MCI_DGV_RECT_PARMS structure (digitalv.h)

The MCI_DGV_RECT_PARMS structure contains parameters for the MCI_FREEZE, MCI_PUT, MCI_UNFREEZE, and MCI_WHERE commands for digital-video devices.

Syntax

typedef struct {
  DWORD_PTR dwCallback;
  POINT     ptOffset;
  POINT     ptExtent;
  RECT      rc;
} MCI_DGV_RECT_PARMS;

Members

dwCallback

The low-order word specifies a window handle used for the MCI_NOTIFY flag.

ptOffset

ptExtent

rc

Rectangle containing positioning information. RECT structures are handled differently in MCI than in other parts of Windows; in MCI, rc.right contains the width of the rectangle and rc.bottom contains its height.

Remarks

The MCI_DGV_FREEZE_PARMS, MCI_DGV_PUT_PARMS, MCI_DGV_UNFREEZE_PARMS and MCI_DGV_WHERE_PARMS structures are identical to the MCI_DGV_RECT_PARMS structure.

When assigning data to the members of this structure, set the corresponding flags in the fdwCommand parameter of the mciSendCommand function to validate the members.
