  • How to begin writing an Application Server over Apache?

    - by Cracker
    For my college project, I want to create a simple application server in C that runs over Apache. Like .php, .asp, .jsp, the extension of my files would be .sas. I have already written a parser which reads the .sas files and generates the output. For example, consider a file index.sas with the below code: <% echo "Hello"; %> Now, if I execute: sas index.sas The result would be: Hello Now I want to use this program as an application server over Apache just as PHP, Tomcat, etc. work over Apache. I have heard of cgi-bin but I think PHP uses a different approach. I want to learn the approach which PHP uses. Please advice.

  • Good code architecture for this problem?

    - by RCIX
    I am developing a space shooter game with customizable ships. You can increase the strength of any number of properties of the ship via a pair of radar charts*. Internally, i represent each ship as a subclassed SpaceObject class, which holds a ShipInfo that describes various properties of that ship. I want to develop a relatively simple API that lets me feed in a block of relative strengths (from minimum to maximum of what the radar chart allows) for all of the ship properties (some of which are simplifications of the underlying actual set of properties) and get back a ShipInfo class i can give to a PlayerShip class (that is the object that is instantiated to be a player ship). I can develop the code to do the transformations between simplified and actual properties myself, but i would like some recommendations as to what sort of architecture to provide to minimize the pain of interacting with this translator code (i.e. no methods with 5+ arguments or somesuch other nonsense). Does anyone have any ideas? *=not actually implemented yet, but that's the plan.

  • How do I retain a requested url with parameters after redirecting to a login page?

    - by Brent Parker
    I have been asked to set up some authentication for some content on our website using JSP. What I would like to do seems simple to me but I can't quite figure out how to do it in JSP. What I would like to do is this: When a user requests a page that you must be logged in to see, I have a tag that checks their cookies for an authentication token. If it is not there, they are redirected to a login page. After they log in, I want to redirect them back to the page they first requested along with any parameters they were sending. Now, I have the tag that is checking their authentication and redirecting them to the login page. That part is working just fine. But I'm not sure how to maintain the first requested url and parameters so they can be redirected after they login. How might I accomplish this?

  • C# Dynamic Query Without A Database Model

    - by hitopp
    I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

  • How to prevent UI from freezing during lengthy process?

    - by OverTheRainbow
    Hello, I need to write a VB.Net 2008 applet to go through all the fixed-drives looking for some files. If I put the code in ButtonClick(), the UI freezes until the code is done: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'TODO Find way to avoid freezing UI while scanning fixed drives Dim drive As DriveInfo Dim filelist As Collections.ObjectModel.ReadOnlyCollection(Of String) Dim filepath As String For Each drive In DriveInfo.GetDrives() If drive.DriveType = DriveType.Fixed Then filelist = My.Computer.FileSystem.GetFiles(drive.ToString, FileIO.SearchOption.SearchAllSubDirectories, "MyFiles.*") For Each filepath In filelist 'Do stuff Next filepath End If Next drive End Sub Google returned information on a BackGroundWorker control: Is this the right/way to solve this issue? If not, what solution would you recommend, possibly with a really simple example? FWIW, I read that Application.DoEvents() is a left-over from VBClassic and should be avoided. Thank you.

  • How to be notified when a script's background job completes?

    - by Keith Bentrup
    My question is very similar to this one except that my background process was started from a script. I could be doing something wrong but when I try this simple example: #!/bin/bash set -mb # enable job control and notification sleep 5 & I never receive notification when the sleep background command finishes. However, if I execute the same directly in the terminal, $ set -mb $ sleep 5 & [1]+ Done sleep 5 I see the output that I expect. I'm using bash on cygwin. I'm guessing that it might have something to do with where the output is directed, but trying various output redirection, I'm not getting any closer?

