Load and Write to MimeDocument

Dears,
I would really appreciate if anyone could help me with an example of how to load data into a
MimeDocument object by using the GetLoadStream or Load methods.
In addition, modifying the MIME data by using one of the WriteTo methods.
Since i want to modify the content type header.
Thank you in advance,

You can't use custom objects inside an OSB pipeline. I mean, you can assign it to a variable and send it as an argument to another java callout, but you can't access it's attributes or methods.
Did you try overriding the toString() method of your class? Maybe if you do that the log action will print what you want. If not, then you'd have to use another java callout that returns the String you want to log. You can pass the Customer object as an argument, just use the $cust variable you created before.

How to load and save custom workspaces in PE7

I've written a little utility which allows PE7 users to load and save custom workspaces. It's attached to post #1 of this thread.
System requirements
The utility has been tested with Windows XP Pro SP3 only. It might or might not run under Vista. It will only work with PE7 installations where the executable files are in the default places.
Installation
When you have downloaded the utility (it's only 199KB) you can run it from any convenient place in your system - it doesn't need to be installed as such.
Usage
It's pretty self-explanatory in use but here's the manual!
Run the downloaded utility "PE7WS.exe".
A file selection dialog appears. Choose the workspace layout file you wish to use. "LastUsed.layout" is the last used workspace (that's all you will be offered the first time you run the program). If you press Cancel at this point, the program will exit and nothing will happen.
Once you have selected the workspace, click "Open" and Premiere Elements 7 will run, using the workspace layout you chose.
After you exit from Premiere Elements 7, a workspace layout file save dialog will appear. If you made changes to the workspace during your Premiere Elements 7 session, you can now give the revised workspace a name and save it.
Do not save the workspace in a different directory from that which the dialog offers!
If you have changed an existing custom workspace, and you want to update the version previously stored, just select the name and over-write the saved workspace layout with the new one.
If you don't want to save the workspace at all, just click "Cancel" - next time you run Premiere Elements, you can choose the "LastUsed.layout" workspace to use that last used unsaved workspace in any event.
If you use the PE7WS utility to run Premiere Elements 7, and then you use the menu option "Window > Restore Workspace", then exit, you can either cancel the workspace saving stage, (which will mean that "LastUsed.layout" will contain that default workspace), or you could give that default workspace a name like "PE7 Default" so you can start a future Premiere Elements 7 session with the default workspace, even though you last used a custom workspace.
If you run Premiere Elements 7 in the usual way without using PE7WS.exe, the workspace that appears will be the last used one.
The usual disclaimer...
The utility should be entirely safe in use, but I can't accept responsibility for any loss or damage it might cause. However, the only file manipulation is does is to workspace files in the directory that Premiere Elements 7 uses purely for the purpose - the utility doesn't go anywhere near your precious project files.

I'm finding it very handy on my particular twin 22" monitor setup to sometimes use a one-screen layout and sometimes a two screen layout. I 'discovered' that having the timeline on the second monitor enables me to tweak edits there while having the playback full size after pressing the "full screen" button on the first monitor. Where the timeline would normally be I have the history, mixer, and other windows always open. As the second monitor is also used by another PC (the one I have the net and email etc on) using "Maxivista" monitor sharing software, I revert to single screen layout when doing stuff like exporting to DVD so I can see what is going on with the render while typing stuff like this.
Selectable workspaces are dead handy!

How to load and show PDF on stage in Flash using AlivePDF or PurePDF external libraries?

