Android - Disable Text Selection

In order to disable text selection in a WebView we can use following approaches: CSS * { user-select: none; -moz-user-select: -moz-none; -khtml-user-select: none; -webkit-user-select: none; } This approach will not work on all the versions of Android as the support was not there till late. Handling LongClick public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); WebView webView = (WebView) this.findViewById(R.id.webView1); webView.loadData("<html><head><style>head><body>You scored <b>192</b> points.</body></html>", "text/html", null); webView.setOnLongClickListener(new View.OnLongClickListener() { public boolean onLongClick(View v) { return true; } }); }

Split String in C++ with delimiters

In order to split string in c++ we can use strtok(). A sequence of calls to this function split str into tokens, which are sequences of contiguous characters separated by any of the characters that are part of delimiters. On a first call, the function expects a C string as argument for str, whose first character is used as the starting location to scan for tokens. In subsequent calls, the function expects a null pointer and uses the position right after the end of last token as the new starting location for scanning.

Convert std::string to char* and const char* - c++

Convert std::string to const char* std :: string name = "Anuj" ; const char * constName = name.c_str(); Convert std::string to char* std :: string name = "Anuj" ; const char * constName = name.c_str(); char * ptrToName = const_cast< char *> (name.c_str()); A simple progam #include <iostream> #include <stdio.h> using namespace std; int main() { std :: string name = "Anuj" ; const char * constName = name.c_str(); char * ptrToName = const_cast< char *> (name.c_str()); printf( "%s" ,constName); printf( "%s" ,ptrToName); cout << name << endl; return 0 ; }
