Hi Dharani,
Using UMEfactory u can do that...
1. create one input field,
2. create one attribute called Uid
3. assign Uid attribute to the input field
4. type the following code in Doinit() method
            String uid = wdContext.currentContextElement().getUid();
     try {
     IUser user = UMFactory.getUserFactory().
     getUserByLogonID(uid);
     String userName = user.getDisplayName();
     } catch (UMException ex) {
      e.toString();
5. after that go to Portal create one iview assign to particular user. then u get into the user details...
thats it

How to get the current user name of the host who is occupying a specific VM?

I'm developing a winform app with c# code to manage Hyper-V. I need to remind someone if he/she would take a VM which has already been occupied by others.
Is there any powershell cmd or WMI interface to get the current user of a specific VM?
Thanks!

Hiya,
from cmd there are quser(Query user) and qwinsta(Query Session)
which should give you that. Don't know how you can incoorperate that in C#, but that should give you something to work with :)

How to get the current user name in Provider hosted app using appOnlyAccessToken

Hi,
Please help me, how to get the HostWeb UserName in Provider Hosted App
i have Provider hosted App, and Anonymous Authentication is enabled on AppWeb, using appOnlyAccessToken
Below code does not return current user who Log in in hostweb, it is returning
SharePoint App (app@sharepoint)
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
clientContext.Load(web.CurrentUser);
clientContext.ExecuteQuery();
clientContext.Web.CurrentUser.LoginName;
Below code gives a blank name when Anonymous Authentication is enabled, if Anonymous Authentication is disabled
app prompts for credentials
HttpContext.Current.User.Identity.Name
Thanks
Ram

Hi,
Since you are using a provider Hosted app if you want to get the current logged in name than do not use AppOnlyAccessToken else use AccessToken which is App + user Context AccessToken.
then
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
clientContext.Load(web.CurrentUser);
clientContext.ExecuteQuery();
clientContext.Web.CurrentUser.LoginName;will return proper user Name.
HttpContext.Current.User.Identity.Name will never return the user as this object is related to IIS server of your App Server not sharepoint.you should set this as Anonymous in case of provider hosted app.you can download the below sample which uses the AccessToken which has user name in it.https://code.msdn.microsoft.com/Working-provider-hosted-8fdf2d95

How can I get the current user and the current page?

Hi everyone
Question..
It is possible to get the current user (from the user's database on apex) and the current page? (I mean, if I'm in page 4 be able to query a variable / function or something which could give me the current displayed page)
Thank you very much... I'd been researching without success :-S so I'll appreciate your help
Regards,
Fury

Fury,
If the user has authenticated, :APP_USER is the name that was used. The current page id is in :APP_PAGE_ID.
Although I showed bind variable notation for those, & substitution format and v() notation are also available for referencing developer-defined items or built-in names. See the User's Guide for more details.

How to get the "current date" in the BEx?

Hi all,
I need to get the "current date" in my Bex report in order to make a comparison. I know there is a "How to" which shows how to get the current date via a User Exit, but I didn't find it. Could you please help me?
Thanks

1. Create a New Formula in Key Figures structure
2. Give tech name and description and Select "New variable" option
3. Next screen will launch Variable Wizard -> create a new variable with replacement path as processing type
4. in next screene select the date characteristic that represents the first date to use in the calculation (From Date)
5. In the next screen select Key in the Replace Variable with field. Leave all the other options as they are
6. In the next Currencies and Units screen select Date as the Dimension ID.
6. Save variable
repeate the Above steps to create another variable (To Date)
and now you can use these two new replacement path variables in your new formula.

How to get the current schema name

Hi,
Can anybody please tell me how to get the current schema name, there is some inbuilt function for this,but i am not getting that. Please help me.
Thanks
Jogesh

ok folks, I found the answer at Tom's as usual.
http://asktom.oracle.com/tkyte/who_called_me/index.html
I rewrote it into a function for kicks. just pass the results of DBMS_UTILITY.FORMAT_CALL_STACK to this function and you will get back the owner of the code making the call as well some extra goodies like the name of the code and the type of code depending on the parameter. This ignores the AUTHID CURRENT_USER issues which muddles the schemaid. Quick question, does the average user always have access to DBMS_UTILITY.FORMAT_CALL_STACK or does this get locked down on some systems?

How to Get the Current Workitem id at runtime

Hi All,
I have a scenario, where request pending with a user who has already resigned the organization. The requirement is that we need to provide a report
of the request and with whom it is pending with along with the workitem id with a forward push button.
So that if the user identifies that a request is pending with someone he can click the record and press for the forward button and a pop-up to be showed where he can enter the userid to whom he needs to forward it.
In this scenario can anyone tell me how to get the current workitem id at run time and to save it to a custom table.
I tried with method before workitem execution, but here i am not getting the current workitem id.
Can you please suggest a good solution for this.
Thanks and Regards,
Balaji

Karri,
I think i can explain you with an example.
Here is my Scenario.
A user has raised a Gate pass and it went to all approval's and got approved and the material is also sent out from the plant. Lets take the date as 1.1.2013 (A Warehouse person have done the checking and sent out of the plant).
On 1.3.2013 some of the material has been returned and a material inward request has been raised and now the warehouse person has to do a inward checking and to sent it back for the initiator for the approval, but the warehouse person has resigned the organization on 1.2.2013, now the workitem is pending with the warehouse person who has already resigned.
My scenario is once the material inward request is created and before the workitem is delivered to the warehouse person i need to get the workitem id and to store the workitem some where.
So that in future if any warehouse dept head wants to forward the workitem which are lying in the person inbox who has already resigned he can do it via a report using this workitem id.
So, can anyone help how to get the dialog workitem id before the workitem creation or execution. I tried with "method before workitem execution" but my break point is not triggering at this point.
Thanks and Regards,
Balaji

How to get the current path of my application in java ?

how to get the current path of my application in java ?
thanks

To get the path where your application has been installed you have to do the following:
have a class called "what_ever" in the folder.
then you do a litte:
String path=
what_ever.class.getRessource("what_ever.class").toString()
That get you a string like:
file:/C:/Program Files/Cool_program/what_ever.class
Then you process the result a little to remove anything you don't want:
path=path.substring(path.indexOf('/')+1),path.lastIndexOf('/'))
//Might be a little error here but you should find out //quickly if it's the case
And here you go, you have a nice
C:/Program Files/Cool_program
which is the path to your application.

How to get the current page URL

HI All
I am working in oracle apps 4.0
I have one page called history in that i have one page item called Application url. My application id is 122 but its a copy of application 106
How to get the current page url for the page item.
Any steps should be help ful
Thanks & Regards
Srikkanth.M

I'm not 100% clear on what the requirement is from the description, however it does sound like you are making things unnecessarily complicated.
If you want permanent/ID-independent links then use application and page aliases.
so here we used to display the url like this: <tt>{noformat}http://81.131.254.171:8080/apex/f?p=122{noformat}</tt>
Do you mean that the URL is displayed like that? If so that doesn't seem particularly helpful. How is anyone supposed to know what it is?
There are many ways to provide links in APEX—including lists and nav bars.
Where the link is to another resource located on the same server (such as another page in the same app, or a different app in the workspace), relative addressing can be used, making it unecessary to include scheme, domain and port information in the URL. For example, if the page to be linked to has a page alias <tt>ABOUT</tt> in an application with alias <tt>UNITY</tt>, and the apps share an authentication scheme/cookie to permit shared sessions, then the link URL is simply
f?p=UNITY:ABOUT:&APP_SESSION.
