Generate file names randomly

are there anyways to generate file names randomly? if there are, are there any reference codes i could refer to? thanks.
heard that using random characters from ascii code (generating random numbers and translating them into chars) could do the job but i am rather new to it. can anybody advise me on how to go about it? thanks.

There is a method called createTempFile in the java.io.File class for this purpose. I suggest you use that one.

Filespaces in generated file names - unfortunate

I'm trying to upload all the files generated by an export to directory. Many of the auto-generated file names use the name of a page (which is displayed in the navigation - so i don't want to remove the spaces).
This creates files with blanks in the name, and most FTP implementations will choke on this.
#1 - this should be fixed
#2 - does anyone have a workaround for managing this?

Spaces are not valid in web pages. If used, they have to be escaped with %20
If you want to change the names of files before trying to use them with some web publishing program, this shell script might be of use. It changes spaces to _ makes upper case letters lower case, etc.
#!/bin/bash
# Pete keeps giving me photos with bad file names
for i in *
do
OLDNAME="$i"
NEWNAME=`echo "$i" | tr ' ' '_' | tr A-Z a-z | sed s/-/-/g`
if [ "$NEWNAME" != "$OLDNAME" ]
then
TMPNAME="$i"_TMP
echo ""
mv -v -- "$OLDNAME" "$TMPNAME"
mv -v -- "$TMPNAME" "$NEWNAME"

When someone other than myself downloads an image from my web album, a dynamically generated file name replaces the original file name. How I can prevent the original file name being replaced during the downloading process?

When someone other than myself downloads an image from my web album, a dynamically generated file name replaces the original file name. How I can prevent the file name being changed during this downloading process?

Hi Glenyse,
Here are my steps.
1. I upload multiple image (jpg) files onto my photo album.
2. I select the "sharing" by email option for this album.
3. I enter the recipient's email address.
4. The recipient receives my message and clicks on the link.
5. The recipient accesses my photo album and clicks on one of the images.
6. The image opens up to its own screen.
7. The recipient selects the "download" and then save file option.
Here is the part I do not understand. For some reason, during this "download" process, the original name which I have given to the file is replaced by different name. So I was hoping that someone knows how to prevent the file name from being changed during the "download and save" process.
Much appreciated if you can help me find a solution to this problem.

How to generate file name dynamically in receiver FIle adapter? Please help

Dear Experts,
   I have a scenario where I need to generate output file with the name dynamically pulled from the XI payload.
   In receiver File communication channel I don't see any option where we can specify the XML path for the file name.
   For example:
   If my inbound XML structure (inbound interface) is like below:
   <filename>file123.txt</filename>
   <RootNode>
         <Element1>Product123</Element1>
   <RootNode>
From this I need to pick the filename value and generate the output file with the same value.
How can I achieve this? Please help!
Thanks & Regards
Gopal

Gopal,
You can use DynamicConfiguration class for this.
You need to write UDF for this and with input of filename you want to set and map this UDF to the top level node.
Refer the below famous blog from Micheal:
/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
You can also use Variable substitution to get value from payload, search SDN on this.

Dynamically generating file names for 2 File ( 1: 2 mapping transformation)

Hi ,
I have a scenario Proxy to File(FCC) with 1:2 transformation in message mapping ie 1 sender and 2 receiver interface ....
1 Message mapping
1 Operation mapping
1 RD , 1 ID and 2 file receiver channels and 2 receiver agreements.
I need to dynamically generate the filename say abc.(first 9 characters of mesg id) and xyz.(first 9 characters of mesg id)
I used dynamic configurations with ASMA settings, created 2 UDF assigned each of these to header node of r receiver message types.
Here, I guess the second dynamic configuration is over writing the first dynamic configuration and hence creating only one file with xyz.(first 9 characters of mesg id)
name .
Need your valuable inputs
Thanks and regards,
Pavithra

As dynamic configuration doesnot work in case of 1:n mapping what you need to do is
Create a field Filename in your source data structure
Create a1:1 mapping between your source structure and source structure
In that 1:1 mapping on the target structure assign UDF for file name
Now this target structure will be used as a source structure in your next 1:2 mapping
Under operation mapping add first the 1:1 mapping for source and then the multimapping

Mailing the Report Output-Does not generating file name

Dear Gurus,

Generating File name as versions

Hi,
I have a scenario where in my output file should be generated in versions or sequence.
order_00.xml and nest file as order01.xml so on for every file posted ..
My receiver is a 3rd party system and we are using FTP not NFS..
Any help in achieving this would be appreciated.

Hi,
Instead of going with the sequence number, it would be better to go with the IDOC number.
Here is the code:
public String putDynamicConfiguration(String docnum, Container container) throws StreamTransformationException{
try
     DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
     DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
     String filename = "Prefix_" + docnum + ".txt";
     conf.put(key, filename);
     return docnum;
catch (Exception e)
     return docnum;
you can add a counter function to thiis code to achieve the requirement.
Thanks,

Can I change the File Names the Iphone generates for my photos so I don't have to go and "rename" each photo?

When I take a photo the phone stores it with a self generated file name, however since I have multiple Iphones taking photos, I would like to change the method of this generated filing system.
As an example, photos being taken with Iphone #1 would have Phone1Image1... or some smaller if necessary and then phone 2 would be Phone2Image1...
Then when I go into the cloud I could sort them according to source rather than a random date selection or some other way of filing.
Thanks

Please guide me how to generate in specific folder.
Thanks in advance.

