Combo box or similar where more than one selection can be made

Hi. I need to create a combo box field or similar where more than one selection can be made. Does anyone know if this is possible? I know this can be done with the check box tool but the client wants a drop down box. Thanks in advance.

I don't quite understand some of this but of course you can bind more than one object into the RMI Registry. If you use different names the clients will use the object corresponding to whatever name they looked up. If you rebind different objects to the same name, the clients will use the object that was there at the time they did the lookup.
Clustering is a problem for RMI/JRMP because stubs are not location-transparent: they refer to the originating JVM. If you need this kind of functionality I would use RMI/IIOP and do some CORBA magic in the ORBs at both the clustered servers. CORBA references are location-transparent so a service can be logically 'moved' from one JVM to another.

How more than one MDB can be made to run in single transaction

Hi All,
I am working on EJB 2.0 with Application server as Websphere 5.0 and Messaging middleware as WebSphere MQ5.3
I am facing a design issue, I need to use more than one MDB in single transaction unit. Since an MDB can only run in transaction started by itself I am looking for some alternative approach
The problem in detail is as below:
Consider there is an MDB M1 listening on Queue Q1
Bean M1 reads Message (say msg1) from Q1, writes another message into Q2.
We have a mainframe system which reads message from Q2 does some processes and write it's response into Queue Q3.
Now we have another MDB M2 in same application server listening on Q3.
The requirement is if there is any ERROR in message at Q3, transaction started by MDB M1 should be rolled back and hence the message (i.e msg1) should be put back on queue.
Since trancation started by MDB M1 and M2 are independent I do not have any control to rollback M1 from M2.
Pls suggest me what alternative approach I can use.

I think if you are using container managed
transaction and have set the trans attribute to
"required" then MDB M-1 and MDB M-2
should have same container transaction.
wrong !
There is never a client transaction context available when a message-driven bean is invoked because a transaction context does not flow with a JMS message. [EJB spec. 2.0 15.4.7]

How we can lock No more than one user can use the table at a single time

Hi Abapers,
0) which function modules to lock & unlock a table.
1) When you execute the program, we can check if there is any lock on this table. If yes, the user should be able to only view the table contents and not modify.
2) If there is no lock, then lock the table and go into change mode.
3) On exiting from the program, unlock the table using the function module.
4) more than one user can't modify the table just display.
Note: If there is any lock, display message saying table is locked.
Plz help me for this requirement.
Thanks
Nani

Hello Nani
Have a look at the lock object EMMARAE (Lock MARA and MARM/MAKT exclusively) in transaction SE11.
Inspect the F1 help for field Lock mode:
DE ENQMODE
Short Text
 Lock mode
Definition
 Defines how to synchronize table record access by several users.
The following modes exist:
 Exclusive lock
 The locked data can be read or processed by one user only. A request
 for another exclusive lock or for a shared lock is rejected.
 Shared lock
 Several users can read the same data at the same time, but as soon
 as a user edits the data, a second user can no longer access this
 data. Requests for further shared locks are accepted, even if they
 are issued by different users, but exclusive locks are rejected.
 Exclusive but not cumulative lock
 Exclusive locks can be requested by the same transaction more than
 once and handled successively, but an exclusive but not cumulative
 lock can only be requested once by a given transaction. All other
 lock requests are rejected.
If you want to lock a standard table search whether the table is used in lock objects (Where-Used-List). If it is a customer table you have to create your own lock object (including two function modules: one for enqueuing and the other for dequeuing).
The lock modules can be found in menu GoTo -> Lock Modules.
Given these lock modules the logic should be quite clear after starting the program:
1. Request lock -> if successful, continue in Change mode; -> if failed, continue in Display mode
2. Before leaving the report remove lock (note: no problem if no lock has been set in the beginning).

More than one selects in a function

Hi All,
Is it that there can not be more than one selects in a function?What is the work around for this thing?
Regards,
Amit.

