C# - WPF Definition Of FontSize?
Mar 1, 2010
I know that in WPF, FontSize = 1/96 of an inch (same as 1 pixel I think). Is the FontSize dimension the height, the width, or diagonal size of a character? I would guess it's the font height, but the Microsoft documentation doesn't really indicate what it is.
Also, is there an easy way to get the height and width of a font size?So it looks like the FontSize is the height, and the width can only be determined (without knowing the actual character) on monospaced fonts since proportional fonts have varying widths.

I've been trying to look for answers on how to do this, for days, but just couldn't find one. Maybe I don't know the keywords to look for. I hope someone can help me with this. Here's my problem. I'm trying to create a wordpad and I have two ComboBoxes (FontName & FontSize) and a RichTextBox. I'm trying to figure out how to get the FontName and FontSize of a SelectedText in the RichTextBox and be selected automatically in each ComboBoxes?

I can't set the FontSize of the Text in a TextBlock, since the TextBox is in a Viewbox. Why?
[Code]...
I can set the FontSizes of all of the TextBlocks but not of the TextBlock which is in the Viewbox.

I have a combobox which I want to use to change the font-size of text, but I'm getting an error.
vb.net Dim xfont As New Font(font_cbo.Text, font_cbo_size.Text, FontStyle.Regular, GraphicsUnit.Point)
Conversion to Type Single is invalid So I tried to convert the string to Single, but with the same error. If I replace the "font_cbo_size.Text" to a number, it'll work fine.

When you want to define a type you must say GetType(Type) ex.: GetType(string), but ain't String a type itself? Why do you need to use GetType in those situations? And, if the reason is because it is expecting a Type 'Type'... why isn't the conversion implicit... I mean, all the data is there...

When I right-click on function name and then press "go to definition" it takes me to the function definition. Is there any way to do this with just one click on function name,., is there some option ,or add-on for VB? that will be perfect, fast and furious

I made a copy of a program so I could 'play around' with modifying it. The copy is in a different project in the same solution, plus I renamed it so there shouldn't be a conflict-so why is Go To Definition not available in the copy? It's active in the original (and other programs) but grayed out in the copy. I've rebuilt the entire solution, including the copied program-and it still doesn't work.

I noticed in the code base I have to read that sometimes property definition includes an empty (). What's the meaning of that? And it has nothing to do with arrays.
For example :
Public Property TotalPages() As Integer

I have an .XSD that is made from a class so that I can pass to a webservice. It got it over to the webservice as an XMLSchema object and now I need to make it into a class so that I can make objects out of it on the webservice side. I know that XSD.exe is the answer but I'll be darned if I can puzzle out exactly how to implement this thing. I need it to do this conversion at run time so I need to put the code for it into my project and all the references I've seen to using XSD.exe talk about calling it from the command line.
My .XSD is below.
<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="[URL]">
<xs:element name="Field">
[Code] .....
In my project this is living in an XMLSchema object. How do I turn it into a class?

I have a class definition that I've seen other define properties that return collections of objects.
Public Property GetAllAdults() as Adults End Property I made the argument that this should be a method in the class, because it doesn't define an attribute of the class, and could not be extended with parameters. Is/Are there reasons why this should be defined as a property vs. a function?

When I specify <SoapDocumentMethod(OneWay:=True)> on my webservice it doesn't seem to get called. If I remove that the webservice works properly. Also, everything works fine on the development machine just not on the server.
Here is my web method:
<SoapDocumentMethod(OneWay:=True)> _
<WebMethod()> _
Public Sub Write(ByVal processGroupId As Integer)
xslClass.xslHelper.writeDatabase(processGroupId)

Why only the first parameter in the definition of VB.NET Generics uses the 'Of' keyword ?
For example I have here the the full code that LINQ uses for the Enumerable.Select() method :
<System.Runtime.CompilerServices.Extension()> _
Public Shared Function [Select](Of TSource, TResult)(
ByVal source As IEnumerable(Of TSource),
ByVal selector As Func(Of TSource, TResult)
) As IEnumerable(Of TResult)

I'm working a business layer (separate assembly) that will contain various business entities used in multiple client applications. One of the client applications is a WCF app that will need to serialize these entities. In order to properly serialize the entities, metadata for data contracts or for XML serialization must be added, but the serialization requirements may vary across applications.
Clearly I need the metadata separated from the class definition. So how do I add metadata to my entities for each separate application?

I call upon the VB ninjas out there. Here's my situation. I need to eventually be able to pass multiple models to a view. Currently I have a linq to sql class that, of course, has a bunch of generated model definitions. I need to make a model that implements multiple models. I somewhat understand how to do this in C#, but this project is testing my VB skillz. Here's some snippets from my linq to sql models. I need to combine these two into one model to pass to the view.

I have a base class which needs to define an enumeration:
BaseClass
- SomeEnum
I then need to create two derived classes from the base class and extend the values in the enumeration:
ChildClass1 : BaseClass
- SomeEnum
- SomeEnumValue1

In C# or VB.NET can someone provide the syntax to do this?

im sure im mis-wording the concept but here it is anyways. I know in CSharp you can do
el.AppendChild(new UISize(file, "TSize") { CX = 95, CY = 20 });
which declares a temporary bucket variable and then assigns the associate property values to the variable. Which then sends it to the XMLElement AppendChild method. What is this design concept called? What is the conversion to VB.Net? I have tried using my own online utility that does a 90-95% conversion rate from C# <-> VB.Net. It has failed in this instance, and so need a hand-up on what i am looking to do to convert this from C# to VB.Net. I would really like to not have to do a long-declaration of a variable with assignments, if at all possible.

In my attempts to understand vb.NET, one of the problems I have encountered is that I have not been able to find a concise definition anywhere for the Paint Event. So after many hours of researching and forum posts (and my own personal tests), here is my own definition (but it seems to fail in one instance, mentioned after the definition). I would like to create a final definition based on everyone's input, but keep in mind, the idea here is to STAY CONCISE. So here goes:
Explanation of the Paint Event
Whenever any portion of a control is UNCOVERED (except by the mouse pointer), the paint event fires. Covering of the control does not fire the event, because the covered area is not visible to the user, and is therefore irrelevant. The paint event is a messenger that alerts the program, via message, that some portion of the control has been uncovered and this message launches an OPTIONAL paint event handler (paint event procedure) written by the programmer, if one is needed to handle those situations when the event occurs. One possible situation is the most obvious...the need to redraw the uncovered region. A paint event procedure is the programmer's counterpart to vb6's automatic property, "AutoRedraw". But whereas vb6's solution was a simple and automatic redraw of the control, vb.NET's equivalent requires the programmer to define explicitly how the event is to be handled, whether it be a simple redraw or something more elaborate. This puts this event in a special category; it is not a user-desired event fired by some user-desired action...it is an internally generated event that acts more as a housekeeping "watchdog" to alert the program that housekeeping chores may have to be implemented because the user did something that was NOT DIRECTLY RELATED to a desired action. For example, when the user moves a window over a control in such a manner that a portion of the control is covered, then uncovered, this causes the state of the control to change even though the user did not specifically request it. It nonetheless may have to be dealt with, and this is managed via the paint event handler procedure.
The problem I have with this definition of mine, is that if the above is true, then why does the mouse moving across the control NOT cause the paint event to fire? After all, it is causing areas of the control to be covered and then uncovered. Is it because the mouse is a special case where the system puts the mouse pointer on a separate layer above the screen graphics, in order to prevent constant paint event messaging?
