Unity Editor freezing After Initial Start

For about three month now I've been working on a little project in unity3d. The project is simple I have a udp socket in c++ and I want to communicate with it in my game. Currently it works great going out to my server. I can see all the requests and the speed is awesome! However here comes the big issue, unity after its first run freezes. Hard nothing is responding and the editor is completely useless until I close it and open it back up. For two weeks I stopped programming because of this, it was a stopping point for me until I figured out what was happening. At first I thought it was the game and after doing some reading messed around with the settings. With my issue it had nothing to do with rending/lighting.
    It just happening to come to me last week after reading an article on threading. It was the last bit of code they gave as an example about proper closing a thread. Which got me thinking about my issue, I think unity is holding on to the upd connection and cause …

Updating to ParticleSystems In Unity3D

This article loosely based on a service I want created and hopefully will soon be published. I just thought it would be beneficial for some to know. Since I like to keep on top of things this is one of the many issue I run into when adapting other people's code. This is a huge jump from 2016 to the 2017 version of unity3d.

Google Service Account with Aspnet MVC Behind A Proxy

Recently I had a fun project to attach google analytics data to an internal site which took longer complete than I thought intial thought but now I could complete in just a day. My biggest issue was finding out the issue was related to the company's proxy. Which I quickly fixed by just added the following snippet at the bottom of this article. For everything else this is just my notes and things I found to help me drill down into the queries for grabbing the data.

This is an article I started to working for the project: rustkickers, which for now I'm putting on hold. What I was trying to do was kill two birds with one stone. If you need a good sitemap to submit to google or to create a "site map" for you users then this would do it. I haven't finished making it but there is where my notes are.

Diving Back into Selenium and Getting Somewhere!

Recently I've gone back to using Selenium and started to really get comfortable using it. One of the problems that I constantly face when using Selenium is not having good example and looking at Selenium as a whole in whether it is worthwhile. My problems only get work when I have to ask me whether to use the Selenium IDE or the server package.  Which is more scalable to do? Which one is better to give to a team QA that non-technical? Some of these questions can be answered on the Selenium site but some of them depend on your work environment and how much time you want to spend on creating a system of some kind to do all that.      What you really want for all project is something that you can automate across popular browsers not just a single one. Plus avoid doing a dry run every time to correct your UI tests. So the IDE which really a plugin is not going to do that for you but even if I gave it to a QA non-technical team I don't think it would be used effectively. Instea…

NPOI Does Not Support CSV

I've been using NPOI for sometime now and was recently asked to create a process to output some data in a csv for better support. I was hoping to bring NPOI in the mix but I had to ask myself does NPOI support CSV/TSV?, simply put no.


Library Version - Reading/Writing
Project Version - Server/Storage Features included.

And... There just doing it my way. Personally speaking I didn't like jumping into FileHelpers, I felt was much more overhead than what I need so I looked at creating a small snippet of code for myself. Unlike with NPOI, I also didn't like from what I could see was examples that needed a model to be passed in. Either way, I will try to post an update when I have finished that piece of the puzzle.

I was working on this idea a few years back and the idea was to make two partial views in an MVC more scalable. I was looking the down road for something that could handle whatever the object was and display it. What I later discovered thanks to a colleague was that I should just do a reflection of the object but I feel the better longer term solution could be found in third link of resources. Rather than spend anymore time on this idea I simply kept the two partial views and wrote this down as I have bigger plans with this strategy in mind for a project.

Setting up QunitJs for MVC Debugging

Using QUnit is important for me on some of my projects that are more front-end driven. So developing, debugging and testing all need to happen in javascript but without being in the final production. One thing I do not want to do is include the QunitJs in my bundles and would serve no purpose because the bundling and minifying does not happen for debugging. Instead what I did was create an extension method and return a bool, like the one shown in the resources.
//Location ../Helpers/IsDebuggingpublic static bool IsDebugging(this HtmlHelper helper) { #if DEBUG return true; #else return false; #endif } //Location ../Views/Shared/_Layout.cshtml//These two files are not apart of any bundled packages.@if(Html.IsReleaseBuild()) { @Scripts.Render("~/Scripts/qunit-1.14.0.js") @Styles.Render("~/Content/qunit-1.14.0.css") }Side Notes

Using Entity Framework and a Storage Procedure with Parameters

So I was stuck sometime ago on a problem I had where I was using my sql store procedure with the Entity Framework. Eventually found what I needed and the purpose of this article is just to write out a small example. I've come up with multiple ways to achieve the same thing now but this is the most basic form of it.

