• Overriding PEAR error handler

  - by Rolf

  Hi everyone, I'm currently working on an application that requires lots of external libraries. My job right now is set a unique error handler that will manage every error. So far, I found 7 different types of PEAR errors: PEAR_ERROR_RETURN: PEAR_ERROR_EXCEPTION: PEAR_ERROR_CALLBACK: PEAR_ERROR_EXCEPTION: PEAR_ERROR_PRINT: PEAR_ERROR_TRIGGER: PEAR_ERROR_DIE: I want to handle only the serious error (like the native E*_ERROR). The only problem is I have absolutely no idea about PEAR error criticity ! Those names are more related to the way of handling them than to their seriousness... Is there a real documentation about it ? I guess a better solution would consist in using their pushErrorHandling, but I just don't understand how to use it... If someone here knows, I'd be grateful... Thanks in advance !

• Test whether a glob has any matches in bash

  - by Ken Bloom

  If I want to check for the existance of a single file, I can test for it using test -e filename or [ -e filename ]. Supposing I have a glob and I want to know whether any files exist whose names match the glob. The glob can match 0 files (in which case I need to do nothing), or it can match 1 or more files (in which case I need to do something). How can I test whether a glob has any matches.? (test -f glob* fails if the glob matches more than one file.)

• database vs flat file, which is a faster structure for "regex" matching with many simultaneous reque

  - by Jamex

  Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? Addition info: If I want to find all the cities have the pattern "cis" in their names. Which is better/faster, using regex or string functions? Please recommend a strategy TIA

• How can I limit the number of connections to an mssql server from my tomcat deployed java applicatio

  - by CJ

  Hi, I have an application that is deployed on tomcat on server A and sends queries to a huge variety of mssql databases on an server B. I am concerned that my application could overload this mssql database server and would like some way to preventing it making requests to connect to any database on that server if some arbitrary number of connections were already in existence and unclosed. I am looking at using connection pooling but am under the impression that this will only pool connections to a specific database on the mssql server, I want to control the total of these combined connections that will occur to many different databases (incidentally I can only find out the names of individual db's dynamically as they change day to day). Will connection pooling take care of this for me, are am I looking at this from the wrong perspective? I have no access to the configuration of the mssql server. Links to tutorials or working examples of your suggested solution are most welcome! Thanks, Caroline

• What's the proper technical term for "high ascii" characters?

  - by moodforaday

  What is the technically correct way of referring to "high ascii" or "extended ascii" characters? I don't just mean the range of 128-255, but any character beyond the 0-127 scope. Often they're called diacritics, accented letters, sometimes casually referred to as "national" or non-English characters, but these names are either imprecise or they cover only a subset of the possible characters. What correct, precise term that will programmers immediately recognize? And what would be the best English term to use when speaking to a non-technical audience?

• How do I draw an ESB on a SoaML diagram?

  - by dave

  I've recently had to draw some architectural diagrams that feature the use of an Enterprise Service Bus. The ESB is critical, so everyone wants it to show up on the diagram. But since it's the center of what everything is connected to, it really of gets in the way. I settled on trying to use SoaML. I color-coded the request points blue and service points green, to help then stand out. The text names on the ports give you a sense of what talks to what, and it's incredibly obvious that everything goes through the ESB. Can anyone comment on my approach? Any suggestions on something better?

• How to use a CTabCtrl in a MFC dialog based application ?

  - by shan23

  I need to do something which i expected to be was simple - create a tab control which has 2 tabs, implying 2 modes of operation for my app. When user clicks on Tab1, he'll be presented with some buttons and textboxes, and when he clicks Tab2, some other input method. I noticed that there was a CTabCtrl class thats used in MFC to add tabs. However, once I added the tab ctrl using the UI designer, I couldn't specify how many tabs there'll be using property window. Searching on the net, I found some examples but all of them required you to derive from CtabCtrl , create 2 or more child dialogs etc and to write your own custom class. My question is, since I want to do something so basic, why couldn't I do it using the familiar Add Event handler/Add member variable wizard and then handle everything else inside my app's class ? Surely, the default CTabCtrl class can do something useful without needing to derive from it ?

