  • beforeClose not working in jGrowl?

    - by sparkymark75
    I have the following code which pulls json data from an ASP.NET page and displays these as notifications. The code will also take a note of what's been pulled through and store it in an array to prevent it being shown again in the same session. I'm now trying to implement functionality so that when the user closes a message, it's ID is recorded in a cookie to prevent it ever being shown again. To do this, I'm trying to write to the cookie when the beforeClose event fires. Everything else works fine apart from the saving to a cookie bit. Is there something wrong with my code that I'm missing? var alreadyGrowled = new Array(); var noteCookie = $.cookie("notificationsViewed"); if (noteCookie != null) { alreadyGrowled = noteCookie.split(","); } function growlCheckNew() { $.getJSON('getNotifications.aspx', function(data) { $(data).each(function(entryIndex, entry) { var newMessage = true; $(alreadyGrowled).each(function(index, msg_id) { if (entry['ID'] == msg_id) { newMessage = false; } }); if (newMessage == true) { $.jGrowl(entry['Message'], { sticky: true, header: entry['Title'], beforeClose: function(e, m) { $.cookie("notificationsViewed", entry['ID']); } }); } alreadyGrowled.push(entry['ID']); }); }); }

  • segmentation fault in file operations in c

  • How can I load combo box's data when it has been defined in DataTemplate codebehind ?

    - by Naseem
    Hi, In my silverlight application,I need to have dynamic columns in my DataGrid . So I had to create all the columns and their DataTemplate dynamically .When user wants to edit the column , a combo box will be displayed which has different values based on selected column. For creating each column I have wrote : foreach (var itemFilter in ProductFilterCollection) { DataGridTemplateColumn templateColumn = new DataGridTemplateColumn(); templateColumn.Header = itemFilter.Description.ToString(); templateColumn.CellTemplate = CreateCellTemplate(typeof(TextBlock), itemFilter.Description.ToString()); templateColumn.CellEditingTemplate = CreateEditingTemplate(typeof(ComboBox), itemFilter.Description.ToString()); grdTest.Columns.Add(templateColumn); } Here is the code for creating DataTemplate dynamically. public DataTemplate CreateCellTemplate(Type type, string strBinding) { return (DataTemplate)XamlReader.Load(@"<DataTemplate xmlns=""http://schemas.microsoft.com/client/2007""> <" + type.Name + @" Text=""{Binding " + strBinding + @"}""/> </DataTemplate>"); } public DataTemplate CreateEditingTemplate(Type type, string strBinding) { return (DataTemplate)XamlReader.Load(@"<DataTemplate xmlns=""http://schemas.microsoft.com/client/2007""> <" + type.Name + @" Loaded=""ddlTest_Loaded"" Tag=""{Binding " + strBinding + @"}""/> </DataTemplate>"); } I need to use Loaded="ddlTest_Loaded" in CreateEditingTemplate() ,in order to load the combo box . However it causes exception . When I remove Loaded event it's fine however the combo box is empty. How can I load the combo box when I define it in DataTemplate codebehind.

  • What -W values in gcc correspond to which actual warnings?

    - by SebastianK
    Preamble: I know, disabling warnings is not a good idea. Anyway, I have a technical question about this. Using GCC 3.3.6, I get the following warning: choosing ... over ... because conversion sequence for the argument is better. Now, I want to disable this warning as described in gcc warning options by providing an argument like -Wno-theNameOfTheWarning But I don't know the name of the warning. How can I find out the name of the option that disables this warning? I am not able to fix the warning, because it occurs in a header of an external library that can not be changed. It is in boost serialization (rx(s, count)): template<class Archive, class Container, class InputFunction, class R> inline void load_collection(Archive & ar, Container &s) { s.clear(); // retrieve number of elements collection_size_type count; unsigned int item_version; ar >> BOOST_SERIALIZATION_NVP(count); if(3 < ar.get_library_version()) ar >> BOOST_SERIALIZATION_NVP(item_version); else item_version = 0; R rx; rx(s, count); std::size_t c = count; InputFunction ifunc; while(c-- > 0){ ifunc(ar, s, item_version); } } I have already tried #pragma GCC system_header but this had no effect. Using -isystem instead of -I also does not work. The general question remains is: I know the text of the warning message. But I do not know the correlation to the gcc warning options.

