vb.net code reads lables wrong - vb.net

Okay, so I am making a game, like cookie clicker, or in my case - http://www.silvergames.com/poop-clicker (don't ask...), so that when you click on the icon in the center, it changes the total value by adding 1. On the side, you have a picture which you click to increase the amount it generates automatically every second.
At the moment I have it like this:
The timer tics every second. If the total amount > the cost of upgrade then it shows the picture of the thing you click to upgrade.
When you click that picture -
The cost is taken away from the total amount.
It changes the amount of times you have used that upgrade by +1.
The automatic upgrades per second is changed by +1.
The Cost is increased by 10.
What is happening is that I click the icon in the middle say 5 times (very quickly) and it only comes up with a total of 3. That in itself is a problem, but the even worse problem is that it shows the picture to click, when i told it to only show when the total value was > 10 (the cost of the upgrade).
I am really confused, and any help will be much appreciated.
Thanks

PS. Here's the Code -
Public Class Form1
Private Sub picPoop_Click(sender As Object, e As EventArgs) Handles picPoop.Click
lblPoops.Text = lblPoops.Text + 1
End Sub
Private Sub picCursor_Click(sender As Object, e As EventArgs) Handles picCursor.Click
lblPoops.Text = lblPoops.Text - lblCursorCost.Text
lblCursorAmmount.Text = lblCursorAmmount.Text + 1
lblPoopsPerSec.Text = lblPoopsPerSec.Text + 1
lblCursorCost.Text = lblCursorCost.Text + 10
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
lblCursorAmmount.Text = 0
lblCursorCost.Text = 10
lblBabyAmmount.Text = 0
lblBabyCost.Text = 100
lblBowlAmmount.Text = 0
picCursor.Hide()
tmrSec.Start()
End Sub
Private Sub tmrSec_Tick(sender As Object, e As EventArgs) Handles tmrSec.Tick
If lblPoops.Text > lblCursorCost.Text Then picCursor.Show()
End Sub
End Class
Again, don't ask where this ridiculous idea came from, I can assure you it wasn't mine.

Your main problem with this is that in your Timer sub, you are comparing text to text. In this case, a value of "3" > "21", since text comparisons work on a char by char basis. When this happens, your pictureBox is being shown. As others suggested, you can use any of the string to numeric conversion functions in your timer event to make this work better.
A slightly better approach would be to declare some class level numeric variables that hold each individual value and displays them when needed. As an example
numPoops += 1
lblPoops.Text = numPoops
This will make sure that all math will work correctly.

You are dealing with the Value of the textboxes, not the Text in it.
You should enclose each textbox with VAL() to get its exact value as a number.
Private Sub picPoop_Click(sender As Object, e As EventArgs) Handles picPoop.Click
lblPoops.Text = VAL(lblPoops.Text) + 1
End Sub
Private Sub picCursor_Click(sender As Object, e As EventArgs) Handles picCursor.Click
lblPoops.Text = VAL(lblPoops.Text) - VAL(lblCursorCost.Text)
lblCursorAmmount.Text = VAL(lblCursorAmmount.Text) + 1
lblPoopsPerSec.Text = VAL(lblPoopsPerSec.Text) + 1
lblCursorCost.Text = VAL(lblCursorCost.Text) + 10
End Sub
Private Sub tmrSec_Tick(sender As Object, e As EventArgs) Handles tmrSec.Tick
If VAL(lblPoops.Text) > VAL(lblCursorCost.Text) Then picCursor.Show()
End Sub

