  • Intercepting mouse events using a global hook. Stop an action from happening.

    - by fMinkel
    I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part. I am using the (I assume pretty widely used) following code for Global Hooking of the mouse. Private Structure MSLLHOOKSTRUCT Public pt As Point Public mouseData As Int32 Public flags As Int32 Public time As Int32 Public extra As IntPtr End Structure Private _mouseHook As IntPtr Private Const WH_MOUSE_LL As Int32 = 14 Private Delegate Function MouseHookDelegate(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 <MarshalAs(UnmanagedType.FunctionPtr)> Private _mouseProc As MouseHookDelegate Private Declare Function SetWindowsHookExW Lib "user32.dll" (ByVal idHook As Int32, ByVal HookProc As MouseHookDelegate, ByVal hInstance As IntPtr, ByVal wParam As Int32) As IntPtr Private Declare Function UnhookWindowsHookEx Lib "user32.dll" (ByVal hook As IntPtr) As Boolean Private Declare Function CallNextHookEx Lib "user32.dll" (ByVal idHook As Int32, ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 Private Declare Function GetCurrentThreadId Lib "kernel32.dll" () As Integer Private Declare Function GetModuleHandleW Lib "kernel32.dll" (ByVal fakezero As IntPtr) As IntPtr Public Function HookMouse() As Boolean Debug.Print("Mouse Hooked") If _mouseHook = IntPtr.Zero Then _mouseProc = New MouseHookDelegate(AddressOf MouseHookProc) _mouseHook = SetWindowsHookExW(WH_MOUSE_LL, _mouseProc, GetModuleHandleW(IntPtr.Zero), 0) End If Return _mouseHook <> IntPtr.Zero End Function Public Sub UnHookMouse() Debug.Print("Mouse UnHooked") If _mouseHook = IntPtr.Zero Then Return UnhookWindowsHookEx(_mouseHook) _mouseHook = IntPtr.Zero End Sub Private Function MouseHookProc(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 'Debug.Print("Message = {0}, x={1}, y={2}", wParam.ToInt32, lParam.pt.X, lParam.pt.Y) If wParam.ToInt32 = 513 Then '''interrupt the left mouse button event here, but don't know what to return to do so.

  • Mediawiki authenication replacement showing "Login Required" instead of signing user into wiki

