I am trying to output text into another text box once the first has 5 entries in it. Example; i give the scores 100,200,300,200,200. Now when I try to enter a new score it should place it in the next textbox, but doesent.
Dim Testint As Integer ' define an Integer for testing
Dim sampleTextBox(3) As TextBox
sampleTextBox(0) = txtPlayer1Scores
sampleTextBox(1) = txtPlayer2Scores
sampleTextBox(2) = txtPlayer3Scores
sampleTextBox(3) = txtPlayer4Scores
Dim sampleLabel(3) As Label
sampleLabel(0) = lblPlayer1Average
sampleLabel(1) = lblPlayer2Average
sampleLabel(2) = lblPlayer3Average
sampleLabel(3) = lblPlayer4Average
scoreArray(textCount, gameNumber - 1) = CInt(txtScoreInput.Text) ' subtracting 1 from the score array
sampleTextBox(textCount).Text &= " Score:" & scoreArray(textCount, gameNumber - 1) & vbCrLf
'output statement
gameNumber = gameNumber + 1 'increment the counter
If gameNumber > MAX_SCORE_LENGTH Then
sampleTextBox(textCount).Focus()
sampleTextBox(textCount).Enabled = False
For i As Integer = 0 To 4 'Add the array values up
scoreTotal += scoreArray(textCount, i)
Next
playerAverage = scoreTotal / MAX_SCORE_LENGTH
sampleLabel(labelCount).Text = playerAverage
' I need the textbox switch here
textCount = textCount + 1
labelCount = labelCount + 1 ' and labels
ElseIf textCount > MAX_PLAYERS Then
'calculate team average
btnEnterScore.Enabled = False
Else
lblEnterScore.Text = "Enter Score for game #" & gameNumber ' 5 scores have not be inputted,
txtScoreInput.Text = "" 'ask for more
txtScoreInput.Focus() 'refocus the input textbox
End If
Fixed it...setting the max length to 15 forces it to move on after 15 digits, it also works when there are less than 15 digits
txtscore1.MaxLength = 15

I'm doing a school project in Visual Basic (using visual studio 2015) and i'm kinda stuck.
My goal is to create a lottery, where player chooses 6 numbers from checkboxes, then he generates six random numbers (1 - 49) and finally, those two sets should be compared and needed result is the number of correctly guessed numbers.
I have both results (guessed numbers, generated numbers) saved in two different labels.
The checkboxes itself are genereted like this:
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
lev = 20
tt = 0
For j = 1 To 50
tt = tt + 1
n = n + 1
box(j) = New CheckBox
box(j).Name = "box(" & Str(j) & ")"
If n = 11 Then lev = lev + 110 : n = 1 : tt = 1
box(j).Left = lev
box(j).Parent = Me
box(j).Top = tt * 20
box(j).Tag = j
box(j).Text = j
box(j).Visible = True
Next
box(50).Enabled = False
End Sub
First label (guessed numbers) is filled this way (i'm not posting whole code)
For j = 1 To 50
If box(j).Checked = True Then Label9.Text = Label9.Text + " " + box(j).Text
Next
and the second one (generated numbers) like this:
Do
rn = rg.Next(1, 50)
If Not r.Contains(rn) Then
r.Add(rn)
End If
Loop Until r.Count = 6
Label1.Text = r(0).ToString + " " + r(1).ToString + " " + r(2).ToString + " " + r(3).ToString + " " + r(4).ToString + " " + r(5).ToString
any idea how to compare numbers stored in those labels and get the result (number of correctly guessed numbers).
thanks in advance
You can compare numbers in the labels by splitting the Text properties of the labels into arrays of strings and converting them to integer arrays. First though there is a tiny problem with your code that adds the guessed numbers to the label.
