Problem Updating Main Form Control From Subform In Access 2003 Project (ADP)
Nov 30, 2005
I'm supporting some Access/VBA code which includes the following behavior:
When an update is made in a (linked) child form, the current date/time is written to a textbox on the main form via
Me.Parent!txtMod = Now
Likewise, the BeforeUpdate event of the main form updates the same field (and then does a bunch of form validity checks, possibly followed by a Save).
When we upgraded to Access 2003 from Access 2000, a problem erupted:
When the user returns to the main form (by clicking on any control outside the subform), the following message is issued: "This record has been changed by another user since you started editing it (etc.)..."
At this point the user must choose between "Save Record", "Copy to Clipboard" and "Drop Changes".
Conceptually, I see why this is happening (though I wonder why Access 2000 didn't flag it). The subform is the "other user". When the main form is returned to, it is "Dirty" (unsaved update), so the main form's BeforeUpdate event fires, and attempts to update the field again (Me.txtMod = Now). Since there is a pending change to the field, an error dialog pops up.
As a quick fix, I replaced the code in the subform with a flag ("Hey, I've been updated!"), which the main form checks on the Exit event of the subform control. But that seems a horrible solution. Surely there's a better way?
Notes:
1. It would be preferable to have the timestamp updated right away by the subform, though having it updated when the subform loses focus is better than nothing.
2. Since a subform is a control from the main form's perspective, I'm surprised that a change to that control doesn't render the main form "Dirty". I guess from a database standpoint it makes sense (the form's table isn't getting updated at all; just the subform's). But then, how does the main form know that the subform has been updated?
3. I tried catching the error via Form_Error. I can make the dialog not appear via "Response = acDataErrContinue", but unfortunately it defaults to dropping the changes (old and new), rather than saving the new.

Lets say I have Form A and Subform A with the parent-child relationship established that works well. Subform A has a Text box control that is getting display when I include the subform in Form A.
Now, I decided I dont want to include subform A in the Form A. Is there a way for me to show the contents of that Text box control in Form A without attaching the subform in the main form (Form A)?
I read somewhere that to refer a control on a subform, I have to use the code - Forms!mainform!subform.form!control. But this would be in VBA. What is the equivalent of this in a Control Source in the main form?
If I have not explained myself correctly, please do let me know.
To summarize, my question is without including the subform, I want to reference the values of the subform in the mainform. (I have some design necessity for this requirement) Is there a way for this?
thanks!

Hi,
Mainform and Subform are linked on field "barcode".
Barcode is the primary key for the table that Mainform is based on.
When user is entering a new record, I have the BeforeUpdate event of Mainform.barcode set to check to see if the barcode already exists in the table, and if so, to give the user some meaningful error message.
Works fine, except that the subform still updates to match the invalid, previously-used barcode. I want the subform to stay blank until the user has entered valid data in MainForm.
How do I accomplish this?
Thanks for any ideas.

Hi, I have a problem I don't know how to solve it. I have a subform in datasheet view, linked to the main form. There is a running total on the main form based on a dsum on a field of the subform.
When I delete a row on the subform datasheet, the main form calculation is not automatically updated. I had to create a "update" button to do the refresh.
Is there a "on record delete" event available for a datasheet sub form?
Thank you for any help.

I have a navigation tab with 6 sections, of the 6, 5 of them are self-made split view with a form view on top and datasheet on bottom and upon adding records through a command button on form view I would like the datasheets to update.
On other forms it would (I believe) update to the bottom of the datasheet, now on the ones I've been banging my head against it either replaces the top record or doesn't show up unless I switch tabs and switch back. From my searches I assume this is in need of a requery...

Within my main form I have a combo box called "workgroup." Also in the main form is a subform called "sfrmSubmissionRecords," and within this subform is a combo box called "covermemo."
Each cover memo is assigned to a specific workgroup, so my intention is for each time a new workgroup is selected from the dropdown, the covermemo combo box in the subform becomes populated only with the covermemos associated with that workgroup. I'm almost finished except for the final step when I try to make the values regenerate...Access says that can't find the referenced form "sfrmSubmissionRecords"
This is the code that I'm using:
Private Sub cmbWorkgroup_AfterUpdate()
Forms![sfrmSubmissionRecords]![cmbCovermemo].Requery
End Sub

Ok, this is what I have:
I have setup my main form with 2 subforms to mimic a split form; this works fine.
To search for a record, I am using a cbo on the main form which I would like the user to select from. Once selected, then this will populate the first subform.
This is the code I have for the cbo:
Dim intAnswer As Integer
If IsNull(Me!cboCaseNoCFDWit) Then Exit Sub
With Me!sfFocus.Form.RecordsetClone
.FindFirst "Me!sfFocus.Form!CaseNumber = """ & Me!cboCaseNoCFDWit & """"
If Not .NoMatch Then
If Me.Dirty Then Me.Dirty = False
[Code] ....
I get an error at the .findfirst; states that the Microsoft Engine does not recogize Me!sfFocus.Form!CaseNumber
And the reason I am not using a regular split form is because I cannot, get the form to the size that I want. The splitform works great with the code above (a few changes to it of course), but the bottom of the splitform (datasheet) is too long and I cannot shorten it.