  • Add an item to the Finder/Save dialog sidebar

    - by Clinton Blackmore
    I'm working on a script where a user logs into a guest account on OS and is prompted for their network credentials in order to mount their network home folder (while they benefit from working on a local user folder). As the guest folder is deleted when users log out, I want to discourage them from saving anything there. I would like to replace the items on the Finder and Open/Save sidebar lists (such as "Desktop", username, "Documents", etc) with ones that would save into their network home folder. It is possible to do this using AppleScript or Cocoa APIs, or do I need to modify a plist and restart the Finder? [Ack. Looking into ~/Library/Preferences/com.apple.sidebars.plist, it isn't at all clear how I'd populate it.] Similar Questions: AppleScript: adding mounted folder to Finder Sidebar? suggests using fstab; this code will most likely run as a user and really, automounting at that point would be too late. How do you programmatically put folder icons on the Finder sidebar, given that you have to use a custom icon for the folder? Says there is no Cocoa API, but that you can use a carbon-style LSSharedFileList API that is only documented in a single header file. Does anyone know of some example code to add an item to the Finder sidebar?

  • PHP Cookie Warning...

    - by Nano HE
    Hi,I am new to PHP, I practised PHP setcookie() just now and failed. http://localhost/test/index.php <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title></title> </head> <body> <?php $value = 'something from somewhere'; setcookie("TestCookie", $value); ?> </body> </html> http://localhost/test/view.php <?php // I plan to view the cookie value via view.php echo $_COOKIE["TestCookie"]; ?> But I failed to run index.php, IE warning like this. Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\test\index.php:9) in C:\xampp\htdocs\test\index.php on line 12 I enabled my IE 6 cookie no doubt. Is there anything wrong on my procedure above? Thank you. WinXP OS and XAMPP 1.7.3 used.

  • Updating Android Tab Icons

    - by lnediger
    I have an activity which has a TabHost containing a set of TabSpecs each with a listview containing the items to be displayed by the tab. When each TabSpec is created, I set an icon to be displayed in the tab header. The TabSpecs are created in this way within a setupTabs() method which loops to create the appropriate number of tabs: TabSpec ts = mTabs.newTabSpec("tab"); ts.setIndicator("TabTitle", iconResource); ts.setContent(new TabHost.TabContentFactory( { public View createTabContent(String tag) { ... } }); mTabs.addTab(ts); There are a couple instances where I want to be able to change the icon which is displayed in each tab during the execution of my program. Currently I am deleting all the tabs, and calling the above code again to re-create them. mTabs.getTabWidget().removeAllViews(); mTabs.clearAllTabs(true); setupTabs(); Is there a way to replace the icon that is being displayed without deleting and re-creating all of the tabs?

  • MinGW-gcc PCH not speeding up wxWidget build times. Is my setup correct?

    - by Victor T.
    Hi all, I've been building wxMSW 2.8.11 with the latest stable release of mingw-gcc 4.5.1 and I'm trying to see if the build could be sped up using precompiled headers. My initial attempts at this doesn't seem to work. I basically followed the given instructions here. I created a wxprec.h precompiled header with the following: g++ -O2 -mthreads -DHAVE_W32API_H -D__WXMSW__ -DNDEBUG -D_UNICODE -I..\..\lib\gcc_dll\mswu -I..\..\include -W -Wall -DWXBUILDING -I..\.. \src\tiff -I..\..\src\jpeg -I..\..\src\png -I..\..\src\zlib -I..\..\src \regex -I..\..\src\expat\lib -DwxUSE_BASE=1 -DWXMAKINGDLL -Wno-ctor- dtor-privacy ../../include/wx/wxprec.h That does successfully create a wxprec.h.gch that's about ~1.6meg in size. Now I proceed to build wxmsw using the follow make command from cmd.exe shell: mingw32-make -f makefile.gcc While, the build does succeed I noticed no speedup whatsoever then if pch wasn't used. To make sure gcc was actually using the pch I added -H in the config.gcc and did another rebuild. Indeed, the outputted include list does show a '!' next to the wxprec.h so gcc is supposely using it. What's the reason for pch not working? Did I setup the precompiled headers correctly or am I missing a step? Just for reference comparison, here's the compile times I get when building wxmsw 2.8.11 with the other compilers(visual studio 2010 and C++ Builder 2007). The time savings is pretty significant. | | release, pch | release, nopch | debug, nopch ------------------------------------------------------- | gcc451 | 8min 33sec | 8min 17sec | 8min 49sec | msc_1600 | 2min 23sec | 13min 11sec | -- | bcc593 | 0min 59sec | 2min 29sec | -- Thanks

  • AppFabric caching's local cache isnt working for us... What are we doing wrong?

