  • How can I display a language according to the user's browser's language inside this code?

    - by janoChen
    How can I display a language according to the user's browser's language inside this mini-framework for my multilingual website? Basically, it has to display the default language of the user if there's no cookies. Example of index.php: (rendered output) <h2><?php echo l('tagline_h2'); ?></h2> common.php: (controller of which language to output) <?php session_start(); header('Cache-control: private'); // IE 6 FIX if(isSet($_GET['lang'])) { $lang = $_GET['lang']; // register the session and set the cookie $_SESSION['lang'] = $lang; setcookie("lang", $lang, time() + (3600 * 24 * 30)); } else if(isSet($_SESSION['lang'])) { $lang = $_SESSION['lang']; } else if(isSet($_COOKIE['lang'])) { $lang = $_COOKIE['lang']; } else { $lang = 'en'; } //use appropiate lang.xx.php file according to the value of the $lang switch ($lang) { case 'en': $lang_file = 'lang.en.php'; break; case 'es': $lang_file = 'lang.es.php'; break; case 'tw': $lang_file = 'lang.tw.php'; break; case 'cn': $lang_file = 'lang.cn.php'; break; default: $lang_file = 'lang.en.php'; } //translation helper function function l($translation) { global $lang; return $lang[$translation]; } include_once 'languages/'.$lang_file; ?> Example of /languages/lang.en.php: (where multilingual content is being stored) <?php $lang = array( 'tagline_h2' => '...',

  • Help me create a Firefox extension (Javascript XPCOM Component)

    - by Johnny Grass
    I've been looking at different tutorials and I know I'm close but I'm getting lost in implementation details because some of them are a little bit dated and a few things have changed since Firefox 3. I have already written the javascript for the firefox extension, now I need to make it into an XPCOM component. This is the functionality that I need: My Javascript file is simple, I have two functions startServer() and stopServer. I need to run startServer() when the browser starts and stopServer() when firefox quits. Edit: I've updated my code with a working solution (thanks to Neil). The following is in MyExtension/components/myextension.js. Components.utils.import("resource://gre/modules/XPCOMUtils.jsm"); const CI = Components.interfaces, CC = Components.classes, CR = Components.results; // class declaration function MyExtension() {} MyExtension.prototype = { classDescription: "My Firefox Extension", classID: Components.ID("{xxxx-xxxx-xxx-xxxxx}"), contractID: "@example.com/MyExtension;1", QueryInterface: XPCOMUtils.generateQI([CI.nsIObserver]), // add to category manager _xpcom_categories: [{ category: "profile-after-change" }], // start socket server startServer: function () { /* socket initialization code */ }, // stop socket server stopServer: function () { /* stop server */ }, observe: function(aSubject, aTopic, aData) { var obs = CC["@mozilla.org/observer-service;1"].getService(CI.nsIObserverService); switch (aTopic) { case "quit-application": this.stopServer(); obs.removeObserver(this, "quit-application"); break; case "profile-after-change": this.startServer(); obs.addObserver(this, "quit-application", false); break; default: throw Components.Exception("Unknown topic: " + aTopic); } } }; var components = [MyExtension]; function NSGetModule(compMgr, fileSpec) { return XPCOMUtils.generateModule(components); }

  • Capture *all* display-characters in JavaScript?

    - by Jean-Charles
    I was given an unusual request recently that I'm having the most difficult time addressing that involves capturing all display-characters when typed into a text box. The set up is as follows: I have a text box that has a maxlength of 10 characters. When the user attempts to type more than 10 characters, I need to notify the user that they're typing beyond the character count limit. The simplest solution would be to specify a maxlength of 11, test the length on every keyup, and truncate back down to 10 characters but this solution seems a bit kludgy. What I'd prefer to do is capture the character before keyup and, depending on whether or not it is a display-character, present the notification to the user and prevent the default action. A white-list would be challenging since we handle a lot of international data. I've played around with every combination of keydown, keypress, and keyup, reading event.keyCode, event.charCode, and event.which, but I can't find a single combination that works across all browsers. The best I could manage is the following that works properly in =IE6, Chrome5, FF3.6, but fails in Opera: NOTE: The following code utilizes jQuery. $(function(){ $('#textbox').keypress(function(e){ var $this = $(this); var key = ('undefined'==typeof e.which?e.keyCode:e.which); if ($this.val().length==($this.attr('maxlength')||10)) { switch(key){ case 13: //return case 9: //tab case 27: //escape case 8: //backspace case 0: //other non-alphanumeric break; default: alert('no - '+e.charCode+' - '+e.which+' - '+e.keyCode); return false; }; } }); }); I'll grant that what I'm doing is likely over-engineering the solution but now that I'm invested in it, I'd like to know of a solution. Thanks for your help!

