VS 2010 - Rich Text Box - Getting User Text In The Text Changed Event

Jan 20, 2011

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?

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

Apr 4, 2010

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

RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")

VS 2010 Transparent/Background On Rich Text Box Or Text Box?

Mar 17, 2012

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.

Limiting A Text Changed Event?

Jun 11, 2009

I have an number of text boxes and comboboxes on different forms. I have textchanged events which trigger a msgbox if the user enters invalid data(i.e. the number they enter is to big or to small). Is their a simple way to make the program not call the textchanged event when the form is loaded and the boxes get their initial value? Second is their a way to make the textchanged only be triggered when the user enters data not when the program clears the boxes?

How To Create ' Temporary' Graphics With Text Changed Event

Feb 27, 2011

I'm in an upper level industrial engineering class in which we're learning some entry level VB programming. We're working on building a program to solve the travelling salesmen problem (finding the shortest path through a collection of cities while visiting each only once) and I'm trying to add some 'fancy' to it so I can learn some more skills. The basic program is designed to load a bitmap file of a map into a picture box and a text file with the xy coordinates of any city positions. From there, the user can plot the cities with red squares, draw a random tour through the cities, or tour the cities by always visiting the nearest neighbor not yet visited. The modification I'm working on is a method of pointing out a specific city with a black square by entering the city's number (determined from the coordinate file) into a text box.

Private Sub TxtFindCity_textchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TxtFindCity.TextChanged
Dim ObjFindCity As Graphics = picShowMap.CreateGraphics
Dim City As Integer

[Code]...

So far, the program works, but I want the black squares (but none of the other graphics) that are created to go away once the text box is cleared. As of now they just hang around on the screen until I refresh the entire image with a 'clear map' sub. Any suggestions on how to accomplish this?

Allows The User To Define Text In A Rich Textbox?

Sep 14, 2010

I have an application that allows the user to define text in a rich textbox. I would like to give the user the ability to define text for one or more languages. I don't think this will be a problem using the rich textbox as it allows for unicode characters and DBCS (please let me know if this is incorrect). My question is, I display this text throughout the app in other controls as well, such as a listbox, label, etc. by acquiring the RTF's Text property (plain text). Are there problems with other controls displaying unicode/DBCS characters? I realize that I may have to toggle the font of the control in question depending on the language (I will allow the user to specify a default font per language).

One Sub Procedure / Change Text Color In Rich Text Box / Without Button Handler?

Oct 8, 2010

everyone! 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.

Developing A Program That Populates A Rich Text Box And From A Click Event On A Listbox?

Oct 6, 2009

I am developing a program that populates a rich text box and from a click event on a listbox. The data that is being loaded into the rich text box is located in a richtextformat file located on the hard drive. I noticed that when I entered a URL into one of the richtextformat files that it appeared that I was able to click on the text as if it were a link. So I wondered if it was possiable to click on that URL and open a web browser from the loaded richtextformat file? I have read several articles in regards to opening hyperlinks in rich text boxes which can open a web browser with a given URL.

Search For Text BackColor In A Rich Text Box?

Nov 23, 2009

I'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?
