Does the actual html look fine but the text on the printed pdf look way, way too small when you actually print the thing?
CustomSwitches = “–disable-smart-shrinking”,
Blogged about largely in case I ever need to remember it later.
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.
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.
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.

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
public class ApplicationDbContext : IdentityDbContextWithCustomUser
{
}
this will create the following tables in the Local DB
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.
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.
The Problem
I recently came across the conundrum of files not being availble for download after I uploaded them to Windows Azure Storage.
The Cause
Usually the problem is an incorrect mime type, but since Azure does not have mime types I had to do some more digging.
The Solution
It turns out there is a property called “ContentType” that must be set on the Azure Storage Blob programatically – here is an example
CloudBlockBlob blockBlob = container.GetBlockBlobReference(filename);
if (GetFileExtension(filename).ToUpper() == “.SWF”)
{
blockBlob.Properties.ContentType = “application/x-shockwave-flash”;
}
else if (GetFileExtension(filename).ToUpper() == “.MP4”)
{
blockBlob.Properties.ContentType = “video/mp4”;
}
blockBlob.SetProperties();
Once I did that everything worked as intended.
For some reason, most likely because you never do it more than once a year, adding ssl certificates to a server is poorly documented and unnecessarily complicated. Here are some things I learned recently about adding ssl certs on Windows Azure Websites.
I recently added a cert to this site, https://digitaltoolfactory.net which is hosted on Windows Azure Websites. It looks simple enough, just upload a file, sure it’s a .pfx file, but those are avilable aren’t they?
Off I go to NameCheap.com, plunk down my $10 and get a GeoTrust Rapid SSL Certificate. Then you have to generate a CSR – from there just go to your IIS manager and
That’s it!
There are a few caveats.
The big one is that if you have any errors in this process Azure will not tell you – instead all you will get is the big scary “This site claims to be DigitalToolFactory.net, but the actual certificate is for *.WindowsAzureWebsites.net”.
The other caveat is that Microsoft is charging $9.00 per month to host a site site with Secure Socket Layer bindings, which is ridiculous. By my estimation it costs more to host the cert than to host the actual site, which makes it unique in all web hosting. Why they do this I don’t know. I’m glad to have the option, but the amount seems ridiculous – hopefully that fee will drop soon.
So the Gods of Google have gone and changed their basic Google Analytics code to something that works slightly better, and now your outbound link tracking code doesn’t work.
Here is how you fix that – first make sure you have the most recent (as of July 2013 Google Analytics code, it looks something like this)
<script>
(function (i, s, o, g, r, a, m) {
i[‘GoogleAnalyticsObject’] = r; i[r] = i[r] || function () {
(i[r].q = i[r].q || []).push(arguments)
}, i[r].l = 1 * new Date(); a = s.createElement(o),
m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m)
})(window, document, ‘script’, ‘//www.google-analytics.com/analytics.js’, ‘ga’);ga(‘create’, ‘UA-XXXXXXXX-1’, ‘mydomain.com’);
ga(‘send’, ‘pageview’);var clientId = ”;
ga(function (tracker) {
clientId = tracker.get(‘clientId’);
});
</script>
If it does not look more or less like that, then do not use the code below.
Now make the links you want to track look like this
<a href=”http://www.SomeOtherDomain.com” onClick=”ga(‘send’, ‘event’, ‘Outbound Links’, ‘click’, ‘http://www.SomeOtherDomain.com’)” target=”_blank”>www.SomeOtherDomain.com</a>
Note the onclick event – that is the key thing.
Where can you see the result? They do not show up as page views (like they used to) instead they are treated as “Events”. To see them, go to (in the main Google Analytics screen)
1. Standard View
2. Content
3.Events
4. OverView
5. Event Label
And there you are. Not exactly intuitive, but not bad.
In my was posting a contact form to an outside service, and then redirecting to a page on the same site. I thought, Aha, I will use the handy jquery .post command – it looked something like this.
$.post(“https://www.outsidesite.com/FormSubmit.php”, $(“#myform”).serialize());
window.location.href=’http://www.MySite.com/SomePage/’;
But curiously, half of the time I filled out the form the data did not reach the outside server, and the other half the redirect did not happen.
$.post is an asynchronous operation by definition – and cannot be made synchronous.
Just use the regular jquery .ajax function, and set async to false
$.ajax({type: ‘POST’, url: “https://www.outsidesite.com/FormSubmit.php”, data: $(“#myform”).serialize(),async:false});
window.location.href=’http://www.MySite.com/SomePage/’;
That’s it, now the browser waits until the submission is complete and everything works as expected.