  • Invalid argument supplied for foreach() using adldap

    - by Brad
    I am using adldap http://adldap.sourceforge.net/ And I am passing the session from page to page, and checking to make sure the username within the session is a member of a certain member group, for this example, it is the STAFF group. <?php ini_set('display_errors',1); error_reporting(E_ALL); require_once('/web/ee_web/include/adLDAP.php'); $adldap = new adLDAP(); session_start(); $group = "STAFF"; //$authUser = $adldap->authenticate($username, $password); $result=$adldap->user_groups($_SESSION['user_session']); foreach($result as $key=>$value) { switch($value) { case $group: print '<h3>'.$group.'</h3>'; break; default: print '<h3>Did not find specific value: '.$value.'</h3>'; } if($value == $group) { print 'for loop broke'; break; } } ?> It gives me the error: Warning: Invalid argument supplied for foreach() on line 15, which is this line of code: foreach($result as $key=$value) { When I uncomment the code $authUser = $adldap-authenticate($username, $password); and enter in the appropriate username and password, it works fine, but I shouldn't have to, since the session is valid, I just want to see if the username stored within the valid_session is apart of the STAFF group. Why would it be giving me that problem?

  • -[NSCFData writeStreamHandleEvent:]: unrecognized selector sent to instance in a stream callback

    - by user295491
    Hi everyone, I am working with streams and sockets in iPhone SDK 3.1.3 the issue is when the program accept a callback and I want to handle this writestream callback the following error is triggered " Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: ' -[NSCFData writeStreamHandleEvent:]: unrecognized selector sent to instance 0x17bc70'" But I don't know how to solve it because everything seems fine. Even when I run the debugger there is no error the program works. Any hint here will help! The code of the callback is: void myWriteStreamCallBack (CFWriteStreamRef stream, CFStreamEventType eventType, void *info){ NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [(Connection *)info retain] autorelease]; [handlerEv writeStreamHandleEvent:eventType]; [pool release]; } The code of the writeStreamHandleEvent: - (void)writeStreamHandleEvent:(CFStreamEventType) eventType{ switch(eventType) { case kCFStreamEventOpenCompleted: writeStreamOpen = YES; break; case kCFStreamEventCanAcceptBytes: NSLog(@"Writing in the stream"); [self writeOutgoingBufferToStream]; break; case kCFStreamEventErrorOccurred: error = CFWriteStreamGetError(writeStream); fprintf(stderr, "CFReadStreamGetError returned (%ld, %ld)\n", error.domain, error.error); CFWriteStreamUnscheduleFromRunLoop(writeStream, CFRunLoopGetCurrent(),kCFRunLoopCommonModes); CFWriteStreamClose(writeStream); CFRelease(writeStream); break; case kCFStreamEventEndEncountered: CFWriteStreamUnscheduleFromRunLoop(writeStream, CFRunLoopGetCurrent(),kCFRunLoopCommonModes); CFWriteStreamClose(writeStream); CFRelease(writeStream); break; } } The code of the stream configuration: CFSocketContext ctx = {0, self, nil, nil, nil}; CFWriteStreamSetClient (writeStream,registeredEvents, (CFWriteStreamClientCallBack)&myWriteStreamCallBack,(CFStreamClientContext *)(&ctx) ); CFWriteStreamScheduleWithRunLoop (writeStream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); You can see that there is nothing strange!, well at least I don't see it. Thank you in advance.

