Append text through File Connection JSR-075

Hi all and thank you in advance.
Can I append text to a text file which resides in an expansion card? I need the data inside the file to be preserved until I delete the file and the text I enter each time to be writen at the end of the file and stay there.
Any help would be appreciated.

Question about JSR 75, File Connection API

Hi,
I am developing a MIDlet that requires JSR 75 - File Connection API, as it needs to save a text file (.txt) on the Phone Memory or Memory Card if available.
Does Sony Ericsson and Motorola phones allow untrusted (i.e. unsigned) MIDlet to access JSR 75 API? In other words, does it allows WRITE access to write a file? (Nokia phones allow this, with user permission)
Can someone who has JSR75 experience on Motorola or Sony Ericsson phones shed some light?
Thanks!

Hello,
Using the "code" format tags will make your post much more readable. That said, there are some other problems in the aforementioned code. For example -1 signifies the end of a stream and 0 could simply mean no bytes were read.
You should also check exists() and canWrite(). It is possible to be able to read a file and not be able write to it or create a file in the same directory.

My cousin isn't recieving my text messages. We never text through imessage because she is never connected to WIFI. Now, when I text her, it is sending through imessage but she isn't recieving them.

My cousin recently got an Ipad. Ever since then, when we text through our iphones, our thread is through imessage, and when I send her a text, it says delivered, but she isn't recieving them. She insists she has imessage turned off on both devices. She doesn't use imessage because she is never connected to wifi and doesn't want to use her data, so that is why we text through regular texting (green and white). I don't know if this has anything to do with her setting up her ipad, but my texts to her started sending through imessage only right after she set up the new device. My texts are being delivered somewhere because after I text her, it says "delivered" I can also recieve texts from her, she just can't see mine. Again, she said imessage is not activated on either of her devices, so I have no idea what the problem is. She is able to text other people with iphones just fine. We both have an iphone 5S, and she just got a used ipad mini. PLEASE HELP!!

It is no wonder she is not receiving your messages if she has iMessage turned off in her iPad.
For her to receive iMessages on the iPad, she needs to turn iMessage ON in her iPad and then she needs to be connected to the internet in order to receive them. This connection can go through WiFi or through cellular data if her iPad has this functionality, but those two requirements are a must.
1. iMessages ON
2. iPad connected to Wifi or cellular data.

How to append records in a file, through file adapter.

Hi All,
How to append records in a file, through file adapter.
I have to read data from database and need to append all records in a file.
Thanks in Advance.

Hi,
I think you have a while loop to hit the DB in your Process (As you said you have to fetch data from DB 10 times if 1000 rec are there)
First sopy your DB O/P to one var
and from second time append to previous data.(Otherwise you can directly use append from starting instead of copy and append)
When loop completes you can transform to File adapter Var.
Otherwise you can configure yourFileadapter such that it will aapend current records to previous records.
You can use 'Append= true' in your file adapter wsdl.
It will append previous records to current records in the same file.

Write to text file. Append to existing file. Create file if file doesn't exist.

Hi folks,
up to LabVIEW 7 there was a wonderful "Write to Text File" vi which allowed the option "Append to File". Now, in LabVIEW 8, this old vi is not longer supported anymore. Instead, I am suggested to use a new "Write to Text File" vi. This vi does not offer the option "Append to File" anymore. Rather it is proposed in the online help that one should use the "Set File Position" in order to append text to the file. This much less straightforward than the old solution. Furthermore, I miss an option which would create the complete path if it doesn't exist yet.
To summarize: Isn't there really any smart "Write to Text File" vi available which offers both the options "Append" and "Create path if file does not yet exist". Of course, I could write such a file on my own but I am sure that it is of such general interest that it already exist. In any situation, when a log file shall be written, the wanted vi would be ideal.
Thanks a lot,
Peter

Ray,
I know that the old vi is still available. See the screenshot which I attach to this message. What I am missing is an option "Create file or even complete path if file or path do not yet exist.". Is there any reason why NI doesn't provide neither this option nor a simple "Append to file" functionality in the new "Write to Text File" vi?
Regards,
Peter

Appended text file in loop adds unwanted delimiter value at end of each iteration.

