Returns the class object associated with a CLSID.

Namespace: Microsoft.VisualStudio.Shell.Interop
Assembly: Microsoft.VisualStudio.Shell.Interop (in Microsoft.VisualStudio.Shell.Interop.dll)

Syntax

'Declaration
Function GetClassObjectOfClsid ( _
    ByRef clsid As Guid, _
    dwFlags As UInteger, _
    lpReserved As IntPtr, _
    ByRef riid As Guid, _
    <OutAttribute> ByRef ppvClassObject As IntPtr _
) As Integer

'Usage
Dim instance As ILocalRegistry 
Dim clsid As Guid 
Dim dwFlags As UInteger 
Dim lpReserved As IntPtr 
Dim riid As Guid 
Dim ppvClassObject As IntPtr 
Dim returnValue As Integer 

returnValue = instance.GetClassObjectOfClsid(clsid, _
    dwFlags, lpReserved, riid, ppvClassObject)

int GetClassObjectOfClsid(
    ref Guid clsid,
    uint dwFlags,
    IntPtr lpReserved,
    ref Guid riid,
    out IntPtr ppvClassObject
)

int GetClassObjectOfClsid(
    [InAttribute] Guid% clsid, 
    [InAttribute] unsigned int dwFlags, 
    [InAttribute] IntPtr lpReserved, 
    [InAttribute] Guid% riid, 
    [OutAttribute] IntPtr% ppvClassObject
)

function GetClassObjectOfClsid(
    clsid : Guid, 
    dwFlags : uint, 
    lpReserved : IntPtr, 
    riid : Guid, 
    ppvClassObject : IntPtr
) : int

Parameters

clsid
Type: System.Guid%

[in] Class identifier (CLSID) of the requested object. This is the CLSID associated with the data and code that is used to create the object.

dwFlags
Type: System.UInt32

[in] Flags controlling the instance creation from the CLSCTX enumeration. Specifies a value of CLSCTX_INPROC_SERVER.

lpReserved
Type: System.IntPtr

[in] Reserved.

riid
Type: System.Guid%

[in] Interface to be used to communicate with the object. For example, IID_IClassFactory.

ppvClassObject
Type: System.IntPtr%

[in] Address of pointer variable that receives the interface pointer requested in riid. Upon successful return, ppvObj contains the requested interface pointer. Upon failure, ppvObj contains nulla null reference (Nothing in Visual Basic).

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From objext.idl:

HRESULT ILocalRegistry::GetClassObjectOfClsid(
   [in] REFCLSID clsid,
   [in] DWORD dwFlags,
   [in] LPVOID lpReserved,
   [in] REFIID riid,
   [in] void** ppvClassObject
);

Specify a value of CLSCTX_INPROC_SERVER for the dwFlags parameter to instantiate the object locally. If you do not specify this value, then the object will be instantiated globally using COM's CoCreateInstance function.
