Description: We want the users to
notice there is something missing in
textboxes before changing forms or
updating records, the following code in
the update-command button serves the
checking:
Code:
Option
Explicit
'
Private Sub cmdUpdate_Click()
Dim ctr As Control
'
'====================================
' CHECKING EMPTY TEXTBOX SUBROUTINE
'====================================
'
'looping through the entire control
collection
'in current form. "Controls" is
a Collection
'of all controls on form
For Each ctr In Me.Controls
'use "TypeOf" function to
identify TextBoxes
If TypeOf ctr Is TextBox Then
'check if the TextBox control has no Text
If ctr.Text = vbNullString Then
MsgBox "TextBox information
missing"
ctr.SetFocus
'Setfocus back to TextBox
Exit Sub
'This is to get out
End If
End If
Next ctr
'
'====================================
'Here you need to enter what you should
do
'for thus buttons (e.g., Update, Exit,
New form etc.)
'in case all TextBoxes have text.
'====================================
' End Sub