I am using 'Export To Spreadsheet.vi' in a loop which saves a text file and appends data from a 1D array waveform for each iteration. My problem is that at the end of every iteration an extra delimiter value is appended to the file. When I then attempt to graph my data, I get gaps, as seen below (circled in black).
When I start to analyze the data, I'm sure this will be a nuisance. I can not seem to find a solution to this problem. Any advise would be greatly appreciated.
Thanks.
Solved!
Go to Solution.

Export Waveforms... does indeed place an end of line at the end of the last line, resulting in a gap when the next batch of data is appended. I just had the same problem with a VI that a co-worker had written.
The fix is non-trivial. First, make a copy of the Vi to a new location and with a modified name. (If you change a VI in vi.lib, it causes all kinds of problems.)
Then go in and place string indicators various places until you find where the extra EOL characters are. The output of Array to Spreadsheet String ends with EOL. I do not have all the other changes readily accessible. I think we also changed the time format because the default setting lost resolution.
That VI opens, writes, and closes the file on every call so this is not very efficient for frequent calls.
It would almost be easier to write a Waveform to String formatting VI which does what you want and then use the standard OpenCreate/Replace File, Write to Text File, and Close File functions.

Append text in a file?

How can i append text in a text file?
Thanks in advance.

FileOutputStream has two constructors which allow appends: FileOutputStream(File file, boolean append)
FileOutputStream(String name, boolean append)

I can only text through ordinary message when not connected to the internet to someone, but when I am connected, it is automatically assumed as iMessage. How will I text ordinarily without turning off the net? Thank you!

I am from the Philippines btw. What I meant is, I cannot text someone ordinarily when the net is turned on, and it assumes to be texting through iMessage. How will I text someone without turning off the internet in an ordinary way, not in iMessage? Thank you.

I Tried that already, but if i turned it off, I cannot send an imessage to people I want to text through imessage. There are people in my contacts that when I text, it is automatically as text message, while there are some that when I text, it is through iMessage automatically, and I just want through text message also. And for the latter, I still need to turn off the wifi in my phone for them to be texted through iMessage, which is more hassle.

Problem with scrolling text through arrow keys after exporting file to html

I am using Fash Professional CS6. I have created a text box that I can scroll through the scroll wheel of my mouse, as the scroll bar is hidden. But when I try to scroll the text through the arrow keys it is not allowing me to so that. As this is website and everyone is not going to have a scroll wheel, I have to make the arrow keys work to scroll the text. Could you please help me in fixing this problem? I tried to search this problem, but I haven't seen any questions so far.

if tf is your textfield:
stage.addEventListener(KeyboardEvent.KEY_DOWN,f);
function f(e:KeyboardEvent):void{
    if(e.keyCode==38){
        tf.scrollV++;
    } else if(e.keyCode==40){
        tf.scrollV--;

Problem with Append mode in File Receiver

Hello,
I am facing some problem with Append Mode in File Receiver.
In channel config, i have given :
Construction Mode : Append
File Type : Text
Message Protocol : File Content Conversion
The size of the file which i am trying to send is about 9.5MB.
I got this error,
"Recovering from loss of connection to database; message
loaded into queue by recover job: System Job (Failover Recovery)".
So, it would seem that there was a loss of connnection to the database
while the file was being written.
Note - XI successfully recovered from the connection loss and
successfully wrote the file, however since the communication channel
was set to append, it appended to the partial file that was written
before the database connection loss. This is not correct. The file
should have been overwritten after the recovery even though the communication
channel was configured to append.
Can anyone help me on this regard.
Thanks,
Soorya.

