Members

  • lStructSize
    The size of this structure, in bytes.
  • hwndOwner
    A handle to the owner window.
  • hInstance
    Handle to the module whose executable file contains the dialog box.
  • lpstrFilter
    When ExFlags has the OFN_EXFLAG_THUMBNAILVIEW bit on and lpstrFilter is NULL, dialog displays all image file types supported by the system.
  • lpstrCustomFilter
    Not supported.
  • nMaxCustFilter
    Not supported.

  • nFilterIndex
    Specifies the index of the currently selected filter in the File Types control. The buffer pointed to by lpstrFilter contains pairs of strings that define the filters. The first pair of strings has an index value of 1, the second pair 2, and so on. You can specify an index on input to indicate the initial filter description and filter pattern for the dialog box. When the user selects a file, nFilterIndex returns the index of the currently displayed filter.

    If nFilterIndex is zero, the system uses the first filter in the lpstrFilter buffer.

  • lpstrFile
    Long pointer to a buffer that contains a file name used to initialize the File Name edit control. The first character of this buffer must be NULL if initialization is not necessary. When the GetOpenFileNameEx function returns successfully, this buffer contains the drive designator, path, file name, and extension of the selected file.

    If the buffer is too small, the function returns FALSE. In this case, the first two bytes of the lpstrFile buffer contain the required size, in bytes or characters.

  • nMaxFile
    Specifies the size, in bytes (ANSI version) or 16-bit characters (Unicode version), of the buffer pointed to by lpstrFile. The GetOpenFileNameEx function will return FALSE if the buffer is too small to contain the file information. The buffer should be at least 256 characters long.
  • lpstrFileTitle
    Long pointer to a buffer that receives the file name and extension (without path information) of the selected file. This member can be NULL.
  • nMaxFileTitle
    Specifies the size, in bytes (ANSI version) or 16-bit characters (Unicode version), of the buffer pointed to by lpstrFileTitle. This member is ignored if lpstrFileTitle is NULL.
  • lpstrInitialDir
    When ExFlags has the OFN_EXFLAG_THUMBNAILVIEW bit on and lpstrInitialDir is NULL, dialog defaults to "%MyDocuments%\My Pictures", where %MyDocuments%\My PICTURES is the CSIDL_MYPICTURES special folder
  • lpstrTitle
    When InitialView is FVM_THUMBNAIL and lpstrTitle is NULL, dialog title defaults to 'Select a Picture'.
  • Flags
    A bitmask of flags used to initialize the dialog box.
  • nFileOffset
    Specifies the zero-based offset, in bytes (ANSI version) or 16-bit characters (Unicode version), from the beginning of the path to the file name in the string pointed to by lpstrFile. For example, if lpstrFile points to the following string, c:\dir1\dir2\file.ext, this member contains the value 13 to indicate the offset of the file.ext string.
  • nFileExtension
    Specifies the zero-based offset, in bytes (ANSI version) or 16-bit characters (Unicode version), from the beginning of the path to the file name extension in the string pointed to by lpstrFile. For example, if lpstrFile points to the following string, c:\dir1\dir2\file.ext, this member contains the value 18. If the user did not type an extension and lpstrDefExt is NULL, this member specifies an offset to the terminating null character. If the user typed "." as the last character in the file name, this member specifies zero.
  • lpstrDefExt
    Long pointer to a buffer that contains the default extension. GetOpenFileNameEx appends this extension to the file name if the user fails to type an extension. This string can be any length, but only the first three characters are appended. The string should not contain a period (.). If this member is NULL and the user fails to type an extension, no extension is appended.
  • lCustData
    Not supported.
  • lpfnHook
    Not supported.
  • lpTemplateName
    Not supported.

  • ExFlags
    A bitmask of flags used to initialize the dialog. The following table shows the values, with a description of each value.

    Value Description

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEODEFAULT

    Launch the camera in video mode without changing the audio setting.

    This setting is mutually exclusive with:

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEOONLY

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEOWITHAUDIO

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEOONLY

    Launch the camera in video mode and disable audio recording. The user can enable the audio in options dialog.

    Since audio settings are shared between GetOpenFileNameEx and pimg.exe (the picture viewer application), changing the audio settings here will affect pimg.exe as well.

    This setting is mutually exclusive with:

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEODEFAULT

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEOWITHAUDIO

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEOWITHAUDIO

    Launch the camera in video mode and enable audio recording. The user can disable audio in the options dialog.

    Since audio settings are shared between GetOpenFileNameEx and pimg.exe (the picture viewer application), changing the audio settings here will affect pimg.exe as well.

    This setting is mutually exclusive with:

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEODEFAULT

    OFN_EXFLAG_CAMERACAPTURE_MODE_VIDEOONLY

    OFN_EXFLAG_DETAILSVIEW

    Displays the listview in Details format.

    OFN_EXFLAG_EXPLORERVIEW

    Displays the listview in Explorer format.

    OFN_EXFLAG_HIDEDRMFORWARDLOCKED

    When this flag is set, indicates that Forward Locked content is not displayed in the Picture Picker.

    OFN_EXFLAG_HIDEDRMPROTECTED

    If this flag is set, indicates that DRM-protected files are not displayed in the Picture Picker.

    OFN_EXFLAG_MESSAGING_FILE_CREATE

    Only show picture resolutions or video profiles that are tagged as messaging types.

    OFN_EXFLAG_THUMBNAILVIEW

    Displays the listview in Thumbnails format

  • dwSortOrder
    Specifies the initial sort order. dwSortOrder is currently only supported when ExFlags has the OFN_EXFLAG_THUMBNAILVIEW bit on. The following table shows the values, with a description of each value.

    Value Description

    OFN_SORTORDER_AUTO

    Sort order is implementation-dependent.

    OFN_SORTORDER_DATE

    Sort order is date descending. dwSortOrder defaults to this value when ExFlags is OFN_EXFLAG_THUMBNAILVIEW

    OFN_SORTORDER_NAME

    Sort order is dependent on name.

    OFN_SORTORDER_SIZE

    Sort order is dependent on size.
