  • Linux: How do I use Munin in cPanel to monitor MySQL?

    - by Continuation
    I have a cPanel server running CentOS 5.5. I want to use Munin to monitor MySQL. I went to: Main >> cPanel >> Manage Plugins and selected "Install and keep updated" for Munin and clicked "Save". I got the usual bunch of status updates about the install. At the end I got: Going to read '/home/.cpan/sources/modules/02packages.details.txt.gz' Database was generated on Wed, 02 Mar 2011 18:28:33 GMT ..........................................................................DONE Going to read '/home/.cpan/sources/modules/03modlist.data.gz' Out of memory! Callback called exit. Done Done Done Process Complete As you can see I got an "Out of memory!" message. But after that it said "Process Complete". Was Munin installed? When I went back to "Manage Plugins" it Munin has a check that against "Install and keep updated". So is everything alright? And how do I use Munin now? How do i configure it to monitor MySQL? Where can I see the results? Thanks.

  • Avoid richfaces to send back javascript libraries in the ajax responses

    - by pakore
    I'm using JSF 1.2 with Richfaces, and for every ajax request, the server is sending back the response, whichi is good, but it also contains all the links to the javascript files. I want to improve the performance so I just want the <body> to be returned, because all the javascript files are already loaded in the browser when the user logs in (my app is not restful). How can i do that? Thanks This is an example of a response to reRender an image when clicking a button. <?xml version="1.0"?> <html lang="nl_NL" xmlns="http://www.w3.org/1999/xhtml"><head><title></title><link

