RichTextBox Formatting - Selection Font Gets Set To Nothing
Dec 15, 2010
I 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 have a richtextbox with multiple colored text in it. When I change the font, the color table is removed and everything changes to the default fore color. Anyone know of a why to preserve the color table and formatting when changing the font? I know I could build the RTF manually, but I really want to avoid that if possible.

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'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?

I have created an instance of a Rich Text Box:
Dim RichText As New RichTextBox()
I was able to write to it using:
RichText.AppendText("Text")
I was able to save the document to a file:
RichText.SaveFile("C:TempRTDoc1.rtf")
What I cannot find is how to set the font, and font size. IntelliSense doesn't help. Everything is "read only", meaning retrieve a current value.

I'm working on a word processor (yes, the thread with the quit forms and the count times open is the same word processor)
It's called iRobosoft Word. The 3rd version is at sourceforge and the 4th is in RC stage.
The 4th version is quite a major upgrade, but back to the topic.For font I used:
Private Sub Rich_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Rich.TextChanged
Font1.Text = Rich.SelectionFont.ToString
End Sub

I've developed a MySQL chat app that I have in my program. It works perfectly, however all of the text is the same color. I use a silver-on-black scheme. I'd like to do 1 of 2 things, whichever one is.. er.. "more possible". The first option would be simple - alternate each row's back color. So that one row would be silver-on-black, the next row would be black-on-silver, and so on alternating. Each row is separated by a "vbCrLf". The second option would be to merely bold or turn to white the info text. Here's the format of the chat messages: [{time} - {user}] {message}. I would want [{time} - {user}] to be bold and white. Are either of those 2 options possible? Well, I know they're possible

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 am trying to bind a RichTextBox to data from an XML file where text within a paragraph may be tagged with formatting tags. As an example the text may look like this:"The size of the area is 5000 m<superscript>2</superscript>".Text may also contain other formatting tags such as <bold> or <italic>:"The quick brown fox <bold>jumps</bold> over the <italic>lazy</italic> dog".

For a = 0 to 9
RichTextBox1.Text += "☻" ' add the smiley
[code]....
This when i ran it changes the first nine to the first colour in the array and correctly does the colour of the last smiley? could i for instance format the character first then add it formatted?

I have an Emailer in my Application and it has a richtextbox which the user can add fancy colours, font, pics etc... but when I send the email it doesn't send it as HTML. Is there a property in the richtextbox that lets me access the HTML code so that the email is sent as HTML and not just plain text. I need to be sending the emails as it appears in the richtextbox.
I am using the following code
Dim moApp As Outlook.Application
Dim oEmail As Outlook.MailItem
moApp = CreateObject("Outlook.Application")
oEmail = moApp.CreateItem(Outlook.OlItemType.olMailItem)
[Code] .....
And I get the following email Without HTML. Please look at the Emailer to see that it is formatted. So I need to send the content of the Emailer as HTML via outlook.

When setting the selection of a RichTextBox, the selected text is highlighted even though I set the HideSelection property to True. Once the RTB loses focus then the selected text is no longer highlighted. Programatically setting the focus to another control doesn't hide the selection, only physically clicking another control will hide it. So is there a way I can make the RTB not show the selection right from the start?

I need to use a richtextbox, not a normal textbox because of the way it keeps the caret position, from line to line. But I need to keep the text at the same font all the time even if it is pasted. At the moment I have it selecting the entire text and changing the font to the original (Lucida Console) but it look horrible when you paste into it as it flashes blue.

I have a RichTextBox with an OnChanged event. The OnChanged event should look at each line in the RichTextBox and if the line is of prime length colour it red, otherwise colour it black. How do I do this? I think it is possible to select from index a to index b and set selection colour, but I think this will lose my cursor position.

I have a rich text box in one of my applications (WPF). Now I want to store the data of the rich text box along with its formatting (e.g. bold, colored etc.) into a database (SQL Server). Currently I am storing the whole XAML of the text box in a database field. however, I am not sure whether this is the right approach.

I have two RichTextBoxes, each of which can have any sort of formatting. I need to be able to take the rich text from box 2, complete with formatting, and add it to the end of box 1, preserving the formatting of both box 1 and the appended rich text.
I've not managed to find anything usefull on this anywhere apart from hints pointing to manually re-building the RTF codes for the result (but no actual VB / C# / C code to perform this or similar).

How do you code selection of text within a RichTextBox. I tried the following code and nothing happens.I would think this should select all text within the RichTextBox.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.RichTextBox1.SelectAll()
End Sub
I would think this would select text from a start point to an end point.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
ss = Convert.ToInt16(TextBox1.Text)
se = Convert.ToInt16(TextBox1.Text)
Me.RichTextBox1.Select(ss, se)
End Sub

I need to set the color of the font every time I add text to the RichTextBox
I'm using. RtbResults.AppendText(DisplayPacket)
To add a new line of text, but each line needs to be a set color.I found this on the net but it doesn't seem to work in my VS11b RtbResults.AppendText(DisplayPacket,forecolor,backcolor,font)
Are these the correct overloads? can I do this another way if this doesn't work?I don't want to have to insert the text then go back and select and change its color.

I'm having trouble adjusting the font style in a RichTextBox and I've seen a few different approaches that talk about single attributes (like toggling bold on and off)... but I'm trying to make it so that my font class can adjust any attribute (bold, italic, underline).
I realize that Font.Style is a set of Boolean flags (a bitfield?)... but I'm not sure how to handle the attributes all at once.
Here is the troublesome code:
Public Sub ModifyFontStyle(Optional ByVal Plain As Object = Nothing, Optional ByVal Bold As Object = Nothing, _
Optional ByVal Italics As Object = Nothing, Optional ByVal Underlined As Object = Nothing)
[Code]....
What is happening to the font? The text should be underlined and in italics not strikethrough...
Is this a logic error or a simple misunderstanding on my part?
