Why do we use cl_gui_cfw= flush method in Object Oriented ALV programming
Dear Friends,
Please solve my query regarding control framework. Why do we use cl_gui_cfw=>flush method in Object Oriented ALV programming. I studied and found that this method transfers automation queue to Front end. But I could not find any further update on this.
Thanks & Regards
Amit Sharma
Generally this is to restrict the traffic b/w frontend and backend. This means that every operation in Control Framework should be first buffered in the backend and synchronized with the frontend at certain points (one of this point is calling synchronization method cl_gui_cfw=>flush ). This explicit order of synchronization is due to RFC call needed for every communication b/w front/back end. So to avoid to many RFC calls we do it only at certain time.
Please refer [Automation Queue|http://help.sap.com/saphelp_wp/helpdata/en/9b/d080ba9fc111d2bd68080009b4534c/frameset.htm]. I think it explains the concept quite well.

How to use LDB PNP with ABAP objects in a program
Hello,
I am wondering if anybody has used the HR logical database(LDB) PNP with user defined ABAP objects in a program? I am using the FM- <b>LDB_PROCESS</b> but its not working. Also assigning PNP in the attributes section of the program -- so that I can use predefined fields from the LDB and then invoking the FM doesn't work -- throwing 'Logical database already active' error.
I suppose even with the ABAP objects and the new FM -- I should still be able to utilize the pre-defined fields of the PNP database -- and also the built in authorizations. I cannot use GET PERNR and REJECT as they give errors. I understand that the use of HR-macros (RP-PROVIDE-FROM-LAST and et al.) are not allowed as they use the table work area -- which is not allowed in ABAP-OOPS.
I would really appreciate if anyone could show me some insight regarding this. Thank you.
Kshitij R. DevreHi Kshitij
It would be really good if we could use both together. But as I know, it is not possible. "GET pernr." is an event-like loop statement and so cannot be used in OO context. And I guess, the same restriction holds for the "LDB_PROCESS" since it uses LDB-specific processing.
What I suggest you is to use standard and BAPI functions.
Sorry for giving bad news...

Hi Everyone,
I am really very new to Labview and i am in great need for some help.I am assigned a task where i am supposed to create a labview program to control or moniter a BPC203 3 channel benchtop Piezo controller. I created a program with the help of the instructions provided in the APT-Labview guide provided by Thorlabs.But th program doesnt run . Whenever i try to run it i get the same error which says that "Control HW Communications disabled".I have attached a snapshot of the error message.So i tried to create a small program in labview which would read the volage output.Even there i got the same error message.I suppose there is some mistake on my part which i am not able to correct due to the lack of proper knowledge.Could anyone please help me to solve this problem.A slight elaboration would be highly appreciated.Also i think the error lies in the use of invoke node with the get Voltage output method. I am not sure whether the parameters i have provided to the invoke node are correct.Any help of any sort would be highly appreciated.
Attachments:
Front Panel with error message.PNG 202 KB
Block diagram.PNG 101 KBHi
I had the same problem today. However, I noticed that the piezo controller has 3 channels with separate slots and they are packaged in the same box. Therefore the whole box has a serial number, probably something like 71822280, and this is written with large letter. Now, in order to communicate with any of the channels, this does not help, but one needs to communicate directly with the interested channel and they have thier OWN SERIAL NUMBERS.
For example channel 1 (my X direction in the nanoMax stage) has serial 91822281, Y has 91822282 and Z has 91822283. So try looking if you have the right serial number Hopefully you found out this yourself but this might help others, I took me3 hours to get this thing working when I started to plug-in the cables and everything.

When to syncronize automation queue (calling cl_gui_cfw= flush)
Hello,
I'm using OO ALV (using cl_gui_alv_grid class), with checkboxes and user interaction, and it all seems to work OK. But i'm not calling class method cl_gui_cfw=>flush in any point at my program, because I don't clearly understand what's the method's use and need.
Could you please explain this to me? I've already read some SAP help about control framework, automation queue and all but still don't get it (so please try to explain instead of simply pasting SAP help links).
Many thanksOk, from your last post i deduce that for every control class (i.e. cl_gui_alv_grid), there's a proxy class in the application server. All that is transparent to the programmer.
But could you give some example of when the necessity arises to use the flush method explicitly?
My ALV code in this case isn't much complicated, i just call the check_changed_data method to detect changes in checkboxes and then call refresh_table_display. But would like to understand this fully so I can be prepared for any case.
EDIT: I guess the need depends on the context of the program being developed. But I understood the concept so I'm closing the thread.

