  • Can't return a String value and append it...why?

    - by squeezemylime
    I am writing an app and am having problems returning a simple string value, and I'm not sure why. The function I am using (within a file called APIManager.m) is: - (NSString*) returnVenueUrl { NSString *venueUrl = [devEnvironment stringByAppendingString:@"venue/id/"]; return venueUrl; } I can return this properly by doing this in another .m file: APIManager *apiManager = [APIManager apiManager]; NSLog(@"view venue URL is here: %@", [apiManager returnVenueUrl]); But when I go to append a variable cast as a String onto it, I get nothing.. venueURL = [apiManager returnVenueUrl]; venueURL = [venueURL stringByAppendingString:venueId]; NSLog(@"the Full Venue URL is: %", venueURL); If anyone has any advice on how to fix this, it would be much appreciated!

  • Force Python to be 32 bit on OS X Lion

    - by sciencectn
    I'm trying to use CPLEX within Python on Mac OS 10.7.5. CPLEX appears to only support a 32 bit python. I'm using this in a python shell to check if it's 32 bit: import sys,platform; print platform.architecture()[0], sys.maxsize > 2**32 I've tried these 2 commands as suggested in man 1 python, but neither seem to force 32 bit: export VERSIONER_PYTHON_PREFER_32_BIT=yes defaults write com.apple.versioner.python Prefer-32-Bit -bool yes The only thing that seems to work is this: arch -i386 python However, if I run a script using arch which calls other scripts, they all seem to start up in 64 bit mode. Is there another system wide variable to force it into 32 bit mode?

  • Sql inline query with parameters. Parameter is not read when the query is executed.

    - by fzshah76
    Hi All: I am having a problem with my sql query in c#, basically it's inline query with parameters, but when I run it it tells me that parameter 1 or parameter 2 is not there here is my query declared on top of the page as public: public const string InsertStmtUsersTable = "insert into Users (username, password, email, userTypeID, memberID, CM7Register) " + "Values(@username, @password, @email, @userTypeID, @memberID,@CM7Register ); select @@identity"; this is my code for assigning the parameters, I know I am having problem so I am assigning the params twice: Username =(cmd.Parameters["@username"].Value = row["username"].ToString()) as string; cmd.Parameters["@username"].Value = row["username"].ToString(); In 1 methopd it calls this query and tries to insert to table, here is the code: Result = Convert.ToInt32(SqlHelper.ExecuteScalar(con, CommandType.Text,InsertStmtUsersTable)); Exact error message is: Must declare the variable '@username'.

  • How to determine what user and group a Python script is running as?

    - by Chirael
    I have a CGI script that is getting an "IOError: [Errno 13] Permission denied" error in the stack trace in the web server's error log. As part of debugging this problem, I'd like to add a little bit of code to the script to print the user and (especially) group that the script is running as, into the error log (presumably STDERR). I know I can just print the values to sys.stderr, but how do I figure out what user and group the script is running as? (I'm particularly interested in the group, so the $USER environment variable won't help; the CGI script has the setgid bit set so it should be running as group "list" instead of the web server's "www-data" - but I need code to see if that's actually happening.)

  • FOR XML PATH Query results to file with SSIS

    - by whimsql
    In SSMS I've gotten my for xml path query written and it's beautiful. I put it in an "Execute SQL Task" in the Control Flow, set the resultset to XML. Now how to I get the results into an actual xml file that I can turn around and FTP to a third party? This should have been so easy! I would put the XML into a variable but we are looking at a HUGE file, possibly 100mb+ Do I need to use a Script Task? (I'd like to avoid that if there is another option.)

  • Programmatically Detecting Valid Style Properties In Flex

    - by Joshua
    If I want to know if an object has a particular property I can code this: if (SomeObject.hasOwnProperty('xyz')) { // some code } But some styles masquerade as properties at design time such as Button.color... How can I know what style properties are valid at runtime? ie: What is the equivalent of hasOwnProperty for getStyle/setStyle? In other words how can I know if an object HAS A particular style variable... When I write: MyButton.setStyle('qsfgaeWT','-33'); It won't accomplish anything, but it also doesn't error. How can I know programmatically that 'qsfgaeWT' is NOT a valid style of 'Button'??

  • Can you explain what's going on in this Ruby code?

    - by samoz
    I'm trying to learn Ruby as well as Ruby on Rails right now. I'm following along with Learning Rails, 1st edition, but I'm having a hard time understanding some of the code. I generally do work in C, C++, or Java, so Ruby is a pretty big change for me. I'm currently stumped with the following block of code for a database migrator: def self.up create_table :entries do |t| t.string :name t.timestamps end end Where is the t variable coming from? What does it actually represent? Is it sort of like the 'i' in a for(i=0;i<5;i++) statement? Also, where is the :entries being defined at? (entries is the name of my controller, but how does this function know about that?)