    - by Olly
    We are using appfabric as the 2ndlevel cache for an NHibernate asp.net application comprising a customer facing website and an admin website. They are both connected to the same cache so when admin updates something, the customer facing site is updated. It seems to be working OK - we have a CacheCLuster on a seperate server and all is well but we want to enable localcache to get better performance, however, it dosnt seem to be working. We have enabled it like this... bool UseLocalCache = int LocalCacheObjectCount = int.MaxValue; TimeSpan LocalCacheDefaultTimeout = TimeSpan.FromMinutes(3); DataCacheLocalCacheInvalidationPolicy LocalCacheInvalidationPolicy = DataCacheLocalCacheInvalidationPolicy.TimeoutBased; if (UseLocalCache) { configuration.LocalCacheProperties = new DataCacheLocalCacheProperties( LocalCacheObjectCount, LocalCacheDefaultTimeout, LocalCacheInvalidationPolicy ); // configuration.NotificationProperties = new DataCacheNotificationProperties(500, TimeSpan.FromSeconds(300)); } Initially we tried using a timeout invalidation policy (3mins) and our app felt like it was running faster. HOWEVER, we noticed that if we changed something in the admin site, it was immediatley updated in the live site. As we are using timeouts not notifications, this demonstrates that the local cache isnt being queried (or is, but is always missing). The cache.GetType().Name returns "LocalCache" - so the factory has made a local cache. Running "Get-Cache-Statistics MyCache" in PS on my dev environment (asp.net app running local from vs2008, cache cluster running on a seperate w2k8 machine) show a handful of Request Counts. However, on the Production environment, the Request Count increases dramaticaly. We tried following the method here to se the cache cliebt-server traffic... http://blogs.msdn.com/b/appfabriccat/archive/2010/09/20/appfabric-cache-peeking-into-client-amp-server-wcf-communication.aspx but the log file had nothing but the initial header in it - i.e no loggin either. I cant find anything in SO or Google. Have we done something wrong? Have we got a screwy install of AppFabric - we installed it via WebPlatform Installer - I think? (note: the IIS box running ASp.net isnt in yhe cluster - it is just the client). Any insights greatfully received!

  • php not redirecting

    - by NSchulze
    I'm trying to write the logout of a website. When I do this I want the page to redirect to the login page. I think I'm doing it the correct way, but can't get the right result. Could you guys point me in the right direction? Relevant Code: <button onclick="logout()">Logout</button> function logout() { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.location=xmlhttp.responseText; } } xmlhttp.open("GET","logout.php",true); xmlhttp.send(); } <?php session_destroy(); header("Location:http://localhost:8888/loginns.html"); mysql_close($con); ?> Thanks!

  • Visual C++ doesn't operator<< overload

    - by PierreBdR
    I have a vector class that I want to be able to input/output from a QTextStream object. The forward declaration of my vector class is: namespace util { template <size_t dim, typename T> class Vector; } I define the operator<< as: namespace util { template <size_t dim, typename T> QTextStream& operator<<(QTextStream& out, const util::Vector<dim,T>& vec) { ... } template <size_t dim, typename T> QTextStream& operator>>(QTextStream& in,util::Vector<dim,T>& vec) { .. } } However, if I ty to use these operators, Visual C++ returns this error: error C2678: binary '<<' : no operator found which takes a left-hand operand of type 'QTextStream' (or there is no acceptable conversion) A few things I tried: Originaly, the methods were defined as friends of the template, and it is working fine this way with g++. The methods have been moved outside the namespace util I changed the definition of the templates to fit what I found on various Visual C++ websites. The original friend declaration is: friend QTextStream& operator>>(QTextStream& ss, Vector& in) { ... } The "Visual C++ adapted" version is: friend QTextStream& operator>> <dim,T>(QTextStream& ss, Vector<dim,T>& in); with the function pre-declared before the class and implemented after. I checked the file is correctly included using: #pragma message ("Including vector header") And everything seems fine. Doesn anyone has any idea what might be wrong?

