I am working in Xamarin Forms with an iOS app.
The code downloaded successfully an sqlite file and I moved the file to the following location:
/var/mobile/Containers/Data/Application/787D3CB8-01E1-41BB-B786-972534E7F563/Documents/Data/test-file.sqlite
but now when I try to open it with the following code I get a strange error:
SQLite.SQLiteException: 'file is not a database'
The database is also not encrypted
here is my code:
var db = new SQLiteAsyncConnection(_dbPath);
var versionlist = await db.QueryAsync<version_history>("SELECT * FROM version_history ORDER BY id DESC LIMIT 1")
after I do the QueryAsync I get the error, the file is not a database.
but the db object does have the information
Please help me, any ideas?
It turned out it wasn't a real sqlite file after all. It was a zip file but named as a sqlite file and the more crazy is, the fact that it was readable by the sql lite lib, when using SQLiteAsyncConnection.
Even when it was a zip file.
But the moment you fire a query, you will get the error saying that it is not a database.
SSIS hangs and I am unable to open the solution. In the lower left corner there is a message "Testing Connectivity". SSIS does not respond to any command, it does not let me access the package or change any setting.
In Windows explorer, Go to the folder with the solution and package that you cannot open
Open the user preferences file , that is the file with the extension .user
Open the file in a text editor and find the setting for OfflineMode
Change the value to true, it should look like this: "OfflineMode > true< / OfflineMode>" (wihtout the spaces)
I need some help with PHPEXCEL library, everything works great, I'm successfully extracting my SQL query to excel5 file, I need to give this file to transport company in order to auto collect informations about packages, unfotunately the generated excel file has some ascii characters between each letter of the cell text, and when the excel file is imported you need to manually delete these charaters.
If I open the excel file, everything is fine I see: COMPANY NAME, If I open the excel file with notepad++, I see the cell values this way: C(NUL)O(NUL)M(NUL)P(NUL)A(NUL)N(NUL)Y N(NUL)A(NUL)M(NUL)E
If I open again the file with excel and save, then reopen with notepad++ I see COMPANY NAME.
So I do not understan why every time I create an excel file using PHPEXCEL my every letter of all words are filled with (nul) every letter.
So how do I prevent the generated excel file to include (nul) between every word????
Also if you open the original excel file generated from PHPExcel samples are also filled with (nul) and if you open and save it, the (nul) is gone.
Any help would be appreciated, thanks.
what is the (nul) ??? 0x00??? char(0)???
ok, here is the example:
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');
if (PHP_SAPI == 'cli')
die('Disponibile solo su browser');
require_once dirname(__FILE__) . '/Classes/PHPExcel.php';
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("Solidus")
->setLastModifiedBy("Solidus")
->setTitle("Import web")
->setSubject("Import File")
->setDescription("n.a")
->setKeywords("n.a")
->setCategory("n.a");
$objPHPExcel->setActiveSheetIndex(0)
->setCellValueExplicit("A1", "COMPANY")
->setCellValue('A2', 'SAMSUNG');
$objPHPExcel->getActiveSheet()->setTitle('DDT');
$objPHPExcel->setActiveSheetIndex(0);
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="TEST.xls"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
header('Cache-Control: private',false);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
ob_end_clean();
$objWriter->save('php://output');
As you can see from this little example, this scripts creates a file excel5 with 2 cells, A1 = COMPANY, A2 = SAMSUNG
when I send this file to the transport company, they import the file into their system, but as you can see from the picture, there is an weird character between each letter.
so I noticed every time I open the generated Excel5 with notepad++ file I get:
S(nul)A(nul)M(nul)S(nul)U(nul)N(nul)G
If I save the save with excel and then open it again with notepad++ I get:
SAMSUNG
and this file is ok for the transport company
so my question is, how should I avoid the file generated to contain thi '(nul) charachter between each letter????
some help?
weird characters
SAMSUNG
I found the soluion by myself, I explain just in case anyone has also this problem:
there is not way to change the way the excelfile is encoded by PHPEXCEL
so I figured out the problem was reading the file, I did some simulations and reproduce the problem, every time a read the file and put the result into inputs a get weird characters:
C�O�M�P�A�N�Y�
If I set the output enconding enconding as follows:
$excel->setOutputEncoding('UTF-8');
the file loads fine, so the problem was not creating the excel file, but reading the excel file.
