## ICENodeInputPort.GetValueAtFrame

### Description

Returns the port value as a Variant at a specific frame. The type of the value depends on ICENodePort.DataType. The value stored in this port is only accessible when the port is not connected. If the port is connected, it returns an Empty variant.
Note: This property only returns values for simple types such as float, integer and boolean. Returning other value types is not yet supported. If the port is unable to retrieve the value, it returns an Empty variant.
Tip: Values for non-supported types can be accessed with ICENodePort.Parameters.

### C# Syntax

    Object ICENodeInputPort.GetValueAtFrame( Object inFrame );

### Scripting Syntax

    oVariant = ICENodeInputPort.GetValueAtFrame( Frame );

### Return Value

Variant

### Parameters

Parameter | Type | Description
--- | --- | ---
Frame | Variant | Frame at which to set the value.

### Examples

#### Python Example

    #
    # This example demonstrates how to get a non-connected Node port value at different time
    #
    import win32com.client
    from win32com.client import constants
    xsi = Application
    xsi.NewScene("", 0)
    xsi.CreatePrim("Grid", "MeshSurface", "", "")
    xsi.ApplyOp("ICETree", "grid", "siNode", "siPersistentOperation", "", 0)
    xsi.AddICENode("InitializeNode", "grid.polymsh.ICETree")
    xsi.SetValue("grid.polymsh.ICETree.InitDataNode.PredefinedAttributeName", "EdgeLength", "")
    xsi.AddAttributeToSetDataICENode("grid.polymsh.ICETree.InitDataNode", "EdgeLength", constants.siComponentDataTypeFloat, constants.siComponentDataContextComponent1D, constants.siComponentDataStructureSingle )
    xsi.SelectObj("grid.polymsh.ICETree.InitDataNode", "", "")
    initDataNode = xsi.Selection(0)
    nodeport = initDataNode.InputPorts("EdgeLength")
    xsi.SaveKey( "grid.polymsh.ICETree.InitDataNode.EdgeLength", 1.000, 5.000 );
    xsi.SaveKey( "grid.polymsh.ICETree.InitDataNode.EdgeLength", 5.000, 25.000 );
    xsi.LogMessage( "EdgeLength value at frame 1: " + str(nodeport.GetValueAtFrame(1.0)) )
    nodeport.PutValueAtFrame( 5.0, 85.0 )
    xsi.LogMessage( "EdgeLength value at frame 5: " + str(nodeport.GetValueAtFrame(5.0)) )
    # Expected results:
    # INFO : EdgeLength value at frame 1: 5.0
    # INFO : EdgeLength value at frame 5: 85.0
