I have written a test program and loaded a PNG image into it,
https://dotnetfiddle.ne t/XHwp7o
Pixel format = 32 bit color
Resolution of the Bitmap,
Width = 512 pixels
Height = 512 pixels
Stride of the Bitmap = 2048 pixels
Offset or Padding = (Stride - Width) = (2048 - 512) = 1336 pixels.
Size of the 1D byte array = 1048576 bytes
What would be the dimensions if...

NHibernate unidirectional one-to-one mapping problem.
I am trying to create a Unidirectional one-to-one relationship using NHibernate.
Example: An Order is given by a Customer.
Here, OrderN.Customer-field is intended to store Customer.ID as an FK. And this field doesn't have any unique constraint.Code:Customer{ID, Name, Address} OrderN{ID, Customer, OrderDate}
(The OrderN-table is given such a name to avoid SQL keyword conflict.)

GridView dynamic footer row creation problem.
I am able to create BoundFields and Footer-rows dynamically like this in my GridView:
...Code:protected void Page_Load(object sender, EventArgs e) { CreateGridView(); } private void CreateGridView() { GridView1.Columns.Clear(); DataTable dataTable = Book.GetBooksDataSet().Tables[0]; -
You didn't get me.
I was talking about BusinessObjects and O/R-Mapping along with ASP.NET.
Suppose I have a BusinessObject named 'Product' and it is O/R Mapped. Then, when I call Product.Get(), what should it return? Obviously IEnumerable<Pro duct>.
And if I want to use this BusinessObject named 'Product' in my asp.net code-behind, do I need SqlDataSource?
Now, answer my previous question...Leave a comment:

It depends on whether your domain provides the facility of hosting web applications.
If it does, then there must be a control panel for that hosting service and also there must be a control panel for managing databases and tables.
These control panels can be on the same UI or different.
Contact your web administrator to inquire for these things.Leave a comment:

I have just faced this problem while developing a code-generator this morning.
So a terrible guess by you.Leave a comment:
