Порядковые номера элементов перечисления TOpenOption
| Код | Наименование | Смысл |
|---|---|---|
| 0 | ofReadOnly |
Selects the Open As Read Only check box by default when the dialog opens. |
| 1 | ofOverwritePrompt |
Generates a warning message if the user tries to select a file name that is already in use, asking whether to overwrite the existing file. (Use with save dialogs.) |
| 2 | ofHideReadOnly |
Removes the Open As Read Only check box from the dialog. |
| 3 | ofNoChangeDir |
After the user clicks OK, resets the current directory to whatever it was before the file-selection dialog opened. |
| 4 | ofShowHelp |
Displays a Help button in the dialog. |
| 5 | ofNoValidate |
Disables checking for invalid characters in file names. Allows selection of file names with invalid characters. |
| 6 | ofAllowMultiSelect |
Allows users to select more than one file in the dialog. |
| 7 | ofExtensionDifferent |
This flag is turned on at runtime whenever the selected filename has an extension that differs from DefaultExt. If you use this flag in an application, remember to reset it. |
| 8 | ofPathMustExist |
Generates an error message if the user tries to select a file name with a nonexistent directory path. |
| 9 | ofFileMustExist |
Generates an error message if the user tries to select a nonexistent file. (only applies to Open dialogs). |
| 10 | ofCreatePrompt |
Generates a warning message if the user tries to select a nonexistent file, asking whether to create a new file with the specified name. |
| 11 | ofShareAware |
Ignores sharing errors and allows files to be selected even when sharing violations occur. |
| 12 | ofNoReadOnlyReturn |
Generates an error message if the user tries to select a read-only file. |
| 13 | ofNoTestFileCreate |
Disables checking for network file protection and inaccessibility of disk drives. Applies only when the user tries to save a file in a create-no-modify shared network directory. |
| 14 | ofNoNetworkButton |
Removes the Network button (which opens a Map Network Drive dialog) from the file-selection dialog. Applies only if the ofOldStyleDialog flag is on. |
| 15 | ofNoLongNames |
Displays 8.3-character file names only. This option is only valid if Options also includes ofOldStyleDialog. |
| 16 | ofOldStyleDialog |
Creates the older style of file-selection dialog. |
| 17 | ofNoDereferenceLinks |
Disables dereferencing of Windows shortcuts. If the user selects a shortcut, assigns to FileName the path and file name of the shortcut itself (the .LNK file), rather than the file linked to the shortcut. |
| 18 | ofEnableIncludeNotify |
(Windows 2000 and later.) Sends CDN_INCLUDEITEM notification messages to the dialog when the user opens a folder. A notification is sent for each item in the newly opened folder. You can use these messages to control which items appear in the folder's item list. |
| 19 | ofEnableSizing |
(Windows 98 and later) Lets the Explorer-style dialog be resized with the mouse or keyboard. By default, the dialog allows this resizing regardless of the value of this option. It is only required if you provide a hook procedure or custom template. (Old style dialogs never permit resizing.) |
| 20 | ofDontAddToRecent |
Prevents the file from being added to the list of recently opened files. |
| 21 | ofForceShowHidden |
Ensures that hidden files are visible in the dialog. |
