I'm trying to implement a very simple subform document grid on a form:
I have everything except getting the file path when the user clicks the grid. How can I get the filepath value from the user row click event ?
Sorry if my terminology is off I rarely write vba
You can create a public subroutine that references your FilePath field and then reference this subroutine in the on-click event of each of the fields on your subform.
So if your subform looks like this:
Go in to Design View of the form, and select one of your fields:
With a field selected, go to the Property Sheet on the right-hand side and go to the Event tab and click the [...] button on the On Click event:
You'll be taken to the form's VBA script module and it'll create the initial VBA for the on-click event of the field you selected:
Ignore that field's on-click event VBA for now, and instead move your cursor to the top and make some room for a public subroutine above the field's on-click event.
Write something like this at the top:
Public Sub GetFilePath()
Debug.Print Me.FilePath
End Sub
So your code in Access should now look something like this:
That public sub I've called GetFilePath can now be referenced in the on-click event of every field in your subform. Let's finish the on-click event of the ID field that we just started...
...and also reference the same public sub in every other field's on-click event (again, by selecting the field in Design View and then clicking [...] button in Property Sheet's on-click event):
In the VBA editor, make sure you have the Immediate Window open; it should be in the area below your VBA code. If it's not there press Ctrl + G or go to View > Immediate Window:
With the VBA editor and Immediate Window still open, go back to your form and put it into Form View.
Click on any row and you should see the FilePath data for the row you've clicked on print out in the Immediate Window (this is what Debug.Print does):
You probably don't want the FilePath to go the Immediate Window, but as you haven't specified where you want it to go I figured this would at least illustrate how you can get at that data by clicking on a record in your subform.
All you need to do is replace the Debug.Print Me.FilePath line to whatever is useful to you.
Hope this was enough to get you started though :)
MS Access does not provide Row click event. You have to either perform, [Form onClick Event] or ideally make the filePath as HyperLink and onClicking FilePath retrieve its value.
When you go for [Form onClick event] you will get the FilePath from selected row. But the click event is only fired if you are clicking the form and none of the fields.
As above mentioned, make the FilePAth field as hyperlink, add onClick event to it and retrieve the value.
sorry for upwarming but the accepted answer is not the best way to go.
Instead of creating an OnClick-event for every column in that subform (for each control),
you should rather use the OnCurrent event of the Subform itself, which is triggered whenever you change the current record. This basically happens whenever you click on another row in the subform.
Doing so will save you work whenever you extend the subform with a new column.
in that OnCurrent Event of the Subform you will then have the same code.
Basically it should look like this:
Public Sub Form_Current()
Debug.Print Me.FilePath
End Sub

I'm creating a form in MS Access with 10 butons simulatin a numeric keypad (only the values 0..9).
I would like to change the value of a combobox control in a subform each time I click on one of these butons. The combo box control is named "projectID"
I tried this but it is not the same as pressing the same key on a keypad.
Private Sub Buton3_Click()
Call Me.frmServDedicacion_Subformulario.Form.projectID_KeyPress(51) 'Ansii code for 3
end sub
I put this procedure as keypress event in order to verifiy the combobox method is executed, and it does (msgbox is ok) but the combobox doesn't receive the KeyAscii value.
Public Sub projectID_KeyPress(KeyAscii As Integer)
MsgBox Chr(KeyAscii)
End Sub
This looks like a problem referring to a control on a sub form from the main form. I still have trouble getting this right so I use a cheat sheet:
http://access.mvps.org/access/forms/frm0031.htm
I created a main form called main and put 10 buttons named button0 - button9 on the form and I dragged a form called mysubform onto the main form to create a subform. mysubform has a textbox named projectID. Then just set the click event to button0 to:
Private Sub button0_Click()
Me!mysubform.Form!projectID = 0
End Sub
Don't forget similar click events for buttons 1-9
some things that may be helpful:
! is the bang operator see:
Bang Notation and Dot Notation in VBA and MS-Access
by default, when you drag a form to create a subform control on another form, access gives the subform control the same name as the dragged form. so here mysubform refers to the subform control and not the original form used to make the subform.
Then .Form gets the form wrapped by the subform control.
I hope this answers your question
Imagine a form that, for demontration purposes, contains only a subform and a textbox that need to mirror each other.
I tried to accomplish this by setting the Control Source on the textbox to the value of the field in the subform and this worked to make them mirror each other, but the textbox isn't editable so this is an unsuitable solution.
The next thing I decided to try was using the AfterUpdate event on both controls to run code that sets the value of the other control.