Hello,
I searched a lot on internet but didn't find a proper way to load and open/show PDF on stage in Flash. Following are my understandings about this topic.
I know Flash does not have the built-in functionality to load and show pdf document on stage.
I know you can do this in AIR application using HTMLLoader class but it required adove reader to be installed on your machine.
I have used AlivePDF/PurePDF and I know how to export/generate a PDF File using these libraries but I don't know how to use them to load and show PDF document on stage in Flash. According to my research, I think these libraries can accomplish my task but how, I don't know. That's because I am here for your help.
People suggest to first convert pdf into an image or swf file and then import it into Flash but I don't want this solution because my clients will be importing/uplading PDF file into my software.
Some people suggest to "Convert PDF renderer code written in C/C++ using Alchemy to flash library" and then use that library to my project. I don't have any idea how to do this. If anyone can help me to achieve required functionality this way, please guide me.
Now you know about my understandings, so you can guide me in better way. Let me give you an example what kind of functionality I want. Please visit: https://www.pdffiller.com. Upload a pdf file there and you will see that it shows that pdf to user (At the moment, I want this functionality) and pdf annotation i.e. write text on pdf and other functionalities.
NOTE: I am not a Flex and AIR developer. I am a Flash (Actionscript 3.0) Developer. So please first help according to flash. If you want to offer the solution according to Flex and AIR, you are most welcome.
I specially want "ADOBE EXPERTS - Adobe Flash developer from Adobe" to comment on this and help me out. It's about 4th day I am without a solution. I am afraid, I'll loose my client if I'll not have a solution in next couple of days.
Thanks,

Just to throw in a $0.02, I looked at those libraries myself quite a while ago and all they had the ability to do was give you information and assets from the PDF. At that point you literally had to read each page in the PDF (whatever the library could extract), use the information it extracted (position, type size, images, etc) and create a layout engine that could "reconstruct" the page piece by piece.
I hope it's better these days but that's what I took from those libraries quite a while ago and it may still be true. That would explain "Convert PDF renderer code written in c/c++ using Alchemy to flash library". Someone may already have written a quality layout engine. Otherwise there was no "load pdf, run this ShowPDF() function to add to display list" functionality at all.

How can I load and save text using FileReference class

Let me start by saying I have no intention of using php and I can't wait until flash cs5 comes out with its new read/write capabilities
I want to load and save XML files (stored on my local hard-drive) in AS3.
I am using the FileReference class.
Firstly I have noticed that when using FileReference.save if you replace an existing file instead of writing over the file data is appended to the end of the file. Can I make it so the file is overwritten (as it should be) or make it impossible for the user to save in such a situation.
Secondly I want to load in text from an external file using FileReference.load I know that somehow you use FileReference.browse first to get it to work but I want to know exactly how to do it.
I have looked for a tutorial about loading text in this manner and have not found one.
Any help would be much appreciated especially if you could point me in the direction of a relevant tutorial
Thanks

the filereference class is for downloading and uploading files.
if you want to load xml, use the xml class.
and, if you want to write to an xml file and don't want to use server-side code, wait.

Read Key and Write Key not working as expected with paths on RT

The configuration file VIs Read Key (Path) and Write Key (Path) don't seem to work as expected (at least not as I was expecting them to) on an RT target.
When working on my WinXP PC with these two VIs, paths are translated to what looks like is supposed to be a device-independent format before being written to disk. The path C:\dir\file.txt becomes /C/dir/file.txt when writing and vice versa when reading. On my RT target, however, that same path is written to disk as C:\dir\file.txt, unchanged from the native format.
The translaton of a native path to and from the device-independent format appears to be the responsibility of Specific Path to Common Path and Common Path to Specific Path. These both use the App.TargetOS property to determine the operating system. In the case structure for these two VIs, however, there is no case for PharLap or RTX. (My RT hardware is runnng PharLap; I don't know enough about RTX to comment.) This means that the results of String to Path or Path to String are used without translating between the device-independent format to the native path format.
This isn't a problem if you create a configuration file on one machine and use it on that same machine. I noticed this only when tranferring a config file from my PC to the RT target, where the target would not open the file paths it loaded from the configuration file.
This occurs on 7.1.1 and 8.0. I don't have 8.20 to see if happens there, too.

