• How to get the client ip address in ASP.Net MVC?

  - by melaos

  hi guys, i'm totally new to the asp.net mvc stack and i was wondering what happened to the simple Page object and the Request ServerVariables object? basically what i wanted to do is to pull out the client's pc ip address. but i fail to understand how the current MVC structure has changed all of this. as far as i can understand, most of the variable object has been replaced by the HttpRequest variants? anybody care to share some resources? really a sea of stuff to learn in the asp.net mvc world :) thanks.

• SharePoint User Profile Search

  - by lucasstark

  Is there a way to search profiles in MOSS from the object model? I need to search for profiles that have a certain value set on their profile and then perform some action for them. I need to write some c# code that can search the profiles database and return the matching profiles. Basically, List of Profiles = Select Profiles From Profile Store Where Profile Property Value = SomeValue I'm trying to avoid the following: private IEnumerable<UserProfile> SearchProfiles(string value) { ServerContext serverContext = ServerContext.GetContext(SPContext.Current.Site); UserProfileManager profileManager = new UserProfileManager(serverContext); foreach (UserProfile profile in profileManager) { if ((string)profile["MyProp"].Value == value) { yield return profile; } } }

• How to automatically include generated source files into a C# project in Visual Studio?

  - by Charles Prakash Dasari

  I have a situation where I need to generate a bunch of C# code files in a prebuild step of a project and include the generated files into the current project for compilation. Is there a way to do this cleanly without having to muck with the project file every time the prebuild step is run? My solution should work for both IDE based build and a Team Build based on MSBuild. Since both are MSBuild based, I suspect there won't be much difference; but wanted to call it out. Any help is greatly appreciated, thanks!

• Repeated Scene Trees (Java3d / OpenGL)

  - by Jim

  Hello, I want to make a 3d scene that loops around on its self. That is to say, if you keep going in any direction, you will loop back to the other side. My current implementation is so bad, it's embarrassing to admit to it. I redraw the each change twenty-seven times, to make a 3x3x3 scene cube. When the user reaches the end of the middle cube, I jump them over to the other side. Maintaining consistency (let alone performance) is a nightmare. Total Disaster. This doesn't seem like it would be an unusual request, so I'm wondering if anyone knows of a more legit solution. Thanks!

Many thanks, Galen

• Backup & recovery of multiple MySQL databases (InnoDB & MyISAM)

  - by Cymon

  I am working on nightly and hourly backups of MySQL Databases. There are multiple MySQL databases which are either InnoDB or MyISAM (Note: Each database is either InnoDB or MyISAM for a reason). With the 2 different types I want to make sure I am grabbing everything that is needed for backup and recovery. Here is my current plan Nightly -mysqldump of each DB which is stored locally and remotely. Hourly -flush binary logs and store them locally and remotely. Weekly -expire binary logs older than a week. I feel like I am grabbing everything that is needed for the MyISAM databases but I am concerned about the InnoDB databases and the log files (ib_logfile0, ib_logfile1, ibdata1) they create. Should I backup these files? Nightly? Hourly? Both? Do I really need them if I am already doing the above nightly and hourly backups?

• Changing a form's action attribute in IE?

  - by Jonatan Littke

  Hey. I'm trying to set a hash value in a form's action, to keep it when the form is submitted. Firefox allows me to update the hash and redirects accordingly, but IE doesn't. I initially thought this was related to IE not allowing hash values in the action attribute at all, but it seems I can't dynamically set the action at all in IE - with a hash or not? Is that right? I'm using the following jQuery: $("#options-form").attr('action', '#' + hash); To update: <form id="options-form" action="" method="get"> (On a sidenote, this wasn't needed in Firefox, because FF appears to preserve the current hash if it was only the GET params that changed.)

• C/C++/Assembly Programatically detect if hyper-threading is active on Windows, Mac and Linux

  - by HTASSCPP

  I can already correctly detect the number of logical processors correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyperthreading is supported AND active (or enabled if you prefer) and if so divide the number of logical processors by 2 to determine the number of physical processors. Perphaps I should provide an example: A quad core Intel CPU's with hyperthreading enabled has 4 physical cores, yet 8 logical processors (hyperthreading creates 4 more logical processors). So my current function would detect 8 instead of the desired 4. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED?

• Invalidating ASP.NET FormsAuthentication server side

  - by Rob Walker

  I am experimenting with FormsAuthentication (using ASP.NET MVC2) and it is working fairly well. However, one case I can't work out how to deal with is validating the user identity on the server to ensure it is still valid from the server's perspective. eg. User logs in ... gets a cookie/ticket Out of band the user is deleted on the server side User makes a new request to the server. HttpContext.User.Identity.Name is set to the deleted user. I can detect this fine, but what is the correct way to handle it? Calling FormsAuthentication.SignOut in the OnAuthorization on OnActionExecuting events is too late to affect the current request. Alternatively I would like to be able to calls FormsAuthentication.InvalidateUser(...) when the user is deleted (or database recreated) to invalidate all tickets for a given (or all) users. But I can't find an API to do this.

