I want to search a text that contains comma in database, but, there is not comma in the reference.
For example. In database I have the following value:
"Development of computer programs, including electronic games"
So, I try to search the data using the following string as reference:
"development of computer programs including electronic games"
NOTE that the only difference is that in database I have a comma in the text, but, in my reference for search, I have not.
Here is my code:
public async Task<ActionResult>Index(string nomeServico)
{
using (MyDB db = new MyDB())
{
// 1st We receive the following string:"development-of-computer-programs-including-electronic-games"
// but we remove all "-" characters
string serNome = nomeServico.RemoveCaractere("-", " ");
// we search the service that contains (in the SerName field) the value equal to the parameter of the Action.
Servicos servico = db.Servicos.FirstOrDefault(c => c.SerNome.ToLower().Equals(serNome, StringComparison.OrdinalIgnoreCase));
}
}
The problem is that, in the database, the data contains comma, and in the search value, don't.
In you code you are replacing "-" with "" and that too in your search string. But as per your requirement you need to change "," with "" for your DB entry.
Try doing something like this:
string serNome = nomeServico.ToLower();
Servicos servico = db.Servicos.FirstOrDefault(c => c.SerNome.Replace(",","").ToLower() == serNome);

I'm porting my Swift app to Flutter and for localising it I'm following this https://github.com/billylev/flutter_localizations but I can't see how to insert placeholder to insert a value in the translated values.
Basically the guide uses
String text(String key) {
return _localisedValues[key] ?? "$key not found";
}
to get the corresponding key:value pair from a .json file as
{
"Shop": "Negozio",
}
I just pass it in the Textwidget as :
Text(AppLocalizations.instance.text('Shop')).
How to modify text to insert one or more placeholders and how would be the .json be constructed?
Say for the value "User": "User" I'd like to insert a value after the transaction I can simply use a string sum and add the value as `Text(
AppLocalizations.instance.text('User') + ' ${widget.user.name}', but if I need to insert a value in the middle of the translated sentence, eg a message, I don't see how to accomplish it.
I need it to make localised versions of incoming push notification, and they have args.
In Swift I have it like this:
"ORDER_RECEIVED_PUSH_TITLE" = "Order number: %#";
"ORDER_RECEIVED_PUSH_SUBTITLE" = "Shop: %#";
"ORDER_RECEIVED_PUSH_BODY" = "Thank you %#! We received your order and we'll let you know when we start preparing it and when it's ready. Bye";
Any suggestions on how to accomplish that in Flutter?
Many thanks
I was suggested this package https://pub.dev/packages/sprintf#-installing-tab- and it works just as I needed. Sprintf just lets you specify one or more placeholders in a String and pass an array of args.
https://developermemos.com/posts/using-sprintf-flutter-dart. for more info, even this is pretty much it. So for example
"ORDER_RECEIVED_PUSH_TITLE" = "Order number: %#";
in the .json file would be :
{
"ORDER_RECEIVED_PUSH_TITLE": "Oder number: %s"
}
and using it would be
String orderNumber = 'some uuid';
Text(Sprintf(AppLocalitazions.instance.text('ORDER_RECEIVED_PUSH_TITLE'),[orderNumber]);
Hope this helps others.
I have this string: "C:\Procesos\rrhh\CorteDocumentos\Cortados\10001662-1_20060301_29_1_20190301.pdf" and im trying to get this part : "20190301". The problem is the lenght is not always the same. It would be:
"9001662-1_20060301_4_1_20190301".
I've tried this: item.ToString.Substring(66,8), but it doesn't work sometimes.
What can I do?.
This is a code example of what I said in my comment.
Sub Main()
Dim strFileName As String = ""
Dim di As New DirectoryInfo("C:\Users\Maniac\Desktop\test")
Dim aryFi As FileInfo() = di.GetFiles("*.pdf")
Dim fi As FileInfo
For Each fi In aryFi
Dim arrname() As String
arrname = Split(Path.GetFileNameWithoutExtension(fi.Name), "_")
strFileName = arrname(arrname.Count - 1)
Console.WriteLine(strFileName)
Next
End Sub
You could achieve this using a simple regular expressions, which has the added benefit of including pattern validation.
If you need to get exactly eight numbers from the end of file name (and after an underscore), you can use this pattern:
_(\d{8})\.pdf
And then this VB.NET line:
Regex.Match(fileName, "_(\d{8})\.pdf").Groups(1).Value
It's important to mention that Regex is by default case sensitive, so to prevent from being in a situations where "pdf" is matched and "PDF" is not, the patter can be adjusted like this:
(?i)_(\d{8})\.pdf
You can than use it directly in any expression window:
PS: You should also ensure that System.Text.RegularExpressions reference is in the Imports:
You can achieve it by this way as well :)
Path.GetFileNameWithoutExtension(Str1).Split("_"c).Last
Path.GetFileNameWithoutExtension
Returns the file name of the specified path string without the extension.
so with your String it will return to you - 10001662-1_20060301_29_1_20190301
then Split above String i.e. 10001662-1_20060301_29_1_20190301 based on _ and will return an array of string.
Last
It will return you the last element of an array returned by Split..

