So you want to be a .net developer? Web, Backend, Middle Tier? You’re asking yourself where do I start?

So occasionally I get asked from friends and friends of friends and friends of friends of friends, I want to be a <insert, programmer, web developer, build websites, etc>.  How do I get started?

This is a loaded question. There so many directions to go and languages to choose from and then there is the college route, certification route or both. Then you have the Unix side of the house, the Microsoft side, now the all popular apple and android sides. Web platform, OS platform or mobile platform. Then you have to figure out where you like to work the most; on the front-end UI, back-end logic or maybe the database layer.

So for this article I’m going to with a bunch of assumptions.

  • You want to build web applications (You can apply this to OS applications, website and mobile later)
  • I’m assuming college doesn’t matter and is not needed (though a Computer Science degree would be awesome)
  • You aren’t doing it for the money (more on this later)
  • You’re following the Microsoft track using .NET (though the same techniques can be applied to other languages and application types, got to start somewhere)


You are not in it for the money:

This is my biggest pet peeve. If you are trying to be a programmer because you think they get paid a lot. Stop right now and go find something else to do.  Do what you like not because it pays a lot. Those type of programmers are the worst I ever meet. You go to work and do your job and try to get all your learning from on the job training. You go home and don’t give a crap about your job or try and don’t try to learn and enhance your skill sets at home.  You drain the life out of all the other programmers at work. I’ve seen this time and time again.

If you want to be a good programmer, or awesome, programming needs to be your hobby. You need to go home after work and continue learning.  You have to have a desire to be on the computer; programming your own projects for fun to learn new techniques after work. At home at night on the weekends. In life you should do what makes you happy and what you enjoy. Not because you think you can make a lot of money. If you don’t enjoy programming, don’t do it. I can go on about this so I’ll stop here.


What to Learn:

  • The Presentation Layer (or what we can the “Front-End” work): This is the visual aspects of your application and interactions. What it looks like how it functions.
    • HTML – Must Learn
    • CSS – You can get away with it if you don’t like front-end work but you should learn the basics
    • Javascript – You can get away with it if you don’t like front-end but you should learn the basics
    • jQuery – This heavenly needed for good interactions on your web application but you could get away with this if you don’t like the front-end. However, you should have a basic understanding.

Training Suggestions: On the web. Start with W3Schools. Great site, simple and straight forward. Soak in all the information you need. Always a good resource.

  1. W3Schools – For each section complete the “Basic” section. HTML, HTML5, CSS, CSS3, HTML DOM, JavasScript, jQuery,
  • The Business or Middle Tier Layer (or what we call the “Back-End”): This is the logic and heart of your application. Taking the information provided in the Presentation Layer and doing something with it. Calculations, data manipulation, saving it to the database etc..
    • .NET C# (or VB.NET but C# is more popular now a days and usually pays more (being that you are doing this even as a hobby, then yes pay is important and a side-benefit.))
    • ASP.NET MVC3 (this is newer then ASP.NET WebForms which is just as popular, but MVC is the future)

Training Suggestions: On the web and study books for certifications. Some people knock certifications, usually the ones that don’t have one. Certifications won’t make you great, only experience will do that. However, Certifications will teach you everything you should know and aspects that others don’t know because they don’t study for the certs. Small things here and there that add up. As well as showing to an employer that you might not have experience but you definitely can program and know the basics if you have your certs. More about certs in an updated post. Old post here.

  1. ASP.NET is a great place to get started. Specifically ASP.NET / MV3 site. Go through Chapters 1 through 12.
  2. C# Station – I’d stay maybe go to chapter 8 or 10.
  • The Database Tier (Also, part of the “Back-End”): This is storing data. Manipulating data. How to retrieve the data and run reports or searches.
    • First learn some SQL basics from W3Schools. Go through all the SQL Basic chapters.
    • Optional: Then you can learn say T-SQL which is Microsoft language of SQL built off of basic SQL. However, you don’t need this yet and learn as you go after W3Schools.

This is enough to get you started. Learn all the basics then figure out where you like to play the most.

  • Advanced Items: Other things you should know.

Getting Out of Memory Exception when you have plenty of Memory/RAM available


This is a great article on why having or adding more memory won’t fix your Out of Memory Exception.   Bottom line.. on a 32bit server you’re site will crash when it hits between 600MB and 800MB.  The amount varies based on what else is going on with the machine.   The solution? Basically, you have to upgrade to a 64bit OS or re-write your application.


