Tracking program flow.

Hi,
I was wondering if there were some way to ask JVM to keep a track of all classes accessed during runtime and print them to a file.
Is this possible??
Thnx.

Thanx Kaj,
But,
java verbose:class only displays class names as they are loaded.
Subsequently if you access some method of the loaded class it wont show up in the output.
What I was hoping for is, if there were some way to print class names as they are accessed. This would help if I was learning the workings of an application written in an obscure framework, for instance.

How to track the flow of Sharepoint SSRS report requests to troubleshoot slowness

How to track the flow of requests of Integrated SSRS report links in Sharepoint.
We are using SSRS with Sharepoint for reporting purpose. The issue is some of the reports get generated fast and some other reports generation is very slow. When the sql query of these reports RDL file is executed, the records are shown fast.
Also even on clicking the "Add Subscription" link of "Manage Subscriptions" of a report is very slow for some reports, while it is fast for other reports.
I tried enabling SQL profiler to track the requests. I have checked profiler log for the SQL statements with exec sp_executesql. But they are not helpful.
Pls advice on how to track the request of flow of SSRS report request in sharepoint and how to troubleshoot the slowness in "Add Subscription" link, response of some reports.

Hi Pradeesh,
According to your description, my understanding is that you want to track SharePoint SSRS report requests to troubleshoot the performance.
Developer dashboard is very help full while troubleshooting the issues related to performance in SharePoint 2013. You can have a try.

Asset tracking program

Hi all
there is a program that im not sure how to go about doing, that wants to create an asset t-racking program that will track 4 types of assets: electronics, automobiles, furniture and cd's. Which classes would you use to design this program? would you define four unrelated classes or one superclass and four subclasses? if you design a superclass, will it be an abstract superclass?
Implement the asset tracking program. allow the user to add, modify and delete electronic appliances, auto's, furniture and cd's. allow the user to list the assets by category and search for an asset by its serial number...
I was thinking of utilizing an arraylists in this program. Any suggestions on how to approach this problem would be great thanks :/

I'd start with a pencil and a blank sheet of paper. An abstract Asset class and concrete child classes seem to be a good place to start. What information is common to all your assets? For example, asset number, asset description, purchase date, purchase price, accumulated depreciation, current location.
What information is unique to the child classes? Serial numbers on automobiles and electronic gear? Automobiles have lots of identification numbers: engine numbers, VINs, registration, insurance. CDs have a title and artist(s) with tracks. Furniture is different again, type (desk, chair, etc), colour, finish.
You need another class with collections of assets, perhaps AssetRegister. This is the class you put methods in to list and search assets.

How to track the flow of data from R/2 to BI ?

Hi Experts,
Question: How to track the flow of data from R/3 to BI ?
I want to load master data from R/3 to BI. In BI, i create an infopackage to load data from R/3. Under processing tab i set it as "PSA and then in the InfoObject (package by package)". Its a Full update.
Now, i start the update to InfoObject. The load goes on well.
Now, i want to track the flow of data from the master data table in R/3 to Datasource in R/3 then Extractors and then in the PSA in BI and then till the InfoObject. That is the complete flow of data from source table (in R/3) to Target table (in BI).
Please help me know how this can be done. (For example lets take cost element master data)
Regards,
Suraj S Nair

Hi,
Data flow :
BW :
When u right click on the Master Data Info object -> Select Data flow.Then it will show u the details like DS name,IS (If 3.x)
Once u know the DS then you need to find out the source tables for the R/3 DS.This information will get using ROOSOURCE or ROOSFIELD tables or help.sap.com.
My suggestion better to search in Help site for DS source tables.
DS Tables :
The following link will provide you the source tables for some of the LO DS.

Hello,having a problem with Logic 9 on a Mac Pro.Working on a lenghty song and apparently session got corrupted.Doesnt let me export tracks,program crashes.Already tried start brand new session with the tracks imported into it but still wont export.Suggestions?

Thanks, Ian. Yeah, that's how I do it now...or with the controls in the left side pane. Still, I would have liked that quick on-the-spot edit capability...especially while sketching.
Ian Turner wrote:
Sorry Mark, you are out of luck as it does not do that - it works the same as L8. The way I would achieve that with more accuracy and control would be to route all the tracks you want to fade to a Bus then use volume automation on the bus. To do this you will need to add a standard audio track, then re-assign it using (Control Click on the track header) to the Bus track. You can then automate volume/plugins etc on the Bus track.

