How do I read the metadata of an object in abap?
I need to find a way to read the metadata of an object (say an internal table) in abap. An example of what I am looking to do is that I want to get a list of all the column names of an internal table. Any help would be greatly appreciated!

Sure, use this function.
TYPES: BEGIN OF type_item,
f1 TYPE char30,
f2 TYPE char30,
f3 TYPE char30,
f4 TYPE char30,
END OF type_item.
DATA: lineitems TYPE TABLE OF type_item WITH HEADER LINE,
fieldlist TYPE TABLE OF rstrucinfo WITH HEADER LINE.
DATA: syrepid TYPE sy-repid.
syrepid = sy-repid.
* gets all of the components of a structure
CALL FUNCTION 'GET_COMPONENT_LIST'
EXPORTING
program = syrepid
fieldname = 'lineitems'
TABLES
components = fieldlist.
LOOP AT fieldlist.
WRITE:/ fieldlist-compname .
ENDLOOP.

How do I read table metadata?
Hi
Can anyone advise me how to read the metadata in through a JDBC connection?
Specifically I am connecting to a DB2 database and reading in the table names for a given schema from the table: -
// Connect to DB and read in the table names
stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT NAME FROM SYSTOOLS.HMON_ATM_INFO WHERE SCHEMA = '" + schema + "'");
while(rs.next()){
tblNames.add(rs.getString("NAME"));
Now I want to iterate through my ArrayList tblNames and use each table name to query each table's metadata, specifically the name of each field in the table and its datatype and size. Is it possible to do this through the getMetaData call something like this: -
// Got the table names so read the table metrics
Iterator<?> tnms = tblNames.iterator();
while(tnms.hasNext()){
String[] types = {"NAME"};
String tableName = (String)tnms.next();
DatabaseMetaData dbmd = conn.getMetaData();
rs = dbmd.getTables("", schema, tableName, types);
Thanks in advance

How can I read the bootstrap files of any HDS Live stream and extract the fragment-URLs and fragment-numbers in plain text?
Could it be that it is some kind of compressed format in the bootstrap? Can I uncompress it wirh f4fpackager.exe? Could not find any download for f4fpackager.exe. I would prefere less code to do so. Is there something in Java of JavaScript, that can extract the fragment-numbers?
Thank you!Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave. -
Hello! I am trying to develop an application in C++ for measurements with Agilent(HP) 8510C network analyser using NI488.2 and National Instrument's PCI-GPIB card. In HPBASIC the trace data is read using OUTPDATA command which contains PREAMBLE, SIZE and then the data string in real and imaginary pair for the required points. The ibrd function gives data only for one point. Kindly guide me how I can read the whole trace and and separate out the real and imaginary data values. Regards, kapil
Hey Kapil,
It seems that in HPBASIC you were using an instrument driver for the 8510C. OUTPDATA is not a native HPBASIC function. National Instrument has similar instrument drivers for LabVIEW and CVI.
http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/7b235254f3881ddb862568ab005fbd2e?OpenDocument
http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/24ca7db880ab78ae862568ab005fbc0f?OpenDocument
For example in the CVI instrument driver you will find a source file called hp8510.c. In the source code you will find a function called hp8510c_dataInRaw that sounds similar to the function that you described.
Note that this example is designed for CVI, but it is possible that you could extract the information you need for C++. If
you had a copy of CVI you could just add the files downloaded from the instrument driver to a project and then compile and run the project. It already contains a ready to run example that allows you to capture data and use your instrument.
If you want try CVI you can download an evaluation copy on-line at http://ni.com/lwcvi/launch.htm.
I hope this helps out,

How can I read the printer snapshot file printers.xml
How can I read the printer snapshot file printers.xml
XML files are typically viewed using a web browser.
Open the XML file and the default program should open it automatically. If you are prompted to select a program, use the option that lets you choose a program and brows through the directories for your browser (for example, use Internet Explorer, Firefox, etc.).
If need be, you should be able to right-click the file and select open with to choose the program to open it with.
There are other XML viewers out ther, but web browsers are typically the default as XML is a web language.

SapScript, How do I read the current line number?
I have sections of text - each in it's own element with an 'include' of the standard text.
These sections are variable in size.
All elements are in the MAIN window.
I do not want a paragraph to split over two pages.
How do I read the current line number within the sapscript before the section prints so I can issue a new-page command at the beginning of the paragraph?
Thanks!Yes, that does work for paragraphs.
If I have multiple elements to print from within a loop where "at first, at each and at last" each call the Sapscript funtcion write_form - how can I keep the whole section together. protect/endprotect will keep each element together but not the group of elements.
There must be a way to find the current line number. -

How do I read the selected value of a comboBox?
I need to send the selected value of a comboBox in an HTTPService request. How do I read the selected value (not label or item or index) from the comboBox?
> (not label or item or index)
I suspect 'item' is what you need actually. Specifically the 'selectedItem' property which returns the whole of the selected object from your dataprovider. From that you can then extract the selected object's properties.
e.g. selectedValue = myComboBox.selectedItem.value;
The example in tour-de-flex shows this - note: 'data' in that example is i think what you call 'value'.

You might be better off asking this on a MS Access forum. It's more of an Access issue than a CF one.

How can I read the trace data into LabVIEW for E5071B
HI
I am setting up the measurement using vector network analyzer (VNA) E5071B controlled by NI 488.2. How can I read the trace data into LabVIEW and display on the graph? If anyone having an idea or know well about this process please give me the suggestion, I will much appreciate it.
Many ThanksYou want to start with the driver
In case you do not know it, you can do the driver search in LabVIEW from Tools>Instrumentation>Find Instrument Drivers. You might also want to bookmark the Instrument Driver Network for information on what a driver is and how to use it. -
How can I read the image from database into form
hi everyone
if I have table like this
create table test
(id number(10),
pic long raw);
in this table record
in form If I have block non database
how can i read the image into non database item
I try with this code but no good
select pic into :photo from test where id=5;
photo its non database item kind image
how can i invoke image into item
thanks aloooooootHello,
You can't select image with select query. You need to create another database block from test table which has item binds with database pic column. Now in where condition in test block's property you have to write id=5. Change test block's properties UPDATE ALLOWED, INSERT ALLOWED, DELETE ALLOWED to NO. Only Query allowed property set to YES.
Now in your particular trigger write the code
GO_BLOCK('test');
Execute_Query;
please mark if it help you or correct

How do you read the camera position in the 3d picture control?
Hello,
There is a method to setup the camera position, but how do you read the current camera position? e.g. the user uses the mouse, ctrl, and shift, to change the camera position. How do you read this new camera position? There don't seem to be any properties to do this.
I've read this thread:
http://forums.ni.com/ni/board/message?board.id=170&message.id=214629&requireLogin=False
but the question was never answered....
From the comments in that thread, even if you had the proper documentation for the "Model Matrix" property, you couldn't get the information necessary to calculation the camera position.Lorielle,
Thanks for the VI.
Could you point me towards a more detailed description of the "Modelview Matrix" property? I've attached a screenshot from the online help. It is not very helpful.
