Main Page

Determines various editor settings.

int _EdSetEnv(WHANDLE wh, *EDENV theEdEnv)
WHANDLE wh;            /* Handle of editing window. */
*EDENV theEdEnv;         /* Editor settings. */


For the structure of *EDENV, see _EdGetEnv(В ) API Library Routine.

1 is returned if called in a Command or Editor session, otherwise 0 is returned.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.


The following example opens for editing a file specified by a parameter. After indenting the first two lines of the file, it uses _EdSetEnv(В ) to change the size of a tab stop to 6 characters and then to 9 characters.
