I have found an old site that is displaying an error which is strange because it is untouched for a while Used to be. I get the following: Unable to go to line 0 on mysql result index 8 What is the reason for this and how should I fix it? This is a PHP / MySQL site. If I remember correctly, this error is usually like a code segment: // You probably have the same code as $$ var = mysql_result ($ result, 0, 'column_name'); Where either the query fails or the column is not present, check that $ result is a valid MySQL resource to ensure that SQL is valid , Then make sure that you are actually getting results from the database before calling mysql_result . Or, even better, use mysql_fetch_array instead of getting every column value manually (if many columns are returned from your query).

I am not posting my exact problem in order to avoid space sake and confusion, but instead of identifying one I In the Python, print the sequence of numbers backwards. Restraint is that I should use recursion, and I should not have any local variables inside my function. For example, if the number 8 is given for the given function, then I want to print it 1,2,4,8. Also assume that the input is an integer, please. def function (x) If (x! = 1) x = x / 2 I have dispelled my mind for a while, But I can not find anything that will actually print the final value (i can only achieve it to output 1,2,4) def function (x) if (x! = 1) x = x / 2 function (x) print x, code above 1,2,4 Prints, given that x is 8 in the beginning. However, if I put a recursive call anywhere in front of the "x = x / 2" line, then the value of x is constant 8 How can I accomplish everything I am trying to do? I'm sure there is something simple that I see, but I do not know how it is.

First of all, this question really proves to be a lot for me for a Stackoverflow post requirement. However, after executing several Google searches for information, I was lost while trying to learn about Couchbase . In Couchbase (I'm using 2.2 Community Edition), how do I share ideas among developers? Is import / export functionality available? If not, what does the purpose of Couchbase mean for developers to share ideas that are used without manual copy / paste? It is clear that the code, which will be written by a development team for the question of Couchbase, will require the correct visual names. How can it be possible to develop a Couchbase DB with a Couchbase locally as a team without having to send a view file to the developer? I'm sorry, if I'm a bit disappointing or harsh here, but if it's not possible to share ideas between many developers, then I do not know that developers trying to share Couchbase database configuration How to be a viable DB solut

I, in some smart signal class desiccator, have declared the member variable within a class to free this interface The code, which is better, is: Members varible CComQIPtr & lt; IMyInterFace & gt; m_pMyInterface; constructor m_pMyInterface.CreateInstace (CLSID_MyInterface); Destructive in if (m_pMyInterface) m_pMyInterface.Release (); Or should it be if (m_pMyInterface.p = zero!) M_pMyInterface.Release (); The above form which is a better one and the way I am using interface pointsers there is a flaw. Tom ~ CComQIPtr The Destructor takes care of everyone to explicitly release you There is no need to do so, if you want, to reuse the variable, you can do either of the two: m_pMyInterface.Release (); m_pMyInterface = Zero; With zero (operator = CComPtr , with CComQIPtr may be unclear) Works) check is not required, the CComQIPtr :: release method does this anyway.

I'm testing the GUI possibilities using QtQuick and QML, but I'm looking for information in implementing the GLSL shadow effect The problem is happening in the window itself, for example, suppose I want to create a full-screen application that simply blocks everything behind the window; As you move the application window in front of your desktop, everything behind the window will be affected by the shader, and if you maximize the app, the whole screen will be affected. In the official QtQuick5.2 documentation, they specify to apply an image element to do so, they make a version and use the image from the id. I have tried to mention the 'id' property of my 'window' QML element, but it does not work (the result is in a black window because the shader fails to process properly). There are also modules in which some good effects are produced, but I do not have much luck to apply those effects on the window. So, with QtQuick2.2 and QML, is there any way to &#

I am working in Rail application and need a solution below. I am taking some time consuming processes in the background using the Sidekiq and saves related information in the database. Now when each process is completed, we will get the Would like to show the notification in a different area that the process is complete . Therefore, the information sector needs to actually pull things from the back (this information area will be available in every page) and show it dynamically, I thought Ajax should be an option . But, I do not know how to trigger it for a particular area or there is another option through which the client can efficiently obtain dynamic content from the server without much traffic. I know that this will be a broad topic that tells about it. But any relevant information will be appreciated.

A more advanced and flexible way is to change a little HTML structure so that the value of a is inside the panel and then add display: block Instead of setting the width and height you can use percentages, because the size of the clickable zone handles the panel. with fixed size.

When I run 'Select from the table' on an INNODB table, does the table lock become insensitive? Does this mean that during the time, MySQL takes the result set back, can not I issue an update statement in the table? The entire table will be locked in shared mode as I have understood, until the result is not returned to the set, the update command can be executed only after that. INADB uses a feature. Locking in shared mode is not necessary, because MVCC will keep the version of the previous version of your SELECT statement if necessary Be able to Then the answer is 'no', while updating a SELECT statement, there will be no need to lock a row while updating. This is, as long as this particular SELECT statement like SELECT .. FOR UPDATE is.

Thanks private random random; Public Zero Mouse Mouse Pressed (MouseWave E) {Boolean Hit: Results = Fixed Hate (); If (hitResult) {// actual display //} else {// display false} // private boolean fixed hit () {random.nextBoolean (); } Since a if () requires a Boolean result, then the == true lies in it, obviously Code is not required Just make sure that you have done the random in the constructor for an example before using it.

