I need help with my app. My app is retrieving data from the webBrowser and putting them into individual lines in the richtextbox. My problem is, if the retrieved string is too long then it takes more than 1 line in a richtextbox.

I was wondering if there is a way to modify the limit on the number of undo/redo actions a RichTextBox is capable of performing. It seems as though the limit is around 100, and I really need to increase this because of the demands of my application. I have text formatting (Bold, Underline, etc.) in my application, and since you can change the font of the text, I need to loop through the characters in the SelectedText one-by-one and apply the correct formatting to them in order to prevent any errors from appearing. Every time a single character is formatted, it counts as an action. As you can imagine, this quickly adds up and therefore makes my undo/redo features not as useful as I'd hope with the 100-action limit. Does anyone have any suggestions for me?

View 4 RepliesThe following code selects a line ina richtextbox. It works OK expect from one problem:
When a line is biger than the size of the richtextbox, it wraps it. This create a big problem as I can not select the last line of the richtextbox (when a line is wrapped it becomes two lines). When I set wordwrap to off it works just fine

View 1 RepliesTo read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal

how to delete a richtextbox line, if the line only has one value. Ex:
[Code]...
This is my first post at the forums, if I did something wrong making this topic Okey so here is the deal. The program task is to take 50 codes including letters and numbers. Take them and insert them into a webpage(webbrowser1) witch is designed to deal with these codes(3 fields). To check if the codes is valid etc.
Here is what I got :
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox1.Text)
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox2.Text) '
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox3.Text) '
What this does it takes textbox1.text input(first part of code) and inserts in the first field at the website.The to others to exactly the same.But instead of having 3 diffrent texboxes I want it like in this pic.

View 5 RepliesIf I set the Text property of a RTB to a string that has CrLf's in it, it seems the RTB reduces the CrLf's to a single character & screws up the positioning to set the SelectionStart property.So, for example, if I know the position of a character in the original string & I set the Selection Start value to that position, the selection highlighting will be off by 1 character if the start position is preceded by a CrLf & off by 2 characters if preceded by 2 CrLf's, etc.So how can I determine the correct position to specify my SelectionStart value?
View 2 RepliesFor the past 2-3 weeks, I've been on VB Express working on different word processors, working myself up from the level of the Windows Notepad to Wordpad, and eventually (hopefully) something as good as OpenOffice.org Writer or Microsoft Word.I'm currently stuck on something that I can't quite figure out. My question is basically this, "How do you add subscript and superscript characters (not just the few numbers in the character map) to a richtextbox control?!" I'd be very grateful to anyone who could provide me with some help in this area.
View 3 RepliesI have some code which displays data in a hexadecimal format, so each line of the display looks like this ...
000000 xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx cccccccccccccccc
... where the left six characters are an offset and each xx represents one character and the string of cs on the right are the actual characters.
I've learned that I have to keep control characters out of that string of cs or the display gets messed up. I've been using this code and it works fine (when it's not commented out). (binbuf is a Byte array)
'Select Case Convert.ToInt32(binbuf(i)) < 128
' Case True 'traditional ASCII character
