Re: How do I delete the last character of a string

Take input as a string. Chop of the last character, then convert string to number.

Re: How do I delete the last character of a string

I assume you are putting your input to a textbox. So try this:

VB.NET Syntax (Toggle Plain Text)
        TextBox1.Text = InputBox("Enter number")
        TextBox1.Text = TextBox1.Text.Substring(0, TextBox1.Text.Length - 1)
        TextBox1.Text = InputBox("Enter number")
        TextBox1.Text = TextBox1.Text.Substring(0, TextBox1.Text.Length - 1)

You also could use the IsNumeric(TextboxName.Text) Then
TextboxName.Text.Length -1 as the other poster stated which will subtract the last number in the textbox

VB.NET Syntax (Toggle Plain Text)
Dim str As string 
str = "Ramy1"
str = str.Remove(str.Length - 1);
' str = Ramy
Dim str As string 
str = "Ramy1"
str = str.Remove(str.Length - 1);
' str = Ramy

Re: How do I delete the last character of a string

I need to remove the last ",-1,-1,-1" from this line

'XXXXXX XXXX `XXXXXXXXXXXX` XXXXX (XXXX,'XX','XXXX','YYYY YYY YYYYYY YYYYY YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY YYYYYYYYYYYYYYYYYYY.',Y,'YYYYY YY YYYY YYY YYYY XX.XX',X,X,-1,-1,-1)'

Re: How do I delete the last character of a string

Is that a specific example of a more general case?. For example, if the last three fields are always -1,-1,-1 then you just need to replace ",-1,-1,-1)" with ")". However, if the last three fields can take on other values then one solution would be a loop that would look for the last "," and strip off the last field. You could do (for example):

VB.NET Syntax (Toggle Plain Text)
Private Function StripLast(ByVal flds As String, ByVal numflds As Integer) As String
 
	Do While numflds > 0
		flds = flds.Substring(0, flds.LastIndexOf(","))
		numflds -= 1
	Loop
 
	Return flds & ")"
 
End Function
Private Function StripLast(ByVal flds As String, ByVal numflds As Integer) As String

	Do While numflds > 0
		flds = flds.Substring(0, flds.LastIndexOf(","))
		numflds -= 1
	Loop

	Return flds & ")"

End Function

will return the string with the last given number of fields stripped off. Sample call is:

VB.NET Syntax (Toggle Plain Text)
flds = "YYYYYYYYYYYYYYYYYYY.',Y,'YYYYY YY YYYY YYY YYYY XX.XX',X,X,-1,-1,-1)"
flds = StripLast(flds,3)
 
'flds now has the value "YYYYYYYYYYYYYYYYYYY.',Y,'YYYYY YY YYYY YYY YYYY XX.XX',X,X)"
flds = "YYYYYYYYYYYYYYYYYYY.',Y,'YYYYY YY YYYY YYY YYYY XX.XX',X,X,-1,-1,-1)"
flds = StripLast(flds,3)

'flds now has the value "YYYYYYYYYYYYYYYYYYY.',Y,'YYYYY YY YYYY YYY YYYY XX.XX',X,X)"

Is this what you intended?
