[RESOLVED] SetFocus on form created in RunTime

Hi :)

My app creates several forms in runtime and I want to set focus on it.
How can I make this?

Thank you

Only one form can have focus at a time and loading the form after it is created should establish focus.

Yes, I understand that, but my real problem is a little diferent.Let me explain:
I've got a TreeView with multiple nodes, each node creates a form in runtime.
Meanwhile, the user opens another app windows, and then, clicks again in the TreeView.
I'm validating if the forms created in runtime are open or close (using a array , type boolean).
So, when the user clicks for the 2nd, 3rd, ... time in the treeview, the window should get focus,if it's open already. If not, then the app will create the form in runtime and, off-course, the new window will get focus.

What is your code for your validation array?

The var (List) is an array.
This var is based uppon the node.Key of TreeView.

Code:

---

List= CInt(Replace(Node.Key, "n", ""))

---

When I create the form:

Code:

---

FormInUse(List) = True

---

When I close the form:

Code:

---

FormInUse(List) = False

---

Could I use API's?

Doesn't .Showing the form set focus to it even if it's already been shown?

No, dude, because when I do "formList.show" it only show my basic form, not the runtime form created.

I'm not understanding your problem then, because testing it out both .Show and .SetFocus seem to do what you're looking for.

Create a new project with two forms. (Form1 & Form2) Add two command buttons to Form1. (Command1 & Command2) Then copy this code to Form1's module. Then run it.

Clicking Command1 will create new forms. Clicking Form2 will cause the first created form to get the focus using the .Show method. .SetFocus works as well.

Code:

---

Option Explicit

Private Sub Command1_Click()
    Static lngNumber As Long
    Dim frm As Form
   
    lngNumber = lngNumber + 1
    Set frm = New Form2
    frm.Caption = lngNumber
    frm.Show
    Set frm = Nothing
End Sub

Private Sub Command2_Click()
    Dim frm As Form
   
    For Each frm In Forms
        If frm.Caption = "1" Then frm.Show
    Next
    Set frm = Nothing
End Sub

---

Ok, that should work, but not in my specific case. Some forms created in runtime must have the same caption.
Forms must have an unique identifier internally, right?
If so, how can I determine it? Is there any API function to do it?

Thank you

Using API and determining the form's internal ID number is way overkill. Just make up your own unique identifier for the forms, (like, say, the treeview node's .Key property) and stuff that into the forms' .Tag property.

Code:

---

Option Explicit

Private Sub Command1_Click()
    Dim frm As Form

    If Not Treeview1.SelectedItem Is Nothing Then
        Set frm = New Form2
        frm.Tag = Treeview1.SelectedItem.Key
        frm.Show
        Set frm = Nothing
    End If
End Sub

Private Sub Command2_Click()
    Dim frm As Form
   
    For Each frm In Forms
        If frm.Tag = [some value] Then frm.Show
    Next
    Set frm = Nothing
End Sub

---

Thanks for the suggestion. I've use the tag property to track my forms.
Here it goes the code:

Code:

---

Private Sub Navigator_NodeClick(ByVal Node As MSComctlLib.Node)
Dim NodeClick As Integer
Dim formul As Form
On Error Resume Next 

If FormInUse(NodeClick) Then
    For Each formul In Forms
        If formul.Tag = NodeClick Then formul.SetFocus
    Next
    Exit Sub
Else
    Set NewForm = New Lista 
    NewForm.Show           
    NewForm.Tag = NodeClick
    NewForm.load_Grid (NodeClick)
    Set NewForm = Nothing 
End If



End Sub

---

Thank you all
:wave:

That can't possibly work, or it is incomplete. NodeClick is always zero; you never set it to anything.
