  • Article

The MCI_DGV_WINDOW_PARMS structure contains parameters for MCI_WINDOW command for digital-video devices.

typedef struct {
  DWORD_PTR dwCallback;
  HWND      hWnd;
  WORD      wReserved1;
  UINT      nCmdShow;
  WORD      wReserved2;
  LPSTR     lpstrText;
} MCI_DGV_WINDOW_PARMSA;

Members

wReserved1

nCmdShow

wReserved2

lpstrText

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_WINDOW_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.
