MCI_DGV_OPEN_PARMSA structure (digitalv.h)

The MCI_DGV_OPEN_PARMS structure contains information for the MCI_OPEN command for digital-video devices.

Syntax

typedef struct {
  DWORD_PTR dwCallback;
  UINT      wDeviceID;
  WORD      wReserved0;
  LPSTR     lpstrDeviceType;
  LPSTR     lpstrElementName;
  LPSTR     lpstrAlias;
  DWORD     dwStyle;
  HWND      hWndParent;
  WORD      wReserved1;
} MCI_DGV_OPEN_PARMSA;

wReserved0

lpstrDeviceType

Remarks

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.

Note

The digitalv.h header defines MCI_DGV_OPEN_PARMS as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
