File path selected by the user!!! (File Download)

Hi,
Does exist a component, code line or any thing which emulate the Windows option SAVE AS: when the user does right click, but using a button to do this?
If somebody knows? I will appreciate it.
Thanks in advance!!!

Thanks for your information!!! I found this post Re: Looking for example to export data from a DynPro table to Excel file which has code lines to export data from a Web Dynpro table to Excel file, it is saved perfectly in the local machine and save it in the server won't be problem.
Your recomendation about the post it is to provide a popup window to change the name and extension of the file, how can I make it? ... Is there an UI Element in NWDS?

Dear Expert,
I have one requirement like to read the selected workset name in portal by the current user.I have read two documents regarding how to retrieve the PCD contents (iViews, Pages, Worksets and Roles) and its properties like Created by, Changed by, Last changed by and others using PCD API.

But I am not able to understand how to get the specific name of the workset which is currently selected by the user.Can you please help me.
I am using portal 7.0.
Thanks & Regards,

Hi Expert,
I found that we can use Interface INavigationHelperService to read Portal Role selected by user at runtime from http://scn.sap.com/thread/52194
But this class is available in SAP NetWeaver 7.30 Enterprise Portal .
But in SAP NetWeaver 7.0 Enterprise Portal that interface is not available.
INavigationService is available there.
But didn't get any proper discussion on this interface for the same requirement.
Can you please help me.

Browse the File path selection in the selection screen

I want to give the user the option to browse his/her desktop and selct a file path and windows name by clicking on a drop down.
How do I do that?
Thank you in advance

hi ,
there are so many function modules which will provide F4 Help for the path.
Suppose you have given a parameter name path.
You have to use these FMs in the event
AT SELECTION-SCREEN ON VALUE-REQUEST FOR path.
Example :
data : C_FNH_MASK TYPE DXFIELDS-FILEMASK VALUE '.',
SEARCH_DIR TYPE DXFIELDS-LONGPATH VALUE '/SAPGLOBAL/USERS',
      FILE_PATH LIKE DXFIELDS-LONGPATH.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR path.
CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
    EXPORTING
      I_LOCATION_FLAG = 'P'
      I_SERVER        = ' '
      I_PATH          = SEARCH_DIR
      FILEMASK        = C_FNH_MASK
      FILEOPERATION   = 'R'
    IMPORTING
      O_PATH          = PATH
    EXCEPTIONS
      RFC_ERROR       = 1
      OTHERS          = 2.
CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
    EXPORTING
      I_LOCATION_FLAG = 'A'
      I_SERVER        = ' '
      I_PATH          = SEARCH_DIR
      FILEMASK        = C_FNH_MASK
      FILEOPERATION   = 'R'
    IMPORTING
      O_PATH          = FILE_PATH
    EXCEPTIONS
      RFC_ERROR       = 1
      OTHERS          = 2.
If you remove 'P' and put 'A', then it is used for application server F4 help.
you have F4_FILENAMEand F4_FILENAME_SERVER for presentation and application servers respectively
Reward points if helpful.

Report to show Service Requests that are open on a day selected by the user

Dunno if I'm being thick, but I can't see how to do this in a report/dashboard...
The user selects a day and the report pulls back all the Service Requests that were open on that day using the following logic...
Service Request Opened Date <= Selected date & Service Request Closed Date >= Selected date
Is this possible?

You can do this with a report or a dashboard.
For a report, create a report your subject ares, like Service Request. In Step 3, Create a prompt on your date and choose Column Filter Prompt. Give the prompt a caption ("Enter/Choose Date" for example). Choose the date field for the Filter on Column. Determine how you want the users to select the value and hit OK. My experience has been that you need to let users type in the date, as opposed to choosing from a drop-down list, because of the volume of data and performance reasons, but test it to determine what works best for your needs.
For a dashboard, you would need to create a dashboard prompt for your dashboard report. You do this by creating a new report on your intended subject area, i.e. Service Request. Instead of creating the report as you normally do, you need to click on the Create Dashboard Prompt button at the top left, just below the Oracle logo. Choose the right reporting area, then complete the prompt details. Don't forget to allow for the prompt in your report.
I always recommend that you consider purchasing a great book on reporting, written by Mike Lairson. It is an excellent resource for nearly all of your reporting questions. You can find it on amazon.com.

How do I create a specific packages for users where in only the admin has the access of which software the user can download?

Is there any possibilities that the admin of the team can limit the packages of the user? Only the admin can add and remove software to be downloaded for specific users.

You can include single app plans in team packages, but otherwise no. This will exclusively depend on the users' local permissions on the computer - if the can install one app, they can install all of them, be it only as a trial.

How to code a button to enable the user to download music?

How do I get my application to continue processing instead of waiting for a menu selection when the user clicks on a drop-down menu?

I'm developing a process-control application,using serial communication for data acquisition. My problem - I need this serial read of data to be continuous. But, when I click on a drop-down menu, the rest of the processing halts until I click on one of the menu items in the drop-down list and I lose data in that interval. What can I do?

