Table on a curved path

I'm trying to make a table on a curved path like this:
Intuitively, I create my curve, I choose type on path tool, and once I have the type cursor blinking on my path I select Insert table.
No matter how small I make the table, i.e. 2 rows, 1 colum, I get overset text error that doesn't go away if I scale the path.
Is there a different way to do this?

I don't think tables work on a path. You'll probably need to make a separate path for each line.

Moving in curve path

Hi,
Any one Please guide me how to move a object in a curve path
using script.......
thanks,
shanthi.

Hi Shanthi,
you could use the parametric representation of the equation
of the curve. The attached code will move your movie clip in a
circular path.

Dynamic Update of Curve Path

I am using Photoshop CS6. I created a curve path and a "new" layer that contains the brush stroke applied to the path. I want the brush stroke to dynamically update when the path is modified. Can this be done?

With the exception of extremely simple strokes (Shape Layer’s Stroke or Layer Style Stroke applied to a Layer with a Vector Mask, and those may have issues with unclosed Paths) you should follow Mylenium’s advice and use another application.

Learning curve / path from Go Live! to Dreamweaver; is it worth it?

Learning curve / path from Go Live! to Dreamweaver; is it worth it?

I'll be blunt, it's not worth "learning Dreamweaver" at all, if you don't understand html, css and basic javascripting prior to opening the program.
Without those three things, DW becomes a monstrous time sink that allows you to produce rudimentary websites that your viewers and peers will scoff at.
Now, if you do understand HTML and CSS (and to a lesser extent, javascript) running the DW tutorials from the Adobe site (hit F1 while in DW to open the Help site) will help you get up and running in no time and you'll be able to create some fairly advanced sites relatively quickly with current internet standards-compliant code.
If you don't understand code and refuse to educate yourself, as Ben says, Muse would be the way to go.

Applying gradient to a curved path...

Is there a quick and dirty way to apply a gradient to a curved path, such as a logarithmic spiral?
Thank you for the help!

I realize it has been quite a while since this was originally posted...but I came across it and have had to do this exact thing before: applying a gradient to a spiral.
This is what I came up with. Just thought someone might find it handy.
Depending on the Steps and Distance, the final results can look quite smooth.
The Blend colors can always be edited by selecting and changing
the color of the original objects within the blended object.

Make Bezier curve path in plug in

I could get the codes to draw paths in automation plug-in with the listener log file. But some paths are not shown in it. Such as the Bézier curve path.
I try to use the getter plug in. The fuction "SPErr PlayGetting Work Path Info" is to draw path. But the code like this is not work rightly.
error = sPSActionControl->StringIDToTypeID("Getting Work Path Info", &runtimeEventID);
if (error) goto returnError;
error = sPSActionControl->Play(&result, runtimeEventID, desc00001040, plugInDialogSilent);
if (error) goto returnError;
Could you tell me how to draw Bézier curve path? How to used the codes from "getter" plug in rightly?
Please help me. Thanks a lot.

Maybe post the question in a forum for Flash.
I can't show you how to do it, Sorry.

Curve path in adobe edge

Since adobe edge cannot do curve path like adobe flash, is that possible we do curve path in flash then export to adobe edge?
Or more directly, export that flash file into adobe indesign for DPS?

Motion on a curved path

I've been using the motion attribute found in the edit effects window. I've noticed from time to time that I've created a curved path that the image will follow. Up until now I've deleted the anchor points and started over.
Now, however, I'd like to have an image move in a less linear fashion, but have no idea how I stumbled into what I'd previously thought of as a problem.
Any ideas how to do this on purpose?

Andy,
For me, the easiest way to do this is to choose the main points (hence the name Keyframes) of the motion path (note: this is not like Text on a Path, drawn with the Pen Tool in many programs), and then use Continuous Bezier for those Keyframes This "smooths" everything out. I personally use the X-Y coordinate numbers, rather than drag the Bounding Box, but that is just me. If you need to map things out visually, I'd go to PS/PSE and do a "guide" for that motion path, with the Pen Tool and Stroke that Path. Save_As a PSD and Import that guide. Now, you still have to set your Keyframes, as you cannot tell the program to "follow the Path," but you have the guide to go by. I did similar, when a client's log had to follow a sine wave on an O-scope, as though it was the trace beam.
Good luck, and hope that this helps.

Can we delete the archived RS tables data in unix path?

Hi Experts
As you all know that when we perform RS table archiving we setup a Logical file path 'ARCHIVE_GLOBAL_PATH' pointing to the physical path '/usr/sap/<SYSID>/SYS/global/<FILENAME>' in unix system.
Here we have our RS table data in the unix path and this logical path will make sure that there are no problems with requests status.
Now our unix path has grown in size hence we would like to delete some archived data from this path. Could you pls confirm if we delete the data from this unix path will there be any problems with the requests status?
Simply can we delete the RS table archived data from the unix file path??
Thanks!!

Hi All
Any idea about this would be appreciated.
Thanks!!

A column in a table has physical file path (I want to get file size of those docs from the OS)

Experts!!
I have a table that holds the physical file path of files in one of its columns. It does not give a link, just the physical file path.
For example,---- C:\bu\test.pdf and let us say the file size is kb according to the OS.
Is there any way I can obtain the file size of the files from the physical path?
for example, the file size of the test.pdf file in the example here using t-SQL?
Much Appreciation

Hey there... thanks for the response......I found the following as a solution for my problem. But my problem is the SP created using the method needs a directory as a parameter. How can I pass the directory from a table that holds my directory?

