  • 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!

  • Access DoCmd.OpenForm Not Working

    - by user961743
    Looking for a second set of eyes to figure out my problem with an Access form filter. I created a search form, when filled in, appends search criteria to a string variable (strQuery) that is put in place to the [WhereCondition] for opening a form. However, when the script is ran, nothing comes up except for a filtered form with no records. Here is the line that opens the form: DoCmd.OpenForm "ADD_NEW_NCMR", , , strQuery Before the line is ran, strQuery equals: 1=1 AND [NCMR].[NCMR_NUM] = '12-129' The form name, and table.column combination are all correct. In fact, using the DCount function returns the result of 1, which is correct for this query, and returns the correct number for other queries as well. This makes me think that there is nothing wrong with the where condition. DCount("[NCMR_NUM]", "NCMR", strQuery)

  • 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 to debug/reformat C printf calls with lots of arguments in vim?

    - by Costi
    I have a function call in a program that I'm maintaining has 28 arguments for a printf call. It's printing a lot of data in a CSV file. I have problems following finding where what goes and I have some mismatches in the parameters types. I enabled -Wall in gcc and I get warnings like: n.c:495: warning: int format, pointer arg (arg 15) n.c:495: warning: format argument is not a pointer (arg 16) n.c:495: warning: double format, pointer arg (arg 23) The function is like this: fprintf (ConvFilePtr, "\"FORMAT3\"%s%04d%s%04d%s%s%s%d%s%c%s%d%c%s%s%s%s%s%s%s%11.lf%s%11.lf%s%11.lf%s%d\n", some_28_arguments_go_here); I would like to know if there is a vim plugin that highlights the printf format specifier when i go with the cursor over a variable. Other solutions? How to better reformat the code to make it more readable?

  • Sqlite3 Database versus populating Arrays

    - by Kenoy
    hi, I am working on a program that requires me to input values for 12 objects, each with 4 arrays, each with 100 values. (4800) values. The 4 arrays represent possible outcomes based on 2 boolean values... i.e. YY, YN, NN, NY and the 100 values to the array are what I want to extract based on another inputted variable. I previously have all possible outcomes in a csv file, and have imported these into sqlite where I can query then for the value using sql. However, It has been suggested to me that sqlite database is not the way to go, and instead I should populate using arrays hardcoded. Which would be better during run time and for memory management?

  • regex pattern to match only strings that don't contain spaces PHP

    - by Jamex
    Hi, I want to match the word/pattern that is contained in the variable, but only match against the words that don't have white spaces. Please give suggestions. $var = 'look'; $array = ('look', 'greatlook', 'lookgreat', 'look great', 'badlook', 'look bad', 'look ', ' look'); matches words: look, greatlook, lookgreat, badlook non matches: look great, bad look, look (trailing space(s)), (space(s)) look. The syntax of the below functions are OK, but it matches everything $match = preg_grep ("/$var/", $array); $match = preg_grep ("/^$var/", $array); (match words with 'look' at the start) but when I include the [^\s], it gives an error $match = preg_grep ("/$var[^\s]/", $array); Parse error: syntax error, unexpected '^', expecting T_STRING or T_VARIABLE TIA

  • Why isn't the "this." command needed in this constructor? (java)

    - by David
    I'm reading a book about java. It just got to explaining how you create a class called "deck" which contains an array of cards as its instance variable(s). Here is the code snippit: class Deck { Card[] cards; public Deck (int n) { cards = new Card[n]; } } why isn't the this. command used? for example why isn't the code this: class Deck { Card[[] cards; public Deck (int n) { this.cards = new Card[n]; } }

  • 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'??

  • Why is HttpContext.Current.Session available in HttpModule but not in Response.Filter?

    - by Abtin Forouzandeh
    I have written an HttpModule that adds a response filter. The filter is capturing page output and storing it in a session variable. I am able to access HttpContext.Current.Session in my HttpModule. The HttpModule is handling the PostAcquireRequestState event. I am still able to access HttpContext.Current.Session in the PostAcquireRequestState event. I am adding a custom stream that inherits from Stream to Response.Filter HttpContext.Current.Session is null when accessed from the Stream.Write method. Everything worked fine when using an InProc SessionState. However, I now must use StateServer. Using StateServer, the code is now broken. Any ideas?

  • PHP: passing GET between multiple pages

    - by aterimperator
    I'm building a set of pages where I have a number of GET variables and it is often valuable to keep passing it along to the next page. This leads to ugly code where I have to have "if this $_GET variable is set, dynamically add it to this hyperlink". This is, in many senses, not a problem; but I had the thought "there must be a better way to do this", I mean after all basically all I want is to take the '?' and everything after it and append it to the links on that page, it would seem this should be rather simple (or at least possible to do in a for loop). I tried google searching but couldn't find anything, so I figured I'd see if any of you happen to know. Why not use SESSION? Because these pages need to be capable of being bookmarked. Thank you.

  • 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.

  • 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?

  • 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.

  • K&R Exercise 1-21 - Mental incomprehension.

    - by asdfg
    The "impossible" K&R exercise. "Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops, say every n columns. Should n be a variable or a symbolic parameter?" The problem I'm having is, I'm unsure about how to even do this correctly. I know it's not very explanatory, but that's pretty much the problem here. Most of the examples I've seen have counted a number of blanks, and replaced those series with a tab, but this isn't what its asking, I reckon I understand what its asking, but currently feel unable to do this. Could anyone help :)

  • 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.

  • How to read in a negative double with scanf() in C

    - by rize
    I'm learning basics of C and writing a simple first order equation solver. I want the input to be exactly ax+b=c or ax-b=c, where a, b, c are double type. I'm employing scanf() to read in user input and to check if it's of the correct form. However, if I enter a negative double, -4.6 say, as the "a" in the equation, scanf() won't read the a,b,c correctly. I'm using %lf inside scanf(). How do I read a negative double, then? Many thanks. My code: if (scanf("%lfx+%lf=%lf", &a, &b, &c)) more code If I use as the input "-6.2x+3.4=-5.9", the value 3.4 will be assinged to variable a, while b and c remain as they were and "more code" is run.

  • Using Qt with custom MinGW

    - by ereOn
    Hi, I don't know if this question would fit better on superuser.com, but since it's rather compiler related, I give it a try here. I have to use Qt with a specific version of gcc (4.5). I downloaded the last official Qt release for Windows (Vista, 32 bits version) and didn't install the shipped MinGW version; I just installed the Qt libraries/binaries. In a console, when I type qmake && make, make fails, complaining that 'g++' is not recognized as an internal command. If I type g++ in the same console, I however have the following output: g++: no input files So g++ is definitely recognized. For those who may ask, both the Qt binaries directory and MinGW binaries directory are in the system PATH environment variable. What could be wrong here ?

  • Using SHIFT_JIS text in PHP

    - by Joe Corkery
    I am building a form that needs to accept characters encoded in SHIFT_JIS and then send those results via email to a recipient. I've tried to simply capture the results from the $_POST variable and then to insert them into a block of text like this: $contents = <<<TEST Name: $NameJp ... TEST but that doesn't appear to work (which doesn't really surprise me). This is my first attempt at dealing with non-ASCII characters in PHP and I am hoping that people might have some suggestions. Perhaps I am missing a simple function to encode the text. Also, are there any other potential pitfalls that I might encounter? Thanks.
