Careful with checking variable states like that, if Form1 is not loaded, referencing a public variable on Form1 will cause it to load if I am not mistaken.

 

You could set an object as a form;

 

Private obFrm As Form

 

Somehwere in code when form is needed:

 

Set obFrm = New Form1
obFrm.Show

 

then later in code, check it like this:

 

If Not obFrm Is Nothing Then
    'form is loaded
End If

 

 

The CommandBars_Execute will be fired when a button is pressed 

 

When you want to check which item is active you can use the CommandBars_Update event

 

Private Sub CommandBars_Update(ByVal Control As XtremeCommandBars.ICommandBarControl)
    Select Case Control.ID
        Case ID_TOOLBAR_BUTTON_1
            Control.Checked = Form1.IsLoaded 'Isloaded = public variable in form1 which is set to true when form is loaded

        Case ID_TOOLBAR_BUTTON_2
            Control.Checked = Form2.IsLoaded 'Isloaded = public variable in form2 which is set to true when form is loaded 

    End Select
End Sub

 

 

 

When i click on a button i'm using this procedure to check what is pressed

 

Private Sub CommandBars_Execute(ByVal Control As XtremeCommandBars.ICommandBarControl)
Select Case Control.id
    Case 101
    
        form1.Show 1
    Case 102
        form2.Show 1
end select

 

 

Where do i write the .checked=true?

 

You mean like a checked button?

 

 

Just like an ordinary button with  .Checked = true

 

 

Please, explain what you mean by: "an item"

How to implement so when i'm selecting an item from commandbar to stay selected until i'm selecting something else?

 

Thank you