  • SEO - Problems possibly related to 301 Moved Permanently

    - by ILMV
    Right, here's the story: We have had a website for one of our brands now for many years, the site design was very bad and recently did a complete overhaul, mostly design, but also some of the backend code. The original site was using links such as this example.com/products/item/127 and thus I wanted to change them to be move user friendly, especially to include the product name, the same link now reads example.com/product/127/my-jucy-product/. Since our switch over we have seen our Google results take a beating (we were on the first page for our normal search terms, now we're nearer the 4th!). The other problem we're having is that the links to the old products haven't updated to the new links despite me coding a 301 redirect from old to new. The 301 is not being fired from .htaccess, but in our PHP framework. I had a look at how the site is being loaded from a old link that is still in Google and here's what firebug is reporting: GET <google link> 302 Found GET example.com/products/item/127 302 Found GET example.com/products/item/127 301 Moved Permanently GET example.com/product/127/my-jucy-product/ 302 Found So the Google link has a 302, good. But when the old link comes in our framework is returning a 302! It's only afterwards when it finally hits the right part of the framework does it 301, so here's my question: Is the reason our old links have not changed and our Google Ranking has significantly nose dived because Google is seeing a 302 before the 301? At the time I was reluctant to mess with our .htaccess because it had become pretty complicated and I was under some pretty intense time constraints, now I'm wondering whether this was an incorrect disicion and perhaps I should revisit it. Many thanks! Edit Bugger, just signed up to the Webmaster Tools and I'm getting redirect errors all over the place, hundreds of them! I think this is my problem.

  • Spring - How do you set Enum keys in a Map with annotations

    - by al nik
    Hi all, I've an Enum class public enum MyEnum{ ABC; } than my 'Mick' class has this property private Map<MyEnum, OtherObj> myMap; I've this spring xml configuration. <util:map id="myMap"> <entry key="ABC" value-ref="myObj" /> </util:map> <bean id="mick" class="com.x.Mick"> <property name="myMap" ref="myMap" /> </bean> and this is fine. I'd like to replace this xml configuration with Spring annotations. Do you have any idea on how to autowire the map? The problem here is that if I switch from xml config to the @Autowired annotation (on the myMap attribute of the Mick class) Spring is throwing this exception nested exception is org.springframework.beans.FatalBeanException: Key type [class com.MyEnum] of map [java.util.Map] must be assignable to [java.lang.String] Spring is no more able to recognize the string ABC as a MyEnum.ABC object. Any idea? Thanks

  • How to assign .net membership roles to individual database records

    - by mdresser
    I'm developing a system where we want to restrict the availability of information displayed to users based on their roles. e.g. I have a tabled called EventType (ID, EventTypeDescription) which contains the following records: 1, 'Basic Event' 2, 'Intermediate Event' 3, 'Admin Event' What I need to achieve is to filter the records returned based on the username (and hence role) of the logged-in user. e.g if an advanced user is logged in they will see all the event types, if the standard user is logged in they will only see the basic event type etc. Ideally id like to do this in a way which can be easily extended to other tables as necessary. So I'd like to avoid simply adding a 'Roles' field to each table where the data is user context sensitive. One idea I'm thinking of is to create some kind of permissions table like: PermissionsTable ( ID, Aspnet_RoleId, TableName, PrimaryKeyValue ) this has the drawback of using this is obviously having to use the table name to switch which table to join onto. Edit: In the absence of any better suggestions, I'm going to go with the last idea I mentioned, but instead of having a TableName field, I'm going to normalise the TableName out to it's own table as follows: TableNames ( ID, TableName ) UserPermissionsTable ( ID, Aspnet_UserId, TableID, PrimaryKeyValue )

  • applicationWillTerminate Appears to be Inconsistent

    - by Lauren Quantrell
    This one has me batty. In applicationWillTerminate I am doing two things: saving some settings to the app settings plist file and updating any changed data to the SQLite database referenced in the managedObjectContext. Problem is it works sometimes and not others. Same issue in the simulator and on the device. If I hit the home button while the app is running, I can only sometimes get the data to store in the plist and into the CoreData store. It seems that it's both works or neither works, and it makes no difference if I switch the execution order (saveState, managedObjectContext or managedObjectContext, saveState). I can't figure out how this can happen. Any help is greatly appreciated. lq AppDelegate.m @synthesize rootViewController; - (void)applicationWillTerminate:(UIApplication *)application { [rootViewController saveState]; NSError *error; if (managedObjectContext != nil) { if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) { // Handle error exit(-1); // Fail } } } RootViewController.m - (void)saveState { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:self.someInteger forKey:kSomeNumber]; [userDefaults setObject:self.someArray forKey:kSomeArray]; }

