CFHookProc Callback Function

Public Function CFHookProc(ByVal hdlg As Long, ByVal uiMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
  ' application-defined code goes here
End Function

Description & Usage

CFHookProc is used to process a Choose Font common dialog box's messages. This hook function allows a program to write its own code to process messages otherwise handled by the Choose Font box. The function does not have to be named CFHookProc -- that is merely the name given to it in discussions about the API.

Return Value

If the function returns 0, the Choose Font dialog box's default message handler processes the message. If the function returns a non-zero value, the Choose Font dialog box's default message handler does not receive the message.

Visual Basic-Specific Issues

Like all callback functions, CFHookProc must be declared Public and be defined in a module.

Parameters

hdlg

A handle to the Choose Font dialog box which the message is for.

uiMsg

The message to be acted upon.

wParam

Additional information about the message.

lParam

Additional information about the message.
