BrowseCallbackProc
[Now Supported on Windows NT]
Specifies an application-defined callback function used with the SHBrowseForFolder function. The browse dialog box calls this function to notify it about
events. The BFFCALLBACK type defines a pointer to this callback function.
int BrowseCallbackProc(
HWND hwnd,
|
| UINT uMsg,
|
| LPARAM lParam,
|
| LPARAM lpData
|
| );
|
|

messages to this window:
BFFM_ENABLEOK
| Enables the OK button if the wParam parameter is nonzero or disables it if wParam is zero.

| 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.
