Syntax

'宣言
Function OnWindowActivate ( _
    dwWindowType As UInteger, _
    fActivate As Integer _
) As Integer
'使用
Dim instance As IOleInPlaceComponent
Dim dwWindowType As UInteger
Dim fActivate As Integer
Dim returnValue As Integer

returnValue = instance.OnWindowActivate(dwWindowType, _
    fActivate)

    uint dwWindowType,
    int fActivate
)
int OnWindowActivate(
    [InAttribute] unsigned int dwWindowType, 
    [InAttribute] int fActivate
)
abstract OnWindowActivate : 
        dwWindowType:uint32 * 
        fActivate:int -> int 
function OnWindowActivate(
    dwWindowType : uint, 
    fActivate : int
) : int

Parameters

  • dwWindowType
    Type: System.UInt32
    [in] Specifies the type of window that is being activated. For a list of valid dwWindowType values, see OLEACTIVATE.
  • fActivate
    Type: System.Int32
    [in] Flag that is set to true if the window is activating and false if it is deactivating.

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 oleipc.idl:

HRESULT IOleInPlaceComponent::OnWindowActivate(
   [in] DWORD dwWindowType,
   [in] BOOL fActivate
);

The OnWindowActivate method communicates the same information to an in-place VSPackage object that the innermost active object gets through OnFrameWindowActivate and OnDocWindowActivate. If an in-place object assuming the role of main component or subcomponent is the UI active object, only OnWindowActivate will be called. If the UI active object is assuming the role of a component control, only OnDocWindowActivate will be called.
