Prevent double running the same FORM application

Dears,
Anyone knows how to prevent users from running same FORM application in the same computer twice? Is there any ways to detect the application is already running and refuse to run it again?
Thanks,
Vic

i have a tree-menue where i use code like this in the when-tree-node-activated trigger which opens new forms:
frmId := find_form(frmToOpenName);
-- Open form only if there's no instance (for current user) of it at the moment
if id_null(frmId) then
open_form(.....);
else
go_form(frmId);
end if;
of course, if the user opens another tree-menue, he can open the same form again. but in one browser (i use 9i), he can open it only once.

Re: Running the same (Forte) application multiple times -for different

Hi
We had the same problem - how to deploy a number of identical applications, using each their own db.
(for training).
The solution we used is to wrap the entire application into different applications by using a very small
module called KURSUS01, KURSUS02 etc, that did nothing but call the start procedure of the main app.
Then in the dbsession connect, we made a call appname to get the application name, and appended the
first 8 chars to the dbname. Thus our dbnames now points to logicals name: rdbdataKURSUS01, rdbdataKURSUS02 etc.
All this allows us to deploy the identical apps in the same env, or change one version, and run both the old
and new program on the same pc and server at the same time (eg. KURSUS01 and KURSUS02).
I also think this is a kludge - but it works nicely!

Subject: Running the same (Forte) application multiple times - for different business clients.
Hi All
We have a number of different business clients all willing to use our
application.
The (forte) application is to run on our machines etc for these (business)
clients.
All (business) clients will have their data kept in separate Oracle DBs
(instance).
The problem now is that the entire (forte) application is written using
DBSessions.
Now, depending on what business client needs to be serviced (so to speak) we
need to attach to the right DB - or use the "right" SO.
The two options we can think of are:
Option1:
Programatic change to somehow "know" what (business) client (DB) I'm talking
about and then use the right DB.
Pro:
Only one forte environment to maintain
Can run multiple (business) clients on same PC at the same time
Con:
Requires many program changes
bending O-O rules(?)
can't dynamically name SOs so can it be done at all? (ResourceMGRs maybe?)
Option2:
Use separate environments! One for each business client.
Pro:
More defined separation of app and data,
SLA-easy
Con:
Maintain "n" number of environments
Can only run the application for one environment (business client) at a time
on one PC - Big Negative here!
Not knowing any feasible solution to option 1 (without much code changes and
developer moaning) I would go for option two; as I have already worked on
multi-environment setups on VMS back at the Hydro (hi guys).
I would appreciate any comments from anyone who has solved this problem.
How, Why Pro Con etc.

Prevent multiple users from editing/approving the same form SPD 2013,SP 2013

Hello all, I have a workflow with a to do task, the task is assigned to a group so any of the users in that group can go in and do a quality check on form data and approve it. How do I prevent multiple users from working on the
same form? do I just require check out? or is there a way to notify the rest of the group that a user has already started the quality check.

The "Require Checkout" option is your best bet. You can also enable the auto checkout on edit option to allow minimal effort on the side of the user. Other users will then get the error message stating the item is checked out, if they try to
edit it.
If you'd like, you could add a workflow to the task list that triggers when something is changed. That workflow can check if the item is checked out and if so, email the other users assigned to the task.
I trust that answers your question...
Thanks

Prevent running the same program twice or more + some other..

Hi All,
I'm trying to figure out how to do the following
1) How can I prevent a user from running the same program more than once.
2)If a user try to shut down the computer while my program is running, I need to trap it down and save some data before terminating the program, how can I do it?
Can any one help me???
thanks a lot in advance!

Prevent multiple users accessing the same form

hi,
i am working in forms
i have a requirement like this
if more than one user are using the same form and try to access the same record then the second user should not be able to do transaction
he should be popped up with a msg saying that other user is working on it
can any one suggest how to do this in my form
thanks in advance
selvaraj s

That is pretty much exactly the way Forms works automatically.
Two users can use the same form, and can even display the same data record. One of the users can make changes to the record -- Forms locks the row upon the FIRST keystroke in the first field the user begins to change.
Once the row is locked, the second user is free to look at the record, and won't even know if another user has begun making changes. However, if second user tries to change even one field in the record, Forms pops up the message, "Could not reserve record (2 tries). Keep trying? Yes / No"
There are also protections so if the first user actually changes the row and commits, then the second user tries to make a change. Forms will automatically detect whether changes were made, and if so, will undo the change and issue the message, "FRM-40654: Record has been updated by another user. Re-query to see change."
The above automatic processing works very nicely. If it will not work for you, then what is it you need?

