  • how to close popup using javascript with xml formatting

    - by Michael Robinson
    I bought this program that created a pretty nice imageuploader flash script however I can't get the Javascript function close window to close the popup and redirect the original page. here is the XML piece that defines the url's: <urls urlToUpload="upload.php?" urlOnUploadSuccess="http://www.home.com/purchase.html" urlOnUploadFail="http://www.home.com/tryagain.html" urlUpdateFlashPlayer="http://www.home.com/flashalternative.html" jsFunctionNameOnUpload=""/> This last line calls a javascript function on upload. The problem is I don't know what to call and where to put it. Here is the HTML file that is the popup: <HEAD> <title>Baublet Uploader</title> <script type="text/javascript" src="swfobject.js"></script> </HEAD> <BODY> <!-- Q-ImageUploader www.quadroland.com --> <div id="QImageUploader"> Flash Player stuff here </div> <script type="text/javascript"> // <![CDATA[ var so = new SWFObject("q_image_uploader.swf", "imageuploader", "650", "430", "9", "#FFFFFF"); so.addParam("scale", "noscale"); so.addParam("salign", "TL"); so.addVariable("AdditionalStringVariable","pass additional data here"); so.write("QImageUploader"); // ]]> </script> I found this Closing script I thought might work: <script language="javascript"> function close_window(page) { window.opener.location.href=page setTimeout(function(){window.close()},10); } </script> Does this go into the Popup HTML page above or would it be a separate close.js file in the root? Thanks, I'm really confused.

  • jQuery.ajax success callback function not executed

    - by Frank Michael Kraft
    I have a JavaScript Ajax call (jQuery.ajax), that does not execute the success callback function. $.ajax({ url: target, contentType: 'application/json; charset=utf-8', type: 'POST', // type: 'GET', dataType: 'jsonp', error: function (xhr, status) { alert(status); }, success: function (result) { alert("Callback done!"); // grid.dataBind(result.results); // grid.dataBind(result); } }); I see in firebug, that the request is posted and the correct result in terms of the json is returned as expected. What is wrong?

  • C# cast Foo<Bar> to Foo<object>

    - by Michael
    Hi, does anyone know if it is possible to cast a generic type with a certain type parameter (e.g. Bar) to the same generic type with the type parameter being a base type of Bar (such as object in my case). And, if it is possible, how would it be done? What I want to do is have a collection of Foo but be able to add Foos with more specific type arguments. Thanks

  • iPhone SDK UI element preview

    - by Michael
    Looking for some catalog/gallery(not UICatalog, just images), where I can see preview of each UI element in iPhone SDK, along with corresponding class name(eg datetime picker, calendar, the black switch bar on bottom). This will give me rough idea on which UI elements I can use in my app and go read about corresponding class.

  • Why is Perl commonly used for writing CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

  • Is Annotation in Javascript? If not, how to switch between debug/productive modes in declarative way

    - by Michael Mao
    Hi all: This is but a curious question. I cannot find any useful links from Google so it might be better to ask the gurus here. The point is: is there a way to make "annotation" in javascript source code so that all code snippets for testing purpose can be 'filtered out' when project is deployed from test field into the real environment? I know in Java, C# or some other languages, you can assign an annotation just above the function name, such as : // it is good to remove the annoying warning messages @SuppressWarnings("unchecked") public class Tester extends TestingPackage { ... } Basically I've got a lot of testing code that prints out something into FireBug console. I don't wanna manually "comment out" them because the guy that is going to maintain the code might not be aware of all the testing functions, so he/she might just miss one function and the whole thing can be brought down to its knees. One other thing, we might use a minimizer to "shrink" the source code into "human unreadable" code and boost up performance (just like jQuery.min), so trying to match testing section out of the mess is not possible for plain human eyes in the future. Any suggestion is much appreciated.

  • File version maintainence via PHP FTP?

    - by Michael
    Currently I'm working on a "plugin" that will be installed on many different sites and I was wondering on the best way for me to maintain the file version of this "plugin". Here's what I was thinking. Have a "master copy" of the plugin on a server, then connect via FTP to the target sites and upload the copy to their site overwriting whatever files they may have. I was wondering the best way to go about this. The "plugin" will have many different folders and files so transferring one file at a time will be too tedious. Is there a way to copy an entire folder over at a time? Or even better, is there a way to recurse through the folders and checking for file difference before uploading the new file? This is to make sure we are uploading a new file and not just the same one.

