• Why does xdebug crash apache on every XAMPP install I've tried?

  - by Ian Cook

  I've installed the Windows XAMPP package on three separate computers, 2 running Windows Vista 32 bit ( 1 Ultimate / 1 Home Premium ) and 1 running Windows Vista 64 Home Premium. After enabling xdebug in php.ini and restarting apache, viewing the default XAMPP localhost index causes apache to crash in the same way every time, reporting 'php_xdebug.dll' as the Fault Module Name. Here's the full report from the Windows Crash Reporter thing: Problem signature: Problem Event Name: APPCRASH Application Name: apache.exe Application Version: 2.2.9.0 Application Timestamp: 4853f994 Fault Module Name: php_xdebug.dll Fault Module Version: 2.0.3.0 Fault Module Timestamp: 47fcd9b9 Exception Code: c0000005 Exception Offset: 00008493 OS Version: 6.0.6001.2.1.0.768.3 Locale ID: 1033 Additional Information 1: a34a Additional Information 2: c9c5f4fd744690d388ab9d5b3eb051a7 Additional Information 3: cb2e Additional Information 4: 650bb5690556a17e911375b94d3e16f0 I've tried Googling this issue but haven't found any resolution, only reports of similar errors. EDIT: I enabled the extension line for php_xdebug.dll and that seems to have stopped the crashing so far.

• Zipping Rx IObservable with infinite number set

  - by Toni Kielo

  I have a IObservable [named rows in the sample below] from Reactive extensions framework and I want to add index numbers to each object it observes. I've tried to implement this using Zip function: rows.Zip(Enumerable.Range(1, int.MaxValue), (row, index) => new { Row = row, Index = index }) .Subscribe(a => ProcessRow(a.Row, a.Index), () => Completed()); .. but unfortunately this throws ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: disposables Am I understanding the Zip function wrong or is there a problem with my code? The Range part of the code doesn't seem to be the problem and the IObservable isn't yet receiving any events.

• Informix & .NET

  - by Giuliano

  I'm connecting to Informix 6.5 using the IBM OLE DB Driver. Some clarification: Informix Dynamic Server Workgroup Edition. Please note that there are many versions of IDS/WE - it helps to be precise about which version you have. It might be something like 10.00.TC1; the version number could be as old as 7.xx.TCx, or as new as 11.50.TCx. If your server is not on Windows but on Unix - or is on 64-bit Windows - the letter 'T' would change to 'U' (32-bit Unix) or 'F' (64-bit - Unix or Windows), or even 'H' (a particular HP-UX configuration). When I try to create a dataset using the VS DataSet wizard, after clicking on test connection it tells me 'Base Table not found'? The OLEDB driver is the official one provided by IBM. The problem with the 'Table not found' dialog is that Visual Studio doesn't tell me the table name but only the error! Has anyone else had this problem?

• How to set up an insert to a grails created file with next sequence number?

  - by Jack BeNimble

  I'm using a JMS queue to read from and insert data into a postgres table created by grails. The problem is obtaining the next sequence value. I thought I had found the solution with the following statement (by putting "DEFAULT" where the ID should go), but it's no longer working. I must have changed something, because I needed to recreate the table. What's the best way to get around this problem? ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (DEFAULT, 0, ?)"); UPDATE: In response to the suggested solution, I did the following: Added this to the the domain: class XmlTest { String xmlText static constraints = { id generator:'sequence', params:[name:'xmltest_sequence'] } } And changed the insert statement to the following: ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (nextval('xmltest_sequence'), 0, ?)"); However, when I run the statement, I get the following error: [java] 1 org.postgresql.util.PSQLException: ERROR: relation "xmltest_sequence" does not exist Any thoughts?

• Translate google co-ordinates to the pixels on picture.

  - by kalininew

  I have a city "map" (for example - Moscow). She in accuracy repeats the contours the given city in google maps (that is it is copied from google maps and it is a little processed, but the sense remained the same). Also I have object co-ordinates in a city (in co-ordinates of google). Problem: how to translate google co-ordinates to the co-ordinates of my picture (that is in pixels on OX and OY on a picture). That is I receive google-co-ordinates and it is necessary for me to draw this point on my picture. I know that on small scales (for example on city scales) it to make simply enough (it is necessary to learn what google-co-ordinates has one of picture corners, then to learn "price" of one pixel in google-co-ordinates on a picture on axes OX and OY separately). But on the big scales (country scale) "price" of one pixel will be not a constant, and will vary strongly enough and the method described above cannot be applied. How to solve a problem on country scales?

