RichText And Disabling Text Style
Jan 8, 2012
I know how to enable the selected text style (bold, italic, underline...), maintaining other styles. For example, If I want to enable 'bold,' the following line of code works. [Code] I can also remove all text styles. I also know how to find out whether or not the selected segment of text has a style. But how do I remove the selected style without removing others? How do I disable only 'bold' while the selected segment of text has other styles like 'italic' and 'underline'?

Im trying to put text into a RTB using buttons. These then auto fill in notes etc in the RTB to say a user did X at X time and date. This was working fine when i did it for a plain text RTB. But when using RTB i have had to change my origional code from:
Private Sub Button20_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button20.Click
NotesBox.Rtf = Me.NotesBox.Text & vbNewLine & Date.Now.Day & "." & Date.Now.Month & "." &

This is my second post and today I have the following problem:I want to make a Steam Gamertag Maker ..
1) I have a RichTextBox.
2) I have 8 buttons each representing a color (red, green, yellow, blue, teal, pink, white and black ..)
3.1) I enter some text into the richtext box.
3.2) I select part of the text.
3.3) When I press a button, e.g Blue and the selected text changes to that color.
3.5) I have a copy button, that copies the content of the richtextbox .. and that is where the problem starts .. (The copied text has no color and so on .
4) If I press, for example the Blue Button, I want that the following text "^4", is written just in front of the selected text and that the selected text is colored blue at the same time. The other text should not be affected by those adjustments ..
5) If the "^4" is inserted, it should be hidden
6) If everything is colored, I press the copy button and it should copy the whole text, including for example the "^4" ..
7) I want the "^4" to be hidden, because it looks better, but if I copy the content of the RichText box it should be included ..

I used to use Visual Basic 6.0 to look up a webpage with Web Control, then I would paste the Text from that into a RichText document....then I would parse it down to what I was looking for. Now that I'm getting back into programming again, I have been trying to repeat this process with Studios 2010...but with little success so far.

I am creating an application and am very new to VB. I have 4 buttons on my form which is like my applications main menu. I would like that each of the buttons behaves in the following way when there is a mouse rollover: The Button back color is changed from the default to Red The Button text is changed to Blue, Bold, and increases in font size I would also like all the buttons to go back to their initial state when the mouse leaves.
Another thing, instead of me writing code for each of the buttons event handlers (Mouse Hovers, and Mouse Leaves) is there a way I can write this code once, maybe as a function and then always call it for any button that I create from here on so that any new buttons take on this behaviour.

The instructions I'm following indicate that when user clicks the Add This Item menu item for a new order, the customer information should be disabled so that the state cannot be changed until the next customer.I've tried to validate that all the customer information fields are filled when user clicks Add This Item menu item. The trouble I was having was that even when you were alerted that you didn't fill one of the fields, you clicked on the message alert and then the customer fields were disabled before you could fill the empty one.
I've tried to make an if statement which checks if some are empty to alert else if they are filled then disable. This doesn't work either. I get Conversion from string "" to type 'Boolean' is not valid. I'm not advanced enough to understand this. I just know boolean means true or false or yes or no. I'm not sure the best way to handle this situation. I don't even know if locking the user out is wise since they might have wanted to correct something wrongly entered but my instructions are to validate that the fields are filled and then disable the customer information. I need to follow the instructions exactly.
This is what it looks like:
Private Sub AddThisItemToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddThisItemToolStripMenuItem.Click
'Declare local level variables.
Dim Quantity_Decimal As Decimal

im trying to disable a button until anything has been entered into two text boxes simultaneously.
So far i have tried:
If String.IsNullOrEmpty(TextBox1.Text & TextBox2.Text) Then
Button1.Enabled = False
Else
Button1.Enabled = True
End If
However it doesnt work simultaneously, the button will become enabled if i enter anything into either textbox, i cant have any of them left blank.

I need my application to do some fairly simple C-style curly brace text parsing. The text style is similar to C or C# in that it uses curly braces to define blocks of code.[code]As you can see it also uses C-style comments (//) and can (actually always will) use nested blocks, but only up to one level of nesting is allowed. As you can also see, the code does not have to be formatted neatly. There can be spaces before any opening or closing brace and it will still be valid.The text however is not similar to C or C# in a few ways:
- it does not need a semicolon ; after each 'statement' (abc, def)
- the block names will always consists of one single word except for the possibility of comments behind that word.
- the event names may contain more words
- the block and event names do not end in parentheses ()
I am telling you this because I have a C and C# parser which I can use (it came with the text editor control I am using) but it does not recognize the language I need as valid C or C#, because the block names do not end in parentheses, and the commands are not ended by semicolons. Therefore it keeps doing things wrong (it should automatically outline the text, auto indent it, smart format it etc) because it is expecting C syntax exactly, and it sees my language as loads of syntax errors (missing semicolons etc).So, I need a way to parse the language manually, and it needs to be pretty fast too. Some of the things I need include:
- Getting an entire block (including nested blocks) just from the block name (identifier?).
- Getting all block names (nearly had this working with the help you guys gave me but not completely there yet).
- Getting all event names in a specified block.
- Getting an entire block (or just the block name) just from the current cursor position (if the cursor position is somewhere in block2 I should be able to identify that and return 'block2').
- Probably more...
Then I thought, wait a minute, this C-style language is probably the most used language style, so there should be LOADS of examples online... So I started googling but did not find many relevant things.Is there anyone who has any knowledge about simple language parsers? Anyone who can help me do the things I wrote above..? I realize I am asking for a lot, but the language is pretty easy and I cannot imagine that it is extremely hard to parse it quickly. I also don't require any syntax error checking; all I need are the few things above (mainly retrieving the block names and event names).

I am trying to make a style that only gets applied if the parent element of the element that the style refers to, has another specific style. Kind of like in CSS where you can do ".class1 .class2" to specify that the "class2" theme only applies if it is within an element with the class "class1". I do not wish to use any form of external DLLs or libraries for this task. I want to know if it's possible to implement on my own.
I've tried using MultiTriggers with no luck. I have a style that applies to all TextBlocks. I want the textblock to do the following: If the font-size of the textblock is 11 and the parent element's style is "PinnedSuggestion", set the foreground color to "#FF505050". If the font-size of the textblock is 11 and the parent element's style is "Suggestion", set the foreground color to "#FFCCCCCC". The conditions that I have tried to write to make this work, are as follows (the font-size condition is true, but the other one is not). The conditions are inside a style that applies to all textblocks in general.

Is there a way to check if a RichText box is on the bottom? I don't think this is working:
Code:
If RichTextBox1.Selected = Len(RichTextBox1.Text)
'It's on the bottom
End If
What I am doing is, having the text go to the bottom (like a chat client) with this code:
Code:
RichTextBox1.SelectionStart = Len(RichTextBox1.Text)
RichTextBox1.ScrollToCaret()
However, if the user is looking at what was sent before, it scrolls them back to the bottom.

I have a task to provide a RichTextBox control that behaves like a tooltip, ie:
1. Hovering when mouse moves
2. Remove after N seconds (customizable) or if the user closes it (by "X" button)
The regular tooltip does not provide a RichText capabilities (else I'd take it)
Should I take a form and put a RichText inside, and set the form properties accordingly? Something else?