  • problem with hierarchical clustering in Python

    - by user248237
    I am doing a hierarchical clustering a 2 dimensional matrix by correlation distance metric (i.e. 1 - Pearson correlation). My code is the following (the data is in a variable called "data"): from hcluster import * Y = pdist(data, 'correlation') cluster_type = 'average' Z = linkage(Y, cluster_type) dendrogram(Z) The error I get is: ValueError: Linkage 'Z' contains negative distances. What causes this error? The matrix "data" that I use is simply: [[ 156.651968 2345.168618] [ 158.089968 2032.840106] [ 207.996413 2786.779081] [ 151.885804 2286.70533 ] [ 154.33665 1967.74431 ] [ 150.060182 1931.991169] [ 133.800787 1978.539644] [ 112.743217 1478.903191] [ 125.388905 1422.3247 ]] I don't see how pdist could ever produce negative numbers when taking 1 - pearson correlation. Any ideas on this? thank you.

  • stting environment variables in powershell by calling python script that prints $env:myVar=myvalue

    - by leeg
    I have some legacy python scripts that manage my shell environment for all the programs and plugins I am running on Linux (bash) and windows (cmd.exe). I want to port this to powershell. How do I set environment variables in powershell by calling python script that prints $env:myVar=myvalue and causes my environment variable to persist in the powershell. In Bash I can use a bash function to call my python script which prints export var=value to stdout and the function will set the environment variables in my shell. This will also work in windows cmd shell by calling a .bat file. I cannot figure out how to do this in powershell. I think it should be something like this: setvar.ps1: function SETVAR {c:\python26\python.exe varconfig.py } varconfig.py: import sys print >> sys.stdout, '$env:myVar=foo'

  • converting string to int in C++

    - by xbonez
    I am trying to convert a string I read in from a file to an int value so I can store it in an integer variable. This is what my code looks like: ifstream sin; sin.open("movie_output.txt"); string line; getline(sin,line); myMovie.setYear(atoi(line)); Over here, setYear is a mutator in the Movie class (myMovie is an object of Movie class) that looks like this: void Movie::setYear(unsigned int year) { year_ = year; } When I run the code, I get the following error: error C2664: 'atoi' : cannot convert parameter 1 from 'std::string' to 'const char *' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

  • How to set the bounce address using System.Net.Mail?

    - by Anthony
    I'm trying to implement the Variable envelope return path (VERP) method to manage email addresses (ie when an email I send bounces back I want it to be sent to a specific email address so that I can update my database to avoid sending emails to that email address in the future). According to this article it is possible to specify the email address a bounce email is sent to. How do you do this in .Net? For example say I ([email protected]) want to send an email to you ([email protected]). If [email protected] doesn't exist anymore I want yourserver to send the bounce email to [email protected]). This way when I receive this bounced email I know that [email protected] is not a valid email address anymore and I can update my database accordingly. In this example, the bounce address would be: [email protected] How do you specify it using System.Net.Mail?

  • XQuery fn:replace not behaving as expected

    - by CoolGravatar
    I have an Excel worksheet in XML format which contains <Cell ss:StyleID="s127"><Data ss:Type="String">A01-Replace</Data></Cell> I want to replace @A01-Replace with a different string. I'm using the XQuery's replace function like so: let $excel := doc("excel.xml") let $test := "another string" return replace($excel, "(A[0-9]+-Replace)", $test) Before calling replace, the variable $excel is valid XML upon output. However, when I output $excel after I call the replace function, all of the XML tags have been stripped, and $excel is a string with the content of the cells as its values. I would like to keep the XML tags there. Any ideas?

  • slicing 2d numpy array

    - by MedicalMath
    I have a 2d numpy array called FilteredOutput that has 2 columns and 10001 rows, though the number of rows is a variable. I am trying to take the 2nd column of FilteredOutput and use it to populate a new 1d numpy array called timeSeriesArray using the following line of code: timeSeriesArray=p.array(FilteredOutput[:,0]) I got this syntax from the following link. But the problem is that I am getting the following error message: TypeError: list indices must be integers, not tuple Can anyone show me the proper syntax for populating the 1d array timeSeriesArray with the contents of the second column of the 2d array FilteredOutput?

