SerializeInfo type (UDT)

The per-instance serializer for a custom control, returned by CustomControlContext.GetSerializer. The main entry point is RuntimeUISrzDeserialize — called from a control’s Initialize to load the designer-set property values that were saved into the form’s serialized data. The remaining members expose framework state — design-mode flag, runtime / report mode, owner window handle — that a control may need while initializing.

Private Sub OnInitialize(ByVal Ctx As CustomControls.CustomControlContext) _
        Implements CustomControls.ICustomControl.Initialize

    With Ctx.GetSerializer
        If Not .RuntimeUISrzDeserialize(Me, False) Then
            InitializeDefaultValues
        End If

        Me.IsDesignMode = .RuntimeUISrzIsDesignMode()
    End With

    Set Me.ControlContext = Ctx
End Sub

Methods

RuntimeUISrzDeserialize

Loads the serialized property values for this control instance into Object. Returns True if serialized data was present and was applied, or False if no data was found — in which case the control should apply its own defaults.

Syntax: SerializeInfo.RuntimeUISrzDeserialize ( Object, UseOuterOwner ) As Boolean

Object

required The custom control instance whose properties should be populated. From inside an Initialize implementation this is Me.

UseOuterOwner

required A Boolean flag for advanced use; pass False in normal cases.

RuntimeUISrzGetFormHWND

Returns the HWND of the parent form’s underlying Win32 window.

Syntax: SerializeInfo.RuntimeUISrzGetFormHWND ( ) As LongPtr

RuntimeUISrzGetOrientationHint

Returns a hint indicating the orientation of the parent form. Long.

Syntax: SerializeInfo.RuntimeUISrzGetOrientationHint ( ) As Long

RuntimeUISrzGetRootCLSID

Returns the CLSID of the form class that owns this control, as a String.

Syntax: SerializeInfo.RuntimeUISrzGetRootCLSID ( ) As String

RuntimeUISrzGetRootClassDispatch

Returns the form-class instance that owns this control, typed as an Object.

Syntax: SerializeInfo.RuntimeUISrzGetRootClassDispatch ( ) As Object

RuntimeUISrzIsDesignMode

Returns True if the control is being created at design time (inside the form designer) rather than at run time. Controls that want to render a placeholder at design time only — like WaynesTimer, which draws its 🕑 glyph only when IsDesignMode is True — read this flag during Initialize.

Syntax: SerializeInfo.RuntimeUISrzIsDesignMode ( ) As Boolean

RuntimeUISrzIsReportMode

Returns True if the control is being created as part of a report-rendering pass.

Syntax: SerializeInfo.RuntimeUISrzIsReportMode ( ) As Boolean

RuntimeUISrzIsRuntimeAdded

Returns True if the control was added at run time (via CustomControlsCollection.Add) rather than placed in the form designer.

Syntax: SerializeInfo.RuntimeUISrzIsRuntimeAdded ( ) As Boolean
