NETHostCtrl.hWnd Property (ExNETHost)

The hWnd property returns the handle of the window that displays the NETHost control. The hWnd property does not return the handle of the hosting control. The Microsoft Windows operating environment identifies each form and control in an application by assigning it a handle, or hWnd. The hWnd property is used with Windows API calls. Many Windows operating environment functions require the hWnd of the active window as an argument. The Host property returns the object being created and hosted by the NETHost control. The hosting control's properties or methods must be called using the Item, SetTemplateDef or Template property.

The following samples shows how you can get the hwnd/handle of the hosting control. In the following sample, the Item property calls the Handle property of the System.Windows.Forms.Control type.
