Forms :: Undo Only One Field On A Form?
Jul 14, 2014
I need to program vba to "Undo" only one field on a form, not the entire form. The user enters a number of fields and then tabs to a text field which allows them to enter an 8 digit code. If this code matched one already in the database, I have a message box telling them of the match and offering to either clear the entry or to allow them to go back and edit what they have entered. The 2nd part of this works fine, but I can't figure out how to just clear the text box without clearing the entire form. (the form is bound to a table)
I have tried DoCmd.RunCommand acCmdUndo which clears the entire form.
Me.TextBox.undo does nothing at all.
(a search found several websites that say use Me!TextBox.undo, but that doesn't pass the complier)...

I have some forms where I can cancel my input. However this works only on the current record. When I implement a subform this does not work anymore. Because access auto saves when focus is set to the subform.
I don't wan't to use unbound forms. What I would like to do is when I press EDIT that a snapshot or something is taken of the current values. So I can set them back.
I can use variables for the main form, but I don't know how to save the values of the records of the subform.
Or does the possibility exist to use transactions?
I just want to be able to undo all changes regardless of the subforms.

I thought "Undo" was only available while in the current record.Here were my steps:
1 - Loaded form that shows 1 record per form page.
2 - Edited a record
3 - Moved to another record with status bar nav arrow
4 - Verified my edit was in the underlying table
5 - Moved back to the original record, again using status bar nav arrow
6 - Clicked my "undo" control and the original data appeared in the form
7 - Moved to another record
8 - Verified my original data was now back in the underlying table
My undo control has this vba on click:
Code:
DoCmd.RunCommand acCmdUndo

Could someone look at my code and tell me why my “Me.TargetDate.Undo” won’t work?
First, let me say that the TargetDate field has an On-Click event that calls a module written by Allen Browne), which is shown below and works great.
=CalendarFor([TargetDate],"Select a date from the calendar ")
What happens is that the Me.TargetDate.Undo event always keeps the date selected in the calendar.
Based on something I read from Rual Guy on another issue, I’ve used the TargetDate_LostFocus routine to check for some additional data entry errors. I’ve tried moving the code in “Private Sub TargetDate_Exit(Cancel As Integer)” to the LostFocus, but it doesn’t make any difference to the Undo. I’ve also tried “I’ve tried “Private Sub TargetDate_Change(),Me.Undo…” but that doesn’t work either. :confused:
Private Sub TargetDate_Enter()
If Not IsNull(Me.TargetDate) Then
OldTarget = Me.TargetDate
End If
End Sub
Private Sub TargetDate_Exit(Cancel As Integer)
If Not IsNull(Me.TargetDate) Then
If DateDiff("d", Me.DateOpened, Me.TargetDate) < 0 Then
MsgBox "You have selected a date that is before…bla bla"
Me.TargetDate.Undo
Me.TargetDate.SetFocus
ElseIf DateDiff("d", Date, Me.TargetDate) < 0 Then
MsgBox "You have selected a date that is prior to today's date…bla bla"
Me.TargetDate.Undo
Me.TargetDate.SetFocus
ElseIf Weekday(Me.TargetDate) = 1 Or Weekday(Me.TargetDate) = 7 Then
MsgBox "You have selected a date that falls on a weekend..bla bla"
Me.TargetDate.Undo
Me.TargetDate.SetFocus
End If
End If
End Sub
Private Sub TargetDate_LostFocus()
If Me.TargetDate > OldTarget And Me.cboAssignToID <> OldAssignee Then
MsgBox "The target date can only be changed if …bla bla"
Me.TargetDate.Undo
Me.TargetDate.SetFocus
End If
End Sub
Ever thankful for this forum,
Christine

I have a form with an undo button which works fine...sometimes.
The issue is if the user hasn't clicked out of the text box they have updated before clicking the undo changes button only the changes they have made to that text box are un-done.
My question is when the user clicks the undo chnages button how do I code it so the changes to the whole form are undone even if they haven't clicked out of the last text box they updated.

I have a Memo box where the user puts comments and then I have a check box that if check automatically puts a specific phrase on the first line of the Memo box (before any other text currently in the box). What I am trying to do is have it so that if the "check box" is UN-checked it will remove the line that it just added to the Memo box. I have been able to get it to undo everything in the Memo box, but what I really need is for it to just undo the last line of text that was enterd when the user checked the box.
Example:
Memo Box:
This is the line that the checkbox just added when the checkbox is set to "True"
This is the test data the user has already put in the box...
==================
User now UN-checks the checkbox (I want the Memo box to read.. see below) Thereby deleting the line "This is the line that the checkbox just added when the checkbox is set to "True""
Memo Box:
This is the test data the user has already put in the box...
How can I accomplish this?

