Open multiple forms issue in Access - ms-access

Question

I got query to make some modification that enable user to open multiple instances of the form when they do search data. I got manage to create a new module following Allen Browne guide and now I can open multiple instances of the spreadsheet which is good step forward but I cannot find solution how I can open that specific form.
In module I have got following code:
Public clnClient As New Collection 'Instances of frmClient.
Function OpenAClient()
'Purpose: Open an independent instance of form frmClient.
Dim frm As Form
'Open a new instance, show it, and set a caption.
Set frm = New Form_SurgeriesForm
frm.Visible = True
frm.Caption = frm.Hwnd & ", opened " & Now()
'Append it to our collection.
clnClient.Add Item:=frm, Key:=CStr(frm.Hwnd)
Set frm = Nothing
End Function
And under my button I replaced bit:
DoCmd.OpenForm "SurgeriesForm", acNormal
Forms!SurgeriesForm.Requery
.. and usef following code:
ModuleInstances.OpenAClient
I recon I need to add / change somehow the code below to be able to open multiple instances but do not have idea how to do it.
DoCmd.OpenForm "SurgeriesForm", acNormal
Forms!SurgeriesForm.Requery
I appreciate for any help with this as i got stuck and do not know how I can achieve this.

Answer 1

I think this is what you want?...
With the button on your SurgeriesForm add this code to the On Click event to open a new instance of the form:
Private Sub Command8_Click()
OpenAClient
End Sub
This will create a new instance of the form each time you click the button.
Next, add a blank combo-box to the form and change it's Row Source Type to Value List.
Add this code to the form:
Private Sub Combo9_GotFocus()
Dim frm As Variant
Combo9.RowSource = ""
For Each frm In clnClient
Combo9.AddItem frm.Caption
Next frm
End Sub
Now, when you click the drop-down it will list each form that you have created an instance of.
Finally, add this code to the form:
Private Sub Combo9_AfterUpdate()
clnClient(Combo9.Value).SetFocus
End Sub
Now, selecting a form name from the combo-box will move the focus to that form.
NB: You'll need to update the name of the controls to match yours.
NB2: Remember to open the first form using OpenAClient or it won't get listed in the combobox (as it's not in the collection).
