How to use a path (mask) as a guidance path for an object?

Hello,
I want to use a path / mask as a guidance line for an object. I know i can draw a mask, then cut the path parimeter and paste it into the the position, but that seems to come with all kinds of restrictions. For example; when i use that method, i can't make the object stop moving halfway trough the animation. Also i cant animate the object further along because the object starts to do all kind of weird things, like flipping horizontally / vertically.
I was wondering if there isn't just a function build in After Effects to track a path? Or a plugin?
Any help would be much appreciated
Thanks in advance!
Kind regards,
Yori

My keyframing skills are pretty developed, but all rules i know regarding keyframing seem to go out of the window as soon as i paste the path into my position parameter... How come it flips the object for example?
What i went to do is: have my object follow a path, then stop, move up a bit, stop again, and then follow another path, but i can't seem to get that done. Also, when i have animated the first path, and i put another keyframe 12 frames further AE makes up some kind of extra path which is supposed to fill the gap between the last keyframe of the path animation, and the next keyframe. I really don't get it...

What are the reasons for using absolute paths to embedded objects in word?

Hello,
hopefully someone can answer me the question why word always stores the absolute paths to linked objects? We use Word for documentation and these documents are stored in a version control system and sometimes several persons are working on a document. Because
of the absolute paths stored in the document all users would need to have the same directory structure so that the links would work for every person.
For linked objects it's not even possible to change the absolute paths to relative paths.
Additionally I would like to know what the difference between a "Graphic" and "Picture" object is. A graphic can be inserted by selecting "INSERT" -> "Pictures" and a "Graphic" doesn't seem to have a field
function and always uses absolute paths. "Graphics" can be inserted by selecting "INSERT" -> "Quick Parts" -> "Field..." -> "IncludePicture" and it's possible to use relative paths for "IncludePicture"
objects and it's possible to show the field function of a "Picture" object.

Martin

My doubt here is, Even i could not find this varaible in BEX formula variable, But could see this in BI Content path as mentioned in the above link. DO i have to transport this varaible , or i simply can activate it in production?
I just could find this in BI Content but not in MetaData Repository.

How to use imported paths from Photoshop/Illustrator as motion guides

Hi folks,
I've been raking the internet with no success for an answer to my question, but I've had no luck so far.
What I'm hoping to achieve animation wise is to have a shape move around a set path that was created in Photoshop. The reason being, it's a very specific shape (near enough a square but with curved corners and a chunk missing out of one of the sides), and I used the paths feature in Photoshop to create it and stroke the path for the smoothest possible effect. What I'd ideally like to do is import the same path I used to create the shape into Flash Professional CS6 and then use that same path to guide a small symbol around the edge of the square.
So far, I've worked out how to apply motion to a symbol through basic tweens, and then I can draw out a line using the pencil tool and apply that to the tween so it follows the pencil line instead of just going from point A to point B. The problem is, this looks awful...I'm not good enough with a mouse to create absolutely perfect shapes freehand, so I just want to be able to use the Photoshop path as my motion guide instead of having to make another one from scratch.
I've looked around for various importing methods, the most success I've had is exporting the paths to an Illustrator file, and then importing the Illustrator file into Flash directly. However, I have NO idea where these paths go when they're imported, or how to access them. If I import them to the stage, they seemingly disappear before I've even seen them, and if I import them to the library they just aren't there.
I could also do with a brief description of how paths work in Flash - I'm familiar with the Photoshop layout, what with the paths appearing in a panel next to the layers one (makes perfect sense to me, as you can just switch between the two panels to view whatever you want). I just don't understand how they work in Flash and what I should be looking for....
Many thanks in advance for any help!
Todd

