  • C++'s unordered_map / hash_map / Google's dense_hash - how to input binary data (buf+len) and insert

    - by shlomif
    Hi all, I have two questions about Google's dense_hash_map, which can be used instead of the more standard unordered_map or hash_map: How do I use an arbitrary binary data memory segment as a key: I want a buffer+length pair, which may still contain some NUL (\0) characters. I can see how I use a NUL-terminated char * string , but that's not what I want. How do I implement an operation where I look if a key exists, and if not - insert it and if it does return the pointer to the existing key and let me know what actually happened. I'd appreciate it if anyone can shed any light on this subject. Regards, -- Shlomi Fish

  • check for several conditions when a user logs in

    - by paul
    I would like to accomplish the following: If a username or password field is null, notify the user. If user name already exists, do not insert into the database and notify user to create a different name. if the username is unique and password is not null, return the username to the user. As of now it always returns "Please enter a different user name." I believe the issue has to do with the database query but I am not sure. If anyone can have a look and see if I am making an error, I greatly appreciate it, thanks. if ($userName or $userPassword = null) { echo "Please enter a user name and password or return to the homepage."; } elseif (mysql_num_rows(mysql_query("SELECT count(userName) FROM logininfo WHERE userName = '$userName'")) ==1) { echo "Please enter a different user name."; } elseif ($userName and $userPassword != null) { echo "Your login name is: $userName"; }

  • In Python, are there builtin functions for elementwise boolean operators over boolean lists?

    - by bshanks
    For example, if you have n lists of bools of the same length, then elementwise boolean AND should return another list of that length that has True in those positions where all the input lists have True, and False everywhere else. It's pretty easy to write, i just would prefer to use a builtin if one exists (for the sake of standardization/readability). Here's an implementation of elementwise AND: def eAnd(*args): return [all(tuple) for tuple in zip(*args)] example usage: >>> eAnd([True, False, True, False, True], [True, True, False, False, True], [True, True, False, False, True]) [True, False, False, False, True] thx

  • Resize Report to set on one page by wide

    - by adopilot
    Is there a possibility to set size of Report to fit on one page pragmatically. In excel there is option for page Scaling where We can set how many pages by tall and by wide is going to be printed . Does exists something analog in SSRS2008 ? I am using Sql Report Server 2008 and Ill try to do that by exporting report to excel and after that to set numbers of pages using ASP and C#. But the bad thing that I do not have office system installed on my server, and If I deploy code over visual studio project for Excel worksheet I am afraid that is not going to work on my server. Subquestion Are there any .NET library for Excel which implement the needed function for page scaling that can work without Office installed on target server.

  • How do I determine the video file size on youtube in Java?

    - by user1753343
    I am using the youtube-API to gather different information about videos. The only missing attribute until now is size. The API itself doesn't provide any functionality. I googled, but didn't found any solution. Indirect way My next idea was to get the path to the video-file itself and make a get-request. In the response-headers I could check for the file size. So I searched for "video / download / youtube / java". Some time ago youtube used get_video_info but this doesn't work today. I also found an application called JavaYoutubeDownloader but it seems VERY complicated for just getting the file size and it doesn't work either (just prints finish, without downloading anything). So is there a way to get the filesize of a video on youtube by using Java? If not, what would be a practical solution for this problem (a list of video_ids exists)?

  • what is the underlying data structure of a set c++?

    - by zebraman
    I would like to know how a set is implemented in C++. If I were to implement my own set container without using the STL provided container, what would be the best way to go about this task? I understand STL sets are based on the abstract data structure of a binary search tree. So what is the underlying data structure? An array? Also, how does insert() work for a set? How does the set check whether an element already exists in it? I read on wikipedia that another way to implement a set is with a hash table. How would this work?