Orchard: Filter out Content Types From Restricted Users.

I want to be very clear I did not write this code but it was provided to me and I was given permission by a colleague of mine to submit it.. To respect his privacy I will not be able to provide his name but on his behalf I did submit the code to help improve the orchard project. To explain it a little bit what the purpose of this code edit, it is to filter out content that is editable but the user does not have the permissions to create them. Normal what Orchard would do is display all creatable content and if a user clicks on a particular content type that is restricted it simply replies to the user that they do not have access to it. However with a lot of CMS projects I have developed it is sometimes better to simply hide what the user can not or should not be able to do. Less questions come up and even less problems are seen from the user's perspective. This is what I consider to be a best practice to provide the user with a good experience.

Unauthorized Ajax Handler for MVC

     I need respond to users that they are unauthorized, and I need it to not return a redirect to them from a ajax call which MVC does by default. A even better solution would be that I also do not force users to refresh page they are currently on and instead give them the ability to re-login via ajax on that current screen. This would allow users to save any  information they are currently working on. I should warn the user that it they are no longer logged in and if possible prompt them and within that same prompt allow them a way to login back in all without refreshing or a redirect. For now I'm going to just focus on the first problem which is suppressing Asp.Net's default behavior with unauthorized calls and do this just for Ajax calls.

Solution - Thanks to Joe Harrison for missing pieces!

At the Start of My C# Research

This article is a list of resources that I used way back at the start of my career with C#. Since there are a lot of C# tutorials already out I just wanted to write out some of my experiences and topics that I was curious to learn when starting out. The main reason why I wanted to used C# for programming was for MVC applications and toward the second year I discovered XNA.
Getting Ready at the Start!
    If you're a Java Developer the using Statement is much like a import and include in C++. Having experience with both languages doesn't hurt and speaking from my own experiences with both languages, C# is probably the easiest compared to all of them. And for multiple reasons, but mostly because of Visual Studio's Intellisense in my opinion.

MVC Excel Email Attachment with NPOI

The First Question I had after successfully creating a Excel sheet was how do I create an attachment from a stream? A second to be more specific was how do I add an attachment to an email using System.Net.Mail? Ultimately I wanted to have the Excel Exports in C# using NPOI but I started small and thankfully others had already asked and answered these questions. After which was just a matter of knowing What the correct content-type for excel files was?
First Attempt
MailMessage mail = new MailMessage(); HSSFWorkbook workbook = CreateExcel(OrderId); MemoryStream ms = new MemoryStream(workbook.GetBytes()); mail.Attachments.Add(new Attachment(ms, "example.xls", "application/")); _emailService.SendEmail("", "Email test", "Testing 123"); Changed it to.. MemoryStream ms = new MemoryStream(); workbook.Write(ms); This was based on the QA "NPOI - Sending workbook as ema…

MVC Data Exported to Excel with NPOI

This is an article for just writing an Excel file using NPOI and I want the quickest and easiest way to export a excel file from MVC. To keep everything in work fluid motion I will keep the user on the same page and do a forced download within that page. This is a setup that I have seen in multiple times and I think works great in today's modern website designs.

C# vs. Javascript Foreach

This article is about a certain style of writing in Javascript that I like use when iterating through an array combined with a foreach which looks something like the following...
var someArray = ["1", "2", "3"]; $.foreach(someArray, function(key, value){ console.log(key + " , " + value); });      Ultimately when I tried to take this same concept over to C# the style did not convert over in the exact same way. I found that the temp variable being used to iterate with did not have any values that tracked where it was in place of the iteration. I found myself asking a similar question in how do you get the index of the current iteration of a foreach loop? To see what I tried you can look at another person's problem where I had attempted in the same manner. Attempting to use the "current" value in the GetEnumerator() sadly does not work.

     To summarize the answer for this problem the "foreach" uses th…

A Static DropDownList for ASP.Net MVC

When creating a static dropdowns list in MVC, I have a two approaches that I like to commonly use. I know there are many ways to achieve this UI structure and I don't consider either one of the following approaches to be the final solution. However for awhile now I have been using these two approaches and I think they are much simpler and easier to maintain compared to other ways that I have seen. Rather than writing out the HTML select tag and all the options I take advantage of the Html Helper Dropdownlist. I avoid model bind since it is static and I don't want create the list outside of the view. I think this would only create more work to maintain and confusion for other coders if they new to my applications.  I did not come up with either solution completely on my own and I actually forget where I saw them since it did take a while to find these approach in my research.What's important to take away in this article is that if you look carefully you will se…
