  • cfml error with application.cfc page

    - by tibin mathew
    Hi, I have some problem with my cfml website. I have used the below code in application.cfc file to connect with the dsn. But when ever i put this in my server, i'm getting error. i cant browse even a single test.cfm page. Is there any mistake in that code , any syntax error or something like that, will it be some problem with the dsn <cfset this.name = "0307de6.netsolhost.com"> <cfset this.sessionmanagement = true> <cfset this.loginstorage="session"> <cfset this.sessiontimeout = CreateTimeSpan(0,0,30,0)> <cfset this.applicationtimeout = CreateTimeSpan(2,0,0,0)> <cffunction name="onApplicationStart"> <cfscript> application.DSN = "hirerodsn"; application.dbUserName = "myusr"; application.dbPassword = "myd69!"; </cfscript> </cffunction> <cffunction name="onRequestStart"> <cfscript> request.DSN = "hirerodsn"; request.dbUserName = "myusr"; request.dbPassword = "myd69!"; </cfscript> </cffunction> please anyone help me

  • Sorting an array of Doubles with NaN in it

    - by Agent Worm
    This is more of a 'Can you explain this' type of question than it is anything else. I came across a problem at work where we were using NaN values in a table, but when the table was sorted, it came out in a very strange, strange manner. I figured NaN was mucking up something so I wrote up a test application to see if this is true. This is what I did. static void Main(string[] args) { double[] someArray = { 4.0, 2.0, double.NaN, 1.0, 5.0, 3.0, double.NaN, 10.0, 9.0, 8.0 }; foreach (double db in someArray) { Console.WriteLine(db); } Array.Sort(someArray); Console.WriteLine("\n\n"); foreach (double db in someArray) { Console.WriteLine(db); } Console.ReadLine(); } Which gave the result: Before: 4,2,NaN,1,5,3,NaN,10,9,8 After: 1,4,NaN,2,3,5,8,9,10,NaN So yes, the NaN some how made the sorted array to be sorted in a strange way. To quote Fry; "Why is those things?"

  • Designer serialization persistence problem in .NET, Windows Forms

    - by Jules
    ETA: I have a similar, smaller, problem here which, I suspect, is related to this problem. I have a class which has a readonly property that holds a collection of components (* not quite, see below). At design time, it's possible to select from the components on the design surface to add to the collection. (Think imagelist, but instead of selecting one, you can select as many as you want.) As a test, I inherit from button and attach my class to it as a property. The persistence problem occurs when I add a component,to the collection, from the design surface after I have added my button to the form. The best way to demonstrate this is to show you the designer generated code: Private Sub InitializeComponent() Dim Provider1 As WindowsApplication1.Provider = New WindowsApplication1.Provider Me.MyComponent2 = New WindowsApplication1.MyComponent Me.MyComponent1 = New WindowsApplication1.MyComponent Me.MyButton1 = New WindowsApplication1.MyButton Me.MyComponent3 = New WindowsApplication1.MyComponent Me.SuspendLayout() ' 'MyButton1 ' Me.MyButton1.ProviderCollection.Add(Me.MyButton1.InternalProvider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent1.Provider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent2.Provider) Me.MyButton1.ProviderCollection.Add(Provider1) //Wrong should be Me.MyComponent3.Provider ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub Friend WithEvents MyComponent1 As WindowsApplication1.MyComponent Friend WithEvents MyComponent2 As WindowsApplication1.MyComponent Friend WithEvents MyButton1 As WindowsApplication1.MyButton Friend WithEvents MyComponent3 As WindowsApplication1.MyComponent End Class As you can see from the code, the collection is not actually a collection of the components, but a collection of a property, 'Provider', from the components. It looks like the problem is occurring because MyComponent3 is created after MyButton. However, in my opinion, this should not make any difference - by the time the serializer comes to add the provider property of MyComponent3, it's already created. Note: You may wonder, why I'm not using AddRange to persist the collection. The reason for this is that if I do, the behaviour changes and none of the items will persist correctly. The designer will create local fields - like Provider1 - for each item in the collection. However if I add another collection to the class which holds the actual MyComponents and persist this, then, somehow, the AddRange method persists correctly in ProviderCollection! There seems to be some kind of quantum double slit experiment going down in code dom. How can I solve this problem?

