What is the functionality CALL METHOD CL_GUI_CFW= FLUSH

Hi,
What is the functionality of method "FLUSH" in class CL_GUI_CFW
Should it be used after every call method CL_GUI_FRONTEND_SERVICES=>......
What is the purpose of using it? What happens if we don't use it?

hi
good
The class CL_GUI_CFW contains static methods that apply to all instantiated custom controls when you call them.
You can force a synchronization point in your program by calling a method that is not buffered, or by calling the static method FLUSH.
CLASS event_handler IMPLEMENTATION.
METHOD handle_f1.
    DATA row TYPE i.

Problem with CL_GUI_CFW= DISPATCH

hi experts,
when I double click on a node , the dispatch metod :
CALL METHOD CL_GUI_CFW=>DISPATCH
IMPORTING
RETURN_CODE = RETURN_CODE.
returns ' -1'. ( RETURN_CODE = -1 ).
means no event triggered, but I have double click on the node.
Please tell me what could be the reason.
Thanks.

Cl_gui_cfw= dispatch

Hi,
CALL METHOD cl_gui_cfw=>dispatch.
I would like to know the usage of this method. pls explain in detail.
Thanks & Regards,
Kalaivani P

Main use of this method (CALL METHOD cl_gui_cfw=>dispatch ) is " to dispatch the application events to the event handler registered for events. "
If you do not call the method in PAI event, after processing of PAI it is called the events automatically and return the return_code.

Error calling methods CL_GUI_FRONTEND_SERVICES

Hi all,
I have a requirement in BAPI (integrating solman to portal) to download file from app. server to local directory. I used the below FM to get temp directory of presntation server.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_TEMP_DIRECTORY
   CHANGING
     TEMP_DIR             = LV_TEMP_DIR

     others               = 4.
   CALL METHOD cl_gui_cfw=>flush.
It works fine in R3, but when i called it from portal it shows Access not possible using 'NULL' object reference with a short dump .
st22 shows
Error in ABAP application program.
The current ABAP program "CL_GUI_FRONTEND_SERVICES======CP" had to be
terminated because one of the
statements could not be executed.
This is probably due to an error in the ABAP program.
An exception occurred. This exception is dealt with in more detail belo
. The exception, which is assigned to the class 'CX_SY_REF_IS_INITIAL',
neither
caught nor passed along using a RAISING clause, in the procedure
"GET_TEMP_DIRECTORY" "(METHOD)"
Since the caller of the procedure could not have expected this exceptio
to occur, the running program was terminated.
The reason for the exception is:
Attempt to access a component using 'NULL' object reference (points
to nothing).
An object reference must point to an object (an instance of a class)
before you can use it to access components (variable:
"CL_GUI_FRONTEND_SERVICES=>HANDLE").
Either the reference has not yet been set, or it has been reset to
'NULL' by a CLEAR statement.
When i put external break point and the dump comes during execution of CALL METHOD cl_gui_cfw=>flush.
Is it not possible to use CL_GUI_FRONTEND_SERVICES in RFC ??.
thanks and regards

the dump is because you cannot use that function from a BSP application, which runs in internet or intranet. The procedure in this case is different:

Hi,
I want to use 'CALL METHOD cl_gui_frontend_services=>file_save_dialog', to choose a path for saving my txt files. I only want the user to be able to choose the path and not have to supply a filename aswell. My filenames are standard in the program and I don't want them to be changed by the user.
Is there another method which is designed for this or is there a simple parameter I have missed?

How to call methods from within run()

Seems like this must be a common question, but I cannot for the life of me, find the appropriate topic. So apologies ahead of time if this is a repeat.
I have code like the following:
public class MainClass implements Runnable {
public static void main(String args[]) {
Thread t = new Thread(new MainClass());
t.start();
public void run() {
if (condition)
doSomethingIntensive();
else
doSomethingElseIntensive();
System.out.println("I want this to print ONLY AFTER the method call finishes, but I'm printed before either 'Intensive' method call completes.");
private void doSomethingIntensive() {
System.out.println("I'm never printed because run() ends before execution gets here.");
return;
private void doSomethingElseIntensive() {
System.out.println("I'm never printed because run() ends before execution gets here.");
return;
}Question: how do you call methods from within run() and still have it be sequential execution? It seems that a method call within run() creates a new thread just for the method. BUT, this isn't true, because the Thread.currentThread().getName() names are the same instead run() and the "intensive" methods. So, it's not like I can pause one until the method completes because they're the same thread! (I've tried this.)
So, moral of the story, is there no breaking down a thread's execution into methods? Does all your thread code have to be within the run() method, even if it's 1000 lines? Seems like this wouldn't be the case, but can't get it to work otherwise.
Thanks all!!!

