Now it is returning nothing in Body tag. Is selenium not loading page? 2 Answers 2 Do you require the HTML tags also? If not, you can try retrieving using the body tag. Here's how I would do it using Java. String src=driver.findElement(By.tagName("body")).getText(); As per t...

Is there distinction between the commands understood by the MySQL client and understood by the MySQL server?

Image
Clash Royale CLAN TAG #URR8PPP Is there distinction between the commands understood by the MySQL client and understood by the MySQL server? When using MySQL in command line (such as Bash), is there a similar distinction between PostgreSQL server and client psql? If yes, what are the MySQL client and MySQL server when I run mysql in a OS shell? I never see in MySQL document a distinction between MySQL client/shell and MySQL server. mysql is there distinction between the commands understood by the MySQL client and understood by the MySQL server? For comparison, in Postgresql, psql has its own commands usually started with , such as l , while postgresql server only understands SQL commands and doesn't understand psql commands. In MySQL official document, I don't find it mentions whether a command is only understood by the MySQL client or by the MySQL server. l Thanks. 1 Answer 1 The command line client mysql also has commands that are interpreted by the client program ...

Java interface implementation?

Image
Clash Royale CLAN TAG #URR8PPP Java interface implementation? I'm newbie to Java. I would like to ask different between the following interface examples? public interface MyInterface public void doSomething(); like this public class MyClass implements MyInterface public void doSomething .... and this public class MyClass implements MyInterface protected MyInterface myInterface; public MyClass (MyInterface myInterface) this.myInterface = myInterface; public void doSomething () myInterface.doSomething(); why would you want to do it the second way? How would you create an MyInterface to pass to your constrcutor? What would any benefit be? – Scary Wombat Aug 8 at 4:24 MyInterface Interface can have multiple implementations. Therefore it is possible to get different implementation calls at runtime – Jude Niroshan Aug 8 at 4:25 5 Answers 5 public class MyClass implements MyInterface public void doSomething ....

Untiy , how to disable log message from google play game service plugin

Image
Clash Royale CLAN TAG #URR8PPP Untiy , how to disable log message from google play game service plugin These log message are so annoying. It show every time i hit play button on Unity. How to disable it? if you double click on the log does it take you to the source file where a debug.log is called? if so just comment it out/delete it. If it doesn't and its tucked away in some dll then i don't think you can do a whole lot about it – remy_rm Aug 8 at 8:16 @remy_rm i have tried double on it. it didn't go anywhere. – Tkaewkunha Aug 8 at 8:45 I'm afraid its packed into a .dll then, which you cannot edit unless you have the unpacked source code.. I don't think there is a way to stop these logs from showing up then. Someone may correct me on this. – remy_rm Aug 8 at 8:55 @remy_rm thank you. – Tkaewkunha Aug 8 at 9:08 @remy_rm Nope. There is a way to do so – Programmer Aug 8 at 14:28 By clicking "P...

XML Parsing Error - XmlHttpObj is null

Clash Royale CLAN TAG #URR8PPP XML Parsing Error - XmlHttpObj is null Since moving to a https server and updating code, I'm having problems with cascading dropdown boxes that were previously working. I get an XML Parsing Error: no element found, as well as an error telling me that XmlHttpObj.responseXML is null. I have had some errors relating to updating the mysqli sections, and from what I have been able to work out I think the problem might be with the query. However, this is the same query that I have been using, and which has been working fine. So, I'm really not sure what is wrong here. Ajax function causing error: function StateChangeHandler() // state ==4 indicates receiving response data from server is completed if(XmlHttpObj.readyState == 4 && XmlHttpObj.status == 200) populateCbo(XmlHttpObj.responseXML.documentElement); XML page which is returning the null value: <?php // simple data provider for a cascading dropdown Header("Content-type: ...

Code Comparison in Oracle DB and SVN

What do you mean with "Oracle DB files"? – Wernfried Domscheit Aug 8 at 6:18 Wernfried, our Schema SQL files or ddl files etc. – dhaval shah Aug 8 at 6:22 So as I have understand you have files on your machine and you want to check if they are on svn right ? so you can check out the scripts from svn localy to a folder then compare the 2 folder (there many free tool on the internet or you can develop a your own tool) the one are missing you put them in one folder then search fo there contents – Moudiz Aug 8 at 7:23 check out Never mention "Tool or script" in SO.

Segmentation Fault when allocating memory to a pointer to pointer variable [C] [closed]

Image
Clash Royale CLAN TAG #URR8PPP Segmentation Fault when allocating memory to a pointer to pointer variable [C] [closed] I'm trying to represent an array of strings by using a pointer to pointer. So I've defined char** arr as below: char** arr uint8_t lines = getLines(); char** arr = malloc (sizeof (char*) * lines); // char** arr = malloc (sizeof (char*) * ROWS_COUNT); In the debug process, the line above will be executed successfully and allocates memory to arr . The problem (and so, the error) issues when trying to allocating enough memory to hold a string within *(arr + 0) as below: arr *(arr + 0) // #define PATH_MAX 4096 *arr = malloc (sizeof (char) * (PATH_MAX + 1)); Runtime Error: Signal: SIGSEGV (Segmentation fault) Note: I've used casting operators (the first assignment by char** and the second one by char* ). It doesn't work too. char** char* Note: I've used ROW_COUNTS here for the sake of simplicity. In the original code, there is a lines variabl...

Idris Lightyear requireFailure does not do backtracking

Image
Clash Royale CLAN TAG #URR8PPP Idris Lightyear requireFailure does not do backtracking I want to parse a series of any 4 chars. However, these chars shouldn't form a specific string ( "bb" in an example below). So "aaaa" and "abcd" are okay, but neither "bbcd" nor "abbc" should not match. "bb" "aaaa" "abcd" "bbcd" "abbc" I composed a following parser: ntimes 4 (requireFailure (string "bb") *> anyChar) However, I noticed, that it "eats" single b chars. E.g. b parse (ntimes 4 (requireFailure (string "bb") *> anyToken)) "abcde" results in ['a', 'c', 'd', 'e'] (it fails, however, on "bbcd" and "abbc" as expected). ['a', 'c', 'd', 'e'] "bbcd" "abbc" As a workaround I used my own implementation of requireFailure : requireFailur...

Find Pythagorean triplet for which a + b + c = 1000

Clash Royale CLAN TAG #URR8PPP Find Pythagorean triplet for which a + b + c = 1000 A Pythagorean triplet is a set of three natural numbers, a < b < c, for which, a 2 + b 2 = c 2 For example, 3 2 + 4 2 = 9 + 16 = 25 = 5 2 . There exists exactly one Pythagorean triplet for which a + b + c = 1000. Find the product abc. Source : http://projecteuler.net/index.php?section=problems&id=9 I tried but didn't know where my code went wrong.