In most process-control applications it is not about just avoiding lost measurement data. The most important is having a robust control-algoritm that reacts to a change of input-situation in a given time.
A non-responsive system is not a very reliable process-control solution.
The vi you mentioned are only around since the latest versions and the old method of polling controls still suits many applications (but that's another discussion).
As about RS-232 input time-outs, I have never used that.
In the time before VISA was created I (as other LabVIEW users I discovered) used a method of storing every incoming string in a buffer (memory-vi with USR) and that still works (classic serial VI's versus VISA is also another never-ending discussio
n).

"File Dialog" Express VI returns the wrong path when the user selects the desktop

In labview 8.0.1 with Windows
XP, the File Dialog Express VI seems to return something other than the path
selected by the user when configured to browse for folders (or files and
folders) and the user selects the desktop.
I can't determine exactly when it works and when it fails, but it always seems
to fail if the user selects the desktop from the places bar (the shortcuts on
the left side of the dialog) or from the drop-down menu at the top of the
dialog and then clicks the "Current Folder" button to dismiss the
dialog. In this case it always returns whatever path is wired to the
"Start Path" terminal.
If the user navigates to the desktop with the "Up One Level" button
or by selecting the actual desktop directory under Documents and Settings, the
correct path is returned.
If the user selects a file before clicking the desktop icon, then clicks
"Current Folder" the correct path is returned.
If the user clicks the desktop icon, clicks open, then clicks "Current
Folder" the correct path is returned.
It's possible to work around this bug in most cases by setting the start path
to the desktop.
Has anyone seen this behavior before?
Can anybody verify this behavior by running the attached VI?
In the past, when I've reported issues like this I've received responses from
NI engineers that basically said "Thanks, but we already knew
that". Is there anywhere that users can search the list of known
bugs and avoid wasting time tracking down issues that are already understood by
NI?
Thanks,
Adam Brewster

File Dialog Test.vi ‏39 KB

I'm on 8.2 and I can't get it to fail no matter how I select the desktop. I haven't tried it in 8.0, but I imagine that if this really is a bug, they did know about it and fixed it with 8.2. If this causes a real problem for you, I would suggest upgrading if you can.

File download from the server

I have this page(in a distributive application) that checks the status of files on the server. These are hyperlinked and I am trying to allow the users to download the files. I can see the files, and the links but can't download a file or "save target as.." option.
I have added an .xml file in the configuration directory of my application server(JBoss). I can download the files on the same computer, but if I can't do that from other computer. I got this .xml file from online search, someone suggested to use this in order to allow for download option.
<?xml version='1.0' encoding='utf-8'?>

Thanks.

How to check the status of file downloading?

I have to download the selected file by using "file download" dialogue box.
This "File Download" dialogue box provides options for "Open", "Save", "Cancel" or "More Info". It is similar to usual "File Downloading".
And i am required to do further processing only if , file is "Open" or "Save".
So how can i check the status of the option selected by the user?
Following is the code snippet:
res.setContentType("text/plain");
res.addHeader("Content-Disposition", "attachment; filename=" +value);
try
     uFile= new File(fPath);
     fSize=(int)uFile.length();
     fis = new FileInputStream(uFile);
     c=-1;
     while ((c = fis.read()) != -1)
          out.print((char)c);
     fis.close();
     out.flush();
     out=null;
catch(Exception e)
       out.println("Exception : " +e);
} I tried to generate a flag and inside a while loop, and then checking the status of that flag outside of loop.
But it doesn't work.
It reflects the value of flag even if user selects "Cancel" Option.
So, if there is any another way of checking the option selected by user from "Open","Save" or" Cancel", then please reply me.
Thanks in advance.

Is there any solution for this or any web link for this...?

ls_headings-werks = text-003. " Plant
ls_headings-verid = text-004. " Production Version
ls_headings-adatu = text-005. " Valid From Date
ls_headings-bdatu = text-006. " Valid To Date
ls_headings-mdv01 = text-007. " Production Line
ls_headings-ktext = text-008. " Production Line Description
ls_headings-pltyg = text-009. " Rate Routing Task List Type
ls_headings-plnng = text-010. " Rate Routing Group
ls_headings-alnag = text-011. " Group Counter
ls_headings-bmsch = text-012. " Base Quantity

Multiple file download

I'm using FileReference.download() to download a single file from a server to a local machine.
The download() function opens a dialog box where the user select where he wants to save the file and what name give to it.
Is it possible to download X files in sequence without calling X FileReference.download() and so X dialogs open?
A single download() with more files?
Multiple download() but without the dialog box?

i doubt it, if that was possible it would provide a major security hole that could be exploited.
I developed a FTP application in flex for a client a while back, and that's when i did most of my searching around to see if this was possible, and couldn't turn up anything apart from people saying it wasn't possible.
I'd be very interested to hear if someone say it is, but until then i believe the only way to accomplish something like this is like a said, a server side script to handle all selected file references for download, zip them up and then allowed the user to download that zip file.
I imagine, it might be possible in AIR (considering that has far greater access to the local machine), but as far as a flex app goes, i'm pretty confident to say it's not possible.
let me know if you find out otherwise though.

Create file downloadable from browser?

I'm looking for any help (code examples too) on how to create a file that the user can download to a location of their choice.

This is all being done on an intranet. Thanks!
