  • how could it works if function is called before it is defined in python?

    - by user2131316
    I was wondering what does if __name__ == "__main__": really do in python, I have the following code in python3: def main(): test(); def test(): print("hello world " + __name__); if __name__ == "__main__": main(); we know that we have to declare a function before we use it, so function call inside of if part works fine, the main() is defined before it is called inside of if statement, but what about the test() function, it is defined after it is called and there is no errors: def main(): test(); def test(): print("hello world " + __name__); so how could it works if the test() function is defined after it is called?

  • (C++) If statement not effective

    - by Galileo
    void spriteput(int x,int y, int stype) { char sprite1[5]="OOOO"; char sprite2[5]="OOOO"; char sprite3[5]="OOOO"; char sprite4[5]="OOOO"; if (stype == 1) { char sprite1[5] = " OO "; char sprite2[5] = "OOOO"; char sprite3[5] = "OOOO"; char sprite4[5] = " OO "; mvprintw(2,y,"%s \n",sprite1); } mvprintw(x+1,y,"%s \n",sprite2); mvprintw(x+2,y,"%s \n",sprite3); mvprintw(x+3,y,"%s \n",sprite4); } If I'm correct that block of code should print out on a NCURSES screen OO OOOO OOOO OO Instead however, it prints out the default text (the first char statements). Can anyone tell me why this is? The "printw" statement inside the If-block prints out the proper text, so it's being assigned correctly. Thank you in advance.

  • OpenGL gluLookAt issues

    - by Chris D
    I am trying to switch my space invaders game to a first person view, i.e. a view of the world from the ship. I am getting a bit confused about what point I should be looking at. I am currently using these parameters in gluLookAt: GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glLoadIdentity(); GLU.gluLookAt(ship3dPos.x, ship3dPos.y, ship3dPos.z,400.0f, 600.0f,-50.0f, 0.0f, 1.0f,-0.0f); Where ship3dPos is a Vector3f. I'm not sure what I'm supposed to set parameters 4,5 and 6 to, to get a view of the whole world(window is 800/600). I want to have a view of say 100.0 wide from the ships perspective, with this view moving along the x-axis as the player moves the ship. Thanks

  • Out of Memory Matlab Error

    - by Hani
    Dears. I am using Matlab 2009b and having an out of memory error. I read other posted sol but they are not useful for me. I am sure that i am doing things right but i must use very huge amount of array sizes. I think that the problem lies beyond the fact that Matlab does not enable an array to be in more than one OS block. I am using Windows 7. Is there a way to get rid of this problem. For example can i increase the array block that Matlab uses in Windows 7? Thanks...Hani Almousli

  • How to use PHP to POST to a web page then get the results back, locally

    - by Patrick Gates
    I have a page on my web server that is PHP that is set to do this if ($_POST['post'] == true) { echo: 'hello, world'; } I want to create a page that calls to that page, posts "post" equal to "true" and then returns the value "hello, world". I have a script that works, but only if the pages are on different servers. Unfortunately, both of these pages are on the same server, so, heres my code, and I'm hoping you guys can help me, Thank you :) function post($site, $post) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$site); curl_setopt($ch, CURLOPT_FAILONERROR,1); curl_setopt ($ch, CURLOPT_POST, 1); curl_setopt ($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); curl_setopt($ch, CURLOPT_TIMEOUT, 15); $retValue = curl_exec($ch); curl_close($ch); return $retValue; } echo post('data.php', 'post=true');

  • Programatically determining file "size on disk" in advance

    - by porkchop
    I need to know how big a given in-memory buffer will be as an on-disk (usb stick) file before I write it. I know that unless the size falls on the block size boundary, its likely to get rounded up, e.g. a 1 byte file takes up 4096 bytes on-disk. I'm currently doing this using GetDiskFreeSpace() to work out the disk block size, then using this to calculate the on-disk size like this: GetDiskFreeSpace(szDrive, &dwSectorsPerCluster, &dwBytesPerSector, NULL, NULL); dwBlockSize = dwSectorsPerCuster * dwBytesPerSector; if (dwInMemorySize % dwBlockSize != 0) { dwSizeOnDisk = ((dwInMemorySize / dwBlockSize) * dwBlockSize) + dwBlockSize; } else { dwSizeOnDisk = dwInMemorySize; } Which seems to work fine, BUT GetDiskFreeSpace() only works on disks up to 2GB according to MSDN. GetDiskFreeSpaceEx() doesn't return the same information, so my question is, how else can I calculate this information for drives 2GB? Is there an API call I've missed? Can I assume some hard values depending on the overall disk size?

