當您在 Microsoft Visual Studio 2005 或 Microsoft Visual Studio .NET 中使用 Microsoft Visual Basic 6.0 ActiveX 控件時，可能會遇到以下問題： 在您嘗試將隨 Visual Basic 6.0 一起提供的 ActiveX 控件添加到 Visual Studio 2005 或 Visual Studio .NET 窗體中時，會收到以下錯誤消息：
You do not have a
license to use this ActiveX control.
您必須具有設計時許可證，纔可以使用 Visual Basic 6.0 ActiveX
控件。造成這些錯誤的原因是系統註冊表不包含設計時許可證信息。在您升級包含 Visual Basic 6.0 ActiveX
控件的項目時，或者嘗試在 Visual Studio 2005 或 Visual Studio .NET 窗體上使用 Visual Basic
6.0 ActiveX 控件時，這些控件必須安裝在目標系統上並且具有在目標系統上使用的許可證。
Visual Studio 2005 和 Visual Studio .NET 不會安裝 Visual Basic 6.0 ActiveX 控件的許可證信息，除非 Visual Basic 6.0 控件安裝在運行 Visual Studio 2005 或 Visual Studio .NET 的計算機上。如果計算機上從未安裝過 Visual Basic 6.0，則可能會出現該問題。
您不會在同時安裝了 Visual Basic 6.0 和 Visual Studio 2005 或 Visual Studio .NET 的計算機上收到這些錯誤，因爲 Visual Basic 6.0 會安裝這些組件並註冊許可證。