  • InternalsVisibleTo attribute and security vulnerability

    - by Sergey Litvinov
    I found one issue with InternalsVisibleTo attribute usage. The idea of InternalsVisibleTo attribute to allow some other assemblies to use internal classes\methods of this assembly. To make it work you need sign your assemblies. So, if other assemblies isn't specified in main assembly and if they have incorrect public key, then they can't use Internal members. But the issue in Reflection Emit type generation. For example, we have CorpLibrary1 assembly and it has such class: public class TestApi { internal virtual void DoSomething() { Console.WriteLine("Base DoSomething"); } public void DoApiTest() { // some internal logic // ... // call internal method DoSomething(); } } This assembly is marked with such attribute to allow another CorpLibrary2 to make inheritor for that TestAPI and override behaviour of DoSomething method. [assembly: InternalsVisibleTo("CorpLibrary2, PublicKey=0024000004800000940000000602000000240000525341310004000001000100434D9C5E1F9055BF7970B0C106AAA447271ECE0F8FC56F6AF3A906353F0B848A8346DC13C42A6530B4ED2E6CB8A1E56278E664E61C0D633A6F58643A7B8448CB0B15E31218FB8FE17F63906D3BF7E20B9D1A9F7B1C8CD11877C0AF079D454C21F24D5A85A8765395E5CC5252F0BE85CFEB65896EC69FCC75201E09795AAA07D0")] The issue is that I'm able to override this internal DoSomething method and break class logic. My steps to do it: Generate new assembly in runtime via AssemblyBuilder Get AssemblyName from CorpLibrary1 and copy PublikKey to new assembly Generate new assembly that will inherit TestApi class As PublicKey and name of generated assembly is the same as in InternalsVisibleTo, then we can generate new DoSomething method that will override internal method in TestAPI assembly Then we have another assembly that isn't related to this CorpLibrary1 and can't use internal members. We have such test code in it: class Program { static void Main(string[] args) { var builder = new FakeBuilder(InjectBadCode, "DoSomething", true); TestApi fakeType = builder.CreateFake(); fakeType.DoApiTest(); // it will display: // Inject bad code // Base DoSomething Console.ReadLine(); } public static void InjectBadCode() { Console.WriteLine("Inject bad code"); } } And this FakeBuilder class has such code: /// /// Builder that will generate inheritor for specified assembly and will overload specified internal virtual method /// /// Target type public class FakeBuilder { private readonly Action _callback; private readonly Type _targetType; private readonly string _targetMethodName; private readonly string _slotName; private readonly bool _callBaseMethod; public FakeBuilder(Action callback, string targetMethodName, bool callBaseMethod) { int randomId = new Random((int)DateTime.Now.Ticks).Next(); _slotName = string.Format("FakeSlot_{0}", randomId); _callback = callback; _targetType = typeof(TFakeType); _targetMethodName = targetMethodName; _callBaseMethod = callBaseMethod; } public TFakeType CreateFake() { // as CorpLibrary1 can't use code from unreferences assemblies, we need to store this Action somewhere. // And Thread is not bad place for that. It's not the best place as it won't work in multithread application, but it's just a sample LocalDataStoreSlot slot = Thread.AllocateNamedDataSlot(_slotName); Thread.SetData(slot, _callback); // then we generate new assembly with the same nameand public key as target assembly trusts by InternalsVisibleTo attribute var newTypeName = _targetType.Name + "Fake"; var targetAssembly = Assembly.GetAssembly(_targetType); AssemblyName an = new AssemblyName(); an.Name = GetFakeAssemblyName(targetAssembly); // copying public key to new generated assembly var assemblyName = targetAssembly.GetName(); an.SetPublicKey(assemblyName.GetPublicKey()); an.SetPublicKeyToken(assemblyName.GetPublicKeyToken()); AssemblyBuilder assemblyBuilder = Thread.GetDomain().DefineDynamicAssembly(an, AssemblyBuilderAccess.RunAndSave); ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule(assemblyBuilder.GetName().Name, true); // create inheritor for specified type TypeBuilder typeBuilder = moduleBuilder.DefineType(newTypeName, TypeAttributes.Public | TypeAttributes.Class, _targetType); // LambdaExpression.CompileToMethod can be used only with static methods, so we need to create another method that will call our Inject method // we can do the same via ILGenerator, but expression trees are more easy to use MethodInfo methodInfo = CreateMethodInfo(moduleBuilder); MethodBuilder methodBuilder = typeBuilder.DefineMethod(_targetMethodName, MethodAttributes.Public | MethodAttributes.Virtual); ILGenerator ilGenerator = methodBuilder.GetILGenerator(); // call our static method that will call inject method ilGenerator.EmitCall(OpCodes.Call, methodInfo, null); // in case if we need, then we put call to base method if (_callBaseMethod) { var baseMethodInfo = _targetType.GetMethod(_targetMethodName, BindingFlags.NonPublic | BindingFlags.Instance); // place this to stack ilGenerator.Emit(OpCodes.Ldarg_0); // call the base method ilGenerator.EmitCall(OpCodes.Call, baseMethodInfo, new Type[0]); // return ilGenerator.Emit(OpCodes.Ret); } // generate type, create it and return to caller Type cheatType = typeBuilder.CreateType(); object type = Activator.CreateInstance(cheatType); return (TFakeType)type; } /// /// Get name of assembly from InternalsVisibleTo AssemblyName /// private static string GetFakeAssemblyName(Assembly assembly) { var internalsVisibleAttr = assembly.GetCustomAttributes(typeof(InternalsVisibleToAttribute), true).FirstOrDefault() as InternalsVisibleToAttribute; if (internalsVisibleAttr == null) { throw new InvalidOperationException("Assembly hasn't InternalVisibleTo attribute"); } var ind = internalsVisibleAttr.AssemblyName.IndexOf(","); var name = internalsVisibleAttr.AssemblyName.Substring(0, ind); return name; } /// /// Generate such code: /// ((Action)Thread.GetData(Thread.GetNamedDataSlot(_slotName))).Invoke(); /// private LambdaExpression MakeStaticExpressionMethod() { var allocateMethod = typeof(Thread).GetMethod("GetNamedDataSlot", BindingFlags.Static | BindingFlags.Public); var getDataMethod = typeof(Thread).GetMethod("GetData", BindingFlags.Static | BindingFlags.Public); var call = Expression.Call(allocateMethod, Expression.Constant(_slotName)); var getCall = Expression.Call(getDataMethod, call); var convCall = Expression.Convert(getCall, typeof(Action)); var invokExpr = Expression.Invoke(convCall); var lambda = Expression.Lambda(invokExpr); return lambda; } /// /// Generate static class with one static function that will execute Action from Thread NamedDataSlot /// private MethodInfo CreateMethodInfo(ModuleBuilder moduleBuilder) { var methodName = "_StaticTestMethod_" + _slotName; var className = "_StaticClass_" + _slotName; TypeBuilder typeBuilder = moduleBuilder.DefineType(className, TypeAttributes.Public | TypeAttributes.Class); MethodBuilder methodBuilder = typeBuilder.DefineMethod(methodName, MethodAttributes.Static | MethodAttributes.Public); LambdaExpression expression = MakeStaticExpressionMethod(); expression.CompileToMethod(methodBuilder); var type = typeBuilder.CreateType(); return type.GetMethod(methodName, BindingFlags.Static | BindingFlags.Public); } } remarks about sample: as we need to execute code from another assembly, CorpLibrary1 hasn't access to it, so we need to store this delegate somewhere. Just for testing I stored it in Thread NamedDataSlot. It won't work in multithreaded applications, but it's just a sample. I know that we use Reflection to get private\internal members of any class, but within reflection we can't override them. But this issue is allows anyone to override internal class\method if that assembly has InternalsVisibleTo attribute. I tested it on .Net 3.5\4 and it works for both of them. How does it possible to just copy PublicKey without private key and use it in runtime? The whole sample can be found there - https://github.com/sergey-litvinov/Tests_InternalsVisibleTo UPDATE1: That test code in Program and FakeBuilder classes hasn't access to key.sn file and that library isn't signed, so it hasn't public key at all. It just copying it from CorpLibrary1 by using Reflection.Emit

