範例

以下範例中，第一行用於 CallByName 設定 Text 文字框的屬性，第二行取得該屬性的 Text 值，第三行則呼叫 Move 移動文字框的方法。

' Imports statements must be at the top of a module.
Imports Microsoft.VisualBasic.CallType

Sub TestCallByName1()
    'Set a property.
    CallByName(TextBox1, "Text", CallType.Set, "New Text")

    'Retrieve the value of a property.
    MsgBox(CallByName(TextBox1, "Text", CallType.Get))

    'Call a method.
    CallByName(TextBox1, "Hide", CallType.Method)
End Sub

下一個範例使用 CallByName 函式來呼叫 Add 集合物件的 and Item 方法。

Public Sub TestCallByName2()
    Dim col As New Collection()

    'Store the string "Item One" in a collection by 
    'calling the Add method.
    CallByName(col, "Add", CallType.Method, "Item One")

    'Retrieve the first entry from the collection using the 
    'Item property and display it using MsgBox().
    MsgBox(CallByName(col, "Item", CallType.Get, 1))
End Sub
