Retrieves a value that indicates the current state of the object.
HRESULT IHTMLFrameBase2::get_readyState(BSTR *p);
- Pointer to a variable of type BSTR that receives one of the values listed in Possible Values.
uninitialized Object is not initialized with data. loading Object is loading its data. loaded Object has finished loading its data. interactive User can interact with the object even though it is not fully loaded. complete Object is completely initialized.
Returns S_OK if successful, or an error value otherwise.
An object's state is initially set to
uninitialized, and then to
loading. When data loading is complete, the state of the link object passes through the
interactivestates to reach the
The states through which an object passes are determined by that object; an object can skip certain states (for example,
interactive) if the state does not apply to that object.
Data source objects and databound elements are normally populated asynchronously, and certain programmatic operations can only be performed reliably on databound objects when they are ready for use. Therefore, the appropriate code should be written to confirm the IHTMLFrameBase2::readyState of objects prior to performing certain operations on them. For example, walking the rows of a table should not be attempted until after the table has reached the
The IHTMLFrameBase2::readyState property enables the status of an object to be tested. The correct place to test the IHTMLFrameBase2::readyState property is in the event handler for onreadystatechange. Similarly, a data source object (DSO) fires the ondatasetcomplete event to notify the document that the dataset is ready for programmatic operation.