The Bwlow code is increasing the brightness of the entire screen but I am taking a special area in XML (like taking a 100 * linear layout * 100), and I do not want to increase the brightness of that particular (linear layout) area only on the whole screen I am getWindow () SetAttributes (l); WindowManager.LayoutParams l = getWindow (). GetAttributes (); Lll8.screenBrightness = 1.0f; . GetWindow () setAttributes (L); Use two layouts and set two different alpha values ​​for them so that different brightness Levels can be achieved by a single screen. Another way is to use the gradient texture (shade with color in color, which you want less brightness), place it in a drawer folder and insert it in XML and align it on top mother-father. Hope you have code to set the brightness.

Jeffile Chupper Selector = new Jeffile Closer (); Filef = new file ("C: /"); File named; File namespace; Chooser.setCurrentDirectory (F); Chooser.showOpenDialog (zero); Chooser.setDialogTitle ("Choose File to Play"); Chooser.setApproveButtonText ("Play"); Named = chooser.getCurrentDirectory (); Namepath = chooser.getSelectedFile (); System.out.print ("The name of the directory is" + nomir.getName ()); System.out.print ("The name of the path is" + namepath.getAbsolutePath ()); And here is the code for my menu JFrame frame = new jframe ("menu

Is it possible that 2 controllers such as DispatherServet in Spring MVC write more than one time when we develop spring MVC applications Are there. Yes .. !! it's possible. You must set a @RequestMapping annotation at the class level, the value of that annotation will be the prefix of all the requests that come with that controller. Example: For 1 admin: @controller @ request mailing ("test") public class test controller {} < / Code> For the second controller: @Controller @RequestMapping ("demo") public class DemoController {} If there are different / different methods of the two controllers, then you can reach & lt; Your server & gt; / Test / & lt; Request Method Mapping & gt; & Lt; Your server & gt; / Demo / & lt; Request Method Mapping & gt;

My question is very common..and its not a duplicate .. When we like something Announce this as int mat [1000000] [1000000]; It is certain that this will give an error by saying the matrix size is too big. I have seen many problems on many competitive programming websites where we need to declare a 2D matrix with 10 ^ 6 rows, columns, I know that to reduce the matrix size, always its There are some tricks attached to it. That's why I just want to ask what can we do in the case of possible ways or tricks to reduce the size in such cases .. This means what type of algorithm is like a DP or someone else Need to solve ?? int mat [2] [1000000]; Code>. After calculating the existing row, you can immediately leave the previous row and switch the current and the previous. Sometimes, it is possible to use the std :: map instead of the 2D array. I have got many questions in programming competitions and the solution is substituted on a case-by-case basis, so if you

It does not run and there are no error messages. The home / pi / python_games / image.png is called from image.png . Obviously one solution would be to give these resources a complete path, but the Python program calls other dragon programs in their directories, which also have relative paths, and I do not want to change them all. Any You change your existing working directory inside Before the script you start making your relative import calls, use os.chdir ("the complete path to where your script remains").

On the form I have a set of fields which can increase the number of user numbers (i.e. they can add more to the same type of fields), and therefore I need to set this script which handles submitted data is. So far I have it: while ($ i & lt; = $ totalproducts) {$ product. $ I = $ _POST ['Product' $ I]; $ I ++; } $ Totalproducts holds the total number of areas As an example, let me assume that I have 3 items, I want to get it from the code: < Pre> $ product1 = $ _POST ['product1']; $ Product2 = $ _POST ['product2']; $ Product3 = $ _POST ['product3']; I'm sure that I am near, just can not do it together slots ... You can use: while ($ i & lt; = $ totalproducts) {$ variable = 'Product' $ I; $$ variable = $ _POST ['product' $ I]; $ I ++; } But better use will be ARAR: $ products = array (); While ($ i & lt; = $ totalproduc

The only advantage is that in "Big Objects", it is that you can access parts of binary data through a streaming interface. Rarely you will need images

Can someone tell me whether it is possible to have a column in MYSQL in the table, which is automatically assigned to a given device For SUM function does the number of columns As a comparative example in Microsoft Excel, it is possible to have a cell that SUM functions for cells of a particular category and automatically updates ie (= SUM E4 : E55) Is there a column that gets the same function in MYSQL? To expand more - I have several types of columns that are related to different sizes of our products i.e., quantity_size _ * and want A column that will be the value of the quantity column and automatically updates if any price has changed. Any advice will be great thanks Normally you can do this Do not fly-in-fly and do not store them in your chosen query. select some_calumn, col1 * col2 as your_table some_calculation_result but if you have a good reason to do so, then you can use it Triggers to calculate those data. You need an Update Trigger to capture

When an MSNodeSQL query fails, I'm confused with callback arguments. I am new to JavaScript, so this is a simple JavaScript Problems can be there. The database is a simple query: conn.query (stored procedure, parameter, function (error, result) {if (err) {console.log ("err =" + err); Console Log ("err =" + JSON.stringify (mistake));}}); I have given the name of a stored procedure, so it will not be found and an error will be compelled. The logic of the error shows a meaningful description of the error: err = Error: [Microsoft] [SQL Server Native Client 11.0] [SQL Server] stored procedure 'dbo.me3_MsgQueueIn_AddMessage'. When I return this variable to the customer and show it in a browser which it appears as a JSON object and when I display it on the server as shown above , Then it is a JSON object and I see err = {"sqlstate": "42000", "code": 2812} Such a typical error code is also good for a meaningful