    - by arcdegree
    I'm fairly to MediaWiki and needed a way to automatically log users in after they authenticated to a central server (which creates a session and cookie for applications to use). I wrote a custom authentication extension based off of the LDAP Authentication extension and a few others. The extension simply needs to read some session data to create or update a user and then log them in automatically. All the authentication is handled externally. A user would not be able to even access the wiki website without logging in externally. This extension was placed into production which replaced the old standard MediaWiki authentication system. I also merged user accounts to prepare for the change. By default, a user must be logged in to view, edit, or otherwise do anything in the wiki. My problem is that I found if a user had previously used the built-in MediaWiki authentication system and returned to the wiki, my extension would attempt to auto-login the user, however, they would see a "Login Required" page instead of the page they requested like they were an anonymous user. If the user then refreshed the page, they would be able to navigate, edit, etc. From what I can tell, this issue resolves itself after the UserID cookie is reset or created fresh (but has been known to strangely come up sometimes). To replicate, if there is an older User ID in the "USERID" cookie, the user is shown the "Login Required" page which is a poor user experience. Another way of showing this page is by removing the user account from the database and refreshing the wiki page. As a result, the user will again see the "Login Required" page. Does anyone know how I can use debugging to find out why MediaWiki thinks the user is not signed in when the cookies are set properly and all it takes is a page refresh? Here is my extension (simplified a little for this post): <?php $wgExtensionCredits['parserhook'][] = array ( 'name' => 'MyExtension', 'author' => '', ); if (!class_exists('AuthPlugin')) { require_once ( 'AuthPlugin.php' ); } class MyExtensionPlugin extends AuthPlugin { function userExists($username) { return true; } function authenticate($username, $password) { $id = $_SESSION['id']; if($username = $id) { return true; } else { return false; } } function updateUser(& $user) { $name = $user->getName(); $user->load(); $user->mPassword = ''; $user->mNewpassword = ''; $user->mNewpassTime = null; $user->setRealName($_SESSION['name']); $user->setEmail($_SESSION['email']); $user->mEmailAuthenticated = wfTimestampNow(); $user->saveSettings(); return true; } function modifyUITemplate(& $template) { $template->set('useemail', false); $template->set('remember', false); $template->set('create', false); $template->set('domain', false); $template->set('usedomain', false); } function autoCreate() { return true; } function disallowPrefsEditByUser() { return array ( 'wpRealName' => true, 'wpUserEmail' => true, 'wpNick' => true ); } function allowPasswordChange() { return false; } function setPassword( $user, $password ) { return false; } function strict() { return true; } function initUser( & $user ) { } function updateExternalDB( $user ) { return false; } function canCreateAccounts() { return false; } function addUser( $user, $password ) { return false; } function getCanonicalName( $username ) { return $username; } } function SetupAuthMyExtension() { global $wgHooks; global $wgAuth; $wgHooks['UserLoadFromSession'][] = 'Auth_MyExtension_autologin_hook'; $wgHooks['UserLogoutComplete'][] = 'Auth_MyExtension_UserLogoutComplete'; $wgHooks['PersonalUrls'][] = 'Auth_MyExtension_personalURL_hook'; $wgAuth = new MyExtensionPlugin(); } function Auth_MyExtension_autologin_hook($user, &$return_user ) { global $wgUser; global $wgAuth; global $wgContLang; wfSetupSession(); // Give us a user, see if we're around $tmpuser = new User() ; $rc = $tmpuser->newFromSession(); $rc = $tmpuser->load(); if( $rc && $rc->isLoggedIn() ) { if ( $rc->authenticate($rc->getName(), '') ) { return true; } else { $rc->logout(); } } $id = trim($_SESSION['id']); $name = ucfirst(trim($_SESSION['name'])); if (empty($dsid)) { $result = false; // Deny access return true; } $user = User::newFromName($dsid); if (0 == $user->getID() ) { // we have a new user to add... $user->setName( $id); $user->addToDatabase(); $user->setToken(); $user->saveSettings(); $ssUpdate = new SiteStatsUpdate( 0, 0, 0, 0, 1 ); $ssUpdate->doUpdate(); } else { $user->saveToCache(); } // update email, real name, etc. $wgAuth->updateUser( $user ); $result = true; // Go ahead and log 'em in $user->setToken(); $user->saveSettings(); $user->setupSession(); $user->setCookies(); return true; } function Auth_MyExtension_personalURL_hook(& $personal_urls, & $title) { global $wgUser; unset( $personal_urls['mytalk'] ); unset($personal_urls['Userlogin']); $personal_urls['userpage']['text'] = $wgUser->getRealName(); foreach (array('login', 'anonlogin') as $k) { if (array_key_exists($k, $personal_urls)) { unset($personal_urls[$k]); } } return true; } function Auth_MyExtension_UserLogoutComplete(&$user, &$inject_html, $old_name) { setcookie( $GLOBALS['wgCookiePrefix'] .

  • How to pass a class method as an argument for another function in C++ and openGL?

    - by tsubasa
    I know this thing works: void myDisplay() { ... } int main() { ... glutDisplayFunc(myDisplay) ... } so I tried to include myDisplay() function to a class that I made. Because I want to overload it in the future with a different class. However, the compiler complains that argument of type 'void (ClassBlah::)()' does not match 'void(*)()' . Here is the what I try to make: class ClassBlah { .... void myDisplay() .... } ...... int main() { ... ClassBlah blah glutDisplayFunc(blah.myDisplay) ... } Does anybody knows how to fix this problem? Many thanks.

  • Can the lock function be used to implement thread-safe enumeration?