• Tomcat gzip while chunked issue

  - by hoodoos

  I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Content-Encoding: gzip Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recieved, but then after ungzipping I see that response is partial. I never seen such behavior with gzip turned off in request headers. So my question is: is it common tomcat issue? maybe one of it's mod which is doing compression? Or maybe it maybe some kind of proxy issue? I can't tell about versions of tomcat or what gzip mod they use, but feel free to ask, i'll try ask my service provider. Thanks.

• maths in Javascript.

  - by Jared

  Can someone please help me out with a javascript/jquery solution for this arithmetic problem... I need to subtract one number from the other. The problem is that the numbers have dollar signs (because its money). So it seems that jquery is treating them as strings instead of numbers. I have created two variables - toalAssets and totalLiabilites. I would like to subtract the latter from the former and place the result into another variable called netWorth Perhaps i need to use 'parseFloat'? But I'm not sure how - his is all a little over my head!

• Java,Tomcat,Sessions - JSessionId disappears

  - by Bob

  Hi, I'm having a problem with java sessions. I'm developing a simple web app, where I have to use sessions and session attributes. Everything is fine until I close my browser. When I close my browser the JSessionId disappears. Here's my code: request.getSession().setMaxInactiveInterval(30*60); //it's 30 minutes request.getSession().setAttribute("someinteger", 10); It works great, but when I shut down the browser, and reopen it I can't find the jsessionId (before I closed the browser I could find it in the 'localhost' section). The strange thing is I can still find the "someinteger" cookie. What is the problem? What am I doing wrong? I'm using this, too: link text, and it shows that JSESSIONID cookie expires : "SESSION", and "someinteger" expires in 30 minutes Thanks in advance.

• making apache and django add a trailing slash

  - by user302099

  Hello. My /train directory is aliased to a script in httpd.conf by: WSGIScriptAlias /train /some-path/../django.wsgi And it works well, except for one problem. If a user goes to /train (with no trailing slash) it will not redirect him to /train/, but will just give him the right page. This is a problem because this way the relative links on this page lead to the wrong place when no trailing slash was used to access it. How can this be worked out? Thanks.

• WinForms Form won't close on pressing X or Close() in C#

  - by MadBoy

  I'm having a bit weird problem with WinForm which seems to refuse to close for some weird reason. I've got very simple gui which sometimes doesn't react for me pressing X or when i use events on buttons it even reaches Close() and does nothing.. private void buttonZapisz_Click(object sender, EventArgs e) { string plik = textBoxDokumentDoZaladowania.Text; if (File.Exists(plik)) { string extension = Path.GetExtension(plik); string nazwaPliku = Path.GetFileName(plik); SqlMethods.databaseFilePut(plik, comboBoxTypDokumentu.Text, textBoxKomentarz.Text, sKlienciID, sPortfelID, extension, nazwaPliku); Close(); } } There are no events assigned to FormClosed or FormClosing. So how can I find out what's wrong. Sometimes X will work after the GUI is loaded but after i press Button to save some stuff to database it reaches Close() in that button event and it still is visible and does nothing. Can't use X, nor ALT+F4. I can go around GUI and choose other values for ComboBox without problem. I call GUI like this: private void contextMenuDokumentyDodaj_Click(object sender, EventArgs e) { var lv = (ListView) contextMenuDokumenty.SourceControl; string varPortfelID = Locale.ustalDaneListViewKolumny(listViewNumeryUmow, 0); string varKlienciID = Locale.ustalDaneListViewKolumny(listViewKlienci, 0); if (lv == listViewDokumentyPerKlient) { if (varKlienciID != "") { var dokumenty = new DocumentsGui(varKlienciID); dokumenty.Show(); dokumenty.FormClosed += varDocumentsGuiKlienci_FormClosed; } } else if (lv == listViewDokumentyPerPortfel) { if (varPortfelID != "" && varKlienciID != "") { var dokumenty = new DocumentsGui(varKlienciID, varPortfelID); dokumenty.Show(); dokumenty.FormClosed += varDocumentsGuiPortfele_FormClosed; } } } While I can't close GUI i can work on the main gui without problem too. I can open up same GUI and after opening new GUI i can quickly close it. GUI is very simple with few ComboBoxes,TextBoxes and one EditButton from Devexpress. Edit: varDocumentsGuiPortfele_FormClosed code allows me to refresh GUI (reload ListView's depending on where the user is on now). private void varDocumentsGuiPortfele_FormClosed(object sender, FormClosedEventArgs e) { TabControl varTabControl = tabControlKlientPortfele; if (varTabControl.TabPages.IndexOf(tabPageDokumentyPerKlient) == varTabControl.SelectedIndex) { loadTabControlKlientPortfeleBezZmianyUmowy(); } }

