INetDiagHelper::Validate method (ndhelper.h)

  • Article

The Validate method is called by NDF after a repair is successfully completed in order to validate that a previously diagnosed problem has been fixed.

Syntax

HRESULT Validate(
  [in]  PROBLEM_TYPE  problem,
  [out] long          *pDeferredTime,
  [out] REPAIR_STATUS *pStatus
);

Parameters

[in] problem

The PROBLEM_TYPE that the helper class has previously diagnosed.

[out] pDeferredTime

A pointer to the time to be deferred, in seconds, if the diagnosis cannot be started immediately. This is used only when the pStatus member is set to DS_DEFERRED.

[out] pStatus

A pointer to the DIAGNOSIS_STATUS that is returned from the diagnosis.

Return value

Return code Description
S_OK
 The operation succeeded.
E_OUTOFMEMORY
 There is not enough memory available to complete this operation.
E_INVALIDARG
 One or more parameters has not been provided correctly.
E_NOTIMPL
 This optional method is not implemented.
E_ACCESSDENIED
 The caller does not have sufficient privileges to perform the diagnosis or repair operation.
E_ABORT
 The diagnosis or repair operation has been canceled.
 

Helper Class Extensions may return HRESULTS that are specific to the failures encountered in the function.

Remarks

This method is not required when building a Helper Class Extension.

This method only returns an error code if it encounters failures that impede validation. If necessary, the pStatus parameter is the expected way to communicate that the component is still in low health. DS_REJECTED is used to indicate that the issue has been resolved.
