if you want a number displayed in currency format use FormatCurrency()

so you can have a person enter a number into the textbox then in the lostfocus event you can format it for currency:

Private Sub Textbox1_LostFocus (...) Handles Textbox1.LostFocus
  Textbox1.Text = FormatCurrency(Textbox1.Text)
End Sub

as far as checking a string to see if it's in currency format you can use Mid() so see if the first character is a "$" and there's at least 1 period with no letters (only numbers)

also the IsNumeric() function is your friend for checking to see if something is a number or not as well

i don't wanna put the $ sign in my text box
basically i just wanna validate the textbox to accept value like

23.98 or 1999.50
