IsSearchProviderInstalled method
Determines if a search provider has been installed for the current user and whether it is set as default.
Syntax
DWORD retVal = object.IsSearchProviderInstalled(URL);
Parameters
URL [in]
Type: BSTRString that specifies a prefix to the URL for the search provider.
Remarks
IsSearchProviderInstalled was introduced in Windows Internet Explorer 7.
This method indicates whether a specific search provider is installed and is the default search provider for the current user. To determine if a search provider is installed, IsSearchProviderInstalled compares the value of the URL parameter to the list of installed search providers. If any search provider starts with the parameter value, the method indicates a match.
Sites are only allowed to search for providers on the same domain. For example, images.example.com may search for http://search.example.com; however, it cannot search for providers on microsoft.com or other domain names. Searching for providers on different domains generates access denied errors.
