Unless you have been living under a rock the past few days you already know about the recent release of Windows 8 Consumer Preview and Visual Studio 11 Beta Buy Betnovate Without Prescription, .  Since I know you already downloaded and installed all the shiny new toys, let’s take a quick look at how to get started writing a custom control for the new metro style applications.  There is no better control to start with than the ever popular WatermarkTextBox control.

Setting up the Solution

First start off by creating a new metro style application in Visual Studio 11 beta.  A blank application will work just fine for our purposes.

When your solution loads right click the project and select" “Add New Item”.  When the dialog appears choose the “Template Control” item template.  Of course give it a name of WatermarkTextBox.

You will notice that the Template control is just like a Silverlight or WPF custom control.  It comes with a class file and a corresponding style in the Generic.xaml file.

Writing the Control

Our WatermarkTextBox control is going to derive from the TextBox class that is already provided by Microsoft.

Having said that, we don’t want to reinvent the wheel when it comes to styling the TextBox we are deriving from.  So let’s save some time by dropping a TextBox onto the BlankPage.xaml page.  Now right click the TextBox on the design surface and select “Edit Template –> Edit a Copy”.  This will create the default TextBlock style that we can use in our WatermarkTextBox ControlTemplate.

Now open up the Generic.xaml file and replace this:

With this:

Let’s test what we have so far.  Add an instance of our WatermarkTextBox control to the BlankPage.xaml.

Looks great.  Just like the default Windows TextBox.  Now we need to start adding our Watermark elements to it.  Obviously we need a property for our Watermark.  Your first thought maybe to define it as a type of string, but I want to support any element, not just text, so I will define it as a type of Object.  This will allow me to nest controls inside of the Watermark property instead of being restricted to a simple string.

I also want to define a DataTemplate that will be used to define the ContentTemplate for the Watermark.

Now we need to modify our control template to support our new Watermark property. We will do this by simply adding a ContentPresenter to our Template.

Oh, effects of Betnovate, Is Betnovate safe, and don’t forget the ContentTemplate that will define the default look for our watermark.  This is placed at the top of the Generic.xaml.

And we need to set the default value in a style setter.

As you can see, I placed the ComtentPresenter after the ContentElement and before the DeleteButton elements.  You may have also noticed that I set the visibility to Collapsed.  This is because by default I want the Watermark hidden.  So that means we need to add some code to show the watermark when the text box has no focus and it has no text.  First we need to add some visual states to the VisualStateManager.

Next we need to add some code to handle the GotFocus and LostFocus events of the TextBox.  Start by adding event handlers for the events in the constructor.

Now add the code that does the heavy lifting.

One last thing is to make sure we set the visual state when the template is applied.  So override the OnApplyTemplate method as follows.

That should do it.  Now let check it out in action. Be sure to provide a watermark for our control.

Yes, Betnovate from mexico, Betnovate description, we found a bug

Everything seems to be working perfectly.  Until you actually try to use a watermark that isn’t text.  Try using this as your watermark.

Now let’s see our results.

Hey!  Where is my watermark?  Well there appears to be a bug with a ContentPresenter/ContentControl that will not display content when the ContentTemplate has been set and the Content is anything else except a string.  This just so happens to be the exact same bug that exists in Silverlight.  Interesting I know.  So how do we fix it?  We have to delete the usage of our Watermarktemplate until this gets fixed.

Change:

Now let’s see what happens.

Now that’s much better.  Let’s hope this is just a beta bug.

So here is a hidden performance increasing jewel you might find useful.  We can set the default open mode to be in full XAML view.

First thing you need to do is in Visual Studio go to your Tools ==> Options ==> Text Editor ==> XAML ==> Miscellaneous.  There you will see an option for “Always open documents in full XAML view”.  Check that box.

Now every time you open a XAML file it will open in full XAML view and give you one less thing to gripe about.

Since when is a successful operation a problem?  Now, of course, I am assuming this is intentional and is transmitting information back to Microsoft to tell them that it was successful.  But, I can see how easy it would be for someone to mistaken this for a legitimate error.  Then again, maybe it is.

You know how Visual Studio creates default files in a test project when you create a new one? Those days of immediate file deletion are over, baby!

So, how do I disable resharper to make sure I don’t get any pesky resharper files into my directory structure? By using Visual Studio’s Add-In manager.

1. In Visual Studio go to Tools > Add-in Manager.
2. Uncheck the ReSharper 4 Add-in and then unselect the Startup box so that when you start up VS the next time, the Add-in won’t load.

