How to determine the name or type of a control in a existed VI?

I got a couple of VIs other engineers created before. There are a couple of controls I can not tell the type or name of that control.
I used LabVIEW ctrl-H to try to figure out what control was used but failed. I also tried to use "Edit\Customize Control" to determine that control, still could not find it.
Please advise how can I figure out what kind of controls were used in some existed VI. Thanks,
RY

The name of the control is its label. It may have an empty label, meaning no name. It's also possible its label is invisible. Right click it and go to Visible Items to find out.
As for the type, the color and shape of the icon is usually the best way to tell.
Right click the diagram terminal of the control and select View as Icon. This might help you. If it doesn't, I suggest you post the 2 controls in an empty VI, and I'm sure someone can figure it out.

"Who ran me" - how to determine the name of the dbms_scheduler job that ran me

Hi Community
I can see plenty of examples out on the interweb which shows how you can use dbms_utility.format_call_stack to find the hierarchy of procs, functions and packages that got me to a particular point in my code.
For example, if proc (procedure) A calls proc B, which in turn calls proc C, in the code for proc C, I can query the call stack to find out that proc C was called by proc B which in turn was called by proc A
However, I want to extend this further.
For example, using the example above, if proc A in turn was started by a dbms_scheduler job, I want to determine (within proc C) the name of the dbms_scheduler job which started the whole process off.
The reason I want to do this is that I have inherited a (massive) system which is undocumented. In many places within the code, email alerts are sent out using a custom "MAIL" package to designated users (now including me) when certain long-running processes reach certain milestones and/or complete.
I have added to the custom "MAIL" package a trailer on the mails to show the call stack. I also want to show the name of the dbms_scheduler job which started it all.
Over time, this info may help me in building the "map" of how the whole undocumented system hangs together and in the meantime, to assist in troubleshooting problems
Looking forward to hearing from you
Alan

Use USER_SCHEDULER_RUNNING_JOBS or DBA_SCHEDULER_RUNNING_JOBS there is column SESSION_ID and when you know your session ID build query is very simple.
select owner, job_name
into ...
from dba_scheduler_runnig_jobs
where session_id=sys_context('USERENV','SESSIONID');
You must declare local variables in PL/SQL procedure to read owner and job_name into them. Second thing, you must handle possible exception no_data_found than can be raised when procedure is not run from job.

How to compare the names and types columns of two tables?

Assume I have two tables aaa and bbb
How do I compare the columnnames and types of the two columns?
It should not matter if one of them has e.g. an additional index.
Furthermore it does not matter if the rows/row values differ.

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
}Regards

EEWB : how to determine the business object and the extension type ?

Hi,
I ask myself how to determine the business object and the extension type to use to add new fields in a new tab of a specific transaction ? what means each business object, does that correspond to a specific transaction ?
I need to add a new tab in the BaMI business activity in transaction CRMD_ORDER just after the tab 'Actions' at header level.
Could you help me please to determine which business object and extension type I have to select during creation of the project and which business object category I have to select during creation of the extension (wizard) ?
Thanks for your help,
Marie

Marie,
In order to determine what type of transaction you are extending, you will need to look at the customizing for the transaction.
In the IMG:
Goto:
Customer Relationship Management->Transactions->Basic Settings->Define Transaction Types.
You will then choose the transaction defined that you want to extend. If you display the details of the transaction you will find an attribute called:
"Leading Transaction Category". This tells you the general context in which the transaction is used. The other item to view is the assignment of business transaction categories found in the maintenance screen.
This information general corresponds to one of the options that the EEWB will give you on the transaction type.
As far as extensions go, my recommendation is the following:
- Use CUSTOMER_H Customer Header Extensions for any new fields at the header level.
- Use CUSTOMER_I Customer Item Extensions for any new fields at the item level.
Unless you have a specific requirement to extend a segment of the transaction, I recommend placing all new fields in these segments. The CUSTOMER_H & CUSTOMER_I segments are considered "standard" segments, that are already built into all the necessary API structures.
Let me know if you have any further questions.
Good luck,
Stephen

How to determine the schema name from stored function or procedure

Hi all
I need to find the way to determine the name of shema in which the given stored procedure residing. This SP is created with AUTHID CURRENT_USER what means that expression like SYS_CONTEXT('USERENV','CURRENT_USER') or SYS_CONTEXT('USERENV','CURRENT_SCHEMA') will be return the name of user or schema of user which calls given SP.
can somebody help me?