  • How to prevent filename expansion in for loop in bash

    - by cagri
    In a for loop like this, for i in `cat *.input`; do echo "$i" done if one of the input file contains entries like *a, it will, and give the filenames ending in 'a'. Is there a simple way of preventing this filename expansion? Because of use of multiple files, globbing (set -o noglob) is not a good option. I should also be able to filter the output of cat to escape special characters, but for i in `cat *.input | sed 's/*/\\*'` ... still causes *a to expand, while for i in `cat *.input | sed 's/*/\\\\*'` ... gives me \*a (including backslash). [ I guess this is a different question though ]

  • Linq to SQL Strange SQL Translation

    - by Master Morality
    I have a simple query that is generating some odd SQL translations, which is blowing up my code when the object is saturated. from x in DataContext.MyEntities select new { IsTypeCDA = x.EntityType == "CDA" //x.EntityType is a string and EntityType.CDA is a const string... } I would expect this query should translate to: SELECT (CASE WHEN [t0].[EntityType] = @p1 THEN 1 ELSE 0 END) as [IsTypeCDA] ... Instead I get this : SELECT (CASE WHEN @p1 = [t0].[EntityType] THEN 1 WHEN NOT (@p1 = [t0].[EntityType]) THEN 0 ELSE NULL END) AS [IsTypeCDA] ... Since I'm saturating a POCO where IsTypeCDA is a bool, it blows up stating I can't assign null to bool. Any thoughts? Edit: fixed the property names so they make sense...

  • jquery draggable into sortable only works after sorting

    - by Dao
    Hi, I'm experiencing problems with a simple combination of a Draggable and Sortable: initially, the dragging does not work and I do not get a receive callback. Only after I have done a sort (i.e. change the position of things in #workarea), can I drag new things into it. Somehow it seems as if the sortable needs to be 'initialized' before it accepts draggables. My code, in a simplified version: $(".element_draggable").draggable({ zIndex: 2, helper: 'clone', connectToSortable: '#workarea'}); $("#workarea").sortable({ receive: function() {alert('received');} }); Does anyone have an idea on what I could be doing wrong here?

  • Check if row already exists, if so tell the referenced table the id

    - by flhe
    Let's assume I have a table magazine: CREATE TABLE magazine ( magazine_id integer NOT NULL DEFAULT nextval(('public.magazine_magazine_id_seq'::text)::regclass), longname character varying(1000), shortname character varying(200), issn character varying(9), CONSTRAINT pk_magazine PRIMARY KEY (magazine_id) ); And another table issue: CREATE TABLE issue ( issue_id integer NOT NULL DEFAULT nextval(('public.issue_issue_id_seq'::text)::regclass), number integer, year integer, volume integer, fk_magazine_id integer, CONSTRAINT pk_issue PRIMARY KEY (issue_id), CONSTRAINT fk_magazine_id FOREIGN KEY (fk_magazine_id) REFERENCES magazine (magazine_id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION ); Current INSERTS: INSERT INTO magazine (longname,shotname,issn) VALUES ('a long name','ee','1111-2222'); INSERT INTO issue (fk_magazine_id,number,year,volume) VALUES (currval('magazine_magazine_id_seq'),'8','1982','6'); Now a row should only be inserted into 'magazine', if it does not already exist. However if it exists, the table 'issue' needs to get the 'magazine_id' of the row that already exists in order to establish the reference. How can i do this? Thx in advance!

    I am using the CodeSorcery arm-eabi-gcc tool chain and I have a problem using ld separate from gcc I can compile my simple program and link it, if I let gcc call the ld. This works not problem g++ test.cpp; # Works This does not work because of missing symbols g++ -c test.cpp ld -o test crti.o crtbegin.o test.o crtend.o crtn.o -lgcc -lc -lstdc++; # Fails Notice I am adding the gcc libraries to the ld command What am I missing? Also if there is a better way to make configuring ld to using the default gcc linking? Thanks

  • Building and rendering a bitmap from a double array

    - by Ami
    I'm new to c# and I'm sure I'm missing something simple here. I'm trying to build a bitmap from integer values (0-255) in a double array and then render it in a PictureBox. I think my Bitmap is getting generated but it isn't displaying in my PictureBox. Bitmap bmp = new Bitmap(image_width, image_height); Color pxl_color = new Color(); for (int i = 0; i < image_width; i++) { for (int j = 0; j < image_height; j++) { pxl_color = Color.FromArgb(array_bitmap[i][j]); bmp.SetPixel(i, j, pxl_color); } } PictureBox1.Image = bmp; Thanks in advance.

