) : Object

Parameters

key

Return Value

Type: Object
If successful, returns an object representing the requested data; otherwise, returns an error code.

Remarks

This method obtains the IVsUserData interface from the IVsTextLines object (which was passed to the Source class constructor), and then calls the GetData method with the given GUID.

The following GUIDs are supported:

GUID	Value Type	Description
GUID_VsLang_Support_CF_HTML	Boolean	True if the language service recognizes the clipboard format CF_HTML and allows pasting of HTML fragments.

Examples

Here is an example of how to call this method (see "Language GUIDs" section of the IDE GUIDs topics to get the value for the GUID_VsLang_Support_CF_HTML constant).

namespace MyLanguagePackage
{
    class MySource : Source
    {
        bool IsHTMLSupported()
        {
            bool bSupported = false;
            object value = GetUserData(GUID_VSLang_Support_CF_HTML);
            if (value != null)
            {
                bSupported = Convert.ToBoolean(value);
            }
            return bSupported;
        }
    }
}