In LV 8.2, this was fixed.
The problem is App.TargetOS returns "Pharlap" on RT systems, and "Pharlap" is handled by the default case ("invalid OS target") in LV 8.0. In LV 8.2 the default case is "Windows 95/NT", however. The reason you could write and read an .ini file on RT in LV 8.0 and earlier is because these two VIs (listed below) were both running the default case of "invalid OS target".
vi.lib\Utility\config.llb\Common Path to Specific Path.vi
vi.lib\Utility\config.llb\Specific Path to Common Path.vi
As you saw, this fails when you perform one operation in Pharlap but the other in Windows. You can fix this by modifying the two VIs listed above. Just go to the case structure and make "Windows 95/NT" the default case.

Sql loader and Runtime Excec

Hi!
I am writing a Java application running on windows. the primary thing that the program does is to parse data and write it in a text file , connect to the database and insert the text file to the table by means of an sql loader...
the database that i am connecting on is running on a solaris =)
anybody know how to do this by using the Runtime.exec()? many thanks!! any help is greatly appreciated!! =)
Sample Values:
CASA.CTL -> my sql loader
oracle.jdbc.driver.OracleDriver -> my driver
jdbc:oracle:thin:@172.16.15.240:1521:ABCDE my url
bdoabcd -> my username
password -> my password

Hi Carol!
thanks for the help!...
uhmmm... what is the usual command for running the sql loader?.
Process p = Runtime.getRuntime().exec("Command for sql loader");
Can you give me an example? =) many thanks!

Sql loader and bulk data

hi,
I want to insert 100,000 records daily in a table for the first month and then in next month these records are going to be replaced by new updated records.
there might be few addition and deletion in the previous records also.
actually its consumer data so there might be few consumer who have withdrawn the utility and there will be some more consumer added in the database.
but almost 99% of the previous month data have to be updated/replaced with the fresh month data.
For instance, what i have in my mind is that i will use sql loader to load data for the first month and then i will delete the previous data using sqlPlus and load the fresh month data using sql loader again.
1. Is this ok ? or there is some better solution to this.
2. I have heard of external files, are they feasible in my scenario?
3. I have planned that i will make scripts for sqlPlus and Loader and use them in batch files. (OS windows 2003 server, Oracle 9i database). is there some better choice to make all the procedure automatic?
looking for your suggestions
nadeem ameer

I would suggest u use External tables since its more flexible then
sqlloader & is a better option.
For using external tables
1)u will have to create a directory first
2)Generally creation od directory is done by sys,hence after creating the directory
privileges read & write to be provided to user .
3)Creation of external tables.
4) Now use the table as a normal table to insert ,update delete in
ur table.
U can get more information from
http://www.oracle-base.com/articles/9i/SQLNewFeatures9i.php#ExternalTables
Create Directory <directory_name> as <Directory path where file be present>
Grant read,write on directory <directory_name> to <username>
CREATE TABLE <table_name>
(<column names>)
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY ,directory_name>
ACCESS PARAMETERS
RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ','
LOCATION (<filename>)
PARALLEL 5
REJECT LIMIT 200;
Hope this helps.

How to read and write data from Excel to TestStand without using LabVIEW VIs

Hi,
How can I read in columns of data from Excel into a TestStand array and write columns of data to Excel from TestStand without using LabVIEW VIs?
I don't think the Property Loader custom step type in TestStand will work because the data I would like to read in from Excel is in a column that is thousands of rows long and the data has to be in the proper format to use the Property Loader to load in an array from Excel.
Thanks for your help.

That example does not use LabVIEW and it does about 40% of what you need to do by calling Excel through ActiveX. If you don't know how to use Excel through ActiveX then you'll need to brush up on that.

Using cfhttp to read a page and write its contents to a file.

Hi,
I am trying to get a feed of my ebay store listings to load
into froogle. Unfortunately, ebay provides the feed as a website
not a file and froogle (via GoogleBase) needs the file to be
submitted as an XML file.
Is there a way to use something like cfhttp to load up the
page where the feed is located, scan the page and write it's
contents into an XML file that I can then load up to GoogleBase???
thanks for the help.

ignore me now.... I answered my own question a short while
ago.
for anyone who cares....
I used CFHTTP to get the page and then used a cffile to write
the #cfhttp.filecontent# into the new file!

