Detalhes do projeto


Restringir a "TextBox" para receber SOMENTE NÚMEROS com somente uma linha de código:

if (!(e.KeyChar >= '0' && e.KeyChar <= '9') && e.KeyChar != 8) e.Handled = true;

Private Sub TextBox1_KeyPress(sender As Object, e As KeyPressEventArgs) Handles TextBox1.KeyPress

    //Escreve-se em VB 6 assim:

    //Written in VB 6 as follows:

    //If InStr("0123456789", Chr(KeyAscii)) = 0 nd KeyAscii <> 8 Then KeyAscii = 0

    //Migrado para VB.NET:

    //Migrated to VB.NET:

    //If InStr("0123456789", e.KeyChar) = 0 And Not Convert.ToInt32(e.KeyChar) = Keys.Back Then e.Handled = True

    //Melhorada a Migração:	

    //Improved the migration:

    //If Not Char.IsNumber(e.KeyChar) And Not Convert.ToInt32(e.KeyChar) = Keys.Back Then e.Handled = True

    //E C#

    //And C#

    if (!(e.KeyChar >= '0' && e.KeyChar <= '9') && e.KeyChar != 8) e.Handled = true;

End Sub