Dialog Box simulation without interrupting program flow

I'm developing data acquisition/control software and need to give the end
user flexibility to change the file to which the acquired data is being
saved during operations. In the past, users have been confused with a
simple string control that specifies the data file path, so I would prefer
to move to the popup/dialog box standard to windows. Unfortunately, calling
a dialog box results in the stoppage of program flow for the caller until
the dialog box is closed (even though there may be no apparent data flow
from the popup VI.) and stopping the program flow is not an option for this
control system (the computer is controlling pressure, temperature, flow
rates, etc of a very expensive and sensitive bit of hardware, so halting the
control function for an unknown length of time is unacceptable).
I am looking for the best way to accomplish this under LabVIEW 6i.
Using a VI class reference through VI Server, I can essentially detach the
popup window from the base program execution, spawning a separate
application and passing the relevant parameters through judicious use of
global variables. If I call the subroutine via VI server with "Wait until
done" attribute set to false, the appropriate VI appears, functions
correctly, and terminates as expected. Unfortunately, it remains visible on
the screen, an inactive application. I have the VI Properties -> Window
Appearance -> Customize -> Show Front Panel When Called and the Close
Afterwards if Originally Closed checkboxes checked on this popup VI. It
seems that calls through VI Server trigger the "Originally Open" flag, so
the window does not close as I had expected.
The way I have found to get around this problem is to use VI Server to call
an intermediate subroutine whose front panel is not displayed and whose sole
purpose it to call the subroutine that calls the dialog box. This does what
I wanted, essentially. When the user wants to change directories, they
press a button that triggers a call to VI Server to open a separate
application. This application's front panel is never displayed and only
calls a sub-VI that performs all the actual work and ends when it is
completed. As this sub-VI terminates, all visible traces of the subroutines
disappear and I'm left with just the primary program executing, continuing
to take and send control signals through this whole process.
This seems a rather cumbersome way to get a custom dialog box on the screen
without stopping the program flow of the caller, however. Is there a more
efficient way to accomplish this?

Wouldn't it be easier to use two parallel independent while loops in the
main vi, with one taking care of acquisition and the other of user
interaction.
When the UI loop is temporarily 'halted' because of the dialogue box poping
up, the acquiring loop continues without delay.

Application to visualize program flow

I'm looking for an easier way to "visualize" what is going on in the source code of a large project, in regards to function calls, method calls, and classes.
For example, a source directory of a project will have a bunch of files, like this:
anim.c
character.c
direction.c
game.c
input.c
main.c
player.c
resources.c
room.c
screen.c
If I didn't know anything about this project, if I wanted to try to understand how it works it would be difficult to start.
Does anyone know of an application that will read source code and display a tree-like output of the program flow? For example, maybe like this:
main() [main.c]
-> create_game() [game.c]
-> reset_timer() [timer.c]
-> update_game() [game.c]
---> update_world() [world.c]
---> is_game_over() [game.c]
---> ...
-> draw_game() [game.c]
---> draw_world() [world.c
---> ...
-> destroy_game() [game.c]
How about for classes and method calls?
I don't care if it's GUI or CLI, or what programming language it's for. I think a program like this would be incredibly useful, especially in the FOSS community, and would be surprised if something doesn't already exist.

cflow - For C programs. Nice and simple.
KCacheGrind - Uses the "callgrind" application. I couldn't find callgrind in the Arch repositories or the AUR, so I gave up.
codeviz - For C and C++ programs. I got it to produce a beautiful PNG tree of all of my function calls. I probably won't use it. A graphical tree output isn't so useful to me, and it was a bit tricky to actually setup and use. (for example, it requires a patched version of GCC)
egypt - For C programs. Super duper simple concept, but requires some setup to use. I couldn't figure out how to configure and run it.
gprof - Part of the GNU Binary Utilities. A little too low level for what I was looking for.
pycallgraph - For Python programs. I didn't try it.
doxygen - Is able to create documentation for anything in the world, including your car. I wish someone could tell me, "Type this doxygen command to create a call graph", but until that happens, I just can't seem to figure it out.
cflow is definitely my favorite. I will do some post processing to the output to remove any functions that I didn't write.
EDIT: Someone did a similar "review" to mine here, along with mentioning more programs to try out: http://grok2.tripod.com/code_comprehension.html

Any Patient Tracking Program out there?

Does anyone know if there is any simple patient tracking program out there?
Functions that will be needed is patients demographic information, name ,age, sex, number of times they visited, patient number visits in a single day, as well as a way to bill them and invoice upon visit.

If there is nothing specific you can research FileMaker Pro for any ready made forms they might have that would be similar in nature to what you want.

Simple Tracking program

Hi
I am still learning the techniques of java and would like some help if possible. I am trying to create a simple tracking program which tracks what letter has been typed. For example if an A was pressed then the A label would turn blue. Then if another key was pressed then it would return to its default state white. I have created all the various labels for each letter and now have to do the programming of the tracking.I want it in the end to work out that when each letter key is typed on the keyboard then their various label would turn blue. If any of you have any hints or tutorials that would help me with it, I would be thankful.
Nico

I am still learning the techniques of java and would like some help if possible.Still learning how to ask a question as well I see. Much information is missing. For example:
a) is this Swing or AWT (there are separate forums for each, instead of using the general programming forum)
b) what kind of component has focus. A text field a panel?
In general, you would probably use a KeyListener or a DocumentListener. Read the [Swing Tutorial|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html] for examples of both.

