  • Execution sequence inside a jquery event handler

    - by user576358
    I have a big issue with the execution squence inside this jquery handler : Was wondering if anyone has come accross this before: I have a simple form: <form action='foo.cgi' id='myForm' > <input type=text name='name' /> <input type=submit value='Find it!'/> </form> when user clicks on Find it! would like to change the cursor to 'progress' before the data is returned through an ajax call: $(document).ready(function(){ $("#myForm ").submit(function(){ $("body").css("cursor", "progress") ; htmlobj=$.ajax({url:server_url,..........); } } However: The cursor [line 2 above ] does not change until data is returned through ajax - Seems like line 3. gets executed before 2. Any help is greatly appreciated

  • Bash intercepting wildcard in script

    - by MrRoth
    I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

  • Understanding c++ block of code

    - by kotoko
    I was given a c++ main and have to code it so it works. I am having some trouble understanding the code as I am a bit new to cpp. Here is the code int main(int argc, char *argv[]) { Class::setAtribute("string"); Class(Class::CONSTANT) << "starting up..."; } Some questions: How can the first line work with no variables? Is it static? The second line is really strange for me, what I can make out is a Constructor that takes in a class constante and then prints it out somehow? If someone could explain me this bit of code it would be great! Thanks in advance.

  • Python: Check if all dictionaries in list are empty

    - by Brant
    I have a list of dictionaries. I need to check if all the dictionaries in that list are empty. I am looking for a simple statement that will do it in one line. Is there a single line way to do the following (not including the print)? l = [{},{},{}] # this list is generated elsewhere... all_empty = True for i in l: if i: all_empty = False print all_empty Somewhat new to python... I don't know if there is a shorthand built-in way to check this. Thanks in advance.

  • Why are some strings displayed as garbage when I scroll my read-only multiline Win32 edit control ve

    - by sharptooth
    In my native C+ Win32 GUI application I have a property sheet with two property pages. One of the property pages contains an edit box: EDITTEXT IDC_EDIT_ID,x,y,width,height,ES_MULTILINE | ES_READONLY | NOT WS_BORDER | WS_VSCROLL | WS_HSCROLL | NOT WS_TABSTOP,WS_EX_STATICEDGE I set a multiline text to this edit box. The text has more lines than the edit can fit, so some of the text is clipped and a vertical scroll bar appears. When I scroll up with the mouse the lines that come "from under clip area" are drawn as garbage - it looks like first one line is drawn, then some other line is drawn on the same place without first painting the background. The lines that just move up - ones that were visible before scrolling and remain visible after scrolling are displayed allright. What's the reason and workaround for this behavior?

  • Using ManagementClass.Getinstances() from IronPython

    - by Leo Bontemps
    I have an IronPython script that looks for current running processes using WMI. The code looks like this: import clr clr.AddReference('System.Management') from System.Management import ManagementClass from System import Array mc = ManagementClass('Win32_Processes') procs = mc.GetInstances() That last line where I call the GetInstances() method raises the following error: Traceback (most recent call first): File "<stdin>", line 1, in <module> SystemError: Not Found I am not understanding what's not being found?!? I believe that I may need to pass an instance of ManagementOperationObserver and of EnumerationOptions to GetInstance() however, I don't understand why that is, since the method with the signature Getinstance() is available in ManagementClass.

  • I can't find a DirectX installer to run from my installer.

    - by John
    I tried this one. But it's the annoying one which asks you where to extract temp files, my users won't know what this means. I also tried the web installer, but you're not strictly allowed to use this. I don't really follow the windows setup stuff, but is there a single .EXE I am allowed to distribute and run, which just works (for DX 9.0C) with some command-line args? Or some other way, which can can described in idiot-proof steps and and called in one command-line argument from an installer script like Inno?

    I am using the following code for reading lines from a text-file. What is the best method for handling the case where the line is greater than the limit SIZE_MAX_LINE? void TextFileReader::read(string inFilename) { ifstream xInFile(inFilename.c_str()); if(!xInFile){ return; } char acLine[SIZE_MAX_LINE + 1]; while(xInFile){ xInFile.getline(acLine, SIZE_MAX_LINE); if(xInFile){ m_sStream.append(acLine); //Appending read line to string } } xInFile.close(); }

  • parsing position files in ruby

    - by john
    I have a sample position file like below. 789754654 COLORA SOMETHING1 19370119FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 20060722FYY076 2342342342SDFSD3423 I am interested in positions 54-61 (4th column). I want to change the date to be a different format. So final outcome will be: 789754654 COLORA SOMETHING1 01191937FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 07222006FYY076 2342342342SDFSD3423 The columns are seperated by spaces not tabs. And the final file should have exact number of spaces as the original file....only thing changing should be the date format. How can I do this? I wrote a script but it will lose the original spaces and positioning will be messed up. file.each_line do |line| dob = line.split(" ") puts dob[3] #got the date. change its format 5.times { puts "**" } end Can anyone suggest a better strategy so that positioning in the original file remains the same?

  • Creating a PHP web page that enables you to reboot the server in Linux?

    - by Stuart
    I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

  • How to port C# code which uses a callback to VB.NET?

