How to read an int value to a file

Hello programmers.

I am facing a problem no doubt very simple but which has kept me stuck for some time, so I'm now looking for your help.

int i = 0;

try {}
FileConnection fconn = (FileConnection) Connector.open (System.getProperty ("fileconn.dir.photos") + "increment.txt", Connector.READ_WRITE);
If (fconn.exists ()) {}
OutputStream os = fconn.openOutputStream ();
String value = "1";
OS. Write (value. GetBytes());
OS. Close();
InputStream is = fconn.openInputStream ();
i = Integer.parseInt (is. ToString());
is. Close();
}
If (! fconn.exists ()) {}
fconn. Create() ;}
fconn. Close();
}
catch (IOException ioe) {}

I know that the file of the photo isn't the best idea, it's just a test. So, when I go into the increment.txt file, I see that a '1' is written, however, when I try to start it I get a NumberFormatException, do you know why and how I can solve this problem?

Thank you very much for any help, I won't forget the congratulations...

Yes indeed you're right, it works!

Thanks a lot again Simon, you be everhelpfull in my daily programming efforts.

Here is the final code that worked for me:

InputStream is = fconn.openInputStream ();
InputStreamReader isr = new InputStreamReader (is, "UTF8");
StringBuffer buffer = new StringBuffer();
int ch;
While ((ch = isr.read ()) >-1) {}
buffer. Append ((Char) ch) ;}

Temp = buffer. ToString();
Temp.Trim ();
i = Integer.parseInt (temp);
is. Close();

Bravo to you, of course...

How to read a counter value for the separation of the two edge before meter is stopped by the second edge (6602 Council)?

I use a timer/counter with DAQmx 6602. I use the separation of two - available via DAQmx cash edge. Count between the two edges works properly, however I do not know how to read the value of the counter during the counting operation (i.e. after the first edge triggered the beginning of the count, but before the second edge triggered the end of the counting). I'll have to wait for the second goes off the edge of the end of the countdown until I can get a counter value. I need to be able to access the current value of the County during the count operation. This was possible in traditional DAQ. How can it be accomplished using DAQmx?

Ah shoot - I was afraid that this might be the case (for what it's worth, my series of X returned intermediate values, but the material and the underlying driver are quite different)...

You just need to take one measure at a time or you are buffer several measures of separation of the two edges at the same time? So just to take one measure at a time, you can set a task of edges of count using the database internal time as the source using an arm start trigger (first edge) and a sample of clock (second Board) to work around the problem.

How to read the content .vmtx of the file using PowerCLI

Hi all

I have a virtual computer model in one of the NFS attached to my ESX host data stores.
I need to get the display name and some other details of the vmtx this model file.
Any method to get values from vmtx file using PowerCLI... ?

Thank you in advace for all help.

Hello, MattGeorgey-

One way you could do this would be to use the Copy-DatastoreItem cmdlet to retrieve the .vmtx file, and then you can read it, Get-Content on it, etc., as you please. Something like:
```
## copy the VMTX file from the datastore to a local spotCopy-DatastoreItem vmstore:\MyDatacenterName\my_datastore_name\myTemplate\myTemplate.vmtx C:\temp\.

## get the contents of the VMTX file$colVMTXContents = gc C:\Temp\myTemplate.vmtx## get the line that contains the "displayName" value$colVMTXContents | Select-String displayName
```
And, you can access some of the elements that are specified in the file .vmtx using the property Config.ExtraConfig of the display of the model as object:
```
## get the template object$tmplMyTemplate = Get-Template myTemplate## get a particular value for an ExtraConfig item$tmplMyTemplate.ExtensionData.Config.ExtraConfig | ?{$_.Key -eq "nvram"}
```
How do I?

You needn't PL/SQL for it. Just use XMLTABLE:

with t as)

Select xmltype (')

84188

125148

251486

125147

125511

double x)

Select PartyID,

RelAcctID

t,.

XMLTable)

' / PrtyActDtlRequest/AcctInfo.

go x

PartyID path number "PartyID,

Path RelAcctIDXml xmltype "RelAcctID."

),

XMLTable)

'RelAcctID '.

by the way RelAcctIDXml

columns

RelAcctID path number ' / RelAcctID'

)

/

Hello CAs,
Welcome to the community of Sony.

What is the model number of the digital book reader?

The reader supports text formats (.txt) as well as the two following formats:
-File EPUB (.epub) EPUB (version 2.0 of PAHO) taken in charge
-PDF file (.pdf) support is based on the PDF 1.6 specification.

The default language on your Reader Digital Book setting does not affect the language in which the book is. Reading in a foreign language, you will have to buy them specifically in this language.