VB.Net guess user's number from 1 to 1000

I am trying to create a guessing game that guesses the user's number from 1 to 1000. The user inputs if the number is higher or lower than the computer's guess. Based on the user's input, the computer each time halves the amount of the guess (e.g. first guess is 500, second is 250, third 125, etc, etc)
However I have encountered a problem when I am running this program. After pressing 'higher' or 'lower' for a few times, I am unable to change the output any further. I suppose this is to do with amount = amount / 2 reaching a limit where it can barely be added or subtracted into intGuess. I have tried doing amount = (amount / 2) + 1, but that sometimes doesn't allow me to get to a number.
How would I counteract this problem?
Here is my code:
Dim intGuess As Integer = 500
Dim amount As Integer = 500
Dim count As Integer = 0
Private Sub btnLower_Click(sender As Object, e As EventArgs) Handles btnLower.Click
amount = amount / 2
intGuess = intGuess - amount
lblGuess.Text = $"Is your number {intGuess} ?"
count = count + 1
End Sub
Private Sub btnHigher_Click(sender As Object, e As EventArgs) Handles btnHigher.Click
amount = amount / 2
intGuess = intGuess + amount
lblGuess.Text = $"Is your number {intGuess} ?"
count = count + 1
End Sub
Just thought I should add this, but the first guess is 500.
I play this game verbally with my young son. I tell him to guess a number from 1 to 1000 and guarantee I can guess it in 10 or fewer guesses. It is a simple binary search. You can research binary search to come up with an algorithm. It's pretty simple and I've split it up into buttons like you have. Here is my form
The code to make it work is
Private guess As Integer
Private max As Integer
Private min As Integer
Private Sub StartButton_Click(sender As Object, e As EventArgs) Handles StartButton.Click
If Integer.TryParse(MaxTextBox.Text, max) AndAlso
Integer.TryParse(MinTextBox.Text, min) AndAlso
max > min Then
makeGuess()
Else
MessageBox.Show("Error in max or min, cannot continue! Fix max and min and try again.")
End If
End Sub
Private Sub HigherButton_Click(sender As Object, e As EventArgs) Handles HigherButton.Click
min = guess
makeGuess()
End Sub
Private Sub LowerButton_Click(sender As Object, e As EventArgs) Handles LowerButton.Click
max = guess
makeGuess()
End Sub
Private Sub JustRightButton_Click(sender As Object, e As EventArgs) Handles JustRightButton.Click
MessageBox.Show($"That's right, I found your number, it is {guess}!")
End Sub
Private Sub makeGuess()
guess = CInt((max - min) / 2 + min)
GuessLabel.Text = guess.ToString()
End Sub

How can I write data into a row in Virtual Studio? (MS Access Database file"

I would like to make a small application what can make easier my work.
I have to make one ordering process some labels where I have a plan and from the plan I have to one excel list making with the labelnames what will be printed by the Manufacturer. We have a lot of type of the label (names) but they are fixing. (160 pieces differentnames).
So I make this always if I get a new plan then I make new label-list. I do it alway by hand cell by cell.. Sometime I have to filling out 400 cell for one plan... I don’t have a lot’s of time to this..
So I started making my first Windows app with Visual Studio(in Windows From – Visual Basic).
I found some cool video, so I already have the „basics”.
I connected one MS Access database to my Project where I would like to store the datas.
And now i have trouble.. I have some Comboboxes. I would like to choose some cases and then I would like to update the database where the rows will be filled with the correct values. If its done, i can this exporting to excel and sendig forward to the Manufacturer.
I have a textbox where I write the Plan name (it linked to the database first Column)
And then:
So the Combobox1 have Sektor A, B, C, D ,E, F (six value)
The Combobox2 have 09RRU, 09RSU, 18RRU ... empty - (eight value)
The Combobox3 have 21RRU, 21RSU, 26RRU ... empty - (eight value)
The Combobox4 have ja or nein (only two value)
and so on.. I have 8 Combobox.
My Idea:
If I select the Sektor A and 09RRU , the another two is empty and nein, then I click on the Update button I would like to get back in database 09.SekA1, 09.SekA2, AISG.SekA
If I select the Sektor A and 09RRU and 21RRU and ja, then after click Update, I would like get 09.SekA1, 09.SekA2, 21.SekA1, 21.SekA2, 09.21.SekA1, 09.21SekA2, AISG.09.21.SekA
….
I can every type of labels line by line writing if needed, I think I have to do this. I don’t think so can I dynamic Arrays making which can the different String e.g. ( Text (09) & Text (.SekA) & Text(1)) creating. I just now started the VB..
Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox8.SelectedIndexChanged
SektorForm1()
End Sub
Private Sub ComboBox2_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
End Sub
Private Sub ComboBox3_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox2.SelectedIndexChanged
End Sub
Private Sub ComboBox4_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox3.SelectedIndexChanged
End Sub
Private Sub SektorForm1()
BEschriftungenDataSet.Standort.RRU18Column = "18.SekA1"
BEschriftungenDataSet.Standort.RRU21Column = "18.SekA2"
BEschriftungenDataSet.Standort.RRU26Column = "AISG.18.SekA"
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Me.StandortTableAdapter.Fill(Me.BEschriftungenDataSet.Standort)
ComboBox1.SelectedIndex = 5
ComboBox2.SelectedIndex = 3
ComboBox3.SelectedIndex = 3
ComboBox4.SelectedIndex = 1
ComboBox5.SelectedIndex = 1
ComboBox6.SelectedIndex = 1
ComboBox7.SelectedIndex = 1
ComboBox8.SelectedIndex = 0
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
On Error GoTo SaveErr
StandortBindingSource.EndEdit()
StandortTableAdapter.Update(BEschriftungenDataSet.Standort)
MessageBox.Show("Saved")
End Sub
Could some one for me Helping what is wrong in my code? I tried some data inserting to tha database when I choose someting in Combobox1 but it doesn't work..
I get failures: BC30526 Property'RRU18Column' is 'ReadOnly' and BC30311 Value 'String' cannot be converted to 'DataColumn'..
And giving some help how I sould staring building up my cases to my Combobox chooses..
Thanks guys