Hi Krystian Zieja ,
Thanks for responding. I do not know what was going wrong but now it is working fine.
The problem is that I was not able to compile a function with two select statements in it. If I could comment one of the select statements it was getting compiled. But now it is getting compiled with both the selects.
Now since we are at it can you solve another of my problem. I want to see the output of my function. If I write DBMS_OUTPUT.PUT_LINE statements in it I am not able to see the output. Is there anyway that I can call my function and it can show the output on the screen.
I am using Benthic Golden 32 editor. Is there any way in it that I can call my function from it ?
Regards,
Amit.

How to make more than one person can access the database at one time

how to make more than one person can access the database at one time

Please post further f'up's in the Access forum.
In short: for different reasons it is best practice that each user gets its own local copy of the database. This means that you need to split it into a front-end which only consists of the forms, queries, reports etc. Everything which doesn't need to be
shared. And a back-end, which only stores the data.
Take also a look at Allen Browne's article:
Split your Access database into data and application.
When you've splitted your database, you may often consider to use SQL Server as back-end. Here you may read Armen Stein's
The Best of Both Worlds: Access-SQL Server Optimization.

I want to acquire data for multiple channels using PCI 6120 that works on traditional DAQ. I cannot access more than one channel, can someone help me or if someone has data acquisition vi for PCI 6120, please send me over . Thanks

I have PCI 6120 card and I want to acquire data for more than one channels. I'm using traditional DAQ to get it. But it does not work for more than one channels. If someone has a data acquisition vi for PCI 6120. Or some suggestion how to aquire data please let me know.
Thanks

Hello DSPGUY1,
You can definetly acquire from several channels. For your convenience, I have appended below the content from help that tells you how to configure it:
"channels specifies the set of analog input channels. The order of the channels in the scan list defines the order in which the channels are scanned during an acquisition. channels is an array of strings. You can use one channel entry per element or specify the entire scan list in a single element, or use any combination of these two methods. If x, y, and z refer to channels, you can specify a list of channels in a single element by separating the individual channels by commas, for example, x,y,z. If x refers to the first channel in a consecutive channel range and y refers to the last channel, yo
u can specify the range by separating the first and last channels by a colon, for example, x:y."
Hope this help.

More than one selection on the structure cause drill down failure

Hello Expert,
There is one structure, say stru1, with one selection, say sel1. The result on sel1 is OK. When to drill down on field, say fld1, is OK also.
To add a new selection, say sel2, the result on sel1 is OK. However, to drill down with the fld1, the quantity under sel1 is empty. But the total on sel1 is OK. And the drill down on fld1 under sel2 is OK.
Can anyone help?
Thanks
chen

Hello Brijesh
I succeed do this operation in other works, but not this. After performing drill down in the first dimension, i clicked on the second dimension and nothing happens.
It doesn't emit any error message.
Normally should be able to view the data calculated for the two dimensions. I have 6 small dimensions tables (average of 700 records). I don't know what can be.
Thanks,

Can only open firefox once, have to restart to open more than one browser. can't upload any pictures the box doesn't pop up, my browser settings are diff now

Firefox just changed out of nowhere. I can only open firefox once... I used to have atleast 2 browsers up using them both on different sites, but now I can't have but one firefox browser up (not tabs, but firefox pages) Also when I am trying to upload images on ebay or any other site nothing happens... nothing pops up. I click it over and over and nothing even pops up. This is exactly what happens with the firefox browser in my first question... I can click the firefox icon a million times and nothing comes up. My tabs are all gone and it doesn't show anything like I had before this all changed? Did I reset everything some how? I do not recall clicking anything to go back... I do remember clicking an update because it kept poping up so I did it and that is the last thing I remember before this happened! UGHHH!

