How can I create a contructor for this.I have a constructor already in my class as follows :
Public Sub New()
Text = "Hello World"
TextFont = New Font(System.Drawing.FontFamily.GenericSansSerif, 10, FontStyle.Italic)

I'm creating a basic text editor and I wish to include the option to change the font, font colour and background colour of the text box. Is there a way I can ask VB to display a font/font colour selection box or do I have to populate a combo box and code it all myself?

View 3 RepliesI have a RichTextBox. I process all the formatting and everything works fine. There is an exception. When I have selected text that have two states of formatting in it, the SelectionFont member is set to Nothing. I notice that WordPad recognizes this condition
and kindof greys out the affected format.
Let's take this example:
This text is in Bold.
The rest of the comments here and not in bold.
When I select these two lines, the SelectionFont gets set to Nothing. WordPad sets the Bold button grey, but still clickable. If I click the Bold button in this state, the entire selection is set to bold. How do I achieve this same functionality?
I'm trying to make a wee word pad application in an attempt to learn visual basic.
I've got a combo box which has a list of fonts on the system:

I'm doing a lab for school, and I came across something I have never done before: create a default constructor within my class. It involves creating a private field to store the connection string, then create a default constructor that sets the connection string.
Here is what I have so far:

Private sqlconnection As String = ConfigurationSettings.AppSettings("ConnectionString")
Private Property connectionstring() As String
Get
Return sqlconnection

How do I apply 2 font styles to the text selected in a richtextbox? Used this method to change fontstyle:
RichTextBox1.SelectionFont = New Font(RichTextBox1.SelectionFont, FontStyle.Bold)
But with this method I can only apply 1 font-style (for example bold OR italic OR underlined, etc.) right? But I want to apply for example 2 front-styles, or just add the font style ( so I can add several front-styles to the selected text, for example the text is bold, and then ALSO make it underlined (with this method I can only change the font-style, only one font-style)), how do I do this?
Just do so:
RichTextBox1.SelectionFont = New Font(RichTextBox1.SelectionFont, FontStyle.Bold + FontStyle.Italic)

I am trying to convert a value from a radio list box that is populated by an access database. The database loads fine, I have no trouble with that. My issue is that I am trying to take the value of the radio button chosen and turn it into a font color. Therein lies my problem. I see that it cannot be a string, but when I turn it into an object, I get an error. I will note that I am using VS 2008 (Windows Vista x64), and the database is compatible with a 2002 - 2003 Access database. I am using ASP.NET for my programming, however, I am trying to program it in VB. This is my code:

I have an abstract class which requires a delegate to function. I pass the delegate into the constructor. Now that I have a non default constructor I need to call the abstract class's constructors from the concrete class which means that I need to use MyBase.New(...). I have included a quick example below.
Public MustInherit Class BaseClass
Public Delegate Sub WorkMethod()
Private _Work As WorkMethod
[code]....
I have tried to do this but I keep getting the following error: "Implicit reference to object under construction is not valid when calling another constructor".Can I not do what I am trying to do above? I initially had the delegate setup in its own setter method. But then I am creating a deceptive API because it does require a point to a method to work properly.
what's the rationale behind this limitation: Constructor call is valid only as the first statement in an instance constructor i want to pass an argument to my constructor which validates this argument and calls mybase.new according to this argument but it doesn't let me
example:
Public Class prob
Inherits System.ApplicationException
Public Sub New(ByVal problem As String, ByRef inner_exception As Exception)

I'm having a bit of trouble with my project here... and Google isn't helping very much. To put it briefly, I'm currently making a sticky note program (one fairly similar to Sticky Notes, for those of you familiar with Windows Vista or 7). It's relatively simple, as the "note" itself is basically a glorified Rich Text Box.
My problem is this: I obviously want to allow some for some customization with the font, however I don't want to use a standard full-on Dialog Box. So I designed a small form with 2 Combo Boxes--one for font and the other for size--and 2 buttons, "OK" and "Cancel". What I'm attempting to do is program this form (named dlgFont) to more or less be recognized as a Font Dialog Box. I've got some of it figured out I think, but I can't seem to put the pieces together in a way that actually works.In the code for my main form, I have this within the Class... stuff:
Friend WithEvents dlgFont As System.Windows.Forms.FontDialog
As for the Command Button that pulls up the dialog box itself, well, it's actually a Context Menu Strip Item... I'm not really sure what to put. So far I've only tried this:
dlgFont.ShowDialog
And for the Apply event, I've got the generic stuff:
Private Sub dlgFont_Apply(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dlgFont.Apply
If dlgFont.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.Font = dlgFont.Font
End If
End Sub
That's all I have for the main form. This is what dlgFont looks like: 'A limited-ability font dialog box.
Imports System.Windows.Forms
Friend Class dlgFont

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)
For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)
When the brand is selected I want another dropdown to appear under it with new chocies
For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)
And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.