Updating Values in a Data Grid View With Key Press Data Entry in Numeric Up and Down

I am setting up a Data Grid View that contains a list of items, with one column as the Item Number (1, 2, 3) and the second number as the name of the items. I am controlling the input of the Item Number column using a Numeric Up and Down, so when I increase it, the rows are added and the Item Number column is automatically updated (so the user doesn't have to enter this in). However, this only works if I use the numeric up and down by clicking the arrows. If I type in the number (say 4 items), I get an exception (System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index') and the procedure doesn't work. The code is below:
Private Sub numItemNumber_ValueChanged(sender As Object, e As EventArgs) Handles numItemNumber.ValueChanged
While (dgvItems.Rows.Count < numItemNumber.Value)
dgvItems.Rows.Add()
i = numItemNumber.Value
dgvItems.Rows(i).Cells(0).Value = i + 1 'This is where the exception is
End While
End Sub
I added in a KeyPress event to see if that could handle the item entered in but it doesn't.
Private Sub numItemNumber_KeyPress(sender As Object, e As EventArgs) Handles numItemNumber.KeyPress
For i = 0 To numItemNumber.Value - 1
dgvItems.Rows(i).Cells(0).Value = i + 1
Next
End Sub
How can I edit this to include both events (the user using the up and down keys or just entering the number in directly)? Thank you.
Don't you still have to Add the new row before you can enter a value in it?
Private Sub numItemNumber_KeyPress(sender As Object, e As EventArgs) Handles numItemNumber.KeyPress
For i = 0 To numItemNumber.Value - 1
dgvItems.Rows.Add()
dgvItems.Rows(i).Cells(0).Value = i + 1
Next
End Sub
Figured out this works, essentially adding a loop through the rows of the data grid view in the Value Changed event so that it can handle any number > 0. Adding the code here for anyone who possibly needs it:
Private Sub numItemNumber_ValueChanged(sender As Object, e As EventArgs) Handles numItemNumber.ValueChanged
While (dgvItems.Rows.Count < numItemNumber.Value)
For i=0 to numItemNumber.Value-1
dgvItems.Rows.Add()
dgvItems.Rows(i).Cells(0).Value = i + 1
Next
End While
End Sub
The KeyPress Event is not needed.

