  • jQuery/Ajax/javascript in FireFox Error when using $.post/$.get

    - by IsenGrim
    uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://localhost/scripts/jQuery.js :: anonymous :: line 808" data: no] Line 0 is the error i get when i bring up firebug. This only happens in firefox (and maybe other browsers) but the code works fine in IE8. I have codes like this in jquery: $("#Logout").live("click", function (e) { e.preventDefault(e); $.post("/logout.php", {}, function () { //--a bunch of animations--// window.location = "/login.php"; } }); I have no idea whats wrong as even the error message is not helpful at all.. inside logout.php: <?php session_start(); session_destroy(); ?> Also dont work if I used GET or inserted phantom data. Or is there a more elegant way to do this?

  • Multiplying matrices: error: expected primary-expression before 'struct'

    - by justin
    I am trying to write a program that is supposed to multiply matrices using threads. I am supposed to fill the matrices using random numbers in a thread. I am compiling in g++ and using PTHREADS. I have also created a struct to pass the data from my command line input to the thread so it can generate the matrix of random numbers. The sizes of the two matrices are also passed in the command line as well. I keep getting: main.cpp:7: error: expected primary-expression before 'struct' my code @ line 7 =: struct a{ int Arow; int Acol; int low; int high; }; My inpust are : Sizes of two matrices ( 4 arguments) high and low ranges in which o generate the random numbers between. Complete code: [headers] using namespace std; void *matrixACreate(struct *); void *status; int main(int argc, char * argv[]) { int Arow = atoi(argv[1]); // Matrix A int Acol = atoi(argv[2]); // WxX int Brow = atoi(argv[3]); // Matrix B int Bcol = atoi(argv[4]); // XxZ, int low = atoi(argv[5]); // Range low int high = atoi(argv[6]); struct a{ int Arow; // Matrix A int Acol; // WxX int low; // Range low int high; }; pthread_t matrixAthread; //pthread_t matrixBthread; pthread_t runner; int error, retValue; if (Acol != Brow) { cout << " This matrix cannot be multiplied.

  • Dynamically/recursively building hashes in Perl?

    - by Gaurav Dadhania
    I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, but all I could find were introductory articles about hashes. I would be grateful if you point me towards the right direction or suggest a nice article/tutorial. I'm trying to read from a file which has paths in the form of one/two/three four five/six/seven/eight and I want to build a hash like VAR = { one : { two : { three : "" } } four : "" five : { six : { seven : { eight : "" } } } } The script I'm using currently is : my $finalhash = {}; my @input = <>; sub constructHash { my ($hashrf, $line) = @_; @elements = split(/\//, $line); if(@elements > 1) { $hashrf->{shift @elements} = constructHash($hashrf->{$elements[0]}, @elements ); } else { $hashrf->{shift @elements} = ""; } return $hashrf; } foreach $lines (@input) { $finalhash = constructHash($finalhash, $lines); }

  • Force NCover 1.5.8 to use v4 framework like testdriven.net does?

    - by Sam Holder
    I want to run coverage from the command line, but can't seem to get NCover 1.5.8 to instrument the code. It must be possible as when I run coverage tests with TestDriven.net it works. the difference seems to be that TD.NET is able to get NCover to use framework 4.0 (you get this in the log when it runs : MESSAGE: v4.0.30319) but from the command line I can't make it (I get this in the log : MESSAGE: v2.0.50727) So how can I make NCover play nice with nunit from the commandline, like it does with TD.NET?

  • getting java.lang.OutOfMemoryError exception while running a Midlet (using netbeans)

    - by Jeeka
    I am writing a Midlet(using Netbeans) which reads a file containing exactly 2400 lines (each line being 32 characters long) and (extract a part of each line) puts them in an array. I am doing the same for 11 such files( all files have exactly 2400 lines).The Midlet runs fine for reading 6 files and putting them in 6 arrays. However, the Midlet stops while doing it for the 7th file throwing the following exception: TRACE: , startApp threw an Exception java.lang.OutOfMemoryError (stack trace incomplete) java.lang.OutOfMemoryError (stack trace incomplete) I have tried the modifying the netbeans.conf file to increase the heap memory ( as suggested by many forums and blogs) but nothing works for me. Here are the parameters that i had modified in the netbeans.conf file: -J-Xss2m -J-Xms1024m -J-Xmx1024m -J-XX:PermSize=1024m -J-XX:MaxPermSize=1536m -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled Can anyone please help me to get me out of this !

