Calling virtual function recursively

Hello,
I have a virtual function foo() in class A which, under certain conditions, will call itself.
In a class B, which is derived from A, I am overriding foo() to call super.foo() and then execute come code.
My question is:
When the code in class A executes, the recursive call this.foo() will call the function in class B (because I am in a class B object), no?
If it does, what syntax can I use to make it call the function in the context of class A, although the code is running in an object of class B?
Thank you.

Yes, and the obvious solution is to move the implementation in A out to a private recursive method foo_inner() and get A.foo() to just call foo_inner().

Calling pipelined function recursively

Hi,
I want to call Z_Get_Subprojects1 function recursively so that i get the childs for all the levels.
please tell is my approach correct.
SELECT *
FROM TABLE (Z_Get_Subprojects1(5060097))
it is giving me only level one projects.
CREATE OR REPLACE FUNCTION Z_Get_Subprojects1 (Prog_id IN NUMBER)
RETURN Ref_Pkg.abc1 pipelined
IS
CURSOR Cur(progid NUMBER)
IS
SELECT
d.ID CHILD_ID, d.UNIQUE_NAME CHILD_UNIQUE_NAME,d.is_program flag
FROM
srm_projects a,
prTask b,
prSubProject c,
srm_projects d
WHERE
a.id = b.prProjectID
AND b.prID = c.prTaskID
AND c.PRREFPROJECTID=d.id
AND a.id=progid
r_ytd_costs abc%ROWTYPE;
BEGIN
FOR c IN cur( Prog_id)
LOOP
r_ytd_costs.childid := c.child_id ;
PIPE ROW(r_ytd_costs) ;
SELECT childid INTO temp1
FROM TABLE (Z_Get_Subprojects1(c.child_id));
END LOOP;
RETURN ;
END;
/

yes i agree that we can use connect by but i need to stop at a point where a project is not a program.
whether a project is a program or not is obtained by a field is_program of srm_projects table.
i tried to use the query below using connect by but got incorrect results.
please check if i am using it correctly.
SELECT a.id parent_id,a.name,a.unique_name,d.id child_id,d.name,d.unique_name FROM
SRM_PROJECTS a,
PRTASK b,
PRSUBPROJECT c,
SRM_PROJECTS d
WHERE
a.id = b.prProjectID
AND b.prID = c.prTaskID
AND c.PRREFPROJECTID=d.id
START WITH a.id IN (SELECT id FROM SRM_PROJECTS WHERE is_program=1
MINUS
SELECT PRREFPROJECTID FROM PRSUBPROJECT)
CONNECT BY PRIOR d.id=a.id
ORDER BY a.name

Problems calling virtual functions

Hi,
     We have code running in a shared library that appears to be incorrectly changing registers that contain function parameters before the called (virtual) function acceses the registers containing its parameters.
Has anyone seen a similar problem ? If so does
anyone knaw what the solution is ?

%rcx - fourth argument - expr2_converted
%r8 - fifth argument - reln

     %rcx and %r8 are being setup correctly by the calling function but they are changed by the code that is executed by the call psudo-op that
calculates that virtual function address.

