Dynamicall create csv files and zip them

Apex version - 4.2
I have some data in the database. I want to generate multiple csv files dynamically from those data. Then zip the csv files together to provide it to the end user.
Can anybody suggest with the approach that could be followed.
Thanx in advance !

Find some code to generate the csv, for instance Export and save result set in CSV format using UTL_FILE
Find some code to zip the files/blobs, for instance http://technology.amis.nl/2010/06/09/parsing-a-microsoft-word-docx-and-unzip-zipfiles-with-plsql/
Combine the two pieces
Done

I am having problems creating PDF file and downloading them

I am having problems creating PDF file and downloading them

Hi Randy Keil,
You might need to sign up with your Adobe ID and password at "https://cloud.acrobat.com/convertpdf"
Then you can choose the desired files to create the PDF.
Now, let me know what error message do you get while doing the same.
What kind of files are you trying to convert to PDF?
Have you checked with your internet connection and tried using a different browser?
Hope to get your response.

Function moduls to create csv-file and send it per mail

Hello,
we have the following requirement.
We created an eventhandler.
Inside this eventhandler we built up an internal table with 1-n entries.
Now we want to create a csv-file or excel-file in background and send it to the users mailadress.
Are there standard function modules which we can use for this requirement.
We can´t download the file directly to the users client with cl_gui_frontend_services because we are not in SAP GUI but in CRM Webclient UI.
Thank you
Best regards
Manfred

hello,
thank you.
a coding example would be very helpfull.
the internal table shall be added as csv-attachment to the mail and the recipient shall be the current user.
Thanks a lot in advance.
Kind regards

Uploading csv files and reading them from server

I want to read a csv file.From Flex i am able to select the
file but when i pass it to the server using struts
FileUploadInterceptor , am not able to pass the file to the
server.FileUploadInterceptor in struts2 processes the request only
if its instance of MultiPartRequestWrapper.Is there any way in Flex
where i can pass the request as a instance of this.Is there any
other way in which i can read the file from the server after
uploading it through flex.Code is as follows :

Powershell script to update a field value (recursively) in sharepoint form a .CSV file and not changing the updated by value

need to run through a list of old to new data (.csv) file and change them in a sharepoint list - can not make it work
here is my base attempt.
$web = Get-SPWeb site url
$list = $web.lists["List Name"]
$item = $list.items.getitembyid(select from the items.csv old)
$modifiedBy = $item["Editor"]
#Editor is the internal name of the Modified By column
$item["old"] = "new from the .csv file parsed by power sehll
$ite.Syste,Update($false);
$web.Dispose()

Hi,
According to your description, my understanding is that you want to update SharePoint field value from a CSV file recursively.
We can import CSV file using the Import-CSV –path command, then update the field value in the foreach loop.
Here is a code snippet for your reference:
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
$csvVariable= Import-CSV -path "http://sp2010.contoso.com/finance/"
# Destination site collection
$WebURL = "http://sp2010.contoso.com/sites/Utility/"
# Destination list name
$listName = "Inventory"
#Get the SPWeb object and save it to a variable
$web = Get-SPWeb -identity $WebURL
#Get the SPList object to retrieve the list
$list = $web.Lists[$listName]
#Get all items in this list and save them to a variable
$items = $list.items
#loop through csv file
foreach($row in $csvVariable)
#loop through SharePoint list
foreach($item in $items)
$item["ID #"]=$row."ID #"
$item.Update()
$web.Dispose()
Here are some detailed articles for your reference:

Creating an XLS file and Zip it

Hi All,
we have a requirement where in we have to create an XLS file from internal table. This xls file then has to be zipped and mailed.
If anyone knows how to create an xls file and zip it in WebDynpro, without using OPEN, CLOSE DATA SET etc, Please let us know. It will be of great help.
Thanks,
Anand