  • SQL Server uncorrelated subquery very slow

    - by brianberns
    I have a simple, uncorrelated subquery that performs very poorly on SQL Server. I'm not very experienced at reading execution plans, but it looks like the inner query is being executed once for every row in the outer query, even though the results are the same each time. What can I do to tell SQL Server to execute the inner query only once? The query looks like this: select * from Record record0_ where record0_.RecordTypeFK='c2a0ffa5-d23b-11db-9ea3-000e7f30d6a2' and ( record0_.EntityFK in ( select record1_.EntityFK from Record record1_ join RecordTextValue textvalues2_ on record1_.PK=textvalues2_.RecordFK and textvalues2_.FieldFK = '0d323c22-0ec2-11e0-a148-0018f3dde540' and (textvalues2_.Value like 'O%' escape '~') ) )

  • how to add column in SQL Query that incl. LEFT OUTER JOIN

    - by radbyx
    I have this Query: SELECT p.ProductName, dt.MaxTimeStamp, p.Responsible FROM Product p LEFT JOIN (SELECT ProductID, MAX(TimeStamp) AS MaxTimeStamp FROM StateLog WHERE State = 0 GROUP BY ProductID, Status) dt ON p.ProductID = dt.ProductID ORDER BY p.ProductName; It works like it should, but now I need to SELECT "State" out too. The tricky part is, that I only want the lastest "TimeStamp" where "State" was false. But now I also need the "State" for the lastest "TimeStamp". I tried this: SELECT p.ProductName, dt.State, dt.MaxTimeStamp, p.Responsible FROM Product p LEFT JOIN (SELECT ProductID, MAX(TimeStamp) AS MaxTimeStamp, State FROM StateLog WHERE State = 0 GROUP BY ProductID, Status) dt ON p.ProductID =dt.ProductID ORDER BY p.ProductName; But it didn't work, because it gave me the "State" for the lastest "TimeStamp". So I hope there is some clever heads out there that can help me. I'm guessing that this is either very simple or very hard to solve.

  • How few a files does it take to load a program on Linux?

    - by BCS
    The (hypothetical for now) situation is the user of my system is going to be given a chunk of C code and needs my system to compile and run it in a chroot sandbox that is generated on the fly and I want to require the fewest files in the box as possible. I'm only willing to play with compiler and linker settings (e.g. static link everything I can expect to be able to find) and make some moderate restriction on what the code can expect use (e.g. they can't use arbitrary libs). The question is how simple can I get the sandbox. Clearly I need the executable, but what about an ELF loader and a .so for the system calls? Can I dump either of them and is there something else I'll need?

  • smallest perimiter rectangle with given integer area and integer sides

    - by remuladgryta
    Given an integer area A, how can one find integer sides w and h of a rectangle such that w*h = A and w+h is as small as possible? I'd rather the algorithm be simple than efficient (although within reasonable efficiency). What would be the best way to accomplish this? Finding out the prime factors of A, then combining them in some way that tries to balance w and h? Finding the two squares with integer sides with areas closest to A and then somehow interpolating between them? Any other method i'm not thinking of?

  • How to save event handlers, when we set new html for element?

