Are designers dymanically creatable?

I'm trying to write a general report handler as class in an ActiveX exe. The code beneath is pretty self explanatory. Pass in a recordset and reportname, create the report, give it the recordset and print.

Code:

---

Private mObjReport as Object

Public Sub PrintReport(ReportName As String, rs As Recordset)
'Pass in the report name and recordset to be printed

Set mObjReport = CreateObject(ReportName)

mObjReport.Database.SetDataSource rs

mObjReport.PrintOut

End Sub

---

The thing specified by ReportName must be a Crystal 8 Designer already defined in the project. If I try to do this I get 'ActiveX can't create component'.

If I do

Code:

---

Private mRptReport as New CrystalReport1

---

it works fine. If I pass in the string 'CrystalReport1' and use that in CreateObject, I get the can't create component error. Am I trying to do something impossible or am I just doing something wrong?