I have a Main form 'frmEmployeeInjury' with a subform 'frmInjuryDetails'.On the subform is a date field 'dteDateofInjury' and on the main form a command button 'SaveRecord'
What I am trying to do is hide the command button on the main form until a date is entered in the 'dteDateofInjury' field.I have looked online and found information on main form and subform referencing, but I can't follow it very well without examples.
Code:
Private Sub dteDateofInjury_AfterUpdate()
Me.Forms![frmEmployeeInjury]![SaveRecord].Enabled
'Me.Parent.cmdSaveNewInjury.Visable
'Me.Parent.cmdSaveNewInjury.Enabled
End Sub
But I get 'method or data member not found'.

I'm using form with subform. Main form header contain a combobox. I need to check the combobox is null or not before update a subform filed. If combobox is null then its back to Main form combobox from subform. The code below that I'm trying to:
Code:
Private Sub AssignTo_BeforeUpdate(Cancel As Integer)
If IsNull(Forms!frmDepartmentReview!cboDepartment) Then
MsgBox "You must select Department first", vbInformation
Forms![frmDepartmentReview]![cboDepartment].SetFocus
End If
End Sub
Then I'm getting 2110 run time error
Access can't move the focus to the control cboDepartment.

I have a form with a subform which resides in a tabbed control. In that subform, I have a textbox in the footer that sums values in the detail section of the subform.
I have a textbox on my main form that should display the same data that is in my subform footer textbox, but it is giving me the #name? error.
This is the expression in my subform footer textbox (which returns the correct result):
TxtSubtotalHQPCalc -
=Sum([ActualHQPCalc])
And the expression in my main form textbox (which returns #name?):
txtActualHQPValue -
=([subfrmHQPProject].[Form]![TxtSubtotalHQPCalc])
I have verified that my subform name and textbox names are all accurate. This is very frustrating because I am using this exact same method in a different database with no problems!

I have a form called Add New Delegation, i have combo box of Institution names on the main form and a subform for Agreements discussed. with a combo box called agreements. I successfully cascaded the combo boxes so that the agreements discussed on the subform are filtered by their respective institutions on the main form. However i am unable to refresh the list each time a new institution is selected as the Macro will not allow me to requery a control on the mainform from the subform..

I believe I did this before awhile ago but for some reason I keep getting an error.
I have a Mainform (frmMain) that has a Subform (frmSub). On frmSub I have 2 comboxes (strCom1 & strCom2) one is set to invisible (strCom2.Visible = No).
So using the "On Open Event" of frmMain I want make strCom2 visible if strCom1 = "Read Only". Ofcourse I will also need to place the vba on the On After Update event. Below is what I have so far but doesnt work.
I get Run-time Error 2427 "You enetered an experssion that has no value"
Code:
Private Sub Form_Open(Cancel As Integer)
If Me!frmSub.Form!strCom1.Value = "Read Only" Then
Me!frmSub.Form!strCom2.Visible = True
Else
Me!frmSub.Form!strCom2.Visible = False
End If
End Sub

Hopefully this is pretty simple.
Have an existing app. When I open it from within Access the app seems to go into some runtime mode ... shows a splash screen, menus, etc.
Okay how do I go into design mode so I can modify it ?
Yeap am a complete newbie with Access and haven't touch since the Office 97 version :o:eek:
Not sure if you are meant to ask multi questions in one thread, or create a thread for each one. Will created a new thread for my other question, so if one of the Mods could point out the correct way of doing this would be appreciated.

Hello,
I have two questions related to deplying an Access project I have been working on.
1. I started developing the project in Access 2000, but midway upgraded to Office 2003 and so the remainder of the project has been developed in Access 2003. Things seem to be fine, except that in the top most title bar, after the project name, there appears the following text:
xxxxx: Database (Access 2000 file format)
where xxxx is the name of the .mdb file.
Why is this appearing and should I have done something or do something to make it a Access 2003 format?
2. I am at the point of deplying the db to a small group of users (about 5). Some of them may have Access 2000 or Access 2002. Should I be doing something in particular to make sure things work in their machines.
Any pointers to what may be problems or what I should do will be much appreciated.
Thank you.

