Save or Cancel a record input to a table.. dirty event?

[snipe]

So with my payroll form.. (June7 I'm assuming you'll be solving this one for me too)

I have the HR user input the desired info in the fields in the form. I don't want that data to go to the table until they hit a save button. How do I go about this? I googled and got a bunch of info about the dirty property, but I didn't really catch on how to use it.

Edit: This form is purely a data entry form, they can't even see the previous entries.

There are two basic strategies.

First, you can keep all those fields unbound, and have the Save button validate the valuse and then execute VBA to insert the record into the table.

Second, you can trap attempts to leave the form before the save, and delete/undo the record at that point.

You could try having your save button say

Private Sub cmdSave_OnClick()
   Me.Dirty = False
End Sub

thus saving the record, and your other relevant events say

Private Sub Form_BeforeUpdate()
   If Me.Dirty Then Me.Undo
End Sub

I believe BeforeUpdate is the proper place.

Sorry to bring this thread back.

I understand what the Dirty property means with true and false. But in the code above, you have "If Me.Dirty then...."

I'm reading that as "If Me.Dirty equals what?"

Shouldn't it be "If Me.Dirty = True then...."??

Either or will work. If it is more intuitive for yout when you read your code then use the.... = True

[Dal Jeanis]

When a variable is boolean (Yes/No or True/False) then "IF MyBoolVar Then" has the same effect as "If MyBoolVar = True Then".

However, the prior coding is more efficient.

Under some compilers, the second version will first evaluate MyBoolVar, then compare that resulting value to the value of the static value "True", and then do the jump if they match.

That being said, you are the one who has to support the code, so write it in a way that will be clear to you when you have to debug or modify it.

A couple of problems:

Private Sub cmdSave_OnClick()
   Me.Dirty = False
End Sub

Although we refer to the OnClick event, the Sub Header would actually be

Private Sub cmdSave_Click()

That aside

Private Sub Form_BeforeUpdate()
   If Me.Dirty Then Me.Undo
End Sub

the Form_BeforeUpdate event will only execute if the Form is Dirty. If it's not Dirty, the event will not fire, and if it doesn't fire, the Record can never be Saved! Since the Form is Dirty, when the Form_BeforeUpdate executes, then

Private Sub Form_BeforeUpdate()
   If Me.Dirty Then Me.Undo
End Sub

means, once again, that the Record could never be Saved! And because of this, Access will not allow code like this, and will pop an error.

While there are hacks out there to do what you want (I have one of John Vinson's archived that I can give you) why not simply let Access work as it is intended to work, and using the Form_BeforeUpdate event, ask the user if they want to Save the Record or dump it as they leave the Record or Close the Form?

Private Sub Form_BeforeUpdate(Cancel As Integer)
If Not (Me.NewRecord) Then
  If MsgBox("Would You Like To Save The Changes To This Record?", vbQuestion + vbYesNo + vbDefaultButton1, "Save Changes to Record ???") = vbNo Then
   Me.Undo
  End If
Else
  If MsgBox("Would You Like To Save This New Record?", vbQuestion + vbYesNo + vbDefaultButton1, "Save This New Record ???") = vbNo Then
   Me.Undo
  End If
End If
End Sub

You can still add a "Save" button, if some users expect it, merely having it set up to force a Save; using

DoCmd.RunCommand acCmdSaveRecord