I'm trying to read from a Word document and I want the computer to tell me what is written in document not to write itself in other place. So when I say the keyword "word" my program should open a dialog menu and let me to select a word file and tell me what is inside. The other keywords work. So here's my code and also my error.
case "word":
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
object readFromPath = null;
Document doc = app.Documents.Open(ref readFromPath);
foreach (Paragraph objParagraph in doc.Paragraphs)
ss.SpeakAsync(objParagraph.Range.Text.Trim());
((_Document)doc).Close();
((_Application)app).Quit();
}
And my error is enter image description here
Application.Documents.Open takes the full path and filename.
The path must end with \ and prefix the string with # (or leave out the # and double the backslashes \ as one backslash is considered to be an escape character)
object readFromPath = #"C:\Users\N.Horatiu\Desktop\s.docx"
Document doc = app.Documents.Open(ref readFromPath);
I have large list of email addressses from a file. It comes around 1 million email ids. I have list of bad words like spam,junk etc, it consist of 20,000+ bad words.
I need to validate email ids. If bad words is present any where in email id it will be marked as invalid.
For example;
testspam#gmail.com - invalid
newuser#desspam.com - invalid
I would like to know which will be fastest comparison method as array looping will take time.
I tried following methods
//$keyword_list- array of bad words;
//$check_key- the email id which need to validate
$arrays = array_chunk($keyword_list, 2000);
for($i=0;$i<count($arrays);$i++)
{
if (preg_match('/'.implode('|', $arrays[$i]).'/', $check_key, $matches)){
return 1;
}
}
The above method is taking more time when comparing 1 million data.
Next we tried with the following code and this also takes more time
//$contain = bad words separated by '|'
// $str - the email id which need to validate
if(stripos($contain,"|") !== false)
{
$s = preg_split('/[|]+/i',$contain);
$len = sizeof($s);
for($i=0;$i < $len;$i++)
{
if(stripos($str,$s[$i]) !== false)
{
return(true);
}
}
}
if(stripos($str,$contain) !== false)
{
return(true);
}
return(false);
Finally I had tried Mongodb Text Search. It works fast with the following issues
If 'Hell' is the word in my bad list and my email id is like
head#e-hellinglysussex.sch.uk, then the Mongodb Text Search wont matches it.
Here is the code I used;
$ret = $db->command( array("text" =>$section, "search" => $keyword_string, "limit"=>$cnt_finalnonmatch));
where $section = Collection name,
$keyword_string = Comparing keywords string separated by space, for eg "Hell Spam Junk" etc,
$cnt_finalnonmatch = total number of comparing email ids
Please help me to solve this issue.
I am not entirely sure, but I suspect that the problem is that 'Hell' is not equal to 'hell' when you search for text since mongodb is case sensitive.
The solution should be to force all the strings and word to be lowercase (or uppercase)
We have used Mongodb 'like' to solve this issue;
$keywords = $key['keyword']; // Keywords need to compare
$regexObj = new MongoRegex("/".$keywords."/i"); // MongoRegex function declration
$where = array($section => $regexObj); // $section is the collection name
$resultset = $info->find($where);
I am using Zend Lucene Search:
......
$results = $test->fetchAll();
setlocale(LC_CTYPE, 'de_DE.iso-8859-1');
Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8());
foreach ($results as $result) {
$doc = new Zend_Search_Lucene_Document();
// add Fields
$doc->addField(
Zend_Search_Lucene_Field::Text('testid', $result->id));
$doc->addField(
Zend_Search_Lucene_Field::Keyword('testemail', strtolower(($result->email))));
$doc->addField(
Zend_Search_Lucene_Field::Text('testconfirmdate', $result->confirmdate));
$doc->addField(
Zend_Search_Lucene_Field::Text('testcreateddate', $result->createddate));
// Add document to the index
$index->addDocument($doc);
}
// Optimize index.
$index->optimize();
// Search by query
setlocale(LC_CTYPE, 'de_DE.iso-8859-1');
if(strlen($Data['name']) > 2){
//$query = Zend_Search_Lucene_Search_QueryParser::parse($Data['name'].'*');
$pattern = new Zend_Search_Lucene_Index_Term($Data['name'].'*');
$query = new Zend_Search_Lucene_Search_Query_Wildcard($pattern);
$this->view->hits = $index->find(strtolower($query));
}
else{
$query = $Data['name'];
$this->view->hits = $index->find($query);
}
............
Works fine here:
It works when I give complete word, first 3 character, case insensitive words
My issues are:
When I search for email, i got error like "Wildcard search is supported only for non-multiple word terms "
When I search for number/date like "1234" or 09/06/2011, I got error like "At least 3 non-wildcard characters are required at the beginning of pattern"
I want to search date, email, number here.
In file zend/search/Lucene/search/search/query/wildcard a parameter is set,
private static $_minPrefixLength = 3;
chnage it and it may work..!
Based on NaanuManu's suggestion, I did a little more digging to figure this out - I posted my answer on a related question here, but repeating for convenience:
Taken directly from the Zend Reference documentation, you can use:
Zend_Search_Lucene_Search_Query_Wildcard::getMinPrefixLength() to
query the minimum required prefix length and
use Zend_Search_Lucene_Search_Query_Wildcard::setMinPrefixLength() to
set it.
So my suggestion would be either of two things:
Set the prefixMinLength to 0 using Zend_Search_Lucene_Search_Query_Wildcard::setMinPrefixLength(0)
Validate all search queries using javascript or otherwise to ensure there is a minimum of Zend_Search_Lucene_Search_Query_Wildcard::getMinPrefixLength() before any wildcards used (I recommend querying that instead of assuming the default of "3" so the validation is flexible)
