IUpdateInstaller::IsBusy property

Gets a Boolean value that indicates whether an installation or uninstallation is in progress on a computer at a specific time.

This property is read-only.

Syntax

HRESULT get_IsBusy(
  [out] VARIANT_BOOL *retval
);

Property value

VARIANT_TRUE if an installation or uninstallation is in progress on the computer.

VARIANT_FALSE if an installation or uninstallation is not in progress on the computer.

Note  A new installation or uninstallation will only be processed when no other installation or uninstallation is in progress.

Error codes

Returns S_OK if successful. Otherwise, returns a COM or Windows error code.

Remarks

A new installation or uninstallation is processed only when no other installation or uninstallation is in progress. While an installation or uninstallation is in progress, a new installation or uninstallation immediately fails with the WU_E_OPERATIONINPROGRESS error. The IsBusy property does not secure an opportunity for the caller to begin a new installation or uninstallation. If the IsBusy property or a recent installation or uninstallation failure indicates that another installation or uninstallation is already in progress, the caller should attempt the installation or uninstallation later.
