>Hi!
>We are trying to check if an active x control is registered on a form so that we can run regsvr32 if it is not and avoid any error messages for the user. We are able to see trap the error - but not until after the form has started to load and the open dialogue box has appeared. Does anyone know a good way to tell if a control is not registered without alerting the user? (This situation should be rare so we don't want to use any api functions to check for this everytime - it would be wastefule).

Got to use the API and still it may not be 100% reliable. You can for the ProgID under HKEY_CLASSES_ROOT in the registry. If it's there, the control is probably registered. However, there's being registered and being correctly registered. For example, the Common Dialog control on the target machine must be registered with the appropriate CLSID key and there's one for design time and one for run-time and they're not interchangable.