  • Understanding and Implementing a Force based graph layout algorithm

    - by zcourts
    I'm trying to implement a force base graph layout algorithm, based on http://en.wikipedia.org/wiki/Force-based_algorithms_(graph_drawing) My first attempt didn't work so I looked at http://blog.ivank.net/force-based-graph-drawing-in-javascript.html and https://github.com/dhotson/springy I changed my implementation based on what I thought I understood from those two but I haven't managed to get it right and I'm hoping someone can help? JavaScript isn't my strong point so be gentle... If you're wondering why write my own. In reality I have no real reason to write my own I'm just trying to understand how the algorithm is implemented. Especially in my first link, that demo is brilliant. This is what I've come up with //support function.bind - https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind#Compatibility if (!Function.prototype.bind) { Function.prototype.bind = function (oThis) { if (typeof this !== "function") { // closest thing possible to the ECMAScript 5 internal IsCallable function throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable"); } var aArgs = Array.prototype.slice.call(arguments, 1), fToBind = this, fNOP = function () {}, fBound = function () { return fToBind.apply(this instanceof fNOP ? this : oThis || window, aArgs.concat(Array.prototype.slice.call(arguments))); }; fNOP.prototype = this.prototype; fBound.prototype = new fNOP(); return fBound; }; } (function() { var lastTime = 0; var vendors = ['ms', 'moz', 'webkit', 'o']; for(var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) { window.requestAnimationFrame = window[vendors[x]+'RequestAnimationFrame']; window.cancelAnimationFrame = window[vendors[x]+'CancelAnimationFrame'] || window[vendors[x]+'CancelRequestAnimationFrame']; } if (!window.requestAnimationFrame) window.requestAnimationFrame = function(callback, element) { var currTime = new Date().getTime(); var timeToCall = Math.max(0, 16 - (currTime - lastTime)); var id = window.setTimeout(function() { callback(currTime + timeToCall); }, timeToCall); lastTime = currTime + timeToCall; return id; }; if (!window.cancelAnimationFrame) window.cancelAnimationFrame = function(id) { clearTimeout(id); }; }()); function Graph(o){ this.options=o; this.vertices={}; this.edges={};//form {vertexID:{edgeID:edge}} } /** *Adds an edge to the graph.

  • iphone: Help with AudioToolbox Leak: Stack trace/code included here...

    - by editor guy
    Part of this app is a "Scream" button that plays random screams from cast members of a TV show. I have to bang on the app quite a while to see a memory leak in Instruments, but it's there, occasionally coming up (every 45 seconds to 2 minutes.) The leak is 3.50kb when it occurs. Haven't been able to crack it for several hours. Any help appreciated. Instruments says this is the offending code line: [appSoundPlayer play]; that's linked to from line 9 of the below stack trace: 0 libSystem.B.dylib malloc 1 libSystem.B.dylib pthread_create 2 AudioToolbox CAPThread::Start() 3 AudioToolbox GenericRunLoopThread::Start() 4 AudioToolbox AudioQueueNew(bool, AudioStreamBasicDescription const*, TCACallback const&, CACallbackTarget const&, unsigned long, OpaqueAudioQueue*) 5 AudioToolbox AudioQueueNewOutput 6 AVFoundation allocAudioQueue(AVAudioPlayer, AudioPlayerImpl*) 7 AVFoundation prepareToPlayQueue(AVAudioPlayer*, AudioPlayerImpl*) 8 AVFoundation -[AVAudioPlayer prepareToPlay] 9 Scream Queens -[ScreamViewController scream:] /Users/laptop2/Desktop/ScreamQueens Versions/ScreamQueens25/Scream Queens/Classes/../ScreamViewController.m:210 10 CoreFoundation -[NSObject performSelector:withObject:withObject:] 11 UIKit -[UIApplication sendAction:to:from:forEvent:] 12 UIKit -[UIApplication sendAction:toTarget:fromSender:forEvent:] 13 UIKit -[UIControl sendAction:to:forEvent:] 14 UIKit -[UIControl(Internal) _sendActionsForEvents:withEvent:] 15 UIKit -[UIControl touchesEnded:withEvent:] 16 UIKit -[UIWindow _sendTouchesForEvent:] 17 UIKit -[UIWindow sendEvent:] 18 UIKit -[UIApplication sendEvent:] 19 UIKit _UIApplicationHandleEvent 20 GraphicsServices PurpleEventCallback 21 CoreFoundation CFRunLoopRunSpecific 22 CoreFoundation CFRunLoopRunInMode 23 GraphicsServices GSEventRunModal 24 UIKit -[UIApplication _run] 25 UIKit UIApplicationMain 26 Scream Queens main /Users/laptop2/Desktop/ScreamQueens Versions/ScreamQueens25/Scream Queens/main.m:14 27 Scream Queens start Here's .h: #import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> #import <MediaPlayer/MediaPlayer.h> #import <AudioToolbox/AudioToolbox.h> #import <MessageUI/MessageUI.h> #import <MessageUI/MFMailComposeViewController.h> @interface ScreamViewController : UIViewController <UIApplicationDelegate, AVAudioPlayerDelegate, MFMailComposeViewControllerDelegate> { //AudioPlayer related AVAudioPlayer *appSoundPlayer;

