.net - WPF RichTextBox - Iterate Through The Text's Words And Change Their Content And Formatting?
Nov 1, 2010
I have a WPF RichTextBox which contain in its FlowDocument both text and images. I need to iterate through the text's words (those which builds the text which the user see on the screen) and change their content and formatting. For instance, change the word "room" to the word "home", applying to the last a red color.
I need to change words whether they are formatted or unformatted.For instance, if a word is in Italic, colored, or just regular black text, it makes no difference for me.Each word will be replaced with one which have about identical length, so I don't want that this operation will effect the general page layout. All images and other objects should remain at their positions.It is preferred that the process of this operation will not be visible to the user. Only its result should be visible (i.e, no visible selections of text).If this operation can be done either directly on the FlowDocumet or with properties/methods of the RichTextBox, the simple one is preferred (but exmaples for both will be ideal).
Ok, Im developing a scripting tool for the program "FPS Creator". The scripting uses of course commands which are split into to groups (Action and Condition)
Anyway to the point :
I need the Actions and Conditions to be coloured so the user knows when the command is correct or incorrect.
So, I've started to work on a big project that involves analysing text and changing that text into a whole new group of words that relate to it and say pretty much the same thing but through different text, I'm just looking to see if there is a thesaurus or dictionary I can access through visual basic... instead of having to right every single word in the english dictionary out.. or if there is any shorter way I could do this.
i want to create a html editor. to get started, i want the app to be able to find certain words, and change the font/color/size/etc. as for <a href=""><b> and so on, without changing the rest of the text after the selected text was modified. i'm sure that it has something to do with RichTextBox1_TextChanged for text that is being typed and just a button click for modifying selected text.
My application appends incoming report data onto a RichTextbox control. As more text arrives from an external device, the thumb initially fills the trough and as times goes on, the thumb diminishes in size. This is expected behavior.A modal dialog box allows the user to cancel the file download but since it's modal, the user can't scroll down to see what the last text that was appended.Is there a property/event/method that will show the most recent/last text in the RichTextBox control, rather than the initial text as I have it displayed now? The user would be able to see the text drawn real time without having to use the thumb to accomplish
I have a label in a master page (sample.master) called lblHeading.I want to dynamically change the text of the label when I load the content page.I need to do this because I want to change the heading to something meaningful but only after I know about the content of the page.
Trying to change the color of more than one of the same text within a RichTextBox. [Code] The above code searches for, and changes the color of all "Boat"s found in the RichTextBox. There are a few problems, such as: If you were to go back to edit the RichTextBox and place your cursor in front of the, now blue word, "Boat" and type then all of your text would be blue. Also, the text you wish to change the color of in the RichTextBox MUST be Exactly the same as: "Search1", aka "Boat", capital letters and all.
I have another application that i'm currently building...
It basically is a "check list" for installed program's, and files. I image machines on a daily basis, and me making this application will save me hours, and hours of time.
"This is a test . This is the second test . This is the third test . This is the final test"I know how to do this using SelectionStart etc. However this limits what I want to domagine that the 4 sentences are stored in an array, where array(0) should be always bold,array(1) italic, array(2) underline and array(3) normal.
I try to create a simple IrcClient.If i get a Message over the Irc, the Sub OnChannelMessage gets Enabled and should give out, what someone wrotes.The Sub:
Public Shared Sub OnChannelMessage(ByVal sender As Object, ByVal e As IrcEventArgs) 'Form1.RichTextBox1.Text() = "[" + e.Data.Nick.ToString + "]: " + e.Data.Message Form1.SendText.Text = "Test"[code]....
I am attempting to change the color of certain text while i am typing in the richtextbox area my only problem is. because its a selection if i keep typing then whatever is selected will be removed.[code]...
I'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.
I want to change the text size in a richtextbox without changeing the font style (whether it is bold, inderlined or in itallics.) I have used this code, but it wont work, it just changes the font style to normal:
I already exporting contents of my datagridview to excel and word but I need to format one of the column of my datagridview. That column is "Amount". In my datagridview, it displays like this "122234". I want to display all the value in that column in this format: "122,234.00". I already tried to format it to number("N") in my datagridview but when I exported it to excel and word, it shows no format.[code]
I've been trying to convert my VB6 code to VB10, I'm stuck on how I should write it so I can pass a font name to my
function, So far this is what I have and not sure where to go from here. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I have a Dynamic Fields comming from database. These fields populated on RichTextBox after changing the color.Means Different Fields in Different Color.
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 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".
