My goal is to change the SourceObject of a subform. I can do this manually by going into design view selecting the subform object and changing SourceObject and removing the master and child links. I save changes and reload into form view and all works well.
When I try doing this via VBA it does not seem to work and gives me a blank subform.
Here is the code that I am currently running:
Private Sub ondacapBtn_Click()
Me!DACAPRosterQ_subform.SourceObject = "ondacap_subform"
Me!DACAPRosterQ_subform.LinkMasterFields = ""
Me!DACAPRosterQ_subform.LinkChildFields = ""
Me!DACAPRosterQ_subform.Requery
I find this even crazier because this is code I've used before except the Me!subform is a different name, and it works perfectly elsewhere! I am complete baffled at how this works in the other subform but not this one.
I've tried changing the name, the tab order, made sure the subform I am changing to works, made sure the code matches the other subform shown below, I am out of ideas and I made this account just so I can ask this question. It's really upsetting me.
Private Sub FilterBtn_Click()
Me!Retrain_subform.SourceObject = "UpcomingRetrain_subform"
Me!Retrain_subform.LinkMasterFields = ""
Me!Retrain_subform.LinkChildFields = ""
Me!Retrain_subform.Requery
EDIT - 26SEP22
I found out that one of the fields in my RecordSource is causing this issue.
My subform has a RecordSource called DACAPRosterQ and in that query I've input a field that is called "SearchTerms:" [with] & [other fields] & [listed] & [to use as search bar criteria]. The table PersonnelT that the query DACAPRosterQ pulls from does not have the "SearchTerms:" field naturally. Only the query.
When I remove this field from the query the subform can be switched with no issue via VBA.
Something I noticed when trying to open Ondacap_subform individually without the parent form is it asks for input "Forms!DACAPRosterF!DummySearchTextbox" which is a control on the parent form DACAPRosterF alongside the subform.
I have a feeling I must input some code to reinitialize that field as it is not done so via VBA. I'm just not sure what it is.
I think this would also explain why I am able to switch SourceObject manually via design view because it it already being reinitialized when reopening the form in form view.
Anyone have any ideas?
I figured it out... I couldn't tell you why it works or why it didn't work without this solution.
All I had to do was enter into the subforms OrderBy property, I ordered it by [Field1], [Field2]. Works like a charm now. Search bar still works and everything functions as normal.
If anyone could provide insight as to why this occurred, that would be amazing. Otherwise, problem is fixed.

I'm trying to optimize the performance of my access frontend. One of the problems I'm stumbling on is how to set a multi-window form to open immediately to a specific record, because at the moment it queries everything twice.
Essentially, I allow my users to open multiple instances of a form. That way, a user can compare multiple records by placing the windows of those forms side by side.
At the moment, my code looks like this:
Set frm = New Form_Name
frm.RecordSource = "select * from Table where id = " & ID 'ID is a variable passed to the method
I'm pretty sure back then this question was one of the building blocks I relied on.
The problem is that on the first line, access already entirely opens the form and does everything the form does when opening, such as Form_Open, Form_Current, and loading subforms. Then, when I set the recordsource, it does all (or most) of that again, which significantly slows down the process of opening the form.
Here are some of the things I've tried:
Changing the Form_Current to recognize that it's being "used" twice and only actually run the code once. The problem is that the code is already very optimized and doesn't seem to be the bottleneck, so this doesn't seem to do much. Actually opening the form seems to be the bottleneck.
Trying to change the properties of the original form so that it opens the specific record I need, but I can't seem to change the properties without it opening the form.
Looking for a way to supply arguments to the form. That doesn't seem to be supported in VBA.
One other idea that popped into my mind was creating a variable in vba with the ID of the record, setting recordsource in the form properties to fetch that variable, but then, when I would open another form and change that ID, the form
I realize that I can do this with DoCmd.OpenForm, but that doesn't give me the option to open multiple instances of the same form.
How can I achieve this? This would mean a significant performance improvement.
OK, so I actually wanted to ask this question. But just before I hit the submit button, I had an idea...
Here's the idea: you set a global variable in VBA, which you then access in the form filter command. In my case I just added Public OpeningID As Long at the top of my VBA module. Then I create a function to get that value:
Public Function getFormID() As Long
getFormID = OpeningID
End Function
Then, in the form, you can set the filter criteria as ID = getFormID(). And then when you open the form instance, you do it like this:
OpeningID = ID
Set frm = New Form_Name
OpenindID = 0 'reset this to make sure that if it's being accessed when it shouldn't, it generates a clear error
The only problem is what happens when you refresh the form, as that will call the method again. When you refresh the form via VBA, you can set the OpeningID beforehand, and to avoid users refreshing the form, you can add this to your form (don't forget to turn on Key Previews in the form settings):
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = vbKeyF5 Then KeyCode = 0
End Sub
Bang. Forms open almost twice as fast. Awesome.