  • Marshalling to a native library in C#

    - by Daniel Baulig
    I'm having trouble calling functions of a native library from within managed C# code. I am developing for the 3.5 compact framework (Windows Mobile 6.x) just in case this would make any difference. I am working with the waveIn* functions from coredll.dll (these are in winmm.dll in regular Windows I believe). This is what I came up with: // namespace winmm; class winmm [StructLayout(LayoutKind.Sequential)] public struct WAVEFORMAT { public ushort wFormatTag; public ushort nChannels; public uint nSamplesPerSec; public uint nAvgBytesPerSec; public ushort nBlockAlign; public ushort wBitsPerSample; public ushort cbSize; } [StructLayout(LayoutKind.Sequential)] public struct WAVEHDR { public IntPtr lpData; public uint dwBufferLength; public uint dwBytesRecorded; public IntPtr dwUser; public uint dwFlags; public uint dwLoops; public IntPtr lpNext; public IntPtr reserved; } public delegate void AudioRecordingDelegate(IntPtr deviceHandle, uint message, IntPtr instance, ref WAVEHDR wavehdr, IntPtr reserved2); [DllImport("coredll.dll")] public static extern int waveInAddBuffer(IntPtr hWaveIn, ref WAVEHDR lpWaveHdr, uint cWaveHdrSize); [DllImport("coredll.dll")] public static extern int waveInPrepareHeader(IntPtr hWaveIn, ref WAVEHDR lpWaveHdr, uint Size); [DllImport("coredll.dll")] public static extern int waveInStart(IntPtr hWaveIn); // some other class private WinMM.WinMM.AudioRecordingDelegate waveIn; private IntPtr handle; private uint bufferLength; private void setupBuffer() { byte[] buffer = new byte[bufferLength]; GCHandle bufferPin = GCHandle.Alloc(buffer, GCHandleType.Pinned); WinMM.WinMM.WAVEHDR hdr = new WinMM.WinMM.WAVEHDR(); hdr.lpData = bufferPin.AddrOfPinnedObject(); hdr.dwBufferLength = this.bufferLength; hdr.dwFlags = 0; int i = WinMM.WinMM.waveInPrepareHeader(this.handle, ref hdr, Convert.ToUInt32(Marshal.SizeOf(hdr))); if (i != WinMM.WinMM.MMSYSERR_NOERROR) { this.Text = "Error: waveInPrepare"; return; } i = WinMM.WinMM.waveInAddBuffer(this.handle, ref hdr, Convert.ToUInt32(Marshal.SizeOf(hdr))); if (i != WinMM.WinMM.MMSYSERR_NOERROR) { this.Text = "Error: waveInAddrBuffer"; return; } } private void setupWaveIn() { WinMM.WinMM.WAVEFORMAT format = new WinMM.WinMM.WAVEFORMAT(); format.wFormatTag = WinMM.WinMM.WAVE_FORMAT_PCM; format.nChannels = 1; format.nSamplesPerSec = 8000; format.wBitsPerSample = 8; format.nBlockAlign = Convert.ToUInt16(format.nChannels * format.wBitsPerSample); format.nAvgBytesPerSec = format.nSamplesPerSec * format.nBlockAlign; this.bufferLength = format.nAvgBytesPerSec; format.cbSize = 0; int i = WinMM.WinMM.waveInOpen(out this.handle, WinMM.WinMM.WAVE_MAPPER, ref format, Marshal.GetFunctionPointerForDelegate(waveIn), 0, WinMM.WinMM.CALLBACK_FUNCTION); if (i != WinMM.WinMM.MMSYSERR_NOERROR) { this.Text = "Error: waveInOpen"; return; } setupBuffer(); WinMM.WinMM.waveInStart(this.handle); } I read alot about marshalling the last few days, nevertheless I do not get this code working. When my callback function is called (waveIn) when the buffer is full, the hdr structure passed back in wavehdr is obviously corrupted. Here is an examlpe of how the structure looks like at that point: - wavehdr {WinMM.WinMM.WAVEHDR} WinMM.WinMM.WAVEHDR dwBufferLength 0x19904c00 uint dwBytesRecorded 0x0000fa00 uint dwFlags 0x00000003 uint dwLoops 0x1990f6a4 uint + dwUser 0x00000000 System.IntPtr + lpData 0x00000000 System.IntPtr + lpNext 0x00000000 System.IntPtr + reserved 0x7c07c9a0 System.IntPtr This obiously is not what I expected to get passed. I am clearly concerned about the order of the fields in the view. I do not know if Visual Studio .NET cares about actual memory order when displaying the record in the "local"-view, but they are obviously not displayed in the order I speciefied in the struct. Then theres no data pointer and the bufferLength field is far to high. Interestingly the bytesRecorded field is exactly 64000 - bufferLength and bytesRecorded I'd expect both to be 64000 though. I do not know what exactly is going wrong, maybe someone can help me out on this. I'm an absolute noob to managed code programming and marshalling so please don't be too harsh to me for all the stupid things I've propably done. Oh here's the C code definition for WAVEHDR which I found here, I believe I might have done something wrong in the C# struct definition: /* wave data block header */ typedef struct wavehdr_tag { LPSTR lpData; /* pointer to locked data buffer */ DWORD dwBufferLength; /* length of data buffer */ DWORD dwBytesRecorded; /* used for input only */ DWORD_PTR dwUser; /* for client's use */ DWORD dwFlags; /* assorted flags (see defines) */ DWORD dwLoops; /* loop control counter */ struct wavehdr_tag FAR *lpNext; /* reserved for driver */ DWORD_PTR reserved; /* reserved for driver */ } WAVEHDR, *PWAVEHDR, NEAR *NPWAVEHDR, FAR *LPWAVEHDR; If you are used to work with all those low level tools like pointer-arithmetic, casts, etc starting writing managed code is a pain in the ass. It's like trying to learn how to swim with your hands tied on your back. Some things I tried (to no effect): .NET compact framework does not seem to support the Pack = 2^x directive in [StructLayout]. I tried [StructLayout(LayoutKind.Explicit)] and used 4 bytes and 8 bytes alignment. 4 bytes alignmentgave me the same result as the above code and 8 bytes alignment only made things worse - but that's what I expected. Interestingly if I move the code from setupBuffer into the setupWaveIn and do not declare the GCHandle in the context of the class but in a local context of setupWaveIn the struct returned by the callback function does not seem to be corrupted. I am not sure however why this is the case and how I can use this knowledge to fix my code. I'd really appreciate any good links on marshalling, calling unmanaged code from C#, etc. Then I'd be very happy if someone could point out my mistakes. What am I doing wrong? Why do I not get what I'd expect.