Objectives
To show that when serial scans are performed on database built on Solid State Disks (SSD) compared to Magnetic disks (HDD), the performance gain is far less compared to random reads with index scans on SSD compared to HDD
Approach
We want to read the first 100 rows of tdash table randomly into buffer, taking account of wait events and wait times generated. The idea is that on SSD the wait times will be better compared to HDD but not that much given the serial nature of table scans.
The code used
ALTER SESSION SET TRACEFILE_IDENTIFIER = 'test_with_tdash_ssdtester_noindex';
DECLARE
        type array is table of tdash%ROWTYPE index by binary_integer;
        l_data array;
        l_rec tdash%rowtype;

                  WHEN NO_DATA_FOUND THEN NULL;

In comparison with no direct path read, there are 1,218,651 db file scattered read waits with total wait time of 3,770 seconds. My understanding is that direct path read can use single or multi-block read into the PGA. However db file scattered reads do multi-block read into multiple discontinuous SGA buffers. So it is possible given the higher number of direct path waits that the optimizer cannot do multi-block reads (contigious buffers within PGA) and hence has to revert to single blocks reads which results in more calls and more waits?.
Appreciate any advise and apologies for being long winded.

Hi Charles,
I am doing your tests for t1 table using my server.
Just to clarify my environment is:
I did the whole of this test on my server. My server has I7-980 HEX core processor with 24GB of RAM and 1 TB of HDD SATA II for test/scratch backup and archive. The operating system is RHES 5.2 64-bit installed on a 120GB OCZ Vertex 3 Series SATA III 2.5-inch Solid State Drive.
Oracle version installed was 11g Enterprise Edition Release 11.2.0.1.0 -64bit. The binaries were created on HDD. Oracle itself was configured with 16GB of SGA, of which 7.5GB was allocated to Variable Size and 8GB to Database Buffers.
For Oracle tablespaces including SYS, SYSTEM, SYSAUX, TEMPORARY, UNDO and redo logs, I used file systems on 240GB OCZ Vertex 3 Series SATA III 2.5-inch Solid State Drive. With 4K Random Read at 53,500 IOPS and 4K Random Write at 56,000 IOPS (manufacturer’s figures), this drive is probably one of the fastest commodity SSDs using NAND flash memory with Multi-Level Cell (MLC). Now my T1 table created as per your script and has the following rows and blocks (8k block size)
SELECT
NUM_ROWS,
BLOCKS
FROM
USER_TABLES
WHERE
TABLE_NAME='T1';
NUM_ROWS     BLOCKS
12000000     178952which is pretty identical to yours.
Then I run the query as brelow
set timing on
ALTER SESSION SET TRACEFILE_IDENTIFIER = 'test_bed_T1';
ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 8';
SELECT
        COUNT(*)
FROM
        T1
WHERE
        RN=1;
which gives
COUNT(*)
     60000
Elapsed: 00:00:05.29
tkprof output shows

It appears to me that my CPU utilisation is by order of magnitude better but my elapsed time is worse!
Now the way I see it elapsed time = CPU time + wait time. Further down I have

roughly 17.5/129759 = .00013 sec for single block I/O and 3770.02/1218651 = .0030 for multi-block I/ONow my theory is that the improvements comes from the large buffer cache (8320MB) inducing it to do some read aheads (async pre-fetch). Read aheads are like quasi logical I/Os and they will be cheaper compared to physical I/O. When there is large buffer cache and read aheads can be done then using buffer cache is a better choice than PGA?

Straight Path to Curved Path CS5.5

Is there a fast and simple way to make a straight path curved? I'm a FreeHand convert, and with it you could hold down the option key, click and drag the straight path (line) into a curve and control it fairly well.

I know, Larry.
I was merely joking about the thought of actually dragging both (two mice, one mouse and one stylus, two styluses).
Your posting stopped my (second) editing, which would have led to:
Just ClickDrag from the Anchor Point, and see the other one extend symmetrixcally; you may (repeatedly) let go and drag either (back in), leaving the other one as it is (not).

Getting points / curves / paths break down of shape

I'm trying to take a shape from illustrator and have the iOS graphics engine draw it without having to import the file. In order to do this, I need to somehow get a text break down of all the bezier paths / curves / points that comprise the shape so I can tell the iOS graphics engine the points that need to be drawn. Is there anyway to get a list of these points from illustrator?

Scripting would be an option.

Create File Table for Existing UNC Paths ?

Hi,
I have a files with in the server ( //Server1/Folder1) and (//server1/Folder2).
Now If I am create FileTable Database in the server ( server2 ) and how can I give filename path ?
Example :
I am going to create FileTableDB database in the server2 , it contains directory 'D:\'
CREATE DATABASE FileTableDB
ON PRIMARY
(Name = FileTableDB,
FILENAME = 'D:\Microsoft SQL Server\MSSQL\DATA\FileTable\FTDB.mdf'),
FILEGROUP FTFG CONTAINS FILESTREAM
(NAME = FileTableFS,FILENAME='\\Server1\Main\cfs')
LOG ON
(Name = FileTableDBLog,FILENAME = 'D:\Microsoft SQL Server\MSSQL\DATA\FileTable\FTDBLog.ldf')
WITH FILESTREAM (NON_TRANSACTED_ACCESS = FULL,DIRECTORY_NAME = N'FileTableDB');
GO
If I run above query then I am getting an error is " cannot be used for FILESTREAM files."
Please help me to solve this..

Hi Narsa,
The FILESTREAM data container for a database must be placed on an NTFS volume on locally-connected storage. Just like database data and log files, the directory cannot be on a UNC share. Even if you use UNC it will not work. FILESTREAM can be setup only
for locally attached storage (locally for the server).
There are more information about enabling and using FILESTREAM, you can review the following article.
