I don't know VB, but it shouldn't be much different from C#: if (textbox.Text == "") MessageBox.Show("ERROR: Please enter value into height."); This is the simplest use of a MessageBox, it has an OK button.

If TextBox.Text ="" then MessageBox.Show("Please enter a value into height", "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Exclamation) End If
