Certain Characters In A Richtextbox?
Apr 10, 2012
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.

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.

If 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?

For 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.

I 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
' If Convert.ToChar(binbuf(i)) <> " "c Then

Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

I need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.

Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?

I'm making an application that will change position of two characters in Word.
[Code]...
Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time. Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?
