Convert IUIAutomationElement to IUIAutomationElement6, to invoke get_CurrentFullDescription method
To convert an IUIAutomationElement
interface to IUIAutomationElement6
in order to invoke the get_CurrentFullDescription
method, you need to follow these steps:
Retrieve the
IUIAutomationElement
interface for the element you want to work with. This can be done using various methods from the UI Automation API, such asRootElement
,FindFirst
, orBuildUpdatedCache
.Query the
IUIAutomationElement
interface for theIUIAutomationElement6
interface. You can use theQueryInterface
method of theIUIAutomationElement
interface to obtain theIUIAutomationElement6
interface. Here's an example:
cppIUIAutomationElement* automationElement; // The existing IUIAutomationElement interface
// Query for IUIAutomationElement6
IUIAutomationElement6* automationElement6 = nullptr;
HRESULT hr = automationElement->QueryInterface(IID_IUIAutomationElement6, reinterpret_cast<void**>(&automationElement6));
if (SUCCEEDED(hr))
{
// Use the automationElement6 interface to invoke the get_CurrentFullDescription method
BSTR fullDescription;
hr = automationElement6->get_CurrentFullDescription(&fullDescription);
if (SUCCEEDED(hr))
{
// Process the fullDescription as needed
// ...
// Release the BSTR
SysFreeString(fullDescription);
}
// Release the IUIAutomationElement6 interface
automationElement6->Release();
}
In the example above, automationElement
represents the existing IUIAutomationElement
interface that you have obtained. The QueryInterface
method is used to obtain the IUIAutomationElement6
interface from the automationElement
. Then, you can invoke the get_CurrentFullDescription
method on automationElement6
to retrieve the full description of the element.
Remember to check the return values of the API calls for success or failure. Proper error handling and memory management should be implemented as required.
Please note that the availability of the IUIAutomationElement6
interface and the get_CurrentFullDescription
method depends on the version of the UI Automation API you are using. Make sure you are targeting a compatible version of the API that supports these features.
