  • In Xcode, the main controller is hopelessly misconfigured. What are the steps I can take to fix all

    - by MikeN
    Somehow the main .xib file for my iphone project got deleted. I created a replacement .xib file, but the properties are not setup correctly for the MainWindow to load this one. I don't understand and am hopelessly confused about any of the properties and which ones may or may not be sent. What are the X properties that all need to be set to have this work correctly? I've checked all of these, but there appear to be others: 1) The app delegate for the project is set to the new ControllerUI class. 2) The MainWindow.xib shows the correct .xib file as being loaded from (it has a link in its UI to the .xib file that should be loaded on project run. There appear to be other settings that have to be changed and I can't find them. Is there a way in XCode to recreate the MainWindow.xib file? Should I just create a new project and move all of the other files into it?

  • Preventing objects from being linked if they are not needed?

    - by Massif
    I have an ARM project that I'm building with make. I'm creating the list of object files to link based on the names of all of the .c and .cpp files in my source directory. However, I would like to exclude objects from being linked if they are never used. Will the linker exclude these objects from the .elf file automatically even if I include them in the list of objects to link? If not, is there a way to generate a list of only the objects that need to be linked?

  • ASPX FormsAuthentication.RedirectFromLoginPage function is not working anymore

    - by Mike Webb
    Here is my issue. I have an ASPX web site and I have code in there to redirect from the login page with the call to "FormsAuthentication.RedirectFromLoginPage(username, false);" This sends the user from the root website folder to 'website/Admin/'. I have a 'default.aspx' page in 'website/Admin/' and the call to redirect works on a previous version of the website we have running currently, but the one that I am updating on a separate test server is not working. It gives me the error "Directory Listing Denied. This Virtual Directory does not allow contents to be listed." I have this in the config file: <authorization> <allow users="*" /> </authorization> under the "authentication" option and... <location path="Admin"> <system.web> <authorization> <deny users="?" /> </authorization> </system.web> </location> for the location of Admin. Also, there is no difference in the code between the web.config, Login.aspx, or the default.aspx files on the current server and the one on the test server, so I am confused as to why the redirect will not work on both. It even works in the Visual Studio server environment, for which the code is also identical. Any suggestions and help is appreciated.

  • Using boost.python to import a method with opencv calls but failing due to symbols not being found a

    - by nmz787
    So I don't have the code right now, as I am not home... but i used the boost library for python in C++ to allow python to access a function called something like loadImageIntoMainWindow(string filepath) in the C++ source code the method calls opencv methods that are imported at the top of the file, I included opencv in my Jamroot file, and also found a way to compile and link manually on the command line... in either case when I run my python file it complains that the symbols aren't found for the first function call to an opencv method... I will update as soon as I get home with the C++, the command line compilation lines, the Jamroot, and the python files

  • Problem Activating Sharepoint Timer Job

    - by Ben Robinson
    I have created a very simple sharepoint timer job. All i want it to do is iterate through a list and update each list item so that it triggers an existing workflow that works fine. In other words all i am trying to do is work around the limitation that workflows cannot be triggered on a scheduled basis. I have written a class that inherits from SPJobDefinition that does the work and i have a class that inherits from SPFeatureReceiver to install and activate it. I have created the feature using SPVisualdev that my coleagues have used in the past for other SP development. My Job class is below: public class DriverSafetyCheckTrigger : SPJobDefinition { private string pi_SiteUrl; public DriverSafetyCheckTrigger(string SiteURL, SPWebApplication WebApp):base("DriverSafetyCheckTrigger",WebApp,null, SPJobLockType.Job) { this.Title = "DriverSafetyCheckTrigger"; pi_SiteUrl = SiteURL; } public override void Execute(Guid targetInstanceId) { using (SPSite siteCollection = new SPSite(pi_SiteUrl)) { using (SPWeb site = siteCollection.RootWeb) { SPList taskList = site.Lists["Driver Safety Check"]; foreach(SPListItem item in taskList.Items) { item.Update(); } } } } } And the only thing in the feature reciever class is that i have overridden the FeatureActivated method below: public override void FeatureActivated(SPFeatureReceiverProperties Properties) { SPSite site = Properties.Feature.Parent as SPSite; // Make sure the job isn't already registered. foreach (SPJobDefinition job in site.WebApplication.JobDefinitions) { if (job.Name == "DriverSafetyCheckTrigger") job.Delete(); } // Install the job. DriverSafetyCheckTrigger oDriverSafetyCheckTrigger = new DriverSafetyCheckTrigger(site.Url, site.WebApplication); SPDailySchedule oSchedule = new SPDailySchedule(); oSchedule.BeginHour = 1; oDriverSafetyCheckTrigger.Schedule = oSchedule; oDriverSafetyCheckTrigger.Update(); } The problem i have is that when i try to activate the feature it throws a NullReferenceException on the line oDriverSafetyCheckTrigger.Update(). I am not sure what is null in this case, the example i have followed for this is this tutorial. I am not sure what I am doing wrong.