  • Ninject InThreadScope Binding

    - by e36M3
    I have a Windows service that contains a file watcher that raises events when a file arrives. When an event is raised I will be using Ninject to create business layer objects that inside of them have a reference to an Entity Framework context which is also injected via Ninject. In my web applications I always used InRequestScope for the context, that way within one request all business layer objects work with the same Entity Framework context. In my current Windows service scenario, would it be sufficient to switch the Entity Framework context binding to a InThreadScope binding? In theory when an event handler in the service triggers it's executed under some thread, then if another file arrives simultaneously it will be executing under a different thread. Therefore both events will not be sharing an Entity Framework context, in essence just like two different http requests on the web. One thing that bothers me is the destruction of these thread scoped objects, when you look at the Ninject wiki: .InThreadScope() - One instance of the type will be created per thread. .InRequestScope() - One instance of the type will be created per web request, and will be destroyed when the request ends. Based on this I understand that InRequestScope objects will be destroyed (garbage collected?) when (or at some point after) the request ends. This says nothing however on how InThreadScope objects are destroyed. To get back to my example, when the file watcher event handler method is completed, the thread goes away (back to the thread pool?) what happens to the InThreadScope-d objects that were injected? EDIT: One thing is clear now, that when using InThreadScope() it will not destroy your object when the handler for the filewatcher exits. I was able to reproduce this by dropping many files in the folder and eventually I got the same thread id which resulted in the same exact Entity Framework context as before, so it's definitely not sufficient for my applications. In this case a file that came in 5 minutes later could be using a stale context that was assigned to the same thread before.

  • Add double tap action (presentModalViewController) to UISCOLLVIEW

    - by R.J.
    I have been wrestling this issue for a while now and cannot seem to get the following "touchesEnded" method to execute within a UISCROLLVIEW. I have read on many of the forums that UISCROLLVIEW will take control of all touch events unless it is subclassed, but I cannot seem to get the code right (still new to the SDK). Basically I have a scrollview made uo with several UIIMAGEVIEW's and currenlty have scrolling with paging (much like the photo app). I have been studying the SCROLLING MADDNESS example without success. All I want to do is anywhere in the UISCROLLVIEW have the user double tap to presentModalViewController back to my info page (i.e.) (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: {// One finger touch UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; if ([touch tapCount] == 2) {InfoButtonViewController *scroll = [[InfoButtonViewController alloc] initWithNibName:nil bundle:nil]; scroll.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:scroll animated:YES]; [scroll release]; } } } } Any code assistance would be greatly appreciated. The UISCROLLVIEW is implemented as follows (let me know if I need to provide additional details). Thank you in advance... MyViewController.h @interface MyViewController : UIViewController { } @end

  • Migration of .NET COM object to 64 bit.

    - by Victor Ronin
    Hi, We have C++ application which uses several COM object. COM object are .NET based (using COM Interop). I need to migrate application to 64 bit. I specifically need C++ application to be 64 bit. I don't want to recompile all of .NET com object to 64 bit and deliver two sets of DLL's (32 bit and 64 bit). I was investigating and found that I can load 32 bit COM Dll's in 32 bit surrogate process using (DllSurrogate in registry). I know how to do that, but it means that all COM objects will become out of process. In the C++ I had the code: CoCreateInstance(CLSID_SomeClass, NULL, CLSCTX_INPROC_SERVER, IID_SomeInterface, (void**)&pobj); It worked fine, but as soon as I switch to CLSCTX_LOCAL_SERVER (and add registry keys for DllSurrogate), it can't find interfaces (error 0x80004002). I checked registry and found out that when .NET COM DLL is registered, it adds ClsID registry keys, but doesn't add Interface and TypeLib registry key. The question is, how to create these registry keys for .NET COM? Regards, Victor