Application Class Loader problem calling virtual function

Hello everyone
I have run in to very strange behavior of JVM
I have created a class loader which allows my to load classes from
jar file, regardless that URLClassLoader supplies this functionality.
I am using this class loader to load some classes and call their virtual functions. The class diagram looks like that:
public interface I {
   public void init();
public class AAA implements
   public void init(){
public class BBB extends AAA{
   public void init(){
      //here comes implementation
}Interface I and class AAA are loaded with System Class loader and Class BBB is loaded using my class loader from jar file.
ByteStreamClassLoader classLoader = new ByteStreamClassLoader ();
Class cl = classLoader. loadClass(�com.product.BBB�,true);
I myInterface = cl.newInstance();
myInterface.init();The problem is that from some unknown reason java class AAA.init() instead of BBB.init().
Can somebody help me what am I doing wrong?
Class Loader code attached below
public class ByteStreamClassLoader   extends ClassLoader {
    protected HashMap m_cache = new HashMap();
    public void clearCashe() {
      m_cache = new HashMap();
    private String definePackage(String className) {
      StringBuilder strB = new StringBuilder();
      //Class name must be removed from the URI in order to define a package
      String[] packageArray = className.split("\\.");
      for (int i = 0; i < packageArray.length - 1; i++) {
        strB.append(packageArray).append(".");
String packageName = strB.toString();
packageName = packageName.substring(0, packageName.length() - 1);
if (getPackage(packageName) == null) {
m_logger.log(Level.FINEST, "Defining package '" + packageName + "'");
definePackage(packageName, null, null, null, null, null, null, null);
return packageName;
public synchronized Class loadClass(String name, boolean resolve) throws

name = name.replaceAll("/", ".").replaceAll(".class", "");
//Try to locate the Class in cashe

Hello everyone
I have run in to very strange behavior of JVM
I have created a class loader which allows my to load classes from
jar file, regardless that URLClassLoader supplies this functionality.
I am using this class loader to load some classes and call their virtual functions. The class diagram looks like that:
public interface I {
   public void init();
public class AAA implements
   public void init(){
public class BBB extends AAA{
   public void init(){
      //here comes implementation
}Interface I and class AAA are loaded with System Class loader and Class BBB is loaded using my class loader from jar file.
ByteStreamClassLoader classLoader = new ByteStreamClassLoader ();
Class cl = classLoader. loadClass(�com.product.BBB�,true);
I myInterface = cl.newInstance();
myInterface.init();The problem is that from some unknown reason java class AAA.init() instead of BBB.init().
Can somebody help me what am I doing wrong?
Class Loader code attached below
public class ByteStreamClassLoader   extends ClassLoader {
    protected HashMap m_cache = new HashMap();
    public void clearCashe() {
      m_cache = new HashMap();
    private String definePackage(String className) {
      StringBuilder strB = new StringBuilder();
      //Class name must be removed from the URI in order to define a package
      String[] packageArray = className.split("\\.");
      for (int i = 0; i < packageArray.length - 1; i++) {
        strB.append(packageArray).append(".");
String packageName = strB.toString();
packageName = packageName.substring(0, packageName.length() - 1);
if (getPackage(packageName) == null) {
m_logger.log(Level.FINEST, "Defining package '" + packageName + "'");
definePackage(packageName, null, null, null, null, null, null, null);
return packageName;
public synchronized Class loadClass(String name, boolean resolve) throws
ClassNotFoundException {
name = name.replaceAll("/", ".").replaceAll(".class", "");
//Try to locate the Class in cashe
Class c = (Class) m_cache.get(name);
//Try to locate the Class in the System Class Loader
if (c == null) {
try {
c = ClassLoader.getSystemClassLoader().loadClass(name);
catch (Exception ex) {}
else {
m_logger.log(Level.FINEST, "Class '" + name + "' found in cache");
//Load the class from byte array
if (c == null) {
String resourceName = name;
if (!resourceName.endsWith(".class")) {
resourceName = resourceName.concat(".class");
//Retrieve class byte representation
if (resourceName.indexOf(".") != -1) {
resourceName =
resourceName.replaceAll("\\.", "/").replaceAll("/class", ".class");
//Use the ByteStreamClassLoader to load the class from byte array

HT203175 I have no problem signing on to iTunes my issue is once on the site I can not use the "search". It says there is a runtime error R6025 pure virtual function call. Has anyone had this problem and how do I fix it. Thanks

I do not have a problem getting in the iTunes stores. My issue is once on the site I can not use the "search". It says there is a pure virtual function call R6025. How can I solve this problem? Do I have to create a new account? Do I have to uninstall and re-install? Thanks

