User input validation VB.Net

Hopefully from the below people can understand what i am trying to do.....

I have a masked text box array created at runtime (00:00 mask) and wish to make sure that time entered is valid. I have been racking my brains at this all day and have not come up with a solution perhaps experts here will be able to stop me from going completely crazy. I have the below code but when i run the application i am still able to enter an invalid time.

Blocksoff(z) = New MaskedTextBox
With Blocksoff(z)
.Left = 355
.Top = 52 + (z * 25)
.Height = 20
.Width = 35
.Mask = TMask
.ValidatingType = GetType(System.DateTime)
End With
Me.Controls.Add(Blocksoff(z))

Any help with input validation would be much appreciated.

Thanks in advance

I have split the points as both are valid solutions. I have tried both and they both work. Many thanks experts :-)

I have used the second solution and given more points as it is a more complete answer with code.
