I'm trying to insert a - after ever 5 chars. I made this code.
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.Text.Length = "5" Then
TextBox1.Text += "-"
End If
[Code] .....
But the mouse returns always to the left after it enters a -.
I have a function that out puts letters or numbers like: S51AF36W562251DWD4DW
and what I want to do is in the same function after the string has been generated I want to
add some dashes in between the string so it looks like this: S51A - F36W - 5622 - 51DW - D4DW.
This should be so simple to do but I can't figure it out.. I've tried String.Replace, text.trim, etc.
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 have a form with four checkboxs and a textbox for an id number.I also have two tables in a database. The first has a column for the users Id, Name, and a column called Points.The second has a column for Id and one called Letters.What i want to do is, after the user enters the id number, and the user clicks checkboxA it should add a certain number, lets say 5, to the "points" cell for that id#(in the first database), and it should put the letter "a" in the "letters" column (of the second database) for that id number. Also, if a user deselects a checkbox it should remove the "a" from letters and subtract 5 from points.Also there will be different letters in the "letters" cell, so i cant just clear it, but i have to remove the specific letter.
View 13 RepliesWell I have been able to figure this out but what I want to do is make my string have a new line after 20 chars. I know how to find how many chars the string has but not how to insert environment.newline at 20 chars.I am using this to find the string length
If string.Length > 20 then
'Need to be able to insert environment.newline at 20 chars
Else
'Normal string
End If
I used to do this by eg String(52,95). (Getting 52 repetitions of an underscore) Cannot make out how to do it in dot net. I realise that String is no longer right but Str is not working either.
View 3 Repliesmy teacher assigns me to modify the program hangman game that allow a player to enter a word that contains any letters up to 10 letters.That assignment is from my textbook, Programming with MS Visual Basic 2010 by Diane Zak.[code]Now here's the problem I'm having trouble with. I don't know if my substrings is wrong or right, but when I type a word, the problem crashes and gives me the error of this.and another problem I'm having trouble with is how can I have dashes to match with the length of words? For example, if I type "game", it'll display "----" in the exe program. If I type "cat", it'll display "---" in the exe program as well.

View 3 RepliesI 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?

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.

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 ?

The line which is coloured red is the problem line. 'htmpath is shown as "C:UsersColinDocumentscwbrowser empsres.htm" which is correct.
Why I get the Illegal Characters In Path error.
So I have this

btw a changes everytime, so don't just say do b(0) = "H"