How to read the NAVE of Nikon D600 files

I bought a Nikon D600 but am unable to read NEF files read with my version of Lightroom 3 that works on an older Mac Book which cannot be upgraded to LR4. If I buy a new Mac, can I switch to LR4 on the new machine, or I have to buy a new version? If I can improve how to transfer LR3 for the new machine. Also, I'm a student of Photoshop CS5 Extended version. Can I buy an upgrade to CS6 on a new machine?
In doing research I saw where 4 Lightroom and Photoshop CS6 had some problems with Apple OS X 10.8. Have they been resolved?

The D600 is made sound supported by Lightroom 4.2/camera Rw 7.2 and higher. Then updgrading 4 Lightroom or Photoshop CS6 will provide full support for the D600. Alternatively, you can download the free 7.2 or later version DNG Converter and use to convert your NEF files to DNG format that is already supported by Lightroom 3.x

You can spend to Lr4 Lr3 on your old or new machine has no activation code to stop. You'll probbaly prompted for the serial number for Lr3 on the new machine to prove that an upgrade is legitimate. Buy Photoshop CS6 then upgrading the new machine that is also possible, but you need either the DVD for CS5 or have already installed on the new machine. Basically, the CS6 needs to see a copy of CS5 is available for installation or already on the computer.

Regarding problems with 10.8. They have been addressed.

How to read labels and labels in a file XML in SQL and PL/SQL?
I have a few steps in Oracle to select the contents of an xml file, which works very well if all the labels and tags in the xml file is what I want.
My problem is that sometimes someone will change tags in an xml file and not tell me. If it happened, my select statement
does not return an error. If the XMLTABLE ('/ tblCageDuns/CageDuns ' part does not match the xml file (ex: instead of CageDuns, the xml file can))
have CageDun), I get no return lines. If one of the 'columns' does not match (ex: instead of "cage" the xml file can have "cages"), I get a null value
the value of the column. Is there a way to read what all the labels and the labels are in the xml file, so I can check them before I try to query the data?

Here are my basic steps:

1 create a table with an XML column:

create table cagexml_col)
xmlfile_id number primary key,
xmlfile_doc XMLType);

2. Insert the xml document:

insert into cagexml_col values (1,
XMLType (bfilename ('ING_FEED', 'CAGEDUNS.xml'),
nls_charset_id ('AL32UTF8')));

3. reading data:

Select xmlfile_id,
a.CAGE,
a.DUNS,
a.SRCFLAG
OF cagexml_col.
XMLTABLE ('/ tblCageDuns/CageDuns ')
PASSAGE cagexml_col.xmlfile_doc
COLUMNS
CAGE VARCHAR2 (5) Path "cage."
Path of VARCHAR2 (9) "duns, DUNS
SRCFLAG number Path 'SrcFlag '.
) a
where xmlfile_id = 1;

Here is an example of file CAGEDUNS.xml.

< tblCageDuns > < CageDuns > < cage > AAA87 < / cage > < duns > 111149236 < / duns > < SrcFlag > 0 < / SrcFlag > < / CageDuns > < CageDuns > < cage > BBB95 < / cage > < duns > 222245890 < / duns > < SrcFlag > 4099 < / SrcFlag > < / CageDuns > < CageDuns > < cage > CCC90 < / cage > < duns > 333368885 < / duns > < SrcFlag > 3 < / SrcFlag > < / CageDuns > < CageDuns > < cage > DDD14 < / cage > < duns > 444437379 < / duns > < SrcFlag > 3 < / SrcFlag > < / CageDuns > < CageDuns > < cage > EEE77 < / cage > < duns > 555597063 < / duns > < SrcFlag > 4097 < / SrcFlag > < / CageDuns > < CageDuns > < cage > FFF56 < / cage > < duns > 666639159 < / duns > < SrcFlag > 3 < /.

You can try the following, it will return all of tag names in the order of the document:
```
select x.tagname
from cagexml_col t,
     xmltable('/descendant::*'
       passing t.xmlfile_doc

How to read my waveform data from a file LVM?

I have collected a form of wave and saved using the file LVM format. I would read the waveform in labview and view with its timestamp and assigned name. The only way that I could read the data in Labview was to convert it to an array of number. I thought that if you could write a waveform and save all data, you should be able to read it back quite easily. I have included my LVM file and two simple programs. The program I use is much larger, but these two programs are representative of what I'm trying to accomplish.

Thank you

Eric,

I am pleased that you have something that can work even if it is not ideal.
I close this service request, but I thought that I'll let you know that
because of your issues, I have revised article in the Knowledge Base on
timestamps and verified for accuracy and thought you should know.

What is the precision of the timestamp of the waveform returned by my NOR-DAQmx
Device?

Why are you not using NODE.js as code below:

Could you help me, please?

User, tell us your version of Jdev, please!

You should not read the model layer cookie values. You can read them from the view controller and pass them on to the model layer, the module of your application.

To do this, you define a method in the application module that you call from a bean where read you the cookie.
