Need help adding number to dim's in my loop sequence? vb.net - vb.net

Question

Here's basically what I have:
Public checkprogresstime_p1 As String = ""
Public checkprogresstime_p2 As String = ""
'P1 Progress bar updater
checkprogresstime_p1 = (time_total.Text - time_p1_hour.Value)
If checkprogresstime_p1 >= 60 Then
checkprogresstime_p1 = 60
time_p1_progress.ForeColor = Color.LimeGreen
ElseIf checkprogresstime_p1 <= 0 Then
checkprogresstime_p1 = 1
End If
If time_p1_progress.Value < 60 Then
time_p1_progress.ForeColor = Color.Red
End If
time_p1_progress.Value = checkprogresstime_p1
Here's basically what I need:
Dim cnt As Integer = 1
Do
'P1 Progress bar updater
checkprogresstime_p(cnt) = (time_total.Text - time_p(cnt)_hour.Value)
If checkprogresstime_p(cnt) >= 60 Then
checkprogresstime_p(cnt) = 60
time_p(cnt)_progress.ForeColor = Color.LimeGreen
ElseIf checkprogresstime_p(cnt) <= 0 Then
checkprogresstime_p(cnt) = 1
End If
If time_p(cnt)_progress.Value < 60 Then
time_p(cnt)_progress.ForeColor = Color.Red
End If
time_p(cnt)_progress.Value = checkprogresstime_p(cnt)
Loop While cnt <= 25
I have no idea how to do it... I need it to loop and add +1, 25 times. I basically have it written out 25 times at the moment...

Answer 1

This is the For/Loop with your current request. The cnt variable will increment itself in this type of Loop.
For cnt As Integer = 1 To 25
'P1 Progress bar updater
checkprogresstime_p(cnt) = (time_total.Text - time_p(cnt)_hour.Value)
If checkprogresstime_p(cnt) >= 60 Then
checkprogresstime_p(cnt) = 60
time_p(cnt)_progress.ForeColor = Color.LimeGreen
ElseIf checkprogresstime_p(cnt) <= 0 Then
checkprogresstime_p(cnt) = 1
End If
If time_p(cnt)_progress.Value < 60 Then
time_p(cnt)_progress.ForeColor = Color.Red
End If
time_p(cnt)_progress.Value = checkprogresstime_p(cnt)
Next

I believe what you're wanting to do has more to do with having 25 progress bars on your form where each one is named time_p#_progress where # is the number of the progress bar. That being said, there are two ways to acheive updating your progress bars without having to copy and paste your code 25 times...
1. Use Me.Controls to get a reference to the progress bar
For j = 1 To 25
Dim pbar As ProgressBar = Me.Controls("time_p" & j & "_progress")
Dim ph As NumericUpDown = Me.Controls("time_p" & j & "_hour")
Dim checkprogresstime As Long = (time_total.Text - ph.Value)
If checkprogresstime >= 60 Then
checkprogresstime = 60
pbar.ForeColor = Color.LimeGreen
ElseIf checkprogresstime <= 0 Then
checkprogresstime = 1
End If
If time_p1_progress.Value < 60 Then
pbar.Value = checkprogresstime
End If
pbar.Value = checkprogresstime
Application.DoEvents()
Next
Note: You didn't tell us what type of control time_p1_hour was. I assumed it was a NumericUpDown down control. So, if it's not, you need to replace it the type of control that time_p1_hour is.
2. Dynamically create your controls as a control array
Initizliaze your progress bars in the Form1_Load method (MyBase.Load)
Private pbars(24) As ProgressBar
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
For i = LBound(pbars) To UBound(pbars)
pbars(i) = New ProgressBar()
pbars(i).Parent = Me
pbars(i).Top = i * pbars(i).Height
pbars(i).Left = 0
pbars(i).Visible = True
Next
End Sub
Put your code inside of a loop like so
For cnt = 0 To 24
checkprogresstime_p(cnt) = (time_total.Text - time_hour(cnt).Value)
If checkprogresstime_p(cnt) >= 60 Then
checkprogresstime_p(cnt) = 60
time_p_progress(cnt).ForeColor = Color.LimeGreen
ElseIf checkprogresstime_p(cnt) <= 0 Then
checkprogresstime_p(cnt) = 1
End If
If time_p_progress(cnt).Value < 60 Then
time_p_progress(cnt).ForeColor = Color.Red
End If
time_p_progress(cnt).Value = checkprogresstime_p(cnt)
Next
