MSGBox: Check empty date field, checkbox control

[Dököll]

Me again!

I have been battling this one for months. Wrote below to aid in getting certain subforms to hide once checkbox named Active is clicked. I am hoping to make the code work for Date fields that may be empty. I think i am going about it the wrong way:

Private Sub Active_BeforeUpdate(Cancel As Integer)
 
'On current event of main form
'Check if checkbox is selected
'then show or hide subform
    If Me.Active = True Then
        Me.InfoOnly.Visible = True
    Else
        Me.InfoOnly.Visible = False
    End If
End Sub
 
 

I tried:

Private Sub Active_BeforeUpdate(Cancel As Integer)
 
'On current event of main form
'Check if checkbox is selected and contact date field is empty
'then pop up an error message
 
    If Me.Active = True And Me.ContactDate Is Null Then
        MsgBox "Please add a contact date to continue..."    
    Else
        ...
    End If
End Sub
 
 

It is not working. In fact, now and then I get an error that something or other is missing, not always, but I do get that. For now, I get nada, code is mute, no errors though, just does not do anything;-)

Can you help? Thanks!

Dokoll,
Try placing your code in the <<AfterUpdate event of your checkbox>>. You want to hide your subform and check for nulls <<after>>> the checkbox has been checked. If you use the BeforeUpdate code you are presently using, your checkbox will not have been checked, so naturally nothing happens.

Hello puppydogbuddy!

Thanks for your reply. My subform example works great. What I needed was to use the same code to search for instances where ContactDate field is empty, among others, if user checks the checkbox named Active. Also tried:

 
If Me.Active.Value = True And Me.ContactDate.Value = True Then
  la la la
 
Else
 
 MsGBox "Hummm!"
 
End If
 
 

Did not get what I expected there. This was a test with one date field, but there are others included...If we can find a solution, that'd be awesome. Can use it elsewhere in the system. But I did come up with another option to aid the user.

Attempted an update query to find instances where Active = False And ContactDate = True (among other date fields) and system updates for the user. I kind of like this one since it minimizes work load for our users (especially if they forget to do it everytime).

Module code:

 
Option Compare Database
 
Sub RunMultiSQL()
 
  DoCmd.SetWarnings False
 
  DoCmd.RunSQL ("UPDATE Data_Central SET Active = True WHERE ContactDate Is Not Null")
  DoCmd.RunSQL ("UPDATE Data_Central  SET Active = True WHERE OpenDate Is Not Null")
  DoCmd.RunSQL ("UPDATE Data_Central  SET Active = True WHERE CloseDate Is Not Null")
 
  DoCmd.SetWarnings True
 
End Sub
 
 

This works great but the only problem is if either of the date fields are found to have data, Active is True. I don't want that. So I tried:

 
Option Compare Database
 
Sub RunMultiSQL()
 
  DoCmd.SetWarnings False
 
  DoCmd.RunSQL ("UPDATE Data_Central SET Active = True WHERE ContactDate Is Not Null And OpenDate Is Not Null And CloseDate Is Not Null ")
 
  DoCmd.SetWarnings True
 
End Sub
 
 

While I have no errors, Active does not record True where dates are available.

Any ideas, and thanks for your input!

Hi Dököll,

Change this line:
If Me.Active.Value = True And Me.ContactDate. Value = True Then

To This:
If Me.Active.Value = True And IsNull(Me.Conta ctDate) Then

Works like a charm:-)

Super thanks, puppydogbuddy!

So simple...

What I found out is if I select an already selected checkbox, I still get prompted to add info. I could not figure out how to supress that, so I decided to get rid of the checkbox after it has been checked and make reappear only when the save button has been pushed. On Current through the form aid in making this possible.

On Current:

 
Private Sub Form_Current() 
Me.Phoned.Visible = True 
Me.Emailed.Visible = True 
End Sub 
 
 
To make sure I do not have to check the checkbox again, since first attempt clears after prompt.  When I enter the ContactPerson textbox, Phoned checkbox is checked automatically, works in conjunction with the ON current event, then disappears.  So I do cannot get prompted because the checkbo has vanished.
 
On Enter 
 
Private Sub ContactPerson_Enter() 
Me.Phoned = True 
Me.Phoned.Visible = False 
End Sub 
 
Private Sub Email_Enter() 
Me.Emailed = True 
Me.Emailed.Visible = False 
End Sub
 
 

What I think may be needed is a way to skillfully go through the ContactPerson and Email textboxes to validate the email or phone number added there, keep bogus ones out.

There has to be a code for that.

But this is where we are for now puppydogbuddy, thanks for reading my rambling and again thank you. You really got me going with this one.

Oh, here's another thing that may be needed. If user must add precise information, it'd be nice I could make sure the character length of the Comment field is at least 255 chars long.

I thought of setting legal words like 'unavailable' , 'not in service', and so one for the comment box so I'd know user did in fact attempt to add added info in comment, but each user enters info differently and may just say, 'no email' or something not included in the code.

Also may not satisfy the idea to have added info, credible info to figure out why a dummy email or phone had to be added.

If I can figure this out, it should be added to the above, perhaps then as an Article, I think that'd be good there

In a bit!
