How to make an output in a visual basic console app span the entire width of a terminal window?
Is this possible? Can it be done by using a function of some sort. All i can find is examples on how to make an output span the width of a text box within a visual basic windows form app.
My code is below.
Sub Main()
Dim usrnum(1), usramount, userchoice, count, result2 As Integer
Dim totalstars(1), question1, userchoice2, nchrt, result1 As String
Do Until question1 = "y"
userchoice = 0
Do Until userchoice = 1 Or userchoice = 2
'menu - text tries to be as specific as possible to prevent an incorrect input from the user
WriteLine("------------------- Bar chart creator! ---------------------")
WriteLine(" ")
WriteLine(" ")
WriteLine("===============================================================")
WriteLine("************************** MENU ***************************")
WriteLine("===============================================================")
WriteLine(" ")
ForegroundColor = ConsoleColor.Cyan
WriteLine(" 1 - To begin ")
ForegroundColor = ConsoleColor.Yellow
WriteLine(" 2 - To exit ")
WriteLine(" ")
WriteLine(" ")
WriteLine(" ")
WriteLine(" ")
'reads in data from the user from the menu
Try
userchoice = ReadLine()
Clear()
Catch ex As Exception
'if this produces an error, for example a string is entered by the user then the following message will be issued to the user
WriteLine("That value is unknown!")
WriteLine("Please enter an Integer only")
End Try
If userchoice = 1 Then
WriteLine("What would you like to name your bar chart as?")
nchrt = ReadLine()
Clear()
WriteLine("Enter the amount of values you want to enter.")
Try
usramount = ReadLine()
Catch ex As Exception
'if this produces an error, for example a string is entered by the user then the following message will be issued to the user
WriteLine("That value is unknown!")
WriteLine("Please enter an Integer only: ")
End Try
Clear()
WriteLine("Values for the chart " & nchrt)
WriteLine("")
WriteLine("Please note! Each * Is equal To 100. Once a value reaches over 1000 the maxium amount Of * shown Is 10")
WriteLine("")
ReDim usrnum(usramount) 're-assign the users input as the value for the arraysize
ReDim totalstars(usramount)
count = 0
'the count allows the user to see what how many values they have entered so far and what number they are currently on
While count < usramount
For i As Integer = 0 To usrnum.Length - 1
'allows the users numbers to be recorded into the array
WriteLine("Please enter value " & count & " And <press> enter")
Try
usrnum(i) = ReadLine()
count = count + 1
Catch ex As Exception
'if this produces an error, for example a string is entered by the user then the following message will be issued to the user

You can query the Console.WindowWidth property, and adjust your output to fit.
