Hi there, i want to change a string to a form name, for example:

dim FormName as string = Form2

dim newform as form = FormName

newform.show()


From what I've read I need to use system.reflection for this but I'm stabbing wildly in the dark.

Thanks!

Try the following:
        Dim FormName As String = "My Form"
        Dim newform As Form = New Form
        newform.Name = FormName
        newform.Show()

You should be able to create a new form and give the form a name.

Dim FormName as String = Form2
Dim newform as new Form()
newForm.Name = FormName

newForm.Show

Sorry, that just creates a brand new form, I already have the form created. Im trying to open this form and add to a panel from a treeview based on its tag name.

Your code must be changed to:

        Dim FormName As String = "Form2"
        Dim newform As Form = New Form
        newform = GetFormByName(FormName)
        newform.Show()

and the method GetFormByName is attached ;)
    Private Function GetFormByName(ByVal formName As String) As Object
 
        Dim myasm As System.Reflection.Assembly = System.Reflection.Assembly.GetExecutingAssembly()
 
        Try
            Return myasm.CreateInstance(myasm.GetName.Name.Replace(" ", "_") & "." & formName)
 
        Catch ex As Exception
            Return Nothing
        End Try
 
    End Function

You are correct - reflection is required. The below example shows how.

Wayne
        Dim FormName As String = "Form2"
        Dim newform As Form = CType(Reflection.[Assembly].GetEntryAssembly.CreateInstance( _
                                    My.Application.Info.AssemblyName & "." & FormName), Form) 
        newform.Show()
