Every day I get from 1 to 10 emails asking me various VB questions... some I answer by pointing to a link, some by providing code, and sometimes I just point people to the newsgroups or forums that exist for this type of question... but this time I thought I'd just post the question and answer into my blog ...

I just want to ask how to make the string in to proper format..
ex...
input.
gerald

this must be the output:
Gerald

and i want it to interactively change when i'm inputing a string in a textbox..

And the answer is to put this code into the TextChanged event of your textbox;

Dim ci As Globalization.CultureInfo = _
    System.Threading.Thread.CurrentThread.CurrentCulture



Private Sub TextBox1_TextChanged(ByVal sender As System.Object, _

        ByVal e As System.EventArgs) Handles TextBox1.TextChanged

    Dim pos As Integer = TextBox1.SelectionStart

    TextBox1.Text = ci.TextInfo.ToTitleCase(TextBox1.Text)

    If pos > 0 AndAlso pos <= TextBox1.Text.Length Then

        TextBox1.SelectionStart = pos

    End If

End Sub

The key is that the CultureInfo class provides a TextInfo instance, which in turn has a method of "ToTitleCase" on it... This KB article provides more info and also shows an alternate method to achieve the same results (StrConv()).