Why adding more memory won’t fix your Out of Memory error by Edge

Copied from the article directly, in case it ever goes down.


Here an interesting case. Consider there 2 scenarios:

Both are running the same website, both have the same amount of users connected.

Now imagine this website has a page to upload pictures, just like any regular photo-album website.

For some reason, at some point the users complain that they see an error page indicating out of memory error.

So, you wonder: How come? they are just uploading a photo to my website, and I still have plenty of memory in my server anyway.

Anyhow, you stop thinking about this and go for the easiest, quick and dirty solution: If the system tells me that my computer does not have enough memory then I just need to add more memory. Right?

And guess what? you still will get the error message.

That's a very common mistake. Having a machine with 10GB of memory does not mean you will have 10GB of memory available. I explain.

It does not matter if your computer or server has 512 MB, 1 GB, 2 GB, 4 GB or 8 GB of RAM. If your machine is a 32-bit machine it will only be able to see/manage 4 GB. That's mathematics, that's life, that's the way things are and you can't do nothing about it. A 32-bit machine can not do more than that.

Additional memory may increase your system performance, but it won't increase the memory availability. Sure your computer will use less the hard disk for swapping operations and will be able put more stuff in memory and start some programs faster, but 4GB is the limit; after this point the memory management module will start doing disk swap and to use the famous page file.

And here comes more bad news: Your Windows system on a 32-bit machine requires 2 GB allocated only for it.

So, if you have 4 GB installed, effectively you will have 2 GB only for applications; your windows will be using alone 2 GB.

So, what does out of memory means?

Well, according to some people at Microsoft, this limit for an average configuration is reached between 600 MB and 800 MB of utilization. That 800 number is NOT A RULE, is a baseline. Generally speaking the largest majority of configurations with website, .NET and SQL Server database might have a problem around this point. Of course, this can vary from system to a matter of fact a system can be out of memory at just 600 MB.

Yes, it does sounds crazy. You look so happy now that you just bought a 4GB RAM notebook and your computer is breaking with just 800MB, hun?

Here is another point for you. Have you ever seen someone bragging that he/she bought a 10-megapixel camera and now he/she believes their pictures are going to be better because of this?

Well, guess what? Just like the number of megapixels in a camera box does not have much to do with picture quality, RAM memory does not have much to do with hard disk space.

That's a common mistake: People buy RAM as if they were buying a hard disk.

RAM usage needs to me continuous, unlike hard disk. A simple 5MB Microsoft Word document when saved in a hard disk can be split up in hundreds of pieces; When you open this file in memory, the RAM requires those 5MB to be allocated continuously.

Can you see now the reason for the 'out of memory' message?

Yes, it really means 'there is not enough continuous memory to place that file in memory'. Your system might have 2GB of RAM but unfortunately it might be too busy with stuff running and there is no enough continuous memory to put the picture you are uploading.

Yeah, you can not do much but you can buy a 64-bit machine then when you add more memory you can really use it more efficiently. And yes, we have Microsoft Windows systems for 64-bit machines.

If you do not want to buy a new system of upgrade you current server to a better version then you should think other solutions in the business process, such as to avoid users upload pictures with more than 1 MB in size to be uploaded.

Response.Redirect Thread Was Being Aborted. Properly Handle this Exception and not with a Try/Catch.


Due to Response.End calls Thread.Abort.

To avoid this error you can catch for it like most people do it.

Or do it the “right” way.

Don’t call Response.End by using the overload.  Use HttpApplication.CompleteRequest() instead.

Response.Redirect(stringURL, False)

Unfortunately, since you’re not aborting the thread the postback finishes and the html gets sent to the client.

Found a great post on the topic here by John S. Reid, where he goes into details on the solution.  For now, here’s the final solution. I would suggest a base page. But this is what you would have on your actual page.


Private blnPageIsTerminating As Boolean = False

Protected Sub SomePageEventOrOtherMethodThatYouAreRedirectingFrom()
    Response.Redirect(UrlDocumentLink(oCurrDocument.DocumentMasterID), False)
    blnPageIsTerminating = True
End Sub

Protected Overrides Sub RaisePostBackEvent(ByVal sourceControl _
           As IPostBackEventHandler, ByVal eventArgument As String)
    If blnPageIsTerminating = False Then
        MyBase.RaisePostBackEvent(sourceControl, eventArgument)
    End If
End Sub

Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)
    If blnPageIsTerminating = False Then
    End If
End Sub

Disabling ASP.NET Validators via Client Side Javascript

I had the need to disable my expression validator when some other client side events fired a post back.