• Firefox Extension needs to get cookie from PHP redirected external page.

  - by Tyler

  I am writing a firefox extension that interacts with a JSON server interface. I receive a url to the server which then redirects to the client site that provides the cookie. I need to be able to set this cookie in the users browser without physically loading it in the browser. Is this possible through an AJAX call? I tried using a hidden iframe, however firefox does not seem to like a php redirect in the iframe. My current solution is to load the site in a second tab that never gains focus and then auto close it when the cookie is set. This is very messy and would prefer something more streamlines. Any thoughts?

• How do I retrieve the zero-based index of the selected option in a select box?

  - by Ben McCormack

  Let's say I have the following in my HTML code: <select name="Currency" id="Currency"> <option value="0.85">Euro</option> <option value="110.33">Japanese Yen</option> <option value="1.2">Canadian Dollars</option> </select> Using jQuery, I can use $("#Currency").val() to give me the selectd value, and I can use $("#Currency :selected").text() to get the selected text. What do I need to do to get the zero-based index (in this case, 0, 1, or 2) of the current selection?

• Writing a rails validator with integer

  - by user297008

  I was trying to write a validation for Rails to ensure that a price entered on a form was greater than zero. It works…sort of. The problem is that when I run it, val is turned into an integer, so it thinks that .99 is less than .1. What's going on, and how should I fix the code? class Product < ActiveRecord::Base protected def self.validates_greater_than_zero(*attr_names) validates_each(attr_names) do |record, attr, val| record.errors.add(attr, "should be at least 0.01 (current val = #{val.to_f})") if val.nil? || val < 0.01 end end public validates_presence_of :title, :description, :image_url validates_numericality_of :price validates_greater_than_zero :price end

• MVVM with animations (should I use VisualStateManager?)

  - by kennethkryger

  I've got a View.xaml with the following set in Resources-section: <DataTemplate DataType="{x:Type ViewModels:MyFirstViewModel}"> <Views:MyFirstView Content="{Binding}" /> </DataTemplate> <DataTemplate DataType="{x:Type ViewModels:MySecondViewModel}"> <Views:MySecondView Content="{Binding}"/> </DataTemplate> In the content of the View.xaml I have: <!-- SelectedMyViewModel is either set to MyFirstViewModel or MySecondViewModel --> <ContentControl Content="{Binding SelectedMyViewModel}" /> When the SelectedMyViewModel changes I'd like to have a animation, so that the current view is faded out and the new view is faded in... Somehow I feel this should be possible via the VisualStateManager - but I can't figure out how! This is a WPF 4.0 project...

• Multi Select Checkbox using ListView

  - by Parsa

  I have a CheckBox in the header of ListView. I write a code to select all Checkboxes in ItemTemplate automatically when the user select the checkBox in the header of ListView. This code is useful, when you bind your ListView in DataPager_PreRender. protected void DataPager1_PreRender(object sender, EventArgs e) { //get the user id of the current user Guid userGuid = (Guid)Membership.GetUser().ProviderUserKey; ListView1.DataSource = MyClass.MyStaticMethod(userGuid.ToString()); ListView1.DataBind(); } protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e) { //Find the checkBox in each Row CheckBox checkBoxRow = e.Item.FindControl("CheckBoxRow") as CheckBox; //Assign the value of checkBoxHeader to the checkBoxRow checkBoxRow.Checked = CheckBoxHeader.Checked; } protected void ListView1_PagePropertiesChanged(object sender, EventArgs e) { // assign false value to the CheckBoxHeader when user click on the DataPager // so if checkboxheader is true in the page 1, when user select Page 2,this check box will be false // therefore all checkbox rows will be false in the new page. if (CheckBoxHeader.Checked == true) CheckBoxHeader.Checked = false; }

• how to read a User uploaded file, without saving it to the database

  - by GoodGets

  I'd like to be able to read an XML file uploaded by the user (less than 100kb), but not have to first save that file to the database. I don't need that file past the current action (its contents get parsed and added to the database; however, parsing the file is not the problem). Since local files can be read with: File.read("export.opml") I thought about just creating a file_field for :uploaded_file, then trying to read it with File.read(params[:uploaded_file]) but all that does is throw a TypeError (can't convert HashWithIndifferentAccess into String). I really have tried a lot of various things (including reading from the /tmp directory as well), but could get none of them to work. I hope the brevity of my question doesn't mask the effort I've given to try to solve this on my own, but I didn't want to pollute this question with a hundred ways of how NOT to get it done. Big thanks to anyone who chimes in.