If I print the variable with ECHO I get: "COMPANY",
if I put the variable on input as value I get: "C�O�M�P�A�N�Y�"
setting the output solves the problem, but I would like to know why the difference when I put the variable on input as value, thanks
I'm just getting started with Neo4j, and have been trying to create my first project in Neo4j Community with a small sample data from a CSV. I keep getting an invalid input/syntax error (see image below).
The problem could be several places:
I may not have set up my project correctly
I may not have the file in the right place
I may not be using the syntax correctly
Here is the Cypher I've been using to try to load the file:
LOAD CSV WITH HEADERS FROM 'C:\Users\Diana\Documents\Nattosphere\Natto_Sample.csv' AS line
CREATE (n: Natto_Variety{Product_UID: line.Product_UID, Product_Manufacturer: line.Product_Manufacturer, Product_Weight_g: line.Product_Weight_g, Product_Flavoring: line.Product_Flavoring})
I've tried several approaches, and created a simplified file, but am getting the same error each time:
Invalid input 's': expected org$neo4j$cypher$internal$compiler$v2_2$parser$Strings$$HexDigit (line 1, column 33 (offset: 32))
"LOAD CSV WITH HEADERS FROM 'C:\Users\Diana\Documents\Nattosphere\Natto_Sample.csv' AS line"
At the bottom of the GUI, another error reads:
"Neo.ClientError.Statement.InvalidSyntax"
Any idea what might be happening here?

I think you have to do:
LOAD CSV WITH HEADERS FROM 'file:C:/Users/Diana/Documents/Nattosphere/Natto_Sample.csv'
If that doesn't work try:
LOAD CSV WITH HEADERS FROM 'file://C:\Users\Diana\Documents\Nattosphere\Natto_Sample.csv'
See: http://neo4j.com/developer/guide-import-csv/
Frist, you have to set true in setting dbms.security.allow_csv_import_from_file_urls
Second, you must to set where neo4J will search the csv in dbms.directories.import
When you setting those items, you have to copy you csv file into the folder where we set the dbms.directories.import
Later in Cypher:
LOAD CSV FROM 'file:///Natto_Sample.csv'
*if you hace folder into folder... use this character / to route your URL
The Syntaxe to load the csv with headers as described In the CSV Import Guide is :
LOAD CSV WITH HEADERS FROM "file-url" AS line
where the file-url , for local files, is :
file:///data.csv
Put the csv file in the import directory,and that should works
You don't need to write the C: reference:
LOAD CSV WITH HEADERS FROM 'file:/Users/Diana/Documents/Nattosphere/Natto_Sample.csv'
I want to use TextEdit to save data. what I have so far
tell application "TextEdit"
open /Users/UserName/Desktop/save.rtf
end tell
This gives me
"Expected “given”, “in”, “of”, expression, “with”, “without”, other parameter name, etc. but found unknown token."
and highlights the . in .rtf I tried removing the .rtf
but when I compile it it turns into
(open) / Users / username / desktop / (save)
This code gives "The variable Users is not defined."
also if possible can I have TextEdit run in the background without opening a window?
Put quotes around the path and use POSIX file to get a file object for the path:
tell application "TextEdit"
open POSIX file "/Users/UserName/Desktop/save.rtf"
end tell
You can modify the text of a document by changing the text property:
tell application "TextEdit"
set text of document 1 to text of document 1 & "aa"
end tell
It removes all styles in rich text documents. It also inserts the text as 12-point Helvetica in plain text documents, regardless of the default font.
Creating a new rtf file:
tell application "TextEdit"
make new document at beginning with properties {text:"aa"}
close document 1 saving in POSIX file "/tmp/a.rtf"
end tell
printf %s\\n aa | textutil -inputencoding UTF-8 -convert rtf -stdin -output a.rtf
