  • Executing Multiple Lines in Python

    - by metashockwave
    When Python is first installed, the default setting executes users' code input line-by-line. But sometimes I need to write programs that executes multiple lines at once. Is there a setting in Python where I can change the code execution to one block at once? Thanks if (n/2) * 2 == n:; print 'Even'; else: print 'Odd' SyntaxError: invalid syntax When I tried to run the above code, I got an invalid syntax error on ELSE

  • Library to parse C/C++ source code

    - by John
    Which library should I use to parse C/C++ source code file? I need to parse source file, calculate how much useful strings inside, how much 'for' blocks, 'if' blocks, how much comments inside. I also may need to insert a comment or small piece of code after each 'for' block. Is there any libraries? May be any library included in Microsoft Visual Studio?

  • C instruction address

    - by aaa
    hello. Disclaimer, I not do anything in particular with regards this question, just curious. Is it possible to take address of instruction or block in C? in essence, is there jump equivalent in C? for example: void function() { int k; { // is a possible to go to this address from arbitrary point in code? int i, j; k += j+i; } } thank you

  • JPanels, JFrames, and Windows, Oh my!

    - by Jonathan
    Simply stated, I am trying to make a game I am working on full-screen. I have the following code I am trying to use: GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice gs = ge.getDefaultScreenDevice(); if(!gs.isFullScreenSupported()) { System.out.println("full-screen not supported"); } Frame frame = new Frame(gs.getDefaultConfiguration()); Window win = new Window(frame); try { // Enter full-screen mode gs.setFullScreenWindow(win); win.validate(); } Problem with this is that I am working within a class that extends JPanel, and while I have a variable of type Frame, I have none of type Window within the class. My understanding of JPanel is that it is a Window of sorts, but I cannot pass 'this' into gs.setFullScreenWindow(Window win)... How should I go about doing this? Is there any easy way of calling that, or a similar method, using a JPanel? Is there a way I can get something of type Window from my JPanel? - EDIT: The following method changes the state of JFrame and is called every 10ms: public void paintScreen() { Graphics g; try{ g = this.getGraphics(); //get Panel's graphic context if(g == null) { frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setExtendedState(frame.getExtendedState()|JFrame.MAXIMIZED_BOTH); frame.add(this); frame.pack(); frame.setResizable(false); frame.setTitle("Game Window"); frame.setVisible(true); } if((g != null) && (dbImage != null)) { g.drawImage(dbImage, 0, 0, null); } Toolkit.getDefaultToolkit().sync(); //sync the display on some systems g.dispose(); } catch (Exception e) { if(blockError) { blockError = false; } else { System.out.println("Graphics context error: " + e); } } } I anticipate that there may be a few redundancies or unnecessary calls after the if(g==null) statement (all the frame.somethingOrOther()s), any cleanup advice would be appreciated... Also, the block error is what it seems. I am ignoring an error. The error only occurs once, and this works fine when setup to ignore the first instance of the error... For anyone interested I can post additional info there if anyone wants to see if that block can be removed, but i'm not concerned... I might look into it later.

  • Plugin for R# similar to CodeRush "statement highlight"

    - by KiwiBastard
    See here http://www.hanselman.com/blog/InSearchOfThePerfectMonospacedProgrammersFontInconsolata.aspx - for want of a better description - the statement block highlighting - eg in the pics on the link the "statement blocks" are grouped with a vertical line. I understand this is a feature of CodeRush - does R# have either anything similar, or a plugin to do the same?

  • ASP.NET Master Page + pageLoad() = kills jquery?

    - by Clay Angelly
    In my MasterPage, I have a ScriptManager that has a ScriptReference to my jquery.js file. This has always worked with no problems, all content pages that utilize jquery work fine. Recently, I added the following javascript script block at the end of my MasterPage: function pageLoad(sender, args) { } By simply adding the above pageLoad method, no jquery code is executed from any of my content pages. Why would just having a pageLoad in the Master Page have this effect? Thanks in advance for any insight.

