How do I make this code for a multiline Textbox?
AllNumbers1.AddRange(CType(TabControl2.TabPages(2).Controls("txtIntDraw" & x), TextBox).Text.Split(CChar(",")))
This code wants to be transformed, txtIntDraw.Lines (i).
That's all the Code:
Try
'Throw everything into a list of String initially.
Dim AllNumbers1 As New List(Of String)
'Loop through each TextBox, splitting them by commas
For x = 1 To Val(txtXCount.Text)
AllNumbers1.AddRange(CType(TabControl2.TabPages(2).Controls("txtIntDraw" & x), TextBox).Text.Split(CChar(",")))
Next
'Remove non-integer entries.
AllNumbers1.RemoveAll(Function(x) Integer.TryParse(x, New Integer) = False)
'Join the distinct list to an array, then back to comma separated format into wherever you want it output.
OutputText1.Text = String.Join(",", AllNumbers1.Distinct().ToArray())
Dim part() As String = OutputText1.Text.Split(",")
Dim partCount As Integer = part.Length
TextBox6.Text = partCount
Array1()
Catch ex As Exception
End Try
Is it this simple? Instead of joining the distinct numbers with ",", use Environment.NewLine.
OutputText1.Text = String.Join(Environment.NewLine, AllNumbers1.Distinct())
But your code can be simplified into a method
Private Sub doStuff(delimitersIn As String(), delimiterOut As String)
Dim allNumbers As New List(Of Integer)()
For x = 1 To CInt(txtXCount.Text)
allNumbers.AddRange(TabControl2.TabPages(2).Controls("txtIntDraw" & x).Text.Split(delimitersIn, StringSplitOptions.RemoveEmptyEntries).Where(Function(s) Integer.TryParse(s, New Integer)).Select(Function(s) CInt(s)))
Next
Dim distinctNumbers = allNumbers.Distinct()
OutputText1.Text = String.Join(delimiterOut, distinctNumbers)
TextBox6.Text = distinctNumbers.Count().ToString()
End Sub
Call it with both delimiters
doStuff({Environment.NewLine, ","}, ",")
Or just the newline
doStuff({Environment.NewLine}, ",")

With this code, the information will be sent in several textboxes. I want to be sent only in the textbox line, with the name Textbox3.Lines(i), so I tried this code.
For i As Integer = 1 To 100
Dim firstBoxList = TxtIntDraws.Lines(i).Split(",").ToArray
Dim secondBoxList = TxtIntDraws.Lines(i + 1).Split(",").ToList()
Dim intersectionList = firstBoxList.Intersect(secondBoxList)
Dim Line = TxtIntDraws.Lines(i)
For Each str As String In intersectionList
Dim sb As New StringBuilder()
'inside the loop
sb.AppendLine(str & ",")
'and after the loop
'This will prevent the textbox from having to repaint on every iteration
TextBox3.Text = sb.ToString
Next
Next
This code does not work because it only shows a value, not all, practically resets and displays the last value found.
I don't think you need to add to the TextBox with each iteration. Just store all the strings as you iterate to 100, then update the TextBox at the end.
Dim intersectionList As New List(Of String)()
For i As Integer = 1 To 100
Dim firstBoxList = TxtIntDraws.Lines(i).Split(",")
Dim secondBoxList = TxtIntDraws.Lines(i + 1).Split(",")
intersectionList.Add(String.Join(", ", firstBoxList.Intersect(secondBoxList)))
Next
TextBox3.Text = String.Join(Environment.NewLine, intersectionList)
I want to compare the Textbox1 with TextBox2, or Textbox line 1 of the text box to the 2nd line, to show me the existing Character in another textbox, or show me how many characters are repeated. iI really like learning, so I would be helpful because I want to learn...
TextBox1.Text = 1,4,7,11,13,16,19,20,28,31,44,37,51,61,62,63,64,69,71,79,80
TextBox2.Text = 1,5,7,10,13,16,26,20,28,31,44,37,51,72,73,74,69,71,79,80
TextBox3.Text = Character Repeated: 1,7,13,16,20,28,31,44,37,51,69,71,79,80
TextBox4.Text = Number of Character Repeated = 14
TextBox5.Text = Number of Character which has not been repeated: 4,11,19,61,62,63,64 etc, you got to idea
TextBox6.Text = Number of Character isn't Repeated: 7
here are some codes: but I do not know how to apply them correctly.