Here’s the snippet if you need it.

function specialClientSideToDo()
  var reValidator= document.getElementById('<%=reValidator.ClientID%>');
  ValidatorEnablereValidator, false); 


Later I re-enable after I’m done doing whatever I had to do.

Control Your Windows Service from a Asp.NET Web App, Start, Stop, Run A Method


Maybe you find the need to; or you think of the possibilities of controlling a Windows Service from a Web App might be useful.  For me I like the idea of writing a Windows Service that does some server function but can be controlled or called by a user. This is a more detailed post on code examples from the previous post with some other considerations.

Examples Reasons?:

  1. Maybe a Administrator needs to start and stop services but doesn’t have access to the server by normal methods.
  2. A user that calls a Windows Service that performs some type of Emailing functionality such as a notifying users when they have a new Task.  Maybe this table is populated by many means. Win service would check the database every 30min and send off emails.  In your web app, your users are special, so every time they assign a task, you fire off the windows service right there and then. Or maybe sometimes you have the need to fire off a manual send and have written redundant code to do it.
  3. Windows service control center for developers? Or Support users?


Anyway, the process is quite easy.


Windows Service code, somewhere have a method like this…

Code Snippet
  1. Protected Overrides Sub OnCustomCommand(ByVal command As Integer)
  2.     MyBase.OnCustomCommand(command)
  3.     Select Case command
  4.         Case 130
  5.             'Call one of your other methods from here
  6.         Case 150
  7.             'Call some other method or command
  8.         Case Else
  9.             'Do Nothing
  10.     End Select
  11. End Sub

You can only call one CustomCommand, so you send in Command Integers and from there decided what you want to do.


In your ASP.Net app on a button click event..

Code Snippet
  1. Using sc As System.ServiceProcess.ServiceController = New System.ServiceProcess.ServiceController()
  2.     sc.MachineName = "Mastro-PC"
  3.     sc.ServiceName = "ComplyTrackMainTimer"
  4.     sc.ExecuteCommand(130)
  5.     'sc.Stop()
  6.     'sc.Start()
  7. End Using

This will work on a on a button click event. You have to set the MachineName and the ServiceName. You can also Stop() and Start() the Service or look up the Status.

You can get the MachineName of the server by opening a command prompt from the server and typing in “HostName”


You can get the ServiceName by opening up the server and looking at the name in Services. Don’t use the Display Name use the Service Name.


I have a previous post on this with more detailed information on valid Command Integers and Security.

Silverlight Timeout Issues from WCF… exceeded the allotted timeout.


So you’re getting error message…

The HTTP request to <URL To WCF Service> has exceeded the allotted timeout. The time allotted to this operation may have been a portion of a longer timeout.


Three places to set time values to fix this issue…


1) Web.Config

<httpRuntime executionTimeout="600" />

(this is seconds, so here it’s 10min).   More info on httpRuntime here.

2) On your Web.Config Binding Elements

<binding name="customBinding123" 
closeTimeout="00:10:00" />

3) On your ServerReferences.ClientConfig binding elements within the system.serviceModel

<binding name="CustomBinding" 
closeTimeout="00:10:00" />

On Authentication Timeout - Save Web Form Contents

I was working on a project recently where I had to figure out how to persist user data in a web form after their Forms Authentication session as expired.

So I was thinking of ways to do this as I searched the know all Google. Walla!  Someone's already had to do this, why invent the wheel.  Found a post by Peter Ravnholt, on the MSDN site. 

He Implements the HttpModule and handles saving the form state on FormAuthentication events. Really neat idea.  I tried is code, now keep in mind I'm doing this for Visual Basic, so I manually converted it all, but I couldn't get it work. Maybe I was converting something wrong.  I was getting "The state information is invalid for this page and might be corrupted."

Well RichardDeeming in the discussions for this post had an updated version that worked a little better then the original.  Thanks to his code, I converted it to VB.Net and walla!  My pages now handle web content.

