• Code management in different projects with different svn repositories

  - by uzay95

  First of all I want to tell you what kind of system I have and I want to build on. 1- A Solution (has) a- Shared Class Library project (which is for lots of different solutions) b- Another Class Library project (which is only for this solution) c- Web Application project (which main part of this solution) d- Shared Web Service project (which also serves for different solutions) 2- B Solution (has) a- Shared Class Library project (which is for lots of different solutions) c- Windows Form Application project (which is main part of this solution) d- Web Service project (which also serves for different solutions) and other projects like that.... I am using xp-dev.com as our svn repository server. And I opened different projects for these items (Shared Class Library, Web Service project, Windows Form Application project, Web Application project, Another Class Library project) . I want to do the versioning of all these projects of course. My first question is, should I put each project(one solution) to one svn repository to get their revision number later on? Or should I put each of them to different svn repository and keep( write down) their correct version number that is used to publish/deploy every solution? If I use one svn for each project(Shared Class Lib, Web App, Shared Web Service....) how can I relate the right svn address and version on VS.2010 within the real solution? So, how do you manage your repositories and projects?

• How come Core i7 (desktop) dominates Xeon (server)?

  - by grant tailor

  I have been using this performance benchmark results to select what CPUs to use on my web server and to my surprise, looks like Core i7 CPUs dominates the list pushing Xeon CPUs into the bush. Why is this? Why is Intel making the Core i7 perform better than the Xeon. Are Desktop CPUs supposed to perform better than server grade Xeon CPUs? I really don't get this and will like to know what you think or why this is so. Also I am thinking about getting a new web server and thinking between the i7-2600 VS the Xeon E3-1245. The i7-2600 is higher up in the performance benchmark but I am thinking the Xeon E3-1245 is server grade. What do you guys think? Should I go for the i7-2600? Or is the Xeon E3-1245 a server grade CPU for a reason?

• Why can’t I create a database in an empty ASP MVC 2 project using Project->Add->New Item->SQL Server

  - by Dr Dork

  I'm diving head first into ASP MVC and am playing around with creating and manipulating a database. I did a search and found this tutorial for creating a database, however when I follow it, I get this error right at the start when trying to add a new database to my fresh, empty ASP MVC 2 project... A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) The only requirement the tutorial mentioned was SQL Server Express, but when I went to download it, it said it was already installed. I'm assuming it was part of the VS 2010 RC I installed and am running. So I don't know what else I need if I am missing something. This is all new to me, so I'm sure I'm missing something obvious here and after I'm done posting this question, I plan to do some more research into the topic of databases and how they work with ASP MVC. In the meantime, I was you could help me answer a couple high level questions... What am I missing/forgetting to do that is causing this error? Any suggestions for good resources/tutorials that focus on using databases with ASP MVC? I've done a lot of database programming in the past, so I'm familiar with the concepts of relational databases and the SQL language. I wish I could find a good resource for learning how to work with them in an ASP dev environment, as well as a good breakdown of all the related technologies used for working with them (i.e. LINQ to SQL). Thanks so much in advance for all your help! I'm going to start researching these questions right now.

• Can Visual Studio (should it be able to) compute a diff between any two changesets associated with a

  - by Hamish Grubijan

  Here is my use case: I start on a project XYZ, for which I create a work item, and I make frequent check-ins, easily 10-20 in total. ALL of the code changes will be code-read and code-reviewed. The change sets are not consecutive - other people check-in in-between my changes, although they are very unlikely to touch the exact same files. So ... at the en of the project I am interested in a "total diff" - as if there was a single check-in by me to complete the entire project. In theory this is computable. From the list of change sets associated with the work item, you get the list of all files that were affected. Then, the algorithm can aggregate individual diffs over each file and combine them into one. It is possible that a pure total diff is uncomputable due to the fact that someone else renamed files, or changed stuff around very closely, or in the same functions as me. I that case ... I suppose a total diff can include those changes by non-me as well, and warn me about the fact. I would find this very useful, but I do not know how to do t in practice. Can Visual Studio 2008/2010 (and/or TFS server) do it? Are there other source control systems capable of doing this? Thanks.