First, LabVIEW 7 allows you to pass string and path data types directly into the Matlab script node. Otherwise, in LV <= 6.1 you can do the following:
In LabVIEW, convert the string to an array of U8s using the String to Byte Array function. Then pass the U8 array into the Matlab script node as a Real Vector type. Finally, in Matlab, convert the Real Vector to a string using the char() function. For example:
stringAsString = char(stringAsRealVector)
Attached is an image that shows how to do this.
Good luck,
-Jim

How to Change the defalut file name of PDF out of report (Version 6i)

Dear All
I have a report which opens from forms(Version 6i); the output of the report is in PDF. The generated file name is the same name as the report. Is there any way to give parameter name of the report as the name of the PDF out put of the report?
For example I have a parameter called PATIENT_ID and my value is 25613 now I need the PDF out put name also 25613.
Thanks and regards

Use DESNAME to specify the output filename:
set_report_object_property(repid, REPORT_DESNAME, :patient_id);

Dynamic File name in FTP Communication Channel

Hi All,
We have requirement where ,we create a filenames dynamically ( runtime).These filenames whihc do change for every execution needs to be added in FTP communication channel.
1. How can we add the this generated file name in FTP CC Communication Channel.
2. Does this file needs to part of target structure during graphical mapping ?
3. Can we also dynamically append the Directory name to file names aswell ?
Please provide your valuable sugestions.
Thanks for your support.

1. How can we add the this generated file name in FTP CC Communication Channel.
3. Can we also dynamically append the Directory name to file names aswell ?
to get the FileName:
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
To get the Directory:
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory");
Then append:
key+key1
And then in the CC select the Directory checkbox under the ASMA properties...
2. Does this file needs to part of target structure during graphical mapping ?
The file which is sent using the CC will have the FileName as configured in the UDF of the graphical mapping....and if i am not wrong then the target structure resembles the file (if there is no FCC done)....
Regards,
Abhishek.

Dynamic file name creation problem

Hi Friends,
I had a requirement where i had to generate file name at target side with the following format
" raw_text_yyyymmddhhmmss.txt" . This can be acheived by using "currentdate" function but there is no field at target side which holds this value, if there was a field then i would have used variable substitution method to generate the file name.Another option is Dynamic Configuration UDF already
my root node is mapped to some src field say FLD1 based on which i will be getting multiple files.
How to customise this udf to get current date as filename for multiple target files:
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
String Outputfile = conf.put(key,a);
return Outputfile;
Regards,
Vinod.

Hi Nityanand,
Your solution is right but actually problem here is recently a slight change was made for file name it should be "raw_text_yyyy-mm-dd-hh-mm-ss.txt" by using variable substitution we get file name as this format "raw_text_yyyymmddhhmmss.txt" .
@Prateek: I cant give Currentdate as direct input to udf becoz we are generating files based on a certain field from source side.We are sorting this multiple source fields and generating target files.
Any suggestions.....
Regards,
Vinod.

HI,
Use substring function in the mapping and give the the values as 5 and 8.
Map to the any field in the Target Structure.
Use the variable substitution in the Receiver File adapter.

BIG PROBLEM: CSS files not loading because of international characters in file name

I have Muse Beta 7 in Spanish.
The program creates a css file called master_a-página-maestra.css in css folder. It is referenced in the resulting HTML code here:

<link rel="stylesheet" type="text/css" href="css/site_global.css?3951792836"/>
<link rel="stylesheet" type="text/css" href="css/master_a-p%c3%a1gina-maestra.css?fileVersionPlaceholder"/>
<link rel="stylesheet" type="text/css" href="css/index.css?3948175564"/>
When you work locally in your Windows formatted har drive, everything looks fine, but when you upload your files to a server, everything is screwed up. The server doesn't recognizes the URL and returns an error page, resulting in style errors in the entire site.
This can also happens with html files if the title of the page contains international characters or with images if the image file name in your Hard Drive contains international characters.
I already pointed out long time ago Muse was generating file names with international characters like á, ñ, etc but nobody cared about it. Too bad. I had to activate file name customization but I think that Muse should replace automatically this characters in the same way that it replaces other conflictive characters like commas or ampersands.
This is not a fault of the FTP client. Accented characters are not web safe regardless of the FTP client you are using. It is a server side issue. Some servers support it some others don't. I don't mind if it works in Adobe Catalyst server because the final website is going to be in another server and maybe next year when paid hosting is ended the client may move it to another server.
It makes more sense to replace accented characters in file names by their not accented equivalents ('a' instead of 'á', 'N' instead of 'Ñ', etc) and avoid all this problem.

Zak, It is funny you mention it, because the site I am talking about is hosted in 1and1. try this: http://www.artofwalls.com/rosannawalls/biografía.html
As you can see, the offending "í" in the file name causes 1and1 server to throw a "page not found" error. And this has happened with many other servers I have tried since.
Muse boast of generating code fully compatible with all major web browsers but by using international characters in file names it ggenerates code suitable only for very few web servers. International characters have been always a no-no for internet URLs. Internet was designed by people who didn't care about ascii codes beyond 127 so using international characters in html file names is just call for problems.
"to work with your hosting provider to determine how to enable Unicode encoded (UTF-8) file names and HTML files on their servers" is not a viable solution most of the time unless you are a Very Important Client of your host provider. If not, making changes means money for them and if you are the only one who complains, they are going to just tell you to not use international characters in your names.