>2) Convert the STRING format to XSTRING format by using the FM SCMS_STRING_TO_XSTRING.
Actually you should use CL_BCS_CONVERT=>STRING_TO_XSTRING now.
>3) Use the method COMPRESS_BINARY of class CL_ABAP_GZIP to compress the XSTRING file.
You probably want to use CL_ABAP_ZIP instead of CL_ABAP_GZIP. CL_ABAP_GZIP only does compression, which is fine for storing a single packet of data in the database. However CL_ABAP_ZIP is better suited for mult-part zip (multiple inner files).
>4) Use the method SEND_WEB_MAIL of class CL_HRRCF_SERVICES_MAIL to mail across the zipped contents.
This seems to be an HR specific class. Better to use the cross application, NetWeaver provided functionality for sending mail - CL_BCS.

Create a csv file and send it in an email

In coldfusion, is it possible to create a csv file and send it in an email, without ever saving that file on the hard drive?

Yes, you can create an email attachment without writing a file to disk. This feature was introduced in CF 8.0.1.
I've posted a sample to a previous thread on the forums.
http://forums.adobe.com/message/2123297
See the CFMAILPARAM section of CF 8.0.1 release notes for attachments without a file on disk.

Automator: Create new folders from .csv file and put images inside.

I have a challenging Automator task to achieve. I need to
1) create a set of folders labeled with the contents in column A of a csv file. (example: column A1 JoeBrown A2 SuzyBrown A3 JimBrown etc..) resulting in
3 folders titled JoeBrown, SuzyBrown, and JimBrown
2) take the image represented by an image number in column B of the same csv file and move that file into the folder that was created (example: A1 JoeBrown gets a folder created by the name JoBrown and column B IMG_1234.jpg is physically moved from within the same folder as the .csv file into the folder created by column A.
Both the csv and img files would be in the same folder. I have the script to create a set of folders from a csv list just can't complete the moving of files based on the contents of column B.
SUMMARY: I have a folder containing several images img_0001, img_0002, img_0003 etc. and a csv file that contains columnA a series of names and column B a series of jpg image numbers. I need to have a script that will create folders labeled whatever name is in column A (see the script below. it works great!) then move the images from column B to the folders generated from column A.
The csv script is:
tell application "Finder"
set mgFolder to container of mgCSVfile as string
repeat with x from 1 to count paragraphs of mgList
    set text item delimiters of AppleScript to ","
    set mgThisList to text items of paragraph x of mgList as list
    set text item delimiters of AppleScript to ""
    set mgTopFolder to item 1 of mgThisList
    if (exists folder mgTopFolder of folder mgFolder) is false then
      make new folder at mgFolder with properties {name:mgTopFolder}
    end if
    set mgNewFolder to (folder mgTopFolder of folder mgFolder) as alias
    repeat with i from 2 to count mgThisList
      if item i of mgThisList is not "" then
        set mgSubFolder to item i of mgThisList
        if (exists folder mgSubFolder of folder mgNewFolder) is false then
          make new folder at mgNewFolder with properties {name:mgSubFolder}
        end if
      end if
    end repeat
end repeat
end tell
Thanks for any help that may come my way.

This should work
(assumes a true "," seperated file with only two items per line, i.e.: Test,Test.jpg):
The Run Shell Script Action is:
cd "${1%/*}"
while read line

     ImageName=${line#*,}
     mkdir "$FolderName"
     mv "$ImageName" "$FolderName"
done < "$1"

Is there a way to select a certain box of elements from a csv file and read that into LabVIEW?

Hello all, I was wondering if there was a way to select only a certain "box" of elements from a .csv file in LabVIEW? I have LabVIEW 2011 and my main goal is to take two arrays and graph them against each other. I can import the .csv file just fine and separate each row and each column to be its own, but say I have an 8X8 but want to graph the middle 4X5 or something like that. Is there any way to extract an array without starting at the beginning and without ending at the end? Thank you in advance.
Solved!
Go to Solution.

