• WPF 4.0 Font Rendering Issue

  - by Tom Allen

  I'm getting a weird rendering issue with WPF 4 applications in the way they render some of the text as it's stretching it and making it very narrow. .net 3.5: .net 4.0: At first I thought it could be a problem with the font, but I'm also seeing the same problem in the Blend 4 beta: I'm running XP SP3, Visual Studio 2010 Professional and everything's as up to date as it can be. I'm not noticing any such problems with Silverlight 4 apps I have built on the same machine... Anyone else seen this or know why it's happening?

• Visual Studio autoclean?

  - by kubal5003

  Hello, I have a solution with multiple projects - executable, library, and others(unimportant right now). Library contains EF entity classes and executable uses them. When I'm working on some code from the executable then every entity that I use is marked as an error and compiler says that I should check usings and references. Reference in the executable project is set to library project(not the dll itself). When I build the library project then everything gets back to normal, but when I start typing then it happens again. I could live with it, but intelli sense isn't working and that is quite a disadvantage. Any ideas?

• PHP AJAX mysql event calendar - UI for events spanning multiple days

  - by play

  I have built a PHP calendar system and have pretty much everything done but not sure how to deal with a UI issue involving how the events that stretched out over a couple of days. I want to be able to stretch an event that stretches over couple of days in a div that spans those days in the calendar. Basically I would like to know how to achieve what these guys have achieved with the event that stretches out from 21st to 22nd with the yellow div background. I have been trying to see how I can do it with PHP but I feel like I might be trying the wrong thing. Perhaps this is done with javascript?

• Ruby CMS/blog: Mephisto vs. Radiant

  - by Candidasa

  I'm looking for a blogging tool with some light CMS features in Ruby on Rails. I mainly want something simple, but configurable. I have no need for page snippets, etc. Just your basic main blog, very good (and easy) theme support, some nice sidebar stuff, a few static pages and MetaWeblog API support. I'm thinking of either using Mephisto or Radiant CMS (everything else seems half-baked or extremely lightweight at best): http://mephistoblog.com/ http://www.radiantcms.org/ Documentation for Mephisto seems very lacking and their site is a mess. I've also read some bad things about it's stability. Radiant seems more stable in comparison and has heaps of useful plug-ins. However, it isn't designed for blogging out of the box. That has to be added as almost an after thought. Creating a custom theme also seems more cumbersome with Radiant due to the sub-page/snippet feature. Which should I choose?

• Using 2 JQuery Autocomplete

  - by Trike

  Hi All! I am using the JQuery Autocomplete Plugin 1.1. When I try to add autocomplete to 2 inputs in this way: $("#object_ac").autocomplete("autocomplete_search.php", { extraParams: {object:1}, width: 160, selectFirst: false, minChars: 2 }); $("#id_norm_doc_ac").autocomplete("autocomplete_search.php", { width: 460, selectFirst: false, mustMatch: true }); $("#id_norm_doc_ac").result(function(event, data, formatted) { $("#id_norm_doc_add").val(data[1]); }); When #object_ac selected before #id_norm_doc_ac I get error after selecting one of suggestions in #id_norm_doc_ac: data is undefined [Break on this error] data = elementToString(data.documentElement, true); If I select #id_norm_doc_ac before other inputs, everything goes normal. Thanks in advance for any assistance!

• PHP/Cronjob: What is my Cronjobs problem?

  - by Marius

  Hello there, I have no idea whats going on. But I have a script that looks like this. Cron job refuses to run it: include_once 'class_lib/mime_mail/mimeDecode.php'; include_once 'class_lib/Mail/IMAPv2.php'; include_once 'inc-functions.php'; include_once "$_SERVER[DOCUMENT_ROOT]/class_lib/DbFuctioneer.php"; $dbFuctioneer = new DbFuctioneer(); Everything works well when I remove: $dbFuctioneer = new DbFuctioneer(); Even when DbFuctioneer() looks like this: <?php class DbFuctioneer { function dbCountMatches( $count) { return $count; } } Does Cron have a problem with Classes in his Jobs? Thank you for your time. Kind regards, Marius

• Asynchronous Silverlight WCF callback

  - by Matt

  I've created my own WCF service and I've successfully been able to talk to it via my Silverlight client. I ran into an interesting problem on my asynchronous callbacks though. When my callback is invoked, I can't update any UI controls with the dreaded invalid cross thread access Here's what my callback function looks like private void GetTimeCallBack( object sender, Talk.ClientBase<IService>.ClientEventArgs e ) { lblDisplay.Text = e.Object.ToString(); } A quick google search showed me that I have to do this instead. private void GetTimeCallBack( object sender, Talk.ClientBase<IService>.ClientEventArgs e ) { Dispatcher.BeginInvoke( () => lblDisplay.Text = e.Object.ToString() ); } Now everything works fine, but I wasn't expecting my callback to be running on a different thread. Will I always have to use the Dispatcher class in order to modify anything within my class or is this just limited to UI elements? I've not familiar with the Dispatcher class at all so I'm looking to understand it more.

