Hi Anirban,
The function module always return a class_not_defined exception.
Is there anything wrong when loading this?

I cannot find a method or property in ACEDAO to retrieve the precision and scale of a field. Maybe you could try get the number of a decimal type and use some mathematical methods to get the precision.
I find there are some way to get the precision by ADO or OLEDB.
For ADO way, you could check this thread:
https://social.msdn.microsoft.com/Forums/office/en-US/883087ba-2c25-4571-bd3c-706061466a11/how-can-i-programmatically-access-scale-property-of-a-decimal-data-type-field?forum=accessdev
For OLE DB , you could use IColumnsInfo::GetColumnInfo to get DBCOLUMNINFO::bPrecision.
https://msdn.microsoft.com/en-us/library/windows/desktop/ms722704(v=vs.85).aspx
Also people in C++ may not familiar with access development, the
Access for Developers forum is good place for access develop issue. You could try there.
Hope this helps some.

my friend gave me ipod touch with all his accounts, i created new accounts but when i went on the appstore and tried to update apps installed by him,i was asked his account's password! i dont know his password.how can i use my account to update apps?

You can't. Apps and really all content purchased/downloaded through one Apple ID is forever tied to that Apple ID. In the case of Apps they will always request that Apple ID to update as they are licensed to that Apple ID.
In reality, the Apps were licensed to that Apple ID by the developer. And cannot simply be given away to you for you to use.
He should have wiped the iPod clean so you could set it up for your use without any of his accounts or purchased content as you are not really licensed to any of those Apps.
Your friend should have followed this support document before giving the iPod to you:

It sounds like you are talking about the cloning tool?
Tool looks like this:
Then when selected you can change the size of the brush and using Alt (windows) and Command (Mac) to select your region you want to copy then start to create you cloned image.
Hope this helps?

My iphone 4s is 2nd ...then i format..the phone want old user id...how can i used that iphone back because i dont know the id?

There is no other solution - as you have already been told, if you don't have that user id and you cannot contact the previous owner of that id for the phone, then there is absolutely nothing that you can do. You have a useless brick that you can't use.
Nothing else to do.

If you absolutely must have the Microsoft applications, you can purchase and download them from http://microsoft.com/mac.
Free software suites LibreOffice and OpenOffice offer similar functionality (word processing and spreadsheets).
Or you could do worse than look at Apple's Pages, Numbers and Keynote, which should already be installed in your Mac and can export to Microsoft formats if need be.

How can we use cl_gui_html_viewer      in a background process.

Hello,
Refering to this thread: Pie chart using Class cl_igs_chart ??
How can we use cl_gui_html_viewer     in a background process.
I want to execute a html code in bakground process in abap program.
but using cl_gui_html_viewer   I have an error with CNTL_ERROR in the method CONSTRUCTOR;
Thanks

Marie,
I don't know about HTML viewer specifically, but whenever a GUI object is needed to be used in background, there is a standard method to avoid CNTL_ERROR.
When a program runs in background, there is no "screen" and hence no GUI, and hence a custom control can not be displayed. That is why the program generates an error.
The trick is to avoid creating the custom control in background.
if sy-batch = 'X'. "background mode
*   We don't want to create the custom control
else. "dialog mode
    create object l_container exporting ...
endif.
* We really don't need a container for using CL_GUI_ objects
* Proceed with the normal coding
create object l_html_viewer
exporting
    parent = l_container

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

How can I use multiple row insert or update into DB in JSP?

Hi all,
pls help for my question.
"How can I use multiple rows insert or update into DB in JSP?"
I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
With thanks,

That isn't true. Different SQL databases have
different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
and there are also a lot of different ways of talking to
SQL databases that are possible in JSP, from using
plain old java.sql.* in scriptlets to using the
jstlsql taglib. I've done maintenance on both, and
they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
Well, sure. As long as you only want to update rows
with the same value in column 2. I had the impression
he wanted to update a whole table. If he only meant
update all rows with the same value in a given column
with the same value, that's trivial. All updates do
that. But as far as I know there's know way to update
more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
Unless you're using MySQL, for instance. I only have
experience with MySQL and M$ SQL Server, so I don't
know what PostgreSQL, Oracle, Sybase, DB2 and all the
rest are capable of, but I know for sure that MySQL
can insert multiple rows while SQL Server can't (or at
least I've never seen the syntax for doing it if it
does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
Don't assume that all SQL databases are the same.
They're not, and it can really screw you up badly if
you assume you can deploy a project you've developed
with one database in an environment where you have to
use a different one. Even different versions of the
same database can have huge differences. I recommend
you get a copy of the O'Reilly book, SQL in a
Nutshell. It covers the most common DBMSes and does a
good job of pointing out the differences.Yes, I understand that.
It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