  • Excel COM Add-In dialog interrupts script

    - by usac
    Hi all! I have written an Excel COM Add-In in C++ for automation of Excel with VBA. It contains an own dialog showing some general informations about the Add-In. Now i create a button in Excel that opens the dialog. Leaving the dialog with the escape key leads to an Excel message that the script is being interrupted instead of just closing the dialog. I could suppress the interruption message with: Application.EnableCancelKey = xlDisabled But that seems not to be the solution as the script can not be interrupted any more. Here is an example how i use VBA to open the dialog: Private Sub ShowAboutDialog_Click() Dim oComAddIn As COMAddIn Set oComAddIn = Application.COMAddIns.Item("MyComAddIn.Example") oComAddIn.Connect = True Call oComAddIn.Object.ShowAboutDlg End Sub My guess is that the problem is somewhere in the message handler of the dialog: INT_PTR CALLBACK CAboutDialog::AboutDlg( HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam) { switch(uMsg) { ... case WM_COMMAND: if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL) { // Here, the ESCAPE key should also be trapped? EndDialog(hwndDlg, LOWORD(wParam)); return TRUE; } ... } return FALSE; } The Dialog is created with: DialogBox(g_hModule, MAKEINTRESOURCE(IDD_ABOUT), hWndParent, (DLGPROC)AboutDlg) Thanks a lot!

  • Two-way data binding of controls in a user control inside a FormView

    - by Sandor Drieënhuizen
    I'm trying to perform two-way data binding on the controls in my user control, which is hosted inside a FormView template. FormView: <asp:ObjectDataSource runat="server" ID="ObjectDataSource" TypeName="WebApplication1.Data" SelectMethod="GetItem" UpdateMethod="UpdateItem"> </asp:ObjectDataSource> <asp:FormView runat="server" ID="FormView"> <ItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </ItemTemplate> <EditItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </EditItemTemplate> </asp:FormView> User control: <%@ Control Language="C#" ... %> <asp:TextBox runat="server" ID="TitleTextBox" Text='<%# Bind("Title") %>'> </asp:TextBox> The binding works fine when the FormView is in View mode but when I switch to Edit mode, upon calling UpdateItem on the FormView, the bindings are lost. I know this because the FormView tries to call an update method on the ObjectDataSource that does not have an argument called 'Title'. I tried to solve this by implementing IBindableTemplate to load the controls that are inside my user control, directly into the templates (just like I had entered them declaratively like in the code above). However, when calling UpdateItem in edit mode, the container that gets passed into the ExtractValues method of the template, does not contain the TextBox anymore. It did in view mode! I have found some questions on SO that relate to this problem but they are rather dated and don't provide straight forward answers. How do you think I could solve this problem? It seems to be such a simple requirement but apparently it's more like opening a can of worms...

  • IPhone SDK removal of NSLog causes NSArray to be undeclared !

    - by Maxwell Segal
    I have a working application I'm about to distribute and am tidying up NSLog statements in it. When I remove NSLog from from a "case" statement, the NSArray declared within the "case" statement errors as Expected expression before AND undeclared. Anybody any idea why this may be? This is happening on all case statements in my app where I'm now removing NSLog. An example code sections appears below: switch (chosenScene) { case 0: //NSLog(@"group1"); // the following NSArray errors with "expected expression.."

  • Core Data - Entity Relationships Not Working as expected

    - by slimms
    I have set up my data model in xcode like so EntityA AttA1 AttA2 EntityB AttB1 AttB2 AttB3 I then set up the relationships EntityA Name: rlpToEntityB Destination: EntityB Inverse: rlpToEntityA To Many: Checked EntityB Name: rlpToEntityA Destination: EntityA Inverse: rlpToEntityB To Many: UnChecked i.e. relationship between the two where Each one of EntityA can have many EntityB's It is my understanding that if i fetch a subset of EntityB's I can then retrieve the values for the related EntityA's. I have this working so that i can retrieve the EntityB values using NSManagedObject *objMO = [fetchedResultsController objectAtIndexPath:indexPath]; strValueFromEntityB = [objMO valueForKey:@"AttB1"]; However, if I try to retrieve a related value from EntityA by doing the following strValueFromEntityA = [objMO valueForKey:@"AttA1"]; I get the error "The entity EntityB is not Key value coding-compliant for the key Atta1" Not surprisingly i suppose if i switch things around to fetch from EntityA i cannot access attributes of EntityB So it appears the defined relationshipare being ignored. Can anyone spot what i am doing wrong? I confess im very new to iPhone programming and especially to Core Data so please go easy on me and provide verbose explanations or point me in the direction a specific resource. I have downloaded the apple sample apps (Core Data Books, Top Songs and recipes) but I still can't work this out. Thanks in advance, Nev.

