javascript - Regex validation doesn't work as expected - 


  var मान्य करें पासवर्ड = समारोह (पासवर्ड) {var ऊपरी = नया RegExp (/ ^ (? =। * [AZ ])। $ $ /), निचले = नया रेगएक्स (/ ^ (? =। * [एजी])। $ $), प्रतीकों = नया रेगएक्स (/^( ??=.*(_ | [^ \ w] ))। $ $ /), संख्याएं = नया रेगएक्स (/ ^ (? =। * \ d)। + $ /); ((Upper.test (पासवर्ड) & amp अगर; & amp; lower.test (पासवर्ड)) || (upper.test (पासवर्ड) & amp; & amp; numbers.test (पासवर्ड)) || (upper.test (पासवर्ड) & amp ; & Amp; symbols.test (पासवर्ड)) || (लोअर.test (पासवर्ड) & amp; amp; amp; और amp; संख्या। टीएस्ट (पासवर्ड)) || (लोअर। टेस्ट (पासवर्ड) & amp; amp; प्रतीक। टीएस्ट (पासवर्ड) ) {वापस सच; } Else {alert ('अमान्य पासवर्ड')}} मान्य पासवर्ड ('Foo1!'); });   
 यह केवल वापसी सच किसी भी मूल्य दर्ज किया गया है, तो अगर मैं केवल यह रिटर्न एक दर्ज मुझे सच   
 
 
 अपनी टिप्पणी मैं अपने जवाब को नवीनीकृत किया है के आधार पर:  
  पासवर्ड  4 से बाहर  कम से कम दो  पर से मेल खाना चाहिए  true    
  var validatePassword = function (password) {var numero के लिए  और  8 अक्षर  है) = 0; // चेक अगर कोई अंक मौजूद है तो यदि (/ (? =। *? [\ d])। * $ / test (पासवर्ड)) {numero ++; } // जांचें कि यदि अपरकेस अक्षर मौजूद है तो यदि (/ (? =। * * [A-Z])। * $ /। परीक्षण (पासवर्ड)) {numero ++; } अगर एक छोटा अक्षर मौजूद है की जाँच // अगर (/ (= * [a-z]) * $ / परीक्षण (पासवर्ड)?।?।।) {न्यूमरो ++; } अगर विशेष वर्ण मौजूद है की जाँच // अगर (/(?=.*?(_ | [^ \ w])) * $ / परीक्षण (पासवर्ड)) {न्यूमरो ++।। } // जांचें कि यदि कम से कम 8 अक्षर उपस्थित हैं तो (/^( ????=.{8,}).*$/.test(password)) {var लंबाई = सच; } अगर (संख्या & gt; = 2 & amp; लंबाई) {चेतावनी ('मान्य पासवर्ड'); console.log (न्यूमरो); वापस सच; } और {चेतावनी ('अमान्य पासवर्ड'); console.log (न्यूमरो); }} मान्य पासवर्ड ('foo4ogD!');

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
