Is it possible to replace string characters using the delimiter and limit of a split function?
For example you have this string "1,1,1,1,1"
I wish to replace sentence number 2 into the string "2" between the "," character so that will be limit number 1.
So the result would be "1,2,1,1,1".
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

I'm trying to make a function in VB.net that will loop through an algorithm. I've split the algorithm into an array using the Split command, so I have an array with the values. I then try to loop through them and replace a # with "Number" where necessary, however VB.net throws an error. Algorithms are in the format A B C D E F 1 2 3 #
Function generate(ByVal alg As String)
Dim algSplit As String() = alg.Split(" ")
For Each digit In algSplit

View 3 RepliesWhile my user is typing text into a textbox i want the characters " to be replaced with ' '. The thing is, when i put ' ' in the replace code, it thinks it is a comment so i cannot run the code without producing an error.Also in my multitext box, everytime i write text and hit ENTER, save and then load it back again, the last line ends with a comma, so:
Line 1
Line 2,
When the text is written to the file i read from, it will show like this:
"Line 1Line 2",
So i need a way of trimming ", when the apostrophe " and the comma , are together. My code already trims "".

View 8 RepliesI'm using the Oracle command dbms_output.get_line to retrieve output from a stored procedure. Once my code runs the command, I'm retrieving the results through a buffer string, 32000 bytes long.Inevitably, this string will have Oracle line breaks (chr(10) and chr(13)) in it that I'd like to replace with Environment.NewLine so I can display the output in a standard Winforms textbox.Here is the code I've been using - I don't recall exactly where I got the Oracle command right now, but if I find it, I'll add the link.

my OCR copy text to a TextBox with at end, acts like enter key. Is it possible to replace it to something or remove it? For example, I want to copy number 1000 to my text box with OCR but I get 1000(its a little different boxes, I couldnt copy exact ones here). And I cant do
TextBox2.Text = TextBox2.Text.Replace("", "")
, because is an "enter key" and what I get looks like that:
My program paste lots of stuff to a text box. Is it possible to replace every character that is not a number or a point to nothing? It may get lots of weird character there so is here way to replace them to οΏ½οΏ½ and keeping numbers?
I know how to TextBox1.Text = TextBox1.Text.Replace("%", "") But its too many simbols to list, Can it be done easier?
I am trying to do this but it doesn't work:
VB
Dim str As String = "07" & GetBetween("Stephen 0761234567", "07", vbNewLine)Dim op As String = "lol" TextBox1.Text.Replace(str, op)
GetBetween is just a function to match something between something else. That works fine, the string (str) sets as 0761234567 just like I want but when i try to replace the text it doesn't work.
I'll explain the scenario. I have a list containing character list and it's corresponding unicode characters(copied from CharMap and pasted in VB editor).

I have a program where a user enters a list of numbers in the form of a string. This list of numbers is always a multiple of 8.So the list can contain 8, 16, 32, 40, 48, etc. numbers.
I need to split that string into every 8 characters.For example, say the user entered "1234123445674567"
How can I split it into a string array where (0) is "12341234" and (1) is "45674567"
Note: The size of the array has to be equal to the length of the string divided by 8.
Like this:
Dim stringArray(txtInput.Text.Length/8) as String Edit: I know I could do this by making a loop that counts 8 numbers and splits it into an array but that would be lengthy and take a few variables and I know there's a more efficient way to do it. I just don't know the syntax.
MVC 3. Vb.net. Part of my app generates PDF files using Itextsharp. Some strings are too long to go onto the background image correctly. So I basically need to split this string when its over 26 characters long and when it splits it cant split in the middle of a word. from there I will use newline to add the string to the right to the next line... I did start bulding the function that I will pass the string into test for length and then pass back the string after it finishes.
Private Function stringLength(ByVal _string As String) As String
If _string.Length < 26 Then
_string.Split(
End If
End Function

I thought about how the String.Split method works.
Often I have wanted to split a string on the characters that terminate a sentence such as a full stop >> . << ,
a question mark >> ? << or an exclamation mark >> ! << and still keep the string split characters.
[Code]....
Basically, for each character in a charArray created from the string to split, if the character is a letter, digit, or hyphen, I append it to a temporary string. When I see a split character or the last character, and the temporary string has value, I add it to the collection to return.
For i As Integer = 0 To (charArrayLength - 1)
charToInspect = CChar(charArray.GetValue(i))
If IsLetterOrDigit(charToInspect) Or charToInspect = hyphen Then

I am working on a site where I use the Split function on a string. To make sure I used a separator character that I do not use anywhere in the data I selected the character'£'. This worked fine in Firefox and Safari, but in IE8 I get an 'Index out of range' error, so apparently the '£' character is not handled correctly.
View 5 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.

I am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.
View 5 RepliesI would like to create a split container with a three way split. The first split is a vertical split. The second is creating a horizontal split within panel2 of the first split container. panel1 will hold a treeview control the other two panels will hold listview controls
I think this question has been asked already in a couple different ways and I've reviewed those posts and I've tried to do what was suggested but it doesn't seem to work for me. I've tried to place a second split container inside panel2 of the first split containter. This gave me what appeared to be a three way vertical split.
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.

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!

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.
