BLAZOR SERVER 403 FORBIDDEN ERRORS

Tuesday, July 4, 2023

--------------------------------------------------------------------------------

PROBLEM

Kept receiving 403 forbidden errors when moving code to production.

I believe the issue was related to copying the .NET 7 code into a location where
.NET 6 code lived. I tried the code below which was UNSUCCESSFUL.

GIT - .GITIGNORE ISSUES

Wednesday, December 11, 2019

--------------------------------------------------------------------------------

A common issue you may have when using Git and different projects, especially
new projects is accidentally committing files you don't want to.

As you make changes, you may run into an issue where gitignore doesn't seem to
ignore folders or files that are clearly marked to be excluded from the
repository.

Below are steps to fix your repository.

AZURE HOSTING - SETUP

Sunday, May 19, 2019

--------------------------------------------------------------------------------

If you have a Visual Studio Professional subscription you are eligible to get a
$50 credit each month to use for any Azure services.

To get started you'll need to create what Azure calls resources.

CREATE A VIRTUAL MACHINE

Select your Subscription and your Resource group (Create New if there is none).
Then select your region and the image (Windows Server 2016 Datacenter). For
image size, I'm using Standard B2ms (2 vcpus, 8 GiB memory) which due to the 8
gigs of RAM makes working in RDP less painful.

GIT - TEAM ENVIRONMENT

Tuesday, May 14, 2019

--------------------------------------------------------------------------------

Git is probably the most popular source control tool out there right now. It can
be confusing at first even if you are experienced with other source code
repositories (TFS, SVN, etc.) After you learn the basics and get a strong
foundation, you usually realize how helpful it is and it starts to make sense.

MVC 2 ROUTING

Saturday, April 13, 2013

--------------------------------------------------------------------------------

ROUTING

I was having problems with a URL and my controller recognizing it and found out
that where you add the route within global.aspx.cs is very important.

// blog/add
routes.MapRoute(
    "BlogAdd",
    "blog/add",
    new { controller = "BlogAdd", action = "Index", id = UrlParameter.Optional }
);

// blog
routes.MapRoute(
    "Blog",
    "blog/{id}",
    new { controller = "Blog", action = "Index", id = "" }
);

LOADING TILE MAPS ON WINDOWS PHONE

Friday, September 28, 2012

--------------------------------------------------------------------------------

The problem I ran into when trying to create a Tile Mapping engine was reading
data on Windows Phone. Windows Phone will not allow the below namespace so I had
to go another route.

using System.Runtime.Serialization.Formatters.Binary;

Windows Phone has a class called TileContainer which allows access to the
Phone's Content area.

JQUERY TEMPLATES

Thursday, September 13, 2012

--------------------------------------------------------------------------------

Using JQuery Templates to search Blogs.

Place the Jquery Templates script on the layout page or on the page using the
template:

jQuery.tmpl.min.js

The JavaScript file contains the code below:

RAZOR ENGINE

Monday, August 13, 2012

--------------------------------------------------------------------------------

My Blog model has categories associated with it (MVC3, Razor, etc.), so in order
to edit which category goes with each blog I used the code below. The code below
loops through each category so that they are available.

CheckCategory is a function that loops through all of the currently selected
categories and returns true so that I can mark a category as being selected.

TWITTER FEED - JAVASCRIPT AND XML

Thursday, March 22, 2012

--------------------------------------------------------------------------------

The LoadTweets() function pulls in a certain amount of tweets from a Twitter
account. This function parses the tweet and updates links so that they are
clickable.

The URL below will send an XML result. Change the publictimeline to a valid
Twitter account and indicate the amount of tweets you need to receive.

LINQ TO SQL LIKE

Friday, March 16, 2012

--------------------------------------------------------------------------------

When searching and the need arises for LIKE '%query%' using Linq to SQL, use
below:

[Route("search")]
[HttpPost]
public IActionResult Search(string search)
{
		var posts = _db.Posts
				.Where(x => x.Body.Contains(search))
				.Where(x => x.Title.Contains(search)).ToArray();

		ViewBag.SearchCriteria = search;
		ViewBag.TagView = new TagView(_db);

		return View(posts);
}

PARTIAL VIEWS

Tuesday, October 18, 2011

--------------------------------------------------------------------------------

Add a View to the project. Check the "Create a partial view (.asxc)' check box,
select "Create a strongly-typed view" if using a model with page and select the
"View data class" if creating a strongly-type view.

%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl>" %>

<% foreach (var blog in Model) } %>

ASP.NET TIMEOUT PROBLEMS

Friday, January 28, 2011

--------------------------------------------------------------------------------

"Connection to database has timed out." This error will occur if there is a lot
of processing being used by a SqlDataReader on a web page. My quick resolution
was to increase the CommandTimeout on the SqlCommand object.

SqlCommand objCmd = new SqlCommand(spProcedure, objCon);
objCmd.CommandTimeout = 120;

DIFFERENT APPLICATION POOLS WITHIN AN APPLICATION

Friday, January 28, 2011

--------------------------------------------------------------------------------

PROBLEM:

You have an ASP.NET 4.0 website running. Within that folder structure you would
like to include a separate application that is built on ASP.NET 2.0. The
solution is in the web.config file.

SQL SPLIT FUNCTION

Tuesday, January 18, 2011

--------------------------------------------------------------------------------

PROBLEM:

Had an application that contained a field in SQL Server which stored all of it's
keywords as a comma delimited string. This presented a problem when doing
searches by keywords and was hard to maintain. So, I wanted to move each keyword
in this field into a keyword table instead of listing them all seperated by
commas.

CS0016 COULD NOT WRITE TO OUTPUT FILE

Wednesday, December 22, 2010

--------------------------------------------------------------------------------

Just finished creating my new ASP.NET 4 application and after I copy over the
files from my development server to production, I get the dreaded "CS0016: Could
not write to output file" error!

This is usually an indication that their is a permission problem of some sort.
After searching for a while on google, I decided to do some of my own tests.
From looking on the web, people were having success adding NETWORK SERVICE and
the IIS_IUSRS accounts to the folder below:

%SYSTEMROOT%\TEMP1 = TEMP
%SYSTEMROOT%\TEMP1 = TMP