How to insert a UUID into multiple tables in the same form

I am trying to insert a UUID into 2 different tables at the
same time ie to let this be created in the form and then insert
this ID into 2 linked tables in a database using Access.
Does anybody have any suggestions on how to accomplish this?
Thanks very much

So you have one form that processes information for two
tables, or do you
have two forms (one for each table - except the UUID)?
If it is one form just run two SQL insert statements. One for
the primary
table, then one for the related table.
If it is two forms run the above two SQL statements then an
update statement
to finish filling the second table.
Or am I completely misunderstanding the issue?

Can Bootcamp and Parallels share the same Windows applications and data?

I'm looking at getting an Intel iMac which will let me throw away my old PC - Yeah!
I will have a couple of Win apps that I will need to hang on to (Quicken - Quicken for Mac is horrible, but that's another tghread). Anyway, can Bootcamp and Parallels share the same Windows applications and data?
My thought would be to allow my wife to access Quicken from Parallels and not have to reboot. She will only need lightweight access and the overhead of running virtualization wouldn't impact her. I, on the other hand, would want to occasionally boot natively into Windows and run the same application with the same datafile. Is this possible?
Thanks and looking forward to joining the MacIntel world!

Thanks for all of the freplies. I suspected that BootCamp and Parallels could not shar ethe same partition, but wanted to verify. To address some of the other posts:
Re: Quicken vs MoneyDance - I looked at MoneyDance a while back and while it is comparable to Quicken for Mac, it isn't comparable to Quicken for Windows (ergo, Quicken for Mac isn't comparable to Quicken for Windows!). But, as I said, that is a topic for another thread!
Re: Using Bootcamp/Parallels for only one app: I actually have several apps that I still need access to on Windows. I work with many business applications than only run/are supported on Windows as well as receive some complex Office documents which Office for Mac cannot handle. Quicken (for Windows 2007) was just the best example of a consumer app where I could see wanting access from both OS X and Windows.

MouseEvents and KeyEvents in the same form is not working

Hello!
I'm newbee in java althought i've bee programing for a long time in other languages, C, C++ wich i'm proud of.
Now i land on java and there are a lot of cuestions (nothing that cant be solved by trying and reading).
But today i hitted my head against all posible solutions and nothing (but bad mood) came out.
The code with trouble is this...
public class NewJFrame extends javax.swing.JFrame
    public NewJFrame()
        initComponents();
    private void initComponents() {
        jButton1 = new javax.swing.JButton();
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyPressed(java.awt.event.KeyEvent evt) {
                formKeyPressed(evt);
            public void keyReleased(java.awt.event.KeyEvent evt) {
                formKeyReleased(evt);
            public void keyTyped(java.awt.event.KeyEvent evt) {
                formKeyTyped(evt);
        jButton1.setText("jButton1");
        jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                jButton1MouseClicked(evt);
        pack();
    private void formKeyTyped(java.awt.event.KeyEvent evt) {
        Integer i = evt.getKeyCode();
    private void formKeyPressed(java.awt.event.KeyEvent evt) {
        Integer i = evt.getKeyCode();
    private void formKeyReleased(java.awt.event.KeyEvent evt) {
        Integer i = evt.getKeyCode();
    private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {
        Integer i = evt.getButton();
    private javax.swing.JButton jButton1;
}In debug mode i cant listen to mouse events and key events in the same form. Is that normal ?
In case this is normal, how can i surround this "problem" and make it work.
Thanks a lot in ahead.

Thanks for trying to understand whats going on ...

}It's quite simple, its suposed to show on the windows title the KeyCode (if there is any) or the MouseButton when pressed.
The problem is: it doesnt work... (if i comment out the jButton1 related code, that means that i dont listen to MouseEvents & dont add the MouseAdapter as MouseListner to the form, the KeyEvents are raised and i can listen to them - but there are no MouseEvents - if i run the SSCCE like above i can listen to the MouseEvents, but cant listen to the KeyEvents. Can you tell me why?
Just before posting i realized it was a focus issue ! The button got the focus and got all the events redirected towards him ! I solved it with the code
        jButton1.setFocusable(false);and it finally worked !
Thanks!

Backup-restore vs running the same SSIS datacopy project twice

I have 2 different applications which need the same source data which is copied from a production database. The 2 applications run on different servers, so they can not use the same source database. The way I see it, I have the following two options:
1. I develop a SSIS solution to load the required data into the source database and run the same project on both servers, creating 2 identical source databases.
2. I develop a SSIS solution to load the required data into the source database, run this solution on one of the servers. I then create a job on this server to make a backup after this process is done and restore it on the second server, also creating for
me 2 identical source databases.
Which method would be more efficient and why? (what also might be relevant is that one of the two sourcedatabases needs to refresh every night, the other one only once a week)

I would definitely use backup and restore. It will consume fewest resources and you *know* that the data is identical.