• Extracting data from multiple servers SQL 2005 SSIS

  - by Raj

  I have created an SSIS package to connect to multiple SQL servers, create a database, a table and a stored procedure. The package also creates a job and schedules it to run every 5 minutes. The requirement is to collect performance metrics. I am using an ado object variable to get the server names and all the above tasks are in a for each loop and everything works fine. Now the problem: I need to create a data flow task, which will connect to each of these servers in turn, copy the performance metrics data over to a central server and purge the source table. I am unable to get this task to work. This task fails with "Unable to obtain Connection" error. Any help will be greatly appreciated. SQL Server Version : 2005 Thanks, Raj

• ExecutionEngineException thrown when loading native dll in c#

  - by Axarydax

  Hi there. I have a 32-bit .net application that uses a native 32-bit DLL via DllImport(). The native DLL is our internal file analysis library, and I need to use it as porting it to C# would be a problem if people update it (other software uses it). The problem is that when I try to execute any method in the native DLL I get a System.ExecutionEngineException thrown. In fact, I've reduced the managed application to a simple tester that just calls a native method, but it still fails. I am on 64-bit Windows 7, but that should not matter as I'm compiling everything as 32-bit binaries. What is also interesting, when I look at the native DLL in the Dependency Walker, it shows that it can't find msvcr90.dll - but when I open any other of our native DLLs in the Dependency Walker, it can find their referenced msvcr90.dll just fine. Can there by some wrongness in the compilation of native DLL that messss up its DLL references?

• How can a Firefox extension inject a local css file into a webpage?

  - by Evgeny Shadchnev

  I'm writing a Firefox extension that needs to inject a css file into webpages. The css file is bundled with the extension, so I can access it using a chrome url chrome://extensionid/content/skin/style.css I'm trying to inject css like this when the page is loaded: var fileref = document.createElement("link"); fileref.setAttribute("rel", "stylesheet"); fileref.setAttribute("type", "text/css"); fileref.setAttribute("href", "chrome://extensionid/content/skin/style.css"); document.getElementsByTagName("head")[0].appendChild(fileref); However, the css isn't loaded and Firebug shows 'Filtered chrome url' message instead of the file content, when I inspect the link element I created. If I try to load this css file from an external server, everything's fine. Is there are way to load a css file bundled with the extension?

• Why won't my UISearchDisplayController fire the shouldReloadTableForSearchString method when I enter

  - by Gorgando

  I've been following Apple's TableSearch code example, but it's not working for me and I think I'm doing everything the same way they did it. The method below should be fired whenever the user types anything into the search box, but it never gets fired for me, just on the sample app. I have the appropriate @interface ContactsTableVC : UITableViewController { in the header file. I'm not sure what I'm missing or where else to look. My NSLog never gets called. Thanks for the help! - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString searchScope:(NSInteger)searchOption { NSLog(@"The shouldreloadtableforsearchstring method has been called!"); [self filterContentForSearchText:searchString]; // Return YES to cause the search result table view to be reloaded. return YES; }

• Want to load jquery dialog from a different web-page

  - by Jake

  I'm a bit of a n00b with jquery so this one is probably an RTFM question: I'm writing an application to create a somewhat complex record for my client. Building the record requires doing a couple of server side searches inside a dialog. Right now I have everything framed up in 1 file (asp.net) and it's ok. But I can see as I add the business logic and the communication with the server this is going to get really ugly. I'm alreay putting most of the javascript in external files, but I'd like to move the HTML for the dialogs out too. How do I get the jquery dialog method to load the dialog body from the html files? Something like: getDialogHTML(dialogHolderDiv); <---magic goes here var dialogOptions = { ... }; $("#"+dialogHolderDiv).dialog(dialogOptions); $("#"+dialogHolderDiv).dialog('open'); any help will be apperciated .

• Nutch - how to crawl by small patches?

  - by Yurish

  Hi everyone! I am stuck! Can`t get Nutch to crawl for me by small patches. I start it by bin/nutch crawl command with parameters -depth 7 and -topN 10000. And it never ends. Ends only when my HDD is empty. What i need to do: Start to crawl my seeds with possibility to go further on outlinks. Crawl 20000 pages, then index them. Crawl another 20000 pages, index them and merge with first index. Loop step 3 n times. Tried also with scripts found in wiki, but all scripts i found don't go further. If i run them again, they do everything from beginning. And in the end of script i have the same index i had, when started to crawl. But, i need to continue my crawl. Some help would be very usefull!