  • Strange problem with PHP and sessions

    - by Jhorra
    So the basis of this page is I set a session value when the page loads, and clear it on any other page they visit. Then the page can make an ajax call to download a file. If the session value matches the value I pass through the URL I allow them to download the file. If not I return a 404 error. I was having some weird issues, so I removed the 404 and set it to echo out the values instead to see what I was getting. Here is the top of the code on the page: $code = $this->_request->getParam('code'); $confirm = $_SESSION['mp3_code']; echo $code."-1-".$confirm; if($code != $confirm) echo $code."-2-".$confirm;//header("HTTP/1.1 404 Not Found"); else { Here is what displays on the page from the ajax call 12723430-1-12723430-2- As you can see when it echos out the first time they exist, then somehow after I compare them and it fails you see that it echos out blank values like they suddenly ceased to exist. Any ideas?

  • Extracting function declarations from a PHP file

    - by byronh
    I'm looking to create an on-site API reference for my framework and application. Basically, say I have a class file model.class.php: class Model extends Object { ... code here ... // Separates results into pages. // Returns Paginator object. final public function paginate($perpage = 10) { ... more code here ... } } and I want to be able to generate a reference that my developers can refer to quickly in order to know which functions are available to be called. They only need to see the comments directly above each function and the declaration line. Something like this (similar to a C++ header file): // Separates results into pages. // Returns Paginator object. final public function paginate($perpage = 10); I've done some research and this answer looked pretty good (using Reflection classes), however, I'm not sure how I can keep the comments in. Any ideas? EDIT: Sorry, but I want to keep the current comment formatting. Myself and the people who are working on the code hate the verbosity associated with PHPDocumentor. Not to mention a comment-rewrite of the entire project would take years, so I want to preserve just the // comments in plaintext.

  • ISO C++ forbids declaration of 'QPushButton' with no type in QT Creator

    - by Mohit Deshpande
    I am running QT Creator on a Linux Ubuntu 9.10 machine. I just got started with QT Creator, and I was going through the tutorials when this error popped up while I was trying to build my project: "ISO C++ forbids declaration of 'QPushButton' with no type". This problem appears in my header file: #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui/QWidget> namespace Ui { class MainWindow; } class MainWindow : public QWidget { Q_OBJECT public: MainWindow(QWidget *parent = 0); ~MainWindow(); public slots: void addContact(); void submitContact(); void cancel(); private: Ui::MainWindow *ui; QPushButton *addButton; QPushButton *submitButton; QPushButton *cancelButton; QLineEdit *nameLine; QTextEdit *addressText; QMap<QString, QString> contacts; QString oldName; QString oldAddress; }; #endif // MAINWINDOW_H

  • Returning HTML in the JS portion of a respond_to block throws errors in IE

    - by Horace Loeb
    Here's a common pattern in my controller actions: respond_to do |format| format.html {} format.js { render :layout => false } end I.e., if the request is non-AJAX, I'll send the HTML content in a layout on a brand new page. If the request is AJAX, I'll send down the same content, but without a layout (so that it can be inserted into the existing page or put into a lightbox or whatever). So I'm always returning HTML in the format.js portion, yet Rails sets the Content-Type response header to text/javascript. This causes IE to throw this fun little error message: Of course I could set the content-type of the response every time I did this (or use an after_filter or whatever), but it seems like I'm trying to do something relatively standard and I don't want to add additional boilerplate code. How do I fix this problem? Alternatively, if the only way to fix the problem is to change the content-type of the response, what's the best way to achieve the behavior I want (i.e., sending down content with layout for non-AJAX and the same content without a layout for AJAX) without having to deal with these errors? Edit: This blog post has some more info

  • How to debug an external library (OpenCV) in Visual C++?

