CodeEvent.InfoLocation Property

Gets the capabilities of the code model.

Namespace:  EnvDTE80
Assembly:  EnvDTE80 (in EnvDTE80.dll)

Syntax

'Declaration
ReadOnly Property InfoLocation As vsCMInfoLocation

vsCMInfoLocation InfoLocation { get; }

property vsCMInfoLocation InfoLocation {
    vsCMInfoLocation get ();
}

abstract InfoLocation : vsCMInfoLocation

function get InfoLocation () : vsCMInfoLocation

Property Value

Type: EnvDTE.vsCMInfoLocation
One of the vsCMInfoLocation values.

Remarks

If InfoLocation returns vsCMInfoLocationProject, then you can set properties, obtain a StartPoint, obtain an EndPoint, and so forth. When you go from one code model object (A) to another (B) — such as from a function to its type or from a class to its base class — B may be of type vsCMInfoLocationExternal if its definition is in another project. The disposition depends on the code model implementation, whether object B's project is implemented in the same language as object A's, and so forth.

If InfoLocation returns vsCMInfoLocationExternal, then information is available only from metadata, from inspecting a DLL, or from frozen sources. You may be able to obtain a StartPoint and EditPoint, but you cannot edit the document; that is, you cannot set properties or modify the text behind the code element.

If InfoLocation returns vsCMInfoLocationNone, then all that is available is a code model object that has a name. Also, based on the context of the source code, in some cases you can tell whether the name should be a class or an interface. In this situation, however, because the code model could not resolve the name to any useful information, the object is otherwise useless.

Note

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).

Examples

The following example demonstrates how to use the InfoLocation property.

To test this property:

1. Open the target project and select the code event element by placing the cursor on the event object.

2. Run the add-in.

public static void InfoLocation(EnvDTE80.DTE2 dte)
{
    TextSelection objTextSel;
    EnvDTE80.CodeEvent codeEvent;
    objTextSel = (TextSelection)dte.ActiveDocument.Selection;
    codeEvent = (EnvDTE80.CodeEvent)objTextSel.ActivePoint.get_CodeElement(vsCMElement.vsCMElementEvent);

    MessageBox.Show("\nInfoLocation property: " +
                    codeEvent.InfoLocation, "Testing CodeEvent");
}