Code 1: Show repetable character:
' Split string based on space
TextBox1.Text = System.IO.File.ReadAllText(Mydpi.Text)
TextBox2.Text = System.IO.File.ReadAllText(Mydpi.Text)
TextBox4.Text = System.IO.File.ReadAllText(Mydpi.Text)
For i As Integer = 0 To TextBox2.Lines.Count - 1
Dim textsrtring As String = TextBox4.Lines(i)
Dim words As String() = textsrtring.Split(New Char() {","c})
Dim found As Boolean = False
' Use For Each loop over words
Dim word As Integer
For Each word In words
TxtbValBeforeCompar.Text = TextBox1.Lines(i)
CompareNumbers()
If TextBox1.Lines(i).Contains(word) Then
found = True
Dim tempTextBox As TextBox = CType(Me.Controls("Checkertxt" & i.ToString), TextBox)
On Error Resume Next
If TextBox2.Lines(i).Contains(word) Then
If tempTextBox.Text.Contains(word) Then
Else
tempTextBox.Text = tempTextBox.Text + " " + TxtbValAfterCompar.Text()
End If
Else
End If
End If
Next
Next
Private Sub CompareNumbers()
'First Textbox that is to be used for compare
Dim textBox1Numbers As List(Of Integer) = GetNumbersFromTextLine(N1Check.Text)
'Second Textbox that is to be used for compare
Dim textBox2Numbers As List(Of Integer) = GetNumbersFromTextLine(TxtbValBeforeCompar.Text)
'Union List of Common Numbers (this uses a lambda expression, it can be done using two For Each loops instead.)
Dim commonNumbers As List(Of Integer) = textBox1Numbers.Where(Function(num) textBox2Numbers.Contains(num)).ToList()
'This is purely for testing to see if it worked you can.
Dim sb As StringBuilder = New StringBuilder()
For Each foundNum As Integer In commonNumbers
sb.Append(foundNum.ToString()).Append(" ")
TxtbValAfterCompar.Text = (sb.ToString())
Next
End Sub
Private Function GetNumbersFromTextLine(ByVal sTextLine As String) As List(Of Integer)
Dim numberList As List(Of Integer) = New List(Of Integer)()
Dim sSplitNumbers As String() = sTextLine.Split(" ")
For Each sNumber As String In sSplitNumbers
If IsNumeric(sNumber) Then
Dim iNum As Integer = CInt(sNumber)
TxtbValAfterCompar.Text = iNum
If Not numberList.Contains(iNum) Then
TxtbValAfterCompar.Text = ("")
numberList.Add(iNum)
End If

Code 2: Remove Duplicate Chars (Character)
Module Module1
Function RemoveDuplicateChars(ByVal value As String) As String
' This table stores characters we have encountered.
Dim table(value.Length) As Char
Dim tableLength As Integer = 0
' This is our result.
Dim result(value.Length) As Char
Dim resultLength As Integer = 0
For i As Integer = 0 To value.Length - 1
Dim current As Char = value(i)
Dim exists As Boolean = False
' Loop over all characters in the table of encountered chars.
For y As Integer = 0 To tableLength - 1
' See if we have already encountered this character.
If current = table(y) Then
' End the loop.
exists = True
y = tableLength
End If
Next
' If we have not encountered the character, add it.
If exists = False Then
' Add character to the table of encountered characters.
table(tableLength) = current
tableLength += 1
' Add character to our result string.
result(resultLength) = current
resultLength += 1
End If
Next
' Return the unique character string.
Return New String(result, 0, resultLength)
End Function
Sub Main()
' Test the method we wrote.
Dim test As String = "having a good day"
Dim result As String = RemoveDuplicateChars(test)
Console.WriteLine(result)
test = "areopagitica"
result = RemoveDuplicateChars(test)
Console.WriteLine(result)
End Sub
End Module
You could make use of some LINQ such as Intersect and Union.
Assuming your TextBox1 and TextBox2 contains the text you have provided.
