How to determine the pixel positions of a line profile

Hello,
I was wondering if there was any possible way , when using the NIVison line profile, to get information on the actual position of each and every pixel the line profile used for its intensity values. Because i am using line profiles to reconstruct an image and i am getting pretty bad aliasing!

Hi Big_Al,
The Line Profile function is based around the IMAQ Line Profile VI, which takes a two parameters; a reference to the image we want to analyse and the co-ordinates of interest. It returns Line Information, the Global Rectangle, and our main value of interest, the Line Graph.
The Line Graph
This is a standard LabVIEW waveform cluster which is made up of three components: x0 (The initial x position of the selected line), dx (The increment value, which will default to '1' as we can't have half a pixel/two pixel voids in images) and finally Pixels Line which is an array of the pixel values we receive.
Now, since we know the start position of the line (x0), we can simply iterate through the Pixels Line array to grab these invidual values per pixel. For example, if the line was five pixels long, Pixels Line would be comprised five elements. The first (0th) position in the array will be the x0 pixel position, then after that we'd have the x0+1 pixel value etc.
Using this information, we can infer the positions of each of these pixels.

How to determine the u2018equivalent position of the same organizationu2019?

Hi,
"Position change is a transfer from one position to an equivalent position within the same org reporting structure and under the same chief position"
How to determine the u2018equivalent position of the same organizationu2019?
Cheers.

u can identity the position with help of the Holder
say for ex: A is the holder of the Position for Executive now the user performent an event called change of position so he changed to Manager (here we can find the chageing on the basis of some parameter so i have taken holder as Parameter as we dont know which has changed or wht has changed)
in this case we can use the report RHDESC20 se38
not an exact solution for ur question
will try to find some other way

How to determine the chief position?

Hi all,
How to determine whether the position is chief or non-chief?
Thanks.

Check if the position has any 012 relationship with any orgunit.
If so then it is cheif. You can check hrp1001 table with 012 relationship you will have an idea.
You will see that if for a given position otype = S
objid = position no is there any relat = 012 in the current period in table hrp1001.

This may be a basic question... but in InDesign, how does one determine the pixel size of a text box? Specifically, we need to write text to specifications of 600 pixel width, and have no idea a) how to scale a text box to specific pixel width, b) how to determine what word count we can fit in, and c) how to do it in a table? Thanks!

Set your ruler increments to pixels Preferences>Units & Increments. You can fill the text box with placeholder text Type>Fill with Placeholder text and get a word count from the Info panel with Show Options turned on from the flyout.
From the Transform panel you can set a text box's width and height

How can determine the duration of an audio file

Hi,
i'm making speech recognition project using java. i can capture sound by michrophone and playback it. the type of the sound is .wav.
my question is how to determine the recording duration (for example: determine the duration for 0.25 second) because i must recorded syllable,the assumtion is needed less than 0.5 second to say a word. and then.. can this wav file be changed into... binary or integer ?
thanks for your help

FYI I'm newbie in Java,
Yes, I want to limit the audio file lengths to a certain value. What should I do?
I have read wav file using an AudioInputStream, for audio format I'm using sampleRate = 8000.0F and sampleSizeInBits = 8. My friend said if I used 8 bit for sampleSizeInBit (resolution in amplitude) the binary file should be -128 till 127 in range according to the bit. I try this code and the result is binary file which is zero, positive, and negative.
the code
try{
audioInputStream.read(audioBytes);
for (int i=0; i<audioBytes.length;i++){
System.out.println(audioBytes);
catch(IOException ioe){
System.out.println("Error"+ioe);
I'm not sure that the code is right, but it works. Should I change the audioBytes into integer before? I try this code but it doesn't work.
int a = new int[audioBytes.length];
for (int i=0;i<audioBytes.length;i++){
a[i] = new Byte(audioBytes[i]).intValue();
this binary file has been printed in console (Im using texpad). So, how I can write that to file.txt? I'm using FileoutputStream but it doesn't work correctly. Here is the code
FileOutputStream fos = new FileOutputStream(strFilePath);
{audioInputStream.read(audioBytes);
fos.write(audioBytes);
catch (IOException ioe){
System.out.println("Error"+ioe);
When I open file .txt is read as character like this üüüüüüüüüüüüûüüüûüûûû ||||||| ||||||| ||||||||||||||||||||||||||||| ےےےےےےےےےےےے (like using alt plus number)

How to get the Useru2019s position when the user doesnu2019t have CP relation

We have a custom program which will add / delete attributes (In transaction PPOSA_BBP). It is working fine for users which were assigned with CP relation But it fails for users which doesnu2019t have CP relation (since we are getting the position of users form HRP1001 then we are retrieving the existing attributes based on the position after that updating the attributes) as we are getting the position from HRP1001 it fails for users were no CP relation.
Help us how to get the Useru2019s position when the user doesnu2019t have CP relation. Suggest us any function module or how to query the HRP1001 or some other table if exists
Regards
Paul

