android - remove table rows except the first one - 


  सार्वजनिक रहित पॉप्युलेट () {TableRow tr = new tableRow (getActivity ()); tr.setId (100 + गिनती); Tr.setLayoutParams (नया लेआउटप्रर्म (लेआउट पैरामा.फिल_पैंट, लेआउट पैरा। WRAP_CONTENT)); बटन b_add = नया बटन (getActivity ()); b_add.setId (20); b_add.setText ( "+"); b_add.setTextColor (Color.RED); b_add.setGravity (Gravity.CENTER); B_add.setPadding (2, 2, 2, 2); b_add.setOnClickListener (जोड़ने); tr.addView (b_add); TextView v_no = नया संपादन टेक्स्ट (getActivity ()); V_no.setId (200 + गणना); V_no.setHint ("वाहन नहीं"); v_no.setTag ( "पता"); v_no.setTag ( "v_no"); v_no.setTextColor (Color.BLACK); v_no.setGravity (Gravity.CENTER); tr.addView (v_no); बटन b_minus = नया बटन (getActivity ()); b_minus.setId (20); b_minus.setText ( "-"); b_minus.setTextColor (Color.RED); b_minus.setGravity (Gravity.CENTER); B_minus.setPadding (2, 2, 2, 2); b_minus.setOnClickListener (निकालने के लिए); tr.addView (b_minus); // अंत में इसे टेबल पंक्ति tl.addView (tr, नया TableLayout.LayoutParams (LayoutParams.FILL_PARENT, लेआउट पैरा। WRAP_CONTENT) में जोड़ें); गिनती ++; }   
 मैं टेबल लेआउट का उपयोग करते हुए तीन कॉलमों के साथ एक टेबल बनाने के लिए इस कोड को बना देता हूं। यह ठीक काम करता है.लेकिन मुझे पहली पंक्ति को छोड़कर टेबल पंक्तियाँ निकालने की जरूरत है.क्या मैं आपकी मदद कर सकता हूं कि   
 
 
  जबकि (yourTableLayout.getChildCount () & gt; 1) yourTableLayout.removeView (yourTableLayout GetChildAt (yourTableLayout.getChildCount () - 1);   
 यह आपके  TableLayout  पर पुनरावृत्त होना चाहिए और पंक्तियों को एक से ऊपर से ऊपर तक एक पंक्ति में निकाल देना चाहिए, तब तक वहाँ सिर्फ एक है (जो हटाया नहीं जाएगा)।

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? ...