  • Shell script syntax error: unexpected end of line

    - by user1557674
    I wrote a simple shell script to check for the existence of a xml file and if it exists, then rename an old xml file to be backup and then move the new xml file to where the old xml file was stored. #!/bin/sh oldFile="/Documents/sampleFolder/sampleFile.xml" newFile="/Documents/sampleFile.xml" backupFileName="/Documents/sampleFolder/sampleFile2.backup" oldFileLocation="/Documents/sampleFolder" if [ -f "$newFile" ] ; then echo "File found" #Rename old file mv $oldFile $backupFileName #move new file to old file's location mv $newFile $oldFileLocation else echo "File not found, do nothing" fi However, every time I try to run the script, I get 4 command not found messages and a syntax error: unexpected end of file. Any suggestions on why I get these command not found errors or the unexpected end of file? I double checked that I closed all my double quotes, I have code highlight :) EDIT: output from running script: : command not found: : command not found: : command not found1: : command not found6: replaceXML.sh: line 26: syntax error: unexpected end of file

  • C# Closing a form during a constructor

    - by pm_2
    Is it possible to close a form while the constructor is executing (or simply to stop it showing at this stage)? I have the following code: public partial class MyForm : Form { public MyForm() { if (MyFunc()) { this.Close(); } } } Which errors in Main(), here: static void Main() { ... // Following line errors Application.Run(new MyForm()); } I’ve tried checking the result of MyForm like this: static void Main() { ... MyForm frm = new MyForm(); if (frm != null) { // Following line errors Application.Run(frm); } } But that doesn’t seem to help. Can anyone tell me a way around this, please? Maybe a way to check the form to see if it still exists?

  • Design guide-lines for writing a Typed SQL Statement API ?

    - by this. __curious_geek
    Last night I came up to sometihng intersting while designing my new project that brought me to ask this qustion here. My project is supposed to follow Table Gateway pattern using tradional ADO.Net datasets for data access. I don't want to write plain queries in my data-access classes. So I came up with an idea of writing a parser kindaa api that exposes objects and methods to generate queries on the move based on my domain objects. Later I want this api to hook up to my Business objects and provide Typed SQL generator api right on the business object instances. Any idea or references how can I do this ? This seems very wide to start with that I'm compelled take your opinions here. Does there anything already exists that can do this ?

  • Running script constantly in background: daemon, lock file with crontab, or simply loop?

    - by Mauritz Hansen
    I have a Perl script that queries a database for a list of files to process processes the files and then exits Upon startup this script creates a file (let's say script.lock), and upon exit it removes this file. I have a crontab entry that runs this script every minute. If the lockfile exists then the script exits, assuming that another instance of itself is running. The above process works fine but I am not very happy with the robustness of this approach. Specifically, if for some reason the script exits prematurely and the lockfile is not removed then a new instance will not execute properly. I would appreciate some advice on the following: Is using the lock file a good approach or is there a better/more robust way to do this? Is using crontab for this a good idea or could I better write an endless loop with sleep()? Should I use the GNU 'daemon' program or the Perl Proc::Daemon module (or some other equivalent) for this?

  • file_get_contents returns an empty string that is 354 bytes long.

    - by Kendall Crouch
    I'm trying to read the contents of a file and simply getting an empty string. The file exists on the server. I've tried some test with the following code and get the true to display: $filename = "includes/blah.php"; $filecontents = file_get_contents($filename, FILE_USE_INCLUDE_PATH); if ($filecontents === false) { echo(":FALSE:"); } else { echo(":TRUE:"); } var_dump($filecontents); The dump displays "string(354)" which is the correct size of the file. What am I doing wrong?

  • Are compound command's second and subsequent lines not effected by HISTCONTROL in bash?

    - by UniMouS
    When consulting bash's man page, it read this sentence about bash history: The second and subsequent lines of a multi-line compound command are not tested, and are added to the history regardless of the value of HISTCONTROL. But I have tried this: $ HISTCONTROL=ignorespace $ if [ -f /var/log/messages ] > then > echo "/var/log/message exists." > fi $ history | tail -2 18 HISTCONTROL=ignorespace 19 history | tail -2 Note that the if is leaded by a space. Why the second line of this if compound command still not appear in the history?

  • What is a simple C library for a set of integer sets?