This is easy for the textbox:
'Set value of Notes field on subform whenever value of the corresponding textbox
Private Sub Notes_Textbox_AfterUpdate()
Me.subform.Form![Notes] = Me.Notes_Textbox.Text
End Sub
However, this isn't as simple for the subform field. I don't know how to reference an event on a field in a subform in a way that will still allow me to reference controls outside that subform.
As a demonstration, I need a way to do this:
Private Sub subform_Notes_AfterUpdate()
Me.Notes_Textbox.Text = Me.subform.Form![Notes]
End Sub
I can access the subform fields AfterUpdate event within the scope of the subform but if I do that, then I can't access the Textbox because it is in the main form, not the subform.
So I either need a way to define an event function on a field in a subform from within the scope of the main form, or a way to make the textbox part of the subform while maintaining the subforms ability to open in datasheet view.
Not sure I get the whole problem (how does datasheet view come into play?), but this should do what you want:
(in the subform)
Private Sub Notes_AfterUpdate()
Me.Parent!Notes_Textbox.Value = Me![Notes].Value
End Sub
Edit from comment: By far the easiest solution would be a continuous form instead of a datasheet in a subform.
You can have two textboxes, a one-liner in the Details section, and a large one in the form header or footer. Both have the same control source and are automatically updated when the other one is edited. No code required.
If it must be a subform-datasheet, you can use a similar approach: bind the main form to the same recordsource, and in On Current of the subform, move the main form to the same current record.
Hopefully I can explain what I want to do well enough...here it goes...
I have a data entry form...the user will be entering employeeIDs. Once in normal operation, most people will be entering only their own EmpID, and they should know it, so this won't be a big problem 99% of the time once this DB goes live.
However, I need some temps to enter historical data from paper sheets into the DB. These people will not know anyone else's EmpID. I'd like to set the Student field's OnDblClick event in the subform's datasheet to open a small form with a combo box. The combo box has a list of all Employee Names, and is bound to the EmpID. Once this user enters the name, and selects the person, I have a button they can click to return to the datasheet.
I can use a function to launch the form, no problem there. But how do I return the EmpID to the field in the datasheet that was double clicked?
When user double clicks in the Student field...I want the next form to appear, and then once they type in the name and select the correct person...and then click Found Them!...I need that bound value to return.
I'd love to say I have code to share right now...but the only code I have is to launch the look up form. I'm brain farting on how to pull the value back down.
The way to do this to launch your little dialog form as “acDialog”. This will cause the calling code to WAIT.
And then the “magic” part is when they click on “Found Them” you do NOT close the popup form, but simply set the form’s visible = false. This has the effect of the calling code that popped up this form that halted to continue (the form is kicked out of dialog mode when you do this). So now your calling code continues.
So your code will look like this:
Dim strF As String ' name of popup form
strF = "frmPopUp"
' open form, wait for user selection
DoCmd.OpenForm strF, , , , , acDialog
' if for is NOT open, then assume user hit cancel buttion
' (you should likly have a cancel button on the form - that cancel buttion will
' execute a docmd.close
If CurrentProject.AllForms(strF).IsLoaded = True Then
' grab the value of thee combbo box
strComboBoxValue = Forms(strF)!NameOfComboBox
DoCmd.Close acForm, strF
End If
As noted, the code behind the Found Them button DOES NOT do a close form, but sets forms visible = false (me.Visible = false), and this trick allows the calling code to continue at which point you can examine any value on the form. Remember to then close the form after you grab the value.
It looks like your data table is in a subform so there is a little more work but it does not have to be as complex as the above solution if you don't want it to be. #Andre451 was close but you need the extra step of identifying the form and subform. For the purpose of demonstration let's call the form Attendance and subform Entry then I'll call the second form LookUp. So the code for your double click in the subform field will of course look something like this :
Private Sub Student_DblClick(Cancel As Integer)
DoCmd.OpenForm "LookUp"
End Sub
You really don't need anything else fancy there. For the button on "LookUp" you will put this:
Private Sub Command2_Click()
Forms![Attendance]![Entry].Form![Student] = Forms!Lookup!Student
DoCmd.Close acForm, "LookUp"
End Sub
And that should get you what you want without any overhead or having to leave any ghosts open.
Within Access 2010, I am trying to make a form display a query within a subform QueriesSubForm that when selected from listbox QueryListBox and then click on the button runbtn. It is supposed to display the query within the linked subform, and change when you do this whole steps again from a different choice selected on the listbox and click on the button.
