Jim,

Making the second form do this seriously breaks encapsulation. Why not just structure you code like this:

DO FORM AddVendor (assumed it's a modal form)
this.cboListOfVendors.Requery()

If the AddVendor form is not modal you could pass a reference to the form to the other form when you launch it. Then the other form can send a message back to the first form:

DO FORM AddVendor with thisform

AddVendor.Init:
lparameter roCallerForm

this.oCaller = roCallerForm

then when you want to inform the other form of the changes

thisform.oCaller.UpdateVendors()


>How do you reference a combobox on a form that is not the active form? I open a new form to add a vendor and want to requery the combobox so it has the updated vendor, but it is on another form that is present as soon as I close the vendor add form. I have always used thisform.etc.etc, but what do you use if it is not on thisform?
