How To Search For Texts With A Specific Font Size In Rich Text Box
Dec 24, 2010
How do I search for the words with the same font size (e.g. 15) in a rich text box and put the words into a list box? For example, consider a dictionary whose word entries are of size 15 and the rests are of 12. So how do I put all word entries into a list box and then the description (of size 12) in another list box. I am using visual basic 2010. I've tried regex but couldn't find a way of specifying the font size.Consider the bold letters of size 15 and the rests of 12.[code](physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3

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 have a program that checks for the color under the mouse pointer. I also stores what I think is the RGB (could someone confirm this?) value for that color in a Rich text box and next to that in a text box the coordinates of the mouse at that time.The idea is to be able to measure the times between the bounces of a tennis ball in a video. The background is black and the tennis ball is another color.I wasnt sure how to say "if color is not similar to black... Do this"So my plan was to set the richtextbox font color to itself - as it is an RGB value. But thats difficult, it wants to change ALL the text in the RichTextBox, not just the current Value.Basically Ideally I would like it if it recorded the times between significant changes in color of the pixel and displayed them.

I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")

I have a rich text box ('RichTextBox1') and a button ('BoldButton'), and have it set up so that whenever the user highlights some text in the box and clicks the bold button, that text becomes bold. That much I've figured out...
Public Class Form1
Private Sub BoldButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BoldButton.Click
Dim Bold As New Font(RichTextBox1.Font, FontStyle.Bold)
RichTextBox1.SelectionFont = Bold
End Sub
End Class
But I'd also like to add the ability that if the user highlights text that is already bolded, then clicks the bold button, that text will go back to 'regular' font. In other words, I'd like the 'bold' button to be able to toggle between bold and regular font.

I have a rich text box that have a paragraph in it (the parragraph may change). The user is able to decide what type and/or size of font he whishes to view the text in. My problem is that not more that an average of four words per line should be displayed per line. My idea was to size the rtb so that it automatically wrap the text to and average of 4 words per line. This I would do by determining the average width of a word (number of characters) in the paragraph, multiplying it by the width in pixels or twips of a character and then multiplying by 4 to get the average required length of a line. It does not need to be exact as long as I can get as close as possible to 4 words per line. Sample text:
My Father walks to the market every day to buy fresh bread and milk for the house.
Result expected:
My Father walks to the market every day to buy fresh bread and milk for the house.
Notice some lines may be slightly longer as long as the average is 4 words per line.My problem is that I dont know how to determine the width of a character in order to ultimately determine the width of a sentence.

I'm trying to make a program that can do some statistics on text in a rich text box. I'd like to count the number of instances where text appears with a certain back color, for example where text is "highlighted" with yellow.
There seems to be no function to get the backcolor of text at a specific index, you can only get the backcolor of text which is selected, like this:
Dim backColor As Color
backColor = RichTextBox.SelectionBackColor
This means, by applying this nasty trick, I would have to manually select every character in the rich text box before I can find the backcolor:
For i = 0 To RichTextBox.Text.Length
RichTextBox.Select(i, 1)
If RichTextBox.SelectionBackColor = Color.Yellow Then
yellows = yellows + 1
End If
Next
However, this takes a very long time, because the program has to select and deselect every character.
What options are there to speed up the process? Disabling the paint event?

I had an old program that I upgraded from VB6 to VB 2008. I am creating a program similar to it in VB 2008. There is a piece of code that I tried to enter into the program I am creating now from my old program. It tells the computer that if the label's text is a certain text that is on the clipboard, then the text size will be smaller.
If
LabelAbsent.Text = My.Computer.Clipboard.GetText Then
Label104.Font = VB6.FontChangeSize(Label10.Font, 8)
When I insert this code into my new program, it doesn't recognize the "VB6" in the code.
How can I get the same result in the program I am currently creating?

Within our application, some of the object's text are effected by users with "Large font" turned on under Control Panel>>Graphic Properties. I can't determine what is the trigger to this behavior. I have many forms including TableLayoutPanels, ComponentOne Sizers, some objects with DOCK=Fill, and AUTOSIZE=TRUE. I wrote a simple Hello World form, and it is not impacted by the "large font" setting.

The Code for that was:

I have a parse from Wikipedia saved in a text file in the following form: The town itself is situated to the south-east of the rock, and overlooks the Palaia Monemvasia bay. A small hamlet with about 10 houses lies to the northwest.The founding of the town and fortress of Monemvassia most probably occurred in the 6th century AD. The town was founded in 583 by people seeking refuge from the [[Slavic peoples|Slavic]] and the [[Eurasian Avars|Avaric]] invasion of Greece. From the 10th century AD, the town developed into an important trade and maritime centre. The fortress withstood the [[Arab]] and [[Normans|Norman]] invasions and conquests in 1147. Cornfields that fed up to 30 men were grown inside the fortress.What I need to do is to extract specific texts from the parse given the header names. For example, if I type in a textbot Geography I need ONLY the geography text returned.

What I am doing is creating a simple login and register system. I am going to save the information of each user into a text or ".dat" format and have them placed into a folder called "accounts".The small problem that I have is the "Forgot Password" option. I can't think of how to search all the documents for the e-mail or the username.So basically I need to know if it is possible to do a small search for the e-mail through all the documents in the "accounts" folder.
-I know another option may be databases...but I don't completely know how to use these.
-I have general knowledge of arrays