• ASP.NET javascript embed in template column

  - by Mahesh

  Hi, I am developing a web page in which a rad grid displays the list of exams. I included a template column which shows count down timer when the exam is going to expire. Code is as given below: <telerik:RadGrid ID="radGrid" runat="server" AutoGenerateColumns="false"> <MasterTableView> <Columns> <telerik:GridTemplateColumn HeaderText="template" DataField="Date"> <ItemTemplate> <script language="JavaScript" type="text/javascript"> TargetDate = '<%# Eval("Date") %>'; BackColor = "white"; ForeColor = "black"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; FinishMessage = "It is finally here!"; </script> <script language="JavaScript" src="http://scripts.hashemian.com/js/countdown.js" type="text/javascript"></script> </ItemTemplate> </telerik:GridTemplateColumn> </Columns> </MasterTableView> </telerik:RadGrid> I am giving DataTable as datasource to this grid. But my problem is , the template column is showing data only for the first record and the value taken is from the last row in the DataTable. For Ex: If I give data as given below, I can see 3 records but with only the first record displaying the counter with last value(10/10/2010 05:43 PM). 02/02/2011 01:00 AM 08/09/2010 11:00 PM 10/10/2010 05:43 PM Could you please help in this?? Thanks, Mahesh

• Odd Things of ASP.NET MVC Deployment on IIS 6

  - by misaxi

  Recently, I am a bit interested in the deployment of ASP.NET MVC application on IIS6 because Phil Haack posted an easier way to deploy ASP.NET MVC application on ASP.NET 4. So I decided to see how different version of ASP.NET MVC works on different version of ASP.NET. First off, I created an ASP.NET MVC 2 project in Visual Studio 2010 and deploy it to IIS 6 on Windows Server 2003 (only .NET framework 3.5 installed). I set the application to run in ASP.NET 2.0 and no extra stuff. Because I just wanted to see what sort of error would occur. And as expected, some error was reported as following. Then, I set the Copy Local attribute of System.Web.Mvc assembly to true as following and deploy again. As a result, the application ran smoothly. I had read tons of materials talked about the mess of deploying MVC application on IIS 6. And I did fight to tackle the deploying issues in my previous project. At least, if had used Extensionless Url in your application, you should have configured wildcard mapping in IIS. But in this case, I even didn’t have chance to do so. What the heck was going on exactly? Did I discover a new continent?

• setreg.exe for Windows 7

  - by victoriah

  I want to use setreg.exe (http://msdn.microsoft.com/en-us/library/aa387700(VS.85).aspx) to disable the certificate revocation check. However, it's based on an older version of .NET than what I have. Microsoft says it's shipped with the older .net SDK, and when I download that, try to install, it says something like 'can't install SDK without .net 1.1'. In the article linked it says for newer versions I should use SignTool, but SignTool does not appear to have the function I need . Is it possible to either - a) find a tool that can perform the function I need that doesn't need me to install the older .NET b) get setreg.exe without downloading the SDK or do I need to install the older .NET on my machine? And if the latter is the case, what do I need to do to install an older .NET? Will it overwrite my current .NET? Thanks,

• Is there a difference in page fault rates between CPU bound and I/O bound processes?

  - by user198864

  I was thinking, should there be any difference in expectation of the page fault rate on CPU-bound vs I/O bound processes? At first I thought maybe we could, since CPU-bound processes would likely be using more memory accesses per time quantum, so I expect it would move from locality to locality faster. At the same time, the CPU-bound process is probably given a larger working set... but this doesn't affect the fault overhead as it hits a new locality IF this wasn't pre-paged in. Is there actually any real difference in the page fault rates or am I just musing about something nonexistent? And if there is, how would it impact a real-world OS like linux?

• How do I fix font corruption in Google Chrome 9.0.597.44beta in Windows XP?

  - by snicker

  I am not sure what is causing this problem, but I think it is related to unicode problems. Google Chrome, seemingly out of nowhere a month ago, stopped rendering unicode characters in certain fonts. IE this ?_? Looks fine in some fonts, but looks like this in others. Renders fine in other browsers. Most recently, I visited the FourSquare website and have complete font corruption. Here is IE vs Chrome Full Size What gives? Has anyone else seen this? How can I fix it?

• Selecting rows with references across tables in SQLite 3

  - by ChristianK

  Hey there, I have a problem with a SQLite photo/album database. The database contains 3 tables: Albums id name hide -------------------------- 1 Holiday 2010 1 2 Day Trip 0 Photos id file ----------------- 1 photo1.jpg 2 photo2.jpg 3 photo3.jpg 4 photo4.jpg Relation (connects photos with albums) album photo ----------------- 1 1 1 2 2 3 2 1 A photo can be assigned to zero, one or several albums. Each album has a column 'hide' that indicates, whether the photos of this album should be ignored. I'm trying to find a SELECT query that returns all photos that are not assigned to an album + all the photos that are in albums which are not hidden (i.e. that have their 'hide' value set to 0). I came up with a query that selects photos in visible albums, but I don't know how to include the photos that are not assigned to an album. SELECT file FROM photos, albums, relation WHERE photos.id = relation.photo AND albums.id = relation.album AND albums.hide = 0 This query returns photo3.jpg and the required result would be photo3.jpg photo4.jpg because photo4.jpg is not assigned to album in the Relation table. Do you know how to solve this? Thank you very much for your help!

