  • .NET equivalent to Perl regular expressions

    - by r_honey
    I need to convert a Perl script to VB.NET. I have managed almost the entire conversion, but some Perl (seemingly simple) regex are causing an headache. Can someone suggest me .NET equivalent of the following perl regex: 1) $letter =~ s/Users //,; $letter =~ s/Mailboxes //,; if($letter =~ m/$first_char/i){ 2) unless($storegroup =~ /Recovery/ || $storegroup =~ /Users U V W X Y Z/ || $storegroup =~ /Users S T/ || $storegroup =~ /Users Q R/){ The regex look simple to me. I tried to wade through perl.org but understanding a langugae regex takes sometime and I need to complete the conversion quickly.

  • JLabel not greyed out when disabled, when HTML text displayed

    - by bguiz
    How do I get a JLabel displaying a HTML string to appear greyed out (which is the behaviour of JLabels that don't display HTML text)? Is there another way than actually changing the colour myself by modifying the foreground property? JLabel label1 = new JLabel("Normal text"); JLabel label2 = new JLabel("<html>HTML <b>text</b>"); // Both labels are now black in colour label1.setEnabled(false); label2.setEnabled(false); // label1 is greyed out, label2 is still black in colour Thank you very much for all of your responses. From what I gather, it seems that Java doesn't support automatic greying out of JLabels when they use HTML text. Suraj's solution has come closest to the fix considering the limitations. I have however, tried a different out-of-the box approach, where I have put the HTML text JLabels inside of an inner JPanel and did this: mInnerPanel.setEnabled(shouldShow); //shouldShow is a boolean value Which hasn't worked. Any suggestions for this way? EDIT: Added implemented solution.

  • Sending solicited mass email

    - by Christian W
    Our company does work environment surveys, and these surveys are filled in online. All participants are sent a link to their survey in an email (personal code included). Some of our clients have employee counts in the hundreds and sometimes in the thousands. Our current solution is just using our SMTP-server to send this, without any form of throttling (VB6, CDO). (All recipients are usually "inside" the same domain, [email protected]) This is not a good solution, as you may imagine, this triggers every anti-spam/firewall/gatekeeper event in the clients environment. We are put in contact with their IT-department beforehand and get them to whitelist our sending server and sender-mail address. The most usual problems we run in to are: Receiving server only grabs the 20-50 first mails and rejects the rest (anti-spam measure). We sometimes can get by this by getting the it-company to whitelist us. Sometimes however, this does not work. It's getting more and more normal to disable bouncing of incorrect mail addresses. This gives us no indication of whether a mail has been delivered or not. And believe it or not, most clients gives us their email list from their HR-system, not their mailsystem. Does anyone have any suggestions for a better way to do this? We can't be the only company sending legitimate mass emails? :)

  • Ruby page loading very very slowly - how should I speed it up?

    - by Elliot
    Hey guys, I'm going to try and describe the code in my view, without actually posting all the garbage: It has a standard shell (header, footer etc. in the layout) this is also where the sub navigation exists which is based on a loop (to find the amount of options) - on this page, we have 6 subnav links. Then in the index view, we have a 3rd level nav - with 3 links that use javascript to link/hide divs on the page. This means each of those original 6 options, all have their own 3'rd level nav, with each of their own 3 div pages. These three pages/divs have the input form for creating a record in rails, and then the other 2 pages show the records in different assortments. ALL of this code lives on one page (aside from the shell). The original sub nav uses a javascript tab solution, to browse through all of it... (this means its about 6 divs, which all contain 4 divs of function - so about 24 heavy divs). Loading it seems to take forever, although after loaded its extremely fast (obviously). My big question, is how should I attack this? I don't know ajax - although I imagine it'd be a good solution for loading the tabs when clicked. Thanks! Elliot

  • MATLAB for kids?