  • Not able to capture Enter key in WinForms text box

    - by Michael Hermes
    When the user is entering a number into a text box, I would like them to be able to press Enter and simulate pressing an Update button elsewhere on the form. I have looked this up several places online, and this seems to be the code I want, but it's not working. When data has been put in the text box and Enter is pressed, all I get is a ding. What am I doing wrong? (Visual Studio 2008) private void tbxMod_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { btnMod.PerformClick(); } }

  • Need help in resolving a compiler error: error: invalid conversion from ‘int’ to ‘GIOCondition’

    - by michael
    I have a simple cpp file which uses GIO. I have stripped out everything to show my compile error: Here is the error I get: My.cpp:16: error: invalid conversion from ‘int’ to ‘GIOCondition’ make[2]: *** [My.o] Error 1 Here is the complete file: #include <glib.h> static gboolean read_socket (GIOChannel *gio, GIOCondition condition, gpointer data) { return false; } void createGIOChannel() { GIOChannel* gioChannel = g_io_channel_unix_new(0); // the following is the line causing the error: g_io_add_watch(gioChannel, G_IO_IN|G_IO_HUP, read_socket, NULL); } I have seen other example using gio, and I am doing the same thing in term of calling G_IO_IN|G_IO_HUP. And the documentation http://www.gtk.org/api/2.6/glib/glib-IO-Channels.html, said I only need to include , which I did. Can you please tell me how to resolve my error? One thing I can think of is I am doing this in a cpp file. But g_io_add_watch is a c function? Thank you for any help. I have spent hours on this but did not get anywhere.

  • How do I persist form data across an "access denied" page in Drupal?

    - by Michael T. Smith
    We're building a small sub-site that, on the front page, has a one input box form that users can submit. From there, they're taken to a page with a few more associated form fields (add more details, tag it, etc.) with the first main form field already filled in. This works splendidly, thus far. The problem comes for users that are not logged in. When they submit that first form, they're taken to a (LoginToboggan based) login page that allows them to login. After they login, they redirect to the second form page, but the first main form field isn't filled in -- in other words, the form data didn't persist. How can we store that data and have it persist across the access denied page?

  • Possible uncommitted transactions causing "System.Data.SqlClient.SqlException: Timeout expired" erro

    - by Michael
    My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read comments about increasing the timeout period but I've also read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application. I'll provide the code I'm working with and there is an IF statement in there that I was a little iffy about but it seemed like a reasonable thing to do. I'll just go over what's going on here, there is a list of objects to update or add into the database. New objects created in the application are given an ID of 0 while existing objects have their own ID's generated from the DB. If the user chooses to delete some objects, their IDs are stored in a separate list of Integers. Once the user is ready to save their changes, the two lists are passed into this method. By use of the IF statement, objects with ID of 0 are added (using the Add stored procedure) and those objects with non-zero IDs are updated (using the Update stored procedure). After all this, a FOR loop goes through all the integers in the "removal" list and uses the Delete stored procedure to remove them. A transaction is used for all this. Public Shared Sub UpdateSomethings(ByVal SomethingList As List(Of Something), ByVal RemovalList As List(Of Integer)) Using DBConnection As New SqlConnection(conn) DBConnection.Open() Dim MyTransaction As SqlTransaction MyTransaction = DBConnection.BeginTransaction() Try For Each SomethingItem As Something In SomethingList Using MyCommand As New SqlCommand() MyCommand.Connection = DBConnection If SomethingItem.ID > 0 Then MyCommand.CommandText = "UpdateSomething" Else MyCommand.CommandText = "AddSomething" End If MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters If MyCommand.CommandText = "UpdateSomething" Then .Add("@id", SqlDbType.Int).Value = SomethingItem.ID End If .Add("@stuff", SqlDbType.Varchar).Value = SomethingItem.Stuff End With MyCommand.ExecuteNonQuery() End Using Next For Each ID As Integer In RemovalList Using MyCommand As New SqlCommand("DeleteSomething", DBConnection) MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters .Add("@id", SqlDbType.Int).Value = ID End With MyCommand.ExecuteNonQuery() End Using Next MyTransaction.Commit() Catch ex As Exception MyTransaction.Rollback() 'Exception handling goes here End Try End Using End Sub There are three stored procedures used here as well as some looping so I can see how something can be holding everything up if the list is large enough. Other users can log in to the system at the same time just fine though. I'm using Visual Studio 2008 to debug and am using SQL Server 2000 for the DB.

  • How to invalidate cache when benchmarking?