    Using VC71 compiler and get compiler errors, that i don't understand. Here comes the example class A { public: virtual int& myMethod() = 0; virtual const int& myMethod()const = 0; }; class B: public A { public: // generates: error C3241: 'const int &B::myMethod(void)' : this method was not introduced by 'A' virtual const int& A::myMethod() const; virtual int& A::myMethod(); }; when i switch order of both method definitions in B then I see a different compiler error: class B: public A { public: virtual const int& A::myMethod() const; // error C2556: 'const int &B::myMethod(void)' : overloaded function differs only by return type from 'int &B::myMethod(void)' // error C2373: 'B::myMethod' : redefinition; different type modifiers virtual int& A::myMethod(); }; however, if I omit the A:: stuff then i don't get any compiler error: class B: public A { public: virtual int& myMethod(); virtual const int& myMethod() const; }; So, what exactly does A:: in front of my method names and why do i see these diverse compiler errors?

  • Strange behaviour using Drag and Drop in word 2003 automation in headers

    - by Oliver Hanappi
    Hi! I am developing a template based addin for Word 2003 which allows the user to drag and drop elements from a listbox into the word document. Unfortunately I'm getting a really strange behaviour when trying to drop elements in the document's header. Open the template and type something in the header Close the header and insert some content on the page Add a page break. Switch to page layout mode where and set zoom level to "Two Pages" Open the header Slowly Drag and Drop an list item from the list box to the header. See multiple Page Setups dialogs occur which cause Word to crash. Here is my code: // in ThisDocument.cs public MyUserControl _control; public void Init() { _control = new MyUserControl(); ActionsPane.Controls.Add(_control); ActionsPane.Visible = true; } // in MyUserControl.cs public void listBox1_MouseDown(object sender, MouseEventArgs e) { DoDragDrop("something", DragDropEffects.Copy); } Have I done somethinkg wrong with implementing Drag and Drop? Is there a workaround for this strange behaviour? Thanks in advance, Oliver Hanappi

  • PostgreSQL: BYTEA vs OID+Large Object?

    - by mlaverd
    I started an application with Hibernate 3.2 and PostgreSQL 8.4. I have some byte[] fields that were mapped as @Basic (= PG bytea) and others that got mapped as @Lob (=PG Large Object). Why the inconsistency? Because I was a Hibernate noob. Now, those fields are max 4 Kb (but average is 2-3 kb). The PostgreSQL documentation mentioned that the LOs are good when the fields are big, but I didn't see what 'big' meant. I have upgraded to PostgreSQL 9.0 with Hibernate 3.6 and I was stuck to change the annotation to @Type(type="org.hibernate.type.PrimitiveByteArrayBlobType"). This bug has brought forward a potential compatibility issue, and I eventually found out that Large Objects are a pain to deal with, compared to a normal field. So I am thinking of changing all of it to bytea. But I am concerned that bytea fields are encoded in Hex, so there is some overhead in encoding and decoding, and this would hurt the performance. Are there good benchmarks about the performance of both of these? Anybody has made the switch and saw a difference?

  • Sharepoint isn't accepting new Credentials initially when switching users.

    - by Tiziani
    Hi all, I have a standard website (one webapplication and one site collection) with some custom pages and webparts. The issue I'm having is that when I try to switch users, using the "Sign In As a Different User" and entering new credentials (even for another site collection admin account), IE tries the account three times, and then it presents a 401 Access Denied screen. After that, if I erase all the stuff of access denied page from the browser's url, I'm logged as the new account I just had entered and was not accepted. After researching for a while on google, I found a KB ( http://support.microsoft.com/kb/970814 ) that might relate, but just tested here and it didn't work at all. The modified method suggested by the KB is the following: function LoginAsAnother(url, bUseSource) { document.cookie="loginAsDifferentAttemptCount=0"; if (bUseSource=="1") { GoToPage(url); } else { //var ch=url.indexOf("?") =0 ? "&" : "?"; //url+=ch+"Source="+escapeProperly(window.location.href); //STSNavigate(url); document.execCommand("ClearAuthenticationCache"); } } But after making this change, it no longer asks for a new credential. Any ideas?

  • How do I fork a maximum of 5 child processes of the parent at any one time?

