PictureBoxArray.DragOver 事件


發生於將物件拖曳至控制項邊框上方時。Occurs when an object is dragged over the control's bounds.

 event System::Windows::Forms::DragEventHandler ^ DragOver;
public event System.Windows.Forms.DragEventHandler DragOver;
member this.DragOver : System.Windows.Forms.DragEventHandler 
Public Custom Event DragOver As DragEventHandler 
Public Event DragOver As DragEventHandler 


在拖放作業期間,當滑鼠游標在控制項的範圍內移動時,就會引發 DragOver 事件。The DragOver event is raised when the mouse cursor moves within the bounds of the control during a drag-and-drop operation.

Microsoft.VisualBasic.Compatibility.VB6 命名空間中的函式和物件都是供這些工具使用,以便從 Visual Basic 6.0 升級至 Visual Basic。Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic. 在大多數情況下,這些函式和物件會複製在 .NET Framework.NET Framework 的其他命名空間中可以找到的功能。In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework.NET Framework. 只有當 Visual Basic 6.0 程式碼模型與 .NET Framework.NET Framework 實作有顯著差異時,才需要這些項目。They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework.NET Framework implementation.