Formatting and Computing Numbers in Textbox VB.Net

Hello Everyone Good Afternoon.
I Hope Someone Helps me with my Problem.
I have 3 Textboxes and they are:
GrandTotal.Text
VatAmount.Text
TotalAmount.Text
and 1 NumericUpdown1.Value
Here is the Scenario, As the system goes, there is a code that will trigger and Will put a Number value in GrandTotal.Text and after that, The User will press NumericUpdown1.Value. Every time the user press it A computation will be triggered and a Number value will be Displayed in TotalAmount.Text and VatAmount.Text
To Make it more specific it is like a computation form that will include VAT. For Example.
Grandtotal.text = 2000
and if I press the NumericUpDown to + 1
VatAmount.Text = 20 and TotalAmount.Text = 2020
I hope you get what I mean
and Here is my code for It:
Private Sub NumericUpDown1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NumericUpDown1.ValueChanged
VatAmount.Text = Val(Grandtotal.text) * NumericUpDown1.Value * 0.01
End Sub
Private Sub VatAmount_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles VatAmount.TextChanged
TotalAmount.Text = Val(VatAmount.Text) + Val(TextBox14.Text)
End Sub
Now I`m done Explaining it here is My Question.
How to put Commas on that Textboxes and Compute It? My Prof. asked that He wants to put commas on the numbers that will bi inputted? No need to literally put Commas. Put it Automatically when value is greater that 3 Digits
How can I put commas in Textboxes and Compute it using the NumericUpdown?
TYSM
This is roughly what you need:
Private Sub GrandTotal_TextChanged(sender As Object, e As EventArgs) Handles GrandTotal.TextChanged
Dim input As Double = Double.Parse(GrandTotal.Text)
Dim inputStringWithCommas As String = input.ToString("N0", CultureInfo.InvariantCulture)
GrandTotal.Text = inputStringWithCommas
Dim vat As Double = Double.Parse(GrandTotal.Text) * NumericUpDown1.Value * 0.01
VatAmount.Text = vat.ToString()
TotalAmount.Text = (Double.Parse(GrandTotal.Text) + vat).ToString("N0", CultureInfo.InvariantCulture)
End Sub
It is similar to what you have, so you should be able to make it work for the NumericUpDown event as well.

Dynamically updating a progress bar in VB

Hello I am a novice / mediocre VB programmer and I made a timer that simply need to update it self every second.
I started having doubts about weather or not it was working so I applied a msg box to my timers code it went off every second updating it self but the progress bar wont? why?
Dim power As PowerStatus = SystemInformation.PowerStatus
Dim percent As Single = power.BatteryLifePercent
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer.Tick
ProgressBar1.Value = percent * 100
Label1.Text = percent * 100
End Sub
I have a power status and percent that takes the status and turn into a usable percentage then the progress bar uses that percentage but isnt updating like the msgBOX does why?
Well, your timer is probably working well and all, but you don't show where/how you get the updated value of SystemInformation.PowerStatus.BatteryLifePercent.
Maybe you're doing this somewhere else in your code, but as it is posted, you're always displaying the same value, so of course the progressbar is never going to change.
From what I can see from your question, everything should be working ok but I cant see that you have added Timer1.Interval = 1000 however you may have but this with the designer and not the coding side, however nevertheless here is how I did this project so you could see my working example just so you can be sure, If you have any problems let me know and i will do my best to help you out :)
Public Class Form1
Dim Timer1 As New Timer
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Timer1.Enabled = True
Timer1.Interval = 1000
AddHandler Timer1.Tick, AddressOf Timer1_Tick
Timer1.Start()
End Sub
Private Sub Timer1_Tick()
Dim POWER As PowerStatus = SystemInformation.PowerStatus
Dim PERCENT As Single = POWER.BatteryLifePercent
Dim ONCHARGE As PowerStatus = SystemInformation.PowerStatus
ProgressBar1.Value = PERCENT * 100
Label1.Text = "Power Remaining: " & PERCENT * 100 & "%"
If ONCHARGE.PowerLineStatus = PowerLineStatus.Online Then
Label2.Text = "Currently: Charging"
Else
Label2.Text = "Currently: Not Charging"
End If
End Sub
End Class
I added a Progressbar and two labels to the form, one of which is the computer battery and another of which will tell the user if the cable is unplugged in or not, i know you didnt ask for the cable status but i added it just incase you needed it :)
Happy Coding