Here's a simple method to find repeated and non repeated characters.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim firstBoxList = TextBox1.Text.Split(",").ToList()
Dim secondBoxList = TextBox2.Text.Split(",").ToList()
Dim intersectionList = firstBoxList.Intersect(secondBoxList)
For Each str As String In intersectionList
TextBox3.Text = TextBox3.Text & str & ","
Next
TextBox4.Text = intersectionList.Count()
Dim notRepeatedCharacter = firstBoxList.Union(secondBoxList).ToList
notRepeatedCharacter.RemoveAll(Function(x) intersectionList.Contains(x))
For each str As String In notRepeatedCharacter
TextBox5.Text = TextBox5.Text & str & ","
Next
TextBox6.Text = notRepeatedCharacter.Count()
End Sub
The output is something like that:
This consider both of the textboxes not repeated character.
If you just want to find the not repeated characters from first list to the second, this should do it:
firstBoxList.RemoveAll(Function(x) secondBoxList.Contains(x))
For Each str As String In firstBoxList
TextBox7.Text = TextBox7.Text & str & ","
Next
TextBox8.Text = firstBoxList.Count
And this is the output:
Here's the full code using String.Join to make the lists look smoother in the text boxes:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
'First we grab all the numbers written inside the textboxes (I am not verifying anything)
Dim firstBoxList = TextBox1.Text.Split(",").ToList()
Dim secondBoxList = TextBox2.Text.Split(",").ToList()
'Second we intersect the two lists and show them
Dim intersectionList = firstBoxList.Intersect(secondBoxList)
TextBox3.Text = String.Join(",", intersectionList)
TextBox4.Text = intersectionList.Count()
'We're checking the distintc character from both lists
Dim notRepeatedCharacter = firstBoxList.Union(secondBoxList).ToList
notRepeatedCharacter.RemoveAll(Function(x) intersectionList.Contains(x))
TextBox5.Text = String.Join(",", notRepeatedCharacter)
TextBox6.Text = notRepeatedCharacter.Count()
'we're checkng the distinct character inside first list that doesn't show in second list
firstBoxList.RemoveAll(Function(x) secondBoxList.Contains(x))
TextBox7.Text = String.Join(",", firstBoxList)
TextBox8.Text = firstBoxList.Count
End Sub
FASTER,WW0011,"CTR ,REURN,ALT TUBING HELIUM LEAK",DEFAULT test,1,3.81,test
I need to get the result of the following line as
Arr(0) =faster
Arr(1) =WW0011
Arr(2) =CTR ,REURN,ALT TUBING HELIUM LEAK
Arr(3) =DEFAULT test
Arr(4) =faster
Arr(5) = 1
Arr(6)=3.81
Arr(7) = test
I tried using split, but the problem is on Arr(2)
could anyone please give me a solution
You could use the TextFieldParser class which will take care of situations like this. Set the HasFieldEnclosedInQuotes property to true. Here is an example from MSDN (slightly altered):
Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("c:\logs\bigfile")
MyReader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited
MyReader.Delimiters = New String() {","}
'Set this to ignore commas in quoted fields.
MyReader.HasFieldsEnclosedInQuotes = True
Dim currentRow As String()
'Loop through all of the fields in the file.
'If any lines are corrupt, report an error and continue parsing.
While Not MyReader.EndOfData
Try
currentRow = MyReader.ReadFields()
' Include code here to handle the row.
Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException
MsgBox("Line " & ex.Message & " is invalid. Skipping")
End Try
End While
End Using
I use this function alot myself
Private Function splitQuoted(ByVal line As String, ByVal delimeter As Char) As String()
Dim list As New List(Of String)
Do While line.IndexOf(delimeter) <> -1
If line.StartsWith("""") Then
line = line.Substring(1)
Dim idx As Integer = line.IndexOf("""")
While line.IndexOf("""", idx) = line.IndexOf("""""", idx)
idx = line.IndexOf("""""", idx) + 2
End While
idx = line.IndexOf("""", idx)
list.Add(line.Substring(0, idx))
line = line.Substring(idx + 2)
Else
list.Add(line.Substring(0, Math.Max(line.IndexOf(delimeter), 0)))
line = line.Substring(line.IndexOf(delimeter) + 1)
End If
Loop
list.Add(line)
Return list.ToArray
End Function
Use a for loop to iterate the string char by char!
