• Access control for cross site requests in Internet Explorer

  - by Aleksandar

  I am trying to make an AJAX call from several domains to a single one which will handle the request. Enabling Cross domain in Firefox and Chrome was easy by setting the header on the handling server: header("Access-Control-Allow-Origin: *"); But this doesn't help enabling it in Internet Explorer. When I try: httpreq.send(''); it stops with error Access denied. How can this be enabled in Internet Explorer?

• Searching for specific HTML string using Python

  - by Morpheous

  What modules would be the best to write a python program that searches through hundreds of html documents and deletes a certain string of html that is given. For instance, if I have an html doc that has <a href="test.html">Test</a> and I want to delete this out of every html page that has it. Any help is much appreciated, and I don't need someone to write the program for me, just a helpful point in the right direction.

• Windows forms application blocks after station lock

  - by Silviu

  We're having a serious issue at work. We've discovered that after the station where the client was running is locked/unlocked the client is blocked. No repaint. So the UI thread is blocked with something. Looking at the callstack of the UI thread (thread 0) using windbg we see that a UserPreferenceChanged event gets raised. It is marshalled through a WindowsFormsSynchronizationContext using it's controlToSend field to the UI. It gets blocked by a call to the marshalling control. The method called is MarshaledInvoke it builds a ThreadMethodEntry entry = new ThreadMethodEntry(caller, method, args, synchronous, executionContext); This entry is supposed to do the magic. The call is a synchronous call and because of that (still in the MarshaledInvoke of the Control class) the wait call is reached: if (!entry.IsCompleted) { this.WaitForWaitHandle(entry.AsyncWaitHandle); } The last thing that i can see on the stack is the WaitOne called on the previously mentioned AsyncWaitHandle. This is very annoying because having just the callstack of the runtime and not one of our methods being invoked we cannot really point to a bug in our code. I might be wrong, but I'm guessing that the marshaling control is not "marshaling" to the ui thread. But another one...i don't really know which one because the other threads are being used by us and are blocked...maybe this is the issue. But none of the other threads are running a message loop. This is very annoying. We had some issues in the past with marshaling controls to the right ui thread. That is because the first form that is constructed is a splash form. Which is not the main form. We used to use the main form to marshal call to the ui thread. But from time to time some calls would go to a non ui thread and some grids would broke with a big red X on them. I fixed this by creating a specific class: public class WindowsFormsSynchronizer { private static readonly WindowsFormsSynchronizationContext = new WindowsFormsSynchronizationContext(); //Methods are following that would build the same interface of the synchronization context. } This class gets build as one of the first objects in the first form being constructed. We've noticed some other strange thing. Looking at the heap there are 7 WindowsFormsSynchronizationContext objects. 6 of these have the same instance of controlToSend, and the other one has some different instance of controlToSend. This last one is the one that should marshal the calls to the UI. I don't have any other idea...maybe some of you guys had this same issue?

• Why isn't there a good scheme/lisp on llvm?

  - by anon

  There is Gambit scheme, MIT scheme, PLT scheme, chicken scheme, bigloo, larceny, ...; then there are all the lisps. Yet, there's not (to my knowledge) a single popular scheme/lisp on LLVM, even though LLVM provides lots of nice things like: easier to generate code than x85 easy to make C ffi calls ... So why is it that there isn't a good scheme/lisp on LLVM?

• best way to deal with python pdb flakiness re/stdout?

  - by YGA

  I love python and hate the pdb debugger. For instance, if I have a program where stdout is redirected, my pdb prompts all go to the redirection, because the library was written to write to stdout. Oftentimes this problem is subtle, causing me to think a program is hanging when it's really waiting for input. How do people work around this? (Unfortunately, using other debuggers like winpdb is not an option). Thanks, /YGA

• Multi-Page invoice printing on one page

  - by ryan

  I have an invoice that contains over 100 lines of product that I am trying to print. This single invoice should take over 3 pages, but when printed, the content flows off the footer and the next page is the following invoice. I am using divs instead of tables, and I can't understand why the long invoices will not print on multiple pages. Any ideas?

• Is there an implementation of Tom Kyte's STRAGG function supporting SQL Server?

  - by s_rajasekar

  STRAGG function implemention returns a result as a single column value. Implementation for Oracle seems pretty generic and can be consumed for different tables (and relationships). Could similar behavior be achieved for SQL Server. A search in the web, appears to return only hard coded implementations and not a generic one. Do we have any known solution for Sql server?

• What Character Encoding Is This?