Late 2009 Mac Mini odd Super Drive Loading and Ejecting Noise

I have had no problems with my Mac Mini until now. Just today I inserted a disk into the super drive and it made a different noise to usual as it took the disk. Also, when I ejected it, it made different noise to what it usually makes. The drive still reads and writes fine it is just the loading and ejecting noise I am worried about.
Help would me much appreciated
cp1996

Sounds like you should be expecting the drive to fail more or less any time now. If the thing is still under warranty, take it in and try to get it replaced. There is a category for abnormal noise when selecting the failure type, so you should have a decent chance. But only if it's under warranty.

after this load ....i used UTL_FILE to unload data and write procedure like ...
CREATE OR REPLACE PROCEDURE R_UTL AS
l_file UTL_FILE.FILE_TYPE;
l_buffer RAW(32767);
l_amount BINARY_INTEGER ;
l_pos INTEGER := 1;
l_blob BLOB;
l_blob_len INTEGER;
BEGIN
SELECT data
INTO l_blob
FROM r_sqlldr
where id= 1;
l_blob_len := DBMS_LOB.GETLENGTH(l_blob);
DBMS_OUTPUT.PUT_LINE('blob length : ' || l_blob_len);
IF (l_blob_len < 32767) THEN
l_amount :=l_blob_len;
ELSE
l_amount := 32767;
END IF;
DBMS_LOB.OPEN(l_blob, DBMS_LOB.LOB_READONLY);
l_file := UTL_FILE.FOPEN('DBDIR1','Kalam_out.pdf','w', 32767);
DBMS_OUTPUT.PUT_LINE('File opened');
WHILE l_pos < l_blob_len LOOP
DBMS_LOB.READ (l_blob, l_amount, l_pos, l_buffer);
DBMS_OUTPUT.PUT_LINE('Blob read');
l_pos := l_pos + l_amount;
UTL_FILE.PUT_RAW(l_file, l_buffer, TRUE);
DBMS_OUTPUT.PUT_LINE('writing to file');
UTL_FILE.FFLUSH(l_file);
UTL_FILE.NEW_LINE(l_file);
END LOOP;
UTL_FILE.FFLUSH(l_file);
UTL_FILE.FCLOSE(l_file);
DBMS_OUTPUT.PUT_LINE('File closed');
DBMS_LOB.CLOSE(l_blob);
EXCEPTION
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(l_file) THEN
UTL_FILE.FCLOSE(l_file);
END IF;
DBMS_OUTPUT.PUT_LINE('Its working at last');
END R_UTL;
This loads data from r_sqlldr table (BOLBS) to files on operating system ,,,
-> Same procedure with minor changes is used to unload other similar files like Images and text files.
In above example : Loading : 3 files 1) Kalam.pdf 2) CTSlogo1.bmp 3) any1.txt are loaded into oracle table r_sqlldr 's 3 rows respectively.
file names into fname column and corresponding data into data ( BLOB) column.
Unload : And than these files are loaded back into their previous format to operating system using UTL_FILE feature of oracle.
so PROBLEM IS : Actual capacity (size ) of these files is getting unloaded back but with quality decreased. And PDF file doesnt even view its data. means size is almot equal to source file but data are lost when i open it.....
and for images .... imgaes are getting loaded an unloaded but with colors changed ....
Also features ( like FFLUSH ) of Oracle 've been used but it never worked
ANY SUGGESTIONS OR aLTERNATE SOLUTION TO LOAD AND UNLOAD PDFs through Oracle ARE REQUESTED.
------------------------------------------------------------------------------------------------------------------------

Thanks Justin ...for a quick response ...
well ... i am loading data into BLOB only and using SQL*Loader ...
I've never used dbms_lob.loadFromFile to do the loads ...
i 've opend a file on network and than used dbms_lob.read and
UTL_FILE.PUT_RAW to read and write data into target file.
actually ...my process is working fine with text files but not with PDF and IMAGES ...
and your doubt of ..."Is the data the proper length after reading it in?" ..m not getting wat r you asking ...but ... i think regarding data length ..there is no problem... except ... source PDF length is 90.4 kb ..and Target is 90.8 kb..
thats it...
So Request u to add some more help ......or should i provide some more details ??

