What is the WinForms MessageBoxAdv?
MessageBoxAdv
The MessageBoxAdv is the control that can be used to display any messages as like .NET MessageBox. MessageBoxAdv supports standard color schemes and custom color schemes in Office 2007 style. Custom Icons support is also included in MessageBoxAdv. To display Message Box, we need to invoke MessageBoxAdv.Show() method.
C#
if (this.comboBoxAdv1.Enabled)
{
MessageBoxAdv.Show("MessageBoxAdv with Default Icon.", "MessageBoxAdv " + MessageBoxAdv.Office2007Theme.ToString() + "Color Scheme", MessageBoxButtons.OK, (MessageBoxIcon)Enum.Parse(typeof(MessageBoxIcon), this.comboBoxAdv1.SelectedItem.ToString(), true));
}
VB
If Me.comboBoxAdv1.Enabled Then
MessageBoxAdv.Show("MessageBoxAdv with Default Icon.", "MessageBoxAdV " & MessageBoxAdv.Office2007Theme.ToString() & "Color Scheme", MessageBoxButtons.OK, CType(System.Enum.Parse(GetType(MessageBoxIcon), Me.comboBoxAdv1.SelectedItem.ToString(), True), MessageBoxIcon))
End If