    - by yuk
    My seven-years old expresses large interest in computers (well, who doesn't? :). Since I'm mostly program in MATLAB, I'm thinking why not to teach him MATLAB. We did a small project with him (he had to solve as many simple arithmetic problems as possible in a limited time) and he get pretty excited. I coded, he watched and then tested. He also likes to do create interesting graphics and simple animations. So, what's next? I would appreciate any ideas for interesting projects, games, graphics? What math concepts he has to understand to program in MATLAB? Or may be you would say it's too early and we should start with something like Logo, Scratch or Alice?

  • Optimizing MySQL update query

    - by Jernej Jerin
    This is currently my MySQL UPDATE query, which is called from program written in Java: String query = "UPDATE maxday SET DatePressureREL = (SELECT Date FROM ws3600 WHERE PressureREL = (SELECT MAX" + "(PressureREL) FROM ws3600 WHERE Date >= '" + Date + "') AND Date >= '" + Date + "' ORDER BY Date DESC LIMIT 1), " + "PressureREL = (SELECT PressureREL FROM ws3600 WHERE PressureREL = (SELECT MAX(PressureREL) FROM ws3600 " + "WHERE Date >= '" + Date + "') AND Date >= '" + Date + "' ORDER BY Date DESC LIMIT 1), ..."; try { s.execute(query); } catch (SQLException e) { System.out.println("SQL error"); } catch(Exception e) { e.printStackTrace(); } Let me explain first, what does it do. I have two tables, first is ws3600, which holds columns (Date, PressureREL, TemperatureOUT, Dewpoint, ...). Then I have second table, called maxday, which holds columns like DatePressureREL, PressureREL, DateTemperatureOUT, TemperatureOUT,... Now as you can see from an example, I update each column, the question is, is there a faster way? I am asking this, because I am calling MAX twice, first to find the Date for that value and secondly to find the actual value. Now I know that I could write like that: SELECT Date, PressureREL FROM ws3600 WHERE PressureREL = (SELECT MAX(PressureREL) FROM ws3600 WHERE Date >= '" + Date + "') AND Date >= '" + Date + "' ORDER BY Date DESC LIMIT 1 That way I get the Date of the max and the max value at the same time and then update with those values the data in maxday table. But the problem of this solution is, that I have to execute many queries, which as I understand takes alot more time compared to executing one long mysql query because of overhead in sending each query to the server. If there is no better way, which solution beetwen this two should I choose. The first, which only takes one query but is very unoptimized or the second which is beter in terms of optimization, but needs alot more queries which probably means that the preformance gain is lost because of overhead in sending each query to the server?

  • What's a good way of building up a String given specific start and end locations?

    - by Michael Campbell
    (java 1.5) I have a need to build up a String, in pieces. I'm given a set of (sub)strings, each with a start and end point of where they belong in the final string. Was wondering if there were some canonical way of doing this. This isn't homework, and I can use any licensable OSS, such as jakarta commons-lang StringUtils etc. My company has a solution using a CharBuffer, and I'm content to leave it as is (and add some unit tests, of which there are none (?!)) but the code is fairly hideous and I would like something easier to read. As I said this isn't homework, and I don't need a complete solution, just some pointers to libraries or java classes that might give me some insight. The String.Format didn't seem QUITE right... I would have to honor inputs too long and too short, etc. Substrings would be overlaid in the order they appear (in case of overlap). As an example of input, I might have something like: String:start:end FO:0:3 (string shorter than field) BAR:4:5 (String larger than field) BLEH:5:9 (String overlays previous field) I'd want to end up with FO BBLEH 01234567890

