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

Different Font Size When Setting A Point 10

Feb 10, 2010

When setting a point 10 font size in VB6:


The reported size is 10. Can someone explain the difference here? My hunch is that VB6 is using a .75 step because my system is configured at 96 DPI, and .NET is not using said step, or not reporting its usage, but I'm not sure.

Formatting Lost In Rich Text Box?

Jun 7, 2011

I have some WORD files, which are formatted using bold, italic and colors etc. I want to copy entire content of word file into SQL Server table using Visual Basic.NET.I have a RichTextBox on my form and used datatype nvarchar(max) to store Unicode Hindi data. Everything is working fine... data insert and retrieve is OK, but formatting is GONE.

Below is the code to insert.

cmd.CommandText = "Update tbl_Camps SET CampName = '" & StrConv(Trim(txtCampName.Text), VbStrConv.ProperCase) & "', CampVenue = '" & StrConv(Trim(txtCampVenue.Text), VbStrConv.ProperCase) & "', CityID = '" & cboCity.SelectedValue & "', FromDate = '" & Format(dtpFromDate.Value.Date, "dd-MMM-yyyy") & "', ToDate = '" & Format(dtpToDate.Value.Date, "dd-MMM-yyyy") & "', LiveDVpkt = '" & txtDVpkt.Text & "', <strong>CampNotes = N'" & rtbCampNotes.Text & "'</strong> Where CampID = '" & frmMain.lblCampID.Text & "'"

Formatting Only Certain Values In A Rich Text Box?

Aug 26, 2011

I'm reading in values from an array of arbitrary size into a text box.  Easy enough.  However, in my application, certain values of the data are unusable and I'd like to give a visual warning to the user when this occurs.  Whenever the data
is either negative or greater than 10, I'd like to display that value in red.  How can I do this with a RTB?

Rich Text Box Font Color?

Apr 9, 2009

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.

VS 2010 Button To Toggle Between Bold/regular Font In A Rich Text Box

Oct 1, 2011

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.

Size Rich Text Box Using Size Of Text?

Oct 18, 2009

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.

Change Font Size For Label According To Text

Jul 27, 2009

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.

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?

I realise the font width will change dependent on the font used (which isn't an issue for my purposes), but as far as I know, the font height is usually consistent Accessibility/Large font settings won't be an issue with this application.

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?
