[02/03][Resolved] declaration issue--4th post onwards

[indiewolf]

i am trying to shorten my code, so instead of having errorprovider for each textbox i want to programatically reduce using something like the following.
although i dont get any errors, it doesnt do the work either.please help
cheers
For Each txerr As Control In firstMdiChild.Controls
If TypeOf txerr Is TextBox Then
'here i want to declare many textboxes , two in this example.
'if i declare one it works, but as soon as i declare more it doesn't work.
Dim errpro() As String = {"TextBox6", "TextBox7"}
'here i am comparing the name of the textbox with errpro
If txerr.Name Is errpro Then
ErrorProvider1.SetError(txerr, "Cannot leave blank")
Else
ErrorProvider1.SetError(txerr, "")
End If
End If
Next
