wpf - Get the size (after it has been "streched") of an item in a ViewBox -

-

Consider the following:

We say that the window is 1024x768 And the view box fills the entire window, this means that the text box on the screen is really big.

I want to get the size of the text box because it is currently on screen.

Update: I might get real-life of ViewBox and make it your child's true wide Which divides me into the current scale and will expose it as a property in some way but I'm not sure it's the best way to do it.

In this way you ScaleTransform to ViewBox Applies to your children: 

  var child = VisualTreeHelper.GetChild (view box, 0) ContainerVisual; Var Scale = Children Conversion as ScaleTransform;   
 Here is the  view box  that sits in the text box. After this you can only increase the  scale.ScaleX * textbox.actualwidth  and you may find the size in the screen coordinates 
 
 but it becomes easy! To get the size of that text box directly in the screen coordinates: 
 
  textbox.PointToScreen (new point (textbox. Real point, text box, realheit)) - Text box. Pointtooscreen (new dot (0,0))

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