  • Avoid the problem with BigDecimal when migrating to Java 1.4 to Java 1.5+

    - by romaintaz
    Hello, I've recently migrated a Java 1.4 application to a Java 6 environment. Unfortunately, I encountered a problem with the BigDecimal storage in a Oracle database. To summarize, when I try to store a "7.65E+7" BigDecimal value (76,500,000.00) in the database, Oracle stores in reality the value of 7,650,000.00. This defect is due to the rewritting of the BigDecimal class in Java 1.5 (see here). In my code, the BigDecimal was created from a double using this kind of code: BigDecimal myBD = new BigDecimal("" + someDoubleValue); someObject.setAmount(myBD); // Now let Hibernate persists my object in DB... In more than 99% of the cases, everything works fine. Except that in really few case, the bug mentioned above occurs. And that's quite annoying. If I change the previous code to avoid the use of the String constructor of BigDecimal, then I do not encounter the bug in my uses cases: BigDecimal myBD = new BigDecimal(someDoubleValue); someObject.setAmount(myBD); // Now let Hibernate persists my object in DB... However, how can I be sure that this solution is the correct way to handle the use of BigDecimal? So my question is to know how I have to manage my BigDecimal values to avoid this issue: Do not use the new BigDecimal(String) constructor and use directly the new BigDecimal(double)? Force Oracle to use toPlainString() instead of toString() method when dealing with BigDecimal (and in this case how to do that)? Any other solution? Environment information: Java 1.6.0_14 Hibernate 2.1.8 (yes, it is a quite old version) Oracle JDBC 9.0.2.0 and also tested with 10.2.0.3.0 Oracle database 10.2.0.3.0

  • Android process killer

    - by Martin
    I have similar question, maybe you can help. Is it possible to get list of all process which are running in the Android system, and kill some of them? I know that there are some applications (task managers), but I would like to write my own, simple application. I would like to write simple task manager, just list of all process and button which will kill some of them. Could you just write some Java methods which I can call in order to get list of process, and method for killing them. Or just give me some advices. Thanks for answers. Regards Martin

  • Accessing Unicode telugu text from Ms-Access Database in Java

    - by Ravi Chandra
    I have an MS-Access database ( A English-telugu Dictionary database) which contains a table storing English words and telugu meanings. I am writing a dictionary program in Java which queries the database for a keyword entered by the user and display the telugu meaning. My Program is working fine till I get the data from the database, but when I displayed it on some component like JTextArea/JEditorPane/ etc... the telugu text is being displayed as '????'. Why is it happening?. I have seen the solution for "1467412/reading-unicode-data-from-an-access-database-using-jdbc" which provides some workaround for Hebrew language. But it is not working for telugu. i.e I included setCharset("UTF8")before querying from the database. but still I am getting all '?'s. As soon as I got data from Resultset I am checking the individual characters, all the telugu characters are being encoded by 63 only. This is my observation. I guess this must be some type of encoding problem. I would be very glad if somebody provides some solution for this. Thanks in advance.

  • Problem on "Finding cursor position" function

    - by sanceray3
    Hi all, Few days ago, I have found a solution to obtain the cursor position on a div with contentedit="true". I use the solution defined on this web site : Finding cursor position in a contenteditable div function getCursorPos() { var cursorPos; if (window.getSelection) { var selObj = window.getSelection(); var selRange = selObj.getRangeAt(0); cursorPos = findNode(selObj.anchorNode.parentNode.childNodes, selObj.anchorNode) + selObj.anchorOffset; /* FIXME the following works wrong in Opera when the document is longer than 32767 chars */ } else if (document.selection) { var range = document.selection.createRange(); var bookmark = range.getBookmark(); /* FIXME the following works wrong when the document is longer than 65535 chars */ cursorPos = bookmark.charCodeAt(2) - 11; /* Undocumented function [3] */ } return cursorPos; } function findNode(list, node) { for (var i = 0; i < list.length; i++) { if (list[i] == node) { return i; } } return -1; } It functions well, but when I use html tags inside the div the pointer doesnt show the correct position. For example if I try to find cursor position on the <strong>cat</strong> is black, the function doesn't return me the good position. But if I try on the cat is black, it functions. Any ideas how to get the position with html tags ? Thanks for your help.

  • MySQL & PHP - Creating Multiple Parent Child Relations

    - by Ashok
    Hi, I'm trying to build a navigation system using categories table with hierarchies. Normally, the table would be defined as follows: id (int) - Primary key name (varchar) - Name of the Category parentid (int) - Parent ID of this Category referenced to same table (Self Join) But the catch is that I require that a category can be child to multiple parent categories.. Just like a Has and Belongs to Many (HABTM) relation. I know that if there are two tables, categories & items, we use a join table categories_items to list the HABTM relations. But here i'm not having two tables but only table but should somehow show HABTM relations to itself. Is this be possible using a single table? If yes, How? If not possible, what rules (table naming, fields) should I follow while creating the additional join table? I'm trying to achieve this using CakePHP, If someone can provide CakePHP solution for this problem, that would be awesome. Even if that's not possible, any solution about creating join table is appreciated. Thanks for your time.