Hi, I have found the answer to most of my problem, thanks to previous posts.
I am using the Undo command on a Date field. However it seems that my code is maybe not staying on the event to action the undo.
After it runs the Focus goes to the next field Me.LeaveDays and the value is automatically entered, unless I comment back in the Goto's in which case the value will be zero.
I want to be able to Undo the EndDate (and preferable the StartDate, and Setfocus to StartDate) EndDate will do if not possible.
Don't want to Undo the whole form, although that could be a last resort.
My code is in the before_update event, image posted (ignore faded fields, not visible/needed in final solution)
Private Sub EndDate_BeforeUpdate(Cancel As Integer)
On Error GoTo Err_EndDate_BeforeUpdate
Dim intLeaveLeftAL As Integer
Dim intLeaveLeftSL As Integer
Dim intLeaveDays As Integer
Dim dtNullDate As Date
Dim varNullField As Variant
intLeaveLeftAL = Nz(Forms!frmAddLeaveRecords.fsubLeaveAgTots.Form![DailyALInc] - (Forms!frmAddLeaveRecords.fsubLeaveAgTots.Form![ALDays] - Forms!frmAddLeaveRecords.fsubLeaveAgTots.Form![ACDays]), 0)
intLeaveLeftSL = Nz(10 - Forms!frmAddLeaveRecords.fsubLeaveAgTots.Form![SLDays], 0)
' Use the WorkingDays function to calc the number of Leave Days
' set LeaveDays and requery the form
intLeaveDays = WorkingDays(Me.StartDate, Me.EndDate)
If Me.LCode = "LC41" Then ' Sick Leave
Select Case intLeaveDays
Case Is > intLeaveLeftSL
MsgBox "Employee does not have enough Leave" & vbCrLf & "to take as Sick Leave.", vbCritical + vbOKOnly + vbDefaultButton1, "Entry in Error"
varErrorCondition = True
Me.EndDate.Undo
GoTo Exit_EndDate_BeforeUpdate
Case Else:
End Select
ElseIf Me.LCode = "LC11" Or Me.LCode = "LC13c" Then ' Annual or C/Fwd Leave
Select Case intLeaveDays
Case Is > intLeaveLeftAL
MsgBox "Employee does not have enough Leave" & vbCrLf & "to take as Annual Leave.", vbCritical + vbOKOnly + vbDefaultButton1, "Entry in Error"
varErrorCondition = True
Me.EndDate.Undo
GoTo Exit_EndDate_BeforeUpdate
Case Else:
End Select
End If
Me.LeaveDays = intLeaveDays
Me.LeaveDays.Requery
varErrorCondition = False
Exit_EndDate_BeforeUpdate:
Exit Sub
Err_EndDate_BeforeUpdate:
MsgBox Err.Number & " - " & Err.Description
Resume Exit_EndDate_BeforeUpdate
End Sub
The ifs and cases work fine, just like to send the User back a few steps
appreciated :) :)

It has really been awhile I posted in this forum
I have a form purchase order details, that I used to enter quantity of items purchased. I found out that I can't delete quantities entered on the form. It appears to delete, but on checking the quantity in the inventory, it was not deleted. The vba code in my quantity section of the page is this
Quantity_AfterUpdate()
Dim IT As InventoryTransaction
If Me![Quantity] = 0 Then
RemoveCurrentLineItem
End If
AddPurchase Me![Purchase Order ID], Me![Item ID], Me![Quantity], NewInventoryID
End Sub

This frame controls an option group. If they are in an existing citation and want to start one for another type, this offers to write a new record in when they try to switch. Problem is, if it DOES write the new record, it seems to be saving the old record, and thus both will end up 56, for example. Access seems to be ignoring/overwriting the Me.frameCitationType.Undo (I don't want to use Me.Undo because they may have made other changes as well).
If the user does not spawn the new citation, it undoes fine. I suspect the problem may be the Filter/FilterOn?
Code:
Private Sub frameCitationType_BeforeUpdate(Cancel As Integer)
Dim chap As Integer
Dim othercit As Variant
Dim curRecord As DAO.Recordset
Dim curDefend As DAO.Recordset
If Me.NewRecord = True And IsNull(Me.CaseNumber) Then
MsgBox "Enter the Service Order and Increment first, please.", vbExclamation
[Code] .....

