I am annoyed because I have done this previously but can't remember. I have an Access database with linked tables to SQL server database and a form which has a sub-form that is populated by a query. The query works as does the sub-form and indeed the sub-form is populated with correct data when the main form is invoked. But I want to stop the sub-form populating on load and only populating with a button click.
I have given the button's "On Click" event an embedded macro to Requery the sub-form and it does seem to refresh the sub-form but how do I stop the sub-form populating on main form load and only populating on the button click
You have several options.
One command way is to remove the "source object" setting of the sub form control. Since the control (a subform control) does not have "pointer" to the sub form, the sub form will not load nor display.
the code to thus set this (behind your button would be this):
Me.MySubFormControl.SourceObject = "tblMain2"
so, just set the source object setting to the sub form you want to display/load.
Be CAREFULL during the form edit WHEN you blank out (remove) the source object setting of the sub form control, often messing during editing will also BLOW OUT the link master and child field settings. They usually stick, but can go away.
The next possible?
In place of setting the source object, you modify the sub form, and REMOVE its data source.
Now in code behind that button, you can go:
me.MySubFormControl.Form.Source = "SELECT * from child table"
Once again, when you do the above, often the link master/child settings can go away. In some cases, you thus can go:
me.MySubFormControl.Form.Source = "SELECT * from childTable where parent_id = " & me!id
Now of course you replace parent_id with the column name used to relate to the parent form.
I think the source object is a better choice, since then not even the sub form is rendered or even loaded when the main form loads.
The only issue is that OFTEN access will attempt to set/change the link master/child settings, so you might consider setting the link master and link child field settings in code also (right before the source object line of code).

I have an Access 2010 database set up with using the native Navigation Form interface feature.
Using this very helpful table, I've been able to use vba on multiple ocassions to reference forms throughout my database. However I seem to be having difficulty in this one instance.
On the Navigation form I have a number of main tabs. Clicking on one of the main tabs brings up a number of sub-tabs that have various forms attached to them.
On one of these sub-tabs, I have a main form (main) attached to it. There is a subform (subform1) within that main form containing a control text box (control1). Within subform1 there is another form (subform2) containing an unbound text box (control2) displaying a value that is calculated using a TempVar.
I want to use the AfterUpdate event on control1 to requery subform2 in order to update the calculation in control2, or simply requery control2.
Using Refresh and/or Requery on the AfterUpdate event for control1 does not do anything to control2.
Currently I have a button on subform2 that users can click which refreshes the form and updates the value in control2. The user can also hit F5 and refresh all the forms with the same result.
My goal is to take away the manual aspect and have the AfterUpdate event for control1 to update control2.
Any help would be much appreciated as I haven't been able to find anything online that works and I've been kicking tires at the problem for over a month now.
**** UPDATE **** I did not correctly describe the layout of my forms. subform1 and subform2 are actually both nested under main. subform2 is NOT nested under subform1 as I originally described above.
Wow. Now I feel like an idiot. Tackling my problem again with the update I provided above allowed me to solve it.
All I needed to do was requery subform2 by referencing it this way:
[Forms]![HOME]![NavigationSubform].[Form]![subform2].[Form].Requery
Where "HOME" is the name of my Navigation Form.
For anyone with the same issue that hasn't renamed their Navigation Form I believe the syntax would be:
[Forms]![Navigation Form]![NavigationSubform].[Form]![subform2].[Form].Requery
Thank you to #Erik von Asmuth and #June7 for your patience and help.
I have a form (called frmMain) with a subform control (called subFrmSub) that is linked to the form frmSub.
frmSub's Default View property is set to Continuous Forms. frmSub contains several controls that the user can tab to.
What I would like to do is when the user tabs to a control in a specific instance of frmSub, that specific instance of the control is highlighted by setting the Border Style property to Solid. No instance of that control from other instances of frmSub should be so highlighted.
I have tried searching for a solution to this problem in the Access context, but even the best ones result in all instances of the control being highlighted.
The best I have come up with is the following code, which also highlights the entire collection of that control rather than the specific one...
Private Sub cmd02_GotFocus()
Me.cmd02.BorderStyle = 1
End Sub
Is it possible to highlight the specific control, and if so, then how? If not, then why not?
Thank you for your time.
I have two sub forms embedded in control (the one that looks like a set of folders allowing you to change from tab to tab.. Sorry I don't know the name in English)..
Both sub forms are embedded on one sheet, I would like that immediately after executing a routine, I wrote on one of the subforms, that the set focus then goes to the other sub form.
For some strange reason I can't get it to work. The sub form and field I'm trying to go to are frmObjectives03 and Effective_date.
I tried:
Forms!frmObjectives03!Effective_date.Form.SetFocus
but it doesn't work.
I would appreciate any insight.
Thank you,
The control you speak of is a Tab control.
