php - Replace string with a particular format -


मेरे पास निम्न प्रारूप के साथ एक स्ट्रिंग है, 

  some_string% value1: value2: value3 :% Some_anather_string% value4: मान 5: मान 6:%   
 मुझे % value1: value2: value3:%  और % value4: value5 को निकालना होगा: मान से 6:%  स्ट्रिंग से, मेरा मतलब है कि मुझे %  के साथ आरंभ करने के प्रारूप के साथ :%  और किसी भी स्ट्रिंग को :   
 क्या यह संभव है?  
 मैं  str_replace ()  के साथ कोशिश करता हूं, लेकिन यह केवल हम ही मूल्यों को जानते हैं।   "post-text" itemprop = "text"> 
 इस सरल regex का उपयोग करें  
  $ echo $ preg_replace ("~ % (। *?):% ~ "," ", $ Str);

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

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? ...