    - by conradlee
    I've got to modify a C program and I need to include a set of unsigned integer sets. That is, I have millions of sets of integers (each of these integer sets contains between 3 and 100 integers), and I need to store these in some structure, lets call it the directory, that can in logarithmic time tell me whether a given integer set already exists in the directory. The only operations that need to be defined on the directory is lookup and insert. This would be easy in languages with built-in support for useful data structures, but I'm a foreigner to C and looking around on Google did (surprisingly) not answer my question satisfactorily. This project looks about right: http://uthash.sourceforge.net/ but I would need to come up with my own hash key generator. This is a standard, simple problem, so I hope there is a standard and simple solution.

  • select columns by a concat text as columnname in oracle

    - by glaudiston
    I have a table with columns named with the number of hour of day like this: col00 NUMBER(5) col01 NUMBER(5) col02 NUMBER(5) ... col23 NUMBER(5) ...and I have another query that returns a count by hour. I want to recover the colXX value by hour.... then I can recover with "decode" or "case when..." but I want know if exists any way to recover the column by a text like this: select "col"||hour from table; in the hypothetical above example if hour is 13 then would be translated like: select col13 from table; there is any way to do this ?

  • Return from parent sub in Perl

    - by JS Bangs
    I want to write a subroutine which causes the caller to return under certain conditions. This is meant to be used as a shortcut for validating input to a function. What I have so far is: sub needs($$) { my ($condition, $message) = @_; if (not $condition) { print "$message\n"; # would like to return from the *parent* here } return $condition; } sub run_find { my $arg = shift @_; needs $arg, "arg required" or return; needs exists $lang{$arg}, "No such language: $arg" or return; # etc. } The advantage of returning from the caller in needs would then be to avoid having to write the repetitive or return inside run_find and similar functions.

  • Uniquely identifying mobile devices over a network for webforms

    - by Eric
    I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

  • Java Servlet says file does not exist

    - by Austin
    Hello World! I have developed a java servlet that monitors a folder on a network drive for new files then does some actions on them depending on what kind of file it is. It worked in Eclipse when Eclipse and Tomcat were running with each other, but now that I have deployed it onto a server(different machine), the servlet keeps logging that it cannot find the folder to be mapped. The exact same network drive is mapped, and the folder definitely exists. This problem only occurs when the servlet is run on the server, not on the development machine. Thanks! PS: It is a Windows Server 2003 Enterprise Server with Tomcat v6 installed.

  • Check for duplicate rows in 2 columns before update

    - by user3891378
    I have a table with 4 columns, and I need to check to see if a Column Pair exists before inserting a row into the database: INSERT INTO dbo.tblCallReport_Detail (fkCallReport, fkProductCategory, Discussion, Action) VALUES (?, ?, ?, ?) The pair in question is fkCallReport and fkProductCategory. For example if the row trying to be inserted has fkCallReport = 3 and fkProductCategory = 5, and the database already has both of those values together, it should display an error and ask if they would like to combine the Disuccsion and Action with the current record. Keep in mind I'm doing this in VBA Access 2010 and am still very new.

  • Lucene search on specific field name?

    - by Rachel
    I have been playing around with an installation of SOLR that indexes some data from my database. I am able to index data and query it back but I was wondering about how field name queries work. For certain fields I am able to specify their name and the search text to have the results return as expected and for other fields, when I specify their name and search text, no results are returned. q=type:book //(this will work) q=type:book AND title:"The Title" //(no results returned) In this example, type is a required field and title is not. For the example where I search by title, I can see the document in the results of the first query having the given title so I know that a document exists that matches this search. Is making a field 'required' the only way to be able to search by field name? [edit] I'm using the default installation and the 'example' folder inside of solr, editing the xml files and using the interface available through start.jar to be able to run, index and query.

  • How to test if an array contains a pair of numbers whose product is odd?

    - by John
    How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. Yes, this is a function out of a textbook. No, this is not homework—I'm just trying to learn, so please no "do your own homework comments."