  • Endless problems with a very simple python subprocess.Popen task

    - by Thomas
    I'd like python to send around a half-million integers in the range 0-255 each to an executable written in C++. This executable will then respond with a few thousand integers. Each on one line. This seems like it should be very simple to do with subprocess but i've had endless troubles. Right now im testing with code: // main() u32 num; std::cin >> num; u8* data = new u8[num]; for (u32 i = 0; i < num; ++i) std::cin >> data[i]; // test output / spit it back out for (u32 i = 0; i < num; ++i) std::cout << data[i] << std::endl; return 0; Building an array of strings ("data"), each like "255\n", in python and then using: output = proc.communicate("".join(data))[0] ...doesn't work (says stdin is closed, maybe too much at one time). Neither has using proc.stdin and proc.stdout worked. This should be so very simple, but I'm getting constant exceptions, and/or no output data returned to me. My Popen is currently: proc = Popen('aux/test_cpp_program', stdin=PIPE, stdout=PIPE, bufsize=1) Advise me before I pull my hair out. ;)

  • EJB3Unit testing no-tx-datasource

    - by justastefan
    Hello, I am doing tests on an ejb3-project using ejb3unit http://ejb3unit.sourceforge.net/Session-Bean.html for testing. All my Services long for @PersistenceContext (UnitName=bla). I set up the ejb3unit.properties like this: ejb3unit_jndi.1.isSessionBean=true ejb3unit_jndi.1.jndiName=ejb/MyServiceBean ejb3unit_jndi.1.className=com.company.project.MyServiceBean everything works with the in-memory-database. So now i want additionally test another servicebean with @PersistenceContext (UnitName=noTxDatasource) that goes for a defined in my datasources.xml: <datasources> <local-tx-datasource> ... </local-tx-datasource> <no-tx-datasource> <jndi-name>noTxDatasource</jndi-name> <connection-url>...</connection-url> <driver-class>oracle.jdbc.OracleDriver</driver-class> <user-name>bla</user-name> <password>bla</password> </no-tx-datasource> </datasources> How do I tell ejb3unit to make this work: Object object = InitialContext.doLookup("java:/noTxDatasource"); if (object instanceof DataSource) { return ((DataSource) object).getConnection(); } else { return null; } Currently it fails saying: javax.NamingException: Cannot find the name (noTxDataSource) in the JNDI tree Current bindings: (ejb/MyServiceBean=com.company.project.MyServiceBean) How can I add this no-tx-datasource to the jndi bindings?

  • MissingMethodException thrown when calling new form in Compact Framework

    - by Boerema
    I'm updating an old mobile device application for better flexibility. I had basically added the ability to configure the address of our SQL server in the case that we want to use our test server as opposed to our production server. I don't think this is causing the problem, but I wanted to state it. I also upgraded the project from a VS 2000 project to a VS 2005 project. The issue I am having is that when I try to run the program in the VS emulator for Pocket PC, I get an error. It occurs after our "main menu" form loads and the user selects the next form to load. The form is initialized without issue, but when we try to run the .ShowDialog() method, it throws a System.MissingMethodException. I don't have a lot of experience with the Compact Framework and really have no idea where to start looking for problems. I stepped the debugger through the entire initializing process for the new form and it ran without issue. But, again, when we come to the ShowDialog call, it throws the error. Any ideas in where to start looking or known issues would be greatly appreciated.

  • regular expression to remove original message from reply mail using in java ?

    - by ravi ravi
    In my forum, users can reply through email. I am handling mails from their reply. When they are replying the original message getting appended. I want to get only the reply message not the original message. I have to write regular expression for gmail & hotmail. I written regex for gmail as follows : \n.wrote:(?s).--End of Post-- It is removing the original message except date. I want to remove the date also. before removing the original message : " hi 33 On Tue, May 11, 2010 at 4:18 PM, Mmmmm, Rrrrr wrote: The following update has been posted to this discussion: test as user 222 [$MESSAGE_SIGNATURE_HEADER$] --End of Post-- " When I use the above regex it is filtering as follows : " hi 33 On Tue, May 11, 2010 at 4:18 PM, Mmmmm, Rrrrr " Here i want only the actual message 'hi 33' not that date. How can I filter the date using above regex? Also I need regex for Hotmail also. I appreciate for any reply. Thanks in advance.