  • Linking to a section of a site that is hidden by a hide/show JavaScript function

    - by hollyb
    I am using a bit of JavaScript to show/hide sections of a site when a tab is clicked. I'm trying to figure out if there is a way I can link back to the page and have a certain tab open based on that link. Here is the JS: var ids=new Array('section1','section2','section3','section4'); function switchid(id, el){ hideallids(); showdiv(id); var li = el.parentNode.parentNode.childNodes[0]; while (li) { if (!li.tagName || li.tagName.toLowerCase() != "li") li = li.nextSibling; // skip the text node if (li) { li.className = ""; li = li.nextSibling; } } el.parentNode.className = "active"; } function hideallids(){ //loop through the array and hide each element by id for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id document.getElementById(id).style.display = 'none'; } function showdiv(id) { //safe function to show an element with a specified id document.getElementById(id).style.display = 'block'; } And the HTML <ul> <li class="active"><a onclick="switchid('section1', this);return false;">One</a></li> <li><a onclick="switchid('section2', this);return false;">Two</a></li> <li><a onclick="switchid('section3', this);return false;">Three</a></li> <li><a onclick="switchid('section4', this);return false;">Four</a></li> </ul> <div id="section1" style="display:block;"> <div id="section2" style="display:none;"> <div id="section3" style="display:none;"> <div id="section4" style="display:none;"> I haven't been able to come up with a way to link back to a specific section. Is it even possible with this method? Thanks!

  • Overlapping and Stacking in CSS

    - by ApacheCode
    Hello, I'm a programmer and learning new techniques in web development. I've ran into a problem if you could look at the link below. http://bailesslaw.com/Bailess_003/bailesHeader/header.html This example I made isnt fixed and it needs to be, which is becoming difficult. This looks fine on here, but when I put those layers on main website, index.html, place this code as the header, the banner moves in the documents position 0,0 . I need these boxes fixed, center page and I cannot get them to do that without messing up the layers order and content. Layer1-rotating images, js causes the rotation Layer2-blue triangle with backdrop effect overlapping layer 1, Layer 3-is a static image with a high z-index Below I including some code, the important part that needs 3 overlapped layers exactly matching in width and height, except it has to be fixed in center 780px wide. Code: <style rel="stylesheet" type="text/css"> div#layer1 { border: 1px solid #000; height: 200px; left: 0px; position: fixed; top: 0px; width: 780px; z-index: 1; } div#layer2 { border: 1px solid #000; height: 200px; left: 0px; position: absolute; top: 0px; width: 780px; z-index: 2; } div#layer3 { border: 1px solid #000000; height: 200px; left: 0px; position: absolute; top: 0px; width: 780px; z-index: 3; } </style> </head> <body class="oneColFixCtr"> <div id="container"> <div id="mainContent"> <div id="layer1"> </div> <div id="layer2"> <div class="slideshow"> <span id="rotating1"> <p class="rotating"> </p> </span> <span id="rotating2"> <p class="rotating"> </p> </span> <span id="rotating3"> <p class="rotating"> </p> </span> <span id="rotating4"> <p class="rotating"> </p> </span> </div> </div> <div id="layer3"> <table width="385" border="0"> <tr> <th width="81" scope="col"> &nbsp; </th> <th width="278" scope="col"> &nbsp; </th> <th width="12" scope="col"> &nbsp; </th> </tr> <tr> <td> &nbsp; </td> <td> </td> <td> &nbsp; </td> </tr> <tr> <td> &nbsp; </td> <td> &nbsp; </td> <td> &nbsp; </td> </tr> </table> </div> </div> <!-- end #container --> </div> </body> </body> </html> CSS: @charset "utf-8"; CSS code: #rotating1 { height: 200px; width: 780px; } #rotating2 { height: 200px; width: 780px; } #rotating3 { height: 200px; width: 780px; } #main { background-repeat: no-repeat; height: 200px; width: 780px; z-index: 100; } #test { width: 780px; z-index: 2; } #indexContent { background-color: #12204d; background-repeat: no-repeat; height: 200px; width: 780px; z-index: 1; } #indexContent p { padding: .5em 2em .5em 2em; text-align: justify; text-indent: 2em; } .rotating { float: right; margin-top: 227px; text-indent: 0px !important; } .clearfix:after { clear: both; content: " "; display: block; font-size: 0; height: 0; visibility: hidden; } .clearfix { display: inline-block; } * html .clearfix { height: 1%; } .clearfix { display: block; }

  • Make a final call to the Database when user leaves website (ASPX)?

    - by Jisaak
    I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?

  • Access.Application.CurrentDb is Nothing?

    - by Allain Lalonde
    I'm at a loss to explain this one: I'm getting an error "91" (Object or With block not set) on the second line below: Dim rs As DAO.Recordset Set rs = CurrentDb.OpenRecordset("SELECT * FROM employees") The following also causes it: Set rs = CurrentDb.OpenRecordset("employees") Executing ?CurrentDb.Name alone in the immediate window causes the error as well. Now, clearly the database is open since I'm editing the form within it, so what can cause this error here?
