ChooseFont

The ChooseFont function creates a Font common dialog box that enables the user to choose attributes for a logical font. These attributes include a typeface name, style (bold, italic, or regular), point size, effects (underline, strikeout, and text color), and a script (or character set).

BOOL ChooseFont(

LPCHOOSEFONT lpcf	// pointer to structure with initialization data
);

Parameters

lpcf

Pointer to a CHOOSEFONT structure that contains information used to initialize the dialog box. When ChooseFont returns, this structure contains information about the user's font selection.

Return Values

If the user clicks the OK button of the dialog box, the return value is nonzero. The members of the CHOOSEFONT structure indicate the user's selections.

If the user cancels or closes the Font dialog box or an error occurs, the return value is zero. To get extended error information, call the CommDlgExtendedError function, which can return one of the following values:

CDERR_FINDRESFAILURE	CDERR_NOHINSTANCE
CDERR_INITIALIZATION	CDERR_NOHOOK
CDERR_LOCKRESFAILURE	CDERR_NOTEMPLATE
CDERR_LOADRESFAILURE	CDERR_STRUCTSIZE
CDERR_LOADSTRFAILURE	CFERR_MAXLESSTHANMIN
CDERR_MEMALLOCFAILURE	CFERR_NOFONTS
CDERR_MEMLOCKFAILURE

Remarks

You can provide a CFHookProc hook procedure for a Font dialog box. The hook procedure can process messages sent to the dialog box. To enable a hook procedure, set the CF_ENABLEHOOK flag in the Flags member of the CHOOSEFONT structure and specify the address of the hook procedure in the lpfnHook member.

The hook procedure can send the WM_CHOOSEFONT_GETLOGFONT, WM_CHOOSEFONT_SETFLAGS, and WM_CHOOSEFONT_SETLOGFONT messages to the dialog box to get and set the current values and flags of the dialog box.
