Rich Text Box - Load Specific Text In The Rich Text Box When The User Load The Form?

C# - .NET Expanding An Image While Preventing Clicks On The Form?
Dec 15, 2011I am developing a WinForm application using VB.NET (I am fluent in C# as well, so post in whatever language) and have run into some trouble. I have an image on my form that I would like to expand when clicked on. I have all that logic set, but I want that when it expands, the user has to click on an 'X' in the upper right corner of the PictureBox to close the expanded image. While the image is being displayed, I don't want the user to be able to interact with the rest of the UI on the form.
Basically I need something along the lines of (pardon me for switching to HTML but I know this works there) creating a div that covers the whole screen, making it opaque, putting another div on top of that, and then putting the image and the 'X' button on top of that. I have tried using opaque forms (didn't work), and panels with a transparent backcolor (didn't work either). I've resorted to taking a screenshot of the form, setting it as the image of a PictureBox, and putting the PictureBox on top of that. However, that seems like way to much overkill.
My current layout is MainForm -> Dynamically create new Form and add it to Main Form -> Add PictureBox to Dynamic Form and set its image to be a screenshot of MainForm -> Add a PictureBox on top of that PictureBox and set its image to the expanded image that I want

View 6 RepliesPreventing Carriage Return In Multiline Text Box?
Jun 10, 2011I have a textbox, and it's set to multiline, so a user can enter a few sentences. The problem is, if the user hits the enter button while in the textbox, it's starting a new line. This data is being saved as a text file, and it's causing problems when the text file is loaded back into the app, causing load failures.
I'd like to completely make the enter key useless when the textbox has focus. Or, if they hit enter, it tabs over to another button.
Here is some code I used to make the enter button behave more like a tab-
Private Sub txtCallNotes_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs)
If e.KeyCode = Keys.Enter Then
Me.btnSubmit.Focus()
End If
End Sub
The problem is, the enter button still does a carriage return, causing a new line.
In the properties, Accept Return is False.

Jan 20, 2011I'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.

View 5 RepliesOne Sub Procedure / Change Text Color In Rich Text Box / Without Button Handler?
Oct 8, 2010everyone! 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.

VS 2010 Transparent/Background On Rich Text Box Or Text Box?
Mar 17, 2012I'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.

Search For Text BackColor In A Rich Text Box?
Nov 23, 2009I'm trying to make a program that can do some statistics on text in a rich text box. I'd like to count the number of instances where text appears with a certain back color, for example where text is "highlighted" with yellow.
There seems to be no function to get the backcolor of text at a specific index, you can only get the backcolor of text which is selected, like this:
Dim backColor As Color
backColor = RichTextBox.SelectionBackColor
This means, by applying this nasty trick, I would have to manually select every character in the rich text box before I can find the backcolor:
For i = 0 To RichTextBox.Text.Length
RichTextBox.Select(i, 1)
If RichTextBox.SelectionBackColor = Color.Yellow Then
yellows = yellows + 1
End If
Next
However, this takes a very long time, because the program has to select and deselect every character.
What options are there to speed up the process? Disabling the paint event?
