  - by Andrea Girardi

  Hi guys, I've found this helpful tutorial on web http://blog.rayapps.com/2009/09/14/how-to-install-oracle-database-10g-on-mac-os-x-snow-leopard/ I've followed all steps, but, I've a problem with netca run.

• Jquery Validate Issue

  - by Thomas

  I'm using the Jquery validate plugin to validate a multi-step form like this one: http://jquery.bassistance.de/validate/demo/multipart/ Unfortunately, I can't seem to get it to work at all and there is a total lack of documentation to guide me through implemnetation. I think the accordian part of script is firing correctly because the bottom half of the form is being hidden and a 'next' button has been successfuly inserted. However, the form never validates or delivers an error message and it is impossible to move on to the next step. Check it out here: http://www.loftist.com/?page_id=78

• WPF DataGrid: How to reset column width when applying new ItemsSource

  - by paul

  I am using a DataGrid to display details of an item selected in a ListBox. The DataGrid has 3 columns set to Width="Auto". As different items in the ListBox are selected, the width of the columns in the DataGrid increase as needed in order to display the text. What I want is that the column widths also decrease when the extra width is not needed. An example. Column 1 normally contains a percent value. However, in some cases it contains a long error message which causes column 1 to widen and push columns 2 & 3 off the screen. When I switch to an item containing normal values, I want column 1 to regain its' normal width and for columns 2 & 3 to be visible again. What can I do to force the column widths to take the minimum size?

• user disallowed geolocation - notify user second time

  - by Dror

  When trying to get geolocation on iPhone the first time - I declined. Every other time I want to get the location (before another reload of the page) I get no response (no error and no success): navigator.geolocation.getCurrentPosition( function (location) { ig_location.lat = location.coords.latitude; ig_location.lng = location.coords.longitude; alert('got it!'); }, function(PositionError) { alert('failed!' + PositionError.message); } ); Is there a way to notify the user every time I fail to get the location? (I do not need to use watchPosition...)

• RPC Runtime exception

  - by viswanathan

  Hi I am having an application which requires inter process communication between different processes in different machines. Assume i have 2 processes in different machines which communicate usnig RPC. Everything works fine in the normal case. Now if i remove network and reconnect the same my processes still work however what happens is sometimes an RPC call(which sends a message from one process on one machine to another process on another machine) fails with an error code value of 3765269347, which may not really make any sense. This failure occurs only sometimes and i have no clue as to why this occurs. Anybody knows any reason why this may occur or general network related RPC issues. Thanks in advance.

• WSDL Object model

  - by Swaroop

  I'm using the WSDL object model (WOM) along with XSOM for a project of mine. The WOM gives me a way to drill down and look at messages and the message types which are element declarations. However, I am unable to find a way to parse the simple and complex types. The APIs are tricky. There seems to be some kind of a connection between WOM and XSOM. I'd really appreciate it if you could tell me how I can parse the simple and the complex types in my .wsdl file.

• ASP.NET MVC Class level custom data-annotation and ModelState keys

  - by Neil

  Hi, I have custom class level validation attribute, inheriting from ValidationAttribute, on my model. How come it doesn't register a key in the ModelState when its IsValid is false? I can see the the error message in the ModelState.Values collection, but the ModelState.Keys collection only shows an empty string "". Can I provide a key for it - presumably this is because its not assigned to a property? I wanna be able to use ModelState.Remove in my controller to remove this error upon a certain condition, but I have no Key! Any ideas?

• [PHP] function().function() VS function()function()

  - by kwokwai

  Hi all, I was writing a foreach Loop in PHP5. Here is the script: foreach(range('A','Z') as $char) // line 1 { // line 2 echo strtoupper($char)strtolower($char); // line 3 } // line 4 And I got this error message Parse error: parse error, unexpected T_STRING in testing.php on line 3 I spent almost an hour to figure out I should add a dot between two functions like this: echo strtoupper($char).strtolower($char); So I can't tell the difference between these two lines of codes: echo strtoupper($char).strtolower($char); echo strtoupper($char)strtolower($char);

• IMAP Idle Timeout

  - by Paul

  Lets say I am using IMAP IDLE to monitor changes in a mail folder. The IMAP spec says that IDLE connections should only stay alive for 30 minutes max, but it is recommended that a lower number of minutes is selected - say 20 minutes, then cancel the idle and restart. I am wondering what would happen if the mail contents changed between the idle canceling, and the new idle being created. An email could potentially be missed. Given that RECENT is a bit vague, this could lead to getting a message list before the old idle ends, and a new idle starts. But this is almost the same as polling every 20 minutes, and defeats some of the benefit of idle. Alternatively, a new idle session could be started prior to terminating the expiring one. But in any case, I think this problem has already been solved so here I am asking for recommendations. Thanks, Paul

• How to prevent non-admin user from disabling the Outlook 2007Addin?

  - by kapilg

  As per the MSDN documentation with the Office 2007 system, office Addins are registered under HKCU and not under HKLM. I have an Outlook 2007 addin which is also registered under HKCU. But the problem is that, even non admin users can also disable the addin since it is in HKCU. However with Outlook2003 addin this was not possible because it got registered in HKLM. I also see some of the Outlook 2007 addins that are registered under HKLM like Microsoft VBA for Outlook Addin, Microsoft outlook Mobile service. When a non admin user tries to disable it, outlook displays a pop up message saying that these addins are registered in HKLM and user does not have the permission to disable it. So How can I register my Outlook 2007 addin under HKLM like these?