    - by neuviemeporte
    I am developing a project in VC++2008. The project uses the OpenCV library (but I guess this applies to any other library). I am working with the Debug configuration, the linker properties include the debug versions of the library .lib's as additional dependencies. In VC++ Directories under Tools|Options i set up the include directory, the .lib directory, the source directories for the library as well. I get an error while calling one of the functions from the library and I'd like to see exactly what that function is doing. The line that produces the error is: double error = cvStereoCalibrate(&calObjPointsM, &img1PointsM, &img2PointsM, &pointCountsM, &cam1M, &dist1M, &cam2M, &dist2M, imgSize, &rotM, &transM, NULL, NULL, cvTermCriteria(CV_TERMCRIT_ITER + CV_TERMCRIT_EPS, 100, 1e-5)); I set up a breakpoint at this line to see how the cvStereoCalibrate() function fails. Unfortunately the debugger won't show the source code for this function when I hit "Step into". It skips immediately to the cvTermCriteria() (which is a simple inline, macro-kinda function) and show its contents. Is there anything else I need to do to be able to enter the external library functions in the debugger? EDIT: I think the cvTermCriteria() function shows in the debugger, because it's defined in a header file, therefore immediately accesible to the project.

  • Why doesn't this for-loop execute?

    - by Maulrus
    I'm writing a program for an exercise that will read data from a file and format it to be readable. So far, I have a bit of code that will separate a header from the data that goes under it. Here it is: int main() { ifstream in("records.txt"); ofstream out("formatted_records.txt"); vector<string> temp; vector<string> headers; for (int i = 0; getline(in,temp[i]); ++i) { static int k = -1; if (str_isalpha(temp[i])) { headers[++k] = temp[i]; temp.erase(temp.begin() + i); } else { temp[i] += "," + headers[k]; } } } (str_isalpha() is just a function that applies isalpha() to every character in a string.) Now, the for-loop in this program doesn't execute, and I can't figure out why. Does anybody know?

  • Why aren't these Canvases rendering?

    - by bpapa
    I'm creating a web app that allows users to enter a number of colors, by specifying RGB values. Upon submission, the user will see a canvas with a solid rectangle drawn in the color chosen. On this page, I have 7 canvases. The first one draws just fine, but none of the rest show up. The browser is Safari. Here's the relevant code: First, the script element in the header, which defines the function I use to draw to the canvas. <script language="JavaScript" TYPE="text/javascript"><!-- function drawCanvas(canvasId, red, green, blue) { var theCanvas = document.getElementById("canvas" + canvasId); var context = theCanvas.getContext("2d"); context.clearRect(0,0,100,100); context.setFillColor(red,green,blue,1.0); context.fillRect(0,0,100,100); } // --> </script> Next, the HTML source, where I have my canvas tags and some embedded Javascript to call my drawCanvas function <canvas id="canvas0" width="100" height="100"> </canvas> <script language="JavaScript" TYPE="text/javascript"><!-- drawCanvas(0,250,0,0); // --> </script> . . //more source . <canvas id="canvas1" width="100" height="100"> </canvas> <script language="JavaScript" TYPE="text/javascript"><!-- drawCanvas(1,4,250,6); // --> </script> Also provided is a screenshot. As you can see, the "red" canvas comes up just fine, but the second one, which should be green, doesn't show up at all. Any ideas?

  • How do I enable mod_deflate for PHP files?

    - by DM.
    I have a Liquid Web VPS account, I've made sure that mod_deflate is installed and running/active. I used to gzip my css and js files via PHP, as well as my PHP files themselves... However, I'm now trying to do this via mod_deflate, and it seems to work fine for all files except for PHP files. (Txt files work fine, css, js, static HTML files, just nothing that is generated via a PHP file.) How do I fix this? (I used the "Compress all content" option under "Optimize Website" in cPanel, which creates an .htaccess file in the home directory (not public_html, one level higher than that) with exactly the same text as the "compress everything except images" example on http://httpd.apache.org/docs/2.0/mod/mod_deflate.html) .htaccess file: <IfModule mod_deflate.c> SetOutputFilter DEFLATE <IfModule mod_setenvif.c> # Netscape 4.x has some problems...