Hi Szklanam,
as a CSV file is just a TXT file with a different suffix you can read a certain number of lines of that file. So you can limit the number of rows in your resultung array. To limit the number of columns you still have to use ArraySubset, so maybe it's a lot easier to read the full CSV file and pick the interesting spots with ArraySubset...

How do I process multiple files and turn them from raw to jpeg

How do I process multiple files and turn them from raw to jpeg. Ive tried and it seems to go through the files but doesnt seem to process them or store them in the selected folder

Yes that was the first thing I did. Then I used the process multiple files and selected a new folder to put them in and selected use open files and selected to turn them into jpeg. The images flash on the screen like they are being processed, but the folder never appears in library. Is it possible because there are a couple 16 bit files open that this corrupts the task. Do I need to create the folder first. Will elements not create the folder on its own.
Thanks Vince

How to configure sync rules involving a CSV file and portal self service

Hello,
I need to configure some FIM sync rules for the following scenario:
User account details are entered from a HR CSV file and exported to AD Users have the ability to modify their own AD attributes in the
FIM portal (there is not a requirement for them to view their HR CSV data in the portal). The FIM portal modifications will be exported to AD as expected.
My setup is as follows:
CSV file - name, last name, employee ID, address.
CSV MA - has direct attribute flows configured in the MA between the data source and MV Portal self service attributes –
users can edit mobile, display name and photo
I've also set the CSV MA as precedent for the attributes
FIM MA – attribute flows defined for MV to Data Source as usual (i.e. firstname to firstname, accountname to accountname, etc).
AD MA – no attribute flows defined as inbound and outbound sync rules have been configured in the portal using the Set\MPR\Triple.
I’m thinking of using the following run profiles:
CSV MA – full import and delta sync (imports HR data)
FIM MA – export and delta import (imports portal changes)
FIM MA – delta sync (syncs any portal changes)
AD MA – export and delta import
If my understanding is correct this should sync HR data from CSV to AD, as well as user attribute self service updates from the portal to AD.
If I wanted to just do a HR CSV sync could I get away with just steps 1 & 4 ? (presumably not as my rules are in the FIM portal?)
If I wanted to do just a portal sync, could I get away steps 2-4?
Any advice on how to improve my setup is much appreciated - cheers
IT Support/Everything

The truth is that your design should be done in the way that it doesn't matter which profiles in which order you will execute. At the end, if you will run all import, synch and export profiles on each data source you should get same result. This is beauty
of synch engine here.
Your steps from 1-4 will synch data to your data sources and at the end will give you expected result. But not because of the order you are executing them but because of correct attribute flows. If flows from CSV file and from FIM portal might be done for
the same attributes you need to think also about attribute precedence.

Not certain this is what you're after, but this :
#import the contents of both csv files
$dbexcel=import-csv c:\dbexcel.csv
$liveexcel=import-csv C:\liveexcel.csv
#prepare the output csv and create the headers
$outputexcel="c:\outputexcel.csv"
$outputline="Name,Connection Status,Version,DbExcel,LiveExcel"
$outputline | out-file $outputexcel
#Loop through each record based on the number of records (assuming equal number in both files)
for ($i=0; $i -le $dbexcel.Length-1;$i++)
# Assign the yes / null values to equal the word equivalent
if ($dbexcel.isavail[$i] -eq "yes") {$dbavail="Available"} else {$dbavail="Unavailable"}
if ($liveexcel.isavail[$i] -eq "yes") {$liveavail="Available"} else {$liveavail="Unavailable"}
#create the live of csv content from the two input csv files
$outputline=$dbexcel.name[$i] + "," + $liveexcel.'connection status'[$i] + "," + $dbexcel.version[$i] + "," + $dbavail + "," + $liveavail
#output that line to the csv file
$outputline | out-file $outputexcel -Append
should do what you're looking for, or give you enough to edit it to your exact need.
I've assumed that the dbexcel.csv and liveexcel.csv files live in the root of c:\ for this, that they include the header information, and that the outputexcel.csv file will be saved to the same place (including headers).