For j = 1 To 50
If box(j).Checked = True Then Label9.Text = Label9.Text + " " + box(j).Text
Next
The " " should be moved to the end of the line because at the moment, the label will always start with a space and that messes with the function below. So you should have -
For j = 1 To 50
If box(j).Checked = True Then Label9.Text = Label9.Text + box(j).Text + " "
Next
Ok. The function below splits the two text labels into their own array and loops through the guesses and checks if any number is contained in the generated numbers. It then returns the number of matches.
Private Function ComparePicks() As Integer
Dim numbersMatched As Integer
Dim picks(5) As Integer
Dim generatedNumbers(5) As Integer
For i As Integer = 0 To 5
picks(i) = CInt(Split(Label9.Text, " "c)(i))
Next
For i As Integer = 0 To 5
generatedNumbers(i) = CInt(Split(Label1.Text, " "c)(i))
Next
For i As Integer = 0 To 5
If generatedNumbers.Contains(picks(i)) Then
numbersMatched += 1
End If
Next
Return numbersMatched
End Function
I'm currently having a slight issue duplicating a row and incrementing the sequence number.
So based on a button click, this is how I'm duplicating row 0, duplicated only one time per click.
Dim dr As DataRow
For n As Integer = 0 To 0 ' how many dupes you want
dr = tbl.NewRow
For c As Integer = 0 To tbl.Columns.Count - 1 ' copy data from 0 to NewRow
dr.Item(c) = tbl.Rows(0).Item(c)
Next
tbl.Rows.Add(dr) ' add NewRow to datatable
Next n
Here's how I'm creating the sequence number, pads with leading zeros, which seems to increment, but only after I click the duplicate button, so essentially the last row added, it the duplicated row 0, but doesn't represent the new sequence number needed.
'UPDATE SEQUENCE NUMBER
i += 1
Dim value As Integer = i
Dim r As Integer
Dim decimalLength1 As Integer = value.ToString("D").Length + 7
Dim decimalLength2 As Integer = value.ToString("D").Length + 6
Dim decimalLength3 As Integer = value.ToString("D").Length + 5
Dim decimalLength4 As Integer = value.ToString("D").Length + 4
If i >= 0 And i <= 9 Then
'1 TO 9 FORMAT
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells("sequence")
DataGridView1.Item(73, r).Value = value.ToString("D" + decimalLength1.ToString())
'Debug.Print(value.ToString("D" + decimalLength1.ToString()))
ElseIf i >= 10 And i <= 99 Then
'10 TO 99 FORMAT
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells("sequence")
DataGridView1.Item(73, r).Value = value.ToString("D" + decimalLength2.ToString())
'Debug.Print(value.ToString("D" + decimalLength1.ToString()))
ElseIf i >= 100 And i <= 999 Then
'100 TO 999 FORMAT
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells("sequence")
DataGridView1.Item(73, r).Value = value.ToString("D" + decimalLength3.ToString())
'Debug.Print(value.ToString("D" + decimalLength1.ToString()))
ElseIf i >= 1000 And i <= 9999 Then
'1000 TO 9999 FORMAT
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells("sequence")
DataGridView1.Item(73, r).Value = value.ToString("D" + decimalLength4.ToString())
'Debug.Print(value.ToString("D" + decimalLength1.ToString()))
End If
Row 0 will always have a sequence number of 1, so in theory I need to start incrementing at 2.
Suggestions? Is there a better/cleaner way of doing this?