How can i use or embed the ' C' language in java

thanks a lot friends for your suggestion on using 'c' language to implement the control of the keyboard ie. to prevent a key stroke of : ctrl+alt+delete keys from closing a running java application. i was advised that it won't be possible to implement this with java language, the use of 'C' language was suggested. i then wish to ask the following:
1. how can i use 'C'language in a java program and be able to compile to program so that the resultant program can help me prevent the closing of my java-application when the user of the application presses the following keys : ctrl+alt+delete. i don't even know the c language at all. how can i start and how can i combine the resultant code with java.
2. i'm thinking of creating an application that retrieves information from a database, like microsoft sql or oracle, and displays the resultant data from a table, say STUDENT TABLE, in a java application using the JTable class. i don't even know how to use this JTable but i've seen it used and know it will suit what i have in mind.
3. how can i make the table dynamic, ie. how can i make the table to immediately register / show the result of an update to the 'STUDENT' table in the database.
4. THANKS FOR YOUR HELP IN ADVANCE. i will most appreciate it if you can give me a sample code or a site where i download one. once again thanks.

Good luck disabling Ctrl+Alt+Del! I've read quite a bit about it, and at least on Windows 2000 (not sure about NT) or higher, disabling it is next to impossible. Problem is CAD is a system command, and the OS doesn't even send the keys to the active program. Ctrl+Alt+Del is handled by the GINA (Graphical Identification and Authentication) DLL installed on the system. You'll have to write and export the functions you need and change the GINA DLL used by the system to your own. Bear in mind that any small mistake in the dll can cause you to lose access to your computer if you haven't taken precautions!
On Windows 95/98, disabling Ctrl+Alt+Del is fairly easy as you just have to write some simple native code to fool the system that a password protected screensaver is running.
I've provided a link regarding winlogon and GINA here, but you've been forewarned!

How can I use my array in another method.... Or better yet, what's wrong?

I guess I'll show you what I am trying to do rather and then explain it
public class arraycalc
int[] dog;
public void arraycalc()
dog = new int[2];
public void setSize(int size)
dog[1] = size;
public int getSize()
return dog[1];
This gives me a null pointer exception...
How can I use my array from other methods?

You have to make the array static. :)
Although I must admit, this is rather bad usage. What you want to do is use an object constructor to make this class an object type, and then create the array in your main class using this type, and then call the methods from this class to modify your array. Creating the array inside the other method leads to a whole bunch of other stuff that's ... well, bad. :)
Another thing: Because you're creating your array inside this class and you want to call your array from another class, you need to make the array static; to make it static, you must make your methods static. And according to my most ingenious computer science teacher, STATIC METHODS SUCK. :D
So, if you want to stick with your layout, it would look like:
public class arraycalc
     static int[] dog;
     public static void arraycalc()
          dog = new int[2];
     public static void setSize(int size)
          dog[1] = size;
     public static int getSize()
          return dog[1];
}But I must warn you, that is absolutely horrible code, and you shouldn't use it. In fact, I don't even know why I posted it.
You should definitely read up on OOP, as this problem would be better solved by creating a new object type.

How can we use mode "UsePDF" in Interactive form?

Hello everybody,
I want to know that how can i use the mode usePdf in Interactive form?
My scenario is:
I have pdf form saved locally with blank fields.
I save this file after requied values in all fields.
Now i want to import this pdf file in interactive form and needs to submit this form so all the data in this pdf file are submitted to the System.
How can i do this?
regards,
Bhavik

