What is the best way to set the default value for 'bit' or boolean data types in SQL express? I am using the data base explorer in VB Express 2008 and the only way I seem to be able to do it is by using ((0)) for false and ((1)) for true.

In the code above, if there are no children (the ChildrenPath property returns NULL), nothing is rendered in the view. In the code below, when ChildrenDataSetPath is NULL the XamDataGrid still gets rendered. How do I achieve the same for a single object (as opposed to a collection) as the datacontext?
<DataTemplate DataType="{x:Type vmb:clsPersonViewModel}">
<igDP:XamDataGrid DataSource="{Binding Path={x:Static vmb:clsPersonViewModel.ChildrenDataSetPath}}">

I have XML files I am trying to read and import. I have XSD files and have used the XSD.exe tool to create classes for the elements found in the XML files. The problem I have having is that the same file structure can be used for different "message types" (different data structures for different purposes). Because of this, the structure of the file is roughly this:
<Envelope>
<BatchID>SomeNum</BatchID>
<Messages>
[code]....
Where the Order element is, it could be one of a few different element types in the message based on the message type. Currently, I'm trying to read an order file.The XSD tool created all the classes fine but it creates an 'Item' object for that inner element and makes it one of the other strong types during the deserialization, so I end up with something like:
Envelope.Messages(0).Item
Item is just an object and is not strongly typed until the deserialization happens. If I look at the data in Item in a watch window during debugging, it shows it is the strongly typed class and has all the data in the members I would expect to see, but I can't seem to access them by name or set an instance of the strongly typed Order class equal to the Item object. Any attempts I've made so far to read the data have resulted in the "No default member found for type 'Order'" error.
Im trying to set one variable equal to another but it says "No default member found for type 'Decimal'" what does that mean?Both the varuables are deciamls, one is a regular decimal that I declare in the sub and another is an array that I declare in the class. The line is:
tempx = xo(i)
this is in a for loop with i as the variable.

How do I make a program a default program for a file? As in if I had just a basic .txt file editor, I could make the program the default program for the extension .txt. I have tried just doing it in Default Programs, in Windows 7, and Windows XP. But when you click on the file it opens the program, but does not load the file. I plan on actually releasing the beta 2 a Office Suite I created.

I'm making a manually started screen-saver-esque program, and I need the "Black screen" form to be full screen, totally black and border-less.
I have so far managed to fix the last two criterea with changing the border style and form back color, but how do I make the form default full-screen?
The only settings I could find were things like "Manual" and "Center Parent". I'm probably just missing something obvious, but how do I make the form full-screen by default?
I am creating a button to save text files (Visual Basic 2005 and Windows XP). I made the following loop to give a default name for the file before saving:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'This loop is supposed to name the file "file10.txt", and if such a file exists it is
supposed to name it "file20.txt" then "file30.txt" etc.
Dim myFileName As String
Dim i As Integer = 10
myFileName = "D:filesfile" & i & ".txt"[code].....
However, the app gets unresponsive only after one round in the loop (when the file name is "file20"). The loop gets stuck at the following line:
If IO.File.Exists(myFileName) = True Then
This line works only once and after that it becomes unresponsive.
Basically what I would like to do is take a screenshot of a portion of the screen based on coordinates taken with the mouse left button click.

Let's say I have a ShoppingCart class, which has a ShoppingCartItem List:
Public Class ShoppingCart
Public Property CouponCode As String
Public Property Items As New List(Of ShoppingCartItem)
End Class
[Code]....
However, when I submit the page, no values are picked up, not even the CouponCode field. The model object is empty. What gives?
Ultimately, my goal is to add/remove items clientside via javascript and then have the modelbinder pick up the changes automatically when the page is submitted.
Update: I was just missing the Property keyword from my model properties declarations. It's too late, and I got to get some sleep. :)
