ct.EventReceivers[i].Class.StartsWith(targetClassName))
ct.EventReceivers[i].Delete();
ct.Update(true);
web.Update();
The Content Types are not sealed and are
not readonly. When debugging, we can see that the
Delete() method are called on one of the Content Types we wanted to delete event handlers for. We noted that the
ct.EventReceivers.Count remains the same, before and after Delete() is called. We did not get any exceptions when running this code.
When running the code a second time and debugging again, we see that the very same Content Type still has the very same event handler attached... As in, it wasn't deleted....
We also tried to delete the event handlers through PowerShell as described
here in the post by Per Jakobsen. However, the script did not really seem to find any EventReceivers... We tried to write the
$site.AllWebs | % {$_.Lists} | % {$_.ContentTypes} | % {$_.EventReceivers} list to file, but it was empty.. We did however get a long list when writing $site.AllWebs | % {$_.Lists} | % {$_.ContentTypes} to file. We could then in
that file see the event handler references we want to remove registered to our Content Types, as we did during code debugging earlier on. So PowerShell might still be the way to go here...
So, does anyone know if there is a way to force this delete through, either by code, PowerShell or some other means? Any help regarding this matter would be very much appreciated :)

Hi,
For your information, there's two versions (at least) exists for each content types. One is Site Content Type - exists in Root web and another is list content type. Once you add a content type to a list, a copy of the site content type is taken and stored
in the list. If you update the site content type, it may or may not affect the list conten type. So make sure you are updating the both - site content and list content type. Once you update site content type with passing paramater true to 'ct.Update(true)',
the list content types are supposed to updated too.
Thanks,

Are there any shortcuts for creating Value Object Classes?

Hi,
I'm using a Remote Object to connect to my server
(pyAMF/Django). I'm getting stuck with the creation of Value Object
Classes. It doesn't seem very DRY to have a class on my server
representing the data model and then have to recreate that class
and all its properties in my Flex app.
Are there any shortcuts for creating client side VOs from
server side data?
I was thinking about declaring an empty VO class in Flex, and
then dynamically assigning/casting my Proxy object to that class.
It seems like that approach may cause problems for the Flex
compiler though.
Any hints?
Thanks!

One thing that has helped me in that area is a free tool from
Farata Systems called
DTO2Fx. If you're using Java and Eclipse, it's a great time saver.
You simply install a (very lightweight) Eclipse plugin, add a
single annotation to your Java VO classes, and it automatically
generates your Flex VOs. It even creates a base and extended
version of each VO on the AS3 side so you can add code to the
extended VO without fear of having your changes overwritten when it
regenerates your Flex VOs.

gives instructions and a download link. I had it up and running in
my application in less than 30 minutes!

serializer).

A way to access SVG event data for an object?

Is there a way to access the SVG event data for an object through scripting?

post this in the correct forum - you will get a better response (btw the correct forum is KVM)
to answer your question - any extra functionality above the MIDP1.0 specification will be manufacturer specific (and as such hardware dependant)
I only know 2 of the APIs extensivly (the Nokia and Siemens) neither of these offer access to the phonebook or the message folder (it would be a security risk) I don't think they provide the cell id either.
and no, there is no way to access the cellular phones OS. (on any phone!) it would completely destroy the purpose for having java on the phone.

Hi Bala!
The ways to get documents into RE-FX are described here:
http://help.sap.com/erp2005_ehp_03/helpdata/EN/fc/7f383b1b793821e10000000a114084/frameset.htm
RE-FX
-> Master Data
-> Document Management
The easiest way seems to be Business Document Navigator (BDN).
Hope that helps a little.

Don't know. You have not told us what system you have.

Are there new updates for camera raw for Lightroom 4, or only for Lightroom 5, as in 5.3 ?

Are there new updates for camera raw for Lightroom 4, or only for Lightroom 5, as in 5.3 ?

There will be no further camera support updates for Lightroom 4 beyond what is already listed in this table.
http://helpx.adobe.com/creative-suite/kb/camera-raw-plug-supported-cameras.html
Only current versions of Lightroom (currently Lightroom 5.3) will have further camera support added.
If you need to work with Raw files from new cameras you'll either have to upgrade to Lightroom 5 or join the Photoshop Photography Program (to get PC CC + LR5 + extras) or convert to DNG using Adobe's free DNG converter.

Are there fewer movies for rent, pushing purchasing?

Why are there fewer movies for rent via itunes on my AppleTV? Movies that are available for rent thru other services (windows, amazon, etc) are only available for sale in itunes. I don't want to purchase movies, I want to rent them as I previously have done for the past 2 years with my AppleTV. Anyone know what's going on?

I think this is a better question for the iTunes forums (as opposed to the ATV forums) since it's more specifically an iTunes question.