  • javascript to reference input IDs in php loop and pass values back to same input ID

    - by Smudger
    I have a form which is essentially an autocomplete input box. I can get this to work perfectly for a single text box. What I need to do is create unique input boxes by using a php for loop. This will use the counter $i to give each input box a unique name and id. The problem is that the unique value of the input box needs to be passed to the javascript. this will then pass the inputted data to the external php page and return the mysql results. As mentioned I have this working for a single input box but need assistance with passing the correct values to the javascript and returning it to correct input box. existing code for working solution (first row works only, all other rows update first row input box) <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function lookup(inputString) { if(inputString.length == 0) { // Hide the suggestion box. $('#suggestions').hide(); } else { $.post("autocompleteperson.php", {queryString: ""+inputString+""}, function(data){ if(data.length >0) { $('#suggestions').show(); $('#autoSuggestionsList').html(data); } }); } } // lookup function fill(thisValue) { $('#inputString').val(thisValue); setTimeout("$('#suggestions').hide();", 200); } </script> </head> <body> <form name="form1" id="form1" action="addepartment.php" method="post"> <table> <? for ( $i = 1; $i <=10; $i++ ) { ?> <tr> <td> <? echo $i; ?></td> <td> <div> <input type="text" size="30" value="" id="inputString" onkeyup="lookup(this.value);" onblur="fill();" /> </div> <div class="suggestionsBox" id="suggestions" style="display: none;"> <img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" /> <div class="suggestionList" id="autoSuggestionsList"> &nbsp; </div> </div> </td> </tr> <? } ?> </table> </body> </html> code for autocompleteperson.php is: $query = $db->query("SELECT fullname FROM Persons WHERE fullname LIKE '$queryString%' LIMIT 10"); if($query) { while ($result = $query ->fetch_object()) { echo '<li onClick="fill(\''.$result->fullname.'\');">'.$result->fullname.'</li>'; } } in order to get it to work for all rows, I include the counter $i in each of the file names as below: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function lookup(inputString<? echo $i; ?>) { if(inputString<? echo $i; ?>.length == 0) { // Hide the suggestion box. $('#suggestions<? echo $i; ?>').hide(); } else { $.post("autocompleteperson.php", {queryString: ""+inputString<? echo $i; ?>+""}, function(data){ if(data.length >0) { $('#suggestions<? echo $i; ?>').show(); $('#autoSuggestionsList<? echo $i; ?>').html(data); } }); } } // lookup function fill(thisValue) { $('#inputString<? echo $i; ?>').val(thisValue); setTimeout("$('#suggestions<? echo $i; ?>').hide();", 200); } </script> </head> <body> <form name="form1" id="form1" action="addepartment.php" method="post"> <table> <? for ( $i = 1; $i <=10; $i++ ) { ?> <tr> <td> <? echo $i; ?></td> <td> <div> <input type="text" size="30" value="" id="inputString<? echo $i; ?>" onkeyup="lookup(this.value);" onblur="fill();" /> </div> <div class="suggestionsBox" id="suggestions<? echo $i; ?>" style="display: none;"> <img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" /> <div class="suggestionList" id="autoSuggestionsList<? echo $i; ?>"> &nbsp; </div> </div> </td> </tr> <? } ?> </table> </body> </html> The autocomplete suggestion works (although always shown on first row) but when selecting the data always returns to row 1, even if input was on row 5. I have a feeling this has to do with the fill() but not sure? is it due the the autocomplete page code? or does the fill referencing ThisValue have something to do with it. example of this page (as above) can be found here Thanks for the assistance, much appreciated. UPDATE - LOLO <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function lookup(i, inputString) { if(inputValue.length == 0) { // Hide the suggestion box. $('#suggestions' + i).hide(); } else { $.post("autocompleteperson.php", {queryString: ""+inputString+""}, function(data){ if(data.length >0) { $('#suggestions' + i).show(); $('#autoSuggestionsList' + i).html(data); } }); } } // lookup function fill(i, thisValue) { $('#inputString' + i).val(thisValue); setTimeout("$('#suggestions' + i).hide();", 200); } </script> </head> <body> <form name="form1" id="form1" action="addepartment.php" method="post"> <table> <? for ( $i = 1; $i <=10; $i++ ) { ?> <tr> <td> <? echo $i; ?></td> <td> <div> <input type="text" size="30" value="" id="inputString<?php echo $i; ?>" onkeyup="lookup(this.value);" onblur="fill();" /> </div> <div class="suggestionsBox" id="suggestions<? echo $i; ?>" style="display: none;"> <img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" /> <div class="suggestionList" id="autoSuggestionsList<? echo $i; ?>"> &nbsp; </div> </div> </td> </tr> <? } ?> </table> </body> </html> google chrome catched the following errors: first line on input, second line on loosing focus

