Format Text - Rich Text Box - Where The User Will Be Entering Information - The Text Is Black
Aug 11, 2011
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?
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")
I am saving the text in a Rich Text Box(vb.net) into the DB. It saves fine..(Datatype--long text). The text has modified appropriately in the DB. But, when I try to retrieve it, it says, invalid format or cannot convert to integer (If Date of Birth is in the Text) or some vague errors...Please help THE ERROR : The file format is invalidHERE IS THE ACTUAL TEXT in the RTB --Notice the Bold and the UnderlineVITAL SIGNS:
I've been trying to get something done In a form i got 1 combobox and 7 textboxes and 1 ritch textbox. now the thing is trying to save it to a document like Mats.txt the thing is I want it to look something like this
Combobox Information on line 1 Texbox1 line 2 textbox2 line 3
[Code].....
It has to basically save to file all the text and numerical values. Then for the last line AUTO generate the text.
On my login form I have a username text box and a password text box...
The TxtUsername text box is preset with the following: Text: Username Colour: Gray
Here is the code for the TxtUsername (on click):
Private Sub TxtUsername_Click TxtUsername.Text = "" TxtUsername.ForeColor = Color.Black
(So it's like the facebook login if your familiar with it)When user clicks the text box, the gray text already inside gets erased and user is able to type with black text.The problem is that even when the user has typed in the box, every time you click the text box the text still gets erased....It's like the code should be something like If TxtUsername.Text = Anything but "Username" then dont change it to ""
I am having a problem with a entering sections of text into the same textbox without the other section of text disapearing. In other words, I have several buttons with strings attached to them. When the user presses one of the buttons the string does enter into the textbox. However, when the users presses another button the string from the first button disapears while the second string enters the textbox.
I am trying to copy the contents of a word document which is basically in a letter format.I am trying to copy it onto a rich text box editor...but when i copy it..i am losing all the formatting of the word document.This is the code i was using
Dim aDoc As Word.Document = WordApp.Documents.Open(outfile, missing, [readOnly], missing, missing, missing, missing, missing, missing, missing, missing, isVisible) aDoc.ActiveWindow.Selection.WholeStory()[code]......
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).
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.
I will show 3 columns of text in rich text box. i want show the column border with color.i can separate the texts with tabs or spaces but showing data in columns and cells will improve the visual of my program .
Okay, 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?
I 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.
Can I stop updating the user display of a control (rich text box) temporarily? I want it to process what I tell but not change how it looks for just a small piece of code.
I want to transfer data from one rich text box to another but when i use RichTextbox2.text = RichTextbox1.text it transfer just text not images.if there is any way to do so?
I have ~ 1 page how to that is currently in a text file which I want to add to a richtext box.I am just wondering if there is some way I can just copy/paste it so it keeps its formatting etc.
have more than one text color in the Rich Text Box, because when I highlight one word and use the color changer, it changes ALL of the words in the text box, and I want to know how to be able to have a specific word, or words, be a different color.
above code is working fine but when i retreive data from database in .rtf format & I try to protect some text then its not working in first time it works second time
what I am trying to do is create an effect in a richtextbox so when the user types any text surrounded by Brackets { } is coloured a different colour to the rest of the text say blue for example. How would I go about doing this?
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?