  • Get jQuery Error if PHP Breaks

    - by Norbert
    I have a PHP script that breaks if a variable is not populated and it isn't added to the database, but jQuery handles this as a success and I get this error: TypeError: Result of expression 'data' [null] is not an object. Here's the jQuery script: $.ajax({ type: "POST", url: "/clase/do-add", data: $("#adauga").serialize(), dataType: "json", error: function (xhr, textStatus, errorThrown) { alert('Try again.'); }, success: function(data) { var dlHTML = '<dl id="' + data.id + '"> [too long] </dl>'; $('form#adauga').after(dlHTML); $('#main dl:first').hide().fadeIn(); adaugaClasaSubmit.removeAttr('disabled'); adaugaClasa.removeAttr('readonly'); adaugaClasa.val("").focus(); } });

What happens when a give them all a float: left value, I get something like this: ######### ######### # box 1 # # box 2 # ######### # ..... # ......... # ..... # ......... ######### ######### ######### # box 3 # # box 4 # # ..... # # ..... # ######### ######### ######### ######### # box 5 # # box 6 # # ..... # ######### # ..... # ######### (The periods are white space) What I really would really like is the top of box 3 to touch the bottom of box 1. Any easy way to acheive this?

  • Specify only the second parameter in a javascript function

    - by Ben McCormack
    The spec for the jQuery ajax.error function is: error(XMLHttpRequest, textStatus, errorThrown)Function I'm trying to catch the error and display the textStatus, but I can't figure out how to specify only the textStatus without having to put in a variable name for XMLHttpRequest and errorThrown. My code currently looks like this: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: hbAddressValidation.webServiceUrl, data: this.jsonRequest, dataType: "json", timeout: 5, success: function (msgd) { //... }, error: function (a,textStatus,b) { $("#txtAjaxError").val("There was an error in the AJAX call: " + textStatus); } }); You can see in my code that I'm putting variables a and b as placeholders for the first and last variables in the error function. I know that in my success function, I'm only providing one parameter and it works fine, but in that case data is the first parameter. In the case of error, textStatus is the second parameter, but that's the only one I want to specify. Is this possible?

  • JS 2 minute countdown then execute a function?

    - by Cyprus106
    I'm not that great at Javascript, for the record! I DO know how to use ajax. I just need a bit of help. I'm having a hard time figuring out how to display a 5 minute countdown, and once the countdown hits zero, to run a function. I need to pass a variable to the function that needs to run. I tried SetInterval but this isn't exactly my strong suit. Does anyone have any suggestions? I can post the code I've got, but I would equate it to a gorilla fumbling in the dark at a typewriter!

  • how much concurrent http request can erlang handle

    - by user209123
    I am developing a application for benchmarking purposes, for which I require to create large number of http connection in a short time, I created a program in java to test how much threads is java able to create, it turns out in my 2GB single core machine, the limit is variable between 5000 and 6000 with 1 GB of memory given to JVM after which it hits outofmemoryerror with heap limit reached. It is suggested around that erlang will be able to generate much more concurrent processes, I am willing to learn erlang if it is capable of solving the problem , although I am interested in knowing can erlang be able to say generate somewhere around 100000 processes which are essentially http requests waiting for responses, in a matter of few seconds without reaching any limit like memory error etc.,

  • Posting null values via AJAX

    - by nickf
    Using the jQuery $.post function, if you send a null value, it arrives at the server side as "null". Example: Javascript: $.post('test.php', { foo : null }); PHP: var_dump($_POST['foo']); // string(4) "null" I understand why this is so, but was wondering the best way to work around the limitation? Should you: Loop through all the variables in JS before you send them and replace with an empty string? Interpret "null" as null on the server side? Don't send the variable at all? Something else?

  • How do I get python to load .NET .dlls referenced by mixed mode .dlls?

    - by Michael Kelley
    I have a python .pyd that is a mixed mode C++ DLL. The DLL loads fine and loads unmanaged C++ dlls without a problem, but when it tries to load the .NET dlls referenced by the managed C++ dlls it fails with this error message: Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly '...' Copying these .NET dlls to the directory that pythod_d.exe is contained in allows the .NET libraries to load successfully, but this is not a good long term solution. Is there an environment variable I have to set or some command line option to python_d.exe that will solve my problem? Note that using IronPython or Python .NET is NOT acceptable.

  • Documenting preprocessor defines in Doxygen

    - by Fire Lancer
    Is it possible to document preprocessor defines in Doxygen? I expected to be able to do it just like a variable or function, however the Doxygen output appears to have "lost" the documentation for the define, and does not contain the define its self either. I tried the following /**My Preprocessor Macro.*/ #define TEST_DEFINE(x) (x*x) and /**@def TEST_DEFINE My Preprocessor Macro. */ #define TEST_DEFINE(x) (x*x) I also tried putting them within a group (tried defgroup, addtogroup and ingroup) rather than just at the "file scope" however that had no effect either (although other items in the group were documented as intended). I looked through the various Doxygen options, but couldn't see anything that would enable (or prevent) the documentation of defines.
