ACMFORMATCHOOSEHOOKPROC callback function

The acmFormatChooseHookProc function specifies a user-defined function that hooks the acmFormatChoose dialog box. The acmFormatChooseHookProc name is a placeholder for an application-defined name.

Syntax

ACMFORMATCHOOSEHOOKPROC Acmformatchoosehookproc;

UINT Acmformatchoosehookproc(
  HWND hwnd,
  UINT uMsg,
  WPARAM wParam,
  LPARAM lParam
)
{...}

Parameters

hwnd

Window handle for the dialog box.

uMsg

Window message.

wParam

Message parameter.

lParam

Message parameter.

Return Value

None

Remarks

If the hook function processes one of the WM_CTLCOLOR messages, this function must return a handle of the brush that should be used to paint the control background.

A hook function can optionally process the MM_ACM_FORMATCHOOSE message.

You should use this function the same way as you use the Common Dialog hook functions for customizing common dialog boxes.