  • Php code works on every browser but not on IE8, help please

  • header confusion. Compiler not recognizing datatypes

    - by numerical25
    I am getting confused on why the compiler is not recognizing my classes. So I am just going to show you my code and let you guys decide. My error is this error C2653: 'RenderEngine' : is not a class or namespace name and it's pointing to this line std::vector<RenderEngine::rDefaultVertex> m_verts; Here is the code for rModel, in its entirety.

In the end, I just need a good way to organize it so that rModel recognizes RenderEngine. and if possible, the other way around.

  • WCF Service returning 400 error: The body of the message cannot be read because it is empty

    - by Josh
    I have a WCF service that is causing a bit of a headache.

Here is the class. public class MyService : IMyService { IRDCService service; public MyService() { //service = new MySite.RDCService.RDCServiceClient(); EndpointAddress address = new EndpointAddress(APISettings.Default.ServiceUrl); BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None); binding.TransferMode = TransferMode.Streamed; binding.MaxBufferSize = 65536; binding.MaxReceivedMessageSize = 4194304; ChannelFactory<IRDCService> factory = new ChannelFactory<IRDCService>(binding, address); service = factory.CreateChannel(); } public Response<Customer> GetCustomer(CustomerRequest request) { return service.GetCustomer(request); } public Response<Customer> GetSiteCustomers(CustomerRequest request) { return service.GetSiteCustomers(request); } } and finally, the response object. [DataContract] public class Response<T> { [DataMember] public IEnumerable<T> Results { get; set; } [DataMember] public int TotalResults { get; set; } [DataMember] public int PageIndex { get; set; } [DataMember] public int PageSize { get; set; } [DataMember] public RulesException Exception { get; set; } } So, when I build my CustomerRequest object and pass it in, for some reason it's hitting the server as an empty request. Any ideas why? I've tried upping the object graph and the message size. When I debug it stops in the wrapper class with the 400 error. I'm not sure if there is a serialization error, but considering the object contract is 4 integer properties I can't imagine it causing an issue.

  • SINGLE SIGN ON SECURITY THREAT! FACEBOOK access_token broadcast in the open/clear