Because frmOjective03 is opened as a subform, it is not part of the Forms collection. Instead you can use Forms!MainForm!frmObjectives03.Form!Effective_date.SetFocus from anywhere, or Me!frmObjectives03.Form!Effective_date.SetFocus from within the main form or Me.Parent.Form!frmObjectives03.Form!Effective_date.SetFocus from the sibling subform.
If these are not working for you, please check the name of the subform control in your main form (because it may be Child17 instead of frmOjective03). Open the main form in design view, click on the subform ONCE and look in the Properties->Other->name.
Does microsft office access have this function when i select the row from the subform,
the selected data from EmpName, ComputerName & ProductName will automatically fill into my 2 textbox at the top right and the product Name will be another combobox to select product.
Another thing is, Is it possible to do CRUD upon selection in subform?
what kind of tag should i goggle for to answer my question? I tried a lot of different tags aldy but none answers my question.
The short answer is yes. ;) You can do all those things. I well remember the day I realized that I could do anything in MS Access. (now be kind this was the first experience I had in programming)
You can reference Parent controls from subforms with this convention Me.Parent.control
For example if the Parent form has a text box named txtEmployeeId then on the Click event of a text box in the sub form you could have this code.
Me.Parent.txtEmployeeID = Me.txtEmployeeID
You can quickly extend this code to do whatever you need ie.
Me.Parent.txtComputerName = Me.ComputerName
Me.Parent.cboProductName = Me.ProductName
CRUD is a statement used in web development which seems to be where you are coming from. Access is CRUD in many ways (unless you start getting complicated) In the example above, once you navigate off the parent record with the record selector or close the form, the record is saved without any code being written. Once you start playing around with unbound controls then it becomes necessary to write code to save your work.
I have a form (FORM-A) that requires the user to select a vehicle.
The user should click on a button on FORM-A that say's select vehicle.
A selection form (FORM-B) should open where the user can select a vehicle.
The selected value should be communicated back to FORM-A.
How would you accomplish this in MS Access 2010?
FORM-B is a continuous form that contains a picture of the vehicle and some other information.
From what I understand from your question, you want formB to open a kind of pop-up. When the pop-up is closed, its result is put somehere in the calling form.
Solution proposal:
a) open FormB using syntax docmd.openform "formB", windowmode:=acDialog.
This will prevent execution of the next lines until formB is closed or hidden.
b) in the OK button of FormB, just hide the form, do not close it.
c) when code resumes in formA, you can now
check if formB is still open. If not, it's been cancelled
read the value in hidden formB (still open), then close formB
Otherwise, you could also have formB to update a control in formA before closing. But I don't like that approach because then formB is not reusable, and it creates an unnecessary dependency between formB and formA.
I am not sure why you would need a separate form for this - just have the first textbox be a listing of all the records of vehicles in the database, where you would select one, and the rest of the vehicle information is auto-populated from the vehicle table, but not copied into your parent table. Of course, I am not sure of your table structure either, so there might be a reason for this method that isn't apparent to me.
The benefits of the method above is that if you add more vehicles, your selection box is automatically updated - and you keep the forms you have to load to a minimum (always a good performance move)
You can reference the forms in this manner forms!formName!controlName.
Once you see how this works you will be able to fool with it to get it working with your existing setup. Let’s use 3 controls a text box on Form-A, an image on Form-B and a text box on Form-B. The text box on Form-A will be named txtVehicle, the image on Form-B will be named imgVehicle and the text box on Form-B will be named txtVehicleName.
You can set the name of a control within properties. When you click on imgVehicle it will put the value from txtVehicleName into txtVehicle.
You will have to do a little coding - it's easy though if you have not done it before. Under properties for the image you will see events. If you click on the "On Click" event you will get a drop down list. One of the choices will be [Event Procedure] - choose that. A little button with 3 dots on it will also show up at the end of the row. Click it and you should be taken to a code window with some code like this in it.
Private Sub imgVehicle_Click()
End Sub
Here is where you put your code. Something like this should work. This is it in its most simplistic form.
Private Sub imgVehicle_Click()
Forms!Form-A!txtVehicle=forms!Form-B!txtVehicleName
End Sub
Now although that will work, there are a few things that we should be doing in this method that we are not. We should reference Form-B directly since we are in it, we should verify that Form-A is in fact open.
Private Sub imgVehicle_Click()
If currentproject.allforms(“Form-A”).isloaded then
Forms!Form-A!txtVehicle=me!txtVehicleName
End if
End Sub
Hope that helps
You can create an instance of formB within formA and control it. Below is the VBA code for formA. When clicking on a button on formA, you create a new instance of formB and give it focus. At the same time, you can set properties for its controls. You can use this approach to set the right picture in your control on form B. Hope this helps.
Example:
Option Compare Database
Dim fB As Form_FormB
Private Sub btnA_Click()
Set fB = New Form_FormB
fB.SetFocus
fB.tbxB.Text = "Some text sent from A to B!"
End Sub
If you want both forms to be visible all the time, I suggest using a subform with the list of all the vehicles or just details for the one that the user selected.
