Modifying The Rich TextBox

Sep 1, 2011

I've got to do some special things with a RichTextBox. I have to add syntax highlighting and I need

to be able to find out what character was added/removed/inserted at what position every time a key

is pressed. Is there some way to edit the existing, or is there a open source (.net compatible,

preferably VB.net) available for download? I've tried making my own, the problem is, it has to have

every function normally available and I don't have enough time to implement all of that.

Rich Textbox Rightmargin Property

Apr 27, 2009

Basically I'm writing a little piece of photo-editing software and I would like the user to be able to write whatever they want as a caption for the photo. VB then writes that text in a blank space created under the picture. Pretty straightforward, I've got it printing the text and it can adjust for height differences (i.e. multiple lines of text, smaller fonts, etc.).

My issues arise in the horizontal direction, I cannot make the Richtextbox large enough to represent the width of the photos (Some pictures have dimensions several thousand pixels wide and most monitors cannot display that many...) so I have used horizontal scroll bars (wordwrap off) to allow the user to scroll across and see all the text. Now what I would like to do is to set a limit to how much text the user can enter on a line (based on pixels to accommodate for various fonts/sizes) and it seems to me that setting the .RightMargin to just a little less than the picture dimension (to allow for padding) should do just that. [Code]

Allows The User To Define Text In A Rich Textbox?

Sep 14, 2010

I have an application that allows the user to define text in a rich textbox. I would like to give the user the ability to define text for one or more languages. I don't think this will be a problem using the rich textbox as it allows for unicode characters and DBCS (please let me know if this is incorrect). My question is, I display this text throughout the app in other controls as well, such as a listbox, label, etc. by acquiring the RTF's Text property (plain text). Are there problems with other controls displaying unicode/DBCS characters? I realize that I may have to toggle the font of the control in question depending on the language (I will allow the user to specify a default font per language).

Changing A Fore Color To Black In A Rich TextBox?

Jan 3, 2012

So I have a Vertical Scroll which enables you to change the Foreground color of the highlighted text inside the Rich TextBox. Here is the code of the Vertical scroll named Vscrollbar1:

RichTextBox1.SelectionColor = Color.FromArgb(VScrollBar1.Value)

It does indeed work. Then I have a button that makes the Rich Textbox not Visible. Using Richtextbox1.visible=False Then I have an open button, which makes it Visible again. But what I wanted is that the text inside the Rich Textbox to be color Black; but the color of the from the scroll keeps appearing. Here is my code for the Close Button:


I even changed it to this:


But still no difference.

Find / Replace Multiple Text In Rich Textbox?

Apr 12, 2012

I am trying to open up a text file that contains some text. I have 3 text boxes on my screen. What I need to figure out is how to replace multiple words (1 in each textbox) with text it finds in the txt file.

I can do this by using the single find / replace feature but I'm trying to be able to fill out the 3 textboxes and then click my find / replace button to have my Regex find each predefined word and replace it with what is in the text boxes.

Here is my code to get the find / replace one word at time feature. I've tinkered with this to just add more variables to my Regex but it doesn't seem to work.

Weird Behavior Setting Color In Rich TextBox

Dec 17, 2010

I am adding characters to a RichTextBox one character at a time and setting the format of that character after it is added. The following code is a distillation of the actual code but reliably repeats the problem I am having.[code..]

While that is odd to me and unexpected, where it happens in the code is even stranger. By stepping through the code, prematurely going to the End Sub and then displaying the form, I was able to determine that when i = 3 and the line "Me.RichTextBox1.Text
= Me.RichTextBox1.Text & "S" is exceuted, the color of the first two "S" are changed from Blue and Red to all BLUE.

I do not understand.a way to add characters to a RichtextBox and set the formatting of those characters?

This example is just color. I the real project I am setting Size, Color, Bold and Italics. I do not know if the solution to this color problem will affect the other formatting information.[code...]

Disallow Arrow Keys In MonthCalendar?

Mar 8, 2009

I want to update some things on the form when the user clicks a new date (or changes the month, which automatically selects a new date). If I use the DateSelected event, it seems to work as expected when I use the mouse. However if the arrow keys are used, the event does not get triggered. If I use the DateChanged event, it seems to go into an infinite loop. The message box pops up a zillion times when I click the arrow to change the month:

Private Sub MonthCalendar1_DateChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateChanged

The only problem with using the DateSelected event is that if the user uses the arrow keys, the event is not fired. I thought I could fix this by disallowing the use of the arrow keys, but I couldn't find anywhere to do that.