Hi Bhavik,
you do not need to use the upload ui element, if your pdf-file which you want to upload resides in you web application project. In the following you can find Web Dynpro code snippets I use in one of my demos for displaying an uploaded pdf-file:
wdDoModifyView method of FormView:
    //@@begin wdDoModifyView
     try {
          // get interactive form element by ID
          InteractiveForm form = (InteractiveForm) view.getElement("Evaluation");
          if (wdContext.currentContextElement().getCurrentMode().equals("usePDF")) {
               form.setMode(WDInteractiveFormMode.USE_PDF);
     catch (Exception e) {
          e.printStackTrace();
    //@@end
onPlugFromUploadView method of UploadView:
    //@@begin onPlugFromUploadView(ServerEvent)
     try {
          // modify the context and set needed attributes
          wdContext.currentContextElement().setCurrentMode( "usePDF" );
          // extend the attribute "pdfSource" from the context to a modifiable binary type
          IWDAttributeInfo attInfo = wdContext.currentContextElement().node().getNodeInfo().getAttribute("pdfSource");
          ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();
          IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;
          binaryType.setFileName("evaluationForm.pdf");
          binaryType.setMimeType(WDWebResourceType.PDF);
          // add the generated pdf to the context
          wdContext.currentContextElement().setPdfSource( evaluationForm ); // byte[] evaluationForm
     catch (Exception e) {
          wdComponentAPI.getMessageManager().reportWarning(e.getLocalizedMessage());
    //@@end
If you do not want to display the data before submitting the data, then you have to use the WDInteractiveFormHelper class for extracting the form data after upload in the context. This class is available since NetWeaver04 Support Package Stack (SPS) 10. The class com.sap.tc.webdynpro.clientserver.adobe.api.WDInteractiveFormHelper contains at the moment one helper function for PDF document. Here are the details:
Constructor Detail
public WDInteractiveFormHelper()
Method Detail
public static void transferPDFDataIntoContext(byte[] pdfSource, IWDNode targetNode)
Method transferPDFDataIntoContext extracts data from a PDF document and copies the values into the Web Dynpro Context. The xml structure of the document data is applied starting from the specified target node. Usually, this node should be the same context node to which InteractiveForm-UIELement property dataSource is bound during PDF generation.
Parameters:
pdfSource - PDF document as byte[]
targetNode - target IWDNode
Hope this will help you,
Regards, Carsten

How can I using functions implicit in dll file in java code ?

How can I using functions implicit in dll file in java code ?
I'm developing a program that interfacing with fingerprint hardware.
I have the finger print already, and I have to the SDK that have all functions for managing this fingerprint.
These SDK functions are represented in dll files.
I want to know how can I use these functions in java code .
I looked on this link of sun forums :
http://forum.java.sun.com/thread.jspa?threadID=305171&messageID=1215613
but I don't Understand the meaning of native code.
Thanks for help.

please please please please please please please please help me:
After reading a lot of articles, tutorials, and overviews about JNI (Java Native Interface)
I found that these steps
1.     Develop the Java code
2.     Compile the Java code to a class file
3.     Generate the header file
4.     Implement the native method
5.     Create the shared library or DLL
6.     Run the Java program
Is the common steps in JNI development
The most powerful link was
http://java.sun.com/docs/books/jni/html/start.html
and
http://www.netbeans.org/kb/55/beginning-jni-part2.html
and the pdf oh this link
http://www.ibm.com/developerworks/edu/j-dw-javajni-i.html requiring IBM registration to download it.
But I have already the DLL, and want to the stright forward way to use its functions by java code only.
I don not to write any C++ code .
Is this possible???????????????????????????????

Please,how can I use javamail to implementing draft box on webmail

please,how can I use javamail to implementing draft box on webmail

I already can send and receive EMail ��create
subfolder with javamail in imap server.but I don't
know how implement draft mailbox with webmail .
please expert help me . thanksyou can only create subfolders in a imap mail server ,and you can use folder class included in javamail api to access,create,modify and delete subfolders.You also can create subfolders under a subfolder as you want.
the simple example is:
//first create mail session
mailSession=...
// second create mail store
mailStore=...
//third get root folder
IMAPFolder rootFolder = (IMAPFolder)mailStore.getFolder("INBOX");
if ((rootFolder==null)||(!rootFolder.exists())) return false;
//finally create a subfolder "outbox" under root folder "inbox"
IMAPFolder tmpOutFolder = (IMAPFolder)rootFolder.getFolder("OUTBOX");
if (tmpOutFolder==null) return false;
//if the target folder not exist just create it
//note:when you create a subfolder you can assign its attribute.Details,please read the javamail document.
if(!tmpOutFolder.exists()) tmpOutFolder.create(Folder.HOLDS_MESSAGES);

How can I know a parent class of a certain class? which FM can be used?
