But if I call this in VBA it crashes Excel

VBA code:
Dim helper As String
Private Declare Function calculate Lib "Calculate.dll" (ByVal x as String) As 
String

Sub test ()
  helper = calculate("Test")
  Debug.Print helper
End Sub


All really basic.

Does anybody know why that does not work?

Thanks for all the answers up to now.

Andreas

The 'helper' must be BSTR.

Cheers,