• Rspec-rails doesn't seem to find my models

  - by sa125

  Hi - I'm trying out rspec, and immediately hit a wall when it doesn't seem to load db records I know exist. Here's my fairly simple spec (no tests yet). require File.expand_path(File.dirname(__FILE__) + '../spec_helper') describe SomeModel do before :each do @user1 = User.find(1) @user2 = User.find(2) end it "should do something fancy" end I get an ActiveRecord::RecordNotFound exception, saying it couldn't find User w/ ID=1 or ID=2, which I know for a fact exist. I set both test and development databases to point to the same schema in database.yml, so this shouldn't be database mixup. I also ran script/generate rspec after installing the gems (rspec, rspec-rails), and gem.config both environment.rb and test.rb. Any idea what I'm missing? thanks. EDIT Seems I was running the tests with rake spec:models, which emptied the db and thus no records were found. When I used % spec spec/models/some_model_spec.rb, everything worked as expected.

• zsh: command not found: ls

  - by ABach

  I'm having a rather strange problem with zsh. When I start up my shell, everything - functions, environment vars, aliases, etc. - all work fine. I've created the following function and sourced it in zsh: clean() { for i in /tmp/* do echo $i done } Running clean in the terminal works as expected, in that it prints out all the files in /tmp/. Afterward, however, trying any command - for example, ls - produces this: zsh: command not found: ls I have several other functions that work just fine, which leads me to believe that somehow, that loop is causing the problem. At any rate, this is very frustrating and I would sincerely appreciate the community's eyes. Thanks!

Any ideas?

  Hi, I have just migrated an older ASP solution to a windows 2008 server and everything works out fine except for using ADOX.Catalog to list all the worksheets in an uploaded xls file. I use the following code: <% Set objExcelCon = Server.CreateObject("ADODB.Connection") With objExcelCon .Provider = "Microsoft.ACE.OLEDB.12.0" .ConnectionString = "Data Source=" & strFilePath & "\" & strFileName & ";Extended Properties=Excel 12.0;" .Open End With Set objAdo = Server.CreateObject("ADOX.Catalog") ' Set ADOX activeConnection objAdo.activeConnection = objExcelCon ' Loop through tables (worksheets) For i = 0 To objAdo.Tables.Count - 1 response.Write objAdo.Tables(i).Name Next Set objExcelCon = Nothing Set objAdo = Nothing % When I run this i get no error message or anything. Anyone got any idea whats causing this? Best regards, Roy

• asn.1 parser in C/Python

  - by elventear

  I am looking for a solution to parse asn.1 spec files and generate a decoder from those. Ideally I would like to work with Python modules, but if nothing is available I would use C/C++ libraries and interface them with Python with the plethora of solutions out there. In the past I have been using pyasn1 and building everything by hand but that has become too unwieldly. I have also looked superficially to libtasn1 and asn1c. The first one had problems parsing even the simplest of files. The second has a good parser but generating C code for decoding seems too complex; the solution worked well with straightforward specs but choked on complex ones. Any other good alternatives I may have overlooked?

• Asp.Net 1 -> Asp.Net 2 upgrade - Machine.Config - unrecognized parameter

  - by Chris

  Hi All, I am working on upgrading a web app to asp.net 2 from 1. VS 2008 did its conversion things, and everything is building successfully and has been converted to a web application via the appropriate menu item in VS 2008. On launching the site using the Asp.net development server I am receiving a configuration error on the appsettings line in the machine config of Unrecognized attribute 'restartOnExternalChanges'. The app targets asp.net 2 in the projects properties in VS, and the error page indicates similar : Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053 The error message seems to indicate I am trying to run this in an asp.net 1 environment, but surely that isnt the case, and if so how do I rectify this. Any help would be appreciated Thanks,

• iframe as scriptaculous droppable

  - by Nathan

  I have a sortable list and an iframe on the same page. What I'm trying to do is define the <iframe> as a Droppable. Everything works with out errors but when I try to drag a sortable item across the Iframe it stops at the edge. ( if I move it slowly it seems works in firefox) The Iframe is set to DesignMode ="on" so covering it with a transparent element to act as the droppable does not seem applicable here. Anyone know of any other solutions or a better way to handle this?

• How do you convert date taken from a bash script to milliseconds in a Java program?

  - by Matt Pascoe

  I am writing a piece of code in Java that needs to take a time sent from a bash script and parse the time to milliseconds. When I check the millisecond conversion on the date everything is correct except for the month I have sent which is January instead of March. Here is the variable I create in the bash script, which later in the script I pass to the Java program: TIME=`date +%m%d%Y_%H:%M:%S` Here is the Java code which parses the time to milliseconds: String dt = "${scriptstart}"; java.text.SimpleDateFormat scriptStart = new java.text.SimpleDateFormat("MMDDyyyy_HH:mm:ss"); long start = scriptStart.parse(dt).getTime(); The goal of this statement is to find the elapsed time between the start of the script and the current system time. To troubleshoot this I printed out the two: System Time = 1269898069496 (converted = Mon Mar 29 2010 16:27:49 GMT-0500 (Central Daylight Time)) Script Start = 03292010_16:27:45 Script Start in Milli = 1264804065000 (Converted = Fri Jan 29 2010 16:27:45 GMT-0600 (Central Standard Time))