  • Using pthread condition variable with rwlock

    - by Doomsday
    Hello, I'm looking for a way to use pthread rwlock structure with conditions routines in C++. I have two questions: First: How is it possible and if we can't, why ? Second: Why current POSIX pthread have not implemented this behaviour ? To understand my purpose, I explain what will be my use: I've a producer-consumer model dealing with one shared array. The consumer will cond_wait when the array is empty, but rdlock when reading some elems. The producer will wrlock when adding(+signal) or removing elems from the array. The benefit of using rdlock instead of mutex_lock is to improve performance: when using mutex_lock, several readers would block, whereas using rdlock several readers would not block.

  • How can I ensure that JavaScript inserted via AJAX will be executed after the accompanying HTML (als

    - by RenderIn
    I've got portions of pages being replaced with HTML retrieved via AJAX calls. Some of the HTML coming back has JavaScript that needs to be run once in order to initialize the accompanying HTML (setting up event handlers). Since the document has already been loaded, when I replace chunks of HTML using jQuery's .html function, having jQuery(document).ready(function() {...}); doesn't execute since the page loaded long before and this is just a snippet of HTML being replaced. What's the best way to attach event handlers whose code is packaged along with the HTML it's interested in, when that content is loaded via AJAX? Should I just put a procedural block of javascript after the HTML , so that when I insert the new HTML block, jQuery will execute the javascript immediately? Is the HTML definitely in the DOM and ready to be acted upon by JavaScript which is in the same .html call?

  • Javascript : where are high level data structures?

    - by user355056
    Hi! I'm writing a client program for a game in Javascript but I'm new in Javascript world. Core Javascript lack of high level data structures. I've found code snippets on internet but I'm looking for a reference library (like commons-collection or google-collection in java world). I found this post: http://stackoverflow.com/questions/2523436/javascript-implementation-of-a-set-data-structure which refers to jshashtable and closure. Are they reference implementations? Do you know something else? Thanks

  • Inheriting from List<T> in .NET (vb or C#)

    - by Tony
    I have been delved in C++ world for a while, but now I'm in .NET world again, VB and C# and I wondered if you have a class that represents a collection of something, and you want the ability to use this in a foreach loop, etc... is it better to implement IEnumerable and IEnumerator yourself or should you inherit from the List<T> where T is the object type in it's singular form? I know in C++ for example, inheriting from a container is considered a bad idea. But what about .NET.

  • GCC fatal error: stdio.h: No such file or directory

    - by user2615799
    I'm trying to compile a program in C on OS X 10.9 with GCC 4.9 (experimental). For some reason, I'm getting the following error at compile time: gcc: fatal error: stdio.h: No such file or directory I then tried a simple Hello World program: #include <stdio.h> int main(int *argc, const char *argv[]) { printf("Hello, world!"); return 0; } Again, upon running gcc -o ~/hello ~/hello.c, I got the same error. I'm using an experimental version of gcc, but it seems implausible that there would be a release which generated errors upon importing stdio. What could be causing this issue, and how can it be fixed?

  • How to check whether iterators form a contiguous memory zone?

    - by Vincent
    I currently have the following function to read an array or a vector of raw data (_readStream is a std::ifstream) : template<typename IteratorType> inline bool MyClass::readRawData( const IteratorType& first, const IteratorType& last, typename std::iterator_traits<IteratorType>::iterator_category* = nullptr ) { _readStream.read(reinterpret_cast<char*>(&*first), (last-first)*sizeof(*first)); return _readStream.good(); } First question : does this function seem ok for you ? As we read directly a block of memory, it will only work if the memory block from first to last is contiguous in memory. How to check that ?

  • Internet Explorer doesn't update file

    - by Leandro
    Hi! I'm using AJAX with PHP to read from a file and update the div's innerHTML. It works on Chrome and Firefox, but not in Internet Explorer. I tried to use: But I think it is useless, since I'm not refreshing the page. if(!$newMsg || $newMsg == "") { // only reading from the file // do nothing } else { $fileData .= "$newMsg"; fwrite($fileHandler, "$newMsg"); } fclose($fileHandler); echo $fileData; Interesting that when it enters the "else" block, it shows the file's content updated. But when it enters the "if" block, it shows the old content.

  • JQuery remove image src prefix

    - by mtwallet
    Hi. I have a bunch of images on a page that are contained within a div with a class of content-block like this: <div class="content-block"> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> </div> I am loading this html into a div via ajax. When I load it in I need to remove the "../" before the image path, after it loads in so the path remains correct. Can this be done with JQuery? Many thanks in advance.

  • Are where any Visual Studio addings for true 'smart tabs'?

    - by Eye of Hell
    Hello. 'Smart Tabs' concept allows to automatically insert tab character for block indentation and space characters for in-block formatting. It's described here. Unfortunately, Visual Studio's 'smart tabs' option in text editor settings just indents text on enter press. Same name, completely different and near useless thing :). So, maybe someone knows of a visual studio addin that can change how 'tab' key work so it will insert tab characters and space characters according to rules mentioned above? Any hints are welcome.
