    Exclamation No Such Interface Supported

    Hi, I am trying to replace styles in a document (doc or docx) with styles from a template document (dotx). I've imported the dotx into the document with

    Code:
    Globals.ThisAddIn.Application.ActiveDocument.CopyStylesFromTemplate(Template:=DirectoryForRestyler & cbxNewStyleSheets.SelectedItem.ToString & ".dotm")
    so that all the styles needed exist in the document. I then have a CustomTaskPane where the user selects the old style from the document by range, and replaces it with a new style.

    When they click Replace Styles, I'm getting this

    Code:
     No such interface supported
    
    No such interface supported
    
      at Microsoft.Office.Interop.Word.Range.set_Style(Object& prop)
       at <application>.Button1_Click(Object sender, EventArgs e) in <redacted>.vb:line 77
       at System.Windows.Forms.Control.OnClick(EventArgs e)
       at System.Windows.Forms.Button.OnClick(EventArgs e)
       at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
       at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
       at System.Windows.Forms.Control.WndProc(Message& m)
       at System.Windows.Forms.ButtonBase.WndProc(Message& m)
       at System.Windows.Forms.Button.WndProc(Message& m)
       at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
    It's got me at a complete roadblock and I don't know how to progress. Looking at the microsoft docs, it states I should be able to set the style, so I'm not sure where I am going wrong.

    If you need any more details, I can provide them. Help would be appreciated. Thanks.

    I've imported the dotx into the document with
    can you then use the imported styles if you change the style manually?
    i do my best to test code works before i post it, but sometimes am unable to do so for some reason, and usually say so if this is the case.
    Note code snippets posted are just that and do not include error handling that is required in real world applications, but avoid On Error Resume Next

    dim all variables as required as often i have done so elsewhere in my code but only posted the relevant part

    come back and mark your original post as resolved if your problem is fixed

    Yes, I am able to use the styles manually by selecting them from Home > Styles.

    does styletosetto contain a valid style object?

    This is what I have, I noticed that the type is different but not sure how to get around this.

    + par.Range.Style {System.__ComObject} Object {System.__ComObject}
    + styleToSetTo {System.__ComObject} Microsoft.Office.Interop.Word.Style {System.__ComObject}