  • Does "for" in .Net Framework 4.0 execute loops in parallel? Or why is the total not the sum of the p

    - by Shiraz Bhaiji
    I am writing code to performance test a web site. I have the following code: string url = "http://xxxxxx"; System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch(); System.Diagnostics.Stopwatch totalTime = new System.Diagnostics.Stopwatch(); totalTime.Start(); for (int i = 0; i < 10; i++) { stopwatch.Start(); WebRequest request = HttpWebRequest.Create(url); WebResponse webResponse = request.GetResponse(); webResponse.Close(); stopwatch.Stop(); textBox1.Text += "Time Taken " + i.ToString() + " = " + stopwatch.Elapsed.Milliseconds.ToString() + Environment.NewLine; stopwatch.Reset(); } totalTime.Stop(); textBox1.Text += "Total Time Taken = " + totalTime.Elapsed.Milliseconds.ToString() + Environment.NewLine; Which is giving the following result: Time Taken 0 = 88 Time Taken 1 = 161 Time Taken 2 = 218 Time Taken 3 = 417 Time Taken 4 = 236 Time Taken 5 = 217 Time Taken 6 = 217 Time Taken 7 = 218 Time Taken 8 = 409 Time Taken 9 = 48 Total Time Taken = 257 I had expected the total time to be the sum of the individual times. Can anybody see why it is not?

  • Django tests failing on invalid keyword argument

  • App session cookie not being created in Rails, sporadically

    - by James
    Hi everyone, This is an issue sporadically for very few users, however we haven't been able to replicate it. However I have now got a Chrome instance (Mac) which is reproducing the error (for some unknown reason), and I hope to not restart it until I have this nailed! Rails application, using memcached for session store. While the bug manifests in the _app_session_id cookie not being created, our javascript-generated cookie test and app-generated language cookies are being created successfully. This means that InvalidAuthenticityToken errors are thrown for every form that is submitted by those afflicted - people can't log into the app. The error occurs across all browsers - had reports for IE7 and Firefox (which most users use). Switching to another browser often fixes the issue (though not always), and standard cache-cookie-clear tactics do not. So now that I have got Chrome open which is having the same issue - in development, staging and live environments (meaning http and https). All other browsers are fine. I've restarted the servers and restarted memcached. I don't really want to restart Chrome - in the risk that the issue does go away with that (having said that, it hasn't worked for users). I've been tcpdumping the requests - and although I'll keep digging, I'd love it if anyone had any suggestions, places to start looking, anything. This is really painful ;) Thanks!

  • Using Regex Replace when looking for un-escaped characters

    - by Daniel Hollinrake
    I've got a requirement that is basically this. If I have a string of text such as "There once was an 'ugly' duckling but it could never have been \'Scarlett\' Johansen" then I'd like to match the quotes that haven't already been escaped. These would be the ones around 'ugly' not the ones around 'Scarlett'. I've spent quite a while on this using a little C# console app to test things and have come up with the following solution. private static void RegexFunAndGames() { string result; string sampleText = @"Mr. Grant and Ms. Kelly starred in the film \'To Catch A Thief' but not in 'Stardust' because they'd stopped acting by then"; string rePattern = @"\\'"; string replaceWith = "'"; Console.WriteLine(sampleText); Regex regEx = new Regex(rePattern); result = regEx.Replace(sampleText, replaceWith); result = result.Replace("'", @"\'"); Console.WriteLine(result); } Basically what I've done is a two step process find those characters that have already been escaped, undo that then do everything again. It sounds a bit clumsy and I feel that there could be a better way.

  • IIS6 configuration for WCF/Silverlight

    - by Grayson Mitchell
    I am trying the simple senario of running a WCF service to return Active directory information on a user. (http://rouslan.com/2009/03/20-steps-to-get-together-windows-authentication-silverlight-and-wcf-service/) using Silverlight 4 & .net 4 However, I am being driven insane by trying to set this up in IIS. Currently I have my solution working in VS, but when I try to run the service in ISS a debug window tries to open... (and I can't get rid of it, is is complaining about the WCF call). <basicHttpBinding> <binding name="winAuthBasicHttpBinding"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm"/> </security> </binding> </basicHttpBinding> The Insanity: I have got the IIS to successfully call a WCF service (but can't reproduce), I have created 5 projects to try and get this working, but in my 5th I can't even browse the site (says it can't download silverlight application, but mime type are setup). My next step is to install Server2008 on a test machine and try IIS7... as all the various walkthrough's I have found just dont seem to work in IIS6.

  • RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

    - by Ed
    I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

  • MSMQ on Win2008 R2 won’t receive messages from older clients

    - by Graffen
    Hi all I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

  • Generate exe in .Net

    - by rwallace
    In .Net, you can generate byte code in memory, and presumably save the resulting program to a .exe file. To do the first step, I have the following test code adapted from http://www.code-magazine.com/Article.aspx?quickid=0301051 var name = new AssemblyName(); name.Name = "MyAssembly"; var ad = Thread.GetDomain(); var ab = ad.DefineDynamicAssembly(name, AssemblyBuilderAccess.Run); var mb = ab.DefineDynamicModule("MyModule"); var theClass = mb.DefineType("MathOps", TypeAttributes.Public); var retType = typeof(System.Int32); var parms = new Type[2]; parms[0] = typeof(System.Int32); parms[1] = typeof(System.Int32); var meb = theClass.DefineMethod("ReturnSum", MethodAttributes.Public, retType, parms); var gen = meb.GetILGenerator(); gen.Emit(OpCodes.Ldarg_1); gen.Emit(OpCodes.Ldarg_2); gen.Emit(OpCodes.Add_Ovf); gen.Emit(OpCodes.Stloc_0); gen.Emit(OpCodes.Br_S); gen.Emit(OpCodes.Ldloc_0); gen.Emit(OpCodes.Ret); theClass.CreateType(); How do you do the second step, and save the result to a .exe?

  • error handler isn't called when file is uploaded via ajax using jQuery form plugin

    - by scompt.com
    Here's my test case. If the form is posted, a 500 error response is sent. If not, the form is sent. If the file input tag is commented out, the error handler is called. If the file input tag is present, the error handler isn't called. I think this might have something to do with the fact that jQuery needs to use an iframe to handle the upload and iframes don't seem to respond to the error handler. Edit: If I add iframe: true to the options passed to ajaxSubmit to force the use of an iframe, the non-file-upload case stops working also, so it definitely has to do with the iframe. Edit2: I'm using the jQuery Form Plugin. <?php if($_SERVER['REQUEST_METHOD'] == 'POST') { header('HTTP/1.1 500 Internal Server Error'); die; } else {?> <html><head> <script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js?ver=2.9.2'></script> <script type='text/javascript' src='http://github.com/malsup/form/raw/master/jquery.form.js?v2.43'></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery('a').click(function() {jQuery('form').ajaxSubmit({error: function(){alert('error handler called');}})}); }); </script> </head><body> <form method="POST"> <input type="text" name="mytext" /> <input type="file" name="myfile" /><!-- comment this element out --> <input type="hidden" name="blah" value="blah" /> <a>submit</a> </form> </body></html> <?php } Is there any way to get the error handler to be called in both situations?

  • Small-o(n^2) implementation of Polynomial Multiplication

    - by AlanTuring
    I'm having a little trouble with this problem that is listed at the back of my book, i'm currently in the middle of test prep but i can't seem to locate anything regarding this in the book. Anyone got an idea? A real polynomial of degree n is a function of the form f(x)=a(n)x^n+?+a1x+a0, where an,…,a1,a0 are real numbers. In computational situations, such a polynomial is represented by a sequence of its coefficients (a0,a1,…,an). Assuming that any two real numbers can be added/multiplied in O(1) time, design an o(n^2)-time algorithm to compute, given two real polynomials f(x) and g(x) both of degree n, the product h(x)=f(x)g(x). Your algorithm should **not** be based on the Fast Fourier Transform (FFT) technique. Please note it needs to be small-o(n^2), which means it complexity must be sub-quadratic. The obvious solution that i have been finding is indeed the FFT, but of course i can't use that. There is another method that i have found called convolution, where if you take polynomial A to be a signal and polynomial B to be a filter. A passed through B yields a shifted signal that has been "smoothed" by A and the resultant is A*B. This is supposed to work in O(n log n) time. Of course i am completely unsure of implementation. If anyone has any ideas of how to achieve a small-o(n^2) implementation please do share, thanks.