Help:How can I run the J2EE Client Application? Thanks

Help:How can I run the J2EE Client Application that will access the remote J2EE1.4 application server which runs on another host computer?
I have developped a stateles senterprise java bean name converter and deloyed it in the j2ee1.4 application server on the host machine A. The converterbean provides the remote home interface and remote interface. At the same time I have developped the j2ee application client named convertappclient. When I access the conveter bean at host computer A through the script 'appclient.bat' as 'appclient -client convertappclient.jar', the client can access the bean sucessfully. Now I want to access the bean through the script 'appclient.bat' at host computer B,what files should I copy from host computer A to host computer B;and what the command line should be like? Thanks!

Is it possible that you are using the same password for the old O2 Study and newer O2 Apple Base Station networks?
If so, Keychain Access is storing the old information about the old network and may be associating it with your AirPort Extreme settings based on the BSSID that William has mentioned.
If that's the case, open Macintosh HD > Applications > Utilities > KeyChain Access and look for a listing with the old network name. Delete this entry. You may need to power down both the computer and the AirPort Extreme and restart them.

How to retrict user cannot open the same form more than once (Forms 6i)

Our users always open the same forms more than once. For example the customer form, the user may access a customer record in the first form, however, he will open a new customer form to edit the same record, the result is he cannot save the record because the record is locked in the first customer form.
How can I control the user cannot open the same form more than 1 time.
Best Regards,
Kane

The customer form is only an example, I found there will cause a lot of problems is I cannot control the user from calling 1 program more than 1 than within application. Sometimes a user (not good in using computer) will overlap the form for many times.....
Is there any simple way to do that?...can I have some PL/SQL statement or build-in functions that let me easily found our what forms the user has already opened, then I can control whether I let him open this form or not.
Urgent...please
Thanks

Can the same NDS statement be used by other users running the same program?

Say you have an NDS statement running in an application. We have users all over the country running this package off of the same database. If an NDS statement gets stored in the Library Cache than would other users running the same package use that NDS statement or would their processes spawn another yet identical NDS statement?

There is no difference in the caching of dynamic or not statements. If statement is already in cache and it's session environment is similar to current session one then statement will be soft-parsed.

How do I get System.out.format to print out doubles with the same precision

Using the System.out.format, how do I print out the value of a double such that it looks exactly like it does if it were print from a System.out.println.
For example, take the following code:
double d = 12.48564734342343;
System.out.format("d as format: %f\n", d);
System.out.println("d as sout: " + d);Running the code, I get:

d as format: 12.485647
d as sout: 12.48564734342343

The precision of d has been lost.
I could bump up the precision as follows:
double d = 12.48564734342343;
System.out.format("d as format: %.14f\n", d);
System.out.println("d as sout: " + d);That appears to work, I get:

d as format: 12.48564734342343
d as sout: 12.48564734342343

However, that solution fails if d has a different precision, say 12.48. In that case I get:

d as format: 12.48000000000000
d as sout: 12.48

So how do I get System.out.format to print out doubles with the same precision as System.out.println?
Thanks..

Interesting, but this is not what I am looking for...Your original question was "how do I print out the value of a double such that it looks exactly like it does if it were print from a System.out.println", and you've been told how to do that (although the pattern given by sabre may be a bit excessive - you should only need 15 '#'s).The initial phrase from my question was "Using the System.out.format, how do I..".
It's worth remembering that, unlike the Format hierarchy, 'format()' is NOT native to Java. It's a convenience implementation of the 'printf()' and 'sprintf()' methods provided in C, and first appeared in Java 1.5. Those methods were designed to produced fixed-format output; 'println()' was not.Perhaps it is the case that this can't be done.
Furthermore, Double.toString(), which is what is used by println() does not produce the same format in all cases; format("%.14f\n", d) does. TrySystem.out.println(1.8236473845783d);
System.out.println(1823647384.5783d);and you'll see what I mean.I am fine with that. It still displays all the precision.
I am simply looking for a way to quickly print out multiple variables on a sysout while debugging. I want it as syntactically sweet as possible. System.out.println can be a pain when outputting multiple variables like the following:
"System.out.println("a: " + a + "; b:" + b + "; c: " + c);"
For some reason, my fingers always typo the plus key.
I was hoping that System.out.format would be easier,along the lines of:
"System.out.format("a: %f, b: %f, c: %f\n", a, b, c);"
From a syntactical sweetness point of view, it is easier. However, the %f on doubles truncates the precision. I figured there must be a way to get the full precision.
DecimalFormat is syntactically sour for this purpose, as you need to instantiate the DecimalFormat.

Can I print a multiples copies of the same form using a counter. For example I like to print 200 copies and I have a variable or running toatl that can be incremeted by 1 trought the copies.

I used to be able to print multiple copies of the same picture on one page using iphoto. There was a customise button when you went through to print and it was there somewhere. I can't see it anymore - maybe since an upgrade.
It's gone. But as a work-around, duplicate your photo (⌘D) to create as many versions as you want copies and select all at once. Then use the "Custom" print layout and set the photo size you want.
After printing, trash the added versions.
