Howto get the list of all streams?

Greetings!
Newbie here. Be kind. I am reading the PDF Reference but not finished of course.
I would like to know if there is a way once you programmatically open the PDF file to know how many stream object there are in the PDF short of scanning the file from top to bottom?
Thank you for help, its appreciated.

Hi IroSenth,
You're right of course. I should go look at the end in the xRef cross reference table first.
But this would lead me to more tables and streams and going down that rabbit hole I will leave for a fresh monday morning...
Really, I am learning to program after not doing that for 10 years....
I wrote so far a nice little C# UI that displays in a textbox what it can from the PDF source as I cast the bytes into a unicode array.
The purpose is simply to let me look at it, know where the cursor (offset) is and so forth : its an exploratory tool, a glorified version of notepad that I can use to display specific ranges of the pdf, albeit unicode encoded.
The streams is where the textbox in my little app encounter (most probably) illegal character combinations since the output always cuts off in the midle of the stream. Hence I convert the stream to 1's and 0's display them as such in the textbox.
I'll have to implement FlateDecode next week (ouch!!! (for a newbie )...
In a nutshell, I wanted to know how many things were encoded in the file.
How many stream ... endstream there were in there.
Thanks for your time, its really appreciated.
Sincerely,
Antoine

How can i get the list of all users present in the LDAP

Hi Experts,
How can i get the list of all users present in the LDAP ?
Is there any API or function Code to get all user list??
Please help me out!!!
Help will be rewarded

Well it will depend on exactly where your UME configuration points to in the LDAP tree but yes, it is possible to get all users. Something like the following should do it:
import com.sap.security.api.*;
import com.sapportals.portal.prt.component.*;
IUserFactory iuf;
ISearchResult isr;
IUser user
String userid;
iuf = UMFactory.getUserFactory();
isr = iuf.getUniqueIDs();
you will need to iterate the ISearchResult object but you can get IUser objects by
userid = (String)isr.next();
user = iuf.getUser(userid);
then you can imanipulate / identify / or whatever you need with the user object

Hi Pankaj,
find the official NetWeaver security javadocs (including access to UME) <a href="http://help.sap.com/javadocs/NW04S/current/se/index.html">here</a>. Look for classs UMFactory and proceed from there.

How to get the list of all formtypes in SBO?

Hello,
How can i get the list of all available formtype in SBO?
Each SAP Business One form has a unique type to support multiple instances of the same form. For example, the type of the Purchase Order form is 142, Form=139 for Sales Order.
Is this information stored anywhere?
Thanks and Regards,
Sheetal

Hi Juha / Sheetal,
Activating the menus will only help to get the forms which are "directly" accessible...
...but there are forms that come up only when clicking some button - or double-clicking - or activating a menu item in the (dynamic!) "Goto" menu etc.
In 2005 SP01 a new function was introduced (and documented in the SDK Helpcenter) that can be used to iterate over all integer IDs (note there are a lot of gaps) up to 65535 and get information about the form and items on it (specifically the databinding!).
Please take a look at the ResourceData property of the Application object in UI API!
Gaps (in A version today - to my best knowledge): 10.000 - 20.000; 21.000 - 40.000; 41.000 - 50.000; 51.000 - 60.000...
Regards,
Frank
<i>Visit the WiKi-FAQ at: https://wiki.sdn.sap.com/wiki/display/HOME/BusinessOneFAQ</i>
BTW: What do you need that information on "all forms" for?

How to get the list of all users

Hi,
Is there a way in Grid Control for getting the list of all users on all target databases? I need to count how many Oracle db users in our company.
Thanks a lot.

One way to do it might be...
Assuming you have preferred credentials set up for all of your databases, you could run a 'select username from dba_users or all_users;' against all of your databases through grid control.
Click on Targets tab, click Databases, then the 'Execute SQL' link at the bottom of the page. Click 'Add' and 'Select All'. Then run it. It's just running the same sql across all of your databases and the output will be at the bottom for all of them.

Can we get the list of all BO report scheduled to be sent(or have been sent) for a specified day?

Hi all,
For all BO reports scheduled to be sent out, can we get the list of all BO report to be sent(or have been sent) for a specified day?(For example, today or nex Monday). Thank you.
Regards,
Eton.

Hi Eton,
To check the instances which have ran today, you can use the below query in query builder.
SELECT SI_NAME,SI_ID FROM CI_INFOOBJECTS WHERE SI_INSTANCE=1 AND SI_STARTTIME > '2014.08.20 00:00:00' Order by SI_STARTTIME DESC
To check the instances which would be running in the future, that means you have recurring schedules. Check for the SI_NEXTRUNTIME to get the details of instances which will run in the future as per the recurrences.
Thanks,
Prithvi

Need to get the list of all procedures called in an object

Hi,
I am trying to find the list of all proceudres called in an object. I can get the list of packages and individual procedures/functions using dba_dependencies, all_dependencies or user_dependencies. However this would not give me the list of procedures of a package that are used in my object.
How to find the procedures of a package (and not just the package name) being called in another object?
Thanks in advance
Upendra

You can take the package name from user_depencies and query the USER_SOURCE table for the object name where the package name exists.
Eg code, here PKemp is the package name.
SELECT SUBSTR(TEXT,INSTR(TEXT,'PKEMP'))
FROM USER_SOURCE
WHERE NAME = 'PROCEMP'
AND INSTR(TEXT,'PKEMP') >=1
SUBSTR(TEXT,INSTR(TEXT,'PKEMP'))
PKEMP.SALUP;

To get the list of all session-id-owner

Hello from Vienna,
It is about a website, the user, who is already logged in, has a session-id.
a) How can i get all the list of the users, who currently have a session-id ?
b) How can i list the current session-ids (which still are active)
That ist a question of an exam.
many thanks

You can store every session id (or token) in a data base. When user logs in You simply assign the user with token and save this token into data base, the token of course has a "valid thru" field. Then when You need to list the users You make a query that gets the users with tokens that are still valid.
I don't know if this can be done plainly on the servlet side.