Strain measurment and write to file with NI9237

Hopefully this lab view VI can help some of the novices like myself to acquire strain using the NI9237 and write to a file. The example VI available from NI "Cont Acq Strain Samples (with calibration)" is fine for sampling data and viewing on a chart, but you need to add your own elements if you want to logg data or write to a file.
Since aquistion is continuous, reading and writing data must be done at discrete intervals rather than continuously, or, you will end up with a very large file that can not be easily handles in excel. Also, data gets acquired in "packets" of several samples for each channel, so even if you put a write function within a case structre, as I have done ,and you don't convert the data you get that whole "packet" every time the comand writes to file. Again, you will end up with a lot more data points than you would like.
Though the top level VI is pretty simple, it took me some time and help from many folks for me to figure out what was going on. I thought I would share.
Thanks to Sandra T, Jarrod B, Kyle B, Marc A, Herbert E and Jesse O. for your help
Next goal is to acquire voltage from a different Daq card, convert to load and graph and write load vs. displacement.
hopefully the attached files are the correct method so the VI fuctions with its sub-VI's. If not let me know.

Alfonso

Alfonso,
I'm glad you got your application running. It is also nice that you are wanting to share your code. NI is currently testing a new system that allows community members to share code. If you like, you can also submit your code here.

Read and write existing xml file trouble !

Hi everyone !
i'm trying to save hight score of user in my game by using a xml file , in my xml file has element <best_score>0<best_score/>
and my code to do it is :
XElement best=XElement.Load("Assets/best.xml");
IEnumerable<XElement> loc = best.Elements("best_score");
foreach (XElement elem in loc)
int check=Convert.ToInt32(elem.Value.ToString());
int score_user = Convert.ToInt32(scores.ToString());
if (score_user >= check)
hight_score.Text = score.ToString();
elem.Value = scores.ToString();
// what code to save this xml file after modify ?????
else
list_box.Text = check.ToString();
i down know what method can help me save my xml file after update hight score of user in this case .
Anyone has an idea to solve it for me ? please , thanks you !
sorry about my english !

Hi,
It is not recommended to update a file withing the project, so you need to store it in the IsolatedStorage.
Here is a sample to read and write file in IsolatedStorage,
XDocument xDoc;
var file = Util.ReadFile("XMLFile.xml");
if (file != null)
xDoc = XDocument.Parse(file);
var bestScore = xDoc.Element("best_score").Value;
//do calculation
xDoc.Element("best_score").Value = "200";
Util.SaveFile("XMLFile.xml", xDoc.ToString());
For the above code to work, you need to have a file named "XMLFile.xml" in your IsolatedStorage, with data as "<best_scrore>200</best_scrore>"
To read and write file:
public static class Util
public static void SaveFile(string filename, string data)
try
using (var store = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication())
using (var stream = new IsolatedStorageFileStream(filename, FileMode.Create, FileAccess.ReadWrite, store))
StreamWriter writer = new StreamWriter(stream);
writer.Write(data);
writer.Close();
catch (Exception)
Debug.WriteLine("Couldn't save the file.");
public static string ReadFile(string filename)
try
String data;
if (!IsolatedStorageFile.GetUserStoreForApplication().FileExists(filename)) return null;
using (var store = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication())
using (var stream = new IsolatedStorageFileStream(filename, FileMode.Open, FileAccess.ReadWrite, store))
StreamReader stmReader = new StreamReader(stream);
data = stmReader.ReadToEnd();
stmReader.Close();
return data;
catch (Exception)
return null;
