In Azure as IaaS (Infrastructure as a service) model, dedicated VMs are assigned to you with full control over O/S, updates etc. Generally used for application development, testing and IT operations.

In Azure as PaaS(Platform as a service) model, Azure controls the VM instance and maintains the environment(O/S, updates etc.), while you are just concerned about your application.

re: DiscreteSlider - Adding Functionality with a Simple Control Subclass

Toto's solution works for dragging the slider, but on Windows Phone Mango, clicking on the slider bar to move by SmallValue doesn't work properly, the slider stays where it is but the value changes. To fix this, I changed the comparison line like this:

if (newDiscreteValue!=Value || Value!=oldValue)

This allowed me to drag the slider as well as click to the left or right to change the value.

Additionally, if you want to avoid comparison two floats for inequality:

if (Math.Abs(newDiscreteValue - Value) > 0.000001 || Math.Abs(Value - oldValue) > 0.000001)

I've no idea whether 0.000001 is the "right" value, it just worked for me :)

Confirmed that it behaves the way vienigais describes. It's easy to correct though.

Change the line

if (newDiscreteValue != m_discreteValue)

into

if (newDiscreteValue != Value)

and it behaves correctly..

Just for info:

Regarding issue of Jaybo, Joe, James, and Paul.

I had the same thing and solved it with advice from MarkChamberlain post 1/6/2011 1:19 AM from forums.create.msdn.com/.../436721.aspx

which is "Not use the GestureService and use TouchPanel directly instead (GS is just a wrapper around TP)".

How to use TouchPanel you may find here www.nickharris.net/.../using-touchpanel-for-gestures-in-windows-phone-7

Hi Dave,

Thanks for the post. It really helped in using a better slider in my application.

I have a requirement of placing two sliders in a same row grid.

But I am facing a small problem when i use two sliders in a same row of my "slider grid".

Only the second slider moves, even when i try to move the first slider?

It very strange i am unable to understand how the even of 1st slider goes to second one :(

Can you please help me?

Thanks once again!

Thank you Dave! Great slider. It teached me how to make a usercontrol from another control!

But can you tell one thing?

I have horizontal slider as one of ScrollViewer child. If first touch position while I am scrolling was on a slider, Viewer is not scrolled and value of a slider is changing.

Can I add something like checking of dragging X and Y and react only X > Y for horizontal slider and Y > X for vertical? Otherwise to "pass action" (?) to a parent (for example ScrollViewer).

The class works great, thanks! However, it crashes design view. Add this code to resolve

if (DesignerProperties.GetIsInDesignMode((FrameworkElement)Content))

return;
