A Better Mouse Trap...
Jun 20, 2006
Hi,
I need a way at preventing users from using the scroll funtion on mouses from creating a multitude of balnk records and hence was looking at ghudson better mouse trap as a way of doing this... this is the way forward isnt it?
Looking at the code it starts with...
'For those of us not using Access XP, we have a challenge to prevent
'our users from advancing to another record if they do not use the controls
'we want them to use or to prevent them from bypassing our validation
'procedures too ensure the current record is okay to be saved.
How do you prevent this from happening in Access XP?? Access XP = 2002 does it not?
Regards
H.

First off sorry about the really bad layout…..I don’t know how to do all the fancy stuff but really wanted to share this because it seams like a lot of people wanted help with this.
So here is what I have going on.
I have a form to add a record, and I have a number of fields, then an “Add Record” button and a “Cancel Record” Button. What I wanted to do was:
A: Stop the form from going to another “New Record Form” when moving the mouse wheel
B: Stop the form from going to another “New Record Form” when pressing the “Tab” key
Here is what you got to do to solve the mouse problem:
1.) Create a field in the form that has the Name “MouseWheel Move”, and set the “Visible” property to “No”
2.) Enter the Fallowing:
Private Sub Form_Load()
Me![MouseWheel Move] = "No"
End Sub
3.) Enter The Fallowing:
Private Sub Form_MouseWheel(ByVal Page As Boolean, ByVal Count As Long)
Me![MouseWheel Move] = "Yes"End Sub
4.) Enter The Fallowing:
Private Sub Form_BeforeUpdate(Cancel As Integer)
If Me![MouseWheel Move] = "Yes" Then
DoCmd.CancelEvent
Me![MouseWheel Move] = "No"
End If
End Sub
Here is what you got to do to solve the Tab problem:
The last item on my form is my “Cancel” button; so when the focus is on my “Cancel” button (ie. the last item on the form) and I press tab I want the focus to go to the first field on my form.
Private Sub Cancel_Button_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = 9 Then
Me![Field Name for the First Item on the Form].SetFocus
End If
End Sub
One more thing, I am using Microsoft Access 2002 (10.6771.6735) SP3 and it works fine

I'm using GHudson's A Better Mouse Trap code. It works great. However, I added other code from http://www.databasedev.co.uk/image-form.html to get and save the path to image files and now I think there is a conflict between the sets of code.
The Images tab on the form frm_CreateNewSpec is where I have problems. The error messages are definitely from Mouse Trap...I just don't know how to resolve the problem.
I've probably missed something simple, but don't know what.
Any and all assistance is greatly appreciated by this novice.

I'm using Pat Hartman's code to select items from a list box and then append the records to a table. If a user doesn't select anything before clicking the buttom I'm trying to give them an error message. I've tried it in various places but can't get it to work. The attached is giving me the error message regardless of whether they have selected anything or not.
On Error GoTo Err_CreateAttendanceRecords_Click
Dim i As Variant
Dim dbs As DAO.Database
Dim rst As DAO.Recordset
Dim qd As DAO.QueryDef
Set dbs = CurrentDb
Set qd = dbs.QueryDefs!qrynewvaluations2
Set rst = qd.OpenRecordset
If i = 0 Then
MsgBox "You must select at least one property before continuing"
Exit Function
End If
For Each i In ctlref.ItemsSelected
rst.AddNew
rst!valprop = ctlref.ItemData(i)
rst!valdate = Me.txtValDAte
rst.Update
Next i
Set rst = Nothing
Set qd = Nothing
MsgBox "Records Created"
exit_createattendancerecords_Click:
Exit Function
Err_CreateAttendanceRecords_Click:
Select Case Err.Number
Case 3022 'ignore duplicate keys
Resume Next
Case Else
MsgBox Err.Number & "-" & Err.Description
Resume exit_createattendancerecords_Click
End Select
Any suggestions?
Thanks
Dawn

If you open the attached sample you will see what my problem is.
I have Form /Subform with look up combo that will not allow duplicate entries in same subform record. This works fine, access displays an error when a duplicate has been added as it should. What I want to do is trap that error myself and display a msgbox that will allow the entry to undo (the msgbox undo etc I can handle, it the trapping of the error)
Thanks in advance.

I have a form with 22 data fields.
There are 4 entry flow paths.
(1) is 1 to 9, 10, 20 to 22
(2) is 1 to 9, 11 to 14, 20 to 22
(3) is 1 to 9, 15 to 17, 20 to 22
(4) is 1 to 9, 15 to 17, and stop at 19.
If information is in Field 10, then I need to prohibit entry in the other 3 paths.
How can I do this?

I know this topic has been covered over and over but I've searched and searched and can't find my answer. I did find one post with a link to a possible answer but the link was broken.
My form has a required field. When a user attempts to X out of the form I have code in the Before Update event that checks this field and if it is blank:
MsgBox "Payment Terms must be filled in before closing the form"
Me.PaymentTerms.SetFocus
Cancel = True
The message box appears, but then the
You can't save this record at this time...blah blah blah.....
dialog appears and then the form closes.
How can I prevent the user from closing the form if this field is blank? It seems like once the X is clicked there is no turning back. I realize that I could remove the close button (X) from the form and use a command button instead but this may only mess up the users who have been using this DB for years. Is there any way to go backward once the close button has been clicked?
Thanks for your help.

