Mask Edit Control

How can I reset the text in Mask Edit Control?
for example, I can reset the text in TextBox using TextBox1.ResetText() OR TextBox1.Text = "". But why Mask Edit Control

VB Code:

MaskEdit.ResetText()

cannot be used?

It didn´t work with maskedit.text="" ?
or maskedit.text=DBNull.Value ?

yeah, it didn't work, but never mind, I used another way to do this and it worked!!

VB Code:

MaskEditTime.SelStart = 0
        MaskEditTime.SelLength = 5
        MaskEditTime.SelText = ""
