AsyncType

Returns the kind of data being read, as an AsyncTypeConstants value. Read-only.

Syntax: object.AsyncType

object

required An object expression that evaluates to an AsyncProperty object.

The value mirrors the AsyncType argument passed to UserControl.AsyncRead when the read was started. It also determines the subtype of Value once the read completes:

• vbAsyncTypePicture (0) --- the data is being delivered as an stdole.IPictureDisp.
• vbAsyncTypeFile (1) --- the data is being saved to a temporary file; Value holds its path as a String.
• vbAsyncTypeByteArray (2) --- the data is being delivered as a Byte array.

Example

This example checks AsyncType in the completion event and assigns the result to the appropriate property.

Private Sub UserControl_AsyncReadComplete(AsyncProp As AsyncProperty)
    If AsyncProp.PropertyName = "Picture" Then
        If AsyncProp.AsyncType = vbAsyncTypePicture Then
            Set UserControl.Picture = AsyncProp.Value
        End If
    End If
End Sub
