  • Article

Notifies the drag-image manager to show or hide the drag image.

Syntax

HRESULT Show(
  [in] BOOL fShow
);

Parameters

[in] fShow

Type: BOOL

A boolean value that is set to TRUE to show the drag image, and FALSE to hide it.

Return value

Type: HRESULT

Returns S_OK if successful, or a COM error value otherwise.

Remarks

This method is used when dragging over a target window in a low color-depth video mode. It allows the target to notify the drag-image manager to hide the drag image while it is painting the window. While you are painting a window that is currently being dragged over, hide the drag image by calling Show with fShow set to FALSE. Once the window has been painted, display the drag image again by calling Show with fShow set to TRUE.
