  • How do you get the logical xor of two variables in Python?

    - by Zach Hirsch
    How do you get the logical xor of two variables in Python? For example, I have two variables that I expect to be strings. I want to test that only one of them contains a True value (is not None or the empty string): str1 = raw_input("Enter string one:") str2 = raw_input("Enter string two:") if logical_xor(str1, str2): print "ok" else: print "bad" The ^ operator seems to be bitwise, and not defined on all objects: >>> 1 ^ 1 0 >>> 2 ^ 1 3 >>> "abc" ^ "" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for ^: 'str' and 'str'

  • Choosing connectionstring in VB.NET application at startup

    - by MatsT
    I have a VB.NET application with a connection to an SQL Server 2003. On the server there are two databases, MyDatabase and MyDatabase_Test. What I would like to do is to show a dialog when the program starts that let's the user choose which database to use. My idea is to create a new form as the starup form that sets this property and then launches the main form. Currently the connectionstring is specified in the application config file. Best would be if I can specify two different connection strings in that file to choose from, but for now it is also acceptable with other solutions like hardcoding the two connectionstrings into the startup form.

  • In java getting different value for TimeZone.getDefault().getID() on different system

    - by Deepak Chaudhry
    I am getting different value for TimeZone.getDefault().getID() on different systems. For example, in case of Indian standard time, On one of the system we are getting "GMT+5:30": while on another we are getting "Asia/Calcutta". We are expected to get "Asia/calcutta" strings on all machines. Why is there an inconsistency for such behavior? Is there any way to get consistent behavior across different systems windows/MAC? What is the best way to get client time zone programmatically using Java?

  • Calling DLL functions from VB6.

    - by Tim Ring
    I've got a Windows DLL that I wrote, written in C/C++ (all exported functions are 'C'). The DLL works fine for me in VC++. I've given the DLL to another company who do all their development in VB. They seem to be having a problem linking to the functions. I haven't used VB in ten years and I don't even have it installed. What could be the problem? I've declared all my public functions as follows: define MYDCC_API __declspec(dllexport) MYDCCL_API unsigned long MYDCC_GetVer( void); . . . Any ideas? Finally got back to this today and have it working. The answers put me on the right track but I found this most helpful: http://www.codeproject.com/KB/DLL/XDllPt2.aspx Also, I had a few problems passing strings to the DLL functions, I found this helpful: http://www.flipcode.com/archives/Interfacing_Visual_Basic_And_C.shtml

  • What's the "Hello World!" of genetic algorithms good for?

    - by JohnIdol
    I found this very cool C++ sample , literally the "Hello World!" of genetic algorithms. I so decided to re-code the whole thing in C# and this is the result. Now I am asking myself: is there any practical application along the lines of generating a target string starting from a population of random strings? EDIT: my buddy on twitter just tweeted that "is useful for transcription type things such as translation. Does not have to be Monkey's". I wish I had a clue.

  • when to use strncpy or memmove

    - by robUK
    Hello, gcc 4.4.4 c89 I have always used strncpy to copy strings. I have never really used memmove or memcpy very much. However, I am just wondering when would you decide whether to use strncpy, memmove, or memcpy? The code I am writing is for a client/server application. In the documentation they use bcopy. However, could I do the same with the others? bcopy((char*)server->h_addr, (char*)&serv_addr.sin_addr.s_addr, server->h_length); Many thanks,

  • PHP float bug: PHP Hangs On Numeric Value

    - by jeroen
    I just read an interesting article about php hanging on certain float numbers, see The Register and Exploring Binary. I never explicitly use floats, I use number_format() to clean my input and display for example prices. Also, as far as I am aware, all input from for example forms are strings until I tell them otherwise so I am supposing that this problem does not affect me. Am I right, or do I need to check for example Wordpress and Squirrelmail installations on my server to see if they cast anything to float? Or better, grep all php files on my servers for float?