    - by Daniel
    I'm working on a thread-safe collection that uses Dictionary as a backing store. In C# you can do the following: private IEnumerable<KeyValuePair<K, V>> Enumerate() { if (_synchronize) { lock (_locker) { foreach (var entry in _dict) yield return entry; } } else { foreach (var entry in _dict) yield return entry; } } The only way I've found to do this in F# is using Monitor, e.g.: let enumerate() = if synchronize then seq { System.Threading.Monitor.Enter(locker) try for entry in dict -> entry finally System.Threading.Monitor.Exit(locker) } else seq { for entry in dict -> entry } Can this be done using the lock function? Or, is there a better way to do this in general? I don't think returning a copy of the collection for iteration will work because I need absolute synchronization.

  • Trying to simplify some Javascript with closures

    - by mvalente
    Hi, I'm trying to simplify some JS code that uses closures but I am getting nowhere (probably because I'm not grokking closures) I have some code that looks like this: var server = http.createServer(function (request, response) { var httpmethods = { "GET": function() { alert('GET') }, "PUT": function() { alert('PUT') } }; }); And I'm trying to simplify it in this way: var server = http.createServer(function (request, response) { var httpmethods = { "GET": function() { alertGET() }, "PUT": function() { alertPUT() } }; }); function alertGET() { alert('GET'); } function alertPUT() { alert('PUT'); } Unfortunately that doesnt seem to work... Thus: - what am I doing wrong? - is it possible to do this? - how? TIA -- MV

  • jQuery animation loop not working

    - by Marko Ivanovski
    Hi, I'm trying to create a looping animation that starts on onmousedown and stops on onmouseout. The effect is a simple scroll that will continue looping until you release the mouse. I've created a function which performs the .animate method and it passes itself as a callback but the code only runs once. Here's the entire code: $(document).ready(function() { var $scroller = $("#scroller"); var $content = $("#content", $scroller); // lineHeight equal to 1 line of text var lineHeight = $content.css('line-height'); //Amount to scroll = 3 lines of text a time var amountToScroll = lineHeight.replace("px","")*3; var maxScroll = $content.height() - $scroller.height(); function scrollDown() { var topCoord = $content.css("top").replace("px",""); if(topCoord > -maxScroll) { if((-maxScroll-topCoord) > -amountToScroll) { $content.stop().animate({ top: -maxScroll }, 1000 ); } else { $content.stop().animate({ top: "-=" + amountToScroll }, 1000, function(){ scrollDown() } ); } } } function scrollUp() { var topCoord = $content.css("top").replace("px",""); if(topCoord < 0) { if(topCoord > -amountToScroll) { $content.stop().animate({ top: 0 }, 1000 ); } else { $content.stop().animate({ top: "+=" + amountToScroll }, 1000, function(){scrollUp()} ); } } } $("#scroll-down").mousedown(function() { scrollDown(); }); $("#scroll-down").mouseup(function() { $content.stop(); }); $("#scroll-up").mousedown(function() { scrollUp(); }); $("scroll-up").mouseup(function() { $content.stop(); }); });

  • How to reduce the windows network browsing broadcast timeout or disable this function?

    - by Moi42
    Hello everyone. My residential network is make of 300 vlans (one per room). To browse them we are using a wins server. My problem is that when I try to browse the network, windows first tries to find the neighborhood using some broadcast, and only then does it query the wins server. This "broadcast period" lasts exactly 30 seconds and is very annoying. Can I reduce it, or can I completely disable this broadcast network discovery feature from my system? Thank you for your answers.

  • Possible for C++ template to check for a function's existence?

    - by andy
    Is it possible to write a C++ template that changes behavior depending on if a certain member function is defined on a class? Here's a simple example of what I would want to write: template<class T> std::string optionalToString(T* obj) { if (FUNCTION_EXISTS(T->toString)) return obj->toString(); else return "toString not defined"; } So if class T has "toString" defined then it uses it, otherwise it doesn't. The magical part that I don't know how to do is the "FUNCTION_EXISTS" part.

