  • Redirect in combination with a rewrite condition in htaccess

    - by Robbert van den Bogerd
    Hi all! I've got a cms-driven website, with no option to change the code. What I want to accomplish is creating friendly url's, using only apaches mod-rewrite engine. The problem is I'm creating an infinite loop, because I first redirect the original url (index.php?id=21) to a friendly one (/friendly/) and then rewrite the '/friendly' part back to 'id=21' I know there should be an extra condition or parameter to avoid looping in this case, but I can´t get one of the possible solutions to work. Here´s the code: RewriteCond %{query_string} ^id=21$ [NC] RewriteRule /* /peuterspeelzaal? [R=301,L] RewriteRule ^peuterspeelzaal$ index.php?id=21 [L]

  • Articles about replication schemes/algorithms?

    - by jkff
    I'm designing an hierarchical distributed system (every node has zero or more "master" nodes to which it propagates its current data). The data gets continuously updated and I'd like to guarantee that at least N nodes have almost-current data at any given time. I do not need complete consistency, only eventual consistency (t.i. for any time instant, the current snapshot of data should eventually appear on at least N nodes. It is tricky to define the term "current" here, but still). Nodes may fail and go back up at any moment, and there is no single "central" node. O overflowers! Point me to some good papers describing replication schemes. I've so far found one: Consistency Management in Optimistic Replication Algorithms

  • Very long tree control inside a <frame>

    - by ryancerium
    I have an tree control inside of a frame. It's quite tall, around 2000 pixels. Right now, we use the frame's scroll bars, which is mostly good. Unfortunately, when you select an item near the bottom of the list, the page reloads and the view goes back to the top of the list. I tried calling the tree control's ScrollNodeIntoView() function, but since we're not using the tree's scroll bars, it just thinks that it's displaying the full 2000 pixels and the control doesn't have its own scroll bar. I'm not much of an HTML guru, so I have two ideas, neither of which I know how to do. 1) Tell the frame to not to let the tree render all 2000 pixels and instead stay inside the viewable area. 2) Tell the tree to not render all 2000 pixels and instead stay within the viewable area. Setting the CSS height property on the within the frame doesn't do anything. Thanks.

  • Why does the VBA Editor open on its own sometimes?

    - by Kevin Finn
    I've created a small script in Outlook 2003 VBA that watches for new appointments, and sets them to tentative and no reminder as I create them. However, I now find that seemingly at random, the VBA editor will open itself. It doesn't happen when I actually use the new script, but it did happen this morning when I un-hibernated my laptop, for example. The editor doesn't pop up any runtime errors or highlight any lines in the script, it's just there as if I had pressed Alt-F11 to launch it. Sometimes I close other apps and see that it's been sitting back there for a while. This behavior has only been occurring since I created this new script. Any ideas why this would occur? Thanks!

  • Lackadaisical One-to-One between Char and Byte Streams

    - by Vaibhav Bajpai
    I expected to have a one-to-one correspondence between the character streams and byte streams in terms of how the classes are organized in their hierarchy. FilterReader and FilterWriter (character streams) correspond back to FilterInputStream and FilterOutputStream (byte stream) classes. However I noticed few changes as - BufferedInputStream extends FilterInputStream, but BufferedReader does NOT extend FilterReader. BufferedOutputStream and PrintStream both extend FilterOutputStream, but BufferedWriter and PrintWriter does NOT extend FilterWriter. FilterInputStream and FilterOutputStream are not abstract classes, but FilterReader and FilterWriter are. I am not sure if I am being too paranoid to point out such differences, but was just curious to know if there was design reasoning behind such decision.

  • How to improve performance

    - by Ram
    Hi, In one of mine applications I am dealing with graphics objects. I am using open source GPC library to clip/merge two shapes. To improve accuracy I am sampling (adding multiple points between two edges) existing shapes. But before displaying back the merged shape I need to remove all the points between two edges. But I am not able to find an efficient algorithm that will remove all points between two edges which has same slope with minimum CPU utilization. Currently all points are of type PointF Any pointer on this will be a great help.