UPDATE 2
Dim startSeq As Integer = Convert.ToInt32(tbl.Rows(0).Item(73))
MsgBox("startSeq = " & startSeq)
For n As Integer = 0 To NumericUpDown1.Value - 1
MsgBox("n = " & n)
dr = tbl.NewRow
For c As Integer = 0 To tbl.Columns.Count - 1
dr.Item(c) = tbl.Rows(0).Item(c)
If c = "73" Then ' if this is the SEQ column,
' add the current seq val to the seq column
dr.Item(c) = (startSeq + n).ToString("00000000")
End If
Next c
tbl.Rows.Add(dr)
Next n
It seems like you should be able to add the sequencer as you create the duplicates. Perhaps make it a method and pass the index of the column which has the sequence string. Something like:
Private Sub DuplicateRows(ColIndx As Integer,
Dupes As Integer)
' start value is Row(0) + 1
Dim startSeq As Integer = Convert.ToInt32(tbl.Rows(0).Item(ColIndx )) + 1
For n As Integer = 0 to Dupes -1
dr = tbl.NewRow
For c As Integer = 0 To tbl.Columns.Count - 1
If c = ColIndx Then ' if this is the SEQ column,
' add the current seq val to the seq column
dr.Item(c) = (startSeq + n).ToString("00000000")
Else
' otherwise copy the data from Row(0)
dr.Item(c) = tbl.Rows(0).Item(c)
End If
Next c
tbl.Rows.Add(dr)
Next n
End Sub
This should initialize each new row with an incremented counter. Is there a better/cleaner way of doing this
a) you should be adding to the DataTable, not the DGV if it is bound
b) (startSeq + n).ToString("00000000") should work to do the padding etc instead of that ugly block of code.
c) Use Option Strict On. If c = "73" ... is nonsense which makes the compiler guess at your intentions. Its is bug food.
d) Hardcoding "73" may work this time, but previously you said it could be anywhere. The code below finds the sequence column based on the name so it can appear anywhere. Rather than a form level var, you could find it just before you make the dupes or even in the Dupes procedure.
e) Dim startSeq As Integer = Convert.ToInt32(tbl.Rows(0).Item(73)) if you examine the answer above, this should be ... + 1 to increment the first value.
Usage:
Private tbl As DataTable ' table loaded from flat file
Private SeqColIndex As Integer ' assigned somewhere to
' point to the "sequence" column
' method to load data
Dim connstr = "Provider=Microsoft.ACE.OLEDB.12.0;..."
Using cn As New OleDbConnection(connstr)
...
End Using
' FIND the sequence column for this session
For n = 0 To tbl.Columns.Count - 1
If tbl.Columns(n).ColumnName.ToLowerInvariant = "sequence" Then
SeqColIndex = n
Exit For
End If
Next
' later to add some rows
Private Sub ButtonAddRow_Click(...
DuplicateRows(SeqColIndex, NumericUpDown1.Value)
End Sub
I have used below code to find average of 10 sample . But during first time it take sample and do the averaging . during next cycle counter not become Zero.and text box not updating
Static counter As Integer = 0
DIm average_sum As Double = 0
If counter < 10 Then
counter = counter + 1
Count_val.Text = counter
Dim array(10) As Double
For value As Integer = 0 To counter
array(counter) = k
average_sum = average_sum + array(counter)
Next
If counter = 10 Then
average_sum = average_sum / array.Count
System.Threading.Thread.Sleep(250)
Array_count.Text = average_sum
End If
If counter > 10 Then
average_sum = 0
counter = 0
End If
End If
If Avg_count < 10 Then
Dim array(10) As Double
For value As Double = 0 To Avg_count
array(Avg_count) = k
average_sum = average_sum + array(Avg_count)
Avg_count = Avg_count + 1
Next
If Avg_count = 10 Then
average_sum = average_sum / Avg_count
System.Threading.Thread.Sleep(250)
Average.Text = average_sum
Avg_count = 0
End If
End If
Here count value setting properly . But after 2 to3 cycle Average will done earlier itself same thing i writen in excel to compare averages but not matching with average and excel sheet data
Below is excel sheet code.Both code are in timer1 block.
If counter < 10 Then
'counter = 0
'average_sum = 0

I'm making an app with a color dropper tool on it using g.CopyFromScreen(screenpoint, Point.Empty, Bmp2.Size) (the dropper tool works currently), once I have the dropper values I want to convert the RBG values into individual integers.
