Hi There,

I amcurrently building a MDI application.

Both my Add and Edit screen use a form called frmStaffDetails.

On load, this form is redefined as 'AddStaffChild' and 'EditStaffChild' dependant on which menu item is selected.

I've defined the CurrentForm as Form.ActiveForm.ActiveMdiChild.

Within a module I am checking the text withincertain textboxes. So for example here I am checking a name has been inputted. If it has, then I will allow the record to be saved.

Public

Sub CheckStaffSave()

If

Not CurrentForm.Controls("txtFirstName").Text = "" Then

MsgBox(

"You are about to enter this record into the database do you wish to continue?", MsgBoxStyle.YesNoCancel)

If vbOK Then

SaveStaffRecord()

ClearStaffBoxes()

Else

Exit Sub

End If

The problem I am having is that this code works perfectly if the textbox control is not within a Tab Control. As soon as I put it in a tab page I get the error.

"Referenced object item has a value of Nothing"

Also if I reference it directly for example

If Not AddStaffChildForm.txtFirstName.Text = ""

this works fine too, but i want it to be more genric so I can use it for my edit screen as well.

How can I define a control within a Tab Control from a module (or any otherway to declare a public sub).

Cheers
