Email a created text file by the click of a button
Hi
What I am trying to do it that: In the Front Panels, All the data is collected via String Control and other Control, then when a press saved, a text file is created and stored in the path that I specified.
It is possible in LabView to using a Button called 'Email Created File' to then e-mail that file as an attachment.
What VIs or example does such a thing?
P.S. I'm deploying it to a PDA.
Cheers

Create text file in Database Trigger
Hello,
How to create text file in the database trigger. I am working on Row level trigger which has select statement if statement fails I have to create text file and insert record in text file. I tried to use file1 TEXT_IO.FILE_TYPE package it does not works.
Thanks,
AtifTEXT_IO is not available on the database. It is only available if you are doing client-side PL/SQL development in Oracle Forms. On the database side, you can use the UTL_FILE package.
Since writing to a file is not transactional, however, and because Oracle may have to call a trigger multiple times to ensure write consistency:

http://tkyte.blogspot.com/2005/08/something-different-part-i-of-iii.html
you aregenerally better off not writing to a file in a trigger. The better answer is generally to use Oracle Asynchronous Queues to send a message to another process that actually writes the file. That way, if the transaction rolls back, nothing gets written to the file.

Text created in Premiere showing other text files in the timeline and exports.
Hi,
I'm creating slates with text generated in Premiere. For each new slate I am duplicating a text layer, Option + Dragging the duplicate file over the text I'd like to replace, then opening the new text layer in the text editor and updating the information.
Things seem fine at first and then randomly text layers in the timeline will show text from other files in the timeline. If I open the text file up in the text editor I see the correct info but not in the timeline.
The only fix I have found is to delete render files, move the text layer around in the timeline, quit and re-open. But still, sometimes when I export, the export preview window will show the wrong text and when I export the file I create shows the wrong text as well.
It seems like Premiere is getting confused by multiple text files in the timeline and is pointing to the wrong cache files.
Thoughts would be a huge help!Thanks for the tip Kevin. Anything I can do to avoid this in the future?
I've had this happen on a number of projects. My media and project files are on a SAN, cache and previews are local.
Thanks,

HOw to create a text file in the given path and delete it after the use?
Hi all,
I am trying to create a text file at the given path and delete the created file after the use.
I am using following code.:
import java.io.*;
// write binary data as characters
public class RanIO {
public static void main(String f[])
// First illustrate append
String lineSep = "\n";
try {
File temp= new File("C:/Ash","cute.txt");
boolean ch=temp.createNewFile();
if(ch)
System.out.println("file created");
else
System.out.println("file Not created");
//writing to file
/* PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
p.print("Emp NO");
p.close();*/
// Open fileWriter in append mode
FileWriter fos = new FileWriter(temp, true);
BufferedWriter bw = new BufferedWriter(fos);
PrintWriter pw = new PrintWriter(fos);
double d=550;
// lineSep = System.getProperty("line.separator");
pw.print("Hello");
//pw.print( lineSep );
pw.print( d );
pw.close();
boolean det=temp.delete();
if(det)
System.out.println("File deleted");
else
System.out.println("File not deleted");
} catch (IOException ioe)
System.out.println( "Append IO error:" + ioe );
My problem:
1)
I am not able to write to the file. I want to know, where i am going wrong.
It is giving error message like
"Canot resolve Symbol: temp,"
But, FileWriter Constructor should accept a File type parameter.
here temp is a file parameter.
If i am not using file=new file();
i can't delete the file after the use. i.e if i use
PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
how can i delete cute.txt after the use?
2)
I am not able to write to the text file. file is created but, a blank file.
"Hello" is not written into the text file.
can anyone help me in this regard
Thanks in advance
AshviniThank you Ram,
But, i want to create a text file in Append mode.
for that i used
FileWriter fos = new FileWriter(temp,true); But, it is not accepting FileWriter constructor in
this format. if i use
FileWriter fos = new
FileWriter("c:/ash/cute.txt",true); it works fine. !!!!!Here's the javadoc
public FileWriter(File file,
boolean append)
throws IOExceptionConstructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
Parameters:
file - a File object to write to
append - if true, then bytes will be written to the end of the file rather than the beginning
Throws:
IOException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
Since:
1.4
Are you using jdk.13 or lower ?
>
ONe more doubt, Does flush method deletes a file?
if not, then i need to use
File temp=new File("c:/ash/cute.txt");
FileWriter fos = new FileWriter(temp,true); //which
is again a problem
if(temp.delete())
out.println("File is deleted");
}I don't know whether i am taking it wrong ! or
anything wrong with my coding ! but, after creating
and writing data into a text file. I must delete it
as it contains confidential informations.
Regards,
Thanks.'flush' writes to a file immediately. Else you should explicitly call 'flush' to write contents from buffer to underlying source.
javadoc again
PrintWriter
public PrintWriter(Writer out,
boolean autoFlush)Create a new PrintWriter.
Parameters:
out - A character-output stream
autoFlush - A boolean; if true, the println, printf, or format methods will flush the output buffer

