Routine Description:

Callback function for the folder browser
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
hwnd : Handle to the browse dialog box. The callback function can
|
||
|
|
send the following messages to this window:
|
||
|
|
|
||
|
|
BFFM_ENABLEOK Enables the OK button if the wParam parameter
|
||
|
|
is nonzero or disables it if wParam is zero.
|
||
|
|
BFFM_SETSELECTION Selects the specified folder. The lParam
|
||
|
|
parameter is the PIDL of the folder to select
|
||
|
|
if wParam is FALSE, or it is the path of the
|
||
|
|
folder otherwise.
|
||
|
|
BFFM_SETSTATUSTEXT Sets the status text to the null-terminated
|
||
|
|
string specified by the lParam parameter.
|
||
|
|
|
||
|
|
uMsg : Value identifying the event. This parameter can be one of the
|
||
|
|
following values:
|
||
|
|
|
||
|
|
0 Initialize dir path. lParam is the path.
|
||
|
|
|
||
|
|
BFFM_INITIALIZED The browse dialog box has finished
|
||
|
|
initializing. lpData is NULL.
|
||
|
|
BFFM_SELCHANGED The selection has changed. lpData
|
||
|
|
is a pointer to the item identifier list for
|
||
|
|
the newly selected folder.
|
||
|
|
|
||
|
|
lParam : Message-specific value. For more information, see the
|
||
|
|
description of uMsg.
|
||
|
|
|
||
|
|
lpData : Application-defined value that was specified in the lParam
|
||
|
|
member of the BROWSEINFO structure.
