Get all files from Directory

Hi All,
My requirment is to get releted files from Local Directory.
For Example Path is "D/Data/"
in this path there is files like
abc123_de.txt
abc123_en.txt
xyz123_de.txt
abc123_pt.txt
xyz123_en.txt
pqr123_en.txt
bcg234_en.txt
sjd467_en.txt
Now i want to use only files which are strart from abc123 and use their data.
From which FM i can do it or how can i do this?
Thanks,
Mahipalsinh

Dear Mahipalsinh,
I have got the same requirement some days back, i think there is no FM for your requirement. so what i did, i have get all the files using below FM and Concatenate the ABC.
Please use the Below FM, because if the file name is above that 50 character that time always it gives the full file name. Please check, if u used the other one for getting the Files.
   CALL FUNCTION 'EPS2_GET_DIRECTORY_LISTING'

       iv_dir_name            = lv_dir_name

I recently purchased an iMac and used migration assistant to get all files from my emac, but now I have three user accounts. I only want one (perhaps two) accounts. I want all my music, photos and word docs from old computer in one user name

I recently purchased a mac and used a firewire to transfer my files onto my new imac with migration assistant. Now I have 3 users. I want one with all my main files (pictures, music, files from my old computer).
I don't mind having an additional "family" account so my younger daughter can't mess us things, but I can't figure out how to get files from one to the next and then delete the one user name.
Thanks,

In order to delete other accounts you must be logged into an admin account. You cannot delete the account into which you are currently logged.
When you started the new computer you were in the Setup Assistant. You created a new admin account before finishing the setup. You need to log into that account because it is an admin account. You can then delete the account you migrated from the old computer (and any other accounts you don't need or want.)
Then create a temporary new user account with admin status - name it, Temp. Log out of the current account and log into the new account, Temp. Now delete the initial account you created in Setup Assistant. You now have one account, Temp. Now re-migrate your data from the old computer. When that is completed log into the migrated account, which should be an admin account, and delete the temporary account, Temp.

How to get all files from Archive server

Hi Experts,
My problem is:
When i try to read from an archived file, the moment archive_open_for_read function module is executed, a popup box appears
asking to choose the name of the archive file to be read.
I have to pass only one Export Parameter i.e. Archive Object.
How to avoid the popup screen from appearing. I want to read all the archived files by default, the values are to be retrived from the archived files and displayed.
Thanks,
Parthow.

Hi,
I probably didn't understand your question, as I think my answer is exactly what you expect.
In an archive object, you may have 1 or more files. If you want to know the list of files in the object, you have to use ARCHIVOBJECT_GET_TABLE.

I previously had PS CS5 Trial installed but removed it using both Control Panel Programs and deleting all files from the CS5 directory on Program Files. I then installed a purchased product from Adobe disc using the serial number on the case. But when I try to launch it, I get a screen headed Photoshop CS5 Extended Trial. It asks for the serial number and says that my trial has expired. It rejects the serial number from the Adobe case saying "This Serial Number is not valid for this product". It thinks that I still have the expired Trial Version installed. How do I convince it (the program) that the Trial Version is long gone and the currently installed product was installed with a valid and accepted serial number????

Let me know how it goes. Go into your Adobe account and register your serial number asap.

That way, should you lose it or you need support, it is on record that it's yours and you can fetch your s/n it from anywhere.

How can I create a array with all files from a directory

How can I create a array of files or varchar with all files from a directory?

I thought the example could be improved upon. I've posted a solution on my blog that doesn't require writing the directory list to a table. It simply returns it as a nested table of files as a SQL datatype. You can find it here:

How to get a file from an internet site

I have a scenario where I need to get a file from a website.
Basically on a weekly basis one our customers are going to upload a file that contains all the information for delivery's for the coming week.
the way this used to be done is the user would go to the website directly and download the uploaded file.
However now we want to do it as an automatic integration using PI.
Does anyone have an idea how to do this? Is it even possible?

