Speed and course methods for location object don't work

I am attempting to use the Location API (JSR 179) to extract the course and speed (getCourse() and getSpeed() of Location object) of the user on a Nokia N95. However, no matter what speed I am travelling at or how good the GPS signal is, NaN is returned. Other fields like latitude and longitude work fine. Why is this? Were these methods never implemented? The problem clearly does not lie with the GPS or the device, as the built-in Symbian applications have no trouble returning course or speed information. Why do these methods not work?

Hello,
Since you provided no code to show what yu are doing, and you don't give any indication of what " i have some troubles" means, I'd Bing "C# playback .vob files".

Tiling and collision methods for this app

I plan on making a game where the player travels down though a level. I have created basic player/objects collision games using AS2 & Mclips for browser/PC and some basic AS3 apps also, but I want to focus on making this one to run well/fast on iOS and Android via flash/AIR.
The goal will be for the player to avoid colliding with rock/tiles. There will not be too many enemies to track but a few powerups may be on the rock edges to pickup.
Can someone give me any suggestions/links for current Tiling and Collision methods for this environment? Should I use starling?

Thanks Glad, I hear that a pixel perfect collision method like bitmapdata hittest can be a tremendous overhead in CPU time, but I guess I will have to try it and see.

As long as the profiles are different (ex. HID vs AD2P) you will not have any issues. But say if you try to use 2 keyboards at once, it won't work. Or 2 headsets at once. Your scenario seems fine.

About report groups and read programs for the object EC_PCA_SUM

Hi Friends,
Hope every one is doing well..!
I've an issue with the report groups and read programs for the object EC_PCA_SUM. As we know that the report groups and read programs available for this object in the application customizing are used to analys the archived data.
That is these programs comes into picture after the archiving operation.
For more information, you can visit the below web site:
[http://help.sap.com/erp2005_ehp_03/helpdata/EN/e4/69f353b75a11d1b5850000e82debc6/frameset.htm]
Now, my question is how would I check the code for these analysing programs available for this object. I can't see this in SE38.
Thanks to reply for this..
Full marks will be awarded.
Regards,
Shamim

Hi Lakshman,
Thanks for the reply.
Hi Deiter,
You're right.
Your provided transaction "GR55" helped me to find out the program name for a particular group. However, these are just Write and Painter reports.
But can you please let me know the functionality of these report groups ?? what are these used for ???
Do we have these programs for other archiving objects like CO_ITEM,CO_ML_BEL,MM_MATBEL,CO_ORDER,
PP_PLAN,PP_BKFLUSH ??
More points will be awarded.
Thanks a lot.
Regards,
Shamim

Can we hav call transaction and session method for an application

can we hav call transaction and session method for an application ?if yes how?

Hi ,
You can. If Call Transaction fails, a batch input session can be created.
Check this example-
Call the transaction. Messages from Call Transaction are stored in the
internal table messtab
CALL TRANSACTION 'LT01' USING bdc_tab MODE 'N' UPDATE 'S'
      MESSAGES INTO messtab.
IF sy-subrc = 0.
Call transaction successfull, get the number of the Transfer Order that
was created
    LOOP AT messtab.
      IF messtab-dynumb = '0104' AND messtab-msgnr = '016'.
        w_transportorderno = messtab-msgv1.
      ENDIF.
    ENDLOOP.
ELSE.
Call transaction failed, create a batch input session instead.
    PERFORM open_group.
    PERFORM bdc_insert USING 'LT01'.
    PERFORM close_group.
ENDIF.

Sookshma

Flash learning interaction and Course Builder for CC products?

Hi all, Could anyone advise me where I could get extension Flash learning interaction for Flash CC and Course Builder for Dreamweaver CC? Sometimes their use and after stopping the development of eLearning Suite I anywhere on the Adobe site found these extensions.
Thanks for any response.
Yarik

You would be better advised to ask these questions on the Flash or Dreamweaver forums. This is the Adobe Captivate forum.

Labview programers, for your safety don't work for holotpics in Switzerland

Ni programmer, for your safety don't work for holotpics in Switzerland, the chairman is a bad guy:
he swindles National instruments by buy matérial on the black market
and he don't pay its employes and a lots of others bad things.

Never heard of the company, but if they don't pay their employe(e)s, then there won't be anyone at all working there soon.
Otherwise, NI, delete this stupid post please.
Personal opinions of this sort are trash and deserve to be removed.

My current version of Chrome is having problems, too! It's so annoying. Anyone have any suggestions now? I basically can't view or download any PDFs because of this.
Does anyone else think this is a problem not only with Adobe? I would think Apple would have something to do with this? Wouldn't they get some idea from the developer versions that no browser can open PDFs while running Lion!? Pretty bad customer service on the part of a company that prides itself on being VERY customer-friendly. Wouldn't you say?

Make an appointment with the Genius Bar at your Apple Store. If they determine there is an issue with your iPad, it will be replaced.

My iphone keeps blocking in a "boot" mode... blackscreen with apple logo... the restarting (home and power button for 10 sec) doesn't work.

My advice is to try not to treat this like it is a paid service provided by compensated professionals. Ask nicely and one of the nice folks here might take some time out of their weekend to offer advice.

I just upgraded to os 5 and now my non apple apps don't work. They will not launch. Anyone seen this before?

Have you tried basics from the manual?
Restart.
Reset.

If I upgrade to LION and Word, PP, EpsonScan, Dropbox etc. don't work anymore - what can I do?

Even if you could upgrade, Lion does not support Power PC apps / Rosetta.

New Macs come with Lion pre installed. If you can purchase one at some point that way you'd still be able to use the apps you mentioned on the PBook and have another Mac running Lion.