• DOS batch script to list folders that have a specific file in them

  - by Lee

  I'm trying to create a file that has a list of directories that have a specific file name in them. Let's say I'm trying to find directories that have a file named *.joe in them. I initially tried just a simple dir /ad *.joe dir_list.txt , but it searches the directory names for *.joe, so no go. Then I concluded that a for loop was probably my best bet. I started with for /d /r %a in ('dir *.joe /b') do @echo %a dir_list.txt and it looked like it wasn't executing the dir command. I added the "usebackq", but that seems to only work for the /F command extension. Ideas?

• dvi generation: no bounding box

  - by Akshey

  Hi, I wrote a research paper in latex and generated pdf using kile. It worked perfectly well. Now conference people are asking for dvi file also. But Kile's quick build process does not give a dvi file, but its 'Latex' compile process does. So I tried to compile the document, and it gave errors for includegraphics saying figure not found. When I append the correct extensions to the image names, that errors stopped coming but new errors came "bounding box is missing". I added bounding box values and now DVI file is being generated. My questions are: I have tried giving very high and low bounding box values but there is no deformation in the PDF. Why? Can I generate a DVI without giving bounding box values? Thanks and regards, Akshey

• SQL Server Import table keeping default values

  - by Chrissi

  I am importing a table from one database to another in SQL Server 2008 by right-clicking the target database and choosing Tasks Import Data... When I import the table I get the column names and types and all the data fine, but I lose the primary key, identity specifications and all the default values that were set in the source table. So now I have to set all the default values for each column again manually. Is there any way to get the default values with the import, or even after with a Query? I am VERY new to this and flailing in the dark, so forgive me if this is a really stupid question...

• Limit on FileReference uploads?!

  - by Rudy

  Hello, I am currently uploading files in ActionScript 3 using the upload() method of the FileReference class. I built an uploader than can do simultaneous or parallel uploads, having a variable set the number of maximum uploads at a time. I noticed that for Internet Explorer I could be uploading 10 or more files simultaneously, but FireFox and Safari seems to cap the number of uploads to 2. That is, when I call the upload method on per say, 3 files, only 2 will get events back (such as ProgressEvent.PROGRESS). Only when one of the 2 uploads finishes, then the 3rd one will start. This behavior does not happen for Internet Explorer. I have tried with a large number of files, and some big files, to make sure this behavior was consistent. I was wondering if anyone noticed this behavior please, and if so, what is the reason for this behavior please? I appreciate your help, Thank you very much, Rudy

• Java: How do you access a sub-object of an object with no "getXXX" method to that sub-object

  - by Daxon

  I'll explain with pictures from Eclipse Debugger I have an Class called "FieldContext", (I can't edit it, it's compiled in the Java OVal API) Within "FieldContext" on the eclipse variable tab are "CompileTimeType" and "field" Q1 Is there a legend for the icons in the variables tab? like what the red box with the "F" means + yellow diamond boxes? Now I want to access the fields inside the "field" object (RedBox) .. preferably "name" But the "FieldContext" does not have a "getField()" method, yet it has a "getCompileTimeType()" method. Q2 So is there anyway to get that field object being a "SerializableField" Class from the "FieldContext"? If eclipse debugger can see/get/edit them then I hope I can do the same in Java.

• Getting javascript mouse position relative to website prefferably without jQuery

  - by Constructor

  I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

• Assigning a MVC Controller property from Asp.Net page

  - by JasonMHirst

  I don't know if I've understanding MVC correctly if my question makes no sense, but I'm trying to understand the following: I have some code on a controller that returns JSON data. The JSON data is populated based on a choice from a dropdown box on an Asp.Net page. I thought (incorrectly) that Session variables would be shared between the Asp.Net project and the MVC Project. What I'd like to do therefore (if this is possible), is to call a Sub on the MVC that sets a variable before the JSON query is run. I have the following: Sub SetCountryID(ByVal CountryID As Integer) Me.pCountrySelectedID = CountryID End Sub Which I can call by the following: Response.Write("http://localhost:7970/Home/SetCountryID/?CountryID=44") But this then results in a blank page - again obviouslly totally incorrect! Am I going about MVC the wrong way or do I still have a hell of a lot more learning to do? Is this even possible to do?

