How to use query strings in framesets with asp.net mvc 5 routing

The problem – I was working on a project that required frames – and I was trying to pass a querystring value to the frameset, as in /FramePage/?page=/SomePageOffSite.aspx – my first thought was to just pass the url of one of the frames to the frameset page as a string.  I made the model for the view a string and attempted to pass it via the usual way in the controller, i.e.

return View(“MyFramedInPage.aspx”);

My thought was that I could just use the Model property as the url, as in

frame src=”@Model” name=”main” noresize scrolling=”auto” marginheight=”0″ marginwidth=”0″

However, whenever I did that MVC would try to find a view with the url of the string (in this case SomePageOffSite.aspx – which did not exist) I was passing in the model.  I eventually figured it out – there is a feature I never use on return View – to wit – you can redirect it to another view simply by passing in the view name (I always used the redirect option) – therefore you can’t ever use a model as a string.  Lesson learned.

How to web deploy to a virtual directory or web application in IIS and Visual Studio 2013

For whatever reason you cannot directly deploy (using Visual Studio WebDeploy) to a virtual directory in IIS.  This threw me for a bit until I created both the virtual directory, a separate website, and pointed them both to the same directory.  Then you just deploy to the otherwise unused website, and your web application shows up in your virtual directory

How to fix problems with 404 errors and ScriptResource.axd

I recently had this problem when working with an older site – I fixed it by changing the AppPool Managed Pipeline mode to “Classic”.

Why that worked I had no idea, but work it did!

How to fix problems with Visual Studio 2013 Web Deploy

Recently I began having problems with the Visual Studio Web Deploy feature – I did some googling and found that restarting the “Web Deploy Agent Service” fixes everything – I’m not sure why the service would lock up after a boot but that did fix it.

How to fix problems with small fonts when using the rotativa nuget package

Does the actual html look fine but the text on the printed pdf look way, way too small when you actually print the thing?

  1. In the MVC Controller – add in

    CustomSwitches = “–disable-smart-shrinking”,

  2. Check for long strings of unbroken text, in my case it was a fake underline of underscores (______) which was causing problems.

Blogged about largely in case I ever need to remember it later.

ASP.net MVC remote validation does not check for empty strings

This is a lesson I learn too frequently – asp.net mvc remote validation does not validate when the textbox (or whatever) is empty – it will not check empty strings and the event simply won’t fire.  Why it does this I don’t know but it does not.  I spent an annoying amount of time relearning that recently.  I guess Microsoft wants you to use the required validation fields first, but I run into many situations where the object is not required per se, but is required if some other data is entered.

 

What is the solution?  I’ve had great luck using MVC FoolProof Validation – available here.

Linq projection with the extension method syntax

I’ve looked this up an embarrassing number of times – here is how you do linq projection with the extension method syntax

List<TypeClassification> typeClassifications = ctx.Classes.Select(e => new TypeClassification() {Name = e.Name, TypeClassificationID = e.ClassificationID}).ToList();

Hopefully I shall remember.  I’m not sure why I can’t remember the exact syntax.

A non definitive list of 64 html escape characters for currency

'Currencies on White Background' photo (c) 2011, Images Money - license: http://creativecommons.org/licenses/by/2.0/I recently had to integrate html escape characters for currency symbols on a project, and much to my surprise I could not find any good definitive list html escape characters for currency codes. These are also known as escape characters, character entities or extended characters.  I had to find them all more or less one by one.  Here is what I came up with. For some reason WordPress is not letting me post the escape characters as escape characters, so I have attached a simple text file containing a list of 64 html escape characters for currency symbols. Hopefully this will save someone else 45 minutes.

Here is what is in the file – it is in the Name – Abbreviation – Symbol format.

Five things should should know about the new asp.net identity membership system

I’m trying my first asp.net mvc 5 project, which more or less forces you to use the new asp.net identity framework for membership. It’s in the using Microsoft.AspNet.Identity namespace.

While a vast improvement over the original asp.net membership – I do not see any massive benefit over the MVC 4 Simple Membership system.  Here are 5 things you need to know about the asp.net identity system before you upgrade

  1. The ID column is stored as a guid, and not an int – One of my favorite things about the simple membership system was being able to use int columns for ID – no more of that
  2. In the default project, all of the membership tables will be stored in Local DB, even if you change the connection string in the web.config
  3. MVC introduces a peculiar (to me at least) way of creating the Database tables for membership in the LocalDB – in the IdentityModel.cs file in the Models folder, you will see the following bit of code

    public class ApplicationDbContext : IdentityDbContextWithCustomUser
    {
    }

    this will create the following tables in the Local DB

    • ASPNetUsers
    • ASPNeRoles
    • ASPNeTokens
    • ASPNetUserClaims
    • ASPNetUserLogins
    • ASPNetUserManagements
    • ASPNetUserRoles
    • ASPNetUserSecrets

    if you are running a separate database you will find it quite confusing to get the membership and the other data in the same context (the error message are rather opaque.  To fix the matter, add in the following code in your regular data context class and comment out the ApplicationDbContext : IdentityDbContextWithCustomUser in IdentityModel.cs

    public DbSet ApplicationUsers { get; set; }
    public DbSet Roles { get; set; }
    public DbSet Tokens { get; set; }
    public DbSet UserClaims { get; set; }
    public DbSet UserLogins { get; set; }
    public DbSet UserManagements { get; set; }
    public DbSet UserRoles { get; set; }
    public DbSet UserSecrets { get; set; }

    and everything will both be in the same database and the same data context.

  4. The quick and easy way of getting the User ID (comparable to WebSecurity.CurrentUserID is User.Identity.GetUserID() – that will return the guid of the user.
  5. It is pleasantly integrated with entity framework code first, and will probably be a positive feature over time.

How to fix 502 Errors in WordPress on Windows Azure Websites

For the past month I’ve been getting the following error

502 – Web server received an invalid response while acting as a gateway or proxy server.There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.

I searched the internet – all to no avail – I tried Stack Overflow – no luck.

However, when I tried on the Azure Forums, they suggested turning on Failed Request tracing – which I did.

And while the error logs did not reveal any helpful error information, like “Setting A is set to true when it should be set to false for this to work” it did list quite a few entries for Glimpse – which I was using for my main website (the blog is in a subdirectory).  On a hunch I turned that off, and presto!  The site is working like a charm.  Why Glimpse when the site is deployed I have no idea, but I’m thrilled to not have the error anymore.
