Sub Form Question

[Giri Palakodeti]

I am opening a form dynamically in VBA code in design view and making changes

DoCmd.OpenForm rs1("Form"), acDesign

But for sub-forms the above statement fails. How can i check if
rs1("Form") is a sub-form and how do I open in design view to make changes
programatically to some of the properties and controls

I am having this error
"This form or report is already being designed as a subform or subreport. To
open this form in Design view, select the subform or subreport and click
Subform in New Window on the View menu."

Anything that I missed??