Hi, why do we use the break and continue structure?
Hi, I was wondering why do we use the break and continue structure in some program such as:
for ( int i = 1; i <= 10; i++ ) {
if ( i == 5 )
break;
So, now why do we use those codes, instead of achiving the same results by not using the if structure.
I am new in java so I can be totaly wrong that is why my question come to you guys.
I will appriciate if you let me understand more.I may not completely understand your question, but - imagine the following scenario:
// Looking for some value in a long, unsorted list
Object target = null;
int index = -1;
for (int i = 0; i < list.size(); i++) {
Object curObject = list.get(i);
if (curObject.equals(source)) {
target = source;
index = i;
if (target != null){
System.out.println("Found it at " + index);
}You will always run through the entire long list, even if the thing you are looking for is the first thing in the list. By inserting a break statement as:
// Looking for some value in a long, unsorted list
Object target = null;
int index = -1;
for (int i = 0; i < list.size(); i++) {
Object curObject = list.get(i);
if (curObject.equals(source)) {
target = source;
index = i;
break;
if (target != null){
System.out.println("Found it at " + index);
}You can skip whatever's left in the list.
As for continue, yes, I suppose you could use a big if, but that can get burdensome - you end up with code like:
for (int i = 0; i < list.size(); i++) {
Object curObject = list.get(i);
// you want to do the rest only if some condition holds
if (someCondition) {
// do some stuff -
// And you end up with lots of code
// all in this if statement thing
// which is ok, I suppose
// but harder to read, in my opinion, than the
// alternative
}instead of
for (int i = 0; i < list.size(); i++) {
Object curObject = list.get(i);
// you want to do the rest only if some condition holds
if (!someCondition) {
continue;
// do some stuff -
// And you end up with lots of code
// all outside of any if statement thing
// which is easier to read, in my opinion, than the
// alternative
}Hope that helped

Java is pure object oriented programing language or not why?
please clear
java is pure object oriented programing language or not why?And there is some concepts of object orientation that
Java not implements like: Operator
Overloading and Multiple Heritage. But, i think
that we can live without those features.
And the sucess of Java is a proof of this.I don't believe that operator overloading and multiple inheritance are required aspects of object programming. -
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.
MESSAGE i888(sabapdocu) WITH text-003.
CALL METHOD sender->get_selection_pos

Hi all,
what is the use of the class cl_gui_cfw=>flush. in alv object?
Thanks
ANUPAMHi,
Use this method to synchronize the automation queue. The buffered operations are sent to the frontend using GUI RFC. At the frontend, the automation queue is processed in the sequence in which you filled it.
If an error occurs, an exception is triggered. You must catch and handle this error. Since it is not possible to identify the cause of the error from the exception itself, there are tools available in the Debugger and the SAPgui to enable you to do so.
Debugger: Select the option Automation Controller: Always process requests synchronously. The system then automatically calls the method cl_gui_cfw=>flush after each method called by the Automation Controller.
SAPGUI: In the SAPgui settings, under Trace, select Automation. The communication between the application server and the Automation Controller is then logged in a trace file that you can analyze at a later date.
CALL METHOD cl_gui_cfw=>flush
EXCEPTIONS CNTL_SYSTEM_ERROR = 1
CNTL_ERROR = 2.

Why do we use init() method instead of constructor to initialize a servlet?
Why do we use init() method instead of constructor to initialize a servlet?
I suspect the reasons are partly historical. A servlet is loaded dynamically, by class name and, once you've loaded the Class, it's easier to to a newInstance, using the default construtor than it is to search for a particular matching constructor and invoke it.

Why can't I use rs.deleteRow() method to delete a record?
the code as such�F
<%
String sql="select id,name from test";
ResultSet rs = jconst.executeQuery(sql);
rs.next();
out.print(rs.getInt("id"));
try
rs.deleteRow();
catch (SQLException e)
out.print("can't delete record");
return;
out.print("success");
%>
the result is "can't delete record" ,why? I use mysql database�C"jconst" is the bean of connect to mysql database! In the "jconst" bean , I use such method to return Resultset :
public ResultSet executeQuery(String sql)
rs = null;
try
conn = DriverManager.getConnection(ConnStr);
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
rs = stmt.executeQuery(sql);
catch(SQLException ex)
System.err.println("aq.executeQuery: " + ex.getMessage());
return rs;It's again the problem with not commiting the changes to databse. In order to commit changes to the database, you need to call the commit() of Connection explicitly or simply close the Statement and Connection objects in your bean.
After rs.deleteRow() in your jsp you call another method of your bean jconst.saveChanges(); and add this method in your bean.
public void saveChanges() {
try {
stmt.close();
conn.close()
} catch(SQLException sqle) {
//handle the exception
I hope this will work.
Sudha
PS: It's not a good practice to manipulate the database from your JSP. JSP is meant for presentation. You can do all these operations from bean itself.
