getrunningobjecttable (ole32)

C# Signature:

    /// <summary>
    /// Returns a pointer to the IRunningObjectTable
    /// interface on the local running object table (ROT).
    /// </summary>
    /// <param name="reserved">This parameter is reserved and must be 0.</param>
    /// <param name="prot">The address of an IRunningObjectTable* pointer variable
    /// that receives the interface pointer to the local ROT. When the function is
    /// successful, the caller is responsible for calling Release on the interface
    /// pointer. If an error occurs, *pprot is undefined.</param>
    /// <returns>This function can return the standard return values E_UNEXPECTED and S_OK.</returns>
    static extern int GetRunningObjectTable(uint reserved,
       out System.Runtime.InteropServices.ComTypes.IRunningObjectTable pprot);

User-Defined Types:



In .Net 2.0 use System.Runtime.InteropServices.ComTypes.IRunningObjectTabl as the second parameter. Frameworks 1.0 and 1.1 use a now deprecated type.

Please note that the Register method of the IRunningObjectTable interface actually returns the "cookie" value needed to Revoke the object from the ROT at a later point. The MSDN documentation is confusing; perhaps wrong.

Tips & Tricks:

Please add some!

Sample Code:

     System.Runtime.InteropServices.ComTypes.IRunningObjectTable objTbl;
     Int32 hr = GetRunningObjectTable(0, out objTbl);
     if (hr == 0) // success
     else // failure