• Objective-C : Trouble with file download

  - by Holli

  I ran in a bit of trouble downloading files with Objective-C. I use the download decideDestinationWithSuggestedFilename from Apples documentation page. http://developer.apple.com/mac/library/documentation/cocoa/conceptual/URLLoadingSystem/Tasks/UsingNSURLDownload.html As long as I want to download just one file it works fine but I want to download an array for files one by one. The problem starts with the second file. Right now my code will trigger the next download itself from the downloadDidFinish Method. Then I will get an unrecognized selector sent to instance error. For me it looks like the NSURLDownload that just finished the download is still in use somehow. Release is called but the must be a problem. If I just put an NSBeep in the downloadDidFinished Method and trigger the next file download manually it works fine. Looks like I have to wait a while till I can start the next download. I know this question is a bit vague but maybe someone got an idea.

• Using mergedModelFromBundles: and versioning (CoreData)

  - by charlax

  Hi everybody, I'm trying to use the migration feature in CoreData. I've followed the Apple Documentation. I have a problem in the following method: /** Returns the managed object model for the application. If the model doesn't already exist, it is created by merging all of the models found in the application bundle. */ - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel != nil) { return managedObjectModel; } /* * NSInvalidArgumentException', reason: '*** -[NSCFArray insertObject:atIndex:]: attempt to insert nil' * 2010-02-17 16:27:15.338 Patrimoine[3037:207] */ managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain]; return managedObjectModel; } It appears that there is the same problem on http://iphonedevelopment.blogspot.com/2009/09/core-data-migration-problems.html Yet I did choose the method Apple suggests, by using the menu option "Add Model Version". Do you have any idea?

• Why is my app running

  - by John Smith

  I have compiled my iPhone app with setting (Device, Release). I install it on the test machine and it runs with no problem. Here's the problem. The app is linked to a C++ library. The compilation on the simulator has no errors. However the device compilation produces 568 errors, mostly about different visibilities w.r.t AppDelegate.o. They all look like: QL::Error::~Error()has different visibility (default) in /QL/build/Release-iphoneos/libQLLibrary.a(abcd.o) and (hidden) in /Programming/ObjC/Second/build/Second.build/Release-iphoneos/FG.build/Objects-normal/armv6/AppDelegate.o Why is this, and how can I stop the errors anyway?

• zsh: command not found: ls

  - by ABach

  I'm having a rather strange problem with zsh. When I start up my shell, everything - functions, environment vars, aliases, etc. - all work fine. I've created the following function and sourced it in zsh: clean() { for i in /tmp/* do echo $i done } Running clean in the terminal works as expected, in that it prints out all the files in /tmp/. Afterward, however, trying any command - for example, ls - produces this: zsh: command not found: ls I have several other functions that work just fine, which leads me to believe that somehow, that loop is causing the problem. At any rate, this is very frustrating and I would sincerely appreciate the community's eyes. Thanks!

• Doing 64 bit manipulation using 32 bit data in Fixed point arithmetic using C.

  - by Viks

  Hi, I am stuck with a problem. I am working on a hardware which only does support 32 bit operations. sizeof(int64_t) is 4. Sizeof(int) is 4. and I am porting an application which assumes size of int64_t to be 8 bytes. The problem is it has this macro BIG_MULL(a,b) ( (int64_t)(a) * (int64_t)(b) 23) The result is always a 32 bit integer but since my system doesn't support 64 bit operation, it always return me the LSB of the operation, rounding of all the results making my system crash. Can someone help me out? Regards, Vikas Gupta

• How to recover gracefully from a C# udp socket exception

  - by Gearoid Murphy

  Context: I'm porting a linux perl app to C#, the server listens on a udp port and maintains multiple concurrent dialogs with remote clients via a single udp socket. During testing, I send out high volumes of packets to the udp server, randomly restarting the clients to observe the server registering the new connections. The problem is this: when I kill a udp client, there may still be data on the server destined for that client. When the server tries to send this data, it gets an icmp "no service available" message back and consequently an exception occurs on the socket. I cannot reuse this socket, when I try to associate a C# async handler with the socket, it complains about the exception, so I have to close and reopen the udp socket on the server port. Is this the only way around this problem?, surely there's some way of "fixing" the udp socket, as technically, UDP sockets shouldn't be aware of the status of a remote socket? Any help or pointers would be much appreciated. Thanks.