The values that i'm converting are in this format
Color [A=255, R=240, G=240, B=240]
which needs to be in four different integers
My code is giving me odd results and I'm lost now
My code:
Dim text1Conv As String
text1Conv = TextBox1.Text
Dim myChars() As Char = text1Conv.ToCharArray()
For Each ch As Char In myChars
If Char.IsDigit(ch) And Not ch = " " And Not ch = "," And Not count > 2 Then
color1Conv = color1Conv + ch
TextBox2.Text = TextBox2.Text + color1Conv 'test result
count = count + 1
ElseIf Char.IsDigit(ch) And Not ch = " " And Not ch = "," And count < 2 And Not count > 5 Then
color2Conv = color2Conv + ch
TextBox2.Text = TextBox2.Text + color2Conv 'test result
count = count + 1
ElseIf Char.IsDigit(ch) And Not ch = " " And Not ch = "," And count < 5 And Not count > 8 Then
color3Conv = color3Conv + ch
TextBox2.Text = TextBox2.Text + color3Conv 'test result
count = count + 1
ElseIf Char.IsDigit(ch) And Not ch = " " And Not ch = "," And count < 8 And Not count > 11 Then
color4Conv = color4Conv + ch
TextBox2.Text = TextBox2.Text + color4Conv 'test result
count = count + 1
End If
Next
results: 225 255 118 112 122
results: 225 255 116 772 721
probably an easy one but I can't see it
Using regular expressions:
I used "[A=255, R=241, G=24, B=2]" as a test string and split it into four integers.
Dim a as Integer, r as Integer, g as Integer, b as Integer
Dim s as String = "[A=255, R=241, G=24, B=2]"
Dim mc as MatchCollection = System.Text.RegularExpressions.Regex.Matches( s, "(\d+)\D+(\d+)\D+(\d+)\D+(\d+)\D+", RegexOptions.None )
Integer.TryParse( mc(0).Groups(1).Value, a )
Integer.TryParse( mc(0).Groups(2).Value, r )
Integer.TryParse( mc(0).Groups(3).Value, g )
Integer.TryParse( mc(0).Groups(4).Value, b )
NOTE: it will have no problems with numbers being 1, 2, or any number of digits long.
You can use regular expressions:
Imports System.Text.RegularExpressions
Dim input As String = "Color [A=255, R=240, G=240, B=240]"
Dim re As New Regex("Color \[A=(\d+), R=(\d+), G=(\d+), B=(\d+)\]")
Dim m As Match = re.Match(input)
Dim integer1 As Integer = Convert.ToInt32(m.Groups(1).Value) '255
Dim integer2 As Integer = Convert.ToInt32(m.Groups(2).Value) '240
Dim integer3 As Integer = Convert.ToInt32(m.Groups(3).Value) '240
Dim integer4 As Integer = Convert.ToInt32(m.Groups(4).Value) '240
I have a textbox on a form where the user types some text. Each letter is assigned a different value like a = 1, b = 2, c = 3 and so forth. For example, if the user types "aa bb ccc" the output on a label should be like:
aa = 2
bb = 4
dd = 6
Total value is (12)
I was able to get the total value by looping through the textbox string, but how do I display the total for each word. This is what I have so far:
For letter_counter = 1 To word_length
letter = Mid(txtBox1.Text, letter_counter, 1)
If letter.ToUpper = "A" Then
letter_value = 1
End If
If letter.ToUpper = "B" Then
letter_value = 2
End If
If letter.ToUpper = "C" Then
letter_value = 3
End If
If letter.ToUpper = "D" Then
letter_value = 4
End If
If letter.ToUpper = "E" Then
letter_value = 5
End If
If letter.ToUpper = " " Then
letter_value = 0
End If
totalletter = totalletter + letter_value
Label1.Text = Label1.Text & letter_value & " "
txtBox2.Text = txtBox2.Text & letter_value & " "
Next letter_counter
This simple little routine should do the trick:
Private Sub CountLetters(Input As String)
Label1.Text = ""
Dim total As Integer = 0
Dim dicLetters As New Dictionary(Of Char, Integer)
dicLetters.Add("a"c, 1)
dicLetters.Add("b"c, 5)
dicLetters.Add("c"c, 7)
