• [VB.Net] System.IO will copy files, but fails to update destinations file attributes

  - by CFP

  Hello, I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file. If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal) IO.File.Copy(Source, Destination, True) IO.File.SetAttributes(Destination, IO.FileAttributes.Normal) IO.File.SetLastWriteTimeUtc(Destination, IO.File.GetLastWriteTimeUtc(Destination).AddHours(1)) IO.File.SetAttributes(Destination, IO.File.GetAttributes(Source)) I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well. I'm totally puzzled: I've checked, and file attributes are set to 128 (ie. Normal) successfully. The problem seems to be with the very SetLastWriteTimeUtc. But what is it? Any ideas? Thanks a lot!

• Codeigniter: Retrieving a variable from Model to use in a Controller

  - by Craig Ward

  Hi, I bet this is easy but been trying for a while and can't seem to get it to work. Basically I am setting up pagination and in the model below I want to pass $total_rows to my controller so I can add it to the config like so '$config['total_rows'] = $total_rows;'. function get_timeline_filter($per_page, $offset, $source) { $this->db->where('source', $source); $this->db->order_by("date", "desc"); $q = $this->db->get('timeline', $per_page, $offset); $total_rows = $this->db->count_all_results(); if($q->num_rows() >0) { foreach ($q->result() as $row) { $data[] = $row; } return $data; } } I understand how to pass things form the Controller to the model using $this->example_model->example($something); but not sure how to get a variable from the model?

• Tellago releases a RESTful API for BizTalk Server business rules

  - by Charles Young

  Jesus Rodriguez has blogged recently on Tellago Devlabs' release of an open source RESTful API for BizTalk Server Business Rules.   This is an excellent addition to the BizTalk ecosystem and I congratulate Tellago on their work.   See http://weblogs.asp.net/gsusx/archive/2011/02/08/tellago-devlabs-a-restful-api-for-biztalk-server-business-rules.aspx   The Microsoft BRE was originally designed to be used as an embedded library in .NET applications. This is reflected in the implementation of the Rules Engine Update (REU) Service which is a TCP/IP service that is hosted by a Windows service running locally on each BizTalk box. The job of the REU is to distribute rules, managed and held in a central database repository, across the various servers in a BizTalk group.   The engine is therefore distributed on each box, rather than exploited behind a central rules service.   This model is all very well, but proves quite restrictive in enterprise environments. The problem is that the BRE can only run legally on licensed BizTalk boxes. Increasingly we need to deliver rules capabilities across a more widely distributed environment. For example, in the project I am working on currently, we need to surface decisioning capabilities for use within WF workflow services running under AppFabric on non-BTS boxes. The BRE does not, currently, offer any centralised rule service facilities out of the box, and hence you have to roll your own (and then run your rules services on BTS boxes which has raised a few eyebrows on my current project, as all other WCF services run on a dedicated server farm ).   Tellago's API addresses this by providing a RESTful API for querying the rules repository and executing rule sets against XML passed in the request payload. As Jesus points out in his post, using a RESTful approach hugely increases the reach of BRE-based decisioning, allowing simple invocation from code written in dynamic languages, mobile devices, etc.   We developed our own SOAP-based general-purpose rules service to handle scenarios such as the one we face on my current project. SOAP is arguably better suited to enterprise service bus environments (please don't 'flame' me - I refuse to engage in the RESTFul vs. SOAP war). For example, on my current project we use claims based authorisation across the entire service bus and use WIF and WS-Federation for this purpose.   We have extended this to the rules service. I can't release the code for commercial reasons :-( but this approach allows us to legally extend the reach of BRE far beyond the confines of the BizTalk boxes on which it runs and to provide general purpose decisioning capabilities on the bus.   So, well done Tellago.   I haven't had a chance to play with the API yet, but am looking forward to doing so.

• Database of common translated phrases for localization?

  - by richardtallent

  I'd like to localize my app into a few other languages, all of which I can barely order a drink in. Does anyone know of an online resource for translations of common software menu options, messages, etc. into other languages? Given the number of developers (both OSS and closed-source) that deal with localization, and the overlap of resource strings between, it seems like a pretty obvious fit for a wiki or open source package, but I can't seem to find anything like this. I could try to mine the Windows resource files or dig around in resource strings in robust OSS apps like Firefox, but I suspect I'm not the first person to think of this and surely there is a site that I'm just not finding yet. Update: since nothing exists like this that I could find, I started a feeble attempt at an open-source string library. It's just a boilerplate Google spreadsheet now, so if you want to contribute, please go here: http://www.xark.org/

• What's the cause of (and treatment for) this java MySQL exception?

  - by justkevin

  I'm getting the following exception when executing the first preparedstatement after a period of inactivity: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 2,855,054 milliseconds ago. The last packet sent successfully to the server was 123 milliseconds ago. at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at com.mysql.jdbc.Util.handleNewInstance(Util.java:406) at com.mysql.jdbc.SQLError.createCommunicationsException(SQLError.java:1074) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:3052) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:2938) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3481) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1959) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2109) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2648) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:2077) at com.mysql.jdbc.PreparedStatement.executeQuery(PreparedStatement.java:2228) This only shows up if my application hasn't communicated with MySQL recently. Subsequent queries execute normally. I suspect it's some kind of timeout issue, but the periods of inactivity are way below the 8 hour timeout for MySQL. Any suggestions?