• How to import properties of an external API into Script#

  - by AndrewDotHay

  I'm using Script# inside Visual Studio 2010 to import the API for the HTML5 Canvas element. Its working great for things like FillRect(), MoveTo(), LineTo() and so on. I've declared the following interface and then I can code against it in C#. Then, Script# converts it to JavaScript nicely. public interface CanvasContext { void FillRect(int x, int y, int width, int height); void BeginPath(); void MoveTo(int x, int y); void LineTo(int x, int y); void Stroke(); void FillText(string text, int x, int y); } I want to include the StrokeStyle property that takes a simple string. The following interface definition produces a prefix in the JavaScript, which causes it to fail. string StrokeStyle { get; set; } string Font { get; set; } The previous property will create this JavaScript: ctx.set_strokeStyle('#FF0'); How can I get Script# to generate the simple assignment properties of the canvas context without the get_/set_ prefix?

• For web development which is more important - CPU and Graphics card OR Ram and SSD Harddrive?

  - by adam

  Buying a laptop is always hard work and questions about specific models dont age well on forums. A popular dilema (especially with apple macbooks) is whether to spend more for a faster cpu and graphics card but settle for standard ram and hd OR drop down and spend the savings on more ram and a faster harddrive such as a ssd. Im wondering for web development i.e. ide, unit tests, photoshop work and some user testing screen capturing now and again what would provide better performance. ( No games, music production or spielberg standard video editing.) For examples sake the current apple lineup for their 15inch macbookpros. 2.66 cpu i7 4gb ram 5400rpm drive 4gig ram vs 2.4 cpu i5 8gb ram 124gb sdd roughly the same price.

• Execute files included in Resource folder

  - by Sumeet Pujari

  In WPF application where I have included some files in resources, I want to execute them on a button click. How do I specify a path in Process.Start(). private void button1_Click_2(object sender, RoutedEventArgs e) { Process.Start("test.txt"); } Or is there any other way? private void button1_Click_2(object sender, RoutedEventArgs e) { string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + @"\test.txt"; if (File.Exists(path)) { Process.Start(new ProcessStartInfo(path)); } else { MessageBox.Show("No file found"+path); } I added a message box and it showed No files found. :( EDIT: I Tried to check the path after publishing and this what i got. No File Found With a Path - C:\Users\Administrator\AppData\Local\Apps\2.0... test.txt Before I published the Application I got a path which id No File Found at ..project..\bin\Debug\test.txt which is obvious since my Resource file not included there its Under a Resource Folder and not Debug when i add a test file in debug it open without any problem. Can someone Help throwing some light on this case. EDIT: I want to open a file from Resource directory @ C:\Users\Administrator\Documents\Visual Studio 2010\Projects\FastFix\FastFix\Resources Which would be included in my project when i am going to publish it is going to run as a standalone application without installation.

• Symfony 1.4 Form Value change after getValues()

  - by bertzzie

  Hi, I've got some problem with symfony form value (i guess it's the clean value, but not so clear yet). Here's the problem : I got a sfFormDateJQueryUI widget setup like this in my form : $this->setWidgets(array( 'needDate' => new sfWidgetFormDateJQueryUI(), )); $this->setValidators(array( 'needDate' => new sfValidatorDate(array( 'required' => true, 'date_format' => '/^[0-9]{2}\/[0-9]{2}\/[0-9]{4}$/', 'date_output' => 'd/m/Y' )), )); Then when i submit, say 26/06/2010, it turns out right in the HTTP Header (viewed via Firebug) and $request (i just print it). But after i get the value via $formVal = $form->getValues(); the date value in $formVal["needDate"] become today's date (03/06/2010). I really don't understand, and after checking in the API documentation it says that the getValues will return the 'cleaned' value. Is that because of it ? I don't understand what's 'clean'. Thanks before..

• Best way to create a collection of a class

  - by smartins

  I'm trying to create some classes that allow me to retrieve and manipulate a set of backups my application will create and manage. I've come up with the following code (not tested yet), but I'm not sure if it's the best way of accomplishing this or if there's any easier/better way. I'm using Delphi 2010. I have a class that holds the backup details (TBackupItem), then I need to have a class that will hold a collection of TBackupItem and finally I'll have a class that manages the reading and writing of backups and also exposes a property that accesses the collection of TBackupItem. type TBackupItem = class private FBackupProgram: string; FBackupProgramVersion: string; // There are more variables and properties but for the sake of simplicity I've listed only two public property BackupProgram: string read FBackupProgram write FBackupProgram; property BackupProgramVersion: string read FBackupProgramVersion write FBackupProgramVersion; end; TBackupsList = class(???) private // This class will hold a list of TBackupItem. What should I use to accomplish this? end; TBackupsManager = class(TObject) private FBackups: TBackupsList; public property Backups: TBackupsList read FBackups write FBackups; end; Do you guys have any comments and/or examples on the best way of accomplishing this? Thanks!

