IDataset / 2147467259 HResult COM Error

Dear everybody:

I have problems with this line of code:

            pDS = pGPUtils.OpenFeatureClassFromString(ruta & outname)

The error message is in spanish:
"-2147467259 Devuelto error HRESULT E-Fail de una llamada a un componente COM"

You may see in the complete code that the code makes a selection of a combination of Featureclass-joined table. The sql-string gets one value of the for-next-structure and finally it checks if some records are selected. Only if their are some records selected it exports the selected records to a new shape.

This boocle is correct only for 1 selection. Once a shapfile is exported and the boocle repeats I get this error mentioned above in the following line of code:
pDS = pGPUtils.OpenFeatureClassFromString(ruta & outname)

What is wrong with the IDataset? Shall I initialize every time the boocle repeats? Their seems to be a COM problem but I don´t know what kind of?

Thanks very much for your help!!

Anika
