View 25 RepliesI want my text box to filled by an alphabet first then the remaing characters can be anything. Also i have drop down which is having arithmatic functions.(< ,> , = ,+ etc) If the user selects < or > then the value entered in the text box should be numeric. and if the user selects "=" then the textbox value should be string.
View 1 Replieseveryone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.
At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:
Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged
[Code]...
Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.
How can I change certain text's color (like Visual Studio does with "Public Class" or "Public Sub") is inside of a Rich Text Box?

What would the code be to just put the words "Hello World" into a textbox and have Hello be red and World be green?This code doesnt work.
this.richTextBox1.SelectionColor = Color.Red this.richTextBox1.text += "Test"
I have a program that checks for the color under the mouse pointer. I also stores what I think is the RGB (could someone confirm this?) value for that color in a Rich text box and next to that in a text box the coordinates of the mouse at that time.The idea is to be able to measure the times between the bounces of a tennis ball in a video. The background is black and the tennis ball is another color.I wasnt sure how to say "if color is not similar to black... Do this"So my plan was to set the richtextbox font color to itself - as it is an RGB value. But thats difficult, it wants to change ALL the text in the RichTextBox, not just the current Value.Basically Ideally I would like it if it recorded the times between significant changes in color of the pixel and displayed them.

I am trying to create a viewer for files with large (sometimes over 2,000 characters) records. I want to use the rich text box control and show a given record in rows of 100 characters each. I have set the font to Courier New and sized the RTB appropriately to show the records correctly. However, if there is a record with 80 consecutive alpha characters followed by a space, then 120 consecutive alpha characters, the RTB separates the line at the space, as if there were a vbLF there. This happens in other cases, but I haven�t been able to figure out how the RTB decides when to break the line.

I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple

On the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.

I'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

View 1 RepliesOkay, so what I want to do is directly output formatted RTF text to a Rich Text Box control in VB.NET. I don't want to find the text, select it and color it as it is not practical for what I'm doing. I've tried outputting RTF code but that isn't working either. Can I actually do this or will I have to write a dll?
View 1 RepliesI am working on an applictation to scan windows files to check for missing files, i have a couple questions on how to do this.I would like to use the %systemroot%system32 that way that it doesn't matter what drive letter it is, i'm not sure how to do this because when i tried it, it told me the file i was looking for didn't exist (in this case C:windowssystem32 undll32.exe) which does exist. Is there some way to use the %systemroot%?
Also, i am trying to print the resaults to a rich text box such as if rundll32.exe is missing put in the box "rundll32.exe is missing". How do I allow it to write it in the box, I tried the print command, but it didn't work.
I've been wanting to create a look like the attached jpeg Ive been looking around for a few hours for a solution to make text boxes transparent or have a background image. I've found a few projects on this form and elsewhere which include transparent text boxes, but every time I try to use it the way I need to--with the text box over a picture box--there are always various rendering errors. Most of the time, the text box is transparent if its just placed on the form (not over any other controls). But when I place them over other controls (like picture boxes), the 'transparent background' always take on the color of the form background.
This is one that I was trying to use. I found a few others around, but they all had the same render errors more or less.[URL]...I figured transparency or background images would have been supported natively. Anyone have any ideas? Maybe I missed something in my searches. I didn't really see anything which adds background images in text boxes (rich or otherwise). At this point, I'd just like anything that works, so it doesn't really need to have transparency--just a simple background image would be great.