  • jQuery: Execute function after all ajax .load() requests are finished

    - by Mike
    I have a page that has a tab set. Each of the tabs is loaded by the jQuery .load() function. I want to display a loading animation that disappears when all of the ajax requests are finished. However, document.ready() has only provided me with limited success. How can I ensure that all ajax requests are completed before executing the code to hide the loading animation? Thanks!

  • Trigger Code on a table in my ERP Database

    - by David Stein
    My ERP Vendor has the following trigger on a table: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TRIGGER [dbo].[SOItem_DeleteCheck] ON [dbo].[soitem] FOR DELETE AS BEGIN DECLARE @RecCnt int, @LogInfo varchar(256) SET @RecCnt = (SELECT COUNT(*) FROM deleted) IF @RecCnt > 150 BEGIN RAISERROR (54010, 18, 1, 'SOItem') WITH LOG ROLLBACK TRANSACTION END SET @LogInfo = 'Deleting ' + LTRIM(STR(@RecCnt)) + ' Rows From SOItem' EXEC LogDeletes @LogInfo END GO This seems very inefficient to me. Doesn't select count(*) take longer than Count(specific field)?

  • Oracle JDBC connection exception in Solaris but not Windows?

    - by lupefiasco
    I have some Java code that connects to an Oracle database using DriverManager.getConnection(). It works just fine on my Windows XP machine. However, when running the same code on a Solaris machine, I get the following exception. Both machines can reach the database machine on the network. I have included the Oracle trace logs.

Any ideas on why the behavior is different in the different environments?

  • Highlight a word with jQuery

    - by nickf
    I basically need to highlight a particular word in a block of text. For example, pretend I wanted to highlight the word "dolor" in this text: <p> Lorem ipsum dolor sit amet, consectetuer adipiscing elit. </p> <p> Quisque bibendum sem ut lacus. Integer dolor ullamcorper libero. Aliquam rhoncus eros at augue. Suspendisse vitae mauris. </p> How do I convert the above to something like this: <p> Lorem ipsum <span class="myClass">dolor</span> sit amet, consectetuer adipiscing elit. </p> <p> Quisque bibendum sem ut lacus. Integer <span class="myClass">dolor</span> ullamcorper libero. Aliquam rhoncus eros at augue. Suspendisse vitae mauris. </p> Is this possible with jQuery? Edit: As Sebastian pointed out, this is quite possible without jQuery - but I was hoping there might be a special method of jQuery which would let you do selectors on the text itself. I'm already using jQuery heavily on this site, so keeping everything wrapped up in jQuery would make things perhaps a bit more tidy.

  • SQL Server cluster performance baseline

    - by Dwight T
    Currently I'm tasked with getting a good performance baseline on a SQL 2005 cluster. The main db on the server is for Sharepoint, but I would like to add other dbs on the cluster. I do have access to Quest's Performance Analysis tool to help. What are key factors to look at to see if the cluster can handle additional dbs? Do you look at different performance indicators for a cluster vs a stand alone sql server? One db will be a low usage transactional db and a read only db that is used for sales data. Thanks Dwight

  • Good ways to restart all the computers in a remote cluster?

    - by vgm64
    I have a cluster that I manage and from time to time I get emails from each node (and head node) begging to be restarted after an automatic upgrade. Currently, my best solution so far is a shell script like: $> cat cluster_reboot.sh ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot I end up just typing the root password six times, but it works, I guess. Is there a better way? Can I force the head node to reboot the computers for me?

  • A Firefox "master password" feature that's friendly to guest users?

    - by Josh
    I use the "master password" feature of Firefox and like it for a number of reasons. It does have it's drawbacks, though: anytime I hand my laptop over to my girlfriend so she can check her email on it, she's continually confronted with the prompt to enter my master password. I have since disabled the feature and am back to square one. Is there an addon or tweak that will help?

  • Is it possible to manipulate a request before IIS assigns that request to a specific site?

    - by Deane
    Is it possible to manipulate an inbound request at the IIS level, before it even gets assigned to site on the server? Essentially, I want to rewrite this -- www.somegenericdomain.com?site=someotherdomain To this -- www.someotherdomain.com And I need to do this before IIS picks which site the request belongs to, so I need to change the host header prior to this point. Possible, or crazy? We're running IIS7.