  • Linux: How to find all serial devices (ttyS, ttyUSB and others)?

    - by Thomas Tempelmann
    What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though?

  • How to map different UI views in a RESTful web application?

    - by MicE
    Hello, I'm designing a web application, which will support both standard UIs (accessed via browsers) and a RESTful API (an XML/JSON-based web service). User agents will be able to differentiate between these by using different values in the Accept HTTP header. The RESTful API will use the following URI structure (example for an "article" resource): GET /article/ - gets a list of articles POST /article/ - adds a new article PUT /article/{id} - updates an existing article based on {id} DELETE /article/{id} - deletes an existing article based on {id} The UI part of the application will however need to support multiple views, for example: a standard resource view a view for submitting a new resource a view for editing an existing resource a view for deleting an existing resource (i.e. display delete confirmation) Note that the latter three views are still accessed via GET, even though they are processed via overloaded POST. Possible solution: Introduce additional parameters (keywords) into URIs which would identify individual views - i.e. on top of the above, the application would support the following URIs (but only for Content-Type: text/html): GET /article/add - displays a form for adding a new article (fetched via GET, processed via POST) GET /article/123 - displays article 123 in "view" mode (fetched via GET) GET /article/123/edit - displays article 123 in "edit" mode (fetched via GET, processed via PUT overloaded as POST) GET /article/123/delete - displays "delete" confirmation for article 123 (fetched via GET, processed via DELETE overloaded as POST) A better implementation of the above might be to put the add/edit/delete keywords into a GET parameter - since they do not change the resource we're working with, it might be better to keep the base URI same for all of them. My question is: How would you map the above URI structure to UIs served to the regular user, considering that there can be several views per each resource, please? Do you agree with the possible solution detailed above, or would you recommend a different approach based on your experience? NB: we've already implemented an application which consists of a standalone RESTful API and a standalone web application. I'm currently looking into options for future projects where these two would be merged together (i.e. in order to reduce overhead). Thank you, M.

  • What would be the equivalent VB.NET code for this C# FluentNHibernate component mapping?

    - by Will Marcouiller
    I'm a C# programmer constrained to write VB.NET code. While exploring NHibernate further for my current client, I encountered FluentNHibernate, which I find real attractive. But now, I wonder how to "translate" this C# code for component mapping into VB.NET code: Component(x => x.Address, m => { m.Map(x => x.Number); m.Map(x => x.Street); m.Map(x => x.PostCode); }); I know from here: Component(Of Client)(Function(c) c.Address, ...) what I miss is how to continue with the brackets in VB.NET, since there's no Begin End keywords or so. EDIT 1: Following Mr. JaredPar instructions, I figured that his solution might work. If we take the time to read his answer, we may notice that we both don't know what the MType is within his solution. I might have found out that the MType is: FluentNHibernate.Mapping.ComponentPart(Of TComponent) Thus, TComponent is, from my understanding, an anonymous type that I shall parameter to use. From this point of view, since I wish to map the properties of my Address object, replacing TComponent in my help method signature seems not to work. Private Sub MapAdresseHelper(Of Adresse)(ByVal a As FluentNHibernate.Mapping.ComponentPart(Of Adresse)) a.Map(Function(m) m.Number) a.Map(Function(m) m.Street).Length(50) a.Map(Function(m) m.PostCode).Length(10) End Sub The error I get is that my Address class doesn't have a property member named Street, for instance. It sees my Address type, it recognizes it, but it seems buggy somehow. I guess VBNET is poorly designed for lambda expressions and is less evolved than C# (Sorry, a bit of frustration due to the constraint of working with it and not being capable of doing things VERY easily done in C#.) Thanks!

