So - I have some text in an RTF control. I want the user to be able to highlight text and apply an attribute. The following code is placed into a button called BOLD and seems to work nicely:
If rtfText.SelectedText.Length > 0 Then
rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Bold)
End If
The code above will turn the selected text bold.
But then the user selects the Same text and with the following code placed into a button called ITALIC it removes the bold attribute and replaces it with italics.
If rtfText.SelectedText.Length > 0 Then
rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Italic)
End If
Since the users actions are separate - I can not know that they want BOLD and ITALIC, so how do I make sure I keep the existing attribute on the selected text (which, by the way could be part bold and part not-bold) and add italic?
Somehow I need to add the italic attribute to the selected text, not simply replace all attributes with italic.

I'm trying to force an inherited class to use a custom attribute. I'm creating a class library where the user who wants to create an item will do so, but be forced to add an attribute (or visual studio will automatically add the default attribute) to their inherited class. Here is what I'm hoping to achieve:
BaseClass.vb:
<CustomAttribute(10)> _
Public Class BaseClass

How can we apply attributes to class fucntion using AOP in C#?I am slightly not clear in what context AOP should be used? As we can use AOP for logging purpose, security(Authentication), please suggest some other scenarios where we can take benefit of AOP.Is AOP can be use to share data among different running threads in application process?
View 2 RepliesI recently posted a problem with a game that I am making, I have worked on it but have become stuck. I am having trouble with creating an object from my class what I need to do is apply this class to multiple picture boxes so that I can have them moving on screen at the same time. I am unsure on whether or not I have set up the class correctly and am unsure on how to apply it to multiple picture boxes.
This is the class:
Public Class enemycar

How do I apply effects such as a DropShadowEffect class to a TextBlock Run element in WPF?
Think of it as a way of highlighting certain areas of text in a TextBlock where the Run element is located, but applying an individual effect to that area instead.
I was knowing that For Each loop can only be applied to those classes that implement IEnumerable interface . But recently i accidentally wrote a code that is using For Each on my class's objects collection and my that class is not implementing IEnumerable interface .Below is the sample code that i am testing on :
Sub Main()
Dim personList() As Person = New Person(2) {}
personList(0) = New Person("s1", "s2")

I've setup an ItemTeplate like so in a GridView:
<asp:TemplateField HeaderText="Building">

There is definitely a Building entity in the pbu_housingEntities?
I am trying to set the class attribute of a list item on page load. Dim liItem As HtmlGenericControl = DirectCast(Page.FindControl("default"),HtmlGenericControl)liItem.Attributes.Add("class", "active")
This code doesn't work, not quite sure why.This is the error it is generating "NullReferenceException: Object reference not set to an instance of an object"
Is there a way I can assign a value to a class attribute using a constant? would like to do this so that I don't have tocode a constant value in the attribute and then again inside the class.

ToSerializable is it possible instead of marking a Class with the <Serializable()> attribute?

View 4 RepliesI have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?

I wonder, what is the most elegant way of dealing with the dbnull situation. I have a class, with attribute, let's say: "End_Date", which is being read from database. Type of this variant should be date, but as it's the "End_Date", there might be the situation that something haven't ended yet, and in the database in this field I have a null value.
Right now a deal with the problem this way:
Dim mEnd_Date
...
Public Property End_Date ()
Get
End_Date = mEnd_Date
End Get
Set(ByVal value)
mEnd_Date = value
End Set
End Property
But I am not sure if that's a good way as I don't declare variants as any datatype?