  - by Canoehead

  I need to clean up some file containing French text. Problem is that the files erroneously contain multiple encodings within the same file. I think some sections are ISO8859-1 (Latin 1) but other parts have text encoded in single byte characters that look like 'extended' ASCII. In other words, it is UTF-7 encoding plus the following: 0x82 for é (e acute) 0x8a for è (e grave) 0x88 for ê (e circumflex) 0x85 for à (a grave) 0x87 for ç (c cedilla) What encoding is this?

So a select on this single field from to rows will output 3 lines for first row and 2 lines for second row: Row1 designationer nye kolonier mindre byer Row2 udsteder bopladser I would like to do a select that select all these lines as if they had been rows in the table like: SELECT do_the_split(field) FROM table so the result would be more like: Row1 designationer Row2 nye kolonier Row3 mindre byer Row4 udsteder Row5 bopladser is there any way to do this in MySQL?

• Detecting when an embedded Jetty server is fully initialized.

  - by Luke

  I have embedded Jetty in a java application and am calling the start() method on an instance of the Jetty server object (after setting a handler list which describes the location of the static and dynamic web content). Does the start() call block until initialization is complete? If not, how do I determine when the server is fully started and ready to receive requests?

• What happens when I subscribe to a message using NServiceBus?

  - by Ben Aston

  When I subscribe as the recipient of a certain type of message using NServiceBus Bus.Subscribe<MyMessage>() What am I actually doing? Am I specifying that a particular method on the recipient type will be invoked upon message receipt? If so, within what context does the method run - in a static context, or within the context of a new'd-up parent class instance (and if so, how does NServiceBus know what constructor to use)?

• Avaudioplayer problem regarding songs

  - by Arun Sharma

  I am using avaudioplayer for playing mp3 songs. The problem is in being able to catch the instance of the player to control it i.e. Stop it, Play it etc. The code by default creates multiple instances of the same player and overlaps the songs. I am being unable to reference the player specifically. Do you have an idea as to how we can do so? Thanks Arun Sharma

• Should Application_End fire on an automatic App Pool Recycle?

  - by Laramie

  I have read this, this, this and this plus a dozen other posts/blogs. I have an ASP.Net app in shared hosting that is frequently recycling. We use NLog and have the following code in global.asax void Application_Start(object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nAPPLICATION STARTING\r\n\r\n"); } protected void Application_OnEnd(Object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nAPPLICATION_OnEnd\r\n\r\n"); } void Application_End(object sender, EventArgs e) { HttpRuntime runtime = (HttpRuntime)typeof(System.Web.HttpRuntime).InvokeMember("_theRuntime", BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.GetField, null, null, null); if (runtime == null) return; string shutDownMessage = (string)runtime.GetType().InvokeMember("_shutDownMessage", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); string shutDownStack = (string)runtime.GetType().InvokeMember("_shutDownStack", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); ApplicationShutdownReason shutdownReason = System.Web.Hosting.HostingEnvironment.ShutdownReason; NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug(String.Format("\r\n\r\nAPPLICATION END\r\n\r\n_shutDownReason = {2}\r\n\r\n _shutDownMessage = {0}\r\n\r\n_shutDownStack = {1}\r\n\r\n", shutDownMessage, shutDownStack, shutdownReason)); } void Application_Error(object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nApplication_Error\r\n\r\n"); } Our log file is littered with "APPLICATION STARTING" entries, but neither Application_OnEnd, Application_End, nor Application_Error are ever fired during these spontaneous restarts. I know they are working because there are entries for touching the web.config or /bin files. We also ran a memory overload test and can trigger an OutOfMemoryException which is caught in Application_Error. We are trying to determine whether the virtual memory limit is causing the recycling. We have added GC.GetTotalMemory(false) throughout the code, but this is for all of .Net, not just our App´s pool, correct? We've also tried var oPerfCounter = new PerformanceCounter(); oPerfCounter.CategoryName = "Process"; oPerfCounter.CounterName = "Virtual Bytes"; oPerfCounter.InstanceName = "iisExpress"; logger.Debug("Virtual Bytes: " + oPerfCounter.RawValue + " bytes"); but don't have permission in shared hosting. I've monitored the app on a dev server with the same requests that caused the recycles in production with ANTS Memory Profiler attached and can't seem to find a culprit. We have also run it with a debugger attached in dev to check for uncaught exceptions in spawned threads that might cause the app to abort. My questions are these: How can I effectively monitor memory usage in shared hosting to tell how much my application is consuming prior to an application recycle? Why are the Application_[End/OnEnd/Error] handlers in global.asax not being called? How else can I determine what is causing these recycles? Thanks.