> Thridly my issue with regards to taking a file that is uploaded to a website (it will be a csv file), can be solved by creating a webservice?
I am sorry, I misunderstood this. I thought you want to download.
The upload is done with a HTTP POST, so you can use the HTTP receiver adapter.
Use the prolog and epilog to simulate the form data post.
Use an HTTP sniffer to get the whole HTTP stream, when you upload the file to the website to see, what you have to put in the HTTP adapter settings.
Here are some threads about that topic:
Receiver HTTP Adapter - multipart/form-data file post - SP19

How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system. Not enough memory to upgrade.

How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system. Not enough memory to upgrade.

You can't. iCloud is not for general file backup from a Mac. It's for backup up and syncing data between mobile devices and and Macs and The following is from this Apple document: iCloud: Backup and restore overview.
iCloud automatically backs up the most important data on your (mobile) device using iOS 5 or later. Once you have enabled Backup on your iPhone, iPad, or iPod touch .....
What is backed up
You get unlimited free storage for:
Purchased music, movies, TV shows, apps, and books
Notes: Backup of purchased music is not available in all countries. Backups of purchased movies and TV shows are U.S. only. Previous purchases may not be restored if they are no longer in the iTunes Store, App Store, or iBookstore.
Some previously purchased movies may not be available in iTunes in the Cloud. These movies will indicate that they are not available in iTunes in the Cloud on their product details page in the iTunes Store. Previous purchases may be unavailable if they have been refunded or are no longer available in the iTunes Store, App Store, or iBookstore.
You get 5 GB of free iCloud storage for:
Photos and videos in the Camera Roll
Device settings (for example: Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts)
App data
Home screen and app organization
Messages (iMessage, SMS, and MMS)
Ringtones
Visual Voicemails
But not from a Mac. If you want to backup your photos and other important files I suggest you get an external hard drive and use it with Time Machine.

Is there any way to get the files from other computer ?

Hai all,
I have 2 computers connected. I know the IP address of other computer. Is there any way to get the files from other computer. (for e.g. I want to get the files from specific folder. In Java netwroking is it possible? (Any programs)
regards,
Namanc

Bro Take it easy.
Think you need to send a Image file named ("abc.gif")
now develop a server using ServerSocket and connect it in local IP and any PORT
For example i think ur server is connected in "localhost" and 9000 port.
Now make ur server educated using some commands.
For example:
FileName: <File Name String>
[Means new file is sending by connected client]
FileSize: <File size long or int value>
[ So that ur server can determind about the total length of sender file]
DataModeOpen
[Now your client will send its image data, this command means your client software is sending data]
fjadlkfjaofaijojfwoeiurfodkjflsajlfksa
l23j4lj23lkjlasjfoq23j4rokjelfkjasldkf
2o3j4lk2j3ljslakdjf2l3j4 l23kjlk23k4j
DataModeClose
[Means file sending finished]
Close
[Means your client connection is closed]
Now develop a client supporting this command.
For example(Server):
String getFileName=null;
long getFileSize=0;
public handleCommand(String getCmd) {
    if(getCmd.startsWith("FileName")) {
            String[] splitData=getCmd.split(":");
            this.getFileName=   splitData[1];
            outPutStream.writeBytes("+OK");
    } else if(getCmd.startsWith("FileSize")) {
            String[] splitData=getCmd.split(":");
            this.getFileSize=Long.parseLong(splitData[1]);
            outPutStream.writeBytes("+OK");
    } else if(getCmd.startsWith("DataModeOpen")) {
           //data mode open so receive data
          receiveData();
          outPutStream.writeBytes("+OK");
    } else if(getCmd.startsWith("DataModeClose")) {
          //close client socket
         getClientSocket.close();
}For client:
DataInputStream dataIn=null;
BufferedOutputStream bout=null;
public sendFile(bytes[] getBytes) {
        //if ok found then do other or show error message
    if(sendCmd("FileName:"+getFileName)) {
        if(sendCmd("FileSize:"+getFileSize)) {
            if(sendCmd("DataModeOpen")) {
               bout.write(getBytes);
            } else {
               showError(3);
        } else {
               showError(2);
   } else {
        showError(1);
}i think it will help u