    - by Bob
    I need to port the following from the ASP.NET MVC 2 sourcecode from C# to VB.NET. It's from AuthorizeAttribute.cs beginning on line 86: HttpCachePolicyBase cachePolicy = filterContext.HttpContext.Response.Cache; cachePolicy.SetProxyMaxAge(new TimeSpan(0)); cachePolicy.AddValidationCallback(CacheValidateHandler, null /* data */); where CacheValidateHandler is: private void CacheValidateHandler(HttpContext context, object data, ref HttpValidationStatus validationStatus) { validationStatus = OnCacheAuthorization(new HttpContextWrapper(context)); } The VB.NET port from http://converter.telerik.com doesn't quite work for this line: cachePolicy.AddValidationCallback(CacheValidateHandler, Nothing) ' Error where CacheValidateHandler is: Private Sub CacheValidateHandler(ByVal context As HttpContext, ByVal data As Object, _ ByRef validationStatus As HttpValidationStatus) validationStatus = OnCacheAuthorization(New HttpContextWrapper(context)) End Sub VS2008 complains that CacheValidateHandler does not specify its arguments for context, data, and validationStatus. Any ideas how to port this code?

  • Firing events in script task

    - by Anonymouslemming
    I've got an SSIS project where I am constructing an SQL command based on some variables. I'm constructing the command in a script task, and want to output the constructed SQL to the 'Execution Results' window. I am trying to do this using a FireInformation line from inside my script as follows: Dts.Events.FireInformation(99, "test", "Make this event appear!", "", 0, true); However, in the script editor when editing ScriptMain.cs, that line is underlined in red, and on mouseover, I get the following message: Error: The best overloaded method match for 'Microsoft.SqlServer.Dts.Tasks.ScriptTask.EventsObjectWrapper.FireInformation(int, string, string, string, int, ref bool') has some invalid arguments As a result, my script does not compile and I cannot execute it. Any idea what I'm doing wrong here, or what I need to change to be able to see the values of my variables at this point in the Execution output?

    - by Vipul
    I need to open a new pop up window on click of a button in a view. The new window should be redirect to a specific actionmethod in a specific controller. I also need to provide attributes for size of the new pop up window. I have been trying the following code: <input type="button" name = "ClickMe" Value="ClickMe" onclick= "javascript:window.open('/Home/Create/','Customer Search',height='window.screen.height - 100', width='200',left='window.screen.width - 250' ,top='10',status='no',toobar='no',resizable='yes',scrollbars='yes')"/> On click of button, nothing happens.

  • Modify input stream data on the fly

    - by Frizi
    I would like to implement a std::stream modifier/parser, that is doing data manipulation on the fly. Is it possible to create it in form of stream manipulator? For example, i want to strip all the line comments (from any // to the end of line) out of the stdin and pass it to stdout. string str; istream strippingCin = cin >> stripcomments; while(strippingCin.good()) { strippingCin >> str; cout << str; } There may be also a large file input instead of cin, so i don't want to load full stream data into memory at once. Is it possible without writing my own stream class? Maybe is there another route i should take instead?

  • MySqlConnection really not close

    - by stighy
    Hi guys, i've a huge problem. Take a look to this sample code private sub FUNCTION1() dim conn as new mysqlconnection(myconnstring) conn.open ---- do something FUNCTION2() ---- conn.close end sub private sub FUNCTION2() dim conn as new mysqlconnection(myconnstring) .... conn.open -- do something conn.close end sub Despite i close regulary all my connection, they remains "open" on the mysql server. I know this because i'm using MySQL Administration tool to check how many connection i open "line by line" of my source code. In fact i get a lot of time "user has exceeded the 'max_user_connections' resource (current value: 5)" My hoster permit ONLY 5 connection, but i think that if i write GOOD source code, this cannot be a problem. So my question is: why that "damn" connections remain open ?? Thank you in advance!

  • C++ STL: Trouble with string iterators

    - by Rosarch
    I'm making a simple command line Hangman game. void Hangman::printStatus() { cout << "Lives remaining: " << livesRemaining << endl; cout << getFormattedAnswer() << endl; } string Hangman::getFormattedAnswer() { return getFormattedAnswerFrom(correctAnswer.begin(), correctAnswer.end()); } string Hangman::getFormattedAnswerFrom(string::const_iterator begin, string::const_iterator end) { return begin == end? "" : displayChar(*begin) + getFormattedAnswerFrom(++begin, end); } char Hangman::displayChar(const char c) { return c; } (Eventually, I'll change this so displayChar() displays a - or a character if the user has guessed it, but for simplicity now I'm just returning everything.) When I build and run this from VS 2010, I get a popup box: Debug Assertion Failed! xstring Line: 78 Expression: string iterator not dereferenceable What am I doing wrong?

  • Numeric GUI bottleneck

    - by Physic
    Hi all, I've made a GUI to set up and start a numerical integrator using PyQT4, Wing, QT, and Python 2.6.6, on my Mac. The thing is, when I run the integrator form the GUI, it takes very many times longer than when I crudely run the integrator from the command line. As an example, a 1000 year integration took 98 seconds on the command line and ~570 seconds from the GUI. In the GUI, the integration runs from a thread and then returns. It uses a a queue to communicate back to the GUI. Does anyone have any ideas as to where the bottleneck is? I suspect that others may be experiencing something like this just on a smaller scale. t = threading.Thread( target=self.threadsafe_start_thread, args=( self.queue, self.selected ) ) t.start() Thanks!