What is the problem you are trying to solve?
Presumably, when you're creating a stored procedure, you know what schema owns it. So it's pretty trivial to simply create a local variable L_OWNER in your procedure, assign it the value of the schema owner, and then use that owner. Most people don't really need to figure out at runtime what they already knew at compile time.
Barring that, you could inspect the data dictionary as user130038 suggested. That requires that you know the name of the procedure (which would likely also have to be a local variable that is initialized to a hard-coded value. And if there are multiple users that own procedures with the same name, it may not be reliable.
Inspecting the call stack is the most reliable and dynamic approach. But it is also the most costly in terms or runtime performance and in terms of code complexity.

Tablespace allocation type system how oracle determines the extent size

HI
It may be silly question but the I have to ask and get some knowdge
Suppose tablespace allocation_type is system then how oracle determins the inital extent and max extent size?

Was this tablespace converted to locally managed from an existing tablespace? If so, the existing extents still exist after the conversion. Also depending on the Oracle version and maybe platform the pct_increase parameter is still honored after the conversion which can lead to odd sizes. The current value of this parameter may not be the value that was in effect when extents were allocated.
Also Oracle enhanced the logic to not leave odd sized extents unused so that if by rights the system should take a 64K extent but there is a 56K extent available (perhaps at the end of a file) it can be used to fill the extent request.

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 change the "name of column" property of an text item in runtime?

How to change the "name of column" property of an text item in runtime?
I look the properties of items in help and found nothing about this!
It's possible?

Hi,
an other solution is change the block property QUERY_DATA_SOURCE_TYPE from "Table" to "Sub-query" , than change at run time the property QUERY_DATA_SOURCE_NAME.
First create block and add items
The QUERY_DATA_SOURCE_NAME will be for ex. "Select 'A' as col1, 'B' AS col2, 'C' as col3 from dual"
Set into items the column name property to col1 , col2 ...
At run time change the query to "Select 'Z' as col1, 'X' as col2 , 'Y' as col3 from dual"
in this way you can change the source of column value.
Caution because if you change value type from varchar2 to date you must cast date into varchar2.
May be that this way is valid only for view data not for insert-update, i don't remember.
bye

How to get the name of the current tab.

Hi Experts,
I have two tabs in my tab strip and a button common to both the tabs.Can you please let me know how to get the name of the current tab in the event method of the push button.
Thanks in advance.
Regards,
Arun

1.Declare an Action for OnSelect event of Tabstrip. This event is triggered whenever any change in tab occurs.
2. Declare an Import Parameter in this method
   Tab type String.
3. This parameter has value of the selected TAB.
4. You can set this value in some Attribute in Attribute Tab in this event only (OnSelect):
     wd_this->Att = Tab.
Att is the attribute created by you in Attributes Tab of View. ( of type String)
5. Now the selected Tab ID is stored in this Attribute Att.
6. In the Onaction of Button , retrieve the selected tab value from this attribute using :
           Data : lv type string.
            lv = wd_this->Att
Now lv has your selected TAB ID.
I hope it would help you.

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 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 access the Custom Data type variable given in Expression edit control To and From LabVIEW

Hello, I would like to know how to access the custom data type variable given in the Espression Edit Control from LabVIEW and vice-versa
Say, the FileGlobals.Reference_Handle (Custom Data Type Variable) contains the
VISA I/O session (Which in turn contains VISA_DeviceName: String, Session: Number),
Channel1: Number and
Channel2: Number
I am expecting the user to give FileGlobals.Reference_Handle as the input at the ExpressionEdit Control in the edit screen of the VI Call.
I would like to know how to get the values of this custom data type to LabVIEW?
Say, if I have the Cluster in LabVIEW like VISA I/O session (Deive Name and Session Number), Channel1 and Channel2
how do i need to set this cluster to the Custom Data type variable in TestStand?
Thanks and Regards
Prakash

Hi,
TestStand to LabVIEW: i didnt understand what you r trying to achieve. But if you are using references, Use Property nodes and Invoke nodes to achieve what you want in LabVIEW.
LabVIEW to TestStand: check the image below: You need to click the button next to 'container'. I have used a cluster output in the VI.
Hope this helps