Loading a CSV file and accessing the variables

Hi guys,
I'm new to AS3 and dealt with AS2 before (just getting the grasp when the change it).
Is it possible in AS3 to load an excel .csv file into Flash using the URLLoader (or ???) and the data as variables?
I can get the .csv to load and trace the values (cell1,cell2,cell3....) but I'm not sure how to collect the data and place it into variables.
Can I just create an array and access it like so.... myArray[0], myArray[1]? If so, I'm not sure why it's not working.
I must be on the completely wrong path. Here's what I have so far....
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, dataLoaded);
var request:URLRequest = new URLRequest("population.csv");
loader.load(request);
function dataLoaded(evt:Event):void {
var myData:Array = new Array(loader.data);
trace(myData[i]);
Thanks for any help,
Sky

just load your csv file and use the flash string methods to allocate those values to an array:
var myDate:Array = loader.data.split(",");

Read from csv file and plot particular columns

Hello,
I`m a new user of Labview and here it comes...my first major problem.
Maybe this has been discussed before. I’ve made a search to solve my problem first but I couldn`t find anything helpful so I `ve decided to post a new message.
So here is my problem:
I`m working in a small semiconductor lab where different types of nitrides are grown using proprietary reactor. The goal is to read the collected csv files from each growth in Labview and plot the acquired data in appropriate graphs.
I have a bunch of csv files and I have to make a Labview program to read them.
The first part of my project I`ve decided to be displaying the csv file (growth log file) under labview (which I think works fine).
The second one is to be able to plot particular columns from the recipe in graphs in Labview (that one actually gives me a lot of trouble):
1. Timestamp vs Temperature /columns B and D/
2. Timestamp vs Gas flow /columns L to S/
3. Timestamp vs Pressure /columns E,K,T,U,V/
I`ve got one more problem. How can I convert the Timestamp shown in csv file to human readable date in labview? This actually is a big problem, because the timestamp is my x axis and I want to know at what time a particular process took place and I also want to be able to see the converted timestamp when displaying csv file at first. I`ve read a lot about time stamping in excel and timestamp in labview but I`m still confused how to convert it in my case.
I don`t have problems displaying csv file under Labview. My problems are with the timestamp and the graphs.
Sorry for my awful English. I hope you can understand my problems since English is not my mother language.
Please find the attached files.
If you have any ideas or suggestions I`ll be more than happy to discuss them.
Thank you in advance.
Have a nice day!

Cannot create PS file and PDF in Framemaker 9

I'm using Version 9.0p196.
When I used the "Advanced Save" to save an .fm file to a pdf, I got the message "The specified printer 'N/A' cannot be found, use printer 'Adobe PDF' instead. After I click OK, it said "cannot create PS file", and "failed to create PDF file.
It worked fine before.This problem was occurred after I copied some fonts to the following locations:
C:\Windows\Fonts
and
C:\Program Files\Adobe\FrameMaker9\fminit\fonts\adobe
Those fonts are:
timesbd.ttf
times.ttf
HelveticaWorld-Regular.ttf
HelveticaWorld-Italic.ttf
HelveticaWorld-BoldItalic.ttf
HelveticaWorld-Bold.ttf
I have no idea if that's the cause of the problem. Does anyone know?
By the way, the FM 9 is running on XP.
Thanks,
Meggie

Meggie,
You may or may not have created a mess with fonts. I would try not to have duplicate fonts, it is totally sufficient to have them in C:\Windows\Fonts.
But your FrameMaker verson is definitely four (4) patches behind. The current version is 9.0.4 (9.0p255) and you can get the updaters here:
http://www.adobe.com/support/downloads/product.jsp?product=22&platform=Windows
You have to install them one after another.
Some of the patches improved the Save as PDF feature.
For further communication, please add your OS version and Acrobat version.