  • Bash or python for changing spacing in files

    - by Werner
    Hi, I have a set of 10000 files. In all of them, the second line, looks like: AAA 3.429 3.84 so there is just one space (requirement) between AAA and the two other columns. The rest of lines on each file are completely different and correspond to 10 columns of numbers. Randomly, in around 20% of the files, and due to some errors, one gets BBB 3.429 3.84 so now there are two spaces between the first and second column. This is a big error so I need to fix it, changing from 2 to 1 space in the files where the error takes place. The first approach I thought of was to write a bash script that for each file reads the 3 values of the second line and then prints them with just one space, doing it for all the files. I wonder what do oyu think about this approach and if you could suggest something better, bashm python or someother approach. Thanks

  • Gracefully avoiding NullPointerException in Java

    - by Yuval A
    Consider this line: if (object.getAttribute("someAttr").equals("true")) { // .... Obviously this line is a potential bug, the attribute might be null and we will get a NullPointerException. So we need to refactor it to one of two choices: First option: if ("true".equals(object.getAttribute("someAttr"))) { // .... Second option: String attr = object.getAttribute("someAttr"); if (attr != null) { if (attr.equals("true")) { // .... The first option is awkward to read but more concise, while the second one is clear in intent, but verbose. Which option do you prefer in terms of readability?

  • Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

    - by Pentium10
    I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

  • System.Diagnostics.Debugger.Debug() stopped working

    - by Andrew Miner
    I'm working on a program which uses the System.Diagnostics.Debugger.Break() method to allow the user to set a breakpoint from the command-line. This has worked fine for many weeks now. However, when I was working on fixing a unit test today, I tried to use the debug switch from the command-line, and it didn't work. Here's what I've tried: I've confirmed that the Debug() method is really being called (by putting a System.Console.WriteLine() after it) I've confirmed that the build is still in Debug I've done a clean build I've restarted Product Studio A quick Google search didn't reveal anything, and the API documentation for .Net doesn't mention anything about this function not performing correctly. So... any ideas?

  • "_FILE_AND_LINE_ is not defined in this scope" (compiling RakNet NAT examples in OS X)

    - by Michael F
    Hello! I'm working on a RakNet-based project (using 3.8 on OS X 10.6), and I'm trying to work through the various examples that demonstrate the parts of RakNet I want to use. For the "NatCompleteClient" example, I've imported the source into a command-line project in XCode, along with the UPNP dependency. At compile time I've had a few errors in the UPNP section, though, and I can't find any guidance on this. In UPNPPortForwarder.mm, there are 7 lines that use _FILE_AND_LINE_, and the compiler is not happy; for example on line 232: foundInterfaces.Deallocate(r1,_FILE_AND_LINE_); causes: UPNPPortForwarder.mm:232: error: '_FILE_AND_LINE_' was not declared in this scope Can anyone tell me what this is all about? That variable doesn't seem to get talked about very often... or Google doesn't like to find it.

  • ASP.Net Checkbox Doesn't Allow Setting Visible to True

    - by Shawn Steward
    I'm working on an old web application in Visual Studio .Net 2003 (yeeich) and I'm having an issue with a Checkbox that will not set the Visibility to True. It's declared as such: Protected WithEvents chkTraining As System.Web.UI.WebControls.CheckBox and <asp:CheckBox id="chkTraining" runat="server" Visible="False"></asp:CheckBox> When I am debugging through the line that has: chkTraining.Visible = True it goes past it fine, but as I check this value on the very next line, chkTraining.Visible = False. What could possibly be going on here? There's no events firing off or anything else going on... this really is throwing me for a loop. Thanks for your help.

  • Python: User-Defined Exception That Proves The Rule

    - by bandana
    Python documentations states: Exceptions should typically be derived from the Exception class, either directly or indirectly. the word 'typically' leaves me in an ambiguous state. consider the code: class good(Exception): pass class bad(object): pass Heaven = good() Hell = bad() >>> raise Heaven Traceback (most recent call last): File "<pyshell#163>", line 1, in <module> raise Heaven good >>> raise Hell Traceback (most recent call last): File "<pyshell#171>", line 1, in <module> raise Hell TypeError: exceptions must be classes or instances, not bad so when reading the python docs, should i change 'typically' with ''? what if i have a class hierarchy that has nothing to do with the Exception class, and i want to 'raise' objects belonging to the hierarchy? i can always raise an exception with an argument: raise Exception, Hell This seems slightly awkward to me What's so special about the Exception class, that only its family members can be raised?