  • java recursion on array

    - by user69514
    I have to create a program that finds all the possible ways of filling a board of size 3xN You place a domino which takes up 2 spaces to completely fill the board. So far, this is my thought process on how it should be done based on what the teacher has said as well as my own thoughts. Get input and check if its even or odd If it's odd, the board can't be filled all the way and the program ends If it's even, place a domino horizontally in the top right corner of the board Test if you can place a domino vertically in that spot. Repeat those two steps as many times as possible. The problem is I don't know how to code it to the point where you can remember the placements of each domino. I can get it to where it fills the board completely once and maybe twice, but nothing past that. I also know that I'm supposed to use recursion to figure this out fwiw. Here is the code I started on so far. There is also a main method and I have the initial even/odd check working fine. This is the part I have no idea on. public void recurDomino(int row, int column) { if (Board[2][x - 1] != false) { } else if(Board[1][x-1]!=false) { } else { for (int n=0; n < x - 1; n++) { Board[row][column] = true; Board[row][column+1] = true; column++; counter++; } recurDomino(1, 0); recurDomino(2, 0); } } Thank you for any help you guys can give me.

    We have a WinForms desktop application, which is heavily multithreaded. 3 threads run with Application.Run and a bunch of other background worker threads. Getting all the threads to shut down properly was kind of tricky, but I thought I finally got it right. But when we actually deployed the application, users started experiencing the application not exiting. There's a System.Threading.Mutex to prevent them from running the app multiple times, so they have to go into task manager and kill the old one before they can run it again. Every thread gets a Thread.Join before the main thread exits, and I added logging to each thread I spawn. According to the log, every single thread that starts also exits, and the main thread also exits. Even stranger, running SysInternals ProcessExplorer show all the threads disappear when the application exits. As in, there are 0 threads (managed or unmanaged), but the process is still running. I can't reproduce this on any developers computers or our test environment, and so far I've only seen it happen on Windows XP (not Vista or Windows 7 or any Windows Server). How can a process keep running with 0 threads?

  • fsockopen soap request

    - by gosom
    I am trying to send a SOAP message to a service using php. I want to do it with fsockopen, here's is the code : <?php $fp = @fsockopen("ssl://xmlpropp.worldspan.com", 443, $errno, $errstr); if (!is_resource($fp)) { die('fsockopen call failed with error number ' . $errno . '.' . $errstr); } $soap_out = "POST /xmlts HTTP/1.1\r\n"; $soap_out .= "Host: 212.127.18.11:8800\r\n"; //$soap_out .= "User-Agent: MySOAPisOKGuys \r\n"; $soap_out .= "Content-Type: text/xml; charset='utf-8'\r\n"; $soap_out .= "Content-Length: 999\r\n\r\n"; $soap_put .= "Connection: close\r\n"; $soap_out .= "SOAPAction:\r\n"; $soap_out .= ' Worldspan This is a test '; if(!fputs($fp, $soap_out, strlen($soap_out))) echo "could not write"; echo "<xmp>".$soap_out."</xmp>"; echo "--------------------<br>"; while (!feof($fp)) { $soap_in .= fgets($fp, 100); } echo "<xmp>$soap_in</xmp>"; fclose($fp); echo "ok"; the above code just hangs . if i remove the while it types ok, so i suppose the problem is at $soap_in .= fgets($fp, 100) Any ideas of what is happening

  • Can SOTI's MobiControl software interfere with an ASP.Net web service?

    - by MusiGenesis
    We have a set of WinMo (5.0) devices running a .NET CF application that talks to an ASP.Net web service running on a server. The devices connect to the network either via ActiveSync through a networked PC or directly to the network via an Ethernet dongle. In our development environment, the communication between devices and web service is 100% reliable. In our production environment, the communications are failing erratically and unpredictably. Sometimes calls to the web service (even to a simple test call that just returns a boolean) begin failing every time on a particular device, with the error message "Could not establish connection to network." This is usually fixed by flip-flopping the selected combo box values on the SETTINGS | NETWORKS screen. Sometimes calls on a particular device begin failing with a generic "WebException" message. The fix for this problem (so far) is either to reset the device (i.e. reinstall the OS) or else it just can't be fixed on some devices. To the best of our knowledge, everything about the DEV and PROD systems are the same (same server and device specs). The most obvious difference to us is that the PROD devices are all controlled by SOTI's MobiControl (which is server-side software that communicates with a SOTI client application installed on each device), whereas our DEV environment does not have SOTI installed anywhere (obviously we should have it there as well - long story). Does anybody have any experience with SOTI MobiControl and/or know of any documented problems where SOTI interferes with other communication mechanisms on a device?
