Members

cbSize

Type: DWORD

The size of the structure, in bytes.

hwndOwner

Type: HWND

A window handle to the owner of the window where the file will be displayed.

iShow

Type: int

The show command for the window. This parameter is one of the SW_ values detailed in ShowWindow.

dwFlags

Type: DWORD

Flags that determine what the file viewer displays. This member can be one or more of the following values.

FVSIF_CANVIEWIT

The file viewer can display the file.

FVSIF_NEWFAILED

The file viewer specified a new file to display, but no viewer could display the file. The file viewer should either continue to display the previous file or terminate.

FVSIF_NEWFILE

A drag-and-drop operation has dropped a file on the file viewer window. The file viewer passes the name of the file to the Shell by copying the name to the strNewFile member. The Shell attempts to load a file viewer that can display the new file.

FVSIF_PINNED

A pinned window exists. A file viewer should either use the pinned window to display the file or set a new pinned window and display the file in it.

FVSIF_RECT

The rect member contains valid data.

rect

Type: RECT

The RECT structure that specifies the size and position of the file viewer's window. This member is valid only if the dwFlags member includes the FVSIF_RECT value.

punkRel

Type: IUnknown*

The address of an interface that has its Release method called by a new file viewer to release the previous file viewer. This member is used when a drag-and-drop operation drops a file on the file viewer's window.

strNewFile

Type: OLECHAR[MAX_PATH]

The address of a string that specifies the name of a new file to display. A file viewer sets this member when a drag-and-drop operation drops a file on the file viewer's window.