Hi Venkat,
I would suggest u to split the file in to chunks if u face any problem in processing at a time in append mode and also
Memory Requirements are must 4 processing huge files:
Q: Which memory requirements does the File Adapter have? Is there a restriction on the maximum file size it can process?
A: The maximum file size that can be processed by the File Adapter depends on a number of factors:
o The most important one is the size of the Java heap, which is shared among all messages processed at a certain point in time. In order to be able to process larger messages without an out of memory error (OOM), it is recommended to increase the size of the available Java heap and/or to reduce the concurrency in the system so that fewer messages are processed in parallel.
o Another factor negatively influencing the maximum message size in releases up to and including XI 3.0 SP 13 is an enabled charcter set (encoding) conversion if the message type is set to "Text".
o Using the transport protocol "File Transfer Protocol (FTP)" also uses more memory for processing than the transport protocol "File System (NFS)" (up to and including XI 3.0 SP 13).
o If the Message Protocol "File Content Conversion" is used in a File Sender channel, consider that not only the size of the input file affects the File Adapter's memory usage, but even more the size of the XML resulting from the conversion, which is usually a few factors larger than the original plain text file.
To reduce the memory consumption in this scenario, consider configuring the setting "Maximum Recordsets per Message" for the sender channel. This will cause the input file to be split into multiple smaller mesages.
Plz do refer the following links:
U may plan the availability of ur communication channel using "Planning Availability Times" feature

FTP to Read content of Text/xml file

Hi,
I need a help for reading content of text/xml file through FTP. Below I just am explaining the scenario.
Our application server is in UNIX. Now we have to run a report program to access in to a FTP server which is in windows platform. Using FTP_CONNECT, FTP_COMMAND, FTP_DISCONNECT we are able to connect to FTP server and also able to copy files from FTP server to SAP application server. After copied in application server, we are able to read the content of the txt file in to internal table in ABAP program using OPEN DATASET. But our requirement is that we want to read the text or xml file content into internal table while accessing into FTP server from SAP application instead of after copying the file into application server.
So please help me to solve my problem.
-Pk

Thank you Bala,
But can you help me what should I pass against FNAME and CHARACTER_MODE Import parameter? Should I pass the full path of the file with name or only I have to pass file name ? For example if my text file name in FTP Server is test.txt and the IP of the ftp server is 10.10.2.3 then should I pass the value against FNAME as '
10.10.2.3\xyz\text.txt' ? Here xyz is the name of the directory in C drive where test.txt is exist.
Please help me.

Reading controller data into LabVIEW through serial connections to controllers?

I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar?
I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days.
My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll. Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program.
I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)?
Any info would be great.
Regards,
Dave

Thanks Dennis.
I spoke with Envirotronics and they do not provide the driver for the System Plus controller any longer since there were issues with changing hardware and software. Their IT department may be able to put something together for me.
Using USB->RS232 connections would be nice given the abundant number of USB ports available on modern PCs.
Without a driver I see parsing the serial text as a challenge in LabVIEW. I know how to approach this with a traditional programming language but are there any examples around here of how this is done with LV (most recent version is fine)?

Open HUB ( SAP BW ) to SAP HANA through DB Connection data loading , Delete data from table option is not working Please help any one from this forum

Issue:
I have SAP BW system and SAP HANA System
SAP BW to SAP HANA connecting through a DB Connection (named HANA)
Whenever I created any Open Hub as Destination like DB Table with the help of DB Connection, table will be created at HANA Schema level ( L_F50800_D )
Executed the Open Hub service without checking DELETING Data from table option
Data loaded with 16 Records from BW to HANA same
Second time again executed from BW to HANA now 32 records came ( it is going to append )
Executed the Open Hub service with checking DELETING Data from table option
Now am getting short Dump DBIF_RSQL_TABLE_KNOWN getting
If checking in SAP BW system tio SAP BW system it is working fine ..
will this option supports through DB Connection or not ?
Please follow the attachemnet along with this discussion and help me to resolve how ?
From
Santhosh Kumar

Hi Ramanjaneyulu ,
First of all thanks for the reply ,
Here the issue is At OH level ( Definition Level - DESTINATION TAB and FIELD DEFINITION )
in that there is check box i have selected already that is what my issue even though selected also
not performing the deletion from target level .
SAP BW - to SAP HANA via DBC connection
1. first time from BW suppose 16 records - Dtp Executed -loaded up to HANA - 16 same
2. second time again executed from BW - now hana side appaended means 16+16 = 32
3. so that i used to select the check box at OH level like Deleting data from table
4. Now excuted the DTP it throws an Short Dump - DBIF_RSQL_TABLE_KNOWN
Now please tell me how to resolve this ? will this option is applicable for HANA mean to say like , deleting data from table option ...
Thanks