Hi Paul,
Have a look at these tables.
Using table BUT000 the central business partner data are stored, f.e. partner type, partner names, partner number, partner guid, person number, etc. In table BUTBKK the bank data to a business partner are stored.
Central business partner address data
The table ADRC is used for the address of a business partner. Table BUT020 links the business partner number with the address number. Using table BUT021 several addresses to a business partner with different usages (modes), f.e. correspondence or delivery address, can be stored. The personal data of a business partner person are stored with key person number in table ADRP. The person number is assignd to a business partner person in table BUT000. Communication data of business partners as e-mail, telephone, fax, etc. are stored in the tables ADDR1 u2013 ADDR12. The business address of a contact person or an employee consists of the organization address (company resp. org.-unit) and of an address addition, which describes f.e. a building, a room number, etc. The address addition is stored in table ADCP and is identified by the keys address number of the organization address and person number.
Relationships between business partners
Table BUT050 contains the relationships between a business partner organization and a business partner person using relation types. The relation types are defined in table TBZ9, f.e. the relation type u2018has employeeu2019 corresponds to identifier u2018BUR010u2019, the relation type u2018has contact personu2019 corresponds to identifier u2018BUR001u2019. Table BUT051 stores communication data of a contact person relationship (compare to table ADCP). Table BUT052 stores several address numbers to one business partner relationship (including a standard flag).
Hope this helps,
Kind Regards,
Matthew

How to determine the ROWNUM in a Master Detail Form

Hello,
I am working in a Master Detail Form with Orders and Order Items Information; and I created a process that allows the users to select a Product ID on a tabular form, and the next column is populated automatically with the Product Description.
To achieve that, I followed some instructions by Denes Kubicek (http://apex.oracle.com/pls/otn/f?p=31517:241), but my case is slightly different:
<ul>I am using a wizard-created tabular form, instead of a manual tabular form; and </ul>
<ul>Instead of using another page as a Popup to pass the parameter of the ROWNUM, I am using a plug-in called “Tabular Form Super LOV” which is a modified version of the SkillBuilders’ Super LOV that works on Tabular Forms. </ul>
The Product ID is returned in the correct row by the plug-in; but in the case of the Product Description, it is always returned into the first row; and my problem is that I don't know how to determine the row where the user clicked to call the plug-in.
I set up an example in apex.oracle.com in case someone would like to look at it:
Workspace: ediazjorge
Username: test
Password: test
App Name: Sample App
App Number: 1550
BTW, I am using Apex 4.1.1.00.23 and Oracle DB 10.3.2.
Thanks in advance,
Erick

Hello VC,
Thank you for your time and help.
Unfortunately, it is still not working properly:
1. When the Popup LOV opens, the first row of the tabular form is 0, the second row is 1, and so on. How can I assign the values starting with 1 and in the format *0001* ? (I am still a novice on Apex and new to JavaScript :-), sorry about that).
--2. Also, when I close the Popup LOV, the value of P1_ROWNUM is ‘undefined’ again so I'm not sure if the Product Name column will be populated.--
3. And finally, you are using the jQuery Selector uPopupLOVIcon, which is an attribute of the Cloudy Theme. In my real application (Apex 4.1.1.00.26), my element looks like: *<img src="/i/lov_16x16.gif" width="16" height="16" alt="Popup Lov" alt="List" style="vertical-align:middle;" align="middle" />*. What do you recommend me to use as a jQuery Selector?
Again, I really appreciate your help and time. I think you solved the most difficult part.
Thank you so much,
Erick
Update: I just found out that the problem with my comment 2 is because I didn’t delete the previous dynamic action that set the value to P1_ROWNUM.

How to determine the mount point for directory /tmp ?

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
I am installing Grid infrastructure. I am on step 7 of 10 (verify Grid installation enviroment) and get this error:
"Free Space: Rac2: /tmp"
Cause: Could not determine mount point for location specified.
Action: Ensure location specified is available.
Expected value: n/a
Actual value: n/a
I have checked the free space using the command:
[root@Rac2 /]# df -k /tmp
Output:
Filesystem 1k-blocks used Available Use% Mounted on
/dev/sda1 30470144 7826952 21070432 28% /
As you see above, the free space is enough, but could not determine mount point for /tmp.
Do any folk understand how to determine the mount point for directory /tmp ?
Thanks.

