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'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.

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 2 RepliesIs richtextbox can save a text within its control? What control in vb.net that could save the text being entered within its control paticularly, if any? I need somebody that could give me an idea on what control to use to save the text within the control. I'm not trying to save the text anywhere. I want to save it within the control. I don't have to save it with a filename and a path location. Just like this forum, which everytime you post and reply to a thread, you will have to enter your message in a certain workspace and after you submit, it will save within the control so everytime you open your thread you will see the messages. What control do I need to use in vb.net to do that?
View 1 RepliesI have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.
What I have so far:
If Val(txtEntered.Text) < 0 Or
(IsNumeric(txtEntered.Text) = False) Then
MsgBox("Sorry, but letters are not allowed!")

If the user does not follow this rule, I want them to get an error message.I have the calculations built and the error message, but not the constraint statement i.e. if users enter negative numbers the ouput is negative, which in the context of this app makes no sense. how a statement that would require the value entered into a text box to greater than a value.

I have this program I'm working on, and I was wondering if it was possible to disable/enable TextBoxes when specific words are wrtten. I tried doing this, but it errored. I'm a new programmer to VB, I just started a month ago, and I'm doing this for fun.
If TextBox1.Text = "Shutdown" then TextBox2.Enabled = True
I also want it so that you don't have to press a button to identify if it is the right text, so it could "scan" automatically.
I'm working on an application to write reports for the work I do. I have a Grid filled with Textboxes inside a Scrollviewer to input data for the report. I am using the arrow keys to navigate around the grid. The focus moves to the expected Textbox when the arrow keys are pressed but if I press any other key it is immediately followed by a Tab to the next Textbox. Even a Tab is followed by another Tab. Following is the code I use for the navigation.
Private Sub svReportPage_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles svReportPage.KeyUp
Dim focusDirection As FocusNavigationDirection
If e.Key = Key.Right Then focusDirection = FocusNavigationDirection.Right

I have a program in which a user enters a sentence in English into a text box, then the sentence is translated into French and German based on words in an array of structures that gets its values from a text file. I have almost all of the program written, but I am a bit confused on how to get VB to get the English words that are entered into the text box separately so they can be translated individually and the value returned. I need to use a Sub Procedure to get the English Words and to Translate them. [Code]