I have a form frmDetail that contains several locked fields I want populated only when another form has been filled out, in the name of having some kind of standardization in my data. This other form frmSignOut is used to enter in a date and location that will populate the fields on frmDetail. frmSignOut also contains a subform subULookup that looks up users from a different table using an identifier number. The resulting last name, first name and phone # should also be passed to frmDetail. I also hope to combine first and last name somehow into a Last,First format.
My approach so far has been to open frmSignOut modally with acDialog and I inserted Visible=False into the On_Click event on frmSignOut. Then I try to reference my subform fields and set them to the desired fields on frmDetail. I finish by refreshing and then closing the dialog form.
Private Sub CmdSignOut_Click()
DoCmd.OpenForm("frmSignOut"),,,,,acDialog
If CurrentProject.AllForms("frmSignOut").isLoaded=True Then
Set Forms!frmSignOut!SubULookup.PhoneNbrTxt=Me.ContactNbrTxt
DoCmd.Close (acForm), ("frmSignOut")
Me.Refresh
End If
End Sub
I have only been able to get this far, trying to pull the first field PhoneNbrTxt. I can get frmSignOut to open, I put in data and when I click my 'close' command button I get run-time error 438: Object doesn't support this property or method.
The line highlighted is where I try to reference my subform field. I also have a 'Cancel' button added to frmSignOut that just closes the form, I have no errors there.
Again I'm completely new to Access without much prior experience in anything related, I'd appreciate any knowledge you guys can throw at me.
EDIT: I've been able to successfully pull the value to Me.ContactNbrTxt by adjusting my code to the below.
Me.ContactNbrTxt = Forms!FrmSignOut!SubULookup.Form!PhoneNbrTxt
It looks like the missing part was the Form! right before the control name, along with formatting this correctly and dropping Set.
Im still trying to work out how to combine first and last name before also pulling those to frmDetail, if anyone can help there.
Please help me explain, why this happens, after that the solution should be easy :)
I have two forms, showing different data.
Form_1: there is a combo box (with names in it), where you can choose which company you wanna see, and an after-update macro searches the record (an [ID] field), and shows the information. (To be more complicated, this [ID] field is hidden, and used for subforms, where the actual infos appear.)
Form_2: this is a continuous form, each record is in connection with the companies shown in Form_1, but several record can belong to one company. There is a button for every record to open Form_1 with the information connected to it. The vba code of the button is:
Private Sub Button_Click()
DoCmd.OpenForm "Form_1", , , "[ID] = " & Me![ID]
End Sub
In the code, the same [ID] field is used, as described above: hidden and used for subforms.
Both forms are working as needed, I am happy with them.
But after Form_1 is opened from Form_2 with the button, the combo box remains empty (actually I don't need it to be filled), and if I wanna use it to search for other items, it doesn't work, as if the macro wasn't loaded. The list of names appear, I can click on any of them, but the [ID] field is not refreshed (and of course neither the subforms). I have to close the form, and open it again from the side-list.
Why does the macro stop working?
What should I change, to make it work?
Thanks for your help!
Form1 has the filter turned on to a specific key value, so attempts to find and reposition the form's current record will fail without explicitly resetting the filter.
The Where condition of the OpenForm command does not change the form's Record Source property, nor does it perform a simple search/reposition. Rather, it applies a form filter:
DoCmd.OpenForm "Form_1", , , "[ID] = " & Me![ID]
This state is indicated in several ways
On the Home ribbon (i.e. toolbar): The Toggle Filter button is active... is highlighted by a different color.
The form's navigation bar at the bottom of the form show "Filtered" highlighted with a little funnel icon.
The Access status bar shows "Filtered" on the right near other indicators.
Of course it's possible that all of those indicators are hidden, so you just need to be aware of what each command and parameter does.
Possible solutions:
Form1's ComboBox.AfterUpdate macro should turn off the filter before searching for a new ID value.
Form2's Button_Click event opens the form without applying a filter and instead runs code that does the same thing as the ComboBox.AfterUpdate method--searches and repositions the form's record rather than filtering it.
This can be achieved in multiple ways and is largely beyond the scope of this answer, but a hint is to make a Public method in the Form1 module that performs the search. Both the ComboBox.AfterUpdate method and the other button call that same public method so they have the same behavior.