  • Random List of millions of elements in Python Efficiently

    - by eWizardII
    Hello, I have read this answer potentially as the best way to randomize a list of strings in Python. I'm just wondering then if that's the most efficient way to do it because I have a list of about 30 million elements via the following code: import json from sets import Set from random import shuffle a = [] for i in range(0,193): json_data = open("C:/Twitter/user/user_" + str(i) + ".json") data = json.load(json_data) for j in range(0,len(data)): a.append(data[j]['su']) new = list(Set(a)) print "Cleaned length is: " + str(len(new)) ## Take Cleaned List and Randomize it for Analysis shuffle(new) If there is a more efficient way to do it, I'd greatly appreciate any advice on how to do it. Thanks,

  • ASP.NET MVC 2 - Checkboxes

    - by Jay
    I'm using string[] roles = Roles.GetAllRoles() to get a string[] of all the ASP.NET membership roles for my application. I'm sending the roles to my view in ViewData and using a foreach to create a set of Checkboxes using <%: Html.CheckBox("RoleCheckBox") %>. There are 3 roles and my view does render 3 checkboxes. When I do a View/Source, I see the checkboxes and their corresponding hidden tags. They all have the same, so there are 6 tags with the name "RoleCheckBox" - 3 that render the checkboxes and 3 that are hidden. The problem comes when I post the form back to my controller and bind the results - something like public ActionResult Create(Person person, string[] RoleCheckBox). I get FOUR strings and I have no idea where the fourth string ("false") is coming from. I could do some testing by trying various combinations of checks to see which one (hopefully) doesn't change and ignore it but that's just ugly. Does anyone know why this would be happening? Thanks, Jay

  • JavaScript - checking for any lowercase letters in a string

    - by pcampbell
    Consider a JavaScript method that needs to check whether a given string is in all uppercase letters. The input strings are people's names. The current algorithm is to check for any lowercase letters. var check1 = "Jack Spratt"; var check2 = "BARBARA FOO-BAR"; var check3 = "JASON D'WIDGET"; var isUpper1 = HasLowercaseCharacters(check1); var isUpper2 = HasLowercaseCharacters(check2); var isUpper3 = HasLowercaseCharacters(check3); function HasLowercaseCharacters(string input) { //pattern for finding whether any lowercase alpha characters exist var allLowercase; return allLowercase.test(input); } Is a regex the best way to go here? What pattern would you use to determine whether a string has any lower case alpha characters?

  • What is the algorithm used by the memberwise equality test in .NET structs?

    - by Damian Powell
    What is the algorithm used by the memberwise equality test in .NET structs? I would like to know this so that I can use it as the basis for my own algorithm. I am trying to write a recursive memberwise equality test for arbitrary objects (in C#) for testing the logical equality of DTOs. This is considerably easier if the DTOs are structs (since ValueType.Equals does mostly the right thing) but that is not always appropriate. I would also like to override comparison of any IEnumerable objects (but not strings!) so that their contents are compared rather than their properties. This has proven to be harder than I would expect. Any hints will be greatly appreciated. I'll accept the answer that proves most useful or supplies a link to the most useful information. Thanks.

  • How many bytes does Oracle use when storing a single character?

    - by Mr-sk
    I tried to look here: http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/datatype.htm#i3253 And I understand that I have to provide string length for the column, I'm just not able to find out how many bytes oracle uses when storing a character. My limit is 500 characters, so if its 1 byte / character, I can create the column with 500, if its 2 byte / character then 1000, etc. Anyone have a link to the documentation or know for certain? In case it matters, the SQL is being called from PHP, so these are PHP strings I'm inserting into the database. Thanks.

  • Migrating shape sql to something equally powerful

    - by daRoBBie
    Hi, we are currently investigating a migration of an application that doesn't meet company standards. The application is built using VB6 and Shape SQL/Access. The application has about 120 reports by storing Shape SQL strings in a database which the user can modify using a wizard. Shape sql is not allowed at this company. We have investigated plain SQL, Linq, Entity Framework as alternatives... but all result in more complex solutions. Does anyone have another suggestion? Update: Shape SQL is an ADO command to get hierarchical datasets, for further info: http://support.microsoft.com/kb/189657

  • best way to output a full precision double into a text file

    - by flevine100
    Hi, I need to use an existing text file to store some very precise values. When read back in, the numbers essentially need to be exactly equivalent to the ones that were originally written. Now, a normal person would use a binary file... for a number of reasons, that's not possible in this case. So... do any of you have a good way of encoding a double as a string of characters (aside from increasing the precision). My first thought was to cast the double to a char[] and write out the chars. I don't think that's going to work because some of the characters are not visible, produce sounds, and even terminate strings ('\0'... I'm talkin to you!) Thoughts?

  • Identifying individual values in a text box using Flash

    - by Jamash1989
    I want to identify specific strings in a text box from user input to add to a score variable, like so - if (userWords.text == firstWord) { score = score + 1; } The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable. The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc. I am ultra confused with this problem, so thank you to anyone that may help.