  • C++ - Where to code a member function for an inherited object.

    - by Francisco P.
    Hello! I have a few classes (heat, gas, contact, pressure) inheriting from a main one (sensor). I have a need to store them in a vector<Sensor *> (part of the specification). At some point in time, I need to call a function that indiscriminately stores those Sensor *. (also part of the specification, not open for discussion) Something like this: for(size_t i = 0; i < Sensors.size(); ++i) Sensors[i]->storeSensor(os) //os is an ofstream kind of object, passed onwards by reference Where and how shall storeSensor be defined? Is there any simple way to do this or will I need to disregard the specification? Mind you, I'm a beginner! Thanks for your time!

  • lua metatable __lt __le __eq forced boolean conversion of return value

    - by chris g.
    Overloading __eq, __lt, and __le in a metatable always converts the returning value to a boolean. Is there a way to access the actual return value? This would be used in the following little lua script to create an expression tree for an argument usage: print(_.a + _.b - _.c * _.d + _.a) -> prints "(((a+b)-(c*d))+a)" which is perfectly what I would like to have but it doesn't work for print(_.a == _.b) since the return value gets converted to a boolean ps: print should be replaced later with a function processing the expression tree -- snip from lua script -- function binop(op1,op2, event) if op1[event] then return op1[event](op1, op2) end if op2[event] then return op2[event](op1, op2) end return nil end function eq(op1, op2)return binop(op1,op2, "eq") end ... function div(op1, op2)return binop(op1,op2, "div") end function exprObj(tostr) expr = { eq = binExpr("=="), lt = binExpr("<"), le = binExpr("<="), add = binExpr("+"), sub=binExpr("-"), mul = binExpr("*"), div= binExpr("/") } setmetatable(expr, { __eq = eq, __lt = lt, __le = le, __add = add, __sub = sub, __mul = mul, __div = div, __tostring = tostr }) return expr end function binExpr(exprType) function binExprBind(lhs, rhs) return exprObj(function(op) return "(" .. tostring(lhs) .. exprType .. tostring(rhs) ..

  • Is there a .def file equicalent on Linux for controlling exported function names in a shared library

    - by morpheous
    I am building a shared library on Ubuntu 9.10. I want to export only a subset of my functions from the library. On the Windows platform, this would be done using a module definition ( .def) file which would contain a list of the external and internal names of the functions exported from the library. I have the following questions: How can I restrict the exported functions of a shared library to those I want (i.e. a .def file equivalent) Using .def files as an example, you can give a function an external name that is different from its internal name (useful for prevent name collisions and also redecorating mangled names etc) On windows I can use the EXPORT command (IIRC) to check the list of exported functions and addresses, what is the equivalent way to do this on Linux?

  • Add console.profile statements to JavaScript/jQuery code on the fly.

    - by novogeek
    Hi folks, We have a thick client app using jQuery heavily and want to profile the performance of the code using firebug's console.profile API. The problem is, I don't want to change the code to write the profile statements. Take this example: var search=function(){ this.init=function(){ console.log('init'); } this.ajax=function(){ console.log('ajax'); //make ajax call using $.ajax and do some DOM manipulations here.. } this.cache=function(){ console.log('cache'); } } var instance=new search(); instance.ajax(); I want to profile my instance.ajax method, but I dont want to add profile statements in the code, as that makes it difficult to maintain the code. I'm trying to override the methods using closures, like this: http://www.novogeek.com/post/2010/02/27/Overriding-jQueryJavaScript-functions-using-closures.aspx but am not very sure how I can achieve. Any pointers on this? I think this would help many big projects to profile the code easily without a big change in code. Here is the idea. Just run the below code in firebug console, to know what I'm trying to achieve. var search=function(){ this.init=function(){ console.log('init'); } this.ajax=function(){ console.log('ajax'); //make ajax call using $.ajax and do some DOM manipulations here.. } this.cache=function(){ console.log('cache'); } } var instance=new search(); $.each(instance, function(functionName, functionBody){ (function(){ var dup=functionBody functionBody=function(){ console.log('modifying the old function: ',functionName); console.profile(functionName); dup.apply(this,arguments); console.profileEnd(functionName); } })(); console.log(functionName, '::', functionBody()); }); Now what I need is, if i say instance.ajax(), I want the new ajax() method to be called, along with the console.profile statements. Hope I'm clear with the requirement. Please improvise the above code. Regards, Krishna, http://www.novogeek.com