I'll post the converted VB version below. 

Thanks Richard and Peter if you ever find your names on here via Google :p

This is my VB version o the FormSaverHttpModule with Richard's changes.  I've modified it a bit since but this works.

IIS7 Windows7/Server2008 ApplicationPoolIdentity Security Change from Network Service


Yeah this one got me..

The change microsoft made to have AppPool now run as “ApplicationPoolIdentity” instead of Network service.

So if you normally give Network Service rights needed to your webapp, you now have to stop doing that and change it to

IIS AppPool\DefaultAppPool



End of that.





  1. Open Windows Explorer
  2. Select a file or directory.
  3. Right click the file and select "Properties"
  4. Select the "Security" tab
  5. Click the "Edit" and then "Add" button
  6. Click the "Locations" button and make sure you select your machine.
  7. Enter "IIS AppPool\DefaultAppPool" in the "Enter the object names to select:" text box.
  8. Click the "Check Names" button and click "OK".

By doing this the file or directory you selected will now also allow the "DefaultAppPool" identity access.

Optimizing Pages that use Telerik Controls. Mainly RadGrid


I was watching a webcast on Telerik TV, it’s called Optimizing RadGrid for ASP.NET Ajax.  There is a lot of useful information there. I summarized a bunch of it.

On my test page I…

  • Added Browserfile...
    • Compressing ViewState for RadTelerik controls  (Dropped viewstate considerably from sample page, 50,776 bytes to 5,428 bytes)
  • Added RadCompression for AJAX Calls to drop traffic size on ajax post-backs (Not handled by IIS compression)
  • Reduce Request using StyleManager and RadScriptManager
    • Added RadStyleSheetManager to MasterPage (Combines all CSS sheets into one download to limit requests)
    • Switched to RadScriptManager on Masterpage instead of ScriptManage
      • Request dropped from 71 to 47


Summarized Tips

  • Bind Grid Data on PreInit event, this will keep data from going to the ViewState and cut down on page size
  • If the Grid is ReadOnly and no editing takes place, then turn off viewstate for the Grid. EnableViewState="False"
    • Features that will NOT work when viewstate is off
      • Custom Edit Forms (User Control or Form Template)
      • Filtering
      • Grouping
      • Using Cached Data and Paging Together
    • Features that WILL work when view state is off
      • Indexes of Selected Items
      • Indexes of Edited Items
      • Group-by Expressions and Settings (but not the expanded state of grouped items)
      • Sort Expressions
      • Style Properties (But not if applied to a single cell or row in ItemDataBound event)
      • Column Order and other column properties
      • All settings concerning hierarchy structure (but not the expanded state of the items)
  • Optimized Column Editors on Grid
    • Used Shared Data Picker for Date columns in your grid
      • This requires a hidden data picker on page, and template column with textbox that uses js to talk to the datepicker with client-api (See Example Here)
    • Use Template column for comboxes and use Load-On-Demand
  • Ajaxify the Grid
    • Compresses Ajax calls which IIS misses, use RadCompression to drop traffic size
    • Use StyleManager and ScriptManager to bundle all css and scripts into one call each to server
  • More Tips Here
  • Other Ways to Optimize
    • Client-side Binding
    • Custom Paging
    • Virtual Scrolling
    • Caching Data server-side
    • Hierarchy Load modes
    • Group load modes
    • Filtering
    • .NET 3.5 + Linq
    • Upgrade from IE6


Other Controls

  • Other Controls
    • Use Shared Data Picker
    • Use RadInputManager if you want Validated or Stylized instead of using the the RadNumeric or RadTextbox controls
    • Use Load-On-Demand RadComboboxes
    • On RadMultiPage set RenderSelectedPageOnly = True
    • Hide Grid's with Visible="False" not with surrounding Div's set to display none.
      • Hiding the Grid itself, it doesn't render or get bound, grid will get data when visible is set to true again.
  • Add App_Browsers folder with a file that has.. (This one is HUGE, dropped my page significantly)
    • Create a file and add
    • <browsers>
          <browser refID="Default">
                  <!--<adapter controlType="System.Web.UI.Page" adapterType="Telerik.Web.UI.RadHiddenFieldPageStateCompression" />-->
                  <adapter controlType="System.Web.UI.Page" adapterType="Telerik.Web.UI.RadSessionPageStateCompression" />
