Music broadcast has come a long way from age old radio stations to digitally downloadable to online streamed contents. Online radio stations have survived for almost a decade and with decreasing internet tariffs they are fast becoming popular.
Couple of my favourite online radio station are di.fm and sky.fm which have some awesome channels. These stations stream content in various formats such as MP3, AAC etc. The only problem with them is, you have to rely on their website to change the channels if used from desktop based systems.
Coming back to the problem of relying on website to change channels, I was planning to develop my own Windows desktop based client. While doing research related to this came across a project at DI’s forums called as “DI Radio Player”
It has some good features and few of my favourites are listed below.
This radio player is based on .NET 2.0.
You can follow the following link to discuss and download the player.

Both these Digital Imported & Sky FM channels have awesome mobile clients (DI, Sky) in almost all mobile OS categories + For the upcoming Window 8 Pro OS based tablets, this app will be a good option. Especially with Intel Clover Trail
When a SharePoint 2013 needs to be deployed in a server which doesn’t have internet access, and SharePoint requires prerequisite to be installed, we can do couple of things.
Downloading prerequisites
We can download prerequisites using Powershell. Please use the following script.
Import-Module BitsTransfer
## Prompt for the destination path
$DestPath = Read-Host -Prompt "- Enter the destination path for downloaded files"
## Check that the path entered is valid
If (Test-Path "$DestPath" -Verbose)
{
## If destination path is valid, create folder if it doesn't already exist
$DestFolder = "$DestPath\PrerequisiteInstallerFiles"
New-Item -ItemType Directory $DestFolder -ErrorAction SilentlyContinue
}
Else
{
Write-Warning " - Destination path appears to be invalid."
## Pause
Write-Host " - Please check the path, and try running the script again."
Write-Host "- Press any key to exit..."
$null = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
break
}
## We use the hard-coded URL below, so that we can extract the filename (and use it to get destination filename $DestFileName)
## Note: These URLs are subject to change at Microsoft's discretion - check the permalink next to each if you have trouble downloading.
$UrlList = ("http://download.microsoft.com/download/D/0/F/D0F564A3-6734-470B-9772-AC38B3B6D8C2/dotNetFx45_Full_x86_x64.exe", # Microsoft .NET Framework 4.5

ForEach ($Url in $UrlList)
{
## Get the file name based on the portion of the URL after the last slash
$DestFileName = $Url.Split('/')[-1]
Try
{
## Check if destination file already exists
If (!(Test-Path "$DestFolder\$DestFileName"))
{
## Begin download
Start-BitsTransfer -Source $Url -Destination $DestFolder\$DestFileName -DisplayName "Downloading `'$DestFileName`' to $DestFolder" -Priority High -Description "From $Url..." -ErrorVariable err
If ($err) {Throw ""}

Else
{
Write-Host " - File $DestFileName already exists, skipping..."
}
}
Catch
{
Write-Warning " - An error occurred downloading `'$DestFileName`'"
break
}
}
## View the downloaded files in Windows Explorer
Invoke-Item $DestFolder
## Pause
Write-Host "- Downloads completed, press any key to exit..."
$null = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")Once all the prerequisites are downloaded, copy them to server in a particular path and create the following batch file.

I was faced with a micro challenge, of converting a List<int> to List<string>. After struggling for some time, decided to Google and found the the following solution !
List intList = new List();
List stringList = new List();
for (int i = 0; i < 10; i++)
intList.Add(i);
stringList = intList.ConvertAll(delegate(int i) { return i.ToString(); });Source: http://stackoverflow.com/questions/44942/cast-listint-to-liststring-in-net-2-0

When doing certain code operations in SharePoint like getting list of templates will lead to “Access Denied” exceptions. For such instances we can wrap the code within the following lines to execute code with elevated privileges.
SPSecurity.RunWithElevatedPrivileges(delegate()
{
//Code goes here
});We were developing a Server Object Model based functionality in SharePoint involving site creation using template. During development we use to get the following error in quick watch window.
Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.
To solve this issue we added the following code before the actual statement and issue was solved.
SPSecurity.CatchAccessDeniedException = false;