    - by MOKANA
    Subsequent to my posting there was a remark made that this was not really a question but I thought I did indeed postulate one. So that there is no ambiquity here is the question with a lead in: Since there is no data sent from Facebook during the Canvas Load process that is not at some point divulged, including the access_token, session and other data that could uniquely identify a user, does any one see any other way other than adding one more layer, i.e., a password, sent over the wire via HTTPS along with the access_toekn, that will insure unique untampered with security by the user? Using Wireshark I captured the local broadcast while loading my Canvas Application page. I was hugely surprised to see the access_token broadcast in the open, viewable for any one to see. This access_token is appended to any https call to the Facebook OpenGraph API. Using facebook as a single click log on has now raised huge concerns for me. It is stored in a session object in memory and the cookie is cleared upon app termination and after reviewing the FB.Init calls I saw a lot of HTTPS calls so I assumed the access_token was always encrypted. But last night I saw in the status bar a call from what was simply an http call that included the App ID so I felt I should sniff the Application Canvas load sequence. Today I did sniff the broadcast and in the attached image you can see that there are http calls with the access_token being broadcast in the open and clear for anyone to gain access to. Am I missing something, is what I am seeing and my interpretation really correct. If any one can sniff and get the access_token they can theorically make calls to the Graph API via https, even though the call back would still need to be the site established in Facebook's application set up. But what is truly a security threat is anyone using the access_token for access to their own site. I do not see the value of a single sign on via Facebook if the only thing that was established as secure was the access_token - becuase for what I can see it clearly is not secure. Access tokens that never have an expire date do not change. Access_tokens are different for every user, to access to another site could be held tight to just a single user, but compromising even a single user's data is unacceptable. http://www.creatingstory.com/images/InTheOpen.png Went back and did more research on this: FINDINGS: Went back an re ran the canvas application to verify that it was not any of my code that was not broadcasting. In this call: HTTP GET /connect.php/en_US/js/CacheData HTTP/1.1 The USER ID is clearly visible in the cookie. So USER_ID's are fully visible, but they are already. Anyone can go to pretty much any ones page and hover over the image and see the USER ID. So no big threat. APP_ID are also easily obtainable - but . . . http://www.creatingstory.com/images/InTheOpen2.png The above file clearly shows the FULL ACCESS TOKEN clearly in the OPEN via a Facebook initiated call. Am I wrong. TELL ME I AM WRONG because I want to be wrong about this. I have since reset my app secret so I am showing the real sniff of the Canvas Page being loaded. Additional data 02/20/2011: @ifaour - I appreciate the time you took to compile your response. I am pretty familiar with the OAuth process and have a pretty solid understanding of the signed_request unpacking and utilization of the access_token. I perform a substantial amount of my processing on the server and my Facebook server side flows are all complete and function without any flaw that I know of. The application secret is secure and never passed to the front end application and is also changed regularly. I am being as fanatical about security as I can be, knowing there is so much I don’t know that could come back and bite me. Two huge access_token issues: The issues concern the possible utilization of the access_token from the USER AGENT (browser). During the FB.INIT() process of the Facebook JavaScript SDK, a cookie is created as well as an object in memory called a session object. This object, along with the cookie contain the access_token, session, a secret, and uid and status of the connection. The session object is structured such that is supports both the new OAuth and the legacy flows. With OAuth, the access_token and status are pretty much al that is used in the session object. The first issue is that the access_token is used to make HTTPS calls to the GRAPH API. If you had the access_token, you could do this from any browser: https://graph.facebook.com/220439?access_token=... and it will return a ton of information about the user. So any one with the access token can gain access to a Facebook account. You can also make additional calls to any info the user has granted access to the application tied to the access_token. At first I thought that a call into the GRAPH had to have a Callback to the URL established in the App Setup, but I tested it as mentioned below and it will return info back right into the browser. Adding that callback feature would be a good idea I think, tightens things up a bit. The second issue is utilization of some unique private secured data that identifies the user to the third party data base, i.e., like in my case, I would use a single sign on to populate user information into my database using this unique secured data item (i.e., access_token which contains the APP ID, the USER ID, and a hashed with secret sequence). None of this is a problem on the server side. You get a signed_request, you unpack it with secret, make HTTPS calls, get HTTPS responses back. When a user has information entered via the USER AGENT(browser) that must be stored via a POST, this unique secured data element would be sent via HTTPS such that they are validated prior to data base insertion. However, If there is NO secured piece of unique data that is supplied via the single sign on process, then there is no way to guarantee unauthorized access. The access_token is the one piece of data that is utilized by Facebook to make the HTTPS calls into the GRAPH API. it is considered unique in regards to BOTH the USER and the APPLICATION and is initially secure via the signed_request packaging. If however, it is subsequently transmitted in the clear and if I can sniff the wire and obtain the access_token, then I can pretend to be the application and gain the information they have authorized the application to see. I tried the above example from a Safari and IE browser and it returned all of my information to me in the browser. In conclusion, the access_token is part of the signed_request and that is how the application initially obtains it. After OAuth authentication and authorization, i.e., the USER has logged into Facebook and then runs your app, the access_token is stored as mentioned above and I have sniffed it such that I see it stored in a Cookie that is transmitted over the wire, resulting in there being NO UNIQUE SECURED IDENTIFIABLE piece of information that can be used to support interaction with the database, or in other words, unless there were one more piece of secure data sent along with the access_token to my database, i.e., a password, I would not be able to discern if it is a legitimate call. Luckily I utilized secure AJAX via POST and the call has to come from the same domain, but I am sure there is a way to hijack that. I am totally open to any ideas on this topic on how to uniquely identify my USERS other than adding another layer (password) via this single sign on process or if someone would just share with me that I read and analyzed my data incorrectly and that the access_token is always secure over the wire. Mahalo nui loa in advance.