    - by Kai
    I have simple html markup: <div id="cont">Some text here <div class="wrap" style="border: 1px solid black;display: inline;"> block element here </div> and another text</div> And jQuery code: $(function(){ $(".wrap").click(function(){ $("#cont").html($("#cont").html().replace(/text/g, "letter")); alert("Click!"); }); $("#d1").click(function(){ alert("#d1 clicked!"); }); }); I expect that click event will be fire any time you clicked by the #d1 div, but when we clicked by .wrap it neve fire again. I understand why it has such behavior, but how to solve it? In my code I can't set click event for #d1 after $("#cont").html($("#cont").html().replace(/text/g, "letter")) because I don't now at execution time if event was set. You can try example on JSBin

  • Applying a function with multiple inputs using Map? (Haskell)

    - by Schroedinger
    G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

  • JQuery with SMARTY php

    This might seem a very noob question but I haven't found the answer yet. I have a header.tpl file which contains xhtml code. I want to and some java script to it using jquery. But my problem is that it simple doesn't happen what I tell it to do. Because the page hoster comiples php with SMARTY I had to make a small change to the block script, which was had the {literal} {/literal}. But the rest seems ok. Btw the jquery.js is on the same folder as the header.tpl. File header.tpl http://feupload.fe.up.pt/get/SQWJvybQkDCmjEG PS: I event replaced all the code by the getstarted tutorial on the jquery homepage and added the {literlar} {/literal} (otherwise it would give an error) and it steel didn't work

  • How does py2exe actually -and simply explained- work? :)

    - by sandra
    Hi folks, I have a c++ app that calls another python one (bundled into an exe with py2exe) So I have 2 apps. So I was wondering: What if my c++ did what py2exe does? i.e. embed the python app in the c++ one. This way I won't depend on py2exe and its configurations nighmares (yes, it has some) Hence my questions: how does py2exe work (so I can do its job with my c++ app) What about just embedding the whole python app with the c++? I read the python doc about embedding, did an example (a very simple one that does PyRun_SimpleString) but what about a whole python app with tons of modules? (zipimport maybe?) I'd love to hear how you'd do that. Thanks a lot! :)

  • links in codeigniter

    - by Patrick
    hi All, I'm experimenting with codeigniter but don't really understand how links work. for example, I have a link like this: localhost/ci/welcome/cat/7 My base url is localhost/ci, so by clicking on this link I would expect the method "cat" of controller "welcome" to be called. This method is very simple: function cat() { echo "just a test."; } Pretty basic - I would expect to see the text on screen, but I just see a 404 -page not found error. What could be the problem?

  • How to call a specific, unknown Python object attribute?

    - by Michael Morisy
    I'm working to create a simple Python script that will ultimately tell you how many blog entries were posted in a given month, and the pyblog app is proving very helpful. However, when I create the blog object, I don't know how to access it's various attributes. I can print them all out by printing one item from the dictionary, as shown (in excerpts) below: print blog.get_recent_posts(1) 'post_status': 'publish', 'date_created_gmt': <DateTime '20100601T19:27:17' at 2853300>, 'mt_excerpt': '', 'userid': '288', 'dateCreated': <DateTime '20100601T14:27:17' at 2853350>, 'custom_fields': [{'value': '', 'id': '1317', 'key': 'brightcove_code'}, {'value': 'http://bit.ly/d0Rywl', 'id': '1403', But how can I just get it to provide that DateTime information?

  • INSERT INTO statement that copies rows and auto-increments non-identity key ID column

    - by AmoebaMan17
    Given a table that has three columns ID (Primary Key, not-autoincrementing) GroupID SomeValue I am trying to write a single SQL INSERT INTO statement that will make a copy of every row that has one GroupID into a new GroupID. Example beginning table: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b Goal after I run a simple INSERT INTO statement: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b 3 | 2 | a 4 | 2 | b I thought I could do something like: INSERT INTO MyTable ( [ID] ,[GroupID] ,[SomeValue] ) ( SELECT (SELECT MAX(ID) + 1 FROM MyTable) ,@NewGroupID ,[SomeValue] FROM MyTable WHERE ID = @OriginalGroupID ) This causes a PrimaryKey violation since it will end up reusing the same Max(ID)+1 value multiple times as it seems. Is my only recourse to a bunch of INSERT statements in a T-SQL WHILE statement that has an incrementing Counter value? I also don't have the option of turning the ID into an auto-incrementing Identity column since that would breaking code I don't have source for.