    - by Michael Buen
    I have this code, that when swapping the order of UsingAs and UsingCast, their performance also swaps. using System; using System.Diagnostics; using System.Linq; using System.IO; class Test { const int Size = 30000000; static void Main() { object[] values = new MemoryStream[Size]; UsingAs(values); UsingCast(values); Console.ReadLine(); } static void UsingCast(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is MemoryStream) { var m = (MemoryStream)o; sum += (int)m.Length; } } sw.Stop(); Console.WriteLine("Cast: {0} : {1}", sum, (long)sw.ElapsedMilliseconds); } static void UsingAs(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is MemoryStream) { var m = o as MemoryStream; sum += (int)m.Length; } } sw.Stop(); Console.WriteLine("As: {0} : {1}", sum, (long)sw.ElapsedMilliseconds); } } Outputs: As: 0 : 322 Cast: 0 : 281 When doing this... UsingCast(values); UsingAs(values); ...Results to this: Cast: 0 : 322 As: 0 : 281 When doing just this... UsingAs(values); ...Results to this: As: 0 : 322 When doing just this: UsingCast(values); ...Results to this: Cast: 0 : 322 Aside from running them independently, how to invalidate the cache so the second code being benchmarked won't receive the cached memory of first code? Benchmarking aside, just loved the fact that modern processors do this caching magic :-)

  • When I make a database change, how do I know what needs to be removed and readded to the LinqToSql O

    - by Michael Maddox
    For example, I alter a column in a table to be not null from null. I need to then delete and readd the table. That part is pretty clear. What about views, functions, and stored procedures that access the table, especially that column in the table? I've tried running diffs against the files generated by SQLMetal with some limited success, but even with that it's fairly unclear. I know there is at least one commercial tool out there that claims to address this problem, but I am looking for something free. How are people dealing with this issue?

  • iCloud + Storage of media in iPhone Documents folder

    - by Michael Morrison
    I, like many developers, got an email from Apple recently that stated we should move our data from the documents directory into another folder to permit more streamlined backup to iCloud. In recent testing it appears that [your app] stores a fair amount of data in its Documents folder. Since iCloud backups are performed daily over Wi-Fi for each user's iOS device, it's important to ensure the best possible user experience by minimizing the amount of data being stored by your app. Marco Arment, of instapaper fame, has a good take on the issue, which is that the recommended location for storing downloadable files is in /Library/Caches. However, the problem is that both /tmp and /Caches can be 'cleaned' anytime the OS decides that the device is running low on storage. If your app is cleaned then the data downloaded by your app and stored by your user is gone. Naturally, the user will blame you and not Apple. What to do?

  • How to call a wpf singleton service within a wpf singleton service without hanging?

    - by Michael Hedgpeth
    I have two services, one that calls another. Both are marked as singletons as follows: [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)] public class Service : IService And I set these up with a ServiceHost as follows: ServiceHost serviceHost = new ServiceHost(singletonElement); serviceHost.Open(); When the parent service tries to call the child service on the same machine, the parent service hangs, waiting for the child service. I'm already considering moving away from the singleton model, but is there anything wrong with my approach? Is there an explanation for this behavior and a way out of it?

  • Very Intermittent Orientation on Device & Simulator

    - by Michael Waterfall
    I've noticed that I'm getting very intermittent orientation on my device & the simulator. I have a modal view controller that I present, and that is the only thing in my app which supports rotation. If I launch the app in portrait without moving the device, open the modal VC and then rotate the device, it usually works. However sometimes if I open the app holding the device in landscape, then rotate to portrait, launch the VC and then rotate the device, no rotation occurs. It seems very intermittent. Sometimes if I launch the app in portrait mode and then open the VC and rotate the device, nothing happens, and until I quit and relaunch it no orientation occurs in the app. It's strange because 50% of the time it works! Whenever I launch it through Xcode and set breakpoints in shouldAutorotateToInterfaceOrientation it always works! Anyone ever had this or know what's going on?

  • PHP get "Application Root" in Xampp on Windows correctly

    - by Michael Mao
    Hi all: I found this thread on StackOverflow about how to get the "Application Root" from inside my web app. However, most of the approaches suggested in that thread can hardly be applied to my Xampp on Windows. Say, I've got a "common.php" which stays inside my web app's app directory: / /app/common.php /protected/index.php In my common.php, what I've got is like this: define('DOCROOT', $_SERVER['DOCUMENT_ROOT']); define('ABSPATH', dirname(__FILE__)); define('COMMONSCRIPT', $_SERVER['PHP_SELF']); After I required the common.php inside the /protected/index.php, I found this: C:/xampp/htdocs //<== echo DOCROOT; C:\xampp\htdocs\comic\app //<== echo ABSPATH /comic/protected/index.php //<== echo COMMONSCRIPT So the most troublesome part is the path delimiters are not universal, plus, it seems all superglobals from the $_SERVER[] asso array, such as $_SERVER['PHP_SELF'], are relative to the "caller" script, not the "callee" script. It seems that I can only rely on dirname(__FILE__) to make sure this always returns an absolute path to the common.php file. I can certainly parse the returning values from DOCROOT and ABSPATH and then calculate the correct "application root". For instance, I can compare the parts after htdocs and substitute all backslashes with slashes to get a unix-like path I wonder is this the right way to handle this? What if I deploy my web app on a LAMP environment? would this environment-dependent approach bomb me out? I have used some PHP frameworks such as CakePHP and CodeIgniter, to be frank, They just work on either LAMP or WAMP, but I am not sure how they approached such a elegant solution. Many thanks in advance for all the hints and suggestions.