• Loading textures in an Android OpenGL ES App.

  - by Omega

  I was wondering if anyone could advise on a good pattern for loading textures in an Android Java & OpenGL ES app. My first concern is determining how many texture names to allocate and how I can efficiently go about doing this prior to rendering my vertices. My second concern is in loading the textures, I have to infer the texture to be loaded based on my game data. This means I'll be playing around with strings, which I understand is something I really shouldn't be doing in my GL thread. Overall I understand what's happening when loading textures, I just want to get the best lifecycle out of it. Are there any other things I should be considering?

• Javascript: window.onload problem

  This isn't working in IE (although it does work in FFX). Why? Using HTML in the header: <script type="application/javascript"> // And finally, let's call the code ourselves. window.onload = lbp.init; </script> And then the script: // lbp is the script's universal variable, which retains everything var lbp = {}; // The sequence of functions to trigger lbp.init = function() { alert('hi'); } Thanks in advance for your help =)

• Update JProgressBar from new Thread

  - by Dacto

  How can I update the JProgressBar.setValue(int) from another thread? My secondary goal is do it in the least amount of classes possible. Here is the code I have right now: **Part of the main class....** pp.addActionListener( new ActionListener(){ public void actionPerformed(ActionEvent event) { new Thread(new Task(sd.getValue())).start(); } }); public class Task implements Runnable{ int val; public Task(int value){ this.val = value; } @Override public void run() { for (int i=0; i<=value; i++){ //Progressively increment variable i pbar.setValue(i); //Set value pbar.repaint(); //Refresh graphics try{Thread.sleep(50);} //Sleep 50 milliseconds catch (InterruptedException err){} } } } pp is a JButton and starts the new thread when the JButton is clicked. pbar is the JProgressBar object from the Main class. How can I update its value?(progress) The code above in run() cannot see the pbar.

• Difficulties of transforming a Java program to another language (or vice versa)

  - by NomeN

  Is there anything simple Java can't do that can be done in a similar language or vice versa? Lets say you have a piece of software in language X and you rewrite it entirely to Java (or the other way around), what are the little things that would seriously hamper the translation? At first I was thinking of comprehensions or multiple exit loops, but these are easily rewritten with a for_each loop with an if statement and a local variable respectively. Maybe Exceptions? But which language does not have a similar construct? Polymorphism? But I don't see how I could show that in a few lines. I'm looking for a short and sweet example, that would give some serious headache to work around.

  Hello commnunity, i have somthing like this: (if this page needs the user to be logged) if(!isset($_SESSION['usr_id'])){ //if not a logged user $_SESSION['redir']=curPageURL();//Saving the current page for the redirection header('Location: ../Session/loginFrm.php'); } and in loginFrm.php, we do: {...after validation} if(isset($_SESSION['redir'])){ header('Location: '.$_SESSION['redir']); }else{...} in this page, they say we should use something like this instead: ... require_once '../Session/loginFrm.php'; exit(); This doesn't work for me, the session variable now contains the included page, and not the current page. What do you think about?

• Data bind enum properties to grid and display description

  - by TrueWill

  This is a similar question to How to bind a custom Enum description to a DataGrid, but in my case I have multiple properties. public enum ExpectationResult { [Description("-")] NoExpectation, [Description("Passed")] Pass, [Description("FAILED")] Fail } public class TestResult { public string TestDescription { get; set; } public ExpectationResult RequiredExpectationResult { get; set; } public ExpectationResult NonRequiredExpectationResult { get; set; } } I'm binding a BindingList<TestResult> to a WinForms DataGridView (actually a DevExpress.XtraGrid.GridControl, but a generic solution would be more widely applicable). I want the descriptions to appear rather than the enum names. How can I accomplish this? (There are no constraints on the class/enum/attributes; I can change them at will.)