Booleans to control programming flow

Is it ok to use booleans within an object to control program flow in an Object Oriented approach?
For eg: I have 2 tables in the database which are related. Some times both the tables need to be updated, other times, just 1 table.
One approach would be to have 2 separate methods in the Data Acces object which handle these situtions, as this seems to be cleaner. However, another approach would be to send all the data along with a boolean to the Data Access Object and let the Data Access object make the decision of which tables to update by checking the boolean.
Please tell me which approach is better and more Object oriented.

1. How often will the Two tables be updated together.(Not a major factor)
2. Keep both methods you mentioned.
3. Create a new method that takes the boolean and the data to update.
and use this in it:
(boolean)?FirstMethod:SecondMethod;
If boolean is true then it calls FirstMethod else SecondMethod.
Anyone else think of anything?

ABAP program flow.

Hi,
whenever i write abap program, i usually maintain following program flow. is it right from performance tuning point of view?
1) include statements
2) DATABASE TABLES
3) VARIABLE DECLARATIONS
4) SELECTION-SCREEN
5) FIELD SYMBOLS
6) INITIALIZATION
7) AT SELECTION SCREEN
8) TOP OF PAGE
9) END OF PAGE
10) START OF SELECTION
11) END OF SELECTION
Please advise
Regards,
Santosh

Hello,
Just to add to Kathick's explanation. ABAP is an event-driven programming language. The general flow of an ABAP program is controlled by events.
It is a good -practice to code event processing blocks in the order in which they will be triggered during execution. However, they do not have to be coded in a sequential order.
This is the first thing i learnt in ABAP basics class )

How to stop the program flow

Hi all,
i need to stop the program flow control without entering into the start-of-selection.
i am using some manual conditions for validating some parameter fields...
i used Leave list-processing--->but it dosint works
call selection-screen 1000--->it works but when i click the back button the control goes inside the start-of-selection can any one help me with this....

If you want to stop the program flow in case one condition is satisfied, you can use STOP or EXIT command. Else, if you want to stop the program and debug it just but BREAK command where ever you want to stop the program. Also, if you want to validate the program selection at the time of entering the selection before the start of selection, you need to add AT SELECTION-SCREEN event block before the start of selection.

Don't know how to halt program flow

I posted a message on the Event Handling forum. Since no one responded, I am refering it to this forum.
The initial message is at
http://forum.java.sun.com/thread.jsp?forum=424&thread=543756&tstart=0&trange=15
I am new to Thread programming.
I want to pause the current thread from an event handler (from mousePressed(), to be specific), then do some animation that accesses the GUI and then resume program flow.
I tried various things, but no luck.
SOMEONE PLEASE GUIDE ME.
When the animation code is called and the thread is paused (by Thread.sleep()), the animation also pauses.
When I try using SwingUtilities.invokeAndWait , the following runtime error occurs:
"Cannot call invokeAndWait from the event dispatcher thread"

But the problem is that when the computer makes move, it does it so fast that sometimes the user
doesn't see which part of the panel is changing, wondering whether the program is making a legal
move. So, after calculating the move but just before implementing it , I want to halt the program's flow,
then animate (blink) the small region in the JPanel where the moves are going to be made (to draw
user's attention) and then resume the program to make moveYou're not allowed to pause the event dispatch thread (EDT) - otherwise your program will freeze.
I would suggest to use an event based solution:
public void actionPerformed(ActionEvent ev) {
    // move holds information about what happened on the scene
    Move move = logic.calculateMove();
    new MoveClue(move).start();
public class MoveClue implements ActionListener {
    private Move move;
    private Timer timer;
    private int count;
    public MoveClue(Move move) {
      this.move = move;
    public void start() {
      timer = new Timer(1000, this);
      timer.start();
      // perhaps you should block input to your panel, e.g. utilizing a glasspane
    public void actionPerformed(ActionEvent ev) {
      // display a clue using the information from the move object,
      // e.g change background color of a region
      if (counter++ > 5) {
        timer.stop();
        // unblock your panel
}

ABAP Object program flow

Hi all,
I'm starting to play with ABAP Object, and am very comfortable with OO features (coming from Java).
Currently, I am hesitating on the way to code my program flow. Let me explain:
Is it common practice to manage the screens flow within methods (with SET SCREEN etc.)?
I would think that this is kind of bad, since it requires local classes, and is simply kind of weird (to someone coming from Java anyway). Is continuing to handle this via MODULES and such still a good way to go?
Thanks for any enlightenment you can bring me.

Hello,
First, I din't mentioned that you said JAVA is better. I just said the things what u can do in JAVA u can achieve and there is a way in ABAP also. I tihnk u misunderstood my statements. :)..no hard feelings...
Ok.
BADI's are kind of Exits. To make it in a simple statement SAP has provided us with a way to enhance the business process.
For example, assume that a business process goes thru step 1, step 2 and so on. Inbetween step1 and step2 you want to do something. For this SAP has provided some standard interface, which will get the information about the business process in step1 in to it. You can make use of that and customize according to your requirement.
Send me you mail ID I will forward good document on BADI's.

Change variable type during program flow

Hi there. Please tell me is there a possibility in ABAP to change variable type during program flow? I'd be very thanful for suggestions. Greetings.

hi,
Make use of field symbols for that ...
