  • if not (i_ReLaunch = 1 and (dt_enddate is not null)) How this epression will be evaluated in Oracle

    - by Phani Kumar PV
    if not (i_ReLaunch = 1 and (dt_enddate is not null)) How this epression will be evaluated in Oracle 10g when the input value of the i_ReLaunch = null and the value of the dt_enddate is not null it is entering the loop. according to the rules in normal c# and all it should not enter the loop as it will be as follows with the values. If( not(false and (true)) = if not( false) =if( true) which implies it should enters the loop But it is not happening Can someone let me know if i am wrong at any place

  • writing code for nm-alike command [C++]

    - by Neeraj
    Hi everyone! Out of curiosity about reverse engineering, I am thinking of writing a simple program (in C++) that takes an executable as input and produces the names of all the functions that were a part of source program of that executable. Any pointers on how should I go about it? Step-by-step approach would be much appreciated!

  • What happens if I give more inputs in estimateRigidTransform or getAffineTransform?

    - by user3531608
    I am using estimateRigidTransform with about two vectors of 100 points and is working FINE. But somehow getAffineTransform doesn't work. I know that findHomography finds the best matrix using RANSAC and getPerspectiveTransform needs only 4 points. My question is what happens if I give more inputs in estimateRigidTransform or getAffineTransform? Does it take only 4 points from input matrix? Or do some kind of RANSAC?

  • How to merge multiple arrays in pairs

    - by user3688059
    I have a problem with "pairing" arrays into one (by index). Here is an example: INPUT: inputArray = [ [0, 1, 2, 3, 4], [2, 3, 5, 7, 8], [9, 6, 1] ] OUTPUT: outputArray = [ [0,2,9], [1,3,6], [2,5,1], [3,7,chooseRandom()], [4,8,chooseRandom()]] Questions: 1) How to avoid out of range problem 2) How to write chooseRandom() to choose N neighbour I'm using python but feel free to share your thoughts in any language.

  • ms-access: designing a report: printing text on specific x,y coordinates

    - by every_answer_gets_a_point
    i need to design a report that will print text on specified x,y coordinates for example, i will input (50,50), (60,60), (70,70) and i will have my program print text at those specific coordinates on the report. in total there will be about 50 different coordinates. how do i achieve this? should i be using a label control or a textbox? should i be creating the controls dynamically or should i already have controls set at the specified regions?

  • Terminating a long-executing thread and then starting a new one in response to user changing parameters via UI in an applet

    - by user1817170
    I have an applet which creates music using the JFugue API and plays it for the user. It allows the user to input a music phrase which the piece will be based on, or lets them choose to have a phrase generated randomly. I had been using the following method (successfully) to simply stop and start the music, which runs in a thread using the Player class from JFugue. I generate the music using my classes and user input from the applet GUI...then... private playerThread pthread; private Thread threadPlyr; private Player player; (from variables declaration) public void startMusic(Pattern p) // pattern is a JFugue object which holds the generated music { if (pthread == null) { pthread = new playerThread(); } else { pthread = null; pthread = new playerThread(); } if (threadPlyr == null) { threadPlyr = new Thread(pthread); } else { threadPlyr = null; threadPlyr = new Thread(pthread); } pthread.setPattern(p); threadPlyr.start(); } class playerThread implements Runnable // plays midi using jfugue Player { private Pattern pt; public void setPattern(Pattern p) { pt = p; } @Override public void run() { try { player.play(pt); // takes a couple mins or more to execute resetGUI(); } catch (Exception exception) { } } } And the following to stop music when user presses the stop/start button while Player.isPlaying() is true: public void stopMusic() { threadPlyr.interrupt(); threadPlyr = null; pthread = null; player.stop(); } Now I want to implement a feature which will allow the user to change parameters while the music is playing, create an updated music pattern, and then play THAT pattern. Basically, the idea is to make it simulate "real time" adjustments to the generated music for the user. Well, I have been beating my head against the wall on this for a couple of weeks. I've read all the standard java documentation, researched, read, and searched forums, and I have tried many different ideas, none of which have succeeded. The problem I've run into with all approaches I've tried is that when I start the new thread with the new, updated musical pattern, all the old threads ALSO start, and there is a cacophony of unintelligible noise instead of my desired output. From what I've gathered, the issue seems to be that all the methods I've come across require that the thread is able to periodically check the value of a "flag" variable and then shut itself down from within its "run" block in response to that variable. However, since my thread makes a call that takes several minutes minimum to execute (playing the music), and I need to terminate it WHILE it is executing this, there is really no safe way to do so. So, I'm wondering if there is something I'm missing when it comes to threads, or if perhaps I can accomplish my goal using a totally different approach. Any ideas or guidance is greatly appreciated! Thank you!

  • C# WPF XAML Loading

    - by user3713589
    Hi I'd like to inquire on how i can load a WPF Xaml into code so that I can change the values of the attributes of some XAML elements and output it by creating another XAML files. This is so that I can output the same file with values dynamically input by the user. the XamlReader.Load() method cannot be used; it will throw an exception (because they are unable to recognise Window as the root element). I'm using VS2013 and C#.

  • How to determine when the text of an html element is changed

    - by Micah
    I have an error message like this: <span class="errorMessage">Your input sucks!</span> and I need to determine when it changes. the validation framework I'm using sets the text when there's an error and removes it when it's complete. I'm hoping to tap into that by watching for changes to the text property of the element using jquery. Any idea of how to go about doing this? Thanks!