  • set label value in vb.net

    - by julio
    Hi-- I'm usually a PHP guy but got stuck doing a project in vb.net. I have a query (sqldatasource) that returns a single value (the last update date). I want to use a label to say something like "Last updated: " < Label = (returned value) In PHP this would be simple. In vb.net, all I can find are endless badly written code behinds showing how you'd execute the query onLoad then bind it to the label. Is this really the only way to do this? It seems like a ridiculously simple problem to have such a long solution. I have used a datagrid control to just bind the query result directly, but it prints the column name as well as the date, so it's not ideal. Any ideas?

  • Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

    - by Kaveh Shahbazian
    What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • Delphi - Populate an imagelist with icons at runtime 'destroys' transparency

    - by ben
    Hi again, I've spended hours for this (simple) one and don't find a solution :/ I'm using D7 and the TImageList. The ImageList is assigned to a toolbar. When I populate the ImageList at designtime, the icons (with partial transparency) are looking fine. But I need to populate it at runtime, and when I do this the icons are looking pretty shitty - complete loose of the partial transparency. I just tried to load the icons from a .res file - with the same result. I've tried third party image lists also without success. I have no clue what I could do :/ Thanks 2 all ;) edit: To be honest I dont know exactly whats going on. Alpha blending is the correkt term... Here are 2 screenies: Icon added at designtime: Icon added at runtime: Your comment that alpha blending is not supported just brought the solution: I've edited the image in an editor and removed the "alpha blended" pixels - and now it looks fine. But its still strange that the icons look other when added at runtime instead of designtime. If you (or somebody else ;) can explain it, I would be happy ;) thanks for you support!

  • How to get the ui:param value in Javabean

    - by mihaela
    Hello, I am learning facelets and Seam and I'm facing the following problem: I'm have 2 xhtml files, one includes the other and each one has its own Seam component as backing bean. I want to send and object to the included facelet and obtain that object in the backing bean corresponding to the included facelet. I'll take an example to explain better the situation: registration.xhtml with Seam component as backing bean Registration.java. In this class I have an object of type Person address.html with Seam component as backing bean Address.java. In this class i want to obtain the Person object from the Registration component and set the address. registration.xhtml includes the address.xhtml and passes an object using How to obtain this object in Address bean? Will be the same reference of the object from the Registration bean? is the solution of passing this object or there is another solution for that? (maybe f:attribute, but even in this case how do I obtain the object in bean) This example is simple and not necessarily realistic but I have a similar problem and I don't know how to solve it. Thanks in advance.

  • Tips on managing dependencies for a release?

    - by Andrew Murray
    Our system comprises many .NET websites, class libraries, and a MSSQL database. We use SVN for source control and TeamCity to automatically build to a Test server. Our team is normally working on 4 or 5 projects at a time. We try to lump many changes into a largish rollout every 2-4 weeks. My problem is with keeping track of all the dependencies for a rollout. Example: Website A cannot go live until we've rolled out Branch X of Class library B, built in turn against the Trunk of Class library C, which needs Config Updates Y and Z and Database Update D, which needs Migration Script E... It gets even more complex - like making sure each developer's project is actually compatible with the others and are building against the same versions. Yes, this is a management issue as much as a technical issue. Currently our non-optimal solution is: a whiteboard listing features that haven't gone live yet relying on our memory and intuition when planning the rollout, until we're pretty sure we've thought of everything... a dry-run on our Staging environment. It's a good indication but we're often not sure if Staging is 100% in sync with Live - part of the problem I'm hoping to solve. some amount of winging it on rollout day. So far so good, minus a few close calls. But as our system grows, I'd like a more scientific release management system allowing for more flexibility, like being able to roll out a single change or bugfix on it's own, safe in the knowledge that it won't break anything else. I'm guessing the best solution involves some sort of version numbering system, and perhaps using a project management tool. We're a start-up, so we're not too hot on religiously sticking to rigid processes, but we're happy to start, providing it doesn't add more overhead than it's worth. I'd love to hear advice from other teams who have solved this problem.