As I asked previously are you able to have tabs open as a window by using the right clicking option ?
When you close Firefox you should use
*'''Firefox button -> File -> Exit '''
Are you doing that ?
I suspect what may be happening is Firefox is hanging as it closes down.
* see [[Firefox hangs or is not responding - How to fix#w_firefox-hangs-when-you-quit-it]]_firefox-hangs-when-you-quit-it
* this explains how to check & if necessary kill the process [["Firefox is already running but is not responding" error message - How to fix it#w_end-firefox-processes]]_end-firefox-processes
A related possible problem is that you may have built up many copies of the restore files. These are stored in the Firefox profile. The easiest method of finding the profile location istouse
*use '''Firefox button -> Help -> Troubleshooting Information -> [Show Folder]'''
*see [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]
You need to look for the files ''sessionstore.js'' and numbered duplicates of that. Delete them.
* see http://kb.mozillazine.org/Firefox_hangs#Multiple_sessionstore.js_files

When a single-page form expands to more than one page, can you reference the new individual "pages" that have been created by the expanding table?

Don't think this is possible but would love to be wrong.
Bullet Points:
1) In my demo form (simple hierarchy: form1.page1.table1.row1), 8 occurrences (instance "0" through instance "7") of the repeating row1 can be visible
     before it causes a page break and adds another "page". No issues there.
2) I'm thinking about trying to control the end-users navigation abilities to only on-screen "previous page" and "next page" buttons.
     (So no scrolling from page to page; keep them where we want them.) Only way I can see making this work is if the form is designed
     and coded to only allow one page to be visible at a time --- nesting things correctly in a parent object then hide all necessary subforms
     and only make the appropriate subform visible.
3) But when working with tables, when occurrence 9 gets added (aka instance 8), it triggers an on screen "Page 2" to be added.
     End user can now scroll between Page 1 and Page 2.
4) Once Page 2 has been added, is there a way to reference Page 1 (as we see it on screen) and set it to be hidden?
5) Is what we are seeing on screen as "Page 1" and "Page 2" actually this.resolveNode("page1[0]") and this.resolveNode("page1[1]") ?
     Tried messing around with referencing it this way but didn't seem to work. Maybe I had a typo but if we never set the subform named "page1"
     to allow multiple instances, I'm guessing it's not referenced this way.
Any thoughts would be great. Thanks so much to this community.

If you're looking at learning a bit more about database design (looking at your description of what you've done in creating a separate table for each category of item sold sounds like you're approaching it as though it was a flat-file rather than a relational database), there's a few books that I could direct you to:
Beginning Database Design (ISBN 978-1590597699)
Database Design for Mere Mortals (ISBN 978-0201694710)
Databases Demystified (ISBN 978-0072253641)
Absolute Beginner's Guide to Databases (ISBN 978-0789725691)
I've also got an older book that's always sitting by my desk called Dreamweaver MX Databases (ISBN 978-0782141481), which I still reference regularly - chapter 3 on coding practices and chapter 5 on database design provide very good overviews of the subject.
There's also a Database Development for Dummies, but I'm not a huge fan of the series where they're tackling technical subjects.
Without knowing the data you're modeling, it's quite difficult to make generalisations, but I'd probably be looking at a single table called 'Product' (which contains all the product records), and which had in it a boolean for 'new item' and for 'on sale' (you could then use SQL to filter out new and/or sale items when you create your recordset). I'd then have a look up table called 'Categories' which held the values 'necklace', 'handbag', 'belt', and 'purse' which the Product table could then reference to identify.
Breaking your data down into a logical structure like this is called 'normalisation' (see http://en.wikipedia.org/wiki/Database_normalization) - although it's a bit technical. There's a simpler practical explanation of a similar query to yours at TechRepublic (http://articles.techrepublic.com.com/5100-10878_11-5288500.html), which uses MS Access, but don't worry about that as it's teaching a concept which is applicable no matter what the database server.