• Trying to speed up a SQLITE UNION QUERY

  - by user142683

  I have the below SQLITE code SELECT x.t, CASE WHEN S.Status='A' AND M.Nomorebets=0 THEN S.PriceText ELSE '-' END AS Show_Price FROM sb_Market M LEFT OUTER JOIN (select 2010 t union select 2020 t union select 2030 t union select 2040 t union select 2050 t union select 2060 t union select 2070 t ) as x LEFT OUTER JOIN sb_Selection S ON S.MeetingId=M.MeetingId AND S.EventId=M.EventId AND S.MarketId=M.MarketId AND x.t=S.team WHERE M.meetingid=8051 AND M.eventid=3 AND M.Name='Correct Score' With the current interface restrictions, I have to use the above code to ensure that if one selection is missing, that a '-' appears. Some feed would be something like the following SelectionId Name Team Status PriceText =================================== 1 Barney 2010 A 10 2 Jim 2020 A 5 3 Matt 2030 A 6 4 John 2040 A 8 5 Paul 2050 A 15/2 6 Frank 2060 S 10/11 7 Tom 2070 A 15 Is using the above SQL code the quickest & efficient?? Please advise of anything that could help. Messages with updates would be preferable.

• Determine fonts used in postscript (.ps) file

  - by Bernard Vander Beken

  Given a postscript file that has the following header %!PS-Adobe-3.0 I would like to list all fonts used in the file. The output does not have to be perfect, but I need to make sure I get all references to any font being used. I am aware there are different types of fonts, and that a font may or may not be embedded in the postscript file. My current best idea is to grep/search for the word Font case insensitively and go from there. Will this get me all the font references? Any better way to achieve this? I tend to use .NET/C# for development purposes, but any solution is appreciated. Thanks, Bernard

• Transferring a flat file database to a MySQL database

  - by Jon

  I have a flat file database (yeah gross I know - the worst part is that it's 1.4GB), and I'm in the process of moving it to a MySQL database. The problem is that I'm not sure how to go about doing this - and I've checked through every related question on here but none relate to what I want to do, nor how my database is currently setup. My current flat file database is setup to where a normal MySQL row is its own file, and a MySQL table would be the directory. So for example if you have a user named Jon, there would be a file for the user in a directory named /members/. Within that file would be various information for the user including the users id, rank etc - all separated by tabs, all on separate lines (userid\t4). So here's an example user file: userid 4 notes staff notes: bla bla staff2 notes: bla bla bla username Example So how can I convert the above into their own rows and fields in MySQL? And if possible, could I do thousands of these files at once? Thanks.

• How does NHibernate handle cascade="all-delete-orphan"?

  - by Johannes Rudolph

  I've been digging around the NHibernate sources a little, trying to understand how NHibernate implements removing child elements from a collection. I think I've already found the answer, but I'd ideally like this to be confirmed by someone familiar with the matter. So far I've found AbstractPersistentCollection (base class for all collection proxies) has a static helper method called GetOrphans to find orphans by comparing the current collection with a snapshot. The existence of this method suggests NHibernate tries to find all oprhaned elements and then deletes them by key. Is this correct, in terms of the generated SQL?

• Question about function returning array data

  - by Doug

  var grossBrackets = new Array( '300', '400', '500', '600', '700', '800', '900', '1000' ); function bracketSort( itemToSort ) { for( index = 0 ; index < grossBrackets.length ; index++ ) { if ( itemToSort < grossBrackets[index] ) { bracketData[index]++; } else if ( itemToSort > grossBrackets[7] ) { grossBrackets[7]++; } } return bracketData; } This is my current code, and I basically want to sort the data into their proper brackets. My source code is really long, but when I input these numbers into the function: 200.18 200.27 200.36 200.45 200.54 bracketData prints 5,5,5,5,5,5,5,5 or is there a better way to do this? Brackets: <300, <400, <500, <600, <700, <800, <900, <1000, greater than 1000

• if_attribute on declarative authorization. STUCK FOR DAYS!!!

  - by Victor Martins

  I can't seem to find a solution for this problem :s I have a many to many relationship like this: A user has_many organizations through affiliations and vice versa. I'm using declarative organizations and I only want a user to edit a particular organization if he is affiliated and the affiliationtype attribute of affiliation is a particular value. So affiliations has 3 columns , user_id, organization_id and affiliationtype_id I can do: o = Organization.find(:first) o.affiliatons[0].user and get the user now I wish to do this: has_permission_on [:organizations], :to => :edit do if_attribute (...) end That if_attribute should see if the current user is the organization.affiliation[?].user and if the organization.affiliation[?].affiliationtype_id = "3" I hope this is syntax issue ... I really need to get this working. Thanks in advance.