    - by bstullkid
    I have the following code, which I'm trying to only allow a maximum of 5 children to run at a time, but I can't figure out how to decrement the child count when a child exits. struct { char *s1; char *s2; } s[] = { {"one", "oneB"}, {"two", "twoB"}, {"three", "thr4eeB"}, {"asdf", "3th43reeB"}, {"asdfasdf", "thr33eeB"}, {"asdfasdfasdf", "thdfdreeB"}, {"af3c3", "thrasdfeeB"}, {"fec33", "threfdeB"}, {NULL, NULL} }; int main(int argc, char *argv[]) { int i, im5, children = 0; int pid = fork(); for (i = 0; s[i].s2; i++) { im5 = 0; switch (pid) { case -1: { printf("Error\n"); exit(255); } case 0: { printf("%s -> %s\n", s[i].s1, s[i].s2); if (i==5) im5 = 1; printf("%d\n", im5); sleep(i); exit(1); } default: { // Here is where I need to sleep the parent until chilren < 5 // so where do i decrement children so that it gets modified in the parent process? while(children > 5) sleep(1); children++; pid = fork(); } } } return 1; }

  • Apache with JBOSS using AJP (mod_jk) giving spikes in thread count.

    - by Beginner
    We used Apache with JBOSS for hosting our Application, but we found some issues related to thread handling of mod_jk. Our website comes under low traffic websites and has maximum 200-300 concurrent users during our website's peak activity time. As the traffic grows (not in terms of concurrent users, but in terms of cumulative requests which came to our server), the server stopped serving requests for long, although it didn't crash but could not serve the request till 20 mins. The JBOSS server console showed that 350 thread were busy on both servers although there was enough free memory say, more than 1-1.5 GB (2 servers for JBOSS were used which were 64 bits, 4 GB RAM allocated for JBOSS) In order to check the problem we were using JBOSS and Apache Web Consoles, and we were seeing that the thread were showing in S state for as long as minutes although our pages take around 4-5 seconds to be served. We took the thread dump and found that the threads were mostly in WAITING state which means that they were waiting indefinitely. These threads were not of our Application Classes but of AJP 8009 port. Could somebody help me in this, as somebody else might also got this issue and solved it somehow. In case any more information is required then let me know. Also is mod_proxy better than using mod_jk, or there are some other problems with mod_proxy which can be fatal for me if I switch to mod__proxy? The versions I used are as follows: Apache 2.0.52 JBOSS: 4.2.2 MOD_JK: 1.2.20 JDK: 1.6 Operating System: RHEL 4 Thanks for the help.

  • Removing a platform from Configuration Manager

    - by demoncodemonkey
    I have a solution containing C# and C++/CLI projects. There are 3 platforms in my solution: Any CPU Win32 Mixed Platforms I never want to "just build the C# ones" or "just build the C++ ones", I always want to build all projects. So the platforms metaphor is meaningless to me, I'll leave it on Mixed Platforms or whatever as long as they all build. Now VS sometimes automatically switches the current platform to Any CPU (I'm not sure when or why). This means that pressing F7 will only try to build the C# projects, which is obviously no good. So I have to switch back to Mixed Platforms and try again. So how to workaround this irritating problem? I have tried 2 ways: In Configuration Manager, remove Any CPU and Win32 platforms. This worked until I added a new project and Visual Studio very kindly added them back in... :/ In Configuration Manager, check all checkboxes for all projects in all configurations in all platforms. This becomes a nightmare to manage with many projects in the solution. Any other ideas?

  • if (i == 2) or if (2 == i) ?

    - by Maroloccio
    I usually use if (i == 2) in preference to if (2 == i) On occasion, I would switch things around when writing xUnit-type tests from scratch so as to follow the assertion convention of "expected" preceding "actual". When adding to existing unit tests, I always follow the style I find. No matter what, I always try to keep things consistent. Today I checked out some code with a lot of "if (2 == i)" and started wondering: which style is more "popular" nowadays? is popularity language-dependent? The latter probably because I am aware of why the "if (2 == i)" became common in the first place (C heritage) and because I see some languages go as far as disallowing assignments within conditions (e.g. Python). I thought about downloading some sources: apt-get source linux-source eclipse openoffice.org expanding them and performing a quick grep: grep --color --include=*.java --include=*.c -ERI \ "if[[:space:]]*\([[:space:]]*[[:digit:]]+[[:space:]]==" . or creating a quick "poll": http://goo.gl/mod/ciMF after a bit of searching and asking around, I am still not sure. So I am asking you: which way to go?
