java - How to check if a string contains two asterisk characters? -

-

हमारे पास एक स्ट्रिंग इनपुट है और निम्न संयोजन मान्य हैं (जैसे sunday , * रवि * * , सूर्य * दिन * , * सूर्य * दिन , सु * nda * y ) अगर इसमें केवल एक सिंगल तारांकन चिह्न, तो यह एक खराब इनपुट है।

इसलिए उपरोक्त इनपुट को देखते हुए, मैं यह कैसे देखूं कि स्ट्रिंग में कई एस्टेरिस्क हैं।

String.matches का उपयोग कर सकते हैं: 

  "^। * (?: \" Post-text "itemprop =" text "> 
 \ *। *) {2} $ "

यदि आप चाहते हैं बिल्कुल दो तारांकन: 

 " ^ [^ * ] * (?: \\ * [^ *] *) {2} $ "

हालांकि इस कार्य के लिए स्ट्रिंग पर दोबारा चलना और तारांकन गिनना आसान हो सकता है। / P>

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

session - security issue: php login/logout script + back button -

-
I am using a login script that stores session value $ _ Session ['Login' '] =' Yes' On logout, when the user enters the correct user / password, this session value is set to an empty space. However users can back up and log back in for some time. I also tried $ _SESSION = array (); And session_destroy (); But with the same result. Does they actually log back in, or do they reload pages only Cache? If it's only a cache, they will not be able to see the page that was not before, and they will not be able to see new data on your site. If they are actually logging back in, then your login code is bad on each page on the login page and login page.
