html - How can I create a DIV that's located in the center of my browser screen? -


मैंने निम्नलिखित की कोशिश की: 

  & lt; body style = "height: 100%; "& gt; & Lt; div शैली = "प्रदर्शन: ब्लॉक; ऊंचाई: 30rem; चौड़ाई: 100rem; मार्जिन: ऑटो;" & gt; एक्स & lt; / div & gt; & Lt; / body & gt;   
 ऐसा क्या होता है कि बॉक्स सही दाएं और बाएं मार्जिन के साथ केंद्रित होता है लेकिन ऊपर और नीचे में कोई मार्जिन नहीं लगता है। नोट 1rem के बारे में 10px के बराबर है, इसलिए ऊपर और नीचे पर बहुत सारे स्थान होना चाहिए। हालांकि, DIV सिर्फ स्क्रीन के शीर्ष पर बैठता है।   
 
 
 इसी तरह:  
  #yourdiv {स्थिति: तय; ऊंचाई: 18em; मार्जिन-टॉप: -9em; मार्जिन-बाएं: -15 एएम; सीमा: 1px ठोस # सीसीसी; पृष्ठभूमि रंग: # एफ 3 एफ 3 एफ 3; शीर्ष: 50%; बाएं: 50%; चौड़ाई: 30em; }

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? ...