  • summer experiment: GWT & python for a trading game- arch question

    - by sadhu_
    Hi, As a summer learning experiment, I'm thinking of coding up a web front end for a trading game i wrote in python, that generates share prices and random snippets of text. I am sort of struggling with how this should work on the back-end though. I'd rather have my GWT client page interact with the python share price generator, than to try and re-code it in java. I suppose i could use an sqlite db, and then use jdbc to pick up the prices, but i was wondering if there is a better way, for me to be able to poll some python script either from my client page, or from the serverside java code ? I found this python wrapper, but i'm not sure how i could use it though: http://code.google.com/apis/visualization/documentation/dev/gviz_api_lib.html Thanks.

  • Pressing "Home" in Vim on an Indented Line

    - by Reid
    I have a bad habit of using the 'home' key to go back to the beginning of a line. As I recently started using vim (and loving it!) I noticed that when I press the home key on a lined that is indented, it returns me to the very beginning of the line. In Notepad++ (the editor I used to use) it would return me to the beginning of the code on that line, right after the indent. Is there some way to replicate this behavior in vim? Usually, when I'm pressing home it's in the Insert mode for me to (usually) stick a variable there. I have set smartindent in my vimrc, with set noautoindent as a "tips" page told me to make sure to disable autoindent (although it didn't seem to be enabled in the first place - perhaps that option is extraneous.) Thanks in advance.

  • reading 2 lines from IniFile

    - by Lakkerw
    Trying again. On advice, adding the piece of code that I do understand. I am fine with the fact that I have to save 4 bits of information in two lines like so: IniFile.WriteString('TestSection','Name','Country'); IniFile.WriteString('TestSection','City','Street'); My question is more about loading this information back into the form. If in my IniFile I have saved for example the following code [TestSection] John=Uk London=barlystreet Mike=Spain Madrid=eduardostrata Emma=USA New York=1st Avenue Made up information in the IniFile. Added through the code above. Now my question is: How could I load for example, when I type in an edit box Mike, the rest of the belonging information.(Spain, Madrid,eduardostrata).

  • LINQ to SQL stored procedures with multiple results in Visual Studio 2008

    - by Jeremy
    I'm using visual studio 2008 and I've created a stored procedure that selects back two different result sets. I drag the stored proc on to a linq to sql dbml datacontext class, causing visual studio to create the following code in the cs file: [Function(Name="dbo.List_MultiSelect")] public ISingleResult<DataAccessLayer.DataEntities.List_MultiSelectResult> List_MultiSelect() { IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod()))); return ((ISingleResult<DataAccessLayer.DataEntities.List_MultiSelectResult>)(result.ReturnValue)); } Shouldn't the designer generate the code to use IMultipleResults? Or do I have to hand code that?

  • How to determine which side of a 3D plane is showing?

    - by Josh Santangelo
    This is a 3d n00b question. I'm working on a WPF control which implements the basics of Silverlight's PerspectiveTransform feature, allowing a 2D plane to be rotated on any of the three axes. It works pretty well. However I'm a little stuck on the math required to determine whether or not the back of the plane is showing. My naive code for figuring that out now is: bool isBackShowing = Math.Abs(RotationX) > 90 && Math.Abs(RotationY) < 90; if (!isBackShowing) { isBackShowing = Math.Abs(RotationX) < 90 && Math.Abs(RotationY) > 90; } However, this fails when the rotation is between +-270 and +-360 on either axis. The underlying transform is using a Quaternion object to do the actual rotation, and that has nice Axis and Angle properties, so I'm guessing I could just use that if I knew how.