I have a main form and a subform.
Both forms have the field called JobID in common.
Both forms have a field called JobStatus.
Any easiest solution so that After I Update the field called JobStatus in the subform, it changes the field called JobStatus in the main form to the value which was selected from the subform?.

Hey Everyone,
I am stuck trying to figure out this problem. I have a main form "frm_tirelog_600" which has 4 combo boxes "cboleg",
"cbocar", "cbopos", "cboserial" on it. The first 3 combo boxes are used as criteria on 1 of 3 subforms that I have.
The fourth combo box "cboserial" is used for the criteria in a query on another subform that I have called "frm_mount_600_subform",
which is independant from the main form, I hope I have explained that clearly enough. What I need to be able to do is
have the subform fill in 3 of the fields on it "leg", "car", "pos" with the value from the 3 combo boxes on my main form. I
can get it to show in the fields but not write to the table. I have searched the forum and have not been able to locate anything
that would work and really need any assistance with this. Im not real strong in the coding department which is where I
beleive this could be done.
I have attached a copy of my DB which I hope will better explain it. Any help would be greatly appreciated

I have a subform which makes a change to a field on the main form. When focus is returned to the main form, the BeforeUpdate and AfterUpdate events fire. Why? I thought from the form's perspective, the subform is just another control.
BTW, I get the same behavior if I modify the field from within the Exit event of the subform control.
In either case, the main form's Dirty event is NOT triggered.

I am using MS Access 2010, I have three tables,
Policies (Id, Client Id, Address, Policy Amount, Paid)
Payments (Id, Client Id, Total Amount)
Payment Details (Payment Id, Policy Id, Paid Amount)
I have created a form "PAYMENTS" that include a sub form "PAYMENT DETAILS".
In the sub form control Policy Id is defined as combo box, and retrieving the list from Policies and Payments where Policies.Client=Payments.Client the query of Combo Box is as follows:
Code:
SELECT POLICIES.[POLICY ID]
FROM POLICIES
WHERE (((POLICIES.PAID)=False) AND ((POLICIES.CLIENT)=[Forms]![PAYMENTS]![ClientId]));
Only first time Combo Box display the Policy Ids according to the Client, but when I change the client and always displays the previous clients Policy Ids.
how to retrieve correct list of Policy Ids according to the Input Client in Payments.Client control

Here's the issue: I have a main form with a subform on it. The main form's record source is called "tblMainForm" with one field in it-MainFormPK-the primary key. The subform's record source is another table called "tblSubform" and it has three fields-SubformPK (the primary key), MainFormPK (foreign key) and DataEntry-a standard text field.
I want to create a new record so I open the main form and am immediately brought to the subform's text box whose control source is DataEntry. I enter something into the text box and close the form. What I entered into the text box is saved in tblSubform but the main form did not create a new record therefore MainFormPK was not automatically entered as the foreign key in tblSubform and there is no link between the forms. (By the way, the Master and Child fields are set properly.)
My question: Is it mandatory that the main form containing a subform have a data entry field? If not, does anyone know of a way around it? Thanks for any help.

I have a main form that has two subforms, subform1 and subform2, both connected to the main form. When I enter data into a field in subform1 I want subform2 to requery and update to show the calculated results from the new or changed data in subform1.
I found that if I do a refresh it works when changing the data but not when entering a new line of data in subform1. I tried some code in the after update field of on subform1, but cannot seem to get anything to work.
Me.[subform2].Form.Requery
Does not work. It errors and says it cannot recognize subform2 as a field. I have tried a field name on subform2 but I still got the same error.

I am working on a massave aplication that has been running in Access 2000, but recently several of the file sharing users have installed Access 2003 because of the limited availability of Access 2000. All the users are using the same file off the server.
The problem we are having is that when we reference a subform in the "[Forms]![FormName]![SubformName]![FeildName]" Access 2003 does not recognize it and returns an error. I have found that if I will modify it to "[Forms]![FormName]![SubformName].[Form]![FeildName]" it is recognized in both 2000 and 2003.
To try and change every instance of a subform reference will take forever and I am garuteed to overlook something. We reference subforms all over our program, missing any one of them would be a disaster. Before I went to the tedious task of looking through everything I just wanted to throw the situation out there and see if any of you had any great ideas on how to get it fixed efficiently. I would apreciate any ideas.

I'm working on a database that is quite large. I foreign key that connect all the table is project_id. When I start a new project there a certain table that will not be used for quite some time. I would like them updated when I start the project with the same autonumber that is created for the project table.
There is an input section to add to the project and a view section to navigate through to view all sections of the project ir budget, financing, schedule. The navigate function wont work properly unless I have all project_id's updated.
Any ideas