Insert values from more than one select query

Hi all, I've a simple question:
I need to insert values into a table from two select statements.
There's what I need to accomplish:
I need to monitor the cursors opened on a database, so:
I created the following table:
O_CURSORS
Cols: TOTAL (Number 5), USER (VARCHAR2 20), DATE (TIMESTAMP)
I think some query like the following should work, but unfortunately, it doesn't.
insert into O_CURSORS (total,user,date)
values (
(select a.value, s.username from v$sesstat a, v$statname b, v$session s where a.statistic# = b.statistic# and s.sid=a.sid and b.name = 'session cursor cache count'),
(select sysdate from dual)
)This statement is not working, the message is
"Not enough values"
If I modify the statement as follows, it works fine
insert into O_CURSORS (total,user)
(select a.value, s.username from v$sesstat a, v$statname b, v$session s where a.statistic# = b.statistic# and s.sid=a.sid and b.name = 'session cursor cache count'),
)Any advice would be very appreciated!
Thanks in advance.

You don't have to select sysdate from dual; it can be a part of any select statement. Just include sysdate in your first query:
INSERT INTO O_CURSORS (total,user,date)
SELECT a.value, s.username, SYSDATE
FROM v$sesstat a, v$statname b, v$session s
WHERE a.statistic# = b.statistic#
AND s.sid=a.sid and b.name = 'session cursor cache count'You'll note also that I elimiated the VALUES keyword, and just used a SQL statement to satisfy the INSERT statement.

Thank you.

Thank you Visakh16..
I got solution ..
seq=4 for the record is nothing but sql is partitioning records first and filtering .
If i move the filter inside and working is fine..
SELECT Seq,ParentId,refid,TaskNo,TaskOwner,UpdatedBy,Remarks
FROM
SELECT *,ROW_NUMBER() OVER (PARTITION BY ParentId ORDER BY refid) AS Seq
FROM [t_TaskMaster] WHERE STATUS NOT IN ('Deleted', 'Completed', 'Closed') AND [TaskOwner] = @UserName
AND UpdatedBy <> @UserName
)t
WHERE Seq=1
Filter should be inside only
As ROW_NUMBER logic should be applied only after filtering. otherwise you'll miss required records
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

How to get Airport Express to authenticate the PPPoE connection so that more than one computer can get online

Hello,
I have to use a PPPoe Connection with my ISP and have some troubles setting up the Airport Express. I can only use the Airport in Bridge Mode and DHPC and authenticate the PPPoE on the mac individually. With this solution, no second computer can be set up to use internet at the same time.
I want the Airport Expres to authenticate and pass on "free internet" so that I can connect as many devices as I wish in a normal manner (without PPPoE). However, as soon as I put all the relevant information into the Airport Express, no Internet is coming through anymore. I can connect the computers to the Airport, but there is no interet and the Airport Utility will tell me the same in its settings.
What can I do? A support member in the apple store told me there is no way to authenticate with the Airport Express but could not tell me what the Airport Express' PPPoE setting was there for in the first place. My ISP told me many customers use Airport Express Routers and that there should not be any problem.
I am stuck:(
Thanks for your help in advance

The AirPort Express can support PPPoE regardless of what the Apple Store employee told you.
To configure the Express to do so you will need to use the AirPort Utility:
AirPort Utility > Select the Express > Edit
Internet tab > Connect Using: PPPoE
Enter the appropriate PPPoE information that your ISP has provided you in the fields on this tab.
Click on Update and allow the Express to restart.
The important thing about PPPoE is that only the device that is directly connected to the Internet should be configured of providing the PPPoE credentials, all other devices should be configured for using DHCP. Note: I am assuming that your AirPort Express is the only router in your current network configuration and that it is directly connected to an Internet modem and not another router upstream of it.

Can there be more than one transport targets for a business system in sld

Hi All,
I have a question about transport targets in sld for sap xi 3.0 sp19.
We have a requirement where a business system needs to have two transport targets.In SLD i see that only one transport target can be assigned. Is there any way to assign more than one transport target to a business system?
I know that there can be more than one source for a business system where more than one different business systems have the same business system as the target.
I am not sure if a business system can have more than one transport target .If yes , what is the way to add more than one ?
Please help .
Thanks,
Padmaja

Hello,
I know that there can be more than one source for a business system where more than one different business systems have the same business system as the target.
As far as I know, you would have to change the target everytime you will transport it to a different target e.g 3 target systems = 3 times you change the transport target in SLD.

Mark