  • gzip not working for some files using nginx

    - by shakalandy
    Some files are not gzipped on their way to the user browser in our setup. for example http://myhostname.com/css/build/20120904-1.css http://myhostname.com/js/dojo/dn/main.js?20120904-1 http://myhostname.com/js/jquery-min/compiled.js?20120725-4 can not be zipped. my current configuration: location ~* \.(js|css|png|jpg|jpeg|gif|ico)\.*+$ { if ($args ~ [0-9]\.*+) { expires max; break; } expires max; log_not_found off; gzip on; } What needs to be adjusted to make gzip fly? I already tried several other options but don't want to continue with try&error on this. Thank you very much.

  • Installing sublime text plugins all at once

    - by James
    Is there a way to install all the sublime text 2 plugins that you would like to install all at once. In Notepad++, there is a plugin manager which lets you install all the plugins you want to install by checking the box next to the plugin name & description. I was wandering if there is something like that for sublime text. For eg, I would like to install Zen Coding, JQuery Package for Sublime Text, Sublime Prefixr, JS Format, SublimeLinter and many other plugins all at once rather than typing each plugin in the Package Control and installing it one by one.

  • How to simulate slow internet connection

    - by V-Light
    I currently deploy with GAE (google app engine) and I try to implement some AJAX validation. So I got a couple text-fields and "spinners" (ajax loaders) which should be displayed when an AJAX request is sent. But I deploy on my local computer (localhost), so the GAE SDK reacts very fast on any request. It takes about 50-70 ms(miliseconds) to perform the whole ajax request, which is far far away from the real. Is there a way to somehow simulate slow Internet connection? I just want to see how my "spinners" work. I want to test some ajax setting (jquery) about timeouts, errors and so on... Any ideas ?

  • Strange Windows DIR command behavior

    - by user1167442
    I discovered this quite by accident while looking for a file with a number in the name. When I type: dir *number* (where number represents any number from 0 to 9 and with no spaces between the asterisks and the number) at the cmd.exe command prompt, it returns various files do not appear in any to fit the search criteria. What's weird, is that depending on the directory, some numbers will work and not others. An example is, in a directory associated with a website, I type the following: dir *4* and what is returned is: Directory of C:\Ampps\www\includes\pages 04/30/2012 03:55 PM 153 inventory_list_retrieve.php 06/18/2012 11:17 AM 6,756 ix.html 06/19/2012 01:47 PM 257,501 jquery.1.7.1.js 3 File(s) 264,410 bytes 0 Dir(s) 362,280,906,752 bytes free That just doesn't make any sense to me. Any clue? The question is posed on stackOverflow because the DIR command is often combined with FOR in batch programs. The strange DIR behavior would seem to make batch programs potentially unreliable if they use the DIR command.

  • Is it me or is developing web based data entry GUIs a big pain?

    - by GregH
    Maybe it's me or maybe it isn't. I don't have a huge amount of experience of developing web based data entry software but do have some. I used to do it quite a bit years ago. Used to use Oracle Forms, Visual Studio, various 4th generation languages, and performing the user interface layout used to be a snap. Now doing the user interface for developing web applications seems to be a huge pain in the rear. Just trying to get text entry fields and widgets to go where they are supposed to go on the screen is a total pain. You have to know Javascript, CSS, JQuery, HTML, etc. There must be an easier way to develop data entry forms that produce the needed underlying code for a web page. Maybe I'm just not looking in the right place. There must be some WYSIWYG GUI development tools for the web for developing data entry forms out there. Anybody know of any?

  • Tips on Managing Podcast Subscriptions

    - by Ben Griswold
    I listen to a silly number of technical podcasts. I listen to enough of them that it is literally impossible to keep up. I nearly gave up and started dropping feeds from my subscription list when I heard Craig Shoemaker talk about his Polymorphic Podcast fast feed. The idea is he provides the same content at a higher speed so you can listen to his complete show in 3/4th the time. I tried it out with his recent jQuery Secrets with Dave Ward interview and I was shocked with the feed quality. It was a super clear, understandable conversation which only took a fraction of the time commitment. I experimented a bit and played the normal recording at 2x speed on my iPhone and the quality was once again just fine. But now I'm saving half of the time. I'm curious as to how you might manage your podcast subscriptions. Can you offer any tips or advice on how to get the best bang for your buck when it comes to technical podcast listening?

  • Why is my system waiting for google-analytics?

    - by mikeroosa
    When I go to certain websites that have google analytics, they never load up. One example is www.jquery.com. I tried in firefox, chrome, safari and explorer. Chrome & safari, flash the home page then it disappears and the screen goes white. Firefox never loads anything and the spinner just keeps spinning. Loads fine in explorer. Any ideas of what may be going on? If I use my laptop, on my same home internet connection, it works fine. This is not happening on all sites with analytics, just certain ones.