Thanks so much for your feedback. I really appreciate any input here.
If someone from Adobe could GUARANTEE that this problem would go away if I
purchased CS4, I would pony up the cash and do it. However, I'm skeptical
about that because I just saw someone else post a message on the forum today
who is running CS4 and getting the exact same runtime error as me.
I'll try un-installing and re-installing as Admin, and if that doesn't work,
maybe I can find a used copy of CS3.
In the meantime, I'm also wondering if a Photoshop file can carry any sort
of corrupt metadata inside it once it has errored out? Reason I ask is, I
had to port all of my old PSD files to the new computer, and I only seem to
be getting this error when I attempt to work on one of the files that
previously got the runtime error when they were sitting on my XP machine.
When I create new files from scratch on this new computer, they seem to be
working just fine (at least, for now).
If so, I would probably be smart to never open those troublesome
"errored-out" files again.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

"R6025 -pure virtual function call" Error While Use Adobe Media Encoder

I'm trying to use Adobe Media Encoder (CS3) to output a project to H.264. I have about 3 minutes of footage on the Premier Pro CS3 Timeline, all of it in Cineform AVI intermediate format. When I export the movie through AME and select 2-pass VBR, it gets through the first pass, but crashes at 50% on the second pass with the error:
"Microsoft Visual C++ Runtime Library
Runtime Error!
Program E:\Progra...
R6025
-pure virtual function call"
Any ideas what may be causing this error?

Point taken...
I'm on a Dell XPS 720 Windows XP (32-bit) system, with all up-to-date service packs and patches. I have 4GB RAM installed, and Production Premium CS3, TMPGEncXPress and Cineform's Neo Scene. Neo Scene is a recent addition and the problem existed prior to its installation. I have two 7900GS graphics cards (each with 256MB video RAM), running in SLI mode.
I dual boot Windows XP: One system is "Messy" with all kinds of stuff installed. The other is "Clean" and has virtually nothing installed, except for the three suites previously mentioned. No anti-virus or anti-spyware software is installed on the Clean system. I get the error on both systems.
I saw the post from September 2007 reference vcredist_x86. I'll be trying that at my next opportunity, however, I'm not sure that will fix it, as I don't see why both systems would suffer from the same corruption. I'll also be swapping out RAM to see if that fixes the issue.

I can't search a song or an artist. i get an error R6025/pure virtual function call. then itunes stops working. PLEASE HELP

I can't search a song or an artist without getting an error R6025 - pure virtual function call. Then itunes stops working. How do I fix it? PLEASE HELP

I have had numerous issues with Itunes 64 bit 11.1.38 (and other previous versions) locking up and crashing upon start with "Itunes has stopped working" or "R6027 pure virtual function call". I have researched the answers around the forums as well as having tried some extensive and repetitious troubleshooting myself and thought I'd list them here... in order of troubleshooting...
1. Install all Windows updates and reboot. This seems to clear issues from time-to-time... I suspect Itunes expects the latest-and-greatest as far as Windows is concerned.. see if this clears your issue.
2. Uninstall all Itunes and Apple products & reboot, remove their directories, remove lingering Itunes registry entries, reboot again, reinstall using "RUN AS ADMINISTRATOR" to install the Itunes executable. See if this allows Itunes to stabilize. Pelase be sure to use the following guide from Apple as far as removing the apps and directories are concerned...
http://support.apple.com/kb/ht1923
3. Remove the contents of the "iphone photo cache" (or other related product photo cache) directory.
4. Try editing the shortcut properties and configure the shortcut (for all users) to run as Administrator.
5. Try editing the shortcut and configure it to run in Compatibility Mode for Windows 7 (for all users).
6. a.Try using MSCONFIG to locate a potential conflicting application or service using the following...
http://support.apple.com/kb/ht2292
or
6. b. Remove the last recent software application(s) you may have installed... in my case removing GREENSHOT http://getgreenshot.org/ stopped my Itunes from crashing on startup and it stabilized after
driving my nuts for weeks.

