PROPSHEETUI_INFO structure (compstui.h)

  • Artikel

The PROPSHEETUI_INFO structure is used as an input parameter to PFNPROPSHEETUI-typed functions.

Syntax

typedef struct _PROPSHEETUI_INFO {
  WORD            cbSize;
  WORD            Version;
  WORD            Flags;
  WORD            Reason;
  HANDLE          hComPropSheet;
  PFNCOMPROPSHEET pfnComPropSheet;
  LPARAM          lParamInit;
  ULONG_PTR       UserData;
  ULONG_PTR       Result;
} PROPSHEETUI_INFO, *PPROPSHEETUI_INFO;

Members

cbSize

CPSUI-supplied size, in bytes, of the PROPSHEETUI_INFO structure.

Version

CPSUI-supplied version number of the PROPSHEETUI_INFO structure. The current version number is defined by PROPSHEETUI_INFO_VERSION in compstui.h.

Flags

CPSUI-supplied bit flags. The following flag is defined:

Flag Description
PSUIINFO_UNICODE If set, the calling application uses Unicode characters.

Reason

CPSUI-supplied constant specifying the action to be performed on the property sheet by the PFNPROPSHEETUI-typed function to which the PROPSHEETUI_INFO structure was passed. One of the following constants will be supplied:

  • PROPSHEETUI_REASON_DESTROY

  • PROPSHEETUI_REASON_GET_ICON

  • PROPSHEETUI_REASON_GET_INFO_HEADER

  • PROPSHEETUI_REASON_INIT

  • PROPSHEETUI_REASON_SET_RESULT

For information about the meaning of each constant, see the Remarks section of the PFNPROPSHEETUI description.

hComPropSheet

CPSUI-supplied handle to a property sheet group parent. This handle can be passed to CPSUI's ComPropSheet function.

pfnComPropSheet

Address of CPSUI's ComPropSheet function.

lParamInit

Value received as the lParam parameter for the associated PFNPROPSHEETUI-typed function, when the function was first called with a Reason of PROPSHEETUI_REASON_INIT. For information about what this value can be, see the description of PFNPROPSHEETUI.

This value is supplied by CPSUI, and is valid for all Reason values.

UserData

Optional, private value or pointer supplied by the associated PFNPROPSHEETUI-typed function, initially set to zero by CPSUI. If the function stores a value in UserData, then for subsequent calls to the function, the stored value or pointer is unchanged unless changed by the function.

Result

Result value supplied by the associated PFNPROPSHEETUI-typed function, initially set to zero by CPSUI. If the function stores a result value in Result, then for subsequent calls to the function, the stored value is unchanged unless changed by the function.

If the PFNPROPSHEETUI-typed function's address was specified as an argument to CommonPropertySheetUI, the last value stored in Result is returned to CommonPropertySheetUI in the location pointed to by its pResult argument.