  • Can a function defined in a bookmarklet be called from a page-level script?

    - by Soviut
    I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

  • Problem accessing private variables in jQuery like chainable design pattern

    - by novogeek
    Hi folks, I'm trying to create my custom toolbox which imitates jQuery's design pattern. Basically, the idea is somewhat derived from this post: http://stackoverflow.com/questions/2061501/jquery-plugin-design-pattern-common-practice-for-dealing-with-private-function (Check the answer given by "David"). So here is my toolbox function: (function(window){ var mySpace=function(){ return new PrivateSpace(); } var PrivateSpace=function(){ var testCache={}; }; PrivateSpace.prototype={ init:function(){ console.log('init this:', this); return this; }, ajax:function(){ console.log('make ajax calls here'); return this; }, cache:function(key,selector){ console.log('cache selectors here'); testCache[key]=selector; console.log('cached selector: ',testCache); return this; } } window.hmis=window.m$=mySpace(); })(window) Now, if I execute this function like: console.log(m$.cache('firstname','#FirstNameTextbox')); I get an error 'testCache' is not defined. I'm not able to access the variable "testCache" inside my cache function of the prototype. How should I access it? Basically, what I want to do is, I want to cache all my jQuery selectors into an object and use this object in the future.

I'm using Jquery to do this, but the shared imgIndex seems to be off from the .keydown function and the .click function... Whenever .keydown function -- or ++ the imgIndex, isn't that changed index also used in the click function? So shouldn't they always be on the same index? keydown function: <script type="text/javascript"> var imgArray = [<?php echo implode(',', getImages($site)) ?>]; $(document).ready(function() { var img = document.getElementById("showimg"); img.src = imgArray[<?php echo $imgid ?>]; var imgIndex = <?php echo $imgid ?>; alert(imgIndex); $(document).keydown(function (e) { var key = e.which; var rightarrow = 39; var leftarrow = 37; var random = 82; if (key == rightarrow) { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; } if (key == leftarrow) { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; } }); click function: Connected to left and right clickable images $("#next").click(function() { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; }); $("#prev").click(function() { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; }); }); Just so you have some visibility into the getImages php function: <?php function getImages($siteParam) { include 'dbconnect.php'; if ($siteParam == 'artwork') { $table = "artwork"; } else { $table = "comics"; } $catResult = $mysqli->query("SELECT id, title, path, thumb, views, catidFK FROM $table"); $img = array(); while($row = $catResult->fetch_assoc()) { $img[] = "'" . $row['path'] . "'"; } return $img; } ?> Much appreciated! Snapshot of where the script is on "view image.php"

  • Is there a good (standalone) PHPDoc parser class or function in PHP?

    - by Kris
    Hi folks, I'm looking for some method of converting a PHP Docblock (as used for generating documentation by tools like Doxygen) into a structure I can inspect in PHP. For example, I want to parse the following lines: /** * Multiply two values * @CHECKME * * @author someone * @created eons ago * * @param integer $x * @param integer $x * * @return integer */ function multiply($x, $y) { return $x * $y; } Into something similar to: array( 'author' = 'someone' ,'created' = 'eons ago' ,'param' = array( 'integer $x' ,'integer $y' ) ,'_flags' = array( '@CHECKME' ) ); I explicitly cannot use PEAR or any such library, it has to be relatively standalone. Any given solution that is better than using a bunch of regexes after stripping away comment outline would be awesome.