I inherited a fairly large project at work that is undocumented and written in VB (originally started pre .NET, ended around .NET 2). I'm in the process of updating / refreshing a lot of the code, but have run into an annoying issue that I haven't found the solution for yet. This system utilizes a UI, a Web Service, and a SQL DB.
Problem: I have a Databound Combobox (originally set to DropDownList - I'm changing it to DropDown, which is what started this mess - going back isn't an option) that is tied to a DataSet that comes from a Web Service. When a user types in the item they want manually, the data from the text field doesn't seem to associate itself with the DisplayMember, which forces the WS/SQL query to fail (it is sent a blank value when it's expecting a ValueMember). If the user types in a partial selection and then chooses the value they want from the DisplayMember list using the arrow keys or tab, the query goes off without a problem.
My Question: How do I get the text field to translate to the DisplayMember which will then properly tie itself to the ValueMember which will then allow the query to execute correctly? Sorry for making this sound complicated or convoluted; I'm sure the answer is easy and I'm just glazing over it.
The relevant bit of code is:
With cmbDID
If dtsLU.Tables.Contains(reqTable) = True Then
.DataSource = dtsLU.Tables(reqTable)
.DisplayMember = "zip"
.ValueMember = "gridID"
End If
End With
cmbDID.DataBindings.Clear()
cmbDID.DataBindings.Add("SelectedValue", dtsData, strDT & ".gridID")
I've tried changing "SelectedValue" to "Text", which almost works - but it directly translates to gridID and skips zip which ends up with an incorrect Web Service response since the zip and gridID field values are not synced (zip (DisplayMember) may be 5123 while gridID (ValueMember) may be 6047). I've tried changing "SelectedValue" to "SelectedIndex", and that got me no where.
Any help is greatly appreciated.
EDIT
To add some clarification to the process, the below pseudo code / description is roughly what happens. I could post the whole module, but I feel that would just muddy the whole question even more.
Private Sub A
FormAlpha is created with 1 ComboBox in the form of a DropDown
This DropDown is populated with a DataSet
DataBinding with a blank DataSet is added to the control to keep track of the users input
End Sub
lblSubmit_Click event is triggered on FormAlpha by the user after they have populated the DropDown with their data. lblSubmit_Click calls Private Sub Submit
Private Sub Submit
BindingContext(DropDown DataSet, tableName).EndCurrentEdit() is called
DataSet.HasChanges() is processed
If changes are present, changes are processed
HERE lies the problem
If the user has manually typed in the DropDown field, but not hit an arrow key or tab, then the DataSet registers a change, but returns a null value in all fields - it knows something was entered, but that data apparently didn't pass through the DataSet for the ComboBox (ListItems or SelectedIndex didn't change / fire I'm guessing). If the user selects the item with the arrow keys, the DataSet has the proper input (I'm assuming the Data was validated by the control at this point).
If the processed data is good, a value is entered into the database
If the processed data is bad (empty), an error is returned
End Sub
If the above can't be solved with what I've provided, but someone still knows a better way to handle this type of situation, I'm all ears. Rewriting the module isn't ideal, but fixing this problem is a necessity.
Alright, while this fix may not be ideal, it is a fix none the less.
The bare bones problem was that the text value of the DropDown wasn't causing the data to actually affect the SelectedIndex / SelectedValue of the control unless you interacted with it using the arrow keys or a mouse click. So, while the DropDown would read "1234", in reality the control saw "".
The fix I have in place for this is simply calling comboBox.text = comboBox.text whenever the user hits the submit button.
I have a Form that contains several subforms. On one of the subforms, I need to run an update query if you click off to another subform (you finished with the controls, if anything changed it must update). This part works great. The trouble I am having is I don't want to bog everything down by running the update (its a loop of update queries) every time you click on any subform.
If you are on a very specific subform (PageIndex 2) then it should run the updates. Below is the code I have to determine which tab/page/subform I am on. PlanSpecs is the name of the Page.
The problem is that no matter what tab I am current on, if always says "I'm on that subform." Any idea why that might be, or any suggestions as to what I can do instead?
If (Me.PlanSpecs.PageIndex = 2) Then
MsgBox ("I'm on that subform")
Else
MsgBox ("Different Subform, move along")
End If
I don't think you can refer to them by that index, unless they're in a tab control, then you'd have the PageIndex property.
You can however do it like this,
If (Screen.ActiveControl.Parent.Name = "SubFormNameHere") Then
MsgBox ("I'm on that subform")
Else
MsgBox ("Different Subform, move along")
End If
But this code may need additional conditions, for instance if you add a tab control to that subform, then it'll return the name of the TabControl and not the parent(form).