  • MYOB Service Sales Import

    - by sjw
    I have developed an export file from our Job Management system that I want to be able to import into MYOB Accounting Plus v18.5. The file is generated without issue and I have included every single field to make it easy for upload (i.e. Match All matches every field) The problem I am having is no matter what I do, I cannot get the sales to import... Every time, no matter what I do or how I create the customer card comes back with: Error -190: Customer not found. Sale invoice not imported. I have tried matching using - co./Last Name, Card ID & Record ID and every time I get the same error. I have created a single customer with a simply Co./Last Name, Card ID & Record ID and still, when I try to import using these same fields exactly matched, I get the same error...

  • How do I send a file as an email attachment using Linux command line?

    - by Kit Roed
    I've created a script that runs every night on my Linux server that uses mysqldump to back up each of my MySQL databases to .sql files and packages them together as a compressed .tar file. The next step I want to accomplish is to send that tar file through email to a remote email server for safekeeping. I've been able to send the raw script in the body an email by piping the backup text file to mailx like so: $ cat mysqldbbackup.sql | mailx [email protected] cat echoes the backup file's text which is piped into the mailx program with the recipient's email address passed as an argument. While this accomplishes what I need, I think it could be one step better, Is there any way, using shell scripts or otherwise, to send the compressed .tar file to an outgoing email message as an attachment? This would beat having to deal with very long email messages which contain header data and often have word-wrapping issues etc.

  • Disabling FileSystemWatcher for specific updates?

    - by chaiguy
    Does anyone have any ideas how I can reliably disable a FileSystemWatcher object when my application makes changes to the files in the directory, so that I am only watching for external changes to the directory? I've tried setting EnableRaisingEvents to false immediately before performing a write and setting it back to true immediately after, but it seems this method is not reliable, and occasionally I still get the event firing. The only other thing I can think of is to wait a small amount of time after performing the write to let the OS finish up the modification of the directory before re-enabling the FSW, but that seems hackish and I don't like it. To add to the problem, the directory consists of potentially many files, the identities of which are beyond my knowledge and control, so I can't just wait for the event to fire for a specific file and then ignore it. There could be any number of FSW events firing after a single modification (because of the potentially many files getting updated).

  • Is a .Net membership database portable, or are accounts somehow bound to the originating Web site or

    - by Deane
    I have an ASP.Net Web site using .Net Membership with a SQL Server provider, so the users and roles are stored in the SQL tables created by Aspnet_regsql.exe. Is this architecture totally self-contained and portable, or are users in it somehow bound to the specific Web site on which they create their account? Put another way, if we create a bunch of users in dev or UAT, the back up and restore this database to another server, accessed under another domain name, should it still work just fine? We're seeing some odd behavior when we move the database, like users losing group affiliation and such, and I'm curious how portable and environment-agnostic this database really is. I have a sneaking suspicion that something is bound to the machine key or the domain.

  • DotNetOpenAuth: Webforms, Getting Started

    - by CccTrash
    I am trying to figure out how to get DotNetOpenAuth(http://www.dotnetopenauth.net/) working in my webforms app I don't understand where to begin. I have an OpenIDSelector on my Login.aspx that lets you choose google or Yahoo. You can choose one, then a popup comes up, and lets you login. Once you login the program hangs because it is trying to do something with a database??? Can't I just use some control(like the OpenIDSelector) and get back that the user was authenticated, get their ClaimedID and handle the rest myself? EDIT: Trying to get started with OpenID in Webforms? Go Here... http://www.dotnetopenauth.net/developers/code-snippets/programmatic-openid-relying-party/

  • Which UML tool can really round-trip java code?

    - by Geir Ove
    Hello, Many UML tools claim to do forward / reverse engineering of Java code. However, it turns out from prior experience, that few tools really work in this area. I haven't been doing Java projects for 3 years, and want to get up to date with the current status in this area. In Particular I am interested in Creating State Machine Skeletons from Diagram, be able to create hooks to my own code, and be able to reverse engineer the State Diagram back (Do not want to change the State Machine itself outside the Tool). Which UML tools works in this area? Enterprise Architecht? Visual Paradigm? Others? Geir Ove Norway

    As a beginning web developer, I try my best to clean up all the user inputs through checks and what not. However, today, I found out my website was hacked (I'll share their website on request) and it really made my wonder how did they do it. I'm in the process of getting my website back together. What should I do to prevent these things? Is there people I should talk to and ask how secure my website is? What can I do to to keep my website safe?