This code is supposed to output the number of times a word starts with a letter from the alphabet, but just displays zero for each one
I get no errors, but just a text file with all of the letters and zero for each one.
When pressing the debug button, it appears to do nothing. Here's the code
Imports System.IO
Module Module1
Sub Main()
Dim myArray As New List(Of String)
Using myReader As StreamReader = New StreamReader(".\myFile.txt")
'telling VB that we're using a StreamREader, read a line at a time
Dim myLine As String
myLine = myReader.ReadLine 'assigns the line to String Variable myLine
Do While (Not myLine Is Nothing)
myArray.Add(myLine) 'adding it to the list of words in the array
Console.WriteLine(myLine)
myLine = myReader.ReadLine
Loop
End Using
SortMyArray(myArray) 'Calls the new SubRoutine => SortMyArray, passing through the parameter myArray,
'created back on line 7 that stores all of the lines read from the text file.
'Console.ReadLine()
wordCount(myArray)
End Sub
Sub SortMyArray(ByVal mySort As List(Of String))
Dim Tmp As String, writePath As String = ".\sorted.txt"
Dim max As Integer = mySort.Count - 1
Dim myWriter As StreamWriter = New StreamWriter(writePath)
For Loop1 = 0 To max - 1
For Loop2 = Loop1 + 1 To max
If mySort(Loop1) > mySort(Loop2) Then
Tmp = mySort(Loop2)
mySort(Loop2) = mySort(Loop1)
mySort(Loop1) = Tmp
End If
Next
myWriter.WriteLine(mySort.Item(Loop1).ToString())
Next
myWriter.Dispose()
End Sub

Dim alphabet As String = "abcdefghijklmnopqrstuvwxyz", myString As String
Dim writePath As String = ".\counted.txt"
Dim myWriter As StreamWriter = New StreamWriter(writePath)
Dim countOf(25) As Integer, Max As Integer = stringArray.Count - 1
For Loop1 = 0 To 25
myString = alphabet.Substring(Loop1, 1)
For Loop2 = 0 To Max
If stringArray(Loop2).Substring(0, 1) = myString Then
countOf(Loop1) += 1
End If
Next
myWriter.WriteLine(myString & " occured " & countOf(Loop1) & " times ")

Any help would be appreciated. Thanks
How To get StartString And EndString
Dim startNumber As Integer
Dim endNumber As Integer
Dim i As Integer
startNumber = 1
endNumber = 4
For i = startNumber To endNumber
MsgBox(i)
Next i
Output: 1,2,3,4
I want mo make this like sample: startString AAA endString AAD
and the output is AAA, AAB, AAC, AAD
This is a simple function that should be easy to understand and use. Every time you call it, it just increments the string by one value. Just be careful to check the values in the text boxes or you can have an endless loop on your hands.
Function AddOneChar(Str As String) As String
AddOneChar = ""
Str = StrReverse(Str)
Dim CharSet As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
Dim Done As Boolean = False
For Each Ltr In Str
If Not Done Then
If InStr(CharSet, Ltr) = CharSet.Length Then
Ltr = CharSet(0)
Else
Ltr = CharSet(InStr(CharSet, Ltr))
Done = True
End If
End If
AddOneChar = Ltr & AddOneChar
Next
If Not Done Then
AddOneChar = CharSet(0) & AddOneChar
End If
End Function
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim S = TextBox1.Text
Do Until S = TextBox2.Text
S = AddOneChar(S)
MsgBox(S)
Loop
End Sub
This works as a way to all the codes given an arbitrary alphabet:
Public Function Generate(starting As String, ending As String, alphabet As String) As IEnumerable(Of String)
Dim increment As Func(Of String, String) = _
Function(x)
Dim f As Func(Of IEnumerable(Of Char), IEnumerable(Of Char)) = Nothing
f = _
Function(cs)
If cs.Any() Then
Dim first = cs.First()
Dim rest = cs.Skip(1)
If first = alphabet.Last() Then
rest = f(rest)
first = alphabet(0)
Else
first = alphabet(alphabet.IndexOf(first) + 1)
End If
Return Enumerable.Repeat(first, 1).Concat(rest)
Else
Return Enumerable.Empty(Of Char)()
End If
End Function
Return New String(f(x.ToCharArray().Reverse()).Reverse().ToArray())
End Function
Dim results = New List(Of String)
Dim text = starting
While True
results.Add(text)
If text = ending Then
Exit While
End If
text = increment(text)
End While
Return results
End Function
I used it like this to produce the required result:
Dim alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
Dim results = Generate("S30AB", "S30B1", alphabet)
This gave me 63 values:
S30AB
S30AC
...
