I have a richtextbox And I have programatically added lines of text to it...I would like to not be able to delete the text I have added, but add more text after. So far I've tried a timer to refresh the text in the richtextbox so that it couldn't be deleted but I couldn't add any text after..

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

I'm using a richtextbox in vb.net. I need to maintain the text formatting while inserting a new entry.I have this issue solved although I am having difficulty with getting a new line between my new text and the prior existing text.Most solutions online presume you're working with rich textbox. text which accepts controlchars.lf, vbcrlf, and chr(10)... even chr(13) adds one single newline.How do i get the newline in rtf formatting?I prefer to have the new text entered at the top of the richtextbox as a user should see the latest update first.In addition, if this can be done more elegantly, I'm open for suggestions.Where you see controlchars.lf is where I want an rtf-based new line to show up.

For sometime now whenever I am in need of formatted text I have been using RichTextBox control and save data to RTF format. However lately I started using RTF editor control that allows you to insert images into rtf. And although this works, the file sizes grow immensely.I was wondering if nowadays there are any better alternatives (preferably available for free) that people can use in windows applications for viewing and editing documents.

View 3 RepliesThis is my first post at the forums, if I did something wrong making this topic Okey so here is the deal. The program task is to take 50 codes including letters and numbers. Take them and insert them into a webpage(webbrowser1) witch is designed to deal with these codes(3 fields). To check if the codes is valid etc.
Here is what I got :
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox1.Text)
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox2.Text) '
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox3.Text) '
What this does it takes textbox1.text input(first part of code) and inserts in the first field at the website.The to others to exactly the same.But instead of having 3 diffrent texboxes I want it like in this pic.
Just had a question regarding a Windows Form Application in Visual Studio 2008.I was wondering if it is possible to have a RichTextBox and have a < (previous) and >(next) button. When the user selects the Next button, a new blank RichTextBox will be displayed, when the user selects previous button, the prevoius RichTextBox w/ whatever text was in there before will be displayed.

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.

I am bringing in data to a richtextbox but when I bring it isn't aligned like i thought it would. Is there a property or something i need to enable to get this to work. Here is how I would have imagined it to work:-I figured this wouldn't display correctly.this was just an example, but was hoping to have the asterisks display even with the last asterisks on the first line and the slash on the last line.
/************************
* *
* Some Text *
************************/
The text when i look at the .Text Property and click the magnifying glass shows it like i would imagine but within the control itself the alignment is all over the place and doesn't make much sense how it is doing it. If i bring the same text file into notepad it all looks fine and is also aligned correctly.what I need to enable to get this to work?
I should also mention that I thought maybe it had something to do with tabs, but when i view the .rtf property for many of the lines that should be aligned still are not even without tabs.
I would like to make a line of text in my richtextbox multicolor. I have tried various implementations provided on the web and read up on SelectedText and other topics but can't seem to get it to work the way I would like to.Here is what I have so far
RichTextBox1.Text = "This is black "
RichTextBox1.SelectionFont = New Font("Microsoft Sans Serif", 8.25, FontStyle.Bold)
RichTextBox1.SelectionColor = Color.Green
RichTextBox1.SelectedText = "[BOLD GREEN]"
RichTextBox1.Text = RichTextBox1.Text + " black again"
The colors I want are stated as the text. What happens is: the entire line turns green, "[BOLD GREEN]" appears at the beginning of the textbox instead of inline. I want it to read like this: "this is black" as black. "[BOLD GREEN]" as green and "black again" as black.
i need it urgently for this code. i have data input to richtextbox and i want to average up the data? how to do this?