I have just checked "/home/oracle/.bash_profile". But in my computer, there is no "oracle" under /home directory.Is this your first time Linux and Oracle installation? I had a brief look at your referenced link. The reason why you do not find a "oracle" user is because the instructions use "ora11g" instead, which, btw, is not standard. The directories of your installation and your installation source can be somewhat different from known standards and you will have to adjust it to your system.
My best guess is that you have either missed something in the instructions or you need to ask the author of the blog what is wrong. The chance to find someone here who has experience with these custom instructions is probably unlikely.
I suggest you try to locate the cluster verification tool, which should be in the bin directory of your grid installation. Alternatively you might want to check the RAC, ASM & Clusterware Installation forum: RAC, ASM & Clusterware Installation

How to determine the field size

I am going to make a multiplatform application that hopefully
will run on linux and windows 2000.If the os is 2000, then I will use
vb.net/aspx else I'll use java servlets. I make the connection
to the web server ( through HTTP) not directly to database server.
So, the resultset will be stored in the String object. The columns
will be separated by delimeter. Our problem is how to determine
the size and type of the fields of mssql,oracle and postgres database
so that we can include it in the String object.
Ex.
String sResultSet=new String();
ResultSet rs=statement.executeQuery(sSQL);
while(rs.next()){
sResultset=sResultSet + rs.getString(field1) + "||" + rs.getString(field2) + "||";
vertical bars acts as delimeter
supposedly this is the code:
sResultset=sResultSet + rs.getString(field1) +"_" + rs.getFieldType() + "_"+
rs.getFieldSize() + "||" + rs.getString(field2) +"_" + rs.getFieldType() + "_"+
rs.getFieldSize() + "||";
supposedly this is the code if rs.getFieldType() and rs.getFieldSize() methods are existing
Anyone can give me an idea how to get the field type and field size of the database?
thanks in advance

Yes, but I dont know how to do it.
Can you give me an example of using it.
Thanks in advance

How to determine the type of the jobject... similar to instanceof

hi,
I would like to know how to determine the jobject reference of an instance is of which class.
this is something similar to instanceof we use in java.
is there any thing like 'instanceof' in JNI. if there how to use it?
i got this as objective question for which answers were(i do not remember exactly)
1.instanceof
2.assignedto
i could nt het much help in googling.
thanks in advance

Hi
The JNI provides a native version to the java instanceof operator, this function takes two arguments
an object refrence and a class refrence and reports JNI_TRUE.
jclass myclass = env->FindClass("your class name");
if(env->IsInstanceOf(obj,myclass) == JNI_TRUE)
// obj is of type myclass

How to determine the solution's ID in absl?

Hello Community,
I have a simple question yet I fear there is no simple answer (possibly no answer at all).
The question is:
Does any body know ways how to determine the ID (e.g. Y123ABCDY_) of the solution the code is running in?
My use case is the following:
We have a solution template which will be deployed in different customer tenant.
Thus, each deployment will have a different solution ID.
Now, somewhere in code, we generat PDFs using the OutputManagementUtilities.GetPDF reuse library.
This method requires the form template code of the pdf to be generated as a parameter.
However, this PDF form template code is composed of the solution ID and a fixed suffix.
Thus, currently I need to modify the absl code in each customer installation to manually modify the form template code prefix to the solutions solution ID.
Therefore I'd like to construct the form template code in absl but for this I need a way to determine the solution's ID.
Any ideas?
Best regards,
Ludger

Hi Fernando.
After reading your post I initially thought "what is the ObjectTypeCode" supposed to do any good to determine the solution ID"?
Using the Object Type code of a custom bo is indeed a way to solve this problem.
With a little additional code I can extract the relevant solution ID part from there.
Thanks for the hint, that was really useful.
Best reegards,
Ludger

How to determine the maximum allowable length of a filename for Window ?

Hi all,
Could I know how to determine the allowable file length (the length of the absolute path) for a file in Window environment?
Due to some reason, I generated a zip file with a very long filename ( > 170) and put in a folder(the length of the folder path around 90). The length of the absolute path is around 260.
I used FileOutputStream with the ZipOutputStream to write out the zip file. Everything is working fine while i generating the zip file.
However, while i try to extract some files from the zip file i just created, i encountered the error
java.util.zip.ZipException The filename is too long.
I am using the class ZipFile to extract the files from the zip file like the following
String absPath = "A very long filepath which exceed 260";
ZipFile zipF = new ZipFile(absPath); //<-- here is the root causeIs it possible to pre-determine the maximum allowable filepath length prior i generate the zip file ? This is weird since i got no error while i created the zip file, but have problem in extracting the zip file ......
Thanks

Assuming you could determine the max, what would you do about it? I'd say you should just assume it will be successful, but accommodate (handle) the possible exception gracefully. Either way you're going to have to handle it as an "exception", whether you "catch" an actual "Exception" object and deal with that, or manually deal with the length exceeding the max.