For Each word As String In Input.Split
Dim wordtotal As Integer = 0
For Each c As Char In word
wordtotal += dicLetters(Char.ToLower(c))
Next
total += wordtotal
'Display word totals here
Label1.Text += word.PadRight(12) + "=" + wordtotal.ToString.PadLeft(5) + vbNewLine
Next
'Display total here
Label1.Text += "Total".PadRight(12) + "=" + total.ToString.PadLeft(5)
End Sub
This should give you an idea:
Dim listOfWordValues As New List(Of Integer)
For letter_counter = 1 To word_length
letter = Mid(txtBox1.Text, letter_counter, 1)
If letter = " " Then
totalletter= totalletter + letter_value
listOfWordValues.Add(letter_value)
letter_value = 0
Else
letter_value += Asc(letter.ToUpper) - 64
End If
Next letter_counter
totalletter = totalletter + letter_value
If Not txtBox1.Text.EndsWith(" ") Then listOfWordValues.Add(letter_value)
txtBox2.Text = txtBox2.Text & string.Join(", ", listOFWordValues);
You can try something like this. Assuming txtBox1 is the string the user enters and " " (space) is the word delimiter:
Dim words As String() = txtBox1.Text.Split(New Char() {" "}, StringSplitOptions.RemoveEmptyEntries)
Dim totalValue As Integer = 0
Dim wordValue As Integer = 0
For Each word As String In words
wordValue = 0
For letter_counter = 1 To word.Length
Dim letter As String = Mid(txtBox1.Text, letter_counter, 1)
Select letter.ToUpper()
Case "A":
wordValue = wordValue + 1
Case "B":
wordValue = wordValue + 2
' And so on
End Select
Next
totalValue = toalValue + wordValue
Next
The above code first takes the entered text from the user and splits it on " " (space).
Next it sets two variables - one for the total value and one for the individual word values, and initializes them to 0.
The outer loop goes through each word in the array from the Split performed on the user entered text. At the start of this loop, it resets the wordValue counter to 0.
The inner loop goes through the current word, and totals up the values of the letter via a Select statement.
Once the inner loop exits, the total value for that word is added to the running totalValue, and the next word is evaluated.
At the end of these two loops you will have calculated the values for each word as well as the total for all the worlds.
The only thing not included in my sample is updating your label(s).
Try this ..
Dim s As String = TextBox1.Text
Dim c As String = "ABCDE"
Dim s0 As String
Dim totalletter As Integer
For x As Integer = 0 To s.Length - 1
s0 = s.Substring(x, 1).ToUpper
If c.Contains(s0) Then
totalletter += c.IndexOf(s0) + 1
End If
Next
MsgBox(totalletter)
I would solve this problem using a dictionary that maps each letter to a number.
Private Shared ReadOnly LetterValues As Dictionary(Of Char, Integer) = GetValues()
Private Shared Function GetValues() As IEnumerable(Of KeyValuePair(Of Char, Integer))
Dim values As New Dictionary(Of Char, Integer)
Dim value As Integer = 0
For Each letter As Char In "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
value += 1
values.Add(letter, value)
Next
Return values
End Function
Public Function CalculateValue(input As String) As Integer
Dim sum As Integer = 0
For Each letter As Char In input.ToUpperInvariant()
If LetterValues.ContainsKey(letter) Then
sum += LetterValues.Item(letter)
End If
Next
Return sum
End Function
Usage example:
Dim sum As Integer = 0
For Each segment As String In "aa bb ccc".Split()
Dim value = CalculateValue(segment)
Console.WriteLine("{0} = {1}", segment, value)
sum += value
Next
Console.WriteLine("Total value is {0}", sum)
' Output
' aa = 2
' bb = 4
' ccc = 9
' Total value is 15