  • ADB crashes when device attached with eclipse

    - by user559592
    I am trying to get a development environment setup and having some problems with adb. I have eclipse installed and can create android projects and run/debug them in the emulator. But if I attached my device (HTC Evo) and try running on it, adb crashes. My device shows up so adb sees it. Everything is updated to the latest version. I even went and reinstalled my system so I had a clean start. It would still crash when I connect to the device. I restart adb but it just shuts right back down. Anyone have any suggestions on what I can do to fix this? Running on Windows 7.

  • Facebook API returning wrong unread thread count

    - by houbysoft
    I'm trying to query the thread FQL table to get all unread messages, and also the count of unread items in the thread. This is how I query the table: SELECT thread_id,updated_time,snippet,snippet_author,unread FROM thread WHERE folder_id=0 AND unread!=0 From reading the doc to which I linked above, it seems to me that unread should include the count of unread messages in the thread. However, I just tested the above call and Facebook gives me back a value of unread=1, despite the thread in question having 4 unread items. This is how the thread looks on facebook.com (notice the (4), showing that unread should be 4): This is what the API returns to me, which is wrong (notice the "unread":1): { "data":[ { "name":"messages", "fql_result_set":[ { "thread_id":"BLAH BLAH BLAH", "updated_time":1333317140, "snippet":"BLAH BLAH BLAH", "snippet_author":BLAH, "unread":1 } ] } ] } Am I doing something wrong, or is this a bug?

  • Getting Clipboard data in raw format in c++

    - by qwertymk
    I've been playing around with the windows clipboard. I noticed that you can only view the clipboard if you supply a format. I've seen programs that can dump the raw contents of the clipboard. Look at http://www.autohotkey.com/docs/misc/Clipboard.htm#ClipboardAll for an example of what I mean. Is there a way to do something similar, what I want to do is be able to back up the clipboard, manipulate it, then restore it when my program is done. I'm looking for a non-.net solution if that's actually a thing

  • Restoring web session in struts2

    - by bozo
    Hi, I have a classical scenario of a website and payment gateway integration, where the request for payment is sent to payment processor, and the payment processor calls back my application once it's done with some parameters I passed to it in the original request. Among parameters, we pass jsessionid and we expect that when the remote server makes request to our server (via customer browser redirect to our server) that the session will be the same as the session used to send the initial payment request. This does not happen, we have two different sessions, although the payment processor includes our original jsessionid in the request to us (https://blabla/?jsessionid=something). How should we go about recreating a session in struts2, in the only thing that connects the 'OLD' and 'NEW' session is the jsessionid in the request URL? Any ideas? Is this possible at all or is the 'OLD' session data deleted when the user moves away from our server onto a completely different domain of a payment processor with their data-entry form? This would explain our innability to recreate the session. Thanks a lot for your replies.

  • Changing a datatype solely for the purpose of Excel Export in Crystal Reports

    - by yeahumok
    I have a report that has several numerical fields. To fill a project requirement, i had to use the following formula: if {DataTable1.No of Investments}>9999 then '*****' else toText({DataTable1.No of Investments},0) Basically, if the number fed in is bigger than 9999 it turns into * on the report. Now, when i try to export into excel, not only is the data type for all fields, strings...but the * show up versus numbers. I was wondering if there was a way to re-cast this back into a numerical value SOLELY for the purpose of excel exportation so that i'd be able to use excel formulas as well as see numbers instead of asterisks. I'd only be doing data-only excel exports. Any ideas?