  • Blittable Value Types

    - by Michael Covelli
    Here is a list of blittable types. It contains Int32 and Int64. But I don't see just plain "int" on the list. How does C# treat the plain "int" type? Does it just get replaced with Int32 or Int64 depending on the system? Or is there a subtle difference? Will using "int" ever cause a performance hit for marshalling?

  • Can't access CodeBase from a dynamically generated assembly.

    I'm trying to create an assembly dynamically in .Net. I can't seem to figure out how to get the CodeBase property to return a value, however. Here's an example: var assemblyName = new AssemblyName { Name = "Whatever", CodeBase = Directory.GetCurrentDirectory() }; var assemblyBuilder = AppDomain.CurrentDomain .DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave); var moduleBuilder = assemblyBuilder.DefineDynamicModule("WhateverModule", "Whatever.dll"); var typeBuilder = moduleBuilder.DefineType("WhateverType", TypeAttributes.Public); var type = typeBuilder.CreateType(); assemblyBuilder.Save("Whatever.dll"); var codeBase = type.Assembly.CodeBase; // throws the below exception System.NotSupportedException was unhandled Message=The invoked member is not supported in a dynamic assembly.

  • Detecting death of spawned process using Window CRT

    - by Michael Tiller
    Executive summary: I need a way to determine whether a Windows process I've spawned via _spawnl and am communicating with using FDs from _pipe has died. Details: I'm using the low-level CRT function in Windows (_eof, _read) to communicate with a process that was spawned via a call to _spawnl (with the P_NOWAIT) flag. I'm using _pipe to create file descriptors to communicate with this spawned process and passing those descriptors (the FD #) to it on the command line. It is worth mentioning that I don't control the spawned process. It's a black box to me. It turns out that the process we are spawning occasionally crashes. I'm trying to make my code robust to this by detecting the crash. Unfortunately, I can't see a way to do this. It seems reasonable to me to expect that a call to _eof or _read on one of those descriptors would return an error status (-1) if the process had died. Unfortunately, that isn't the case. It appears that the descriptors have a life of their own independent of the spawned process. So even though the process on the other end is dead, I get no error status on the file descriptor I'm using to communicate with it. I've got the PID for the nested process (returned from the _spanwnl call) but I don't see anything I can do with that. My code works really well except for one thing. I can't detect whether the spawned process is simply busy computing me an answer or has died. If I can use the information from _pipe and _spawnl to determine if the spawned process is dead, I'll be golden. Suggestions very welcome. Thanks in advance. UPDATE: I found a fairly simple solution and added it as the selected answer.

  • Should i use a trigger or Behaviors for this?

    - by Michael
    I have an abstract object called Applicant and two different types of objects that inherit from Applicant called Business and Individual. So I have three classes that look like this: public abstract class Applicant { ... } public class Individual : Applicant { ... } public class Business : Applicant { ... } Now in the DataGrid I want to show all the details of Applicant object. When you choose a row I want to show details of either the business or individual as a internal grid. Something like this <DataGrid> <DataGrid.Columns> <!--Show different columns --> </DataGrid.Columns> <DataGrid.RowDetailsTemplate> <!--Show if Individual --> <DataGrid> <DataGrid.Columns> <DataGridTextColumn Header="First Name" ... /> <DataGridTextColumn Header="Last Name" ... /> </DataGrid.Columns> </DataGrid> <!--Show if business --> <DataGrid> <DataGrid.Columns> <DataGridTextColumn Header="Business Name" ... /> <DataGridTextColumn Header="Tax id" ... /> </DataGrid.Columns> </DataGrid> </DataGrid.RowDetailsTemplate> </DataGrid> Now I'm not sure if I need to use a Triggers or Behaviors to accomplish this? Thanks for everyones help! FYI I'm using Silverlight 4.0 with Prism.