• Python: Decent config file format

  - by miracle2k

  I'd like to use a configuration file format which supports key value pairs and nestable, repeatable structures, and which is as light on syntax as possible. I'm imagining something along the lines of: cachedir = /var/cache mail_to = [email protected] job { name = my-media frequency = 1 day source { from = /home/michael/Images source { } source { } } job { } I'd be happy with something using significant-whitespace as well. JSON requires too many explicit syntax rules (quoting, commas, etc.). YAML is actually pretty good, but would require the jobs to be defined as a YAML list, which I find slightly awkward to use.

• Does Team Foundation Server supports Checkpoints?

  - by marco.ragogna

  My dev team used in the past MKS Source Integrity source control and we are not evaluating to migrate to TFS 2010. Some concepts and meaning are a bit different and we need sometime to learn how to do the same things we do before in TFS or how to change our approach. First of all, we used to do Checkpoints for each software release. MKS in this case does a snapshot of all source code files. You can later compare different checkpoints to see the code differences, or extract a whole checkpoint as a build. Does TFS have a similar feature? Do you know where can I read something about it? Thanks in advance, Marco

• Article Sharing &ndash; Windows Azure Memcached Plugin

  - by Shaun

  I just found that David Aiken, a windows azure developer and evangelist, wrote a cool article about how to use Memcached in Windows Azure through the new feature Azure Plugin. http://www.davidaiken.com/2011/01/11/windows-azure-memcached-plugin/ I think the best solution for distributed cache in Azure would be the Windows Azure AppFabric Caching but since it’s only in CTP and avaiable in the US data center David’s solution would be the best. Only one thing I’m concerning about, is the stability of windows verion Memcached.

• WPF - 'Relational' Data in XAML Using DataContext

  - by Andy T

  Hi, Say I have a list of Employee IDs from one data source and a separate data source with a list of Employees, with their ID, Surname, FirstName, etc. Is it possible in XAML only to get the Employee's name from the second data source and display it next to the ID, using something like this (with the syntax corrected)?.. <TextBlock x:Name="EmployeeID" Text="{Binding ID}"></TextBlock> <TextBlock Grid.Column="1" DataContext="{StaticResource EmployeeList[**where ID = {Binding ID}**]}" Text="{Binding Surname}"/> I'm thinking back to my days using XML and XSLT with XPath to achieve the kind of thing shown above. Is this kind of thing possible in XAML? Or do I need to 'denormalize' the data first in code, into one consolidated list? It seems like it should be possible to do this simple task using XAML only, but I can't quite get my head around how you would switch the DataContext correctly and what the syntax would be to achieve this. Is it possible, or am I barking up the wrong tree? Thanks, AT

• shared library in C

  - by sasayins

  Hi, I am creating a shared library in C but don't know what is the correct implementation of the source codes. I want to create an API like for example, printHello, int printHello( char * text ); This printHello function will call another function: In source file, libprinthello.c, void printHello( char * text ) { printHi(); printf("%s", text); } Since this printHello function is the interface for the user or application: In header file libprinthello.h, extern void printHello( char * text); Then in the source file of the printHi function, printhi.c void printHi() { printf("Hi\n"); } Then my problem is, since printHello is the only function that I want to expose in the user, what implementation should I do in printHi function?

• SSIS web service task parsing result.

  - by dbengals

  I have an ssis (2005) package that uses the web service task to download to a file destination. The file contains a string of xml data. After downloaded the file looks like this. <?xml version="1.0" encoding="utf-16"?> <string>--here is XML data with escaped characters--</string> My thought was I could then use the XML source data flow source to pull the <string> data, but when I set this up the XML source will not read the <string> as a column. It will generate an xsd and it seems normal, but no luck seeing the column. Any ideas on getting this to work? Or would there be a better way to pull the data within the file generated from the web service? Thanks.

• Linux Kernel - programmatically retrieve block numbers as they are written to

  - by SpdStr

  I want to maintain a list of block numbers as they are physically written to using the linux kernel source. I plan to modify the kernel source to do this. I just need to find the structure and functions in the kernel source that handle writing to physical partitions and get the block numbers as they write to the physical partition. Any way of doing this? Any help is appreciated. If I can find where the kernel is actually writing to the partitions and returning the block numbers, that'd work.

• Generating JavaDoc style documentation

  - by Walter White

  Hi all, I would like to generate a report similar to JavaDoc so that you can real easily click on a test, result, and source. I am running HtmlUnit tests so I will have the result (html), source (request, headers, parameters, etc.), stack trace all visible so a developer or qa can go back later to review this to see what went awry. So, in the left frame, the tests will be listed along with the group they were a part of (similar to packages in javadoc). In the right frame, the results will be presented along with the source and stack trace. How can I achieve this? The HtmlUnit tests are part of the project and not a stand-alone plugin if that matters. Thanks, Walter

• Aptana Studio 2.0: How to checkout SVN Project to SFTP remote dir?

  - by Brian Lacy

  If you're familiar with the excellent Aptana Studio IDE, you know it's based on Eclipse. You also know it comes pre-packaged with SFTP capability. I need to work on a remote server, where I have Apache installed; SFTP is ideal for this. I've installed the Subclipse plugin, and I can access and checkout projects from the Repo. I can create a new project from SVN source, which will download all the source to my chosen workspace or a specified location. But I can't figure out a way to combine these features! I need to create a Project on a remote server via SFTP but I need to link the source to a repository. Is there any way to do this?