Hi, this a great forum and i'm asking for help :)
1.i trapped error 3314 and other errors at my custm buttons(save,edit...) but...
at my 2 forms(one single and the other continuous, access gives me an error about an empty field in a table (primary id), when i press tab (it moves to next record).
The same action has my continuous form when i click at an empty field at next record or pressing tab with empty values at primary fields.
What can i do to post my own messages?
2. I have a text box (a) that takes value form an other text box (b): b=2*a. both text boxes send values to a table
How can i prevent user from chanching the value on (b) text box?
thanks in advance

How do I programmatically force an error dialog to make a certain choice?
I'm able to trap the dialog via the following code:
Private Sub Form_Error(DataErr As Integer, Response As Integer)
If DataErr = 7787 Then 'record updated by another "user" (subform)
MsgBox "Error trapped!"
Response = acDataErrContinue
Else
Response = acDataErrDisplay
End If
End Sub
Problem is, if I bypass the 7787 error in this manner, it defaults to dropping the changes, rather than saving the record, which is what I want. (Both are choices on the dialog.)
Any help would be most appreciated.

Hi everyone
I posted this question about an hour ago but I seem to have been logged out by the time that I actually pressed "send", so I don't know whether it was posted correctly - I can't find it!
I've created four buttons on a form to negotiate my way through the records. When I come to the end, a message box is shown stating that the next record cannot be found (it doesn't exist). Can I trap this message and use it to activate some code? I thought about a form popping up (in "corporate" colours to match the remainder of the database) or a form asking whether I want to add another record.
I looked at the code that Access generated when I made the buttons, and I saw the following:
Err_MyButton_Click:
MsgBox Err.Description
Resume Exit_MyButton_Click
I "remmed" out the middle line, but the automatic message box still appeared. I added a line of code: <MsgBox Err.Number>, but that didn't give a result, so I guess that the message box that's being shown isn't generated via this snippet of code.
I know that I could disable the relevant button when the record number reaches the end or add another button to add a new record, but I'd like to trap this automatic message box. Can I do so, and, if so, how?
Thanks for your time.

i am using access against an Oracle DB through an ODBC driver, and when appending records to a local table, if access gets an Oracle record error "#deleted", the append query aborts. . . that's fine, but I can't figure out how to trap the error to get the rest of the records. . .
ugh! see attached graphic
thanks

Hi, I have a button in a form that loads a report, if there is no data in the report then 2 error messages are displayed, however as these messages have no affect and they do no harm as such I would like to prevent them from being displayed. The error messages are error 91 “invalid use of isnull” error and error 2501 “cancel event error message”
I’ve been able to prevent either error 91 from being displayed or alternatively 2501 using a single if statement but not both of them together using two if statements.
(If error 94 is displayed, I would still like the report to open, error 2501 is displayed after the report is closed if there’s no data & i just want this message not to be shown)
Any ideas what im doing wrong? :confused: any help much appreciated
Regards
Kevin
Below code works ok (to trap just the one error message):
Err_cmdPreview_Click:
If Err.Number = 2501 Then ' ignore cancel event error
Else
MsgBox Err.Number & " - " & Err.Description
End If
Resume Exit_cmdPreview_Click
End Sub
But the below code here doesn’t work (when I use 2 if statements to try & trap both of the error messages)
Err_cmdPreview_Click:
If Err.Number = 94 Then ' ignore isnull error
DoCmd.OpenReport stDocName, acNormal
Else
If Err.Number = 2501 Then ' ignore cancel event error
Else
MsgBox Err.Number & " - " & Err.Description
End If
Resume Exit_cmdPreview_Click
End Sub

I have a Composite Index to prevent duplicates I get the error message. How can I trap this?
I resolved it with this PHP Code:
'Trap Error.
Dim DataErr As Integer
Dim Response As Integer
Dim Message As String
If DataErr = 3022 Then 'Duplicate value entered
Response = acDataErrContinue
End IfÂ

I am importing .txt files into Access table via VBA code (i.e., not via Saved Import Spec). Is there a way to trap the error if a particular field does not get imported due to incorrect format? When you import via Saved Import Spec and there are errors in formatting, Access generates an 'ImportErrors' table, which tells you which fields could not be updated.
Is there a way to generate a similar 'ImportErrors' table with VBA error checking?

hey all I am having a problem, and most people dont seem to know what to say and not to give me any ideas. So here we go. I have a form which you can scroll through the reocrds, with the mouse wheel, or through the navagation command buttons with I have created. However when I use my mouse wheel the record changes but it doesnt change my activeX Control. When I use my command buttons it changes. However I would like to have both the options so anyone have any ideas on how to get the activeX Control to change with the rest of my record?? Thanks

In Access (2003) I was able to (by default?) scroll through records with the mouse scroll wheel. That no longer works. How can I have the form scroll backwords and forwards with the mouse wheel?
I've been reading threads and it sounds like MS "fixed" a feature that I was relying on heavily to move through records. I can't find a way to enable it again......

Hi all,
I have read much about disabling the mouse scroll bar - but my problem is that while I want the use of the scrollbar, it is very jumpy.
Does anyone know how I can control the functionality of the scroll bar?
Cheers