  • Linux issues on setting a timer function

    - by laura
    I am creating a process with 2 children, 1 of the children is responsible to read questions (line by line from a file), output every question and reading the answer, and the other one is responsable to measure the time elapsed and notify the user at each past 1 minute about the remaining time. My problem is that i couldn't find any useful example of how i can make this set time function to work. Here is what i have tried so far. The problem is that it outputs the same elapsed time every time and never gets out from the loop. #include<time.h> #define T 600000 int main(){ clock_t start, end; double elapsed; start = clock(); end = start + T; while(clock() < end){ elapsed = (double) (end - clock()) / CLOCKS_PER_SEC; printf("you have %f seconds left\n", elapsed); sleep(60); } return 0; }

  • SVN Merge returns nothing...

    - by Mike
    Here is the scenario: Windows Vista environment. SVN version 1.6.11. I'm on my branch directory. I want to update my branch with a particular change from my trunk. Using command line (using SlikSVN) I enter the following and it returns nothing (returns a blank line and no merge occurs): svn merge -r 11846:11891 http://trunk//AppConstants.java When I do the equivalent using Tortoise SVN, it says "Completed" but nothing gets merged either. When I do a svn diff I clearly see the differences I want to merge in from the trunk to my branch. The diff command I am using is svn diff -r 11846:11891 http://trunk//AppConstants.java. Can anyone figure why no merge occurs? Thanks!!!

  • Which network protocol to use for lightweight notification of remote apps?

    - by Chris Thornton
    I have this situation.... Client-initiated SOAP 1.1 communication between one server and let's say, tens of thousands of clients. Clients are external, coming in through our firewall, authenticated by certificate, https, etc.. They can be anywhere, and usually have their own firewalls, NAT routers, etc... They're truely external, not just remote corporate offices. They could be in a corporate/campus network, DSL/Cable, even Dialup. Client uses Delphi (2005 + SOAP fixes from 2007), and the server is C#, but from an architecture/design standpoint, that shouldn't matter. Currently, clients push new data to the server and pull new data from the server on 15-minute polling loop. The server currently does not push data - the client hits the "messagecount" method, to see if there is new data to pull. If 0, it sleeps for another 15 min and checks again. We're trying to get that down to 7 seconds. If this were an internal app, with one or just a few dozen clients, we'd write a cilent "listener" soap service, and would push data to it. But since they're external, sit behind their own firewalls, and sometimes private networks behind NAT routers, this is not practical. So we're left with polling on a much quicker loop. 10K clients, each checking their messagecount every 10 seconds, is going to be 1000/sec messages that will mostly just waste bandwidth, server, firewall, and authenticator resources. So I'm trying to design something better than what would amount to a self-inflicted DoS attack. I don't think it's practical to have the server send soap messages to the client (push) as this would require too much configuration at the client end. But I think there are alternatives that I don't know about. Such as: 1) Is there a way for the client to make a request for GetMessageCount() via Soap 1.1, and get the response, and then perhaps, "stay on the line" for perhaps 5-10 minutes to get additional responses in case new data arrives? i.e the server says "0", then a minute later in response to some SQL trigger (the server is C# on Sql Server, btw), knows that this client is still "on the line" and sends the updated message count of "5"? 2) Is there some other protocol that we could use to "ping" the client, using information gathered from their last GetMessageCount() request? 3) I don't even know. I guess I'm looking for some magic protocol where the client can send a GetMessageCount() request, which would include info for "oh by the way, in case the answer changes in the next hour, ping me at this address...". Also, I'm assuming that any of these "keep the line open" schemes would seriously impact the server sizing, as it would need to keep many thousands of connections open, simultaneously. That would likely impact the firewalls too, I think. Is there anything out there like that? Or am I pretty much stuck with polling? TIA, Chris

  • Where/When does C# and the .NET Framework fail to be the right tool?

    - by Nate Bross
    In my non-programming life, I always attempt to use the approprite tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, powershell, batch files, and Java, as well as being versed in the web technologes (javascript, html/css). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. The bottom line here, is that I feel that I'm choosing C# and .NET simply because I am very comfertable with it, so I'm looking for cases where you have chosen something other than .NET, even though you are primarly a .NET developer.

  • Automatically Word-Wrapping Text To A Print Page?

    - by sooprise
    I have some code that prints a string, but if the string is say: "Blah blah blah"... and there are no line breaks, the text occupies a single line. I would like to be able to shape the string so it word wraps to the dimensions of the paper. private void PrintIt(){ PrintDocument document = new PrintDocument(); document.PrintPage += (sender, e) => Document_PrintText(e, inputString); document.Print(); } static private void Document_PrintText(PrintPageEventArgs e, string inputString) { e.Graphics.DrawString(inputString, new Font("Courier New", 12), Brushes.Black, 0, 0); } I suppose I could figure out the length of a character, and wrap the text manually, but if there is a built in way to do this, I'd rather do that. Thanks!
