When i parse text from a website ( Such as a description of something ) and it has symbols in it such as
Any symbol that get parsed out in the description looks like this on the richtextbox or any textbox I'm using a noob way to eliminate the problem by replacing each gibberish character to his normal font like this

I have some info in a listbox on another form. I want that information parsed to another form, and I would like to, for how ever many items there are in a listbox, create a button for every item and obviously parse the name to another label. I guess I would do this via an array.
View 2 RepliesI have a richtextbox control. It contains many lines of text (multiline is enabled). My goal is: When user clicks with right-click mouse, I'd like to display all the text of the line where the cursor is. I'm using this method to get the cursor's line:
Dim line As Integer = RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart)
But how do I get the text of the line? Should I copy the whole text to a string array , and then just print the relevant line item?
on a timer that ticks every 1ms have it:
if RichTextBox1.Contains "begin" then
change "begin" to "begin".bolded
end if

Is there anyway I could find text in a RichTextBox? I want to put the code in here
[code]...
I have a text box called "txtDescription" and listbox called "lstDetails" and a RichTextBox called "rttFullDes.
When the User inputs the search query into the description box(txtDescription) e.g "books" then it returns all the records that contains the word "books" and displays their Id in the listbox(lstDetails). When you click on the IDs it returns the full description in the Description box(rttFullDes)
This all works fine. But i want all the words to be hightlighted. i have got this code which i found.
Dim wordToFind As String = txtDescription.Text
Dim index As Integer = rttFullDes.Text.IndexOf(wordToFind)
While index <> -1

I searched this topic and set RichTextBox1.SelectionColor = Color.Red after click button1, and set RichTextBox1.SelectionColor = Color.DarkBlue for button 2 click event. But after I clicked either button, the text color was always black as forecolor set.
View 8 RepliesIs richtextbox can save a text within its control? What control in vb.net that could save the text being entered within its control paticularly, if any? I need somebody that could give me an idea on what control to use to save the text within the control. I'm not trying to save the text anywhere. I want to save it within the control. I don't have to save it with a filename and a path location. Just like this forum, which everytime you post and reply to a thread, you will have to enter your message in a certain workspace and after you submit, it will save within the control so everytime you open your thread you will see the messages. What control do I need to use in vb.net to do that? info especially the codes to save the text string within a certain control?
View 11 RepliesI'm trying to do two things. I have a Richtextbox which i'm continously adding text to from a standard text box. I want that new text to appear at the beginning of the existing text, not at the end of the existing text.I've got the following code but it's not working. The new text keeps going to the end of the existing text.
Dim newtext As String
newtext = TextBox1.Text
RichTextBox1.AppendText(newtext)

I have seen and used Text.split with a single delimiter such as " ",-","-".". However I cannot find a method which allows multiple delimiters. I need to be able to split a richTextBox's text into an array list.

I thought it would be fun if I could write vb.net or c# code at runtime and the interpreter would automatically parse it like python does it, so I made a little program, which would do something similar. Basically it looks like this:
InputArgs = Console.ReadLine()
ParseInput(InputArgs.Split(" "))
Private Sub ParseInput(Args as List(Of String), Optional TempArgs as List(Of String))

I know it's not a good system, but it show's the basics. So my question is: Is it possible to make vb.net or c# like python - interpreted at runtime?

So, imagine I have a RichTextBox control and a few buttons to allow the user to change the font size, set/unset bold, italic etc, and perhaps change the colour. Not much more than that. Can I then - in code - loop through the contents of the RichTextBox and determine which words are in bold or red or whatever, and where paragraphs start and end?
View 9 RepliesMy 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
View 2 RepliesI have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}
[code]....
I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with.
I have not been able to "Get" properties of richtextboxes that are in other forms in my MDI interface. I'm creating a document editor which specifically call for a richtextbox for each form.
