i am trying to restrict the input for a RichTextBox to certain values. I am trying to only allow Letters, the Backspace button and the Space button. The letters and backspace button work as expected but the Space button does not, i found the characters of the keyboard from this page but space is not working and it does not accept it,
View 1 Repliesim writing a program for counting the cash in a till.i have most of it worked out through research on this site and others. im trying to code a text box that allows the user to enter any amount between 0 and 9999.99. I have everything working except restricting user from entering more than 2 digits after the decimal. I could leave it as is and the currency format that im using will automatically round the input to 2 decimal places but this creates a problem if the user accidentally enters an extra digit and the program rounds up. for example if the user intends to enter "23.34" but accidentally enters "23.345" the program will round up to "$23.35" which will cause a problem in the end calculations.here is the code. if someone could explain what i need and where that would be great.

I am in a need of a Regular Expression to restrict input to only certain characters in a text box. The text box can only allow 0 or 1 "+" sign at the beginning and at no other position. The text box can only allow 0 or 1 ":" sign not before the "+" sign. The text box can allow any number of 0-9 digits.

I have some textboxes that I only want numbers in and only want a range of numbers to be valid. Also I do not want to use NUDs. I already have the textboxes connected to functons and subs so I do not really want to change them.How would I do this?
View 8 RepliesI am wanting to restrict the input on an InputBox and I am confused about how to do that. I know what to do on a text box to restrict input to numbers, the ".", and the backspace key, but I cannot figure out how to tie the input restrictions to the pop up InputBox. Do InputBox 's have an object name attached to them? Or are they just called InputBox.whatever?

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")
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.
View 2 RepliesI'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 6 RepliesIf I have a control, in this case a button, can I restrict the area it considers valid for text?
In the attached image, the left and right arrows are custom drawn in the paint even, I also have a scroll timer that scrolls the text if the length exceeds the buttons width as measured by Graphics.MeasureString.
I want to restrict the text from red line to red line so when the text scrolls it does not interfere with the arrow indicators, can the text area be overridden to some custom region?
I have alot of text boxes across alot of forms in ASP.NET programming in code behind pages in VB. I want to ensurethe user does not enter such characters as ' " ( ) or any which could mess up the sql syntax the script makes, and with some will validate what they entered is of numerical value.
Now I know you can stop the text box allowing such characters in a Windows application, but cannot find for the life of me a way of doing such in a web application - and its not really viable to perform a sub-string check at the click of a button for every box
I have a question, how would i have a button, then when you click it, it puts the text at the text cursor in the RTF?
View 5 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.
If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show.

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.

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?
View 3 RepliesIn my program, I have retrieved several lines of text in RichTextBox1.text. I need to get a
name(without the colon) using a keyword that is on the same line.[code...]
Lets say I set a keyword "vacation" and I need the code to get the name Sara that is in the same
line.I have seen some tutorials that retrieve left, middle, right that gets maybe the last two
letters in the string etc but I need it to get the Name without the colon.
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?