I'm using the following code to ask the user whether to save changes to the data, don't save changes or Cancel the close and continue editing. I'm closing the form using the 'X' only.
Code:
Private Sub Form_BeforeUpdate(Cancel As Integer)
Dim UserResp As Integer
UserResp = MsgBox("Record(s) have been added or changed." & vbCrLf & "Save the changes?", vbYesNoCancel)
Select Case UserResp
[Code] ....
The problem I'm having is when I press the 'Cancel' button in the message box. When I press 'Cancel' the form remains open (bPreventClose=True) which is what I want. But the changes to the data get undone even though I don't have Me.Undo in that case.
First, what's causing the undo?
Second, how do I prevent the data from undoing when I press 'Cancel.'
I went to add a record earlier and selected 'Cancel' because I wanted to change one small item. I lost all the data I had put in and had to start over.

How can I get the value from a field in one table (in the sub form) to copy/insert into a field in another table (in the main form) when adding a new record?The main form and sub form are linked using parent/child linking, and the sub form is in a tab.I have table A (Visit Dates) in the main form which is used to record the date of a visit to a church. Table B (Quarters and Peals) is used to record an event that took place at that church during that visit. Note that not all visits in table A require a record to be created in table B - but half or more do.
In tables A and B I have a field called "QuarterOrPealID" and these are both primary keys, though the field in table B is set to 'no duplicates' and in table A it's set to 'duplicates allowed', as table A has its own auto number/pk. They are both linked in the relationships.
So, when I add a new record to table A using the main form, I might then need to click on the tab in the sub form to create a new record in table B, which has to be linked to the same record in table A. When the "QuarterOrPealID" auto number/pk is generated in the sub form (table B), I need that value to update to the "QuarterOrPealID" field of the main form (table A), so that when I'm viewing these records the form pulls all the information nicely together.

I have my Assets form and the primary key is the ChargerID, in this form I have an "Add New Job For This Asset" button, which opens up the Jobs form at a new record.
How do I make it so that the ChargerID field is automatically filled with whatever the previous record was instead of being blank.
For example if I have Charger12345 open in the Asset form, I'd like to click the Add New Job button and it automatically have Charger12345 in the ChargerID field of the Jobs form.

I have a form where I would like to validate (restrict) choices in subsequent fields.
Example
Combobox choices are Air, Fire, Water, Earth, Space
In the form I have 4 fields = Material1, Material2, Material3, Material4. (all in same record on my table)
Basically I need the validation to not allow duplicates across the 4 fields.
something like....
[Material1] <> [Material2] or [Material3]or [Material4]
I am not sure of the proper syntax for the validation field in the Form Properties. Or if I am even putting it in the right place.

I am creating a training database and first I have tables in relationship to the courses:
tbl_Courses
Course ID (Primary Key)
Course Title
Objectives
Instructors (lookup field allowing multiple instructors to be selected, meaning they are skilled to teach the course)
tbl_Instructors
Instructor ID (Primary Key
Last Name
First Name
Full Name (Caluclated to put Last Name, First Name)
[code]....
What I am trying to do on a form to create a new event is once the user selects the Course from the Course ID combo box, then I need the Instructor combo box to only display the instructors who are skilled to teach the course which are selected in the tbl_Courses.
I can get all Instructor ID's, but not the names and the class that has multiple instructors show on one line.Should I have not put the Instructors field in the tbl_Courses? Do I need another table for instructor skills or something?

I am making a very simple 'registration' database for a children's event in a couple of weeks.I the table/form there is a checkbox field called 'consent' which, if checked, indicates that a child can leave the event without parental consent.
There is a report printed on each child (a registration page which the leaders get a copy of). I would like on this report a 'red box' to appear if the child cannot leave without permission (i.e. the consent box is not checked). I would also like this 'red box' to appear on the form. I had thought of doing it this way - but I'm not sure if it's the best, or if it's possible:
Have a field in my table called 'consentindicator'. When the 'consent' box is checked, there is a period ('.') placed into the 'consentindicator' field. It is set to turn red when a period is present. That way, when the consent box is checked, a get a red 'box'.

Hi All,
Is there a way that I can make a button which will undo all the changes being made on a form (on multiple records). I have a continious form with a checkbox after each record and want to restore the 'old values' if necessary.
Thanks.
I know it's possible by record, but the tricky part is to do this on multiple records.

We have an mdb back end on our server with read / write permissions for several approved users. One of them (don't know who yet) has converted the mdb file from 1997 to 2000. Is there a way to undo this? :o (a few have both versions on their machines which is why this was possible to begin to with)
We have had this set up for almost four years now, with no issues might I add but always knew in the back of my mind something like this would happen.
Thanks