I had a play around with some variations of this. What I can't grasp is why Flash won't recognise my shape layer as a motion path. I've tried breaking it down, that doesn't work... I traced it narrowly in Photoshop and imported it as a thin line with a gap (so essentially a line with two ends), and it comes into Flash as a bitmap or something of that sort. I found an option that traces the bitmap, and appears to convert it into a shape layer...I've managed to find the optimal settings so the line is joined all the way through apart from the start and end points. The only thing is, Flash seems to not even notice this as a guide layer when I apply it to the symbol I'm trying to animate. It just doesn't even notice it's there. The object moves straight from point A to point B in a straight line, the guide layer does nothing to adjust the motion... Is it not possible for the traced line to act as a motion guide? It's a shape, it is a single line with a start point and an end point, and there are no other instances of anything else in the layer - just the line and nothing else.
This seems way more difficult than it should be...I'm sure Adobe could have integrated a MUCH easier system for importing paths from Photoshop that actually exist in Flash rather than disappearing into some abyss instead!
Here is a screenshot of what I'm working with: http://gyazo.com/4c1046767e1ee8bf99f65751b9ba81b8
The long black oval is the shape I'm trying to animate. I've tried applying tweens to it while it's in shape form and while it's in every different symbol form, all to no avail.
The black line is what I'm trying to use as the guide. Having looked online, people seem to be able to just use the "paste in place" option and it somehow knows exactly what they mean and animates around the line perfectly. I tried that and it didn't work (no surprise there), and then I tried the motion guide layer setup and it also didn't work. I'm not sure if tracing a bitmap into a shape layer somehow removes any possibility of the line being recognisable as a line or something...could that be the case?
Is there a simple way to turn a shape layer (in this case the black line) into a motion guide that I'm missing? I thought just turning the layer into a guide layer would do the trick, but obviously not :/

How to use the same mask, stencil, etc., for multiple layers? Photoshop equivalent of masked group?

Hi I spent more than half an hour to search manual, forums, and Internet and still can't find the answer. Please help!
For example, in a comp with 5 or more layers I want to use the same mask or stencil or what ever can hide areas of the layers 2,3, and 4 but layer 5 and any other eventual layers below should not be affected.

Pre-compose the layers you want to mask and apply a track matte to the pre-comp using the mask. Think of pre-composing as an equivalent of creating a layer group.
Use Set Matte effect on each of the layers you want to mask. This is easiest to do if you apply set matte once and then create an animation preset to apply to the other layers. Just get set matte to do what you want it to do on the first layer, Select Set matte in the ECW or in the Timeline, then go to Animation>Save animation preset. Then select all of the other layers you want to apply the set matte to and apply the preset.
Put the mask at the bottom of the layers you want to mask and enable the preserve transparency switch, then nest this group in the composition with the other layers.
Here's another tip. You could define a custom color for all of the layers you want to use the matt on, then use the custom color for a group selection. This may make things easier down the line.

How to use semi-transparent mask on external swf?

I want to use semi-transparent mask on external swf for smooth transition. I'm using
clip.cacheAsBitmap = true;
mask.cacheAsBitmap = true;
clip.setMask(mask);
Everything works fine. But when I use
loadMovie("http://www.url.com/movie.swf", "_root.clip");
clip.cacheAsBitmap = true;
mask.cacheAsBitmap = true;
clip.setMask(mask);
it doesn't work... what am I doing wrong?

well if your loadMovie is on the same timeline as the code you are setting as mask, then you dont need _root.
And sorry, I forgot there was an issue with masking the main mc that loadMovie is loading into. So what I did was put clip inside another mc and called that mc "container" so then my code would look like :
masker.cacheAsBitmap = true;
container.cacheAsBitmap = true;
container.setMask(masker);
container.clip.loadMovie("movietoload.swf");
download the two swfs attached, and open main.swf to see.

How to create search path for the file on the desktop..

hello experts..
      I have used gui_upload module to upload the data from flatfile to the internal table, in that how can i create search path for the file selection in the selection screen, also please help me the code to update the ztable.
thanks

HI
If iam not wrong you want to select a file from a location that you don't know so if this is ur problem then use the function module
F4_FILENAME
this FM helps to locate and select the desired file from the system.
Sample code that you can check is
How to get windows filename
PARAMETERS: lv_file LIKE rlgrap-filename.
Method 1
    CALL FUNCTION u2019KD_GET_FILENAME_ON_F4u2019

    STATIC = u2019Xu2019
    CHANGING
    FILE_NAME = LV_FILE.
Method 2
CALL FUNCTION u2019F4_FILENAMEu2019

Using relative path for in file/ftp adapter

Hi All,
How to have a relative path for file/ ftp adapter's inbound/outbound operation?
Example: Consider $ORA_HOME = /home/oracle --> This environment variable can be different on different machines
i want to drop a file in to $ORA_HOME/folder1/folder2 (Or poll for a file).
<partnerLinkBinding name="FTP">
<property name="wsdlLocation">FTP.wsdl</property>
<property name="out_dir" type="LogicalDirectory">What do i write here???</property>
<property name="retryInterval">60</property>
</partnerLinkBinding>
if i cant configure this in partner link section or in activation agent sction, how else do i achieve this?
i am using 10.1.3.* version.
Thanks in advance.
Roshan.

You can achive it using the deployment scripts if the directory is changing on the basis of the environment
If you want to change at run time than you can use the jca properties to set using the variables at runtime.