  • How do I reliably get the size of my iPhone view taking rotations into consideration?

    - by Sebastian Celis
    My application uses a UITabBarController, multiple UINavigationControllers, and supports autorotation. In order to properly layout the subviews within each UIViewController's main view, I really need to know the size available to the UIViewContoller. I need this size to take the UINavigationBar, the UITabBar, and the status bar all into account, and thus only return the size available to the content view. I thought for sure I could use the following from within the UIViewController's code: CGRect viewControllerBounds = [[self view] bounds]; However, there are a couple of issues with this approach: The first time the view is loaded, viewControllerBounds reports the view as being 320 pixels wide by 460 pixels tall. This is wrong. With a status bar and a navigation bar showing, the height should only be 416 pixels. However, if I rotate the simulator to landscape and then rotate back, the height of viewControllerBounds changes to 416. If I rotate the first view in the navigation controller to landscape mode and then push another view controller onto the stack, viewControllerBounds for the new view reports a width of 300 pixels and a height of 480 pixels. So the view's bounds didn't even take the rotation into account. Is there a better way to do this? I really don't want to have to start hardcoding the widths and heights of all the various UI elements the iPhone OS provides. I have tried setting the autoresizing mask of the UIViewController's view, but that doesn't seem to change anything. The views definitely seem to be displaying properly. When I set a background color that view looks like it takes up all of the space available to it. Any pointers would be greatly appreciated.

  • ProtectedData.Unprotect() after Impersonate()

    - by Andrey
    The following code doesn't work: IntPtr token = Win32Dll.LogonUser(“user1”, “mydomain”, “password1”); WindowsIdentity id = new WindowsIdentity(token); WindowsImpersonationContext ic = id.Impersonate(); byte[] unprotectedBytes = ProtectedData.Unprotect(passwordBytes, null, DataProtectionScope.CurrentUser); password = Encoding.Unicode.GetString(unprotectedBytes); ic.Undo(); The password is not decrypted. MSDN said "If you use this method during impersonation, you may receive the following error: "Key not valid for use in specified state." This error can be prevented by loading the profile of the user you want to impersonate, before calling the method." I would be very grateful for the help!

  • Create Text File Without BOM

    - by balexandre
    Hi guys, I tried this aproach without any success the code I'm using: // File name String filename = String.Format("{0:ddMMyyHHmm}", dtFileCreated); String filePath = Path.Combine(Server.MapPath("App_Data"), filename + ".txt"); // Process ProcessPBS pbs = new ProcessPBS(); pbs.CreatePBSInfoFile(pbslist, Convert.ToInt64(filename)); // Save file Encoding utf8WithoutBom = new UTF8Encoding(true); TextWriter tw = new StreamWriter(filePath, false, utf8WithoutBom); foreach (string s in pbs.GeneratedFile.ToArray()) tw.WriteLine(s); tw.Close(); // Push Generated File into Client Response.Clear(); Response.ContentType = "application/vnd.text"; Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + ".txt"); Response.TransmitFile(filePath); Response.End(); the result: It's writing the BOM no matter what, and special chars (like Æ Ø Å) are not correct :-/ I'm stuck! I can't create a file using UTF-8 as Encoding and 8859-1 as CharSet :-( Anyone can help me find the light in the tunnel? All help is greatly appreciated, thank you!

  • JavaScript: using constructor without operator 'new'

    - by GetFree
    Please help me to understand why the following code works: <script> var re = RegExp('\\ba\\b') ; alert(re.test('a')) ; alert(re.test('ab')) ; </script> In the first line there is no new operator. As far as I know, a contructor in JavaScript is a function that initialize objects created by the operator new and they are not meant to return anything.

  • Trouble Shoot JavaScript Function in IE

    - by CreativeNotice
    So this function works fine in geko and webkit browsers, but not IE7. I've busted my brain trying to spot the issue. Anything stick out for you? Basic premise is you pass in a data object (in this case a response from jQuery's $.getJSON) we check for a response code, set the notification's class, append a layer and show it to the user. Then reverse the process after a time limit. function userNotice(data){ // change class based on error code returned var myClass = ''; if(data.code == 200){ myClass='success'; } else if(data.code == 400){ myClass='error'; } else{ myClass='notice'; } // create message html, add to DOM, FadeIn var myNotice = '<div id="notice" class="ajaxMsg '+myClass+'">'+data.msg+'</div>'; $("body").append(myNotice); $("#notice").fadeIn('fast'); // fadeout and remove from DOM after delay var t = setTimeout(function(){ $("#notice").fadeOut('slow',function(){ $(this).remove(); }); },5000); }
