# DIF_MANUALADDHISTORY

The DIF_MANUALADDHISTORY flag informs the Dialog Manager that the dialog handler will manually add strings to the history list.

### Controls

The DIF_MANUALADDHISTORY flag is applicable to the following dialog items:

Control | Description
--- | ---
DI_EDIT | Edit box.
DI_FIXEDIT | Fixed size edit box.

### Remarks

1. Adding a string to the history list is carried out by the DM_ADDHISTORY message.
2. This flag only extends the DIF_HISTORY flag and has no meaning on its own.

This flag allows to obtain the most complete control on addition of strings to the history list.