At the moment I can only get it to work, if I want it to display the queries in a new task window, when programmed like so:
QueriesListBox Listbox - SQL View
SELECT MSysObjects.[Name]
FROM MSysObjects
WHERE (((MSysObjects.[Type])=5) AND ((Left([Name],1))<>"~"))
ORDER BY MSysObjects.[Name];
runbtn Button - VBA View
Private Sub runbtn_Click()
DoCmd.OpenQuery QueryListBox, acViewNormal
End Sub
It works and appears to just open one of the queries from the queries list and display it to me, which I do not want.
This might be an easy thing, but I can not see how it is done with either SQL, VBA or Macro, which I am guessing is need for this to work
Ok, here's one way to do it. First make sure your subform is set up with no source object. Then setup your button click like so:
Private Sub runbtn_Click()
Me.QueriesSubForm.SourceObject = "Query." & QueryListBox.Value
End Sub
That should get you the result you're looking for. Alternatively, if you want your form to open with a certain query to displayed on open, you could set up your subform's source object to that query. Using the properties window find the source object drop down and find the query you want to show when the form opens.
I have a main form with a tab control containing multiple subforms. I need to be sure that the data in a subform is saved when the user switches tabs. The problem is that DoCmd.RunCommand acCmdSaveRecord seems only applies to the current form so it doesn't save the data in the subform.
I have tried different events on the subform such as deactivate, OnLostFocus etc but they don't fire until another field somewhere else gets the focus.
The ideal solution would seem to be to put something on the OnChange event of the tab control to be sure that all the data is saved. That is my question, how to do I save the record in a subform?
In Access, the default is to save, so unless you have done something pretty complicated to prevent this, moving the focus from a subform will automatically save the record. You can test this by adding a record, moving from the subform, and then checking the table.
You don't have to do anything at all, as the subform is saved as soon as it loses focus (when the tab control changes).
But as an exercise, I've outlined the code you'd write if you needed to.
You can save any form by setting it's .Dirty property to False. For something like this that's going to run a lot, I think I'd write a sub to walk through the subforms, check if any are dirty, and save the dirty ones. Something like this:
Public Sub SaveSubFormsOnTab()
Dim pge As Control
Dim ctl As Control
For Each pge In Me!ctlTab.Pages
Debug.Print pge.Name
For Each ctl In pge.Controls
If ctl.ControlType = acSubform Then
If ctl.Form.Dirty Then
ctl.Form.Dirty = False
End If
Debug.Print ctl.Name
End If
Next ctl
Next pge
Set ctl = Nothing
Set pge = Nothing
End Sub
Now, that's actually quite inefficient in cases where you have lots of controls on your tab control that aren't subforms. If your tab has nothing but subforms, it will be fairly efficient. In either case, it's much more efficient to use a custom collection populated in the form's OnLoad event, and then you'd walk that collection that includes nothing but your tab control's subforms, and save any that are dirty.
Either of these is preferable to using the OnChange event of the tab, because each time you add a tab page with a subform or change the name of a subform control, you'd have to alter the OnChange event.
I was having a similar issue where I needed various code to run in the subform and values in the main form - that were based on values in the subform - to be recalculated. Here is what finally worked:
This is an example with a main form named 'frmCustomers' containing a subform 'sfmTransaction', which in turn has a subform called 'sfmOrderLine'. The forms have a button 'cmdSave' that is only visible when the user clicks the 'cmdEdit' button (the purpose of which is to lock all the controls until the user clicks the edit button, and then to re-lock them when he clicks save):
On the main form ('frmCustomer') go the subform's exit event, and add 'me.recalc' twice, like this:
Private Sub sfmTransaction_Exit(Cancel As Integer)
If (Not Form_sfmTransaction.NewRecord And Form_sfmTransaction.cmdSave.Visible) Or (Not Form_sfmOrderLine.NewRecord And Form_sfmOrderLine.cmdSave.Visible) Then
'To save subforms
Me.Recalc
Me.Recalc
End If
End Sub
In the subform ('sfmTransaction') go the subform's subform's exit event, and add 'me.recalc' twice, like this:
Private Sub sfmOrderLine_Exit(Cancel As Integer)
If Not Form_sfmOrderLine.NewRecord And Form_sfmOrderLine.cmdSave.Visible Then
'To save subform
Me.Recalc
Me.Recalc
End If
End Sub
Hope this helps.
Setting the dirty property to false may force Access to save the data to the database, but it bypasses the before_update event. This means that if you've used this event for validation or other purposes, you can now have bad data in your database.