  • Is there a way to define a List<> of two elements string array?

    - by Alexander Prokofyev
    I want to build two-dimentional array of strings where length of one dimention is 2. Similar to this string[,] array = new string[,] { {"a", "b"}, {"c", "d"}, {"e", "f"}, {"g", "h"} } Doing List<string[]> list = new List<string[]>(); list.Add(new string[2] {"a", "b"}); list.Add(new string[2] {"c", "d"}); list.Add(new string[2] {"e", "f"}); list.Add(new string[2] {"g", "h"}); list.ToArray(); gives me string[][] but not string[,] array. Just curious, is there some trick to build dynamically string[,] array somehow?

  • Meaning of tA tC and tP

    - by Greg Wiley
    If this is a duplicate I appoligize, but looking for two-letter strings is quite hard in any search. I'm looking for the meaning of tA tC and tP in the context of a mysql query. And in the spirit of "teaching a man how to fish" it would be great if you could point me in the right direction of where to find this info in the future. Edit: The Query $wpdb->get_row($wpdb->prepare("SELECT tA.* FROM ".AMYLITE_ADS." tA, ".AMYLITE_ADS_CAMPAIGNS." tC, ".AMYLITE_PACKAGES." tP WHERE tA.id=tC.ad_id AND tC.campaign_id=tP.campaign_id AND tP.zone_id=%d AND tP.date_end>CURDATE() GROUP BY tA.id ORDER BY RAND()", $zone->id));

  • python regex for repeating string

    - by Lars Nordin
    I am wanting to verify and then parse this string (in quotes): string = "start: c12354, c3456, 34526;" //Note that some codes begin with 'c' I would like to verify that the string starts with 'start:' and ends with ';' Afterward, I would like to have a regex parse out the strings. I tried the following python re code: regx = r"V1 OIDs: (c?[0-9]+,?)+;" reg = re.compile(regx) matched = reg.search(string) print ' matched.groups()', matched.groups() I have tried different variations but I can either get the first or the last code but not a list of all three. Or should I abandon using a regex?

  • Dynamic Like Statement in SQL

    - by Peter McElhinney
    Hey there! I've been racking my brain on how to do this for a while, and i know that some genius on this site will have the answer. Basically i'm trying to do this: SELECT column FROM table WHERE [table][column] LIKE string1 OR [table][column] LIKE string2 OR [table][column] LIKE string3... for a list of search strings stored in a column of a table. Obviously I can't do a like statement for each string by hand because i want the table to be dynamic. Any suggestions would be great. :D EDIT: I'm using MSSQL :(

  • Read a file address from a txt file using netbeans c

    Hi everybody. I`m having problems reading a file address from a txt file. The information seems to be corrupted when I watch it in the debugger. The code is FILE *parch; const char * vectorparch[50]; //array with 50 file paths parch = fopen("/home/irmay/NetBeansProjects/neurona/patrones/patrones.txt", "r"); for(j=0;j<50;j++){ fread ( vectorparch, sizeof ( char ), 50, parch ); propagar(vectorparch[j]); } fclose(parch); The file with paths has 50 strings is like this: "/home/irmay/NetBeansProjects/neurona/patrones/10_0.txt","/home/..." The function propagar is declared void propagar (const char * arch1) Thank you.

  • Loading table sections when using headers

    - by Luis Tovar
    I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

  • How to Invoke iPhone Maps for Directions with Current Location as Start Address

    - by eriaac
    Hi all. I know it's possible to start the iPhone maps application by calling openURL on a google maps URL with parameters saddr and daddr with location strings or LatLong (see ex. below), but I'm wondering if it's possible to make the start address be the "Current Location" maps bookmark so that I can use the maps app's location handling code. My Google search has been pretty fruitless. ex: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%@&daddr=%@", myLatLong, latlong]]]; Except with something to invoke the current location bookmark in place of myLatLong. Thanks!

  • Copy NSArray and replace text items with bool values

    - by Frank Martin
    I utilize a (nested) plist to populate UITableViews where users can select entries at the deepest levels and set a checkmark (or not). I want to save these selections in a same structured list where at the deepest level the NSArray contains bool values instead the text strings that are displayed in the UITableView. So how can i build from a hierarchy like the following: Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: @"Please check me" (String) a hierarchy like this? Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: 0 (NSNumber) // NSNumber for bool values I'm trying to create a deep mutable copy and replace the items at the deepest levels but have somehow the feeling that this can be done easier. Thanks for any help with this in advance. Frank
