I know that the topic is kind of weird, but I will explain that here. I am reading text from a text box and inserting that into a listbox. I am wanting to read what the user inputs into the text box and add a character between each character they type. Here is what im wanting to do written out[code]...
View 4 RepliesI am reading a text file with mostly alpha characters. the content is not really relevant but the size of each line is very important. The process I will feed this text to will require each line be no more than 50 characters. So I will pre-process the text and add line feeds to make sure that happens.I tried several VB.NET regex like ^.*$ but that doesn't really break up the lines by 50 characters. I would take the result and iterate through each match and then cut it up and write it to an object in memory. Can this be done with a single regex pass?Otherwise I will use a streamreader and on each line check the length and if <=50 write it out with a streamwriter. if >50 cut it up in sections of 50 and then use streamwriter.
A brief example of my text:
119 SMITH KATY AAAA F ZZZ X NB SX ET
MILES,200/LM450

I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub
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 ?
View 3 RepliesEssentially 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 been trying to remove special characters. i am not able to remove many crlf in middile of the string.
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.
How do I limit the number of characters per each line of an RTB to 1 char per line? That is you type one character, after that the textbox should not accept further input on that specific line.-Knock knock -Who's there? -(looong pause..) Java
View 1 RepliesNot 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.
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 ?
View 4 RepliesI'm wondering is there a way to count the characters on a line like .length but with XML in VB. Take a look at my code and you'll probably understand exactly what im doing.Basically the formula is to count words by saying every 5 characters is a word. So I need to get the amount of characters in the line and divide by 5.[code]

I have a RTB which I import with a set of 7 or 9 didit numbers, 7 for Staff and 9 for Students. e.g. Staff numbers [code]and depending on what is selected in a list box ('Student' or 'Staff') will generate a string to create user accounts. To further error check I would like to check if a line in the RTB = 7 And Listbox = "Student" Then msgbox("Data mismatch between User ID and Account type")

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?

View 6 RepliesFor example I only the second character in each line to be an x, while the 3nd to 10th character must be a hex digit.At the moment I use a Select Case, then check the position of the caret (using textbox.selectionstart) and see if the key being pressed is a "legal" character.Is there a better way of doing this as it slows down on large amounts of text.

Select Case TextBox1.SelectionStart
