Hi Torgny.

>But I have another problem, also appearing only with SDT6.0 not with 5.0. The following code worked fine in SDT5.0 but now I get an "File access is denied (Error 1705)" inside the OpenData-method.

We changed error handling in SDT 5.1 to do a more complete job of reporting errors, and this was one of the effects. However, you can disable the display of the error dialog by setting goMeta.lSuppressErrors = .T.
