How to write Date/Time property of tdms file

On the root page of the tdms file, there is a built-in property called "Date/Time" in the first row.
I would like to use it to save the time stamp when the tdms file is created. But in the help file,
I only find the following property constant. So, how can I write to the "Date/Time" property field?
Property
Constant
Data Type
Name
TDMS_FILE_NAME
String (char *)
Description
TDMS_FILE_DESCRIPTION
String (char *)
Title
TDMS_FILE_TITLE
String (char *)
Author
TDMS_FILE_AUTHOR
String (char *)
Thanks for any idea or suggestion.
Solved!
Go to Solution.

Not sure if this is exactly what you want, but have you tried this?
CVIAbsoluteTime CVItime, *t = NULL;
TDMSFileHandle deH = 0;
// Create TDMS file and set some properties
errChk (TDMS_CreateFileEx (file, TDMS_Streaming2_0, TDMS_ByteOrderNative, 0,"example.tdm", "someText", "title", "author", &deH));
GetCurrentCVIAbsoluteTime (&CVItime);
errChk (TDMS_SetFileProperty (deH, "Date/Time", TDMS_Timestamp, CVItime));
// Save and close file
errChk (TDMS_SaveFile (deH));
TDMS_CloseFile (deH);

How to Append date time to the Source File Name in send Port without Orchestration

Hi,
I am using the Macro %SourceFileName%_%datetime%.zip in the filename(Send Port).
say my file name is ABC.zip
But I am getting the output as ABC.zip_2013T083444
Please suggest, How to avoid the extension?
Vignesh S ----------------------------------------------------------- Please use Mark as Answer if my post has solved your problem and use Vote As Helpful if my post was useful.

The problem here is %SourceFileName% context property would return filename “With” extension. So when you use %SourceFileName%_%datetime%.zip you get FileNameWithExtension_Datetime
For this you have to handle it either in customer pipeline component or in orceshtration where you have to remove the extension from the Filename.
Read this post on remove the extension from this file name
msgOut(FILE.ReceivedFileName) = System.IO.Path.GetFileNameWithoutExtension(msgIn(FILE.ReceivedFileName));
After this if you use the
%SourceFileName%_%datetime%.zip macro, you would get the desired output.
If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful.

How to write data from query into Real time cube?

Hi All,
Can anyone explain me step by step how to write data into a real time cube from front end queries.
Thanks in advance

Hi
You can do this using Integrated Planning
You need to create a aggregation level on the Real Time infocube and can create Planning function/sequence, Variables if needed.
Then you can create query on this aggregation level and you can make the keyfigures Input ready in property pane and you can change the data and save it into cube.
Please find below help link which clearly explains step by step about Integrated Planning like creating input ready queries etc.,

How to print date & time stamp on photos?

How to print date & time stamp on photos?

Three methods:
File>process multiple files>labels. Be sure to uncheck "same as source", or the originals will be overwritten. It is best to work on duplicate files, esp. while learning.
Use the horizontal or vertical type tool to add the information manually to each picture file
If the same information is to be applied to several pictures, e.g. a copyright notice, use of a brush made in PSE is very efficient

How to write data to an XML file present under application server

frnds: can ne one tell me, how to write data in to a file, which is present under a application server
Ex: i want to write a string data in to a file test.txt which is present under "http://localhost:8080/<some_webapp>/test.txt"
Note:i have deploted a service<some_webapp> under Tomcat/webapps dir

Very simple. A servlet can writes to that file if it has the good rights.
In the servlet get (or post) method, use a code like this:
import java.io.*;
protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
try {
String filePath = this.getServletContext().getRealPath("/text.txt");//See http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
         PrintWriter writer = new PrintWriter (filePath);
        //or BufferedWriter out = new BufferedWriter(new FileWriter(filePath));
        writer .println("aString");
       writer.flush();
        writer .close();
    } catch (Exception e) {
       e.printStackTrace();
}Hope That Helps

How to write data on to a location other than desktop or application server

Hi all,
I already posted this question.But i didn't get exact answer
Can anyone explain that how to write data on to a share drive located on other Nonsap server.Please I dont want to FTP the file.I dont want that solution.I need to write directly on to that Nonsap share drive..
Thanks,

I guess the only way is sending the file using a XI connection to the non sap system server,generate RFC adapters, inbound, outbound interfaces, using xml or soap or IDOC to move the file to that system.

How to write date format in bdc

how to write date format in bdc report

Hi,
First you have a data decleration i.e data l_format(10) type c.
now if a variable say l_date which is of sy-datum type, you will have to <b>write l_date to l_format</b>, this will transfer the date in which you(user) have set the date format in user settings. Never hard code the format such as dd.mm.yyyy. or mm/dd/yyyy because the may have different formats, and the BDC will fails. After you have used write to to new l_format, pass this new value to BDC recording.
Reward if useful.

How to import data from excel or csv files to Oracle table

hello everybody,
I am new here and new in Oracle. I would like to know the steps how to import data from excel or csv files to Oracle table.
Let say I already have table inside the Oracle. Then my user give me the sets of data inside the Excel Worksheet.
So, how can I import the excel data into Oracle table.
Thank you in advance.
cheers,
shima

Even easier. Download JDeveloper 11G from this site.
Set up the database connection, right click on the table, select Import->Excel and specify your file to load it. On the import pop-up, you must view and update each tab indicating Columns, Data Types, and DML.
Columns -- move the selected columns that you want to load to the box on the right
Data Types -- select column name from second column to which the data for each column of the import file should load
DML -- click this tab to generate the INSERT SQL
Once done click 'Insert'