I work usually with large PDF documents, and I was trying to convert a PDF document of 1000 pages ONE THOUSAND PAGES, to little PDF documents of 10 MB each one.
When I tried to convert the PDF file into little ones, craaashhhhhhhhhhhhhhhhhh
I got this message:

Recursive call of function module 'CRM_ORDER_MAINTAIN'

Hi together,
I have got the follwoing problem.
We have to implement a proof on a partner function regarding the role.
I found the BADI IF_EX_COM_PARTNER_BADI~COM_PARTNER_CHECK
I implement the the follwoing coding:
IF is_partner_wrk-partner_fct = 'ZADI0012'.
    SELECT SINGLE * INTO ls_but100
                    FROM but100
                    WHERE partner = is_partner_wrk-external_partner_number
                    AND   rltyp   = 'BUP004'.
    IF sy-subrc = 4.
      MESSAGE e003(crm_ic_partner) WITH is_partner_wrk-external_partner_number.
    ENDIF.
ENDIF.
when I enter a partner with a wrong role, I got the message I have implemented. Afterwards I type in a partner with the correct role I got a short dump.

Has anybody an idea how to solve this issue?

Intermittent Runtime error - pure virtual function call

I have an intermittent runtime error - pure virtual function call & don't know what cause it? Since It only occurs & crashes once awhile therefore it's difficult to trap it for debugging.I suspect it come from TestStand ActiveX API which I use in my User Interface Application project but I'm not really sure.
Does anyone experience this kind of problem when working with TestStand API ? If so any
suggestion? I have noticed in the TestStand API header file teapi.tlh contain many raw_.... function defined as pure virtual function. What are these raw_... function ? I don't think I use any of these function in my project.
Many thanks!

Danh,
I don't believe that your problem can be solved with the information you have provided unless someone else has experienced the same symtpoms which coincidentally have the same cause as in your case.
Is there any other information you can provide that can help localize the problem?
1) What is happening when the error occurs?
2) Does the error always occur in the same place?
3) Does it always occur with use of certain resources (e.g. DAQ, GPIB, VISA, printer)?
4) Does it occur when using the sequence editor?
5) Does it occur when using one of the shipping operator interfaces?
6) Does it occur only when using your operator interfaces?
7)Is it related to a specific sequence or any sequence?
8) Does it happen when you executed your sequence with/without a process model entr
y point (i.e. Execute>>Test UUTs, Execute>>Singal Pass or Execute>>Run MainSequence)?
9) How often does it happen?
10) What version of TestStand are you using?
11) With what language (include versions) are you programming your code modules?
12) With what language (include versions) are you programming your operator interface?
13) Is there any error code reported with this error message?
14) Is this error reported in a TS run-time error dialog or is it reported directly 1by the operating system?
15) Have you searched the web for related errors? For example, the following link describes a particular programming mistake that can lead to this error
http://support.microsoft.com/support/kb/articles/Q125/7/49.asp
By investigating answers to the above questions you may be able to narrow the cause of this error, which might allow you or others to help solve the problem.

R 6025 pure virtual Function Call

Hello, I'm having trouble with my Premiere elemnts 12, to start the message - R 6025 pure virtual Function Call - Exception Unknown Software Exception (0x400000015) in 0x78b2d6fd. My system is XP pac 3. I tried to find the solution but I found .Agradeço who can guide me, thanks.

I bought the license in January / 2014 package with Adobe Premiere / Photoshop Elements, and sent me for download. Was functioning normally and is only now that had this error. My XP SP3 32-bit Pentium Dual Core E 6500 2.93 GHz, 2 GB RAM and 300 GB of free space. The original anti virus is Kaspersky Internet Security and have the latest version of Quick Time. I have made many times the procedure to uninstall - CCleanner - reinstall. I do not understand "let us try creating a new User Account with Administrative Privileges and installing and running Premiere Elements 12 / 12.1 from this new account." Thank you.