• Handle "Cannot access a closed resource set"

• F# PowerPack 2.0.0.0 issue: The task ..."…\fslex.exe" is invalid

  - by Roman Kuzmin

  I have upgraded F# PowerPack today to the latest 2.0.0.0 and tried to rebuild the MiniCalc sample from here: http://achrissmith.blogspot.com/2010/04/fslex-and-fsyacc-examples-updated.html If I build it in VS 2010 it fails with the message: C:\Program Files\MSBuild\FSharp\1.0\FSharp.PowerPack.targets(32,3): error MSB6004: The specified task executable location "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\fslex.exe" is invalid. If I build it from the command line by MSBuild it complains about missing C:\Windows\Microsoft.NET\Framework\v4.0.30319\fslex.exe The problem is kind of “fixed” if I copy fslex and fsyacc to that both directories, so after that I can build from the command line and from VS 2010. But it does not look like a right way to solve the problem. What is the right way? EDIT: The same issue is true for the PowerPack sample from sources: May2010\workyard\tests\LexAndYaccMiniProject. Now (after the trick I have done) it is built fine, too.

• HTTP Content-Type in ASP.Net SoapHttpClientProtocol

  - by Daniel Fone

  Hi there, I have a problem with a Web Service Consumer written in ASP.NET. The error message is: System.InvalidOperationException: Client found response content type of 'application/xml; charset=utf-8', but expected 'text/xml'. The client is based on System.Web.Services.Protocols.SoapHttpClientProtocol. We can't change the Content-Type given by the provider, this has to be 'application/xml; charset=utf-8'. Is there any way to change what Content-Type the SoapHttpClientProtocol expects? Unfortunately, we are probably limited to .NET 1.1. Thanks! Update: We found a way to change the Content-Type sent by the provider, and this solved the problem. I'd still be curious to know how to change the expectations of the consumer though.

• Facebook graph API - OAuth Token

  - by Simon R

  I'm trying to retrieve data using the new graph API, however the token I'm retriving from OAuth doesn't appear to be working. The call I'm making is as follows; $token = file_get_contents('https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=<app_id>&client_secret=<app secret>'); This returns a token with a string length of 41. To give you an example of what is returned I have provided below a sample (converted all numbers to 0, all capital letters to 'A' and small case letters to 'a' access_token=000000000000|AaaAaaAaaAAaAaaaaAaaAa0aaAA. I take this access token and attach it to the call request for data, it doesn't appear to be the correct token as it returns nothing. I make the data call as follows; file_get_contents('https://graph.facebook.com/<my_page's_id>/statuses?access_token=000000000000|AaaAaaAaaAAaAaaaaAaaAa0aaAA.') When I manually retrieve this page directly through the browser I get an 500/Internal Server Error Message. Any assistance would be grately appreciated.

• C# How to add an entry to LDAP with multiple object classes

  - by Jarmo

  I'm trying to create a new user record into OpenLDAP with object classes person and uidObject. The problem seems to be that with System.DirectoryServices.DirectoryEntry I've found only a way to add a new entry with one object class, but not a way to add multiple object classes. This C# code DirectoryEntry nRoot = new DirectoryEntry(path); nRoot.AuthenticationType = AuthenticationTypes.None; nRoot.Username = username; nRoot.Password = pwd; try { DirectoryEntry newUser = nRoot.Children.Add("CN=" + "test", "person"); newUser.Properties["cn"].Add("test"); newUser.Properties["sn"].Add("test"); newUser.Properties["objectClass"].Add("uidObject"); // this doesnt't make a difference newUser.Properties["uid"].Add("testlogin"); // this causes trouble newUser.CommitChanges(); } catch (COMException ex) { Console.WriteLine(ex.ErrorCode + "\t" + ex.Message); } ...results in error: -2147016684 The requested operation did not satisfy one or more constraints associated with the class of the object. (Exception from HRESULT: 0x80072014)

• problem with jsf / icefaces depended form fields and validation

  - by hubertg

  Hi, I have a form with 3 fields (simplyfied example). The first one is a checkbox. <ice:selectBooleanCheckBox value=#{backingBean.bean.visible} ID=checkbox1 partialSubmit=true> The second one is a <ice:inputText ID=text1> The third one is also a <ice:inputText ID=text2> text1 should only be visible when checkbox1 is checked. text2 is a required field. So my first approach with just using #{backingBean.bean.visible} failed because text2 has is required and a validation message appeared (after the checkbox was clicked) when the text2 field is empty. Because of ths valdation error the form was never completely submitted such that the visible property is set (update model phase was never reached). So my question: how can I make sure text1 is only visible when checkbox1 is clicked? Thanks.

• How to catch all exceptions in Flex?

  - by Yaba

  When I run a Flex application in the debug flash player I get an exception pop up as soon as something unexpected happened. However when a customer uses the application he does not use the debug flash player. In this case he does not get an exception pop up, but he UI is not working. So for supportability reasons, I would like to catch any exception that can happen anywhere in the Flex UI and present an error message in a Flex internal popup. By using Java I would just encapsulate the whole UI code in a try/catch block, but with MXML applications in Flex I do not know, where I could perform such a general try/catch.

• How to release MPMoviePlayerController?

  - by 4thSpace

  I have a couple of views that access the movie player. I've put the following code in a method in AppDelegate for these views. They send in the filename to play. The code works fine but I know a release is required somewhere. If I add the last line as a release or autorelease, the app will crash once the user presses done on the movieplayer. MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:moviePath]]; moviePlayer.movieControlMode = MPMovieControlModeDefault; [moviePlayer play]; //[moviePlayer release]; I get this error: objc[51051]: FREED(id): message videoViewController sent to freed object=0x1069b30 Program received signal: “EXC_BAD_INSTRUCTION”. How should I be releasing the player?
