Limit the size of string

[Sehboo]

Hi,

Is there any easy way to limit the size of the string?

I have

Private msDescription As String

I want to limit the msDescription to 50 instead of unlimitted.

I wish I could do something like

Private msDescription As String(50)

How to achive this?

Thanks

You can use a StringBuilder object instead of a String.
Here's a nice explanation:

Dim x as New StringBuilder(50,50) 'Creates a string builder with 50
characters and a maximum of 50 characters
x.Append("Hello") ' Appends data to x

You could make a property of type string, then in the accessor verify its
length and either throw an exception or just disallow it.

Just FMI: Why? As you are responsible for assigning something to the
string, you can easily check the length before assinging something.

Hi Sehboo.

Private myDescription as String
Private msDescription As String

myDescription = msDescription.substring(0,50)

I hope this helps,