I (think I) understand the basics.. what I'm confused
about is whether the methods are synced on the class
type or a class instance?The short answer is; the instance for non-static methods, and the class for static methods, although it would be more accurate to say against the instance of the Class for static methods.
The locking associated with the "sychronized" keyword is all based around an entity called a "monitor". Whenever a thread wants to enter a synchronized method or block, if it doesn't already "own" the monitor, it will try to take it. If the monitor is owned by another thread, then the current thread will block until the other thread releases the monitor. Once the synchronized block is complete, the monitor is released by the thread that owns it.
So your question boils down to; where does this monitor come from? Every instance of every Object has a monitor associated with it, and any synchronized method or synchonized block is going to take the monitor associated with the instance. The following:
synchronized void myMethod() {...is equivalent to:
void myMethod() {
    synchronized(this) {
...Keep in mind, though, that every Class has an instance too. You can call "this.getClass()" to get that instance, or you can get the instance for a specific class, say String, with "String.class". Whenever you declare a static method as synchronized, or put a synchronized block inside a static method, the monitor taken will be the one associated with the instance of the class in which the method was declared. In other words this:
public class Foo {
    synchronized static void myMethod() {...is equivalent to:
public class Foo{
    static void myMethod() {
      synchronized(Foo.class) {...The problem here is that the instance of the Foo class is being locked. If we declare a subclass of Foo, and then declare a synchronized static method in the subclass, it will lock on the subclass and not on Foo. This is OK, but you have to be aware of it. If you try to declare a static resource of some sort inside Foo, it's best to make it private instead of protected, because subclasses can't really lock on the parent class (well, at least, not without doing something ugly like "synchronized(Foo.class)", which isn't terribly maintainable).
Doing something like "synchronized(this.getClass())" is a really bad idea. Each subclass is going to take a different monitor, so you can have as many threads in your synchronized block as you have subclasses, and I can't think of a time I'd want that.
There's also another, equivalent aproach you can take, if this makes more sense to you:
static final Object lock = new Object();
void myMethod() {
    synchronized(lock) {
      // Stuff in here is synchronized against the lock's monitor
}This will take the monitor of the instance referenced by "lock". Since lock is a static variable, only one thread at a time will be able to get into myMethod(), even if the threads are calling into different instances.

Call method http_client- response- get_header_fields for PDF and for TIFF

Hi,
I am using a Function Module..

Hi Niranjan,
can you please check if you have imported the whole chain of certificates. Certificates usually diplayed in 3 levels in the Explorer. like
Verisign - L1
>>> Versign-- L2
>>>>>>>>>>>>XYZ.com -- L3
Extract all the 3 certificates and Put in Strust and do exit soft and hard in SMICM and restart the service.
Its better to create a RFC destination of Type H and Do the Connection test for HTTPS configuration. If the connection test comes OK then u can be sure of the configuration.

How to Call Methods in Ecatt?

Hello Gurus,
I dont find CALLMETHOD or CALLSTATIC commands in Ecatt. I am using R/3 4.7 version of SAP.
My question also is how to call methods. I have a scenario where my test script execution depends on the return type of method. Say if the return type of method is A only then I should run the script else the script should not be executed.
Your help in this regard is highly appreciated.
Regards,
GS.

Hi GS,
Please use the command "CallMethod" and it is available with latest SAP version.
You have to provide the Object Instance Parameter and Instance Method.

Syntax for how to call method of one comp in other comp     wd java.

Let us assume,
there is method1 in view1 comp1.
tell me syntax for calling method 1 in view2 comp2
thanks in advance.
Edited by: madhu1011 on Nov 9, 2011 11:31 AM

Hi Madhu,
This is the situation:
comp1-> method 1 , view1
comp2-> view2
You need to access method1 in view2 of comp2.
For that, do the following steps:
1.) First create a method (for eg: method1) in comp1 (under implementation of view1).
        eg: public void method1(){
                <......some logic...>
2.)Save the meta data.
3.) In comp2, you will find an option called used components. In that right click and add the component comp2. (Carefully select comp1 itslef).
4.)Save the meta data.
5.) Then go to view2 of comp2 and take implementaion part and right the following logic in wddoinit() (or any other standard or custom method).
wdThis.wdGetComp2Interface().getMethod("method1");
By this way, we can access the method1 of comp1 in comp2.

Jithin

CALL METHOD ABAP run SQL wrong

Dear All
         I have a problem in ABAP connect SQL,Below is my code snippet sentence.
CONCATENATE 'Insert Into [timportcortrol]'
                '(zucode,zstate,zdate,zkind) Values('''
                  VG_PCID ''','''
                  '1'','''
                  SY-DATUM ''','''
                  '1' ''')'
                 INTO SQL.
    CALL METHOD OF REC 'Execute'
     EXPORTING #1 = SQL
     #2 = CON
     #3 = '1'.
IF NOT SY-SUBRC = 0.
    MESSAGE I000 WITH 'Download to [timportcortrol] failure，Please Check the SQL Connect!!! '.
    EXIT.
ENDIF.
Con:is the connect SQL String ,the connect SQL is Okay.
I debug this code,when I used u2018Select u2026sentenceu2019,the program can work.if I use u2018insert intou2019 then canu2019t work,but I copied the SQL of the u2018inset Into sentenceu2026u2019run it into SQL server then it can work also.
And I found the SY-SUBRC eq u20182u2019.whatu2019s mean about of the sy-subrc eq u20182u2019.
I think the insert into sentence in abap I have write the wrong ,but I canu2019t assurance.
The Insert Into Sentence is:u2019 Insert Into [timportcortrol](zucode,zstate,zdate,zkind) Values('20080807094713','1','20080807','1')u2019
Could you give me some advice for this issue?
Thanks of all
Sun.

Have you checked whether it's a problem with mixed case? Some SQL dialects are case sensitive.
The not very helpful meanings of the sy-subrc value can be found in ABAP help.