S30BY
S30BZ
S30B0
S30B1
It should now be very easy to modify the alphabet as needed and to use the results.
One option would be to put those String values into an array and then use i as an index into that array to get one element each iteration. If you do that though, keep in mind that array indexes start at 0.
You can also use a For Each loop to access each element of the array without the need for an index.
if the default first two string value of your output is AA.
You can have a case or if-else conditioning statement :
and then set 1 == A 2 == B...
the just add or concatenate your default two string and result string of your case.
I have tried to understand that you are looking for a series using range between 2 textboxes. Here is the code which will take the series and will give the output as required.
Dim startingStr As String = Mid(TextBox1.Text, TextBox1.Text.Length, 1)
Dim endStr As String = Mid(TextBox2.Text, TextBox2.Text.Length, 1)
Dim outputstr As String = String.Empty
Dim startNumber As Integer
Dim endNumber As Integer
startNumber = Asc(startingStr)
endNumber = Asc(endStr)
Dim TempStr As String = Mid(TextBox1.Text, 1, TextBox1.Text.Length - 1)
Dim i As Integer
For i = startNumber To endNumber
outputstr = outputstr + ", " + TempStr + Chr(i)
Next i
MsgBox(outputstr)
The First two lines will take out the Last Character of the String in the text box.
So in your case it will get A and D respectively
Then outputstr to create the series which we will use in the loop
StartNumber and EndNumber will be give the Ascii values for the character we fetched.
TempStr to Store the string which is left off of the series string like in our case AAA - AAD Tempstr will have AA
then the simple loop to get all the items fixed and show
in your case to achive goal you may do something like this
Dim S() As String = {"AAA", "AAB", "AAC", "AAD"}
For Each el In S
MsgBox(el.ToString)
Next
FIX FOR PREVIOUS ISSUE
Dim s1 As String = "AAA"
Dim s2 As String = "AAZ"
Dim Last As String = s1.Last
Dim LastS2 As String = s2.Last
Dim StartBase As String = s1.Substring(0, 2)
Dim result As String = String.Empty
For I As Integer = Asc(s1.Last) To Asc(s2.Last)
Dim zz As String = StartBase & Chr(I)
result += zz & vbCrLf
zz = Nothing
MsgBox(result)
Next
**UPDATE CODE VERSION**
Dim BARCODEBASE As String = "SBA0021"
Dim BarCode1 As String = "SBA0021AA1"
Dim BarCode2 As String = "SBA0021CD9"
'return AA1
Dim FirstBarCodeSuffix As String = Replace(BarCode1, BARCODEBASE, "")
'return CD9
Dim SecondBarCodeSuffix As String = Replace(BarCode2, BARCODEBASE, "")
Dim InternalSecondBarCodeSuffix = SecondBarCodeSuffix.Substring(1, 1)
Dim IsTaskCompleted As Boolean = False
For First As Integer = Asc(FirstBarCodeSuffix.First) To Asc(SecondBarCodeSuffix)
If IsTaskCompleted = True Then Exit For
For Second As Integer = Asc(FirstBarCodeSuffix.First) To Asc(InternalSecondBarCodeSuffix)
For Third As Integer = 1 To 9
Dim tmp = Chr(First) & Chr(Second) & Third
Console.WriteLine(BARCODEBASE & tmp)
If tmp = SecondBarCodeSuffix Then
IsTaskCompleted = True
End If
Next
Next
Next
Console.WriteLine("Completed")
Console.Read()
Take a look into this check it and let me know if it can help
