Forms :: Undo All Changes To Form And Subform?
Sep 25, 2013
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 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 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

I have a form with a subform, on the mainform there is an undo button but when someone makes changes on the subform the undo button wont run and the error message "The command or action Undo isn't available now". How can i get the mainform to detect that changes have been made on the subform and then if the button is clicked undo the changes.

Hi
I have a form and a linked subform which are linked by Purchase Order Number. When items have been delivered on the purchase order, the user should update the continuous subform with the number of items that have been delivered. This works fine.
The problem I have is using an exit button that does not save any of the changes to either the data in the form or the subform. It doesn't matter if there is a prompt to alert the user that there have been changes made.
I have been messing around with DoCmd.RunCommand acCmdUndo in the on click event of my exit button which kind of works when changes has accidentally been made, but is very unsophisticated - any ideas?!
Thanks
Georgina

I have a main form (A) with a subform that is another form with a datasheet(A_SUB)
On the form A is an undo button which rewinds any changes that occur to A that I do not wish to commit. However when I make a change to A_SUB the changes are not rewound. I considered implementing an UNDO for A_SUB but this is messy. What would be a better solution?

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.

I often move sub forms up and down within a form using something like.
Code:
forms!MyMainForm!MySubform.form.top = 500
However, I am having trouble moving a subform within a subform of a form.
Code:
Forms!MyMainForm!!MySubform!MySubformSubForm.form.top = 500

I am attempting to create a Navigation Form to allow another computer in my network to be able to utilize necessary forms within a database (through RunTime). I was hoping this would be a clean task by simply loading the forms into the tabs of the Navigation Form, however that is clearly not the case.
For starters, When attempting to use a form that has some VBA behind it (Docmd.ApplyFilter based on a selection from a combo box), I am given the error stating: "The action or method is invalid because the form or report isn't bound to a table or query."
After searching on this error, I believe it's because my Navigation Form does not have a record source. If this is the case, then I am confused as to what record source it should have, as with the 3 forms I need to access through the Navigation Form all pull data between various tables and queries within the database (some not related).
Now I've also come to the conclusion that my VBA references now must change in order to correctly use my forms. A correct reference would look something like:[Forms]![Navigation Form]![NavigationSubform].[Form].[My Form's Control]..Is this necessary in order to write any events, such as an AfterUpdate on a combo box?

I'm working on the Navigation Form template in Access 2010, which is new to me. It appears that one needs to use the BrowseTo command to open up a form in the built-in subform module. I'm trying to create a couple of buttons where each button opens a form in a different data mode; one in read-only and one in add mode. Here is the syntax I used for read-only:
DoCmd.BrowseTo acBrowseToForm, "frmSales","frmNavigation.NavigationSubform", , ,acFormReadOnly
frmSales is the Sales form I want both of the buttons to open and frmNavigation is the Navigation form. It seems to be ignoring the data mode part at the end however. It only will open in Edit mode. Is there something I'm doing wrong with this command?

Basically I need to design form that looks very similar to either Split Form or Subform. I have attached a print screen of what I roughly need. The form is split into two parts. In the first/top part there are some List Box/Date fields that act as filters to the bottom form, so the bottom form displays only records that match values in red. The second part of the top form has some field that require input from user and then these records are added to the bottom form. I was trying to use both Split Form and Subform and none of it is working,I have attached an example of database and this form would be based on data from Query1.

I tried all sorts of permutations of the requery command but apparently I'm too dense to figure it out.
Form 1
subform 1 > button to open pop up form
subform 2
subform 3
I'm trying to requery a combo box (inside of subform 1) based on a table that is updated from the pop up form.
On pop up form close, what's the correct syntax for re-querying subform 1?

I'm trying to open a form with a subform from a separate form. I've never had any issue before, but all of the sudden, the subform doesn't seem to open immediately. I get the error
Code:
Method 'Form' of object '_SubForm' failed.
After that, it opens (subform and all), but some calculated text fields just say "#Name?#"
The only thing I did today was add a command button to that subform.
When I try opening the form (or subform) from the navigation pane, I get
Code:
The expression On Current you entered as the event property setting produced the following error:
A problem occurred while Contracts was communicating with the OLE server or ActiveX Control
When I step through the code, it doesn't reach the On Current event.

I need to requery a subform from a third form and can't seem to get it to work.
frmForm1 has frmAddress as a subform. The button cmdReviseAddress opens the form frmUpdateAddress where all of my validation work is done and the new record is added.
However, the new address is not being displayed in the subform.
If I use the command
Forms![frmTest]![frmAddress].Requery
it works fine.
The problem is that I want to be able to frmAddress on any form, and need to pass the name of the main form (in this case frmForm1) as a variable.
If lsTemp = "frmForm1", the statement
Forms![lsTemp]![frmAddress].Requery (and every variation using brackets and quotes that I can think of) fails.
Any ideas?
Thanks!

I have a Navigation form that has multiple forms that I linked to buttons at the top. They open the forms (now subforms) for the most part just fine. The issues come into play when I click on a combobox that pulls from a query of a table. Once this data is selected I have another combo box that is supposed to be filtered based off of the original combo box selection. Everything works on the original forms but once they are in subform form I get the error "Forms!MGM Search Form!STATE" which is the name of one of the forms and its asking for me to enter a parameter value for the query. Its almost like its not requerrying the data like it does in the original form
Private Sub State_AfterUpdate()
me.Facility.Requery
End Sub
basically the first combo box is a list of states and then the second combo box is a list of facilities in that state. Once you click on the state in the first combo box it filters the facilities in that state. But again once in the subform view it will not requery.