I know only Turbo C++, so it would be helpfull for me if u provide solution or suggestion related to topic for the same. int main() { ifstream fr; //reads ofstream fw; // wrrites to file char c; int random; clrscr(); char file[2][100]={"s.bmp","s.txt"}; fr.open(file[0],ios::binary);//file name, mode of open, here input mode i.e. read only if(!fr) cout<<"File can not be opened."; fw.open(file[1],ios::app);//file will be appended if(!fw) cout<<"File can not be opened"; while(!fr) cout<<fr.get(); // error should be here. but not able to find out what error is it fr.close(); fw.close(); getch(); } This code is running fine when i pass txt file in binary mode

  • Decompress a GZipped response from the server (Socket)

    - by Lith
    Umm, ok, after sending some data to the server, noting this particular part: "Accept-Encoding: gzip,deflate\r\n" I am getting the following response: HTTP/1.1 200 OK Server: nginx Date: Fri, 09 Apr 2010 23:25:27 GMT Content-Type: text/html; charset=UTF-8 Transfer-Encoding: chunked Connection: keep-alive X-Powered-By: PHP/5.2.8 Expires: Mon, 26 Jul 1997 05:00:00 GMT Last-Modified: Fri, 09 Apr 2010 23:25:27 GMT Cache-Control: no-store, no-cache, must-revalidate Cache-Control: post-check=0, pre-check=0 Pragma: no-cache Content-Encoding: gzip Vary: Accept-Encoding 7aa ??U-?Rh?%?2?w??PM]??7?qZ?K?)???2?&??m???"q??/p9w?????x?[`tA!G???G?5z??????a>k????????Q ???N?? ('??f?,(??Y:5B???-?)?3x^0e:j?`,???**???F>G)?2????@???b??????A?k???Ar?n? But how do I decompress it? Note that I am using the Socket Class to do all the work. I know how to decompress it, but the problem here lies in the fact that I cannot separate the Packet from the GZipped data, psuedo-psuedocode (or whatever) on how I do it: Socket sends packet; Socket reads response from server, stores into a ByteArray; Create MemoryStream, use ByteArray; Create GZipStream, use Memorystream; now the problem occurs; I am getting the following Error: System.IO.InvalidDataException The magic number in GZip header is not correct. Make sure you are passing in a GZip stream. I hope the explanation is clear enough __.

  • Extract data from PostgreSQL DB without using pg_dump

    - by John Horton
    There is a PostgreSQL database on which I only have limited access (e.g, I can't use pg_dump). I am trying to create a local "mirror" by exporting certain tables from the database. I do not have the permissions needed to just dump a table as SQL from within psql. Right now, I just have a Python script that iterates through my table_names, selects all fields and then exports them as a CSV: for table_name, file_name in zip(table_names, file_names): cmd = """echo "\\\copy (select * from %s)" to stdout WITH CSV HEADER | psql -d remote_db | gzip > ./%s/%s.gz"""%(table_name,dir_name,file_name) os.system(cmd) I would like to not use CSV if possible, as I lose the field types and the encoding can get messed up. First best would probably be some way of getting the generating SQL code for the table using \copy. Next best would be XML, ideally with some way of preserving the field types. If that doesn't work, I think the final option might be two queries---one to get the field data types, the other to get the actual data. Any thoughts or advice would be greatly appreciated - thanks!

  • php: autoload exception handling.

    - by YuriKolovsky
    Hello again, I'm extending my previous question (Handling exceptions within exception handle) to address my bad coding practice. I'm trying to delegate autoload errors to a exception handler. <?php function __autoload($class_name) { $file = $class_name.'.php'; try { if (file_exists($file)) { include $file; }else{ throw new loadException("File $file is missing"); } if(!class_exists($class_name,false)){ throw new loadException("Class $class_name missing in $file"); } }catch(loadException $e){ header("HTTP/1.0 500 Internal Server Error"); $e->loadErrorPage('500'); exit; } return true; } class loadException extends Exception { public function __toString() { return get_class($this) . " in {$this->file}({$this->line})".PHP_EOL ."'{$this->message}'".PHP_EOL . "{$this->getTraceAsString()}"; } public function loadErrorPage($code){ try { $page = new pageClass(); echo $page->showPage($code); }catch(Exception $e){ echo 'fatal error: ', $code; } } } $test = new testClass(); ?> the above script is supposed to load a 404 page if the testClass.php file is missing, and it works fine, UNLESS the pageClass.php file is missing as well, in which case I see a "Fatal error: Class 'pageClass' not found in D:\xampp\htdocs\Test\PHP\errorhandle\index.php on line 29" instead of the "fatal error: 500" message I do not want to add a try/catch block to each and every class autoload (object creation), so i tried this. What is the proper way of handling this?