Create a new dimension in business layer from Data source: text file on the web
Hi,
I have a text data source which is published every few hours that is accessible from a certain URL. I follow the instruction given in this http://scn.sap.com/docs/DOC-43144 - where it shows in great detail how to create the connection, data foundation as well as business layer to create a universe for this type of data.
All is well - I can use this universe in my WEBI doc and display the data.
However, in order for me to merge the data from this universe with another universe, I need to create new dimension based on the data from the text file. The new dimension value is simply the first 4 characters of the Subject found in the text file. The "Subject" dimension is of variant type: varchar.
Following the guide mentioned earlier, the connection is using SAP BO OpenConnectivity driver. And this driver limits severely the SQL statement that I can use to extract a substring of another string. Here's the screenshot of the SQl expression that I can use with this driver
After hours of searching, I cannot find any other connection driver for a text file that's published on a certain URL. The BO OpenConnection driver is the best that I could find.
So here are my problems
1. one of my data source is a text file published on a web
2. the only connection I can create does not allow me to create new dimension in the universe to create an important column "subject ID"
3. I can create the column in webi as a variable. But when I do so, I cannot merge it with existing dimension (webi not allowing to merge these 2 types). And without the merge, the flat file universe with my database universe can't be combined.
I'm using WEBI Rich client version 4.1 SP3 Patch 1. Build 14.1.3.1300
Is there any other idea that you can suggest without requiring to change the extracted data?
Thanks.
With warm regardsHi Bala,
Were you able to find out a solution for the problem with uploading values for a variable from a text file on the web? I am confronted with the same request from users.
Thanks,

Retrieve data from a text file, incrementing the last value and save new value below
Hi
This was working initially. It is part of my LabView Project. I was trying to create a unique number that increments every time the adds the value to the list. It works on computer perfectly. But when I put this on a PDA, it seems to create a blank space when reading the contents of the text file after the last value, which means 0 + 1, which is not what I want.
Please run the testUniqueNoOnPDA.vi first and change the path to C:\uniqueNumber.txt and save the uniqueNumber.txt file to your C drive and see What I am trying to do. Click the Enter button to increment.
Why does the PDA create a blank space after the last value and a computer does not?
I was working perfectly all week and it is not working well now.
Help please, I think I'm missing something

Create New File with Right-Click
Is there a way to right-click on the Desktop and select an option to create a new text file? (I was asked this by a recent Windows convert and don't know how to do it myself.)
Jay Bullock wrote:
I don't think so. However, if TextEdit is in your Dock, it takes just one click on that application's icon to open a new text file.
You can also keep a blank text file in the dock. A click pops up a blank text file. -
Im starting out with 3 different files of text saved as "tab delimited text" from excel, I open a document in ID with 107 pages and create 3 boxes in the master on top of a pdf. I then override all 107 pages so that the text I insert will flow to the next page and so on, once I paste the 2nd text file into the next text frame it skips the original 107 files and starts flowing into new pages. Im ready to pull my hair out, I have been trying to figure this out for 2 hours. I dont know what to do at this point. I think Im getting a migraine.
I would have done a data merge on 2 of the files but the third HAS to be text flow (which gives me the same problem above) because it has to be physically changed to fit each page.Are you Placing the text from an external file, or pasting it from the clipboard?
If Placing, move the loaded cursor inside one of the master frames on the first page, hold down the Shift key and click, being sure the cursor is not on any sort of guide. The entire text file will flow using the master text frames, and ID will add all the require pages to place all the text.
If pasting, you can either override the frame on the first page only, or make a temporary first frame on the pasteboard. Paste into this frame, which will result in a red plus sign in the bottom right corner of the text frame indicating overset text. Switch to the Selection tool (black arrow) and click on the plus sign to pick up the overset text. Hover the new loaded cursor over the frame on the second page, or over the first page as above if you used a temporary frame, hodl the Shift key and click. Delete the temporary frame, if you used one, and the text will reflow to start in the first real frame, but you may have to pick up overset again in the last frame due to the reflow. -
I would like to plott data from a text file in the same way as a media player does from a video file. I’m not sure how to create the pointer slide function. The vi could look something like the attached jpg.
Please, can some one help me?

Plotting from a text file like a media player example.jpg 61 KBHI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

Problem in creating text file from report file
Hello Everybody...
I have problem in creating text file.
I had set System Parameter as below
DESTYPE : File
MODE : Character
DESNAME : gayu.txt
And ruler setting
Units : Character Cells
Character Cell Size : Horiziontal = 7
Vertiacle =12
GridSpacing : 1
no of snap points per grid spacing : 1
but when i run report it will give error
"REP_1219 M_2 or R_2 has no size -- length or width zero"
so is there any solution of that
or another way to convert report into text file?....Hi Folks,
Please don't go after that Error as its a very deceptive one. Please don't go for altering your design Or changing the size of items in your layout.
Similar errors I have come across in reports. I think its due to file transfer type. You might have transferred the file in Binary and your File Mode I am seeing it as CHAR.
This normally happens while making the Report Format as "Text". Either you change that format which I think is possible in your case as your basic requirement is making a report output of CHAR type.
Please check for this error in Metalink and proceed accordingly. I could fix similar errors when I changed Format type to PDF(from text).

when I send an email with a photoshop file attached, the recipient receives it "flattened". How do I change this?
I've sent psd files to various people without issues, however you might want to try something like www.filedropper.com to make sure it's not that they can't open your version of psd file.
You may also want to zip the file using the built in archiving software, simply right click (or control click) the file and choose Compress ...., then you can email it to the person as a compressed archive. That should preserve all the aspects of the file properly without any modifications. -