• Google maps later traffic

  Google maps has this feature of showing you how long it will take to get somewhere based on current traffic. But what about history, or asking for a prediction of how long it will take to get somewhere, during rush hour, for example? So, how long will it take to get there on this route if I leave at 5, vs how long it will take if I leave at 3. (A difference of 30 minutes on the road sometimes!) If google maps doesn't provide this service, iis there anywhere that does?

• Remove the hash after Ajax loading (I'm ajaxing wordpress 8-) )

  Hi everybody, I followed this great tutorial to"ajax" my blog:http://www.deluxeblogtips.com/2010/05/how-to-ajaxify-wordpress-theme.html But it creates some problems and I think the problem is in the hash that ajax creates. So, after the content is loaded, how can I remove the hash from the url? I copy my code here: jQuery(document).ready(function($) { var $mainContent = $("#content"), siteUrl = "http://" + top.location.host.toString(), url = ''; $(document).delegate("a[href^='"+siteUrl+"']:not([href*=/wp-admin/]):not([href*=/wp-login.php]):not([href$=/feed/]):not([href*=/go.php]):not(.comment-reply-link)", "click", function() { location.hash = this.pathname; $('html, body').animate({scrollTop:0}, 'fast'); return false; }); $("#searchform").submit(function(e) { location.hash = '?s=' + $("#search").val(); e.preventDefault(); }); $(window).bind('hashchange', function(){ url = window.location.hash.substring(1); if (!url) { return; } url = url + " #inside"; $mainContent.html('<div id="loader">Caricamento in corso...</div>').load(url, function() { //$mainContent.animate({opacity: "1"}); scriptss(); }); }); $(window).trigger('hashchange'); }); Thank all very much!

• How to correctly pass a float from C# to C++ (dll)

  - by RavelT

  I'm getting huge differences when I pass a float from C# to C++. I'm passing a dynamic float wich changes over time. With a debuger I get this: c++ lonVel -0.036019072 float c# lonVel -0.029392920 float I did set my MSVC++2010 floating point model to /fp:fast wich should be the standard in .NET if I'm not mistaken, but this didnt help. Now I cant give out the code but I can show a fraction of it. From C# side it looks like this: namespace Example { public class Wheel { public bool loging = true; #region Members public IntPtr nativeWheelObject; #endregion Members public Wheel() { this.nativeWheelObject = Sim.Dll_Wheel_Add(); return; } #region Wrapper methods public void SetVelocity(float lonRoadVelocity,float latRoadVelocity){Sim.Dll_Wheel_SetVelocity(this.nativeWheelObject,lonRoadVelocity,latRoadVelocity);} #endregion Wrapper methods } internal class Sim { #region PInvokes [DllImport(pluginName, CallingConvention=CallingConvention.Cdecl)] public static extern void Dll_Wheel_SetVelocity(IntPtr wheel,float lonRoadVelocity,float latRoadVelocity); #endregion PInvokes } } And in C++ side @ exportFunctions.cpp: EXPORT_API void Dll_Wheel_SetVelocity(CarWheel* wheel,float lonRoadVelocity,float latRoadVelocity){ wheel->SetVelocity(lonRoadVelocity,latRoadVelocity);} So any sugestions on what I should do in order to get 1:1 results or atleast 99% correct results.

• pass parameter from $.post() callback to outer variable

  - by Nazmin

  basically i want to hold a parameter that retrieve value from $.post() call like this: init = function(){ var lastpage = getLastPage(); } function getLastPage(){ $.post("getInfo.php",{ last: "yes" }, function(data){ setLast(data.last); },'json'); return function setLast(data){ return data; } } so when reach at last post (last page) i should check with lastpage variable that has a value returned from getLastPage() function. I'm pretty blur with javascript pointer and all. Please help guys. update (20/4/2010): I've done the other way around, like this: init = function(){ getLastPage(); if((page+1) == $("#lastpage").val()){ alert("this is last post"); }else{ page++; //get info and display to the page here } } function getLastPage(){ $.post("getInfo.php",{ last: "yes" }, function(data){ $("#lastpage").val(data.last); },'json'); } first run the function to temporarily store the value in hidden input tag (lastpage) and then grab the value again to check it whenever i click forward button. if you all have more appropriate way please tell me.