Not so fast, Gerome! Turns out that when ReSharper installed, it installed in such a way as to make this impossible. The fix is easy.

In your ReSharper Program Files directory, JetBrains\ReSharper\v4.0\Bin, find the Product.VisualStudio.90.AddIn file. Visual Studio needs to be able to modify this file and the installer laid in down read only. Make the file write-able and go back to VS and go through the process again. This time you will be able to turn off startup.

Even after doing this, the ReSharper menu remains in my IDE, which bugs me. All of the functionality is disabled and the context features in the code files are gone, but still…

• Simplified the user experience through cleaner "Add to Source Control" dialogs, drag and drop support to the Source Control Explorer and a much easier to use "Workspace" dialog for working folder mappings.
• Version control now automatically supports non-solution controlled files.
• Various changes to the Source Control Explorer such as a new checkin date/time display column, local path hyperlink support and en editable source location field.

I am not a big fan of installing a beta SP on may dev laptop, but I gotta tell ya, I did it for that feature alone.

Go here:

And get this screen.

Why? Because if you have made some changes to a file while it wasn't checked out, you will not have the option to merge to your local machine. This option will simply overwrite your local code file.

Why does this feature exist? Because oodles of people asked for it because they were used to it in Source Safe, and the team relented.

Repeat: This is a bad idea!

If, however, you are a person who simply must have this turned on in order to feel snug, there is a way to do it without making your entire team experience the hell that will be yours.

In Visual Studio, go to Tools > Options > Source Control > Environment and do this:

I warned you.

We know that the modeling tools in Team System 2008 are, well... there's room for improvement. How valuable is a Logical Data Center Design Model when we can't derive it from a reverse engineering action? There has also been much frustration with the lack of standard UML support in Visual Studio. Guess what?

Rosario proposes that we promote modeling to a first class citizen of the complete Application Lifecycle Management model. Here's my major takeaway: The way modeling is being supported enables visual exploration of your code base in a way that is seamless with the development process. This can honestly change the fundamental code development experience.

Also, I can plan on sun setting all my organizations Sparx licenses. Cool.

• UML 2.1 at the logical layer
• DSLs at the physical layer
• Generate models from existing assets. This is being discussed as "Architectural Discovery" which is a hilarious term in itself.
• The April CTP has the following
• UML Class Diagram
• UML Use Cases Diagram
• UML Sequence Diagram
• UML Component Diagram
• UML Activity Diagram
• Architecture Explorer
• There is a unifying model underlying all of this, the diagrams are simply views upon that model.
• Newer versions will have some of the features we got to see today. These will come in another CTP later this year.
• Layer Diagram
• Seriously cool, this allows to separate concerns of our tiers in a system.
• I can bind my namespaces to logical layers of my application
• Also has some seriously cool visualization tools for looking through your code.
• Using these views, we can see our cohesion and inheritance in physical form.
• How about namespace visualization using a graph model? Dang, this is cool.
• How about a dependency visualization? NDepend better look out because this one isn't half bad.
• AND, all views enable us to click right through to our source code. Neato.
• XMI support (seriously, wow). This means we can export models from other applications like Sparx EA, Altova, and Rational and bring them right into Visual Studio. Oh, and it will pull Visio models as well.
• Round tripping of component models to code
• Peter actually built some sequence diagrams and I gotta say that this UX is going to be MUCH better than Enterprise Architect, which will soon loose it's Market Share. Even use cases look neater.
• Sequence diagrams can be round tripped with classes and even methods. This means we can examine the complexity of our code at a usable level, and do it visually.

What if you could prescribe separation of tiers and limit leaky abstractions?

Nuggets

"Any system should be possible to represent on a white broad in no more than 13 boxes."

"Using model is simply a way of managing complexity."

"There will be a model store capability that means we don't need to keep our models in the same solutions with our code." But you can :)

Because the models are all built on DSLs, there is someone out there who has automated the process of building test cases from activity diagrams. That is hotter than a 2 dollar pistol.

We can attach other files like Word files to your model itself.

What if we could could light up the models in the debugger to see highlighting of current activity in a sequence diagram? Neato.

They are trying to figure out how to include support for generating design patterns like found in EA and Rational. This is fun because you can generate domain specific code with a fundamental implementation in a known design pattern like Forward Controller or something.

I need a bigger monitor. Seriously, boss. I need a bigger monitor.
